Description

A remove and cut that is used for quick stitches removing of cervical cerclage line

Technical Field

The utility model relates to a medical appliance, in particular to a pair of scissors for rapidly removing a ligature of a cervical ring.

Background

When a puerpera has a premature birth symptom, a doctor ties the periphery of a cervical orifice of the puerpera into a circle by using an operation line, so as to reduce the cervical orifice, repair and establish normal cervical orifice shape and function, enable pregnancy to be maintained to the full term or enable a fetus to survive and prevent premature birth of the infant.

Removing the cervical ring ligature at 37-38 weeks of gestation or before delivery, and opening the vagina of the lying-in woman by using a vaginal dilator when removing the cervical ring ligature; then holding forceps or oval forceps (a kind of forceps) to clamp one end of the thread from the outer wall of the cervix, and then lifting upwards; finally, the thread is cut off by inserting scissors.

However, the existing stitch removing mode has the following defects:

1. the difficulty of finding and clamping the cervical ring ligature by using tweezers or oval forceps is high, and severe pain can be brought to the puerpera when the cervical ring ligature is clamped and lifted.

2. The position of the cervical orifice is deep, the scissors with sharp tips need to be extended into the vagina, the visual field inside the vagina is poor, and when the scissors are used, the sharp tips of the scissors easily prick the vaginal wall to hurt a lying-in woman.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a remove and cut for quick stitches removing of palace neck ring ligature, its longer body of cutting can conveniently stretch into the vagina and press close to the palace neck mouth, removes the hook portion that cuts the front end and can catch on palace neck ring ligature smoothly, cuts off palace neck ring ligature through the control blade, not through convenient and fast, is difficult for causing the injury to the lying-in woman moreover.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a remove and cut for quick stitches are torn open to cervical cerclage, includes the handle and can stretch into the body of cutting in the vagina, cut the body tip and be equipped with thread take-off mechanism, thread take-off mechanism includes barb portion and blade, barb portion and cut and form the trimming cavity between the body, the tip of barb portion and cut leave the breach that is used for cervical ring ligature to get into between the body, the cutting edge of blade is towards the trimming cavity, blade and cut body swivelling joint, cut the inside control mechanism who is used for controlling the blade rotation that still is equipped with of body.

Preferably, the control mechanism comprises a handle and a transmission structure, the transmission structure is connected with the blade and the handle, and the handle controls the movement of the blade through the transmission structure.

Preferably, the transmission structure comprises a first connecting rod and a second connecting rod, two ends of the first connecting rod are respectively and rotatably connected with the blade and the end of the second connecting rod, the rod body of the second connecting rod is rotatably connected with the scissors body, and the other end of the second connecting rod is fixedly connected with the handle.

Preferably, the control mechanism further comprises a return spring for returning the blade.

Preferably, one end of the scissor body close to the barb part protrudes outwards to form a boss, and the farthest end of the outward protrusion of the boss does not exceed the end part of the barb part.

Preferably, the barb is provided with a protective means for preventing scratching of the vaginal wall.

Preferably, the protection mechanism is a soft sleeve sleeved and fixed on the outer wall of the end part of the barb part.

Compared with the prior art, the dismantling scissors for quickly dismantling the cervical cerclage line by adopting the technical scheme have the following beneficial effects:

compared with the existing tweezers or oval forceps, the dismantling scissors are longer in body and can conveniently extend into the vagina to be close to the cervical orifice for carrying out thread cutting operation.

The barb parts at the ends of the scissors bodies can smoothly hook the cervical ring for tying under the conditions of poor visual field and small operation space, and forceps or oval forceps are not required to be used for clamping and picking, so that the suture removing operation time is favorably shortened, and the pain of a puerpera is favorably relieved.

When the barb part hooks the cervical ring to tie the thread, the blade can be directly operated to cut the thread without going deep into the scissors to cut the thread, so that the thread inserting step is simplified, and the problem that the scissors are easy to damage the vaginal wall is solved.

And fourthly, the lug boss at the front end of the scissors body enables the part (the gap between the end part of the barb part and the scissors body) for hooking the thread to protrude outwards for a certain distance, so that the probability that the barb part hooks the cervical loop ligature can be improved during thread hooking.

Fifthly, the soft sleeve at the end of the barb can prevent the vaginal wall from being scratched.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

The demolition scissors for rapidly unraveling the cervical loop ligature 7 as shown in fig. 1 and fig. 2 comprise a handle 1 and a scissors body 2 which can extend into the vagina, wherein the end part of the scissors body 2 is provided with a unraveling mechanism 3, the unraveling mechanism 3 comprises a barb part 30 and a blade 31, a ligature chamber 32 is formed between the barb part 30 and the scissors body 2, a notch 33 for the cervical loop ligature 7 to enter is reserved between the end part of the barb part 30 and the scissors body 2, and the blade edge of the blade 31 faces the ligature chamber 32.

One end of the scissor body 2 close to the barb part 30 protrudes outwards to form a boss 20, and the farthest end of the boss 20 protruding outwards does not exceed the end part of the barb part 30.

The barb part 30 is provided with a protection mechanism for preventing the vaginal wall from being scratched, and the protection mechanism is a soft sleeve 301 which is sleeved and fixed on the outer wall of the end part of the barb part 30.
