EQUIPMENT STERILIZATION

CROSS-REFERENCE TO RELATED APPLICATION

The present application claims priority benefit to a U.S. provisional application entitled“Caddy System for Equipment Sterilization,” which was filed on February 6, 2019, and assigned Serial No. 62/801,818. The entire content of the foregoing provisional application is incorporated herein by reference.

FIELD OF THE DISCLOSURE

The present disclosure generally relates to tray interfacing caddy system and, more generally, a sterilization tray and caddy system for detachably retaining reusable medical devices.

BACKGROUND OF THE DISCLOSURE

Sterilization trays provide a container for retaining reusable medical devices during a patient’s surgical procedure (e.g., during the perioperative process, which may include preoperative care, intraoperative care, and postoperative care) and/or during the central sterile processing process (e.g., autoclave-based steam sterilization). Included within the central sterile processing process are the steps of decontamination, cleaning, assemble and pack, sterilization, storage, distribution/transportation, and aseptic presentation. In hospitals and other health care facilities, a sterile processing department (e.g., Central Sterile Services Department) performs sterilization and other actions on medical devices, equipment, and consumables for subsequent use by medical professionals in the operating room of the hospital (or other health care facility) and also for other aseptic procedures.

Sterilization trays may include a cover, a base, and one or more attachment mechanisms for retaining reusable medical devices. After central sterile processing, sterilization trays may be brought into the operating room, or other venue, to provide a“tool box” for medical professionals to work out of. Despite being used by medical professionals as a“tool box”, sterilization trays provide no feedback, instruction, or ease of modularity to assist medical professionals. Based on the foregoing, a need exists for an effective modular“tool box” that offers flexibility and reliability in the positioning of reusable medical devices in connection with the perioperative process, the central sterile processing process, and/or subsequent access to/use of the sterilized reusable medical devices. Thus, an interest exists for modular sterilization trays and brackets, and related methods of use. These and other inefficiencies and opportunities for improvement are addressed and/or overcome by the assemblies, systems and methods of the present disclosure.

SUMMARY OF THE DISCLOSURE

The present disclosure provides an advantageous assembly for detachably retaining devices. For example, for detachably retaining devices relative to a container (e.g., a caddy system, a tray). In particular, the present disclosure is directed to systems/methods for detachably retaining reusable medical devices and other instruments during the perioperative process and/or during the central sterile processing process. Even more particularly, exemplary assemblies are disclosed that include a tray with at least one caddy system positioned directly or indirectly thereto, for detachable retention of reusable medical devices and/or instruments to facilitate use/exposure during the perioperative process and/or the central sterile processing process.

Engagement feature 20, 22 may be configured and dimensioned to retain, at least in part, at least one medical device (e.g., tibial trials/sizers, tibial base template, reamer). The at least one medical device may be positioned at least partially within engagement feature 20, 22 and may be perpendicular or angled with respect to engagement features 20A-20D and/or surface 12. At least two engagement features 20, 22 may be separated by one or more ribs 24. Rib(s) 24 may partially increase the structural integrity of caddy system 12 (e.g., increased rigidity) and/or may

directly/indirectly ensure that adjacent medical devices (e.g., tibial trials/sizers, tibial base template, reamer) do not touch. Rib(s) 24 may further define at least one boss feature 26.

Boss feature 26 may be configured to partially traverse engagement feature 20, 22.

In an exemplary embodiment, surface 12 may define a plurality of tibial trial engagement features 20A-20D. Tibial trial engagement features 20A-20D may be configured and dimensioned to at least partially engage with one or more tibial trials. Tibial trials may be positioned at least partially within a corresponding engagement feature 20A-20D. In some instances, engagement features 20A-20D may be configured and dimensioned to at least partially engage with one or more variously-sized tibial trials. The corresponding engagement feature 20A-20D may be selected based, in part, on the dimensions (e.g., width, length, height) of the one or more tibial trials. For example, tibial trials having various thicknesses may interface with engagement features 20A-20D having an opening with similar dimensions so as to retain the variously- sized tibial trials (e.g., width of opening is similar to the thickness of the tibial trial). Tibial trials may be positioned perpendicular or angled with respect to engagement features 20A-20D and/or surface 12. Although depicted having four engagement features 20, more or less engagement features 20 are appreciated. Rib 24 may be positioned adjacent to engagement features 20. Rib(s) 24 may further define at least one boss feature 26. Boss feature 26 may be configured to partially traverse engagement feature 20. Boss feature 26 may partially interface with one or more tibial trials to ensure the tibial trial(s) maintain their predetermined position relative to engagement features 20A-20D and/or surface 12 (e.g., perpendicular, angled) and/or may directly/indirectly ensure adjacent medical devices do not contact each other. For example, boss feature 26 may position the one or more tibial trials to promote efficient cleaning and sterilization. Particularly, positioning the one or more tibial trials to have reduced contact with caddy system 10. Caddy system 10 may further define at least one tibial base engagement feature 22. Tibial base engagement feature 22 may be configured and dimensioned to engage with one or more tibial base templates. Tibial base templates may be positioned at least partially within a corresponding engagement feature 22. In some instances, engagement feature 22 may be configured and dimensioned to at least partially engage with one or more variously-sized tibial base templates. The corresponding engagement feature 22 may be selected based, in part, on the dimensions (e.g., width, length, height) of the one or more tibial base templates. Tibial base templates may be positioned perpendicular or angled with respect to surface 12. Rib 24 may be positioned adjacent to engagement feature 22. Rib(s) 24 may further define at least one boss feature 26. Boss feature 26 may be configured to partially traverse

engagement feature 22. Boss feature 26 may partially interface with one or more tibial base templates to ensure the tibial base template(s) maintain its/their position relative to engagement feature 22 and/or surface 12 (e.g., perpendicular, angled) and/or to

directly/indirectly ensure adjacent medical devices do not contact each other. For example, boss feature 26 may position the at least one tibial base template to promote efficient cleaning and sterilization. Particularly, positioning the at least one tibial base template to have reduced contact with caddy system 10.

