Problems solved by technology

[0003] Currently, the flexible biliary mirror commonly used in surgical operations is long and soft, which is very inconvenient for gallbladder stone removal. Cholesterol crystals and pseudopolyps attached to the gallbladder wall cannot be treated.
At present, there is still a lack of hard mirrors for gallstone preservation in clinical practice, and hard mirrors for other purposes cannot be directly used for gallstone preservation surgery

Embodiment 1

[0022] like figure 1 and figure 2 As shown, the hard mirror gallbladder-preserving stone removal sheath includes a strip-shaped main catheter 1 and a diaphragm 2 arranged in the main catheter 1. channel, and the main conduit 1 and the diaphragm 2 are integrally formed with pure silicone or PVC soft material. The three sub-channels are the hard mirror channel 3, the operating channel 4 and the water inlet channel 5. The aperture of the hard mirror channel 3 is larger than the apertures of the operation channel 4 and the water inlet channel 5 .

[0023] One port of the main conduit 1 is the common port 11 at the same side of all sub-channels, and the other port of the main conduit 1 is the hard mirror insertion port 31 of the hard mirror channel 3. The hard mirror insertion port 31 is trumpet-shaped, and the operation channel 4 and Another port of the water inlet passage 5 is arranged on the outer wall 12 of the main conduit 1 .

[0024] An operation conduit 6 is arranged o...

Embodiment 2

[0028] The content of embodiment 2 is basically the same as that of embodiment 1, the difference is that in this embodiment, a 310mm×5mm intracavitary hard mirror is used in conjunction with this hard mirror’s gallstone-preserving sheath, and the length of the main catheter 1 is harder than the 310mm×5mm intracavitary hard mirror. The length of the mirror is 10mm long, which is 320mm. The outer diameter of the main conduit 1 is 10mm. The aperture of the hard mirror channel 3 is 5.4mm. 8 is 200mm long. The rest of the same parts are no longer repeated.

Abstract

The invention relates to a hard choledochoscope gallbladder-protecting gallstone-taking sheath which solves the problems that the operation is very inconvenient when the prior biliary tract soft choledochoscaope is in gallbladder-protecting gallstone-taking operation and the hard choledochoscaopes with other purposes can not be directly used in the gallbladder-protecting gallstone-taking operation when being lack of the hard choledochoscaope. The hard choledochoscope gallbladder-protecting gallstone-taking sheath comprises a strip main catheter and diaphragms arranged in the main catheter, wherein the main catheter is divided into a plurality of branch channels axially arranged along the main catheter by the diaphragms, and the main catheter and the diaphragms are made of soft materials. The hard choledochoscope gallbladder-protecting gallstone-taking sheath is convenient for matching relatively hard choledochoscaopes, meets the clinical requirement of the biliary tract touchup surgery, achieves the purpose of facilitating the biliary tract operation, has little damage and less complicating disease to the patient in the biliary tract operation, and can be used as a pulling spade for pushing and spading cholesterol crystal attached on the gallbladder wall and small gallstones.

Description

【Technical field】 [0001] The invention belongs to the technical field of medical devices, and relates to an auxiliary device for surgical biliary rigid mirrors, in particular to a rigid mirror gallbladder-preserving and stone-removing sheath. 【Background technique】 [0002] The minimally invasive method of "preserving the gallbladder and removing stones and removing polyps" is currently the least traumatic method for the treatment of gallstones and gall polyps. It not only eliminates gallbladder diseases, but also protects the gallbladder and does not damage the physiological functions of the gallbladder. [0003] Currently, flexible biliary mirrors are commonly used in surgical operations. The mirrors are long and soft, which is very inconvenient for gallbladder stone removal. Cholesterol crystals and pseudopolyps attached to the gallbladder wall cannot be treated. At present, there is still a lack of hard mirrors dedicated to gallstone removal in clinical practice, and har...
