The invention discloses a liver and gall surgery calculus removing operation auxiliary device which comprises: an outer rubber pipe, wherein a balloon is installed on the outer side of the outer rubber pipe, and the left end of the outer rubber pipe is connected with a push sleeve; the inner rubber pipe that is mounted in the outer rubber pipe; the calculus removing cover that is in threaded connection with the interior of the right end of the inner rubber pipe, wherein a calculus removing skirt belt is installed on the outer edge of the right side of the calculus removing cover, a hollowed-out fixing plate is fixed to the middle of the interior of the calculus removing cover, and a lock catch mechanism is installed on the right side of the hollowed-out fixing plate; and the filtering mechanism that is arranged on the left side of the hollowed-out fixing plate, wherein a sealing cover is installed on the left side of the filtering mechanism, a guide pipe is connected to the left end of the sealing cover, and an air extracting pump is installed at the left end of the guide pipe. The balloon can open the biliary tract during inflation and swelling, so that the biliary tract can be expanded conveniently, the problem that the biliary tract is narrow and inconvenient to pass through a pipeline is solved, and meanwhile, the air pump can enable the calculus removing cover to form a negative pressure state, so that the stability of calculus grabbing is improved.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to an auxiliary device for stone removal in hepatobiliary surgery. Background technique [0002] Biliary stones are a common disease in surgery. Stones in the common bile duct can cause biliary obstruction secondary to jaundice, cholangitis, and even pancreatitis, which is life-threatening. Surgery is the only way to treat the disease. Choledochoscopic stone removal is a method commonly used in surgery for the treatment of biliary calculi at present. During this process, a fiberoptic choledochoscope is usually placed along the incision of the biliary tract. After the stone is found, the stone is removed with a stone removal mesh. [0003] However, the current stone extraction devices on the market are not convenient to expand the patient's biliary tract during use, and the biliary tract is narrow, which may easily cause stones to fall off when grasping and withdrawing the d...