Caddy system 10 may further define one or more engagement features to at least partially engage with one or more femoral trials. For example, surface 12 may define, in part, opening 28 to engage with a first portion of the femoral trial and opening 32 to engage with a second portion of the femoral trial. Opening 28 and opening 32 may further include stabilization features 30, 34. Stabilization features 30, 34 may directly/indirectly interface with one or more surfaces of the femoral trial. Stabilization features 30, 34 may

directly/indirectly interface with one or more contours of the femoral trial. Stabilization feature 30 may be positioned in close proximity to opening 28 and stabilization feature 34 may be positioned in close proximity to opening 34. Stabilization features 30, 34 may be perpendicular or angled with respect to opening 28, 32 and/or surface 12.

Caddy system 10 may further define one or more upright features 16 positioned with respect to surface 12. Upright feature 16 may be configured and dimensioned to interface with a sidewall of a tray. In a non- limiting example, upright feature 16 may be used as a handle for moving caddy system 10 and/or to directly/indirectly engage with one or more medical devices. However, additional uses are appreciated. Particularly, surface 17 of upright feature 16 may be positioned in close proximity to sidewalls of a tray. Upright feature 16 may further define feature 18 which extends from upright feature 16. Feature 18 may extend angularly or perpendicularly from upright feature 16. Upright feature 16 and feature 18, in combination, may define a handle. Feature 18 may define additional features for ease of handling and/or description of caddy system 10, including but not limited to, user engagement features (e.g., cut-outs, including square, rectangle, semi-circular, among other shapes) and unique characters (e.g., alphanumeric characters, symbols) and unique colors specific to one or more medical devices. Cut-outs may be positioned on opposing sides for engagement by a user. Although upright feature 16 and feature 18 are depicted as extending substantially the width of surface 12, upright feature 16 and/or feature 18 may be larger than or small than the width of surface 12. Upright feature 16 may, in part, define opening 28. Upright feature 16 may further define one or more openings 38 (e.g., slots). Slots 38 may facilitate pass-through of one or more fluids. For example, fluids associated with central sterile processing.

Sidewalls 14 of caddy system 10 may be configured and dimensioned to interface with one or more surfaces of a tray. For example, bottom edge 15 of sidewall 14 may be in direct/indirect contact with a bottom surface of a tray. Sidewalls 14 may further include one or more openings 36 (e.g., slots). Slots 36 may facilitate pass-through of one or more fluids. For example, fluids associated with central sterile processing.

Figs. 2 and 3 schematically depict an advantageous caddy system 50 for detachably retaining and/or containing and/or transporting reusable medical devices and other devices (hereinafter“medical devices”). Caddy system 50 is defined, in part, by surface 52. Caddy system 50 may be further defined by sidewalls 54. Sidewalls 54 extend angularly or perpendicularly from surface 52 so as to partially define a channel(e.g., U-shaped). U-shaped channel may be substantially (or partially) hollow so as to facilitate partial receipt of one or more medical devices. Surface 52 may further define at least one engagement feature for engaging at least one medical device. In an exemplary embodiment, surface 52 may further define a plurality of engagement features for engaging a plurality of medical devices.

Surface 52 may define at least one engagement feature 66, 68 having an opening extending through surface 52 into partial U-shaped channel defined below. Surface 52 may define a plurality of engagement features 66, 68 having corresponding openings extending through surface 52 into partial U-shaped channel defined below. Engagement feature 66, 68 may be configured and dimensioned to retain, at least in part, at least one medical device (e.g., tibial trials/sizers, tibial base template, reamer). The at least one medical device may be positioned at least partially within engagement feature 66, 68 and may be perpendicular or angled with respect to engagement features 66A-66D and/or surface 52. At least two engagement features 66, 68 may be separated by one or more ribs 70, 82. Rib(s) 70, 82 may partially increase the structural integrity of caddy system 52 (e.g., increased rigidity) and/or may directly/indirectly ensure that adjacent medical devices (e.g., tibial trials/sizers, tibial base template, reamer) do not touch. In some embodiments, rib(s) 70, 82 may further define at least one boss feature (not shown). Boss feature (not shown) may be configured to partially traverse engagement feature 66, 68.

