Description

Technical Field

[0001] This utility model relates to a drainage device, and more particularly to a fully enclosed transsinus choledochoscopy stone removal isolation drainage device. Background Technology

[0002] Bile duct stones refer to the formation of stones in the biliary system, including stones in the intrahepatic bile ducts, common bile duct, and gallbladder. Stones in different locations can exist alone or in combination.

[0003] Gallstones located in the gallbladder or bile ducts are treated by using a choledochoscope inserted through the sinus tract to break up or remove the stones. During the procedure, saline solution is continuously injected to flush the bile ducts to obtain a clear image. The stones are broken into smaller fragments during the procedure. The saline solution will continue to flow out during the procedure and after the choledochoscope is removed, or it may flow out at the same time as the stone fragments are removed. If it is not collected, it will contaminate the surgical environment or the patient's body or clothing. The procedure will require cleaning and disinfection again after the operation. The procedure is quite complicated.

[0004] Therefore, to avoid the continuous leakage of saline solution during stone removal, which could soil the patient's body or clothing, or contaminate the surgical environment, a Chinese utility model patent announcement No. CN206045050U, entitled "An Isolation and Drainage Device for Stone Removal via Sinus Tract Choledochoscopy," is proposed. This device includes an adhesive layer, a choledochoscope probe, a water outlet container, an anti-clogging filter, a drainage tube, and a drain outlet. The choledochoscope probe is located at the midpoint of the upper 1 / 3 of the adhesive layer. The water outlet container is hollow in the middle and tightly fitted to the adhesive layer on all sides. The upper layer has a semi-circular opening and is positioned higher than the bile duct orifice. This design effectively solves the problem of severe saline leakage during choledochoscopy via the sinus tract, reducing the risk of blockage and significantly improving surgical quality and patient comfort.

[0005] However, the saline solution in the aforementioned case is still an open receiving space. When the stones are removed, the cholangioscope is also completely removed from the patient's body. At this time, when the saline solution flows out of the patient's body along with the stones, it may splash into the patient's or the surgical space. In addition, when the cholangioscope in the aforementioned case is removed from the patient's skin, it must be moved towards the opening of the receiving device, which makes it easier to interfere with the cholangioscope and increase the risk of contamination. Utility Model Content

[0006] Therefore, the purpose of this invention is to provide a fully enclosed transsinus cholangioscopic stone removal and drainage device that can collect saline solution splashed from any angle, and allows the cholangioscope to be inserted into or removed from the sinus tract at a suitable angle, such as perpendicular to the skin surface, to reduce the chance of contamination. Furthermore, the bag can be pre-expanded to provide a suitable accommodating space to hold the saline solution and stones flowing from the patient's body.

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

[0008] A bag body has an upper layer and a lower layer that are closed around its perimeter, forming an accommodating space. The upper layer has a first opening, and the lower layer has a second opening. Both the first and second openings communicate with the accommodating space, and the position of the first opening corresponds to the position of the second opening. An adhesive layer is disposed on the outer surface of the lower layer and surrounds the second opening. A support frame is disposed within the accommodating space, having a top surface and a bottom surface facing each other, and a connection point to the top surface. The support frame is attached to the upper layer via the top surface and one side of the bottom surface. The top surface has a top surface opening, the bottom surface has a bottom surface opening, and the side surface has at least one side surface opening. The top surface opening, the bottom surface opening, and the aforementioned side surface openings are connected to the receiving space. The top surface opening is connected to the first opening. The bottom surface can be selectively attached to the lower layer so that the bottom surface opening is connected to the second opening. A connector has a first end and a second end that are connected. The connector has a filter screen. The first end is disposed on the bag body and is connected to the receiving space.

[0009] Furthermore, the first opening is cross-shaped, and the second opening is circular.

[0010] Furthermore, the adhesive layer is ring-shaped, and has an adhesive portion and a release backing paper, which can be detachably attached to the adhesive portion.

[0011] Furthermore, at least one notch is provided at the periphery, and the notch is located between the connector and the second opening in a height direction.

[0012] Furthermore, the side surface includes at least one support portion, which is disposed adjacent to the aforementioned side surface opening.

[0013] Furthermore, the side surface includes a plurality of the aforementioned support portions and a plurality of the aforementioned side openings, with the aforementioned support portions and the aforementioned side openings being arranged alternately.

[0014] Furthermore, a conduit is connected to the second end.

[0015] Furthermore, when the bottom surface is not attached to the lower layer, the position of the support frame relative to the lower layer can be finely adjusted so that the position of the bottom surface opening can be eccentrically set relative to the position of the second opening.

[0016] Furthermore, the filter is located at the first end.

[0017] The following effects can be achieved based on the above technical features:

[0018] 1. It can collect saline solution and lithotripsy splashed from the sinus tract from any angle, avoiding contamination of the patient's clothing or the surgical space.

[0019] 2. The choledochoscope can enter or exit the sinus tract at an angle close to perpendicular to the patient's skin, improving the convenience of the surgical procedure.

[0020] 3. The support frame is pre-installed inside the bag. The support frame can open the bag to provide suitable storage space so that the saline solution and gravel flowing out of the patient's body can easily move towards the connector.

[0021] 4. When operating the cholangioscope inserted into the human body, the support frame can move slightly up and down or left and right in coordination with the cholangioscope, thereby allowing for smooth operation of the cholangioscope without being restricted by the support frame.

Detailed Implementation

[0031] Based on the above technical features, the main functions of the fully enclosed transsinus choledochoscopy stone removal isolation and drainage device of this utility model will be clearly presented in the following embodiments.

