Abstract

The invention relates to a gallbladder and bile duct calculus remover, which comprises a spring outer tube, a resin conduit, an operating handle and a calculus removing device. The calculus remover is characterized in that: a pull rod is arranged inside the resin conduit; the handle rod of the operating handle is of a hollow structure with one sealed end and one opened end, a moving groove is opened on the handle rod, and a movement control ring, which can move forwards and backwards along the moving groove and can drive the pull rod to move forwards and backwards, is arranged on the handle rod; and the calculus removing device is composed of a slide block, a fixing seat and a sleeve net connected between the slide block and the fixing seat, the sleeve net is composed of multiple fine steel wire ropes which are uniformly arranged around the pull rod, and the opening and closing of the sleeve net are realized by fore-and-after movement of the pull rod. By calculus remover provided by the invention, the defects of the existing calculus removing operation are solved; and the calculus remover has the characteristics of agility in movement, good operation effect, simpleness in design, simpleness and convenience in 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...