In an exemplary embodiment, surface 52 may define a plurality of tibial trial engagement features 66A-66D. Tibial trial engagement features 66A-66D may be configured and dimensioned to at least partially engage with one or more tibial trials. Tibial trials may be positioned at least partially within a corresponding engagement feature 66A-66D. In some instances, engagement features 66A-66D may be configured and dimensioned to at least partially engage with one or more variously-sized tibial trials. The corresponding engagement feature 66A-66D may be selected based, in part, on the dimensions (e.g., width, length, height) of the one or more tibial trials. For example, tibial trials having various thickness may interface with engagement features 66A-66D having an opening with similar dimensions so as to retain the variously- sized tibial trials (e.g., width of opening is similar to the thickness of the tibial trial). Tibial trials may be positioned perpendicular or angled with respect to engagement features 66A-66D and/or surface 52. Although depicted having four engagement features 66, more or less engagement features 66 are appreciated. Rib 70, 82 may be positioned adjacent to engagement features 66. Rib(s) 70, 82 may further define at least one boss feature (not shown). Boss feature (not shown) may be configured to partially traverse engagement feature 66. Boss feature (not shown) may partially interface with one or more tibial trials to ensure the tibial trial(s) maintain their position relative to surface 52 (e.g., perpendicular, angled) and/or to directly/indirectly ensure adjacent medical devices do not contact each other. For example, boss feature (not shown) may position the one or more tibial trials to promote efficient cleaning and sterilization. Particularly, positioning the one or more tibial trials to have reduced contact with caddy system 50.

Caddy system 50 may further define at least one tibial base engagement feature 68. Tibial base engagement feature 68 may be configured and dimensioned to engage with one or more tibial base templates. Tibial base templates may be positioned at least partially within a corresponding engagement feature 68. In some instances, engagement feature 68 may be configured and dimensioned to at least partially engage with one or more variously-sized tibial base templates. The corresponding engagement feature 68 may be selected, in part, based on the dimensions (e.g., width, length, height) of the one or more tibial base templates. Tibial base templates may be positioned perpendicular or angled with respect to engagement feature 68 and/or surface 52. Rib 70, 82 may be positioned adjacent to engagement feature 68. As depicted in Fig. 2, rib 70 may be configured and dimensioned to substantially extend length-wise with engagement features 66A-66D, 68. As depicted in Fig. 3, rib 82 may be configured and dimensioned to partially extend length-wise with engagement features 66A- 66D, 68. Rib(s) 70, 82 may further define at least one boss feature (not shown). Boss feature (not shown) may be configured to partially traverse engagement feature 68. Boss feature (not shown) may partially interface with one or more tibial base templates to ensure the tibial base template(s) maintain its/their position relative to surface 52 (e.g., perpendicular, angled) and/or to directly/indirectly ensure adjacent medical devices do not contact each other. For example, boss feature (not shown) may position the at least one tibial base template to promote efficient cleaning and sterilization. Particularly, positioning the at least one tibial base template to have reduced contact with caddy system 50.

Caddy system 50 may further define support feature 64. Support feature 64 may be positioned in close proximity to engagement features 66, 68. Support feature 64 may be positioned within U-shaped channel and below engagement features 66, 68 positioned with respect to surface 52. Support feature 64 may be perpendicular or angled with respect to engagement features 66A-66D, 68 and/or surface 52. Support feature 64 may further define openings 67A-67D. Although four openings 67A-67D are depicted, more or less openings are appreciated. Openings 67A-67D may be configured and dimensioned to

directly/indirectly engage with one or more medical devices. For example, openings 67 A- 67D may correspond with engagement features 66A-66D and/or 68 and may be configured to engage with one or more tibial trials and/or tibial base template. The position of openings 67A-67D may depend, in part, on whether the one or more tibial trials/tibial base template are intended to be positioned perpendicular or angled with respect to engagement features 66 A- 66D, 68 and/or surface 52. For example, where one or more tibial trials/tibial base template are intended to be positioned perpendicular or angled with respect to engagement features 66A-66D, 68 and/or surface 52, openings 67A-67D may be aligned with or offset from engagement features 66A-66D, 68 positioned above.

For instance, if tibial trials/tibial base template were intended to be perpendicular, as described above, openings 67A-67D may be aligned with engagement features 66A-66D, 68. Thus, engagement of tibial trials/tibial base template with their corresponding engagement features 66A-66D, 68 and openings 67A-67D would result in tibial trials/tibial base template being substantially perpendicular with respect to engagement features 66A-66D, 68 and/or surface 52. In another instance, if tibial trials/tibial base template were intended to be angled, as described above and depicted in Fig. 4, openings 67A-67D may be positioned offset from engagement features 66A-66D, 68. Thus, engagement of tibial trials 102A-102D and/or tibial base template 104 with their corresponding engagement features 66A-66D, 68 and openings 67A-67D would result in tibial trials/tibial base template being substantially angled with respect to engagement features 66A-66D, 68 and/or surface 52.

Caddy system 50 may further define one or more engagement features to at least partially engage with one or more femoral trials (See Fig. 4). For example, surface 52 may define, in part, opening 72 to engage with a first portion of the femoral trial and opening 76 to engage with a second portion of the femoral trial. Opening 72 and opening 76 may further include stabilization features 74, 78. Stabilization features 74, 78 may directly/indirectly interface with one or more surfaces of the femoral trial. Stabilization features 74, 78 may directly/indirectly interface with one or more contours of the femoral trial. Stabilization feature 74 may be positioned in close proximity to opening 72 and stabilization feature 78 may be positioned in close proximity to opening 76. Stabilization features 74, 78 may be perpendicular or angled with respect to opening 72, 76 and/or surface 52.

