Abstract

The invention relates to the technical field of hepatobiliary surgery, and discloses a hepatobiliary surgery gall-stone extraction device which comprises an outer cylinder, a partition plate is fixedly mounted in the middle of the inner wall of the outer cylinder, a lead screw is rotatably arranged on the right side of the partition plate, a nut is in threaded connection with the outer wall of the lead screw, and a push block is fixedly mounted on the outer wall of the nut. A push rod is fixedly installed on the side, facing the partition plate, of the push block, and the left end of the push rod penetrates through the partition plate and is fixedly connected with a right side plate. During use, the end, provided with the collecting barrel, of the outer barrel extends into the body of a patient through a minimally invasive wound, then the rotary knob is screwed to enable the lead screw to rotate, the lead screw rotates to drive the nut in threaded connection with the outer wall of the lead screw to move left and right, and the nut moves left and right to drive the push rod to move left and right through the push block; and the right side plate, the collecting barrel and the left side plate can be pushed out of the outer barrel, so that calculi are conveniently collected and are collected into the collecting barrel, and the use is very convenient.

Description

technical field [0001] The invention relates to the technical field of hepatobiliary surgery, in particular to a device for removing gallstones for hepatobiliary surgery. Background technique [0002] Gallstones are mainly seen in adults, and their formation is related to a variety of factors. Any factor that affects the ratio of cholesterol to bile acid phospholipids and causes bile stasis may lead to the formation of gallstones; in recent years, due to improvements in living conditions and changes in eating habits, The incidence of gallstones is also increasing; [0003] The clinical treatment of cholelithiasis is mainly surgical treatment. During the operation, the stones in the biliary tract are taken out through the abdominal cavity incision or the abdominal cavity poke puncture device. For example, the authorized patent of China Patent Bulletin No. A novel clinical lithotripsy device for hepatobiliary surgery, comprising a first cylinder, one end of the first cylinder...
