Gallbladder polypus cutter

Abstract

The invention discloses a gallbladder polypus cutter which is characterized by comprising a cylindrical outer sleeve pipe, an operating end, a limiting plate, a metal lead and a pair of V-shaped tongs; the operating end is installed on the limiting plate; the limiting plate is installed in a groove at the bottom end on the inner wall of the cylindrical outer sleeve pipe, and the limiting plate can move up and down or rotate in the groove; the metal lead is installed in the cylindrical outer sleeve pipe, one end is connected with the limiting plate, and the other end is connected with the pair of V-shaped tongs; the pair of V-shaped tongs is installed at the outer side of the cylindrical outer sleeve pipe, and the bottom of the pair of V-shaped tongs is connected with the metal lead; when the operating end is pulled, the limiting plate which is installed in the groove and connected with the operating end moves therewith, and the metal lead is driven to move; and while the metal lead moves, the pair of V-shaped tongs is driven to be retracted to the inside of the cylindrical outer sleeve pipe. Because the installation design of the limiting plate is adopted by the invention, the angles of the gallbladder polypus cutter can be freely adjusted for cutting the gallbladder polypus in an obstructed direction, and the gallbladder polypus cutter is convenient to clamp, thereby avoiding repeated adjustment.

Description

technical field [0001] The invention relates to a medical device, in particular to a device used in human gallbladder polypectomy or extirpation. Background technique [0002] Most gallbladder polyps are benign, and the proportion of adenomas in cholecystectomy specimens is only 1.1%, while the malignant transformation rate is 1.5%, which is considered to be a precancerous lesion of gallbladder cancer, so gallbladder polyps are rarely malignant. It is unscientific to perform cholecystectomy for benign lesions. For the consideration of protecting gallbladder function and avoiding long-term complications after cholecystectomy, cholecystectomy is not necessarily performed for the treatment of gallbladder polyps. The recurrence rate of "endoscopic minimally invasive gallbladder preservation and polyp extraction" method is only 1%. During the operation, the polyp is removed under the direct vision of the choledochoscope, and the polyps with objections are immediately sent for fr...