Caddy system 50 may further define one or more upright features 58 positioned with respect to surface 52. Upright feature 58 may be configured and dimensioned to interface with a sidewall of a tray. In a non- limiting example, upright feature 58 may be used as a handle for moving caddy system 50 and/or to directly/indirectly engage with one or more medical devices. However, additional uses are anticipated. Particularly, surface 60 of upright feature 58 may be positioned in close proximity to sidewalls of a tray. Upright feature 58 may further define feature 62 which extends from upright feature 58. Feature 62 may extend angularly or perpendicularly from upright feature 58. Upright feature 58 and feature 62, in combination, may define a handle. Feature 62 may define additional features for ease of handling and/or description of caddy system 50, including but not limited to, user engagement features (e.g., cut-outs, including square, rectangle, semi-circular, among other shapes) and unique characters (e.g., alphanumeric characters, symbols) and unique colors specific to one or more medical devices. Cut-outs may be positioned on opposing sides for engagement by a user. Although upright feature 58 and feature 62 are depicted as extending substantially the width of surface 52, upright feature 58 and/or feature 62 may be larger than or smaller than the width of surface 52. Upright feature 58 may, in part, define opening 72. Upright feature 58 may further define one or more openings 80 (e.g., slots). Slots 80 may facilitate pass-through of one or more fluids. For example, fluids associated with central sterile processing.

Sidewalls 54 of caddy system 50 may be configured and dimensioned to interface with one or more surfaces of a tray. For example, bottom edge 56 of sidewall 54 may be in direct/indirect contact with a bottom surface of a tray. Sidewalls 54 may further include one or more openings (not shown) (e.g., slots). Slots (not shown) may facilitate pass-through of one or more fluids. For example, fluids associated with central sterile processing.

In another embodiment, tibial trials 102A-102D and/or tibial base template 104 may be initially positioned within corresponding engagement feature 20A-20D, 22. Tibial trials 102A-102D and/or tibial base template 104 may be initially positioned within corresponding engagement feature 20A-20D, 22 in a substantially perpendicular configuration. Then, tibial trials 102A-102D and/or tibial base template 104 may be pivoted relative to corresponding engagement feature 20A-20D and/or surface 12 to releasably lock tibial trials 102A-102D and/or tibial base template 104 relative to engagement feature 20A-20D, 22, as depicted in Figs. 4-7. Tibial trials 102A-102D and/or tibial base template 104 may be releasably locked relative to surface 12. At least one boss feature 26 may, in part, releasably lock tibial trials 102A-102D and/or tibial base template 104 with respect to surface 12.

In another embodiment, tibial trials 102A-102D and/or tibial base template 104 may be initially positioned within corresponding engagement feature 66A-66D, 68. Tibial trials 102A-102D and/or tibial base template 104 may be initially positioned within corresponding engagement feature 66A-66D, 68 in a substantially perpendicular configuration. Then, tibial trials 102A-102D and/or tibial base template 104 may be pivoted relative to corresponding engagement feature 66A-66D and/or surface 52 to releasably lock tibial trials 102A-102D and/or tibial base template 104 relative to engagement feature 66A-66D, 68, as depicted in Figs. 4-7. Tibial trials 102A-102D and/or tibial base template 104 may be releasably locked relative to surface 52. At least one boss feature (not shown) may, in part, releasably lock tibial trials 102A-102D and/or tibial base template 104 with respect to surface 52.

Figs. 5-7 schematically depict assembly 200 including a plurality of caddy systems 10, 50 positioned adjacent to each other and with respect to tray 202. Although depicted as a plurality of caddy systems 10, 50, one or more cavity systems 10, 50 may be utilized without departing from the spirit/scope of this disclosure. Depending on the situation, tray 202 may be partially filled or completely filled with one or more caddy system(s) 10, 50.

Tray 202 includes bottom 204 and sidewalls 206 which partially define an interior. Interior is configured and dimensioned to receive one or more caddy systems 10, 50.

Particularly, bottom edge 15, 56 of sidewall 14, 54 of caddy system 10, 50 may be at least partially in direct/indirect contact with bottom 204 of tray 202. More particularly, bottom edge 15, 56 may define features/elements that at least partially interface with bottom 204.

For example, features/elements that enable fluid to pass-through (e.g., fluid from the central sterile process) and/or that interface caddy system 10, 50 with bottom 204. Tray 202 farther includes a plurality of perforations 208 positioned with respect to bottom 204 and/or sidewalls 206. Perforations 208 may assist with securing one or more caddy system(s) 10, 50 to tray 202. However, caddy system 10, 50 may be positioned within the interior of tray 202 without being affixed either directly/indirectly by one or more perforations 208.

In an exemplary embodiment, caddy system 10, 50 may be positioned within the interior of tray 202. The quantity of caddy systems 10, 50 positioned within tray 202 may depend on the desired perioperative process and/or central sterile processing process. Thus, one caddy system 10, 50 may be positioned within tray 202 or a plurality of caddy systems 10, 50 may be positioned within tray 202. If two or more caddy systems 10, 50 are positioned within one tray 202, one or more caddy systems 10, 50 may be removed from tray 202 without disturbing one or more of the remaining caddy systems 10, 50. Caddy system 10, 50 may be in direct/indirect contact with one or more sidewalls 206 and bottom 204. Caddy system 10, 50 may be in direct/indirect contact with two sidewalls 206 and bottom 204.

Caddy system 10, 50 may be in direct/indirect contact with two sidewalls 206, bottom 204 and at least one adjacent caddy system 10, 50.

Caddy system 10, 50 may be releasably contained within tray 202 by one or more posts 210 positioned with respect to one or more perforations 208. Particularly, one or more posts 210 may be in direct/indirect contact with one or more corners 38, 82 of caddy system 10, 50. In some embodiments, one post 210 may be in direct/indirect contact with at least two caddy systems 10, 50. In other embodiments, one post 210 may be in di reel/ indirect contact with up to four caddy systems 10, 50. Post 210 and/or caddy system 10, 50 (e.g., corner 38, 82) may include features/elements to facilitate engagement between post 210 and caddy system 10, 50.

