一种盖体结构、鞘管及内窥镜系统
By designing a sliding tube and a flexible ring, the contradiction between the negative pressure suction seal and the smoothness of the insertion part in the endoscope sheath is resolved, realizing flexible adjustment of negative pressure suction and convenient operation of the insertion part, thus improving the ease of use of the sheath and the comfort of the endoscope system.

AI Technical Summary
Existing endoscopic sheaths cannot simultaneously achieve both a tight seal during negative pressure aspiration and smooth insertion, leading to complex procedures and increased surgical time when blockage occurs.
A cover structure was designed, which uses a sliding tube to drive a flexible ring to slide along the mating channel axially to achieve sealing of the insertion part and negative pressure adjustment. Through the insertion and mating, the sliding technique, the design of the sliding tube, the design of the sliding technique, the setting of the flexible ring, the sliding technique, the negative pressure adjustment, the setting of the flexible ring, the negative pressure suction sealing and the convenience of the insertion part are achieved.
It improves the efficiency of blockage removal, simplifies the sheath structure, increases ease of use, and enhances the comfort of using the endoscope system.
