A gallbladder stone removal device
By using a biodegradable braided filament interwoven mesh-like stent combined with extracorporeal negative pressure suction, gallbladder stones can be removed efficiently and minimally invasively. This solves the problems of gallbladder damage and incomplete stone removal caused by existing devices. The stent degrades in the body without the need for a second surgery.

AI Technical Summary
Existing gallbladder stone removal devices have problems such as causing damage to the gallbladder, requiring multiple operations, and difficulty in removing small stone fragments. Furthermore, traditional methods may lead to gallbladder infection and inflammation.
A mesh-like stent made of biodegradable braided filaments is designed. The distal end of the stent forms a funnel or crown shape in the gallbladder, and the proximal end forms a straight tube or crown shape in the common bile duct or duodenum. Combined with an external negative pressure suction device, the stones can be removed in one procedure. The stent material degrades in the body without the need for a second surgery.
It achieves efficient and minimally invasive removal of gallstones, avoiding damage to the gallbladder and bile ducts, reducing surgical costs and the risk of complications. The stent degrades in the body, avoiding the need for a second surgery.
