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.