With reference to Figs. 8A-8B, advantageous post 210 may include body 252 and tray engagement feature (e.g., clip) 254. Body 252 and clip 254 may be fabricated to form a unitary component (e.g., molding, casting, extruding) or may be assembled together from individual components. In one embodiment, where body 252 and clip 254 are a single fabricated component, some features of one component may extend through or blend into the other component. Therefore, it should be understood that the labels“body” and“clip” are merely explanatory and are not intended to rigidly define post 210.

Body 252 may be fabricated such that the ratio between the height and the cross- section favors the height. However, the ratio between the height and cross-section may be equal or may favor the cross-section, depending on the application, as will be evident from this disclosure. The cross-section of body 252 may be fabricated from a variety of shapes, including a quadrilateral (e.g., square, rectangle, diamond), a circle, a triangle, a balbis (“H- shape”), a cross (“plus sign”), among others, as will be apparent based on the intended purpose of this disclosure.

In an exemplary embodiment, body 252 has a height that is greater than the cross- sectional distance and a cross-section with a substantially cross shape (“plus sign”). Body 252 may further include at least one attachment feature. Attachment feature may include at least one slot 256 and optionally at least one hole 264. At least one slot 256 is defined by two side walls 258, 260. At least one hole 264 may be centrally located on top face 266 and extend some distance inward from top face 266 to clip portion 254. Slot 256 may extend some distance from top surface 266 towards clip 254. In some embodiments, slot 256 extends from top surface 266 through at least a portion of clip 254. The depth of slot 256 may be further defined by the distance between face 262 and slot bottom 268. Slot 256 may be recessed a distance below top face 266, such that slot top 270 is the top of slot 256. The cavity between slot top 270 and top face 266 is configured and dimensioned to accept a portion of partition, further described below. Slot 256, as defined by side walls 258, 260 and slot bottom 268, may be square, rectangle, semi-circular, among other shapes.

Body 252 may further include additional attachment features. For example, alternatively located holes, dimples, slots, cavities, fasteners, etc., as can be appreciated in view of this disclosure. It is a desire to illustrate that post 210 and at least a portion of caddy system 10, 50 may be releasably attached. As such, attachment features that provide attachment and detachment of at least a portion of caddy system 10, 50 from post 210 are appreciated. Attachment features may further include features for retaining one or more corners 38, 82 of caddy system 10, 50. Interfacing corners 38, 82 may be fixedly attached to post 210 and/or may be positioned in close proximity to post 210 so as to retain caddy system 10, 50 from at least partial movement without fixedly engaging caddy system 10, 50.

Clip 254 may include clip body 272 and two symmetrically adjacent arms 274, located on either side of clip body 272. Clip body 272 may be coplanar with face 262. In some embodiments, side walls 258, 260 and clip body 272 may be the same component, as depicted in Figs. 8A-8B. In other embodiments, clip 254 may be a separate component. As mentioned above, slot 256 may extend at least partially through clip 254. In one embodiment, slot 256 may extend from top surface 266 through base 273 on clip body 272. Surface 276 connects arm 274 to clip body 272 by way of shoulder 278. Located above arm base 280 is cavity 282, which provides a tray engagement feature to directly or indirectly attach to at least one tray perforation 208. The disclosed interface features of cavity 282 may include back face 284, upper extension 286, and lower extension 288, which collectively form cavity 282. In relation to back face 284, the length of lower extension 288 may be shorter than the length of upper extension 286, as depicted. Lower extension 288 having a shorter length enables an easier installation and removal from tray perforations without sacrificing clip engagement. However, in another embodiment, upper extension 286 and lower extension 288 may have similarly dimensioned lengths.

In exemplary operation, at least a portion of cavity 282 captures a portion of a tray perforation. To ensure clip 254 does not shift after installation with tray 202, back face 284 is under spring load in contact with an inside wall of a perforation. Furthermore, upper extension 286 and lower extension 288 may be in close proximity to tray 202. Particularly, upper extension 286 and lower extension 288 may at least partially engage with at least one surface of tray 202. Even more particularly, upper extension 286 may at least partially engage with the interior surface of tray 202 and lower extension 288 may at least partially engage with the exterior surface of tray 202.

In one example, by simultaneously compressing arms 274, such that arms 274 at least partially flex, face 290 moves closer to outer face 292 on clip body 272 and the distance between back face 284 on either arm 274 is reduced. Reduction of the distance between back face 284 on either arm 274 enables cavity 282 to be engaged with the respective perforations. Once arms 274 are released into their relaxed position, back face 284 will be in contact with a desired engagement surface on the respective perforation. Particularly, since the resting distance between back faces 284 is greater than the distance between the engagement surfaces (e.g., inside wall), arms 274 remain in slight compression and therefore apply a spring load to the engagement surface of the respective perforation. In another example, by individually compressing arms 274, such that arms 274 at least partially flex, one cavity 282 may be engaged with the respective perforation. Upon engagement of one cavity 282, second cavity 282 may be engaged with the perforation. Aside from the method to engage clip 254 with a tray (e.g., individual arm compression or simultaneous arm compression), the engagement with the perforation is substantially similar. Therefore, arms 274 apply a spring load to the desired engagement surface on the respective perforation. Of note, attachment is not to be limited to a tray; rather, attachment may further be accomplished with the sidewalls and the cover (not shown). For purposes of the present disclosure, when one of a tray, a sidewall(s) and/or a cover are mentioned, the others not mentioned are included, unless otherwise stated.

