AI Technical Summary

Technical Problem

The cleaning function of existing arthroscopic equipment is not synchronized between scraping and flushing, resulting in stubborn contaminants remaining, prolonging surgery time and increasing the risk of infection. In addition, the lens and cleaning mechanism are not physically isolated, resulting in field of view jitter and frequent interruptions in operation, affecting surgical efficiency and accuracy.

Method used

A multi-angle operating sheath for arthroscopic surgery has been designed. The internal structures of the scraping and cleaning parts are driven by a motor to move, achieving precise coordination between the scraping action and the flushing fluid injection. The lens is physically isolated from the cleaning structure to ensure that the lens is not disturbed during adjustment.

Benefits of technology

It improves the cleaning efficiency, reduces the operation time and infection risk, and enhances the stability and accuracy of the operation.

Abstract

The invention relates to the technical field of endoscopes, in particular to a multi-angle operation sheathing canal for arthroscopic surgery, which comprises an insertion tube and an observation tube arranged in the insertion tube, the insertion tube comprises an outer tube body, a protective cover arranged at the end part of the outer tube body, and a shifting and scraping part, a driving part and a cleaning part which are arranged in the insertion tube from left to right, and a spherical glass cover is clamped at the end part of the outer pipe body. According to the multi-angle operation sheathing canal for the arthroscopic surgery, a motor drives a disc and a shifting rod and drives a square frame to horizontally reciprocate, a linkage connecting rope pulls a line wheel, a volute spiral spring is utilized, a hanging strip can continuously swing, a cleaning part is synchronously triggered, a piston plate is driven to pressurize a liquid storage barrel, normal saline is forced to be injected into a hanging strip liquid passing groove through a liquid pipe, and the normal saline is injected into the hanging strip liquid passing groove; the flushing fluid is directionally sprayed from the fluid outlet hole, accurate cooperation of scraping action and flushing fluid spraying is achieved, dirt is mechanically scraped by swinging of the hanging strip, meanwhile, the observation window is scoured by high-pressure normal saline, and the cleaning efficiency is improved.
