The working principle of the invention is as follows: firstly, in the visual field of a laparoscope, an operator holds the anti-skid rubber sleeve 506 on the outer sleeve 501 with the left hand and slightly pushes the end cover 502 with the right hand, the supporting rod adjusting mechanism 1 at the front end of the outer sleeve component 5 is inserted into the uterine cavity of a patient through the vagina of the patient, the depth of the outer sleeve component 5 entering the body of the patient is controlled through the positioning sleeve 507, and the positioning collecting cup 3 is fixed after being positioned at the cervical position of the patient; then, the rotating nut 211 is twisted clockwise by the right hand, so that the externally threaded pull rod 209 rotates and moves forward, the externally threaded pull rod 209 pulls the first rotating arm 207 to rotate counterclockwise around the first rotating shaft 208, the first rotating arm 207 pulls the second pull rod 206 to move backward, and therefore the pull rod connecting sleeve 204 connected with the front end of the second pull rod 206 pulls the first supporting tube 202 to drive the supporting ball 201 to rotate to a proper angle (as shown in fig. 5), and a part of the uterus is jacked up through the supporting ball 201; meanwhile, the air supply device leads air into the fixed sealed cavity 101 from the air inlet 109 along the air hose 108, the pressure in the sealed cavity between the bottom of the fixed sealed cavity 101 and the piston push tube 102 increases, the piston push tube 102 is pushed to slide forwards against the spring force of the spring 110, the bottom ends of the first stay bar 103 and the second stay bar 104 hinged with the piston push tube 102 slide forwards along with the piston push tube 102, the top ends of the first stay bar 103 and the second stay bar 104 push up the transverse stay bar 105, because the first stay bar 103 and the second stay bar 104 are always parallel relatively, the transverse stay bar 105 is always kept parallel in the process of being pushed upwards, the third stay bar 106 hinged with the other end of the transverse stay bar 105 is pushed up along with the transverse stay bar 105, when the piston boss of the piston push tube 102 moves to the top of the fixed sealed cavity 101, the air supply is stopped, and at this time, the whole support bar adjusting mechanism 1 is completely pushed open, to achieve further support of the inner wall of the uterus (as shown in figure 6); during the operation, according to the requirement, the flushing fluid is input into the first supporting tube 202, the second supporting tube 203 and the supporting ball 201 from the flushing fluid connecting inlet 406 to enter the uterus of the patient to flush the inner wall of the uterus of the patient; the washing waste liquid and tissue fluid and blood generated in the operation process directly flow into the positioning collecting cup 3 and enter the liquid absorbing sponge 402 through the positioning collecting cup 3 and the porous fixed filter plate 401 behind the positioning collecting cup, when the liquid absorbing sponge 402 absorbs a certain amount of liquid, the push plate 405 is pushed to make the porous movable filter plate 403 move forwards to press the liquid absorbing sponge 402, so that the tissue fluid and the washing waste liquid in the liquid absorbing sponge 402 overflow and flow to the waste liquid discharge port 503 and are discharged to the medical waste liquid collecting box through the waste liquid discharge pipe 505 (as shown in fig. 7); after the operation is completed, the gas in the fixed sealed cavity 101 is exhausted from the gas inlet 109, the pressure in the sealed cavity between the bottom of the fixed sealed cavity 101 and the piston push tube 102 is reduced, the piston push tube 102 is pushed to slide backwards under the action of the elastic force of the spring 110, the bottom ends of the first support rod 103 and the second support rod 104 are pulled to slide backwards along with the piston push tube 102, the top ends of the first support rod 103 and the second support rod 104 horizontally fold the transverse support rod 105 downwards, and the third support rod 106 hinged with the other end of the transverse support rod 105 is folded downwards along with the transverse support rod 105 until the whole connecting rod mechanism is axially folded on the tube wall of the second support tube; turning the rotating nut 211 anticlockwise to enable the externally threaded pull rod 209 to rotate and move backwards, and the externally threaded pull rod 209 pulls the first rotating arm 207 to rotate clockwise around the first rotating shaft 208; the first rotating arm 207 pulls the second pull rod 206 to move forward, so that the pull rod connecting sleeve 204 connected with the front end of the second pull rod 206 pulls the first supporting tube 202 to drive the supporting ball 201 to rotate to the initial position; finally, the outer cannula 501 is pulled until the entire device is removed from the patient.