In an exemplary embodiment, arms 274 may include a semi-circular feature 294 located on the outside surface of arm 274, opposite surface 290. Semi-circular feature 294 may provide a specific location for a user to place their fingers to assist in compressing arms 274 for insertion or removal from a tray.

Caddy system 10, 50 may be configured and dimensioned so as to suspend medical devices a distance above bottom 204, as particularly depicted in Fig. 7. Fig. 7 depicts medical devices positioned on an angle, as thoroughly discussed above. Positioning medical devices on an angle enables taller medical devices to fit substantially with the interior of tray 202 such that a lid may be positioned on top of tray 202. Particularly, tibial trials 102A-102D and/or tibial base template 104 may be positioned on an angle. Positioning medical devices (e.g., tibial trials and tibial base template) perpendicularly or angularly, as described above, promotes better cleaning and sterilization, a shortcoming of current packaging configurations (e.g., medical devices positioned laying down).

Figs. 9-15 schematically depict an advantageous caddy system 300 for detachably retaining and/or containing and/or transporting reusable medical devices and other devices (hereinafter“medical devices”). Caddy system 300 is defined, in part, by surface 302.

Caddy system 300 may be further defined by sidewalls 304. Sidewalls 304 extend angularly or perpendicularly from surface 302 so as to define a channel (e.g., U-shaped). U-shaped channel may be substantially (or partially) hollow so as to facilitate partial receipt of one or more medical devices. Surface 302 may further define at least one engagement feature for engaging at least one medical device. In an exemplary embodiment, surface 302 may further define a plurality of engagement features for engaging a plurality of medical devices. Fig. 15, specifically, depicts three advantageous engagement features side-by-side for ease of comparison.

Surface 302 may define at least one engagement feature 306 having an opening extending through surface 302 into channel (e.g., U-shaped) defined below. Surface 302 may define a plurality of engagement features 306 having corresponding openings extending through surface 302 into U-shaped channel, defined below. Engagement feature 306 may be configured and dimensioned to retain, at least in part, at least one medical device (e.g., tibial trials/sizers, tibial base template, reamer). The at least one medical device may be positioned at least partially within engagement feature 306 and may be perpendicular or angled with respect to engagement features 306 and/or surface 302. At least two engagement features 306 may be positioned a predetermined distance from each other. Thus, surface 302 may separate at least two engagement features 306, which may partially increase the structural integrity of caddy system 300 (e.g., increased rigidity) and/or may ensure that adjacent medical devices (e.g., tibial trials/sizers, tibial base template, reamer) do not touch.

Engagement features 306 may further define at least one boss feature 320, 322. Boss feature 320, 322 may be configured to partially traverse engagement feature 306. Caddy system 300 may further define one or more openings 326, 328 (e.g., slots). Slots 326, 328 may facilitate pass-through of one or more fluids. For example, fluids associated with central sterile processing.

In an exemplary embodiment, surface 302 may define a plurality of reamer engagement features 306. Reamer engagement features 306 may be configured and dimensioned to at least partially engage with one or more reamers. Reamers may be positioned at least partially within a corresponding engagement feature 306. In some instances, engagement features 306 may be configured and dimensioned to at least partially engage with one or more variously-sized reamers. The corresponding engagement feature 306 may be selected based, in part, on the dimensions (e.g., width, length, height) of the one or more reamers. For example, reamers having various diameters and/or heights may interface with engagement features 306 having an opening (e.g., semispherical opening) with similar dimensions so as to retain the variously-sized reamers (e.g., width and diameter of opening are similar to the height and the diameter of the reamer, respectively). Caddy system 300 may engage with a plurality of variously-sized reamers. Reamers may be positioned perpendicular or angled with respect to engagement features 306 and/or surface 302.

Although depicted having between three and six engagement features 306, more or less engagement features 306 are appreciated.

Engagement feature 306 may be a semispherical opening defining a curved edge 308 and a connecting edge 310. Semispherical opening of engagement feature 306 may be sized to at least partially engage with one or more reamers of corresponding size. Engagement feature 306 may further define recessed portion 312 for receipt of one or more reamer features and/or surfaces, as will be discussed in more detail below. Connecting edge 310 may define recessed portion 312, which may be positioned of equal distance between the outer edges of engagement feature 306.

Engagement feature 306 may further define one or more boss features 320, 322. Engagement feature 306 may define at least two boss features 320. Engagement feature 306 may define at least one boss feature 322. Boss feature 320, 322 may be configured to partially traverse engagement feature 306. Boss feature 320, 322 may partially interface with one or more reamers to ensure the reamer(s) maintain its/their position relative to engagement features 306 and/or surface 302 (e.g., perpendicular, angled) and/or to directly/indirectly ensure adjacent medical devices do not contact each other. For example, boss feature 320, 322 may position the one or more reamers to allow for enhanced cleaning. Particularly, positioning the one or more reamers to have reduced contact with caddy system 300.

Caddy system 300 may further include one or more tray engagement features 315. Tray engagement feature 315 may directly/indirectly engage with one or more features on tray 202. Tray engagement features 315 may interface with one or more posts 210, which may be mounted with respect to tray 202. Tray engagement feature 315 defines sidewall edge 316 and surface edge 318. Sidewall edge 316 may be configured and dimensioned to engage with slot 256 of post 210. Surface edge 318 may be configured to contact one or more surfaces of post 210. Caddy system 300 may interface with one or more posts 210. Caddy system 300 may interface with two or more posts 210. Caddy system 300 may interface with four posts 210, one in each corner of caddy system 300.

