The present inventive concepts generally relate to the field of robotic systems, and more particularly, to articulating robotic systems, robotic system user interfaces, human interface devices for controlling robotic systems and methods of controlling robotic systems.

BACKGROUND

As less invasive medical techniques and procedures become more widespread, medical professionals, such as surgeons, may employ snake-like robotic systems having highly articulated multi-link probes to access parts of the human anatomy that were otherwise difficult to reach. With the use of such robotic systems, medical professionals may be able to replace open-cavity surgical procedures with less invasive procedures.

Robotic systems of the type described above may have multiple device channels for guiding a variety of surgical and/or interventional tools during surgical procedures; however, these tools generally comprise hand operated levers and handles, which are separate from the control device of the robotic system.

DETAILED DESCRIPTION OF EMBODIMENTS

The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting of the inventive concepts. As used herein, the singular forms "a," "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises,"

"comprising," "includes" and/or "including," when used herein, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. It will be understood that, although the terms first, second, third etc. may be used herein to describe various limitations, elements, components, regions, layers and/or sections, these limitations, elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one limitation, element, component, region, layer or section from another limitation, element, component, region, layer or section. Thus, a first limitation, element, component, region, layer or section discussed below could be termed a second limitation, element, component, region, layer or section without departing from the teachings of the present application.

It will be further understood that when an element is referred to as being "on" or "connected" or "coupled" to another element, it can be directly on or above, or connected or coupled to, the other element or intervening elements can be present. In contrast, when an element is referred to as being "directly on" or "directly connected" or "directly coupled" to another element, there are no intervening elements present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g., "between" versus "directly between," "adjacent" versus "directly adjacent," etc.). When an element is referred to herein as being "over" another element, it can be over or under the other element, and either directly coupled to the other element, or intervening elements may be present, or the elements may be spaced apart by a void or gap.

The HID 210 may include a hand-operated control device 211, and the hand-operated control device 21 1 may include one or more joysticks 315, 320. The joysticks 315, 320 may be movable with respect to the hand-operated control device 211. For example, the joysticks 315, 320 may be moveable with respect to the hand-operated control device 211 in at least one or more of the directions selected from the group consisting of: the X direction, the Y direction, the Z direction and the Θ direction (see for example, the X direction, the Y direction and the Z direction illustrated in FIG. 5A). Movements of the one or more joysticks 315, 320 with respect to the hand-operated control device 21 1 may generate control signals for manipulating one or more of the surgical tools 140, 140a-b of the system 100. For example, a movement of one of the joysticks 315, 320 with respect to the hand-operated control device 21 1 in the X direction may manipulate and/or articulate an articulation region of one of the surgical tools 140, 140a-b in a second direction D2 (see for example, the second direction D2 illustrated in FIG 4). A movement of one of the joysticks 315, 320 with respect to the hand-operated control device 21 1 in the Y direction may manipulate and/or articulate an articulation region of one of the surgical tools 140, 140a-b in a third direction D3 (see for example, the third direction D3 illustrated in FIG 4). A movement of one of the joysticks 315, 320 with respect to the hand-operated control device 21 1 in the Z direction may manipulate and/or advance or retract one of the surgical tools 140, 140a-b in a first direction Dl (see for example, the first direction Dl illustrated in FIG 4). Alternatively or additionally, one or more input devices, such as hand-operated control device 21 1 may be constructed and arranged to move, such that movement of the entire input device can be used to generate a control signal (e.g. via integral sensors such as accelerometers).

A first joystick of the one or more joysticks 315, 320 may be configured to generate the second control signal. As described above, the controller 1 15 may be constructed and arranged to manipulate (e.g., advance or retract, steer, actuate) one of the surgical tools 140, 140a-b in response to the second control signal. For example, the controller 1 15 may be constructed and arranged to adjust a position of extension of one of the surgical tools 140, 140a-b in response to a displacement of the of the first joystick in the direction corresponding to a longitudinal axis of the joystick. The controller 1 15 may be constructed and arranged to adjust a velocity of movement of one of the surgical tools 140, 140a-b in response to a displacement of the first joystick in the direction corresponding to a longitudinal axis of the control stick.

