Abstract

An air-controlled stone extraction device, which includes an operating handle, a catheter, and a stone extraction device, is characterized in that it also includes a monitoring device composed of a camera, wires, switches, and sockets, and a lighting device composed of light sources, wires, switches, and sockets; The catheter is composed of a resin outer tube and a resin inner tube; the switch and the socket are used to control the light source and the camera, and the camera and the light source are connected to the socket and the switch through a wire passing through the resin outer tube; the handle of the operating handle There is a trachea in communication with the resin inner tube, and there is a notch on the handle rod, and there is an air suction port in the notch to connect with the trachea; the stone removal device is composed of a fixed block, a fixed seat, and a The sleeve net is composed of several thin hollow resin tubes with double-wall structure evenly arranged around the catheter. The invention solves the shortcomings of the existing stone removal operation, and makes it have the characteristics of flexible movement, good operation effect, simple design, simple and convenient control, safety and reliability, and the like.

Description

1. Technical field [0001] The invention relates to a surgical instrument for removing stones, in particular to a stone removal tool for gallbladder and bile duct. 2. Background technology [0002] At present, in the minimally invasive surgical treatment of gallbladder and bile duct stones, there has been a lack of dedicated gallbladder and bile duct stone removal tools. In the actual operation, clinicians mainly rely on the stone retrieval basket to remove stones, but the stone retrieval mesh basket is easy to slip when taking stones, especially for small stones; when encountering larger stones, the stone retrieval mesh basket cannot be stretched Stone removal, especially when the stone is incarcerated in the gallbladder or bile duct, the stone retrieval basket cannot pass over the stone, which will lead to a long time for stone removal, or even failure. When stone removal using the stone extraction basket fails, traditional laparotomy instruments are used to remove gallbla...
