Abstract

The utility model discloses a piece of postpartum uterine neck haemostatic forceps, comprising forceps leaves (1), forceps necks (2) and forceps handles (5), wherein, the front ends of the forceps necks (2) are provided with the forceps leaves (1) and the rear ends of the forceps necks (2) are provided with the forceps handles (5); two forceps necks are integrated into a whole through a forceps shaft (3) on the central section; the forceps leaves are oblong and slightly cambered; the edges of the forceps leaves are smooth and have no teeth and the central sections of the forceps leaves are hollowed-out. The forceps necks have enough length, thereby the postpartum uterine neck forceps is convenient for operation in a vagina; the forceps necks have enough width, thereby the postpartum uterine neck forceps can effectively clamp opening blood sinusoids of descending branches of uterine artery and lower segments of partial uterus; and due to the design of the forceps leaves which are smooth and have no teeth, the tissue contusion caused by the clamp is avoided.

Description

Puerperal the cervix uteri mosquito forceps

Technical field

This utility model relates to medical instruments field, especially a kind ofly is used for carrying out puerperal cervix uteri hemostatic mosquito forceps.

Background technology

The treatment of uterine inertia postpartum hemorrhage comprises the massage uterus, uses the palace agent of contracting, the filling of uterine cavity sliver, uterine vascular seam are pricked, body of uterus suture and cervix uteri clamp.The cervix uteri clamp is to close descending of uterine artery and the open blood sinus of part lower uterine segment by folder, and stimulates uterine contraction by the clamp effect, reaches and reduces hemorrhage purpose.Cervical clamps binder tool at present commonly used is anodontia sponge holding forceps, but sponge holding forceps pincers leaf width is limited, and length is not enough, effective clamp cervical tissue or need manyly clamp, and this has not only increased operation easier, and the while has also increased the injured probability of cervix uteri.At this situation, the new invention that meets the mosquito forceps that cervix uteri is dissected in puerperal is very necessary, and we have designed cervix uteri mosquito forceps in puerperal according to cervix uteri dissection in puerperal.

Summary of the invention

The purpose of this utility model provides a kind of effectively clamp blood sinus and reaches the hemostatic mosquito forceps.

The technical solution of the utility model is: a kind of puerperal the cervix uteri mosquito forceps, comprise pincers leaf, pincers neck and pincers handle, two pincers necks are connected as a single entity by the pincers axle at the middle part, described pincers leaf is oblong and radian slightly, the edge is smooth anodontia, middle hollow out.

The total length of described mosquito forceps is 26cm, and the length of described pincers leaf is 6cm, and width is 2cm, and the length of described pincers stem is 16cm.

The length of the front end of the central shaft of described pincers stem is 6cm, and the length of the rear end of central shaft is 10cm.

Described pincers handle is for semicircle and have buckle teeth.

The beneficial effects of the utility model are, the pincers neck has enough length, is convenient in the intravaginal operation, and the pincers leaf has enough width, the effective open blood sinus of descending of clamp uterine artery and part lower uterine segment, the smooth anodontia design that clamps leaf have been avoided the tissue contusion that causes because of clamp.When the uterine inertia postpartum hemorrhage takes place, use cervix uteri mosquito forceps clamp cervix uteri in puerperal, the open blood sinus of descending of on the one hand effective clamp uterine arteries of both sides and part, the clamp effect stimulates the uterine smooth muscle reflexive to shrink in addition, reaches to close the hemorrhage purpose of blood sinus minimizing.Compare with sponge holding forceps, its pincers leaf has enough width and length more effectively to press from both sides to close descending of uterine artery and the open blood sinus of part, and the design of pincers leaf arc more meets cervix uteri dissects, and can not cause damage to cervix uteri, and operation is simple.

The specific embodiment

As shown in the figure, puerperal, the cervix uteri mosquito forceps comprised pincers leaf 1, pincers neck 2 and pincers handle 5, the front end of pincers neck 2 is pincers leaf 1, and the rear end of pincers neck 2 is connected as a single entity by pincers axle 3 at the middle part for 5, two pincers of pincers handle neck, pincers leaf 1 is oblong and radian slightly, and the edge is smooth anodontia, middle hollow out, the total length of this mosquito forceps is 26cm, the length of pincers leaf 1 is 6cm, and width is 2cm, and the length of pincers stem 2 is 16cm, pincers stem 2 is 6cm in the length of the front end of pincers axle 3, and the length in the rear end of clamping axle 3 is 10cm.Pincers handle 5 is for semicircle and have buckle teeth 4.

Operation principle of the present utility model is:

After fetal placenta is given birth to, because the weak property of uterine contraction postpartum hemorrhage uses cervix uteri mosquito forceps clamp cervix uteri:

1. folder closes descending of uterine artery.

2. folder closes the open blood sinus of lower uterine segment.

3. the mechanical stimulus reflexive of clamp causes uterine contraction, promotes Placenta Hominis attachment area blood sinus closure.

4. clamp makes the ischemia anoxia, promotes local prostaglandins inflammatory mediator release, promotes uterine contraction.

5. clamp has stimulated the parasympathetic nervous of domination cervix uteri, stimulates and imports big mesencephalic centre into by Sensory nerve fibre, reflexive uterine contraction that causes.

Occupation mode of the present utility model:

1. after the vaginal delivery Placenta Hominis is given birth to, uterine contraction is weak carries out the cervix uteri Clamping when causing postpartum hemorrhage.

2. behind the routine disinfection, put the cervix uteri mosquito forceps in intravaginal, close up before and after the cervix uteri behind the lip, two 3 and 9 of cervix uteri mosquito forceps clamp cervix uteri are located, and cervix uteri mosquito forceps clamp point is apart from cervix uteri edge 1cm, and the degree of depth reaches bladder opisthotonos 0.5cm place.

3. after observing 15-30min behind the clamp, take a turn for the better as uterine contraction, cervical clamps is taken out in no active hemorrhage.
