SELF-RETAINING DRAIN IN THE SALIVARY DUCT

Technical Field

The invention relates to a drain used in the salivary gland duct after sialendoscopy applied for salivary stone.

In particular, the invention relates to a drain that can be fixed seamlessly to the salivary gland canal and remain in the canal for the desired time and can be removed practically without damaging the salivary gland canal.

State of the Art

Drain is used in cases where surgical interventions are performed, tissue cavities are formed, or it is desired to leave an opening in the intervention of tissues with a canal system. The purpose of these drains is to create drainage and accelerate wound healing by removing pus, blood, inflammation, and similar fluids from the skin.

In the current art, the drains used after the intervention to the tissues where tissue gaps are formed or with a ducts system are traditionally made of materials such as silicone or rubber, rubber, and are in the form of pipes. These drains are fixed to the skin by suturing after being extended to the surgical area. Generally, pain and infection develop around this suture and sometimes the drain remains shorter than the desired time due to the early melting of the sutures.

After the sialendoscopy applied for salivary stone, a drain is left in the salivary gland ducts system and this drain should remain in the salivary gland duct for 3 weeks. However, silicone drains fixed by sutures in the mouth are released over time due to the digestion of the suture material with the enzymes in the mouth and the drain remains less than the desired time. For this reason, in the known state of the art, there was a need for a drain that adhered to the salivary gland duct without sutures for the desired time, especially after sialendoscopy. Patent Application No. US3823720 may be shown as an example of the state of the art as a result of the research conducted on the literature. Said document is directed to the field of medical equipment and provides surgical evacuation that can be placed in a body cavity or wound to evacuate naturally occurring fluid from the cavity. The invention discloses a surgical drain having a nylon mesh wrapped around its innermost end with a plurality of rather loose folds and held in place by a plurality of silk ties at points spaced along its length.

Another example of the state of the art is Patent Application No. CN101472630. The aforementioned document relates to the field of arthroscopic surgery and, more specifically, fluid management in shoulder arthroscopic surgery. A surgical portal plug used in shoulder surgery is described in said invention.

As a result, the presence of the above problems and the inadequacy of existing solutions made it necessary to make a development in the relevant technical field.

Object of the Invention

The present invention relates to a self-retaining drain in the salivary duct for eliminating the foregoing disadvantages and bringing novel advantages to the related technical field.

The main object of the invention is to provide a drain that is fixed seamlessly by holding on to the salivary gland duct by means of its tabs and can remain in the salivary gland duct for the desired period of time.

The object of the invention is to provide a drain that can be practically removed without damaging the salivary gland duct.

Another object of the invention is to provide a drain that is ensured to remain in the salivary gland duct for the desired time by eliminating the problem of the suture materials being affected by the enzymes in the mouth thanks to its seamless fixation to the salivary gland duct.

The invention is a drain used in the salivary gland duct after sialendoscopy applied to the salivary stone in order to fulfill all the objects that may arise from the above-mentioned and detailed description, and comprises the following elements:

- an outer part placed in the salivary gland duct and discharging the fluids in the salivary gland duct from the inner surface through at least one outer part drainage hole,

- an inner part that moves reciprocally within the outer part and discharges the fluids in the salivary gland duct outwardly from its inner surface by means of at least one inner part drainage hole disposed thereon,

- a flexible tab located on the outer surface of the inner part, which closes and opens with the forward movement of the inner part in the outer part and opens when it coincides with the tab slots on the outer part, comes out of the tab slots and attaches to the surface of the salivary gland duct, allowing the drain to be fixed to the salivary gland duct,

- a safety lock positioned between the inner part and the outer part and connected to the end of the inner part, which locks the inner part in the outer part when the drain is in the salivary gland duct and prevents the inner part from moving reciprocally in the outer part,

- a removal apparatus, which is moved forward within the inner part and by means of the forward movement of the inner part within the outer part, the tabs of the inner part enter the tab slots and close inwardly, allowing the drone to be removed from the salivary gland duct.

The structural and characteristic features and all the advantages of the invention will be understood more clearly by reference to the following figures and the detailed explanation thereof. Therefore, the evaluation should be made by taking these figures and detailed explanations into consideration.

