Description

Technical Field

[0001] This utility model relates to a cholangioscopic stone removal isolation and drainage device via a sinus tract, specifically a device in which an adhesive layer is recessed from the upper side to the lower side to form a notch, allowing the adhesive layer to be applied only after the cholangioscopic endoscope is inserted, and the water outlet is fixed by a bent folded surface and a flexible fastener, which allows for changes in the accommodating space and the size of its opening. Background Technology

[0002] Choledochoscopic stone removal via the sinus tract is a common treatment for bile duct stones. When the choledochoscope is inserted into the bile duct through the sinus tract, a large amount of saline solution is injected to flush the bile duct before the stone is removed, ensuring that the imaging device on the choledochoscope can obtain a clear image. After the procedure, when the choledochoscope is removed from the sinus tract, a large amount of saline solution mixed with fine sand and gravel injected into the bile duct will be discharged from the sinus tract, contaminating the patient's wound, clothing, and operating table. It also causes water accumulation on the operating table, affecting subsequent aseptic cleaning.

[0003] To avoid contamination caused by the discharge of fine sand and gravel mixed with saline solution after choledochoscopy, a drainage device is installed at the sinus tract to drain the contaminants. Examples of drainage devices used in choledochoscopy include Chinese Utility Model Patent No. CN206045050U "An Isolation and Drainage Device for Choledochoscopic Stone Removal via Sinus Tract", Chinese Utility Model Patent No. CN202179729U "External Drainage Bag for Choledochoscopic Surgery", and Chinese Utility Model Patent No. CN206792489U "Choledochoscopic Examination Film-Integrated Water Collection Bag".

[0004] In Chinese utility model patents CN206045050U and CN206792489U, round holes are cut into the adhesive layer to attach the drainage device near the sinus tract and facilitate the insertion of the cholangioscope. This requires attaching the drainage device before inserting the cholangioscope, restricting the direction and position of insertion. Furthermore, the adhesive layer is typically disposable and its attachment position cannot be changed. CN202179729U lacks a design for the cholangioscope to pass through, resulting in the drainage device being attached further away from the sinus tract to avoid the cholangioscope. Post-operatively, there is still a possibility of saline solution mixed with fine sand and gravel splashing out.

[0005] In Chinese utility model patents CN206045050U, CN202179729U, and CN206792489U, the guide bag or water outlet receiver does not have a mechanism for fixing the opening. Although CN202179729U sets rolled edges on both sides of the guide bag, the rolled edges do not have the function of fixing the opening size. Therefore, the guide bag or water outlet receiver cannot maintain its shape continuously to ensure that it can completely hold the water. Utility Model Content

[0006] Therefore, the purpose of this invention is to provide a transsinus choledochoscopy stone removal isolation and drainage device.

[0007] This utility model provides a transsinus choledochoscopy stone removal isolation and drainage device, comprising:

[0008] An adhesive layer has an upper side and a lower side, and the adhesive layer has a notch formed by an indentation from the upper side to the lower side. A water outlet container is attached to the adhesive layer, and the water outlet container has a receiving space with an opening facing the upper side of the adhesive layer. A filter screen is detachably covered by the opening of the receiving space, and the filter screen is positioned below the notch in the adhesive layer. A drain tube connects to the receiving space of the water outlet container.

[0009] Furthermore, the water outlet container includes a front surface and two side surfaces located on opposite sides of the front surface, and a fitting portion is formed at the periphery of the front surface and the two side surfaces. The water outlet container is attached to the adhesive layer through the fitting portion, and the adhesive layer, the front surface, and the two side surfaces surround and form the receiving space. The side surfaces are divided into two folded surfaces by a fold line, and the two folded surfaces can be bent along the fold line. Preferably, a flexible fastener extends and is disposed on the two folded surfaces of the side surfaces.

[0010] Furthermore, the bonding part can be bonded to the adhesive layer by high-frequency hot melting, or it can be bonded to the adhesive layer by applying waterproof adhesive.

[0011] Furthermore, the filter screen is detachably attached to the adhesive layer and the water outlet container via a double-sided adhesive layer.

[0012] Furthermore, the height of the opening in the accommodating space is higher than the bottom of the notch.

[0013] The following effects can be achieved based on the above technical features:

[0014] 1. The adhesive layer of the isolation and drainage device of this utility model has a notch formed by the upper side concave to the lower side, such as a U-shaped notch. After inserting the cholangioscope into the appropriate position of the human body, the most suitable attachment position is selected after avoiding the cholangioscope.

