Furthermore, the two water injection ports are respectively arranged on two sides of the cushion block and are opposite to each other. The two water injection ports are oppositely arranged to play a role in balancing and increasing the water injection pressure during water injection.
Furthermore, a water nozzle joint is connected to the water injection port. Reach the effect of being convenient for connect water injection device.
Furthermore, the water injection port is positioned at the rear part of the cushion block, and the distance between the water injection port and the front end of the sleeve body is greater than the depth of the sleeve body entering a human body.
Furthermore, an observation window is arranged at the front end of the sleeve body, and a water outlet of the water injection channel is communicated with the observation window.
Furthermore, a main channel pipe orifice communicated with the main channel pipe and an auxiliary channel pipe orifice communicated with the auxiliary channel pipe are arranged on the handle.
According to the technical scheme, the invention has the following advantages:
realize reaching the washing that the inside water injection carries out endoscope department blood or other debris when the work sleeve pipe stretches into human work from the outside to the washing of inside water injection through setting up the water injection passageway in the sleeve pipe body, guarantee that the field of vision of endoscope is clear, reach better observation effect, simultaneously, also can realize inhibiting the purpose of the outflow of blood in the blood vessel because of the water pressure of delivery port. In addition, two opposite water injection ports are arranged on two sides of the cushion block, water is injected into two sides simultaneously during use, and the effect of balancing water pressure during water injection is achieved.
