Description

Technical Field

[0001] The utility model relates to the technical field of ERCP treatment of digestive endoscopes, and more specifically to a multifunctional adapter for a duodenoscope. Background Art

[0002] Endoscopic retrograde cholangiopancreatography (ERCP) is a technique that uses a combination of endoscopy and X-ray technology to diagnose and treat certain problems with the bile duct or pancreatic duct system. Through the endoscope, the doctor can see the inside of the stomach and duodenum and inject contrast agents into the ducts of the bile duct and pancreas so that they can be seen on X-rays. Currently, ERCP technology is relatively mature, but we need to use an adapter when using an endoscope.

[0003] In the medical field, the adapter is also called a forceps pipeline opening valve, which is made of rubber. During use, the traditional adapter only controls the liquid overflow through the small rubber hole. From the current point of view, the effect is not good. Some designs are to hang a collection bag on the adapter to collect the liquid. The operation is cumbersome and the effect is not ideal. In addition, the traditional adapter cannot fix the guide wire and needs to be fixed by hand, which is inconvenient and easily causes hand fatigue. Therefore, the utility model provides a multi-functional adapter for duodenoscope. Utility Model Content

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] Example

[0024] like Figure 1-3 As shown, the multifunctional adapter for duodenoscope comprises an adapter housing 1 and a fixed cassette accessory 5, the outer circumferential surface of the adapter housing 1 is fixedly connected with a negative pressure suction connection port 2, the inner wall of the adapter housing 1 is fixedly connected with a first rubber barrier layer 3, a through hole 1 31 is provided on the first rubber barrier layer 3, a second rubber barrier layer 4 is embedded at the upper end of the adapter housing 1, a through hole 2 41 is provided on the second rubber barrier layer 4, a crack 42 is provided on the inner wall of the through hole 2 41, a cavity 11 exists between the first rubber barrier layer 3 and the second rubber barrier layer 4, and the cavity 11 is connected with the negative pressure suction connection port 2;

[0025] The fixed card strap accessory 5 is provided with a first card slot 51 and a second card slot 52 , and the fixed card strap accessory 5 is also provided with an L-shaped card slot 53 .

[0026] When in use, the first rubber barrier layer 3 has a through hole 1 31 built in, which allows the guide wire to pass through tightly and minimizes liquid spillage. The second rubber barrier layer 4 is similar to a lid that can be lifted up, and has a through hole 2 41 built in, and a crack 42 is opened on its inner wall. After the guide wire passes through the through hole 2 41, the crack 42 can clamp and fix the guide wire. There is a cavity 11 between the two rubber barrier layers, which allows the liquid overflowing from the through hole 1 31 to gather there, and is connected to the negative pressure device through the negative pressure suction connection port 2 on the side wall to be sucked away. The operation is simple and the suction effect on the liquid is good. In addition, a fixed cassette accessory 5 is added to additionally fix the guide wire to reduce muscle fatigue caused by manual fixation;

[0027] When the fixed card belt accessory 5 is wrapped around the mirror body, it is clamped and fixed by the card slot 1 51 and the card slot 2 52, and the L-shaped card slot 53 is used to clamp the guide wire.

[0028] like Figure 1-2 As shown, the second rubber barrier layer 4 is designed to be thickened.

[0029] When in use, by thickening the second rubber barrier layer 4, the crack 42 thereof is also deeper, which can increase the contact area between the crack 42 and the fixed guide wire, thereby improving the fixing effect of the guide wire.

[0030] like Figure 1-2 As shown, the outer diameter of the second rubber barrier layer 4 is greater than the outer diameter of the adapter housing 1 .

[0031] When in use, it is convenient for personnel to lift up the second rubber barrier layer 4.

[0032] like Figure 1-2 As shown, the diameter of the through hole 1 31 is 0.5 mm, and the diameter of the through hole 2 41 is 1 mm.

[0033] When in use, the diameter of the guide wire is generally 0.6mm-0.9mm. The through hole 1 31 with a diameter of 0.5mm can ensure that the guide wire can pass through tightly, and the through hole 2 41 with a diameter of 1mm facilitates the guide wire to pass through the hole quickly.

[0034] like Figure 1-2 As shown, a flexible connecting belt 12 is fixedly connected to the outer circumferential surface of the adapter housing 1 , and one end of the flexible connecting belt 12 is fixed to the second rubber barrier layer 4 .

[0035] When in use, the possibility of the second rubber barrier layer 4 falling off and being lost can be reduced under the connection of the flexible connecting belt 12 .

[0036] In summary, the specific working process of this scheme is as follows: the traditional adapter is heightened and two rubber barrier layers are set up inside it. The first rubber barrier layer 3 has a through hole 1 31 built in it, which allows the guide wire to pass through tightly and minimizes liquid overflow. The second rubber barrier layer 4 is similar to a lid that can be lifted up, and has a through hole 2 41 built in it, and a crack 42 is opened on its inner wall. After the through hole 2 41 is passed through by the guide wire, the crack 42 can clamp and fix the guide wire. There is a cavity 11 between the two rubber barrier layers, which allows the liquid overflowing from the through hole 1 31 to gather there, and is connected to the negative pressure device through the negative pressure suction connection port 2 on the side wall to be sucked away. The operation is simple and the liquid suction effect is good. In addition, a fixed cassette accessory 5 is added to additionally fix the guide wire to reduce muscle fatigue caused by manual fixation.

[0037] When the fixed card belt accessory 5 is wrapped around the mirror body, it is clamped and fixed by the card slot 1 51 and the card slot 2 52, and the L-shaped card slot 53 is used to clamp the guide wire.

[0038] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
