The lifting and adjusting part 2 can be flipped, and the front and rear positions of the surgical forceps 7 can be adjusted by flipping, and the lifting and adjusting part 2 can move left and right to adjust the position of the surgical forceps 7 left and right, so that the uterus can be adjusted in multiple directions when suspended, so that the doctor can perform the operation more conveniently and avoid uterine prolapse, which affects the doctor's operation. The lifting and adjusting part 2 is provided with an adjusting part 4. When the lifting and adjusting part 2 is reversed, the surgical forceps 7 can be driven to rotate in the opposite direction, so that the surgical forceps 7 can maintain a perpendicular angle to the uterus. A rotating adjusting part 5 is provided between the two supporting frames 1 for installing and fixing the lifting and adjusting part 2, and the rotating adjusting part 5 can drive the lifting and adjusting part 2 to flip, thereby driving the uterus to swing back and forth.

[0024] like Figure 1-4As shown, the lifting and lowering adjustment part 2 includes a limit plate 21 arranged between the two support frames 1, a top plate 29 is arranged between the two support frames 1, and the limit plate 21 is fixedly installed on the top plate 29, the cross-sectional shape of the top plate 29 is non-circular, a gear 22 is arranged in the limit plate 21, and the gear 22 can be lifted and lowered along the height direction of the limit plate 21, two racks 23 are arranged in the limit plate 21, and the two racks 23 are respectively located on the left and right sides of the gear 22 and meshed with the gear 22, and the two racks 23 can be lifted and lowered along the height direction of the limit plate 21, and the side faces of the two racks 23 away from each other are fixedly connected with a connecting plate 25, and the ends of the two connecting plates 25 away from each other are fixedly connected with a mounting plate 26, and the bottom ends of the two mounting plates 26 away from each other are hinged with a fixing plate 27, and the surgical forceps 7 are installed at the bottom end of the fixing plate 27, and the two connecting plates 25 are rotatably connected with a connecting rod 24, and the top end of the connecting rod 24 extends to the top of the top plate 29, connecting The surface of the rod 24 is sleeved with an elastic reset member 28, and the two ends of the elastic reset member 28 are respectively fixedly connected to the side of the top plate 29 and the connecting plate 25 that are close to each other. The elastic reset member 28 is a tension spring, and a limiting portion 3 is arranged on the top plate 29. The limiting portion 3 can fix one of the connecting rods 24 alone, and can also fix the two connecting rods 24 at the same time. When one of the connecting rods 24 is fixed, the gear 22 is connected to the external driving source, so that the gear 22 is lifted and lowered along the height direction of the limiting plate 21. When the gear 22 is lifted and lowered, it can drive the other rack 23 on the side that is not fixed to be lifted and lowered. When the rack 23 is lifted and lowered, it can drive the surgical forceps 7 to be lifted and lowered through the connecting plate 25, the mounting plate 26 and the fixing plate 27, so that one side of the uterus is suspended, and vice versa, the uterus on the other side can be suspended. When the two connecting rods 24 are locked at the same time, the two racks 23 can be driven to be lifted and lowered at the same time, and both sides of the uterus are suspended at the same time.

[0029] Working principle: First, the uterus is clamped and fixed by the surgical forceps 7, and then, according to the surgical situation, the lifting and adjusting part 2 drives one of the surgical forceps 7 to be lifted or lowered, or drives both surgical forceps 7 to be lifted or lowered at the same time, thereby pulling the uterus upward for suspension, and then the rotating adjusting part 5 is driven to make the lifting and adjusting part 2 swing back and forth, and the position of the surgical forceps 7 can be adjusted back and forth by swinging, and then the driving adjusting part 4 is used to make the surgical forceps 7 and the uterus remain vertical, so that the front and back position of the uterus can be adjusted, and finally the translation driving part 6 is started to make the lifting and adjusting part 2 translate left and right, so that the left and right direction of the uterus can be adjusted. Through the coordinated use of the three, the uterus can be suspended in multiple directions and angles, so that medical staff can perform the operation more conveniently, improve the safety of the operation, and improve the efficiency of the operation.
