Calculus taking device for hepatological surgery department

Abstract

The invention discloses a calculus taking device for hepatological surgery department. The calculus taking device structurally comprises clamping heads, a clamping shaft, clamping handles, a single shaft and a movable fixing strip; the clamping heads are respectively arranged on the clamping handles; the single shaft is connected with a shaft of the movable fixing strip; each clamping head consists of a turning clamping shaft, double clamps and a side device; the turning clamping shaft is connected with a shaft of the double clamps; and each double clamp consists of a side clamping block, an upper clamping plate, a lower clamping plate, a triangle device, a plate cutting device and a clapper structure. According to the invention, the clamping heads are adjusted to form a proper opening, and crushed calculi are clamped and taken out. The upper clamping plate is an inclined structure, and the side device is a groove-shaped structure, so that edges of the crushed calculi are effectively fixed, and smaller crushed calculi during clamping are prevented from scattering. Edges of calculi are cut through the plate cutting device, the crushed calculi are thoroughly removed, and the calculiare taken out more thoroughly, so that increase of medical cost is avoided, and redundant medical risks do not need to be borne by patients.

Description

technical field [0001] The invention relates to the field of hepatobiliary surgery, in particular to a stone removal device for hepatobiliary surgery. Background technique [0002] The concentration of stone-forming substances in human urine increases or the solubility decreases, and it is easy to crystallize and grow in local parts of the body to form stones, causing unbearable pain to patients. Larger stones need to be cut by surgery. With the continuous update of medical technology, only A small incision is required to remove larger stones. [0003] In the prior art, it is necessary to crush stones first in the process of stone extraction, and then take out the stones one by one. During the clamping process, due to the different sizes of the crushed stones, smaller broken stones are prone to scatter during clamping, resulting in incomplete stone extraction. Adding medical items to further clean up the gravel is time-consuming and laborious, which not only increases medic...

AI Technical Summary

Problems solved by technology

[0004] The main purpose of the present invention is to overcome the deficiencies of the prior art, and provide a stone removal device for hepatobiliary surgery, to solve the problem that during the stone removal process, the stones need to be crushed first, and then the stones are taken out one by one. , smaller broken stones tend to scatter during clamping, resulting in incomplete removal of stones, and additional medical matters are required to further clean up the broken stones in the later stage, which is time-consuming and laborious, which not only increases medical costs, but also brings unnecessary medical risks to patients. question
