Ultrathin flexible arthroscope channel

An ultra-thin flexible arthroscope channel is made of a cylindrical integrally-formed flexible material, the two ends of the ultra-thin flexible arthroscope channel are turned outwards to form an expanded trumpet-shaped hemming structure, the interior of the channel is smooth and free of a closed structure, and the channel is closed by means of pressure of soft tissue around a surgical approach so as to achieve the water stopping effect; a non-closed water stop structure is arranged in the channel, so that interference on manufacturing instruments or sutures is avoided; the curled edge can be manually turned over to shorten or prolong the length of the channel so as to adapt to human body soft tissues with different thicknesses, so that the operation requirements of different parts are met, the horn-shaped curled edge structure in the articular cavity is tightly attached to the inner wall of the articular cavity by means of intra-articular pressure, and tissue edema caused by exosmosis of liquid to surroundin
