[0019] like Figures 1 to 5 As shown, the hysterectomy positioning and lifting device comprises a positioning rod 1, a hinged rotating rod 4 is provided at the end of the positioning rod 1, a sleeve 2 is provided on the positioning rod 1, an arc-shaped support cup 3 is provided at one end of the sleeve 2, and hinged locking handles 7 are provided on both sides of the other end. According to this structure, the rotating rod 4 is hidden at the end of the positioning rod 1, and enters the uterus from the cervix. The rotating rod 4 is unfolded and abuts against the bottom of the uterus for positioning. The unfolded rotating rod 4 can increase the contact area, and the sleeve 2 slides so that the arc-shaped support cup 3 abuts against the cervical opening for fixing. The sleeve 2 can be fixed to the positioning rod 1 by driving the locking handle 7 to rotate.

[0020] Preferred as Figures 1 to 3As shown, a through slot 101 is provided at the end of the positioning rod 1, one end of the rotating rod 4 is rotated against the end of the positioning rod 1 through a pin shaft, a pull wire 5 is fixed at the middle of the other end of the rotating rod 4, the positioning rod 1 and the handle 8 are hollow inside, the pull wire 5 passes through the positioning rod 1 and the handle 8 in sequence, and a stop block 9 is fixed at the end of the pull wire 5, and the stop block 9 is located outside the handle 8. A rotation stop block is provided between the rotating rod 4 and the positioning rod 1, and the stop block is respectively arranged at the horizontal state and the vertical state of the rotating rod 4 and the positioning rod 1, so that the rotation range of the rotating rod 4 is within 0~90°; further preferably, a torsion spring is installed between the rotating rod 4 and the positioning rod 1, and the elastic force of the torsion spring can make the rotating rod 4 always perpendicular to the positioning rod 1; when inserted into the human body, the rotating rod 4 is retracted and hidden in the through slot 101 at the end of the positioning rod 1 by the pull wire 5, and the rotating rod 4 can be unfolded by the elastic force of the torsion spring after reaching the specified position by releasing the pull wire 5.

[0021] The sleeve 2 is slidably sleeved on the outside of the positioning rod 1, and hinged seats 6 are fixed on both sides of the end of the sleeve 2. A hinged locking handle 7 is provided in the hinged seat 6. The end of the locking handle 7 is a cam. The locking handle 7 can be rotated to make the cam abut against the positioning rod 1, so that the sleeve 2 and the positioning rod 1 can be fixed; an arc-shaped supporting cup 3 is fixed on the top of the sleeve 2, and the arc-shaped supporting cup 3 is a quarter spherical shape. An arc-shaped bend 301 is provided at the end of the arc-shaped supporting cup 3. The arc-shaped bend 301 is made of rubber plastic material to avoid damage to the human body.

[0022] Preferred as Figures 4 and 5 As shown, the rotating rod 4 is hidden and retracted in the through groove 101 at the end of the positioning rod 1 under the action of the pull wire 5, so that it can smoothly pass through the cervix and enter the uterus. The end of the positioning rod 1 is against the bottom of the uterus, and then the pull wire 5 is released, and the rotating rod 4 is unfolded and against the bottom of the uterus through the torsion spring, thereby increasing the contact area and avoiding damage. The sliding sleeve 2 makes the arc-shaped support cup 3 against the cervix, and the arc-shaped support cup 3 can lift and fix the cervical opening, thereby achieving positioning. The arc-shaped bend 301 at the end of the arc-shaped support cup 3 avoids damage when it contacts the cervix; after the sleeve 2 is slid and fixed in place, the locking handle 7 is driven to rotate so that the cam is against the positioning rod 1 for locking, so that the positioning rod 1 is connected and fixed to the sleeve 2.
