Gallbladder calculus removing device with lockable calculus crushing end

Abstract

The invention relates to a gallbladder calculus removing device with a lockable calculus crushing end. The gallbladder calculus removing device with the lockable calculus crushing end comprises an outer lens sheath and a lens body, wherein a rotary sheath and an inner lens sheath are arranged in the outer lens sheath, the rotary sheath is rotatably sheathed outside the inner lens sheath, and an axial relative displacement cannot be produced between the rotary sheath and the inner lens sheath; a calculus picking-up assembly is arranged at one end, far away from the lens body, of the inner lens sheath, one opening is also formed in the side wall of the calculus picking-up assembly, the opening can be covered by a sealing assembly, an instrument channel pipe is arranged in a cavity of the inner lens sheath, a calculus crushing assembly is arranged in the instrument channel pipe, and the calculus crushing end of the calculus crushing assembly is inserted into the calculus picking-up assembly. According to the gallbladder calculus removing with the lockable calculus crushing end, a calculus can be placed in an enclosed space and is crushed, no calculus residue is produced, little damage is caused to surrounding tissues, interference of calculus chips to view of an endoscope is small, operation efficiency and an operation result can be obviously improved, and pain and burden of a patient can be alleviated.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a gallbladder stone extraction device with a sealable stone crushing end. Background technique [0002] The incidence of gallbladder stones is relatively high, and the main treatment method is: small gallbladder stones are treated with oral stone-discharging drugs, and for large or multiple gallbladder stones, surgical gallbladder removal is an indication, but with the development of surgical techniques, The technique of laparoscopic or laparoscopic choledochoscopy combined with gallstone preservation has become the development direction of gallbladder stone treatment. [0003] The gastrointestinal gallbladder-preserving stone removal technique used today is to cut the gallbladder open and take out the stones, and then suture the gallbladder underground in the abdominal cavity. , and when larger stones are taken out after being bagged in the abdominal cavity, it is n...

AI Technical Summary

Problems solved by technology

Laparoscopic-choledochoscopy combined with stone removal can achieve simultaneous lithotripsy and removal of stones. Larger stones can be removed after crushing, and smaller stones can be removed directly. During stone extraction, stone fragments are very likely to enter the cystic duct or common bile duct, causing residual stones, secondary bile duct stones to cause biliary obstruction, and laser or ultrasound can cause certain damage to the gallbladder wall and surrounding tissues. Complications such as gallbladder perforation

In addition, the interference of gallbladder debris on the vision of the gallbladder lens can also affect the efficiency of the operation, prolong the operation time, increase the risk of the operation, and increase the pain and burden of the patient
