As shown in fig. 1 and 2, a vaginal speculum for cervical surgery comprises a vaginal speculum body 1, wherein the vaginal speculum body 1 comprises an upper dilating blade 11, a lower dilating blade 12, an adjusting handle 13 and a grab handle 14, the upper dilating blade 11 and the lower dilating blade 12 are in duckbill shapes, the rear ends of the upper expanding leaf 11 and the lower expanding leaf 12 are hinged with each other, one side of the hinged end of the upper expanding leaf 11 is integrally formed with the adjusting handle 13, the handle 14 is integrally formed at the hinged end of the lower expanding blade 12, the adjusting screw rod 3 is arranged on the lower expanding blade 12, one end of the adjusting screw rod 3 penetrates through the adjusting handle 13 and then is connected with the outer side of the rear end of the grab handle 14, adjusting nut 4 is screwed on adjusting screw 3 above adjusting handle 13, adjusting screw 3 keeps away from under and expands 12 one end and set firmly circular spacing end 6, prevents that adjusting nut 4 from the terminal of adjusting screw 3 dropping. Go up to expand leaf 11 and expand leaf 12 down and be close to the outside ring of front end and be equipped with flexible ring-opening 2 that props, flexible ring-opening 2 that props includes two corresponding arc rings 21, two the arc ring 21 is hollow structure, two the arc ring 21 respectively with go up expand leaf 11 expand leaf 12 fixed connection down, two the both ends of arc ring 21 are the activity respectively and have been cup jointed pars contractilis 22, pars contractilis 22 keeps away from the one end of arc ring 21 is articulated each other. The telescopic opening ring 2 can expand or contract along with the opening and closing of the upper expanding leaf 11 and the lower expanding leaf 12 so as to play a role in supporting the side parts of the upper expanding leaf 11 and the lower expanding leaf 12, ensure the full exposure of the cervical operation part and be suitable for patients with vaginal relaxation.

In order to improve the stability of the telescopic part 22 in the process of stretching and retracting, a sliding block 23 is fixedly arranged at one end, far away from the hinge joint, of the telescopic part 22, and a sliding groove 24 matched with the sliding block 23 for sliding is formed in the side wall of the arc-shaped ring body 21. When the upper expanding leaf 11 and the lower expanding leaf 12 are opened, the telescopic part 22 extends out of the arc ring body 21, and the slide block 23 moves outwards along the slide groove 24. In addition, the end of the arc-shaped ring body 21 is fixedly provided with a limiting part 25, and the limiting part 25 is improved to prevent the telescopic part 22 from sliding off from the end of the annular ring body 21 due to overlarge spreading in the using process.

The rear end of the upper expanding blade 11 is provided with a smoking rod 5 communicated with the inner cavity of the vaginal speculum body 1. The smoking rod 5 is used for absorbing and eliminating smoke generated in the vagina during operation so as to improve the operation visual field and facilitate the operation.

The vaginal speculum body 1 is made of stainless steel. Compare in the vaginal speculum body 1 of plastics material, the vaginal speculum of this material is difficult to warp, and life is high, and is long. Because the stainless steel vaginal speculum conducts electricity and can be electrified to a patient in the operation process, the surface of the vaginal speculum body 1 is coated with an insulating glue layer (not shown in the figure) to play an insulating and protecting role.

The utility model discloses a theory of operation does: an operation channel is arranged between the upper expanded leaf 11 and the lower expanded leaf 12, and the upper expanded leaf 11 and the lower expanded leaf 12 extend into the vagina of a patient during an operation. Pressing adjustment handle 13 downwards, going up and expanding leaf 11 and expanding leaf 12 down and rotating around the pin joint and open, flexible prop ring 2 this moment and receive the effect of strutting, drive pars contractilis 22 and outwards stretch out and rotate around the pin joint of pars contractilis 22, realize opening in step flexible prop ring 2, at this moment, twist adjusting nut 4 downwards, prevent to press adjustment handle 13 return, can will go up and expand leaf 11 and expand leaf 12 down and flexible prop ring 2 and open the angle fixed. The telescopic support ring 2 plays a role in supporting the side parts of the upper expansion blade 11 and the lower expansion blade 12, so that the situation that muscles in the vagina relax inwards from the side parts of the upper expansion blade 11 and the lower expansion blade 12 to cover an operation channel due to the fact that the vagina of a patient relaxes is avoided, the sufficient exposure of a cervical operation part is guaranteed, and the operation quality is improved. After the use, upwards twist and move adjusting nut, press adjustment handle 13 return, go up and expand leaf 11 and expand leaf 12 closure down and drive flexible stay ring 2 closure simultaneously, convenience simple to use.