A second joystick of the one or more joysticks 315, 320 may be configured to generate a fourth control signal. The controller 1 15 may be constructed and arranged to manipulate (e.g., advance or retract, steer, actuate) another of the one of the surgical tools 140, 140a-b in response to the fourth control signal.

In some embodiments, displacement of the joystick 315, 320 in any one of the X, Y or Z directions can optionally control displacement, velocity or acceleration movements of a surgical tool 140, 140a-b. For example, displacing one of the joysticks 315, 320 by a first distance in anyone of the X, Y or Z directions may command and/or control a surgical tool 140, 140a-b of the system 100 to be displaced by the first distance (or a multiple thereof) in a corresponding direction (displacement control). In another example, displacing one of the joysticks 315, 320 by a first distance in anyone of the X, Y or Z directions may command and/or control a surgical tool 140, 140a-b of the system 100 to move at a velocity

proportional to the first distance of displacement in a corresponding direction (velocity control). In another example, displacing one of the joysticks 315, 320 by a first distance in anyone of the X, Y or Z directions may command and/or control a surgical tool 140, 140a-b of the system 100 to accelerate proportional to the first distance of displacement in a corresponding direction (acceleration control).

Alternatively or additionally, velocity or acceleration of the joystick 315, 320 in anyone of the X, Y or Z directions can optionally control displacement, velocity or acceleration of a surgical tool 140, 140a-b. For example, moving one of the joysticks 315, 320 at a first speed in anyone of the X, Y or Z directions may command and/or control a surgical tool 140, 140a-b of the system 100 to move at a speed proportional to the first speed in a corresponding direction. In another example, moving one of the joysticks 315, 320 at a first speed in anyone of the X, Y or Z directions may command and/or control a surgical tool 140, 140a-b of the system 100 to be displaced by a distance proportional to the first speed in a corresponding direction. Alternatively or additionally, a magnitude of force exerted on a joystick 315, 320 in anyone of the X, Y or Z directions can optionally control displacement, velocity or acceleration of a surgical tool 140, 140a-b. In addition, one or more of the buttons (of the sets of buttons 325, 330) of the hand-operated control device 21 1 can be configured to toggle between control modes, such as, a displacement control mode, a velocity control mode and an acceleration control mode.

Similarly, other outputs of the HID 210 or input signals of the surgical tool(s) 140, 140a-b and/or the articulating probe 120 can be controlled according to one or more of the above modes of operation. For example, a force exerted by surgical tool 140, 140a-b (e.g. grasper to pull hard on tissue) can be mapped to a force exerted on the hand-operated control device 21 1 or one of the joysticks 315, 320.

In addition, the HID 210 may be constructed and arranged to provide tactile feedback to a user. For example, the hand-operated control device 211 and/or one or more of the joysticks 315, 320 may be configured to provide mechanical stimulation to assist a user in visualizing movements of the articulating probe 120 and/or surgical tools 140, 140a-b within a patient's body or other type of cavity. The hand-operated control device 21 1 my include a button 310, such as a push button or force sensing resistor button, which may be configured to generate one or more control signals for actuating a functional element 141 , 141 a-b of one of the surgical tools 140, 140a-b.

The hand-operated control device 21 1 may include a vibration transducer 335 that may be configured to provide haptic or tactile feedback to an operator gripping or holding the hand-operated control device 21 1. For example, the vibration transducer 335 may provide haptic or tactile feedback to an operator gripping or holding the hand-operated control device 21 1 so as to notify the operator when an outer surface and/or the distal end 135 of the articulating probe 120 comes into contact with an inner cavity or lumen wall of a patient. Additionally or alternatively, tactile, vibrational, force or other feedback can be use to alert the operator of one or more system states such as an alarm or warning state.

The hand-operated control device may include one or more sets of buttons or switches 325, 330. For example, the hand-operated control device may include a first set of buttons or switches 325 and a second set of buttons or switches 330. In some embodiments, a first button of the first or second sets of buttons 325, 330 may be configured to map directional movements of a first joystick of the one or more joysticks 315, 320 to electromechanical movements of one of the surgical tools 140, 140a-b. A second button of the first or second sets of buttons 325, 330 may be configured to actuate a functional element of one of the surgical tools 140, 140a-b.