[0032] Please see Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a fully enclosed transsinus choledochoscopy stone removal isolation and drainage device, which includes a bag body 1, an adhesive layer 2, a support frame 3, a connector 4 and a catheter 5.

[0033] The bag body 1 has an upper layer 11 and a lower layer 12 that are closed along a perimeter 13. The upper layer 11 and the lower layer 12 surround each other to form an accommodating space 14. The upper layer 11 has a first opening 111, and the lower layer 12 has a second opening 121. The first opening 111 communicates with the accommodating space 14, and the second opening 121 communicates with the accommodating space 14. The position of the first opening 111 corresponds to the position of the second opening 121. Specifically, the upper layer 11 and the lower layer 12 are made of plastic, and they are joined together by high-frequency welding when closed along the perimeter 13. The first opening 111 is cross-shaped, and the second opening 121 is circular. Two notches 131 are disposed opposite to each other on the periphery 13. The two notches 131 are positioned in a height direction between the connector 4 and the second opening 121. The line connecting the two notches 131 forms a tear line. Specifically, in this embodiment, the optimal position of the two notches 131 is to be located at the middle position between the bottom edge of the adhesive layer 2 and the first end 41 of the connector 4, and to make the tear line perpendicular to the height direction. However, it is not limited to this. The tear line formed by the line connecting the two notches 131 can also be oblique and pass between the bottom edge of the adhesive layer 2 and the first end 41 of the connector 4, which is also a feasible implementation.

[0034] The adhesive layer 2 is disposed on the outer surface of the lower layer 12 and surrounds the second opening 121; specifically, the adhesive layer 2 is annular, and the adhesive layer 2 has an adhesive portion 21 and a release backing paper 22, and the release backing paper 22 is separably attached to the adhesive portion 21.

[0035] The support frame 3 is disposed in the accommodating space 14. The support frame 3 has a top surface 31 and a bottom surface 32 facing each other, and a side surface 33 connecting the top surface 31 and the bottom surface 32. The support frame 3 is attached to the upper layer 11 via the top surface 31. The top surface 31 has a top surface opening 311, the bottom surface 32 has a bottom surface opening 321, and the side surface 33 has at least one adjacent side surface opening 332 and at least one support portion 331. The top surface opening 311, the bottom surface opening 321, and the aforementioned side surface opening 332 are connected to the accommodating space 14. The opening 311 connects to the first opening 111, and the bottom surface 32 can be selectively attached to the lower layer 12, so that the bottom opening 321 connects to the second opening 121. In this embodiment, the support frame 3 has a hollow cylindrical shape. The side surface 33 includes a plurality of the aforementioned support parts 331 and a plurality of the aforementioned side openings 332. The aforementioned support parts 331 and the aforementioned side openings 332 are staggered. When the bottom surface 32 is not attached to the lower layer 12, the support frame 3 can make slight movements to cooperate with the movement of the cholangioscope, so as to avoid affecting the operation of the cholangioscope.

[0036] The connector 4 has a first end 41 and a second end 42 that are connected. The connector 4 is provided with a filter screen 411. The first end 41 is disposed on the bag body 1 and communicates with the accommodating space 14. The conduit 5 is connected to the second end 42. Specifically, in this embodiment, the filter screen 411 is disposed at the position of the first end 41, but it is not limited to this. It can also be disposed at the position of the second end 42, or disposed between the first end 41 and the second end 42. All of these are feasible implementation methods.

[0037] Please see Figure 3 and Figure 4 As shown, in use, the bag 1 is first adhered to the patient's skin via the adhesive layer 2, and the position of the second opening 121 is aligned with the location of the sinus tract on the patient's skin; specifically, the release backing paper 22 is separated from the adhesive part 21, so that the adhesive side of the adhesive part 21 is exposed and can be adhered to the patient's skin, without having to adhere the entire bag 1 to the skin, which can greatly reduce the discomfort caused by having to remove the adhesive from the skin.

[0038] Please see Figure 1 , Figure 5 and Figure 6As shown, after the bag body 1 is glued and fixed, the cholangioscope is inserted into the bag body 1 through the first opening 111, and then through the top opening 311 and the bottom opening 321 of the support frame 3, and out of the bag body 1 through the second opening 121 to enter the human body through the sinus tract on the patient's skin. In this embodiment, the support frame 3 is only fixed to the upper layer 11, and the support frame 3 is not attached to the lower layer 12. Therefore, when using the cholangioscope, the position of the bottom opening 321 of the support frame 3 can be offset relative to the position of the second opening 121, so that the support frame 3 can swing slightly up and down or left and right relative to the lower layer 12 to adjust the position of the support frame 3 in conjunction with the cholangioscope, thereby allowing for smooth operation of the cholangioscope without being restricted by the support frame 3.

[0039] Please see Figure 7 As shown, when the cholangioscope is to be removed, it is moved away from the body. After the cholangioscope is removed from the body, the previously injected saline solution and the stones in the patient's body will spray or seep out from the sinus. At this time, the fully enclosed bag 1 and the pre-set support frame 3 inside the bag 1 can first open the bag 1, so that the sprayed or seeping saline solution and the stones in the patient's body can be completely collected into the bag 1, and the saline solution can flow out of the bag 1 through the connector 4, while the stones in the patient's body can be blocked by the filter screen 411 and retained in the receiving space 14.

[0040] Please see Figure 8 As shown, after the surgery is completed, the bag 1 can be cut or torn open from the tear line formed between the two aforementioned gaps 131, and the gravel can be removed from the bag 1 for examination or for confirmation by the patient and their family.

[0041] 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 scope of implementation of this utility model. That is, any simple equivalent changes and modifications made based on the content of this utility model specification are within the scope of this utility model.
