Embodiment 1

[0040] A special auxiliary device for cervical cerclage, comprising an operation tube 1, a liquid delivery tube 2 pierced in the operation tube, a water bag 3 connected to the front end of the liquid delivery tube, and at least three forceps arms 5 arranged in the operation tube and a control piece for controlling the gathering or unfolding of the pliers arms, the pliers arms protrude forward from the operation tube, and each of the pliers arms gradually deviates from the axis of the operation tube from back to front and outwards It is unfolded into an umbrella shape, and the front end of the pliers arm is provided with pliers teeth 6 facing the axial direction of the operation tube. After the water sac is placed in the operation tube, it can partially or completely protrude from the front end of the operation tube, so as to push the amniotic sac by the water filling at the back.

[0041]The setting of clamp arms can be three, or four clamping points can be set like the tradit...

Embodiment 2

[0043] The difference from the above-mentioned embodiment is that the control member includes a collar 41, and a joystick 42 connected to the collar for controlling the reciprocating movement of the collar along the length direction of the operating tube. The operating tube is the same as the collar. The shaft is arranged or the axis line is arranged in parallel. The collar is sleeved outside the pliers arm and when the collar moves forward under the push of the control lever, all the pliers arms can be gathered together, and the control lever moves forward. Then extend through the rear end of the operating tube, and the liquid delivery tube passes through the collar.

[0044] In the unclamped state, the forceps arms protrude upwards from the operating tube and bend outwards. The collar covers all the forceps arms. After the operation tube is inserted in place, the forceps arms are distributed around the cervix, and the water bag is sent to the cervix. First inject water into ...

Embodiment 3

[0046] The difference from the above embodiments is that the pliers arms are elastic pliers arms. The design of the elastic pliers arm is more convenient, and it is also convenient to save the space in the operation tube. The pliers arm always has a tension to expand outwards so that the control lever can control the opening and closing of the pliers arms.

Abstract

The invention belongs to the field of medical instruments, and particularly relates to a cervix uteri cerclage special auxiliary instrument which comprises an operation tube, a liquid feeding tube arranged in the operation tube in a penetrating mode, a water bag connected to the front end of the liquid feeding tube, at least three forceps arms arranged in the operation tube and a control piece used for controlling the forceps arms to be gathered or unfolded. The forceps arms extend out of the operation tube forwards, the forceps arms gradually deviate from the axis of the operation tube from back to front and are unfolded outwards to be in an umbrella rib shape, and clamp teeth are arranged at the front ends of the forceps arms in the axis direction of the operation tube. The design of the operation tube is adopted, and at least three forceps arms and the water bag are integrally designed in the operation tube, so that all functional components are integrated into a whole through ingenious design, the space is saved, meanwhile, the operation is more convenient, and the operation can be completed by only one or two medical staff instead of several persons originally; and the operation space is large, the visibility is good, the operation is convenient, errors are few, the operation difficulty is greatly reduced, and the operation success rate is high.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a special auxiliary device for cervical cerclage. Background technique [0002] For some women with cervical insufficiency, such as those whose internal os dilates into a funnel or U-shaped change, especially pregnant women whose amniotic sac protrudes from the cervix, cervical cerclage is required. The existing cervical cerclage is to use induced labor water The amniotic sac is pushed back by the sac, and the cervix is ​​exposed with forceps. The top water bladder is generally clamped on three or four points of the cervix with three or four cervical forceps. The forceps are gathered together to pull the cervix together, and then the needle holder is put in to suture the cervix. Because there are too many cervical forceps and additional needle holders, there are many instruments, limited space, and very few operating angles of view, resulting in inconvenient operation, long operat...
