The valve stem 303 is fixedly installed on the upper surface of the piston 302, and the top of the valve stem 303 extends to the outside of the valve tube 304, and the air supply pipe 307 is a hose. The inflation device 3 realizes the extraction and delivery of gas through the reciprocating motion of the piston 302 and the opening and closing of the valve plate 305. After being filtered, the gas enters the interior of the stripper through the air supply pipe 307 and is finally discharged from the air outlet 104, which helps to clear obstacles in the surgical field of view and make the surgical field of view clearer.

[0036] Specifically, the driving structure 401 includes a driving motor 4011, a rotating shaft 4012, and a gear set 4013 installed between the driving motor 4011 and the rotating shaft 4012. One end of the rotating shaft 4012 is fixed to the rotating disk 402, and the rotating shaft 4012 is connected to the inside of the mounting frame 2 through a bearing.

The adjusting seat comprises a shell with a concave shape, an adjusting screw rotatably installed inside the shell, and an adjusting block slidably arranged inside the shell and threadedly connected with the adjusting screw. A limiting rod for limiting the adjusting block is installed inside the shell.

[0037] The adjustment seat 404 is fixedly mounted on the front of the rotating disk 402, and the top end of the connecting rod 403 is hinged to the adjustment seat 404. A mounting slot is provided inside the mounting frame 2, and a buffer structure 405 connected to the valve stem 303 is provided in the mounting slot. The buffer structure 405 is composed of a buffer spring, a guide rod and a sliding block. The sliding block is slidably arranged in the mounting slot, and one side of the sliding block is fixed to the valve stem 303.

[0038] The working principle of the above embodiment is:

[0039] When the present invention is used, the slider 1051 is first connected to the slide groove 1025. At this time, the connecting end 105 is abutted against the outer surface of the abutting ring 1024. Then the connecting end 105 is pushed. After the slider 1051 is displaced to the top side of the slide groove 1025, the connecting end 105 is rotated. The elastic force of the elastic structure 1022 is used to fix the connecting end 105, so that the stripping device 103 can be disassembled and assembled. When in use, the piston 302 is reciprocated by the driving device 4. The chamber pressure is continuously changed during the reciprocating motion of the piston 302, and the opening and closing of the two valve plates 305 are cooperated to realize the air extraction and gas supply work. At this time, the gas enters the docking tube 1026 along the gas supply pipe 307 and is transported to the inside of the stripping device 103 through the docking tube 1026, and is finally discharged from the air outlet 104, so that the stripping device 103 has a gas processing function, which can make the surgical field of view clearer, and the force exerted on the mucosa during stripping is more uniform, and it is not easy to be cracked.

[0040] The installation method, connection method or setting method disclosed in this embodiment are all common mechanical connection methods, and they can be implemented as long as they can achieve their beneficial effects. In addition, the electrical components appearing in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Technicians in this field can control the electrical components through simple programming, and the existing disclosed power connection technology is also common knowledge in this field, so the specific structural composition and working principle will not be described in detail in this embodiment.
