[0036] Working process:

[0037] In use, the cantilever fixator 2 and the bedside guide rail 3 are fixed. By adjusting the position of the outer column pipe 601 in the cantilever fixator 2, the installation height and installation direction of the outer column pipe 601 can be adjusted, so as to conveniently adjust the position of the operation. By adjusting the hand wheel 502, the height of the rack inner column 602 can be adjusted, and the lifting hook mechanism 7 on the cantilever cross column 604 is driven to rise, and then the abdomen is pulled to cause a gasless space.

[0038] When the cantilever fixator 2 is operated, the height and direction of the outer column pipe 601 are adjusted by locking and loosening of the handle locking screw 201. The pressing plate 205 arranged in the clamping groove plate 207 is driven by the guide rail locking screw 203, and then the bedside guide rail 3 is pressed and fixed. The movable handle 202 is connected with the guide rail locking screw 203 through a pin shaft, and can be rotated in a limited space for locking operation.

[0039] When the transmission gear box 5 is operated, the transmission screw rod 504 is connected with the toothed structure of the rack inner column 602, and the lower part of the transmission screw rod 504 is connected with the upper bevel gear 505, which is engaged with the lower bevel gear 506, and the lower bevel gear 506 is fixedly connected with the adjusting hand wheel 502, so that rotating the adjusting hand wheel 502 can make the rack inner column 602 move up and down, and finally the position of the rack inner column 602 is locked by the inner column locking screw 501.

[0040] It can be seen that the design of the stand outer tube 601 and the rack inner column 602, together with the adjusting hand wheel 502, makes the cantilever cross column 604 and the drag hook mechanism 7 move conveniently, and the overall adjustment is convenient, and the height adjustment has high precision, and the distance control of the abdomen lifting is more accurate.

[0041] When the cantilever cross column 604 is operated, the cantilever cross column 604 can be folded reversely by rotating the shaft 6031.

[0042] When the drag hook mechanism 7 is operated, the moving frame 702 can connect the rotating hanging ring 703 and the drag hook 704 to move and fix at any position of the cantilever cross column 604, and the fixing is realized by the knob locking screw 701. The rotating hanging ring 703 has a rotatable function, which can make the drag hook 704 adapt to the operation of different angles. The tail part of the cantilever cross column 604 is provided with a limiting column 6041, which can limit the moving frame 702; at the same time, after the limiting column 6041 is removed, the drag hook mechanism 7 can be disassembled and installed, which is convenient for the overall system to be transported and carried.

[0043] When the damping support mechanism 9 is operated, the endoscope system 8 can be suspended at any position by the characteristics of the damping flexible rod 901, and the chuck mechanism 902 can firmly fix the endoscope system 8. Therefore, during the operation, the number of surgical personnel can be reduced without the aid of personnel to support the mirror.