The hand-operated control device 21 1 may include a mode selection switch or button

345, which may be configured to change the control mode of a joystick. In a first control mode, directional movements of a first joystick of the one or more joysticks 315, 320 of the hand-operated control device 21 1 map to electromechanical movements of one of the surgical tools 140, 140a-b. In a second control mode, directional movements of the first joystick of the one or more joysticks 315, 320 of the hand-operated control device 21 1 map to

electromechanical movements of the articulating probe 120. An operator may toggle between the first and second modes by actuating the mode selection switch or button 345. Additional control modes may be included such as to control an additional tube, or to control articulating probe 120 and/or surgical tools 140, 140a-b in a different manner.

The hand-operated control device 21 1 may include a display device 340. The display device 340 may include one selected from the group consisting of a liquid crystal display, a CRT, an organic light-emitting diode display, a light-emitting diode display, an electronic ink display and an electrophoretic display. The display device 340 may be configured to display an image captured by a camera 160 of the articulating probe 120. The display device 340 may be configured to prompt a user of the system 100 with one or more steps of a medical procedure.

FIGs. 6A-6C are perspective views of hand operated control devices. The hand- operated control device 21 1 may include a lever 305 that is configured to actuate a functional element 141 of a surgical tool 140. For example, a first end of an actuating cable 1 18 may be coupled to the lever 305 and a second end of the actuating cable 1 18 may be coupled to a functional element 141 of the surgical tool 140. The actuating cable 1 18 may extend from the hand-operated control device 21 1 to the distal end of the surgical tool 140, 140a-b, and may be positioned within elements of the system 100 via one or more posts or capstans 307 (see FIG. 4). In some embodiments, the second end of the actuating cable 1 18 may be coupled to mechanical linkage 143 of the functional element 141.

The lever 305 may be constructed and arranged to apply a first tension tl to the actuating cable 1 18. The functional element 141 may be actuated in response to the first tension tl applied to the actuating cable 1 18. For example, an operator holding or gripping the hand-operated control device 21 1 may apply a force 306, such as a lateral force, to the lever 305 to apply the first tension tl to the actuating cable 118.

The hand-operated control device may further include an actuator 350, such as a linear actuator or solenoid. The actuator 350 may be constructed and arranged to apply a second tension t2 to the actuating cable 1 18 in response to an actuating control signal. The hand-operated control device 21 1 may include a button 310, such as a push button or force sensing button that may generate the actuating control signal. The actuating control signal may be transmitted from the button 310 to the actuator 350 via a wire or cable 31 1. In embodiments including a force sensing button, a magnitude of the second tension t2 applied to the actuating cable 1 18 may be proportional to an actuating force fl applied to the button 310.

In the embodiment illustrated at FIGs. 6A-6C, a slidable slug of the actuator 350 advances in an outward direction so as to push a portion of the actuating cable 1 18 between first and second posts 3Q6a-b. This movement causes the second tension t2 to be applied to actuating cable 1 18.

The hand-operated control device may further include a stop 355, which may be constructed and arranged to limit movement of the lever 305.

FIG. 7 is a perspective view of the human interface device shown in FIGs. 1, 2, 4, 5A and 5B. The HID 210 may include a hand-operated control device 211, a control stick 216 and a base 212. The hand-operated control device 211 may be coupled to a proximal end 214 of the control stick 216, and the base 212 may be moveably coupled or slidably coupled to a distal end 215 of the control stick 216.

The hand-operated control device 21 1 may be movable with respect to the base 212. For example, the hand-operated control device 21 1 may be moveable with respect to the base 212 in at least one or more of the directions selected from the group consisting of: the X direction, the Y direction, the Z direction and the Θ direction.

Movements of the hand-operated control device 21 1 with respect to the base 212 may generate control signals for manipulating the articulating probe 120 of the system 100. For example, a movement of the hand-operated control device 21 1 with respect to the base 212 in the X direction may manipulate and/or steer the articulating probe 120 in a second direction D2 (see for example, the second direction D2 illustrated in FIG 4). A movement of the hand- operated control device 21 1 with respect to the base 212 in the Y direction may manipulate and/or steer the articulating probe 120 in a third direction D3 (see for example, the third direction D3 illustrated in FIG 4). A movement of the hand-operated control device 21 1 with respect to the base 212 in the Z direction may manipulate and/or advance or retract the articulating probe 120 in a first direction Dl (see for example, the first direction Dl illustrated in FIG 4).

