An operating table 103 is fixedly connected to the inner wall of the frame 101. A vent 102 is provided at the top of the frame 101. A sterilization mechanism is provided inside the frame 101. An operator operates on the operating table 103, and the sterilization mechanism provides a sterile condition for the table top of the operating table 103.

[0022] In a preferred embodiment, the dust collecting mechanism is arranged inside the frame 101, and the dust collecting mechanism includes a connecting cover 201 movably arranged on the inner wall of the frame 101, the top of the connecting cover 201 is fixedly connected with a dust collecting cover 202, the top of the dust collecting cover 202 is fixedly connected with a bellows 203, the top of the bellows 203 is fixedly connected to the top of the inner wall of the frame 101, the interior of the bellows 203 is connected to the interior of the vent 102, the top of the frame 101 is provided with a dust extraction component, and a positioning mechanism is provided between the connecting cover 201 and the frame 101. Through the cooperation of the dust extraction mechanism, Negative pressure can be generated inside the connecting cover 201 and the dust collecting cover 202, so that the dust above the operating table 103 can be sucked out. Moreover, through the arrangement of the bellows 203, the connecting cover 201 and the dust collecting cover 202 can be lifted up and moved while ensuring that a stable negative pressure is generated inside the connecting cover 201 and the dust collecting cover 202. The positions of the connecting cover 201 and the dust collecting cover 202 can be adjusted according to the operating height on the operating table 103, so that a stable negative pressure can be generated on the surface of the operating table 103, thereby sucking out the dust on the surface of the operating table 103, thereby improving the dust collection efficiency.

[0023] Among them, the dust extraction component includes a dust extractor 301 installed on the top of the frame 101, and a connecting pipe 302 is provided at the input end of the dust extractor 301. One end of the connecting pipe 302 is fixedly connected to the top of the frame 101, and the inner wall of the connecting pipe 302 is connected to the inside of the vent 102. When the dust extractor 301 works, negative pressure can be generated inside the connecting pipe 302, and then through the connection of the vent 102, the negative pressure is transmitted to the inside of the bellows 203 until it reaches the inside of the dust collecting hood 202 and the connecting hood 201. The dust extractor 301 is electrically connected to the external power supply through an external switch, which is convenient for the operator to operate the dust extractor 301, thereby improving the safety and convenience of the operation of the dust extractor 301.

[0024] Among them, the positioning mechanism includes a fixed block 401 fixedly connected to the inner wall of the connecting cover 201, a movable hole 402 is opened on one side of the fixed block 401, the inner wall of the movable hole 402 is movably connected with a positioning rod 403, and the inner wall of the frame 101 is spaced apart with a plurality of positioning holes 404, the outer wall of the positioning rod 403 is movably connected with the inner wall of one of the positioning holes 404, a pulling mechanism is arranged at one end of the positioning rod 403, and an extrusion mechanism is arranged inside the fixed block 401. When the connecting cover 201 is moved to the desired position, the positioning rod 403 is moved out of the movable hole 402 and the positioning rod 403 is inserted into the corresponding positioning hole 404, so that the connecting cover 201 can be positioned, so that the dust collecting component can work stably.

[0025] Among them, the pulling mechanism includes a pull ring 501, and the end of the positioning rod 403 away from the positioning hole 404 passes through the inner wall of the movable hole 402 and is fixedly connected to the outer wall of the pull ring 501. Through the setting of the pull ring 501, the positioning rod 403 is convenient to move, thereby improving the convenience of operating the positioning mechanism.

A spring 603 is arranged on one side of the limiting ring 602. The spring 603 is sleeved on the outer wall of the positioning rod 403. Through the elastic action of the spring 603, the spring 603 always squeezes the limiting ring 602, so that the positioning rod 403 always has a tendency to move toward the positioning hole 404, so that the positioning rod 403 can be stably inserted in the positioning hole 404 when the positioning rod 403 is not subjected to a large pulling force, thereby improving the stability of the positioning mechanism.

[0027] Among them, the sterilization mechanism includes multiple sterilization lamps 701, which are installed at intervals on the back of the inner wall of the frame 101. The inside of the frame 101 is sterilized by the operation of the sterilization lamps 701. The multiple sterilization lamps 701 are electrically connected to the external power supply through external switches, which is convenient for operators to control the multiple sterilization lamps 701 separately, so that the multiple sterilization lamps 701 can work separately, thereby improving the safety and convenience of operating the sterilization lamps 701.
