An endoscope working sheath for urological surgery

Abstract

The invention discloses an endoscopic working sheath for urological surgery, which comprises a working sheath, a telescoping mechanism is arranged inside the working sheath, an elastic buckle is fixed at the inner end of the telescoping mechanism, and the working sheath The end is fixed with a connecting frame, and the end of the connecting frame is connected with a stretching mechanism. A control switch is installed on the side of the end of the working sheath. The endoscopic working sheath used in urological surgery is pushed to slide by holding the rubber handle. Rail, so that the slide rail slides in the chute, and the end of the slide rail drives the endoscope and the water injection tube through the air bag to enter the surgical site. The operation is simple, fast and convenient, which greatly improves the efficiency of the operation. The position is controlled by the control switch to control the operation of the air pump. The air pump is inflated to expand the surgical site. On the one hand, it is convenient for the endoscope to perform inspection work. went well.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an endoscope working sheath for urological surgery. Background technique [0002] In the prior art: the patent application publication number CN 107320140 A discloses a kind of endoscope working sheath for urological surgery, which includes a working sheath that can be arranged in the working sheath of the endoscope and slides axially relative to the working sheath of the endoscope. There are guide wire channels, water injection channels and image channels extending from the back end of the mandrel to the front end of the mandrel, and the handle of the endoscope is provided with guide wire, water and endoscope respectively into the guide wire channel. 1. The guidewire joints, water injection joints and endoscope joints of the water injection channel and the image channel are cumbersome to operate, time-consuming and labor-intensive, do not have the function of opening...