For example, the hand-operated control device 21 1 may be movable with respect to the base 212 in a direction corresponding to a longitudinal axis of the control stick 216. The direction corresponding to the longitudinal axis of the control stick 216 may correspond to the Z direction. The HID 210 may be configured to generate the first control signal in response to a movement of the hand-operated control device 211 in the direction

corresponding to the longitudinal axis of the control stick 216. As described above, the controller 1 15 of the system 100 may be constructed and arranged to manipulate the articulating probe 120 in response to the first control signal.

In some embodiments, the controller 1 15 may be constructed and arranged to adjust a position of extension of the articulating probe 120 in response to a displacement of the of the hand-operated control device 21 1 in the direction corresponding to the longitudinal axis of the control stick 216. The controller 115 may be constructed and arranged to adjust a velocity of movement of the articulating probe 120 in response to a displacement of the of the hand-operated control device 211 in the direction corresponding to the longitudinal axis of the control stick 216.

The hand-operated control device 21 1 may be movable with respect to the base 212 in a direction transverse to a longitudinal axis of the control stick 216. The direction transverse to a longitudinal axis of the control stick 216 may correspond to the X direction and/or the Y direction. In some embodiments, the hand-operated control device can be coupled to the base at a ball and socket joint 213, including ball 213a and socket 213b. The HID 210 may be configured to generate the first control signal in response to a movement of the hand-operated control device in the direction transverse to the longitudinal axis of the control stick 216. As described above, the controller 1 15 of the system 100 may be constructed and arranged to manipulate the articulating probe 120 in response to the first control signal.

FIGs. 8A and 8B are sectional views of an electrically activated surgical tool. A functional element 141 may be coupled to a distal end of the tool shaft of the surgical tool 140. The surgical tool 140 may include an actuator 142, which may be coupled to or connected to the functional element 141 via mechanical linkage 143.

The functional element 141 may be activated in response to a control signal generated by the HID 210. The actuator 142 of the surgical tool 140 may apply a force to the mechanical linkage 143 in response to the control signal, which may cause first and second claw members or grasper members of the functional element 141 to open and close. The control signal may be an electrical signal, which may be transmitted from the HID 210 to at least one of the controller 1 15 and the surgical tool 140 via a conductive wire 311.

FIGs. 9 A and 9B are sectional views of a mechanically activated surgical tool. A functional element 141 may be coupled to a distal end of the tool shaft of the surgical tool 140. The surgical tool 140 may include an actuating cable 1 18, which may be coupled to or connected to the functional element 141 via mechanical linkage 143.

The functional element 141 may be activated in response to a control signal generated by the HID 210. The control signal may be a mechanical signal, which may be transferred from the HID 210 to the mechanical linkage 143 via the actuating cable 1 18. The actuating cable 1 18 may apply a force to the mechanical linkage 143, which may cause first and second claw members or grasper members of the functional element 141 to open and close.

The actuating cable 118 may be further coupled to or connected to a lever 305 of the HID 210. In this manner, a resistance applied to the claw members or grasper members of the functional element 141 may be transferred from the functional element 141 to the lever 305. As such, an operator applying a force to the lever 305 may receive tactile feedback.

FIG. 10 is a perspective view of a console system. A console system 200 may include a HID 405, a monitor 205, a GUI 215 and an input device or cluster of input devices 440. The HID 405 may include first and second multi-axis input devices 420, 430, and an input device 410. The first and second multi-axis input device 420, 430 may include one or more features of the multi-function interface described in U.S. Patent No. 7,41 1 ,576, issued August 12, 2008, the contents of which is incorporated herein by reference in its entirety.

Each of the first and second multi-axis input devices 420, 430 may include a stylus

425, 435 coupled to an arm of the first and second multi-axis devices 420, 430. The input device 410 may include a displacement member 41 1 having a proximal and distal ends. A proximal end of the displacement member 41 1 may be coupled to a ball joint 410a and a distal end of the displacement member 41 1 may be coupled to a linking member 412.