With specific reference to Figs. 10 and 11, boss feature 320 may extend from connecting edge 310 and partially traverse engagement feature 306 a predetermined distance. Boss feature 320 may be configured to partially engage with one or more reamer features and/or surfaces, as will be discussed in more detail below. A surface of boss feature 320 may be planar with surface 302. Boss feature 320 may extend from connecting edge 310 in a variety of shapes, including but not limited to, quadrilateral (e.g., square, rectangle, diamond), elliptical, circular, and any combination thereof. For example, boss feature 320 may be a combination of quadrilateral and circular. In some embodiments, two boss features 320 may extend from connecting edge 310 and partially traverse engagement feature 306 a

predetermined distance. The two boss features 320 may be positioned a predetermined distance from each other.

With specific reference to Fig. 11, boss feature 322 may extend from curved edge 308 and partially traverse engagement feature 306 a predetermined distance. Boss feature 322 may be configured to partially engage with one or more reamer features and/or surfaces, as will be discussed in more detail below. A surface of boss feature 322 may be planar with surface 302. Boss feature 322 may extend from curved edge 308 in a variety of shapes, including but not limited to, quadrilateral (e.g., square, rectangle, diamond), elliptical, circular, and any combination thereof. In some embodiments, two boss features 322 may extend from curved edge 308 and partially traverse engagement feature 306 a predetermined distance. The two boss features 322 may be positioned a predetermined distance from each other. Engagement feature 306 may further define one or more corner engagement features 324. Corner engagement features 324 may interface with one or more surfaces and/or features of a reamer. Engagement feature 306 may define two corner engagement features 324 in close proximity to connecting edge 310.

Caddy system 300 may further define one or more upright features (not shown) positioned with respect to surface 302, as discussed above. Upright feature (not shown) may be configured and dimensioned to interface with sidewall 206 of tray 202. In a non-limiting example, upright feature (not shown) may be used as a handle for moving caddy system 300 and/or to directly/indirectly engage with one or more medical devices. However, additional uses are appreciated. Particularly, one or more surfaces of upright feature may be positioned in close proximity to sidewalls of tray 202. Upright feature (not shown) may further define a feature that extends from upright feature (not shown). Feature (not shown) may extend angularly or perpendicularly from upright feature (not shown). Upright feature (not shown) and feature (not shown), in combination, may define a handle. Feature (not shown) may define additional features for ease of handling and/or description of caddy system 300, including but not limited to, user engagement features (e.g., cut-outs, including square, rectangle, semi-circular, among other shapes) and unique characters (e.g., alphanumeric characters, symbols) and unique colors specific to one or more medical devices. Cut-outs may be positioned on opposing sides for engagement by a user. Upright feature (not shown) and feature (not shown) may extend substantially the width of surface 302. In another embodiment, upright feature (not shown) and feature (not shown) may be larger than or smaller than the width of surface 302. Upright feature (not shown) may, in part, define one or more openings (e.g., slots, engagement features). Slots (not shown) may facilitate pass through of one or more fluids. For example, fluids associated with central sterile processing.

Figs. 16-25B schematically depict assembly 400 including a plurality of caddy systems 300 positioned adjacent to each other and with respect to tray 202. Although depicted as a plurality of caddy systems 300, one or more cavity systems 300 may be utilized without departing from the spirit/scope of this disclosure. Depending on the situation, tray 202 may be partially filled or completely filled with one or more caddy system(s) 300.

As discussed above, tray 202 includes bottom 204 and sidewalls 206 which partially define an interior. Interior is configured and dimensioned to receive one or more caddy systems 300. Particularly, bottom edge 314 of sidewall 304 of caddy system 300 may be at least partially in direct/indirect contact with bottom 204 of tray 202. More particularly, bottom edge 314 may define features/elements that at least partially interface with bottom 204. For example, features/elements that enable fluid to pass-through (e.g., fluid from the central sterile process) and/or that interface caddy system 300 with bottom 204. Tray 202 further includes a plurality of perforations 208 positioned with respect to bottom 204 and/or sidewalls 206. Perforations 208 may assist with securing one or more caddy system(s) 300 to tray 202. However, caddy system 300 may be positioned within the interior of tray 202 without being affixed either directly/indirectly by one or more perforations 208.

In an exemplary embodiment, caddy system 300 may be positioned within the interior of tray 202. The quantity of caddy systems 300 positioned within tray 202 is may depend on the desired perioperative process and/or central sterile processing process. Thus, one caddy system 300 may be positioned within tray 202 or a plurality of caddy systems 300 may be positioned within tray 202. If two or more caddy systems 300 are positioned within one tray 202, one or more caddy systems 300 may be removed from tray 202 without disturbing one or more of the remaining caddy systems 300. Caddy system 300 may be in direct/indirect contact with one or more sidewalls 206 and bottom 204. Caddy system 300 may be in direct/indirect contact with two sidewalls 206 and bottom 204.

In some embodiments, one post 210 may be in direct/indirect contact with at least two caddy systems 300. In other embodiments, one post 210 may be in direct/indirect contact with up to four caddy systems 300. Post 210 and/or caddy system 300 (e.g., corner 315) may include features/elements to facilitate engagement between post 210 and caddy system 300.

Reference is made to the above post 210 description.

