Abstract
A cervical cerclage device comprises a cylinder-shaped cerclage device body made of elastic material, wherein convex teeth are arranged on the inner wall of the cerclage device body; in order to prevent abortion and premature delivery, all that is needed is to shove off the cerclage device body through a tool and nest the cerclage device body on a uterine cervix, which replaces complex suture, and clinical operation is simple and convenient, so that pain of a patient is reduced, tissues are not easy to be infected due to damage, and the use is safe and reliable. When the cervical cerclage device needs to be removed, all that is needed is to shove off the cervical cerclage device through a machine and take down, and the use is convenient; and moreover, gaps among the convex teeth can ensure that blood is normally supplied to tissues, so that the tissues can not necrotize, and the use is safe and reliable.
Description
Technical field
This utility model relates to medical apparatus, is specifically related to the cervix uteri ring bundle device that gynecological uses.
Background technology
Gravidic LCU is more than 3 centimetres, and late trimester of pregnancy, along with Cervical maturation, cervix uteri can slowly shorten, expand, and last and uterus becomes one, and forms birth canal and is convenient to childbirth.But women's mid trimester of pregnancy may cause the too early too fast shortening of cervix uteri, expansion because of various reasons and cause miscarriage.
Clinically in order to prevent that miscarriage from need carry out the cervix uteri suture operation, promptly use needlework that the cervix uteri in uterus is sewed up at present,, waited until that expected date of confinement or expected date of confinement close on the suture of dismantling again as the prophylactic treatment of recurrent abortion and premature labor.
Though the cervix uteri suture operation can prevent and treat premature labor or miscarriage, and is convenient during the needlework sew application, and needs of patients anesthesia when sewing up, the patient suffering increased.Stitching is bigger to the wound of tissue, be prone to cause complication such as infections, rupture of membranes, and if at the seam art failure timely dermal sutures out when miscarriage or childbirth sign occurring of pricking the hand, can cause uterine rupture or laceration of cervix.
Summary of the invention
To the problems referred to above, it is a kind of easy to use that this utility model provides, and can alleviate the patient suffering, and safe and reliable cervix uteri ring is pricked device.
To achieve these goals, the technical scheme of this utility model employing is following:
A kind of cervix uteri ring is pricked device, it is characterized in that, comprises the ring bundle device body of being processed by elastomeric material, and it is cylindrical that this ring is pricked device body, and this ring is pricked device inner body wall and is provided with double wedge.
Said double wedge is arranged according to spiral type or is formed two along ring bundle device inner body wall and encloses ring gears.
Said double wedge is a pawl.
The good effect of this utility model:
The cervix uteri ring of this utility model is pricked device, and it is the rubber-like cylindrical shape that ring is pricked the device body, cylinder heights little (being about 3 centimetres), and ring is pricked the device inner body wall and is provided with double wedge.For prevention of miscarriage and premature labor, only need strut this ring and prick the device body with instrument, will encircle then bundle device body be enclosed within promptly accomplish on the cervix uteri affected; Replace complicated suture, clinical manipulation and easy, minimizing patient's misery; And survivable tissue and cause tissue infection, safe and reliable.When needs are removed the cervix uteri ring and are pricked device, only need strut to take off and get final product with apparatus, easy to use.All be gapped between double wedge, can guarantee to organize normal blood supply and can be downright bad, safe and reliable.
Double wedge is arranged according to spiral type on ring bundle device inner body wall or is formed two circle ring gears, and dead ring that can be good is pricked device body difficult drop-off.
In order further to optimize effect, double wedge is designed to pawl, can prevent to greatest extent that dead ring bundle device body from coming off.
Description of drawings
Fig. 1 is the structural representation of this utility model.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Below in conjunction with specific embodiment this utility model is done further explain.
As depicted in figs. 1 and 2, a kind of cervix uteri ring is pricked device, comprises the ring bundle device body of being processed by elastomeric material 1, and it is cylindrical that this ring is pricked device body 1, and this ring is pricked device body 1 inwall and is provided with double wedge.
The cervix uteri ring of this utility model is pricked device, and it is the rubber-like cylindrical shape that ring is pricked device body 1, and cylinder heights is little, and ring is pricked device body 1 inwall and is provided with double wedge 2.For prevention of miscarriage and premature labor, only need strut this ring and prick device body 1 with instrument, will encircle bundle device body 1 then and be enclosed within on the cervix uteri and get final product minimizing patient's misery.When fetus will be born, only need strut rubber-like cervix uteri ring and prick device and it is taken off and removes get final product with apparatus, easy to operate, thus replaced the suture of existing complicacy, can also alleviate patient's misery, safe and reliable.
2 of double wedges leave the gap, can guarantee to organize normal blood supply and can be downright bad, and are safe and reliable.
In order further to optimize effect, double wedge 2 is designed to pawl, can prevent to greatest extent that dead ring bundle device body from coming off.
The foregoing description of this utility model only is to give an example for what explanation this utility model was done, and is not to be the qualification to the embodiment of this utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation and changes.Here can't give exhaustive to all embodiments.Conspicuous variation that every technical scheme that belongs to this utility model is amplified out or change still are in the row of the protection domain of this utility model.
