Abstract

The invention discloses a memory metal calculus extractor with illumination, which comprises an operating handle, a catheter and a calculus extracting device, wherein the calculus extractor also comprises a monitoring device formed by a camera, a guide line, a switch and a socket and an illuminating device formed by a light source, a guide line, a switch and a socket; the catheter is formed by an outer resin tube and an inner resin tube; the switches and the sockets are used for controlling the work of the light source and the camera; the camera and the light source are connected to the sockets and the switches through the guide lines passing through the outer resin tube; the calculus extracting device is formed by a fixed block, a fixed seat and a sleeve net connected between the fixed block and the fixed seat; and the sleeve net is formed by a plurality of thin memory metals evenly arranged surrounding the catheters. The calculus extractor solves the defects of the existing calculus extracting operation, is a surgical instrument using the character of deforming of the memory metal at the specific temperature to extract calculus, and has the characteristics of simple design, convenience for control, safety and reliability, good operation effect and the like.

Description

1. Technical field [0001] The invention relates to an operation instrument for removing calculi, in particular to an illuminating stone-removing instrument 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 ar...