[0015] 2. The sides of the water outlet can be bent at different angles by two folding surfaces and fixed by flexible fasteners. The size of the accommodating space and its opening can be changed according to needs, or it can be easily stored by being completely folded by the two folding surfaces when not in use.

[0016] 3. The filter screen of the isolation and diversion device of this utility model is a large-area plastic film filter screen with fine pores, which can remove all the collected fine sand and gravel at once. Regardless of whether all the water in the water outlet container has been drained, all the collected stones can be drained. Moreover, the filter screen is extremely thin and can be folded along with the folding surface, making it easy to store and space-saving. Attached Figure Description

Detailed Implementation

[0026] Based on the above technical features, the main functions of the transsinus choledochoscopy stone removal isolation and drainage device of this utility model will be clearly presented in the following embodiments.

[0027] Please see Figure 1 , Figure 2 and Figure 3As shown, this utility model provides a cholangioscopic stone removal isolation and drainage device via sinus tract, including: an adhesive layer 1 with an upper side 11 and a lower side 12 opposite to each other. The adhesive layer 1 has a notch 13 formed by the inward indentation from the upper side 11 toward the lower side 12. In this embodiment, the notch 13 is made into a U-shaped notch. A water outlet receiver 2 is attached to the adhesive layer 1. In this embodiment, the water outlet receiver 2 includes a front surface 21 and two side surfaces 22 located on opposite sides of the front surface 21. A bonding portion 23 is formed around the front surface 21 and the two side surfaces 22. The water outlet receiver 2 is bonded to the adhesive layer 1 by means of high-frequency hot melting or coating with waterproof adhesive through the bonding portion 23. The adhesive layer 1, the front surface 21 and the two side surfaces 22 surround and form an accommodating space 24. The accommodating space 24 has an opening 241 facing the upper side edge 11 of the adhesive layer 1, and the height of the opening 241 of the accommodating space 24 is higher than the bottom of the notch 13. The side surface 22 is divided into two folded surfaces 222 by a fold line 221. The two folded surfaces 222 can be bent along the fold line 221. A flexible fastener 25 extends and is fixed to the two folded surfaces 222 of the side surface 22. A filter screen 3 is detachably attached to the opening 241 of the accommodating space 24, and the filter screen 3 is positioned below the notch 13 on the adhesive layer 1. In this embodiment, the filter screen 3 is detachably attached to the adhesive layer 1 and the water outlet container 2 via a double-sided adhesive layer, and completely covers the opening 241 of the accommodating space 24 over a large area. A drain pipe 4 connects to the accommodating space 24 of the water outlet container 2.

[0028] Please see Figure 4 As shown, when the isolation and drainage device is not in use, the side 22 of the water outlet container 2 can be completely folded along the fold line 221 by the two folding surfaces 222, thereby reducing the size of the isolation and drainage device and making it easy to store.

[0029] Please see Figure 5 , Figure 6 and Figure 7 As shown, during cholangioscopic lithotripsy, a cholangioscope 5 is first inserted into the body 7 through the sinus tract 6. Then, the notch 13 of the adhesive layer 1 is aligned with the position of the cholangioscope 5 and moved in and attached to the appropriate position of the body 7. The folded surface 222 of the second part of the drain container 2 is bent and opened along the fold line 221 or even fully unfolded and fixed by the flexible fastener 25, thereby adjusting the accommodating space 24 and its opening 241 to an appropriate size. Through the notch 13 of the adhesive layer 1, it is possible to insert the cholangioscope 5 first and then attach the adhesive layer 1 without interfering with the insertion direction and position of the cholangioscope 5, and the drain container 2 can be placed close to the sinus tract 6.

[0030] Please see Figure 8As shown, when the cholangioscope 5 is removed postoperatively, the infused saline solution 8 and fine sand 9 are discharged from the sinus tract 6. The saline solution 8 passes through the filter screen 3 into the receiving space 24 and can be further discharged through the drainage tube 4. The fine sand 9 remains on the filter screen 3. After the filter screen 3 is removed, the fine sand 9 can be collected directly. After the saline solution 8 and fine sand 9 are discharged from the sinus tract 6, they are filtered and separated by the filter screen 3. The fine sand 9 will not enter the receiving space 24. Therefore, regardless of whether all the saline solution 8 in the outlet container 2 has been discharged, the collected fine sand 9 can be drained.

[0031] Based on the above description of the embodiments, it should be fully understood that the operation, use and effects of this utility model are as follows. The above embodiments are only preferred embodiments of this utility model and should not be used to limit the patent scope of this utility model. That is, simple equivalent changes and modifications made according to the contents of this utility model specification are all within the scope of this utility model.