Detailed Description of the Invention

In this detailed description, the preferred alternatives to the drain of the invention are described solely for the purpose of a better understanding of the subject matter and without any limiting effect.

Figure 1 shows the view of the disassembled state of the drain of the invention. Accordingly, in its most basic form, the drain comprises the outer part (10) placed in the salivary gland duct and discharging the fluids in the salivary gland duct from the inner surface, the safety lock (30) that moves back and forth in the outer part (10) and allows the drain to be fixed to the salivary gland duct by holding on to the surface of the salivary gland duct by means of the flexible tabs (22) on the outer surface of the outer part (10) and at the same time discharging the fluids in the salivary gland duct from the inner surface, the inner part (20) that is connected to the end of the inner part (20) and positioned between the inner part (20) and the outer part (10) and prevents the inner part (20) from moving back and forth in the outer part (20) by locking the outer part (10), the removal apparatus (40) that moves the inner part (20) forward in the inner part (20) and allows the inner part (20) to be removed from the salivary gland duct by closing the tabs (22) inwardly by the inner part (22) through the forward movement of the inner part (20) in the outer part (10).

The drain of the invention basically consists of two parts, the outer part (10) and the inner part (20). As seen in Figure 2, the inner part (20) is inserted into the outer part (10). The diameter of the inner part (20) is smaller than the outer part (10). The nested outer part (10) and the inner part (20) are placed in the salivary gland duct and allow the fluids in the salivary gland duct to drain out of the inner surface. Accordingly, there is at least one outer part drainage hole (11) on the outer part (10) and at least one inner part drainage hole (21) on the inner part (20). Flexible tabs (22) extending outwardly at an angle on the outer surface of the inner part (20) are formed so that the drain of the invention can be fixed to the salivary gland duct without seams. Accordingly, there are tab slots (12) on the outer part (10) that allow the tabs (22) to protrude from the outer part (10). When the inner part (20) is placed in the outer part (10), the tabs (22) are first bent inwards and closed and the inner part (20) is opened when it coincides with the tab slots (12) with the forward movement of the outer part (10) and comes out of the tab slots (12). Thus, the tabs (22) protruding from the tab slots (12) attach to the surface of the salivary gland duct and allow the drain to be fixed to the salivary gland duct.

While the drain is in the salivary gland duct, a safety lock (30) is connected to the end of the inner part (20) so that the inner part (20) stays between the inner part (20) and the outer part (10) in order to prevent the involuntary back and forth movement of the inner part (20) within the outer part (10). The safety lock (30) prevents the inner part (20) from moving back and forth in the outer part (20) by locking it in the outer part (10).

When it is necessary to remove the drain from the salivary gland duct, it is necessary to separate it from the surfaces where the tabs (22) are attached, which protrude from the tab slots (12) and attach to the surface of the salivary gland duct. For this, a removal apparatus (40) is placed in the inner part (20), which is moved forward. The removal apparatus (40) allows the inner part (20) to move forward within the outer part (10) and thus remove the drain from the salivary gland duct by closing the inner part (20) tabs (21) inwardly as shown in Figure 3.

THE USE OF THE DRAIN OF THE INVENTION IS AS FOLLOWS:

The inner part (20) is placed in the outer part (10) and the nested outer part (10), and the inner part (20) are positioned in the salivary gland duct. Meanwhile, the tabs (22) protruding from the tab slots (12) of the outer part (10) are attached to the surface of the salivary gland duct and the drain is fixed to the salivary gland duct. A safety lock (30) is attached to the end of the inner part (20) so that the inner part (20) stays between the inner part (20) and the outer part (10) in order to prevent the unintentional back and forth movement of the inner part (20) within the outer part (10). The drain of the invention remains unaffected by the enzymes in the mouth during the treatment period. During said period, fluids in the salivary gland duct are discharged out of the outer part drainage hole (11) and the inner part drainage hole (21) on the inner part (20).

In order to remove the drain from the salivary gland duct, the removal apparatus (40) is placed inside the inner part (20) and moved forward. With the forward movement of the inner part (20) within the outer part (10), the tabs (22) get rid of the tab slots (12) and close inwardly.

Thus, it is ensured that the tabs (22) are separated from the surface of the salivary gland duct to which they are attached. Then, the outer part (10) and the inner part (20) are pulled out of the salivary gland duct.
