Remover for calculus of intrahepatic duct of hepatology

Abstract

The invention provides a remover for calculus of intrahepatic duct of hepatology. The remover comprises a rotation motor, a rotation shaft, a casing tube, a scraping net, and a collection bag. The rotation motor is connected with the rotation shaft; the rotation shaft is arranged in a rotation channel inside the casing tube; and the scraping net and the collection bag are arranged at the tail end of the rotation shaft, wherein the scraping net and the collection bag are disturbed in an ellipsoid shape. The scraping net is formed by a plurality of scraping knives distributed uniformly; and the coverage angel of the scraping net is one half of the ellipsoid. A plurality of micro holes are formed in the surface of the collection bag and the coverage angle of the collection bag is the other half of the ellipsoid. According to the invention, the remover with a simple structure can be used conveniently. With the rotation motor as well as the matched scraping net, collection bag, and the negative-pressure device, the calculus can be removed completely and effectively and the bile duct can be protected from being damaged. Meanwhile, when the calculus is removed, the blood attached to the calculus surface can be cleaned and the calculus and the blood clot can be separated.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a remover for hepatobiliary intrahepatic bile duct stones. Background technique [0002] Intrahepatic bile duct stones are one of the common diseases in the hepatobiliary department. The most effective way to treat intrahepatic bile duct stones is to remove the stones through surgery. The most commonly used stone removal tool in the operation is the stone removal forceps. During the stone removal process, use the stone removal forceps to clamp the stones Hold and remove. During the operation, due to the need to stretch the bile duct, it may cause damage to the bile duct, especially when the stone is large, and the damage may be more serious; after the stone is removed, it needs to be washed with blood cleaning solution, and then brain surgery Film is used to collect calculus, but in this method, blood clots are formed after coagulation and mixed with calculus, which cann...
