Abstract

The utility model relates to a contraceptive ring placer, which comprises a rod body (1) and a clamping mouth (2). The clamping mouth (2) is arranged at the top end of the rod body (1) and consists of slightly inwards-concave finger-type bulges which face to each other. The rod body (1) is hollow. A push-and-pull rod (3) is arranged in the rod body (1). The top end of the push-and-pull rod (3) and the top end of the rod body (1) are arranged on the same level. A groove (4) is arranged at the bottom of the rod body (1). A bulge (5) which corresponds to the groove (4) is arranged on the push-and-pull rod (3). The length of the groove is equal to the height of the clamping mouth (2). The front ends of the two bulges of the clamping mouth (2) which face to each other are respectively and correspondingly bent inwards. The contraceptive ring placer has the advantages that the situation that a contraceptive ring is brought out when the placer is pulled out can be avoided, the contraceptive ring is not apt to fall off from the clamping mouth and is not apt to scratch the inner membrane of an uterus neck when the contraceptive ring passes through the uterus neck, bleeding during operation can be reduced and the occurrence of uterus perforation complications can be avoided.

Description

Ring introducer

Technical field

The instrument that uses when the utility model relates to a kind of placement of intrauterine devices, concrete is a kind of ring introducer.

Background technology

Intrauterine device claims birth control apparatus again, is that China uses maximum, most popular a kind of lady's contraceptive device.Intrauterine device generally is to send into cavity of uterus by ring introducer, but currently used ring introducer generally comprises the body of rod and clamp port, and clamp port is a fork-shaped.During use intrauterine device hung tag on the clamp port, intrauterine device is sent into the palace at the bottom of, placement device is extracted out got final product again.But this placement device has very big drawback in use, because clamp port is a fork-shaped, opening is big, and intrauterine device built on the sand, drops on clamp port easily, and in when operation during through cervix uteri, the front end of clamp port tends to endocervix is scratched, and causes hemorrhage; And after sending at the bottom of the palace, owing to firmly advance when entering cervical canal, intrauterine device is stuck in the clamp port easily, sometimes can take intrauterine device simultaneously out of when extracting placement device out, and is very inconvenient during use.

Summary of the invention

Goal of the invention of the present utility model is to provide a kind of ring introducer at the problems referred to above, can tightly clamp intrauterine device, prevents to drop, and can make again and not take intrauterine device when extracting placement device out out of.

This utility model is achieved through the following technical solutions: ring introducer, comprise the body of rod and clamp port, and body of rod top is a clamp port, clamp port is that the finger tabs by two relative summary indents constitutes; The described body of rod is a hollow, and there is push-pull bar inside, and push-pull bar its top in the body of rod flushes with the top of the body of rod; Body of rod bottom is fluted, has on the push-pull bar and the corresponding projection of groove, and the length of described groove and the height of clamp port equate; Two inwardly corresponding respectively bendings of front end of projection relatively of clamp port.

Adopt the good effect of technique scheme: this utility model is designed to hollow with the body of rod, inside is provided with the push-pull bar that can move forward and backward, in the time of at the bottom of intrauterine device enters the palace, promote push-pull bar, the body of rod moves backward simultaneously, intrauterine device can be released from clamp port, be prevented to take out of when placement device from extracting out intrauterine device; Body of rod bottom is provided with the groove that equates with the clamp port height, and, have on the push-pull bar and the corresponding projection of groove, projection can move forward and backward in groove, when promoting push-pull bar forward, because the height of the length of groove and clamp port is equal, therefore, the distance that push-pull bar moves is just in time released intrauterine device from clamp port, be placed into suitable position; Clamp port has changed habitual fork configuration, and two protruding relatively front ends of clamp port are inwardly corresponding respectively crooked, make that intrauterine device is not easy to drop on clamp port, when the process cervical canal, are difficult for endocervix is scratched, and are hemorrhage when reducing operation; And, under the thrust of push-pull bar appropriateness, intrauterine device can also be released from clamp port; Body of rod outer wall indicates scale, is convenient to grasp at any time placement device and enters the intrauterine degree of depth, and handled easily prevents the generation of perforation of uterus complication.

Four, description of drawings

Fig. 1 is a structural representation of the present utility model.

Among the figure: 1 body of rod, 2 clamp ports, 3 push-pull bars, 4 grooves, 5 projectioies.

Five, the specific embodiment: the utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is a structural representation of the present utility model, and as shown in the figure, ring introducer comprises the body of rod 1 and clamp port 2, and the body of rod 1 top is a clamp port 2, and clamp port 2 is that the finger tabs by two relative summary indents constitutes, and clamp port 2 is used for clamping intrauterine device.The body of rod 1 is a hollow, and there is push-pull bar 3 inside, and the top of push-pull bar 3 flushes with the top of the body of rod 1.The body of rod 1 bottom is fluted 4, has with groove 4 corresponding protrudingly 5 on the push-pull bar 3, and the height of the length of groove 4 and clamp port 2 equates.When promoting push-pull bar 3 forward, projection 5 can move forward along groove 4, because the height of the length of groove 4 and clamp port 2 equates that therefore, the distance that push-pull bar 3 moves forward equals the height of clamp port 2, just in time the intrauterine device in the clamp port 2 can be released.Two inwardly corresponding respectively bendings of front end of projection relatively of clamp port 2, the shape of formation just in time can be clamped intrauterine device, prevents to drop, and, when being subjected to the thrust of push-pull bar 3, intrauterine device can also be released.

Because the human body uterus is most for leaning forward or hypsokinesis, in order to make this utility model meet the shape of human body cavity of uterus in use more, make ring introducer convenient when the turnover uterus, arc-shaped bend with 5～10 ° of the body of rod 1 Front-end Design, the concavo-convex two sides of arc-shaped bend is two finger tabs of corresponding clamp port 2 respectively, are convenient to medical care precess.Simultaneously,, grasp the degree of depth that ring introducer enters the uterus at any time, be marked with scale, be convenient to operation, prevent the perforation of uterus at the body of rod 1 outer wall in order intrauterine device to be placed into suitable position.

During use, at first the intrauterine device that will sterilize with the clamp port 2 of ring introducer is clamped, and under the normal condition, the top of the top of push-pull bar 3 and the body of rod 1 flushes, and the projection 5 on the push-pull bar 3 is outside groove 4.Then, hand-held ring introducer is through vagina, cervix uteri, enter cavity of uterus, observe the scale on the body of rod 1 at any time, suitable when putting ring position when entering into, rotation push-pull bar 3 makes projection 5 on the push-pull bar 3 enter groove 4 on the body of rod 1, and projection 5 can move ahead along groove 4, because the length of groove 4 and the height of clamp port 2 equate, therefore, push-pull bar 3 moves forward, and simultaneously the body of rod 1 moves after gently, the intrauterine device that is clipped in clamp port 2 places is released, put into cavity of uterus.After placement finishes, ring introducer extracted out in the uterine cavity get final product.
