[0053] Specifically, the adjusting member 300 is connected to the in-vivo fixator 400, and the adjusting member 300 can slide along the vertical rod 200 to adjust the height position of the in-vivo fixator 400 connected to the adjusting member 300, and the adjusting member 300 can rotate to adjust the insertion angle of the in-vivo fixator 400. At the same time, the vertical rod 200 can move relative to the fixed body 100, drive the in-vivo fixator 400 to move on the horizontal plane, and adjust the horizontal position. When in use, the in-vivo fixator 400 is first fixed on the patient, and the in-vivo fixator 400 is connected to the adjusting member 300, and the in-vivo fixator 400 is adjusted to the optimal treatment position. The rotation angle of the adjusting member 300, the relative position of the adjusting member 300 and the vertical rod 200, and the relative position of the vertical rod 200 and the fixed body 100 at this position are recorded, so that the in-vivo fixator 400 can be quickly adjusted to the optimal treatment position during the next treatment.

[0054] The present embodiment provides a vaginal cervical fixation device for fixing an in-vivo fixator 400, comprising: a fixing body 100, a vertical rod 200 and an adjusting member 300; since the adjusting member 300 is slidably connected to the vertical rod 200, the adjusting member 300 moves along the vertical rod 200 to adjust the vertical position of the in-vivo fixator 400 connected to the adjusting member 300, and the adjusting member 300 can rotate relative to the vertical rod 200 to adjust the angle at which the in-vivo fixator 400 is inserted into the human vagina and cervix, and the vertical rod 200 can slide along the surface of the fixing body 100 to adjust the horizontal position of the in-vivo fixator 400, thereby achieving a technical effect of accurately adjusting the position of the in-vivo fixator 400, and after the position adjustment is completed, all relative position data are recorded so that the in-vivo fixator 400 can be adjusted to the optimal position during subsequent treatment, thereby alleviating the technical problem in the prior art that the traditional vaginal fixator cannot accurately adjust the position of the vagina, cannot ensure that the treatment position is the same during each treatment, and affects the treatment effect.

[0055] Based on the above embodiments, Figure 3 , Figure 4As shown, in an optional embodiment, the adjusting member 300 in the vaginal cervical fixation device provided in this embodiment includes a height control block 310 and a connecting rod 320; the height control block 310 is arranged on the vertical rod 200, and the height control block 310 can slide along the vertical rod 200; a fixing hole 311 is provided on the height control block 310, and the connecting rod 320 is connected to the height control block 310 through the fixing hole 311, and the end of the connecting rod 320 away from the fixing hole 311 is detachably connected to the in-vivo fixator 400.

[0056] Specifically, a height control block 310 is mounted on the vertical rod 200. The height control block 310 can move along the vertical rod 200 to adjust the height position. The connecting rod 320 is connected to the height control block 310. The height adjustment block can drive the connecting rod 320 to move. A plurality of fixing holes 311 are arranged on the height control block 310. The plurality of fixing holes 311 are arranged on the height control block 310 at intervals along the vertical direction. Screws are passed through the connecting rod 320 and extended into the fixing holes 311. The screws limit the movement of the connecting rod 320. By selecting the fixing holes 311 at different positions, the position of the connecting rod 320 is adjusted, thereby changing the position of the in-body fixer 400 connected to the connecting rod 320.
