Stone removal device for gallbladder wall stones

Abstract

The invention relates to a stone removal device for gallbladder wall stones, comprising a mirror body and an outer sheath, the outer sheath is arranged at one end of the mirror body, and the mirror body is provided with a water inlet, a water outlet valve, an eyepiece and a light source; one end of the outer sheath is connected with a propelling Components, the propulsion component is composed of a telescopic frame body and an elastic cylindrical film sleeved outside the telescopic frame body, the other end of the propelling component is provided with a closing component, and the telescopic frame body and the closing component are driven by a driving component; the gallbladder wall stone of the present invention The stone removal device can confine the stones on the gallbladder wall in a closed space. When the stone crushing operation is performed in this closed space, the stone residue will not enter the body, and there will be no stone residue after the operation, and will not cause damage to the surrounding tissues. Calculus debris has little interference with the endoscopic field of view and has little impact on the operation process, which can significantly improve the operation efficiency and effect, and significantly reduce the pain and burden of patients.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a stone removal device for gallbladder wall stones. 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 technology used today is to cut the gallbladder and take out the stones, and then suture the gallbladder under laparoscope. Stones, and when larger stones are taken out after being bagged in the abdominal cavity, it is necessary to make an incision on the abdomi...

AI Technical Summary

Problems solved by technology

Laparoscopic-choledochoscopy combined with stone removal can achieve simultaneous lithotripsy. Larger stones can be crushed and taken out, and smaller stones can be taken out 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
