Abstract

The invention discloses a clinical calculus removing device for hepatobiliary surgery. The device comprises a barrel; a moving rod is arranged in the barrel, one end of the moving rod penetrates through the barrel and is in sliding connection with the barrel, and one end of the moving rod is connected with a pressing block; racks are arranged on the peripheral sides of the other end of the movingrod, two gears are symmetrically arranged on the two sides of each rack, and the gears are in engaged connection with the racks; the outer side walls, away from the moving rod, of the two gears are connected with clamping rods, and the clamping rods extend to the outer side of the barrel and are rotationally connected with the barrel through a rotating shaft. The gear and the rotating shaft are rotationally connected with the barrel; a clamping plate is arranged at the other end of the clamping rod; a moving ring is arranged on the outer side of the barrel, and a plurality of stretching mechanisms are arranged on the moving ring; by arranging the stretching mechanism, calculus removal is simplified for operators, operation steps are simplified, use is convenient, calculus removing efficiency is improved, and stability is good.

Description

technical field [0001] The invention belongs to the field of hepatobiliary medical equipment, in particular to a clinical stone removal device for hepatobiliary surgery. Background technique [0002] Gallstones are stones composed of bile compounds in the gallbladder, and also refer to diseases caused by stones in the gallbladder. The components of gallstones are cholesterol or cholesterol-based mixed stones and pigment stones. According to the location of the disease, gallstones can be divided into gallbladder stones and bile duct stones; the surgical treatment of gallbladder stones has been dominated by cholecystectomy for more than 100 years. , to avoid recurrence caused by residual stones. Therefore, gallbladder-preserving stone removal can not only avoid the complications caused by cholecystectomy, but also meet the patients' requirements for gallbladder preservation. [0003] For the existing stone removal device, it generally requires the cooperation of multiple pe...