Alternatively or additionally, a universal joint may be used to couple proximal and distal ends of displacement member 41 1.

The linking member 412 is constructed and arranged to removably couple the first and second styli 425, 435 together. For example, the first stylus 425 may be removably coupled to a first opening of the linking member 412 and the second stylus 435 may be removably coupled to a second opening of the linking member 412.

The HID 405 may be configured to generate the first control signal when a first user interface, such as the first stylus 425 of the first multi-axis input device 420 and a second user interface, such as the second stylus 435 of the second multi-axis input device 430 are coupled together (e.g., via the linking member). As described above, the controller 1 15 may be constructed and arranged to manipulate (e.g., advance or retract, steer, actuate) the articulating probe 120 in response to the first control signal. For example, the HID 405 may be configured to generate the first control signal when the first user interface of the first multi-axis input device and the second user interface of the second multi-axis input device are synchronously moved while attached to the ends of the linking member 412.

For example, when the first and second user interfaces are coupled, movements of the linking member 412 with respect to the input device 410 may generate control signals for manipulating the articulating probe 120 of the system 100. For example, a movement of the linking member 412 with respect to the input device 410 in Z direction may manipulate and/or advance or retract the articulating probe 120 in a first direction Dl (see for example, the first direction Dl illustrated in FIG 4). A movement of the linking member 412 with respect to the input device 410 in the X direction may manipulate and/or steer the articulating probe 120 in a second direction D2 (see for example, the second direction D2 illustrated in FIG 4). A movement of the linking member 412 with respect to the input device 410 in the Y direction may manipulate and/or steer the articulating probe 120 in a third direction D3 (see for example, the third direction D3 illustrated in FIG 4).

The HID 405 may be further configured to generate the second control signal when the first user interface of the first multi-axis input device 420 and the second user interface of the second multi-axis input device 430 are decoupled. As described above, the controller 1 15 may be constructed and arranged to manipulate (e.g., advance or retract, steer, actuate) one of the surgical tools 140, 140a-b in response to the second control signal. For example, the HID 405 may be configured to generate the second control signal when the first user interface of the first multi-axis input device 420 and the second user interface of the second multi-axis input device 430 are independently moved.

The console 200 may further include one or more foot pedals 450, which may be configured to generate a control signal. The control signal generated by the one or more foot pedals 450 may be transmitted to the controller 1 15 and/or the surgical tools 140, 140a-b. A functional element 141, 141 a-b of one of the surgical tools 140, 140a-b may be activated in response to the control signal generated by the one or more foot pedals 450.

At the option of the user, the signals generated by the HID 405 and the foot pedals 450 may be reconfigured. For example, the foot pedal 450 may be configured to generate a third control signal where the third control signal may be transmitted to the controller 115 and/or the probe 120.

FIG. 11 is a perspective view of a surgical tool. A surgical tool 500 may include a functional element 516 at distal end of a tool shaft 515. The functional element 516 may include one of the functional elements 141 described above. A proximal end of the tool shaft 515 may be coupled to or connected to a hand-operated lever 505, which may be constructed and arranged to actuate the functional element 516. The hand-operated lever 505 may include first and second hand grips 506, 507, which move relative to one another about an axis 508.

The surgical tool 500 may further include a joystick 510. The joystick 510 may be integral with the hand operated lever 505; however, in other embodiments the joystick 510 may be coupled to or connected to the hand operated lever 505. For example, in some embodiments, the joystick 510 is removably coupled to the second surgical tool, such as by way of a mechanical snap fit, clip, thumbscrew or magnetic fastening elements. In some embodiments, the joystick 510 is affixed to the hand operated lever 505 of the surgical tool 500 with an adhesive or other non-removable fastening element. The joystick 510 may be configured to generate a control signal, which may be transmitted (via a conductive wire or cable 520) to the console 200 and/or the controller 115 of the systems 100 described above. However, the control signal may be wirelessly transmitted to the console 200 and/or the controller 1 15. In this manner, an operator, such as a surgeon or medical professional, can command the systems 200 to manipulate the articulating probe 120 from a signal interfacing device.

While the present inventive concepts have been particularly shown and described above with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art, that various changes in form and detail can be made without departing from the spirit and scope of the present inventive concepts described and defined by the following claims.
