Novel clinical calculus removing device for hepatobiliary surgery department

Abstract

The invention relates to the technical field of medical instruments, and discloses a novel clinical calculus removing device for a hepatobiliary surgery department. The device comprises a box body, side plates, a semicircular body, a calculus placement groove, a first channel, a first operating rod, a pressing handle, a second channel, a second operating rod, a handle, first arc-shaped grooves, second arc-shaped grooves, third arc-shaped grooves, fourth arc-shaped grooves, a first arc-shaped plate, first sliding blocks, a second arc-shaped plate, second sliding blocks, an upper grabbing piece, third sliding blocks, a lower grabbing piece, fourth sliding blocks, an upper extrusion plate, a first elastic hinge, a lower extrusion plate, a second elastic hinge, a first connecting rod, a second connecting rod, a third connecting rod and a fourth connecting rod. The device is easy to use and high in innovativeness, after the device is used for clamping stones in the body of a patient, the stones can be clamped next time without being taken out of the device, the stones are crushed through a stone crushing electrode, and a plurality of stones can be contained in a stone containing groove.

Description

technical field [0001] The invention relates to the technical field of medical devices, and more specifically, relates to a new type of clinical stone removal device for hepatobiliary surgery. Background technique [0002] Hepatolithiasis is a common and frequently-occurring disease, which refers to stones that occur in any part of the hepatic duct system. According to the chemical composition of the stones, hepatolithiasis can be divided into cholesterol stones, pigment stones and mixed stones.