Caddy system 300 may be configured and dimensioned to interface with one or more medical devices (e.g., reamers, tibial base template, tibial trials/sizers). Caddy system 300 may be configured and dimensioned to interface with a plurality of medical devices (e.g., reamers, tibial base template, tibial trials/sizers). Caddy system 300 may be configured and dimensioned to interface with a plurality of medical devices (e.g., reamers, tibial base template, tibial trials/sizers) of various sizes. The one or more medical devices may be initially positioned within one or more corresponding engagement features and then the one or more medical devices may be pivoted to releasably lock relative to engagement feature 306. The one or more medical devices may be positioned at least partially within engagement feature 306 and may be perpendicular or angled with respect to engagement feature 306 and/or surface 302. In an exemplary embodiment, caddy system 300 may be configured and dimensioned to interface with one or more reamers 402. Assembly 400 includes caddy system 300, which may be configured and dimensioned to interface with tray 202 and optionally with one or more reamers 402.

Reamer 402 may further include one or more bars 408, 410 positioned relative to cavity 406. Bars 408, 410 may be positioned in a substantially cross shape (“plus sign”). However, additional configurations are appreciated. In a non-limiting example, but for ease of explanation, bar 408 may be horizontal and bar 410 may be vertical. Bars 408, 410 may promote stability of reamer 402. Bars 408, 410 may further include one or more surfaces 412 for displaying identifying characteristics. The disclosed identifying characteristics may include, but are not limited to, unique characters (e.g., symbols, alphanumeric characters) and/or corresponding colors. The identifying characteristics may be visible to a user when reamer 402 is positioned at least partially within engagement feature 306.

Engagement feature 306 may partially interface with one or more features and/or surfaces of reamer 402, including but not limited to, outer surface 404, inner cavity 406, bars 408, 410, cavity edge 414 and any combination thereof. Reamer 402 may be positioned at least partially within engagement feature 306 and may be perpendicular or angled with respect to engagement feature 306 and/or surface 302.

Cavity edge 414 may be in at least partial contact with one or more corner engagement features 324.

Reamer 402 may be positioned within corresponding engagement feature 306.

Reamer 402 may be positioned within corresponding engagement feature 306 in a substantially perpendicular configuration. In one embodiment, reamer 402 may be initially positioned within corresponding engagement feature 306. Reamer 402 may be initially positioned within corresponding engagement feature 306 in a substantially perpendicular configuration, as depicted in Fig. 20 A. Then, reamer 402 may be pivoted relative to engagement feature 306 and/or surface 302 to releasably lock reamer 402 relative to engagement feature 306 and/or surface 302, as depicted in Fig. 20B. Reamer 402 may be releasably locked relative to engagement feature 306, in part, by recessed portion 312 being in at least partial contact with vertical bar 410, boss feature 320 being in at least partial contact with horizontal bar 408 and/or outer surface 404 being in at least partial contact with curved edge 308 or boss feature 322. In one example, the one or more reamers may be locked with respect to the disclosed caddy system to ensure the one or more reamers remain positioned with respect to caddy system 300 during transportation.

Caddy system 300 may be configured and dimensioned so as to suspend medical devices a distance above bottom 204. Positioning reamers 402 on an angle enables larger reamers 402 to fit substantially with the interior of tray 202 such that a lid may be positioned on top of tray 202. Positioning reamers 402 perpendicularly or angularly, as described above, promotes better cleaning and sterilization, a shortcoming of current packaging configurations (e.g., medical devices positioned laying down).

Caddy system 10, 50, 300 may be removed from tray 202 for use as a separate“tool box”. The separate tool box may include medical devices that compliment each other and/or that are apart of a set. Caddy system 10, 50, 300 may be customized to a user’s preference (e.g., to include a plurality of medical device sizes). In an exemplary embodiment, a plurality of caddy systems 10, 50, 300 may be positioned within one tray. The plurality of caddy systems may be configured and adapted to retain a plurality of variously-sized medical devices (e.g., femoral trial, reamer, tibial base template, tibial trials/sizers). If two or more caddy systems 10, 50, 300 are positioned within one tray 202, one or more caddy systems 10, 50, 300 may be removed from bay 202 without disturbing one or more of the remaining caddy systems 10, 50, 300.

In one non-limiting example, a plurality of caddy systems 10, 50, 300 are positioned within tray 202 for use during surgery. During surgery, one or more caddy systems 10, 50, 300 may be removed from tray 202 and delivered to the operating location, while tray 202 remains stationary. Delivery of the one or more caddy systems 10, 50, 300 provides ease of transportation by a user with a reduced risk in dropping one or more medical devices. In part, caddy systems 10, 50, 300 promote efficiency during a patient’s surgical procedure (e.g., during the perioperative process, which may include preoperative care, intraoperative care, and postoperative care) and/or during the central sterile processing process (e.g., autoclave-based steam sterilization). The disclosed caddy system 10, 50, 300 may be fabricated from one or more materials that is/are impervious to the harsh conditions of central sterile processing processes.

However, materials that are not impervious to the conditions of central sterile processing processes may be coated so as to make them resistant, i.e., able to withstand sterilization conditions (e.g., coating, anodizing, and/or plating). The disclosed caddy system 10, 50, 300 may be fabricated from plastic (e.g., thermoplastic), silicone, or metal (e.g., aluminum).

Although the present disclosure has been described with reference to exemplary implementations, the present disclosure is not limited by or to such exemplary

implementations. Rather, various modifications, refinements and/or alternative

implementations may be adopted without departing from the spirit or scope of the present disclosure.
