The utility model realizes the clamping and expanding of the clamp through the expansion and contraction movement of the air bag ring sleeved on the clamp body, and realizes the inflation and deflation of the air bag ring outside the body through the slender hose, so that the utility model has simple integral structure and convenient use, and effectively avoids the pouring medicine in the uterine cavity from flowing out from the cervical orifice.

Description

Cervical orifice clamp

Technical Field

The utility model relates to the technical field of medical appliances, in particular to a cervical clamp.

Background

Under the prior art, in order to improve the success rate of test-tube infants, the operation of filling the uterine cavity into the mother body before embryo transplantation is usually carried out, namely, medicines are injected into the uterine cavity of the mother body for treatment, so that the endometrial environment is improved, the endometrial microcirculation is promoted, the endometrial receptivity is improved, and the embryo implantation effect is improved.

Clinically, the vaginal speculum is required to be used for vaginal dilation in the uterine cavity perfusion treatment, then a catheter is inserted into the uterine neck and extends into the uterine cavity, and the drug is injected into the uterine cavity, so that the cervical orifice is required to be clamped when the drug is injected, and the drug is prevented from flowing out from the cervical orifice; similarly, such operations are also required in performing artificial insemination; there is a need for a simple, easy to operate instrument that can clamp the cervical os.

Disclosure of Invention

The utility model aims to provide a cervical clamp for solving the problems in the background technology.

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

the cervical clamp comprises a clamp body, wherein the clamp comprises a first clamping plate and a second clamping plate which are in circular arc shape, the tail ends of the first clamping plate and the second clamping plate are rotationally connected, and tooth-shaped structures are arranged on the inner sides of the front ends of the first clamping plate and the second clamping plate; the outer surface of the clamp body is sleeved with an air bag ring, and the air bag ring is limited by a plurality of fixing rings arranged on the outer surfaces of the clamping plate I and the clamping plate II; the clamp body is clamped and opened through the expansion and contraction movement of the air bag ring.

Further, the air hole of the air bag ring is connected with an elongated hose, and the air in the air bag ring is inflated and discharged through the elongated hose.

Further, one axial end of the slender hose is communicated with the air hole of the air bag ring, the other axial end of the slender hose is connected with a first opening and a second opening, a three-way structure is formed, silica gel is filled in the first opening, and the second opening is provided with a switch structure.

Further, the clamp body is made of any one of medical natural rubber, silicon rubber and polyvinyl chloride.

The utility model realizes the clamping and expanding of the clamp through the expansion and contraction movement of the air bag ring sleeved on the clamp body, and realizes the inflation and deflation of the air bag ring outside the body through the slender hose, so that the utility model has simple integral structure and convenient use, and effectively avoids the pouring medicine in the uterine cavity from flowing out from the cervical orifice.

Drawings

FIG. 1 is a schematic diagram of the overall structure of the present utility model;

in the figure: 1. a clamping plate I; 2. a clamping plate II; 3. a tooth-shaped structure; 4. an air bag ring; 5. a fixing ring; 6. an elongated hose; 7. an opening I; 8. and an opening II.

Detailed Description

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model, a preferred embodiment of the utility model is described in detail below with reference to the accompanying drawings. The utility model may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit or scope of the utility model, which is therefore not limited to the specific embodiments disclosed below.

The cervical orifice clamp shown in fig. 1 comprises a clamp body, wherein the clamp body is made of polyvinyl chloride, the clamp comprises a circular arc-shaped clamping plate I1 and a circular arc-shaped clamping plate II 2, the tail ends of the circular arc-shaped clamping plate I and the circular arc-shaped clamping plate II are rotationally connected through a hinge, tooth-shaped structures 3 are arranged on the inner sides of the front ends of the clamping plate I and the clamping plate II, and the cross section of each tooth-shaped structure is triangular; the polyvinyl chloride material is softer, and the contact area during clamping is reduced through the tooth-shaped structure, so that the damage to the cervical orifice is avoided; and the cervical orifice is circular, so that the circular arc-shaped clamping plate can better wrap the cervical orifice and clamp the cervical orifice.

Further, an air bag ring 4 is sleeved on the outer surface of the clamp body, and the air bag ring is limited by a fixing ring 5 arranged on the outer surfaces of the clamping plate I and the clamping plate II; the clamp body is clamped and opened through the expansion and contraction movement of the air bag ring, and in particular use, in order to avoid abrasion of the air bag ring by the fixing ring, the inner diameter of the fixing ring is not smaller than the diameter of the largest cross section of the air bag ring after expansion.

In the preferred embodiment, the air hole of the air bag ring 4 is connected with an elongated hose 6, and the inflation and the deflation of the air bag ring are realized through the elongated hose, specifically, one axial end of the elongated hose is communicated with the air hole of the air bag ring, the other axial end of the elongated hose is connected with a first opening 7 and a second opening 8, a three-way structure is formed, the first opening is filled with silica gel, and the second opening is provided with a switch structure.

In specific use, the oval forceps are used for clamping the clamp of the device to be sent into vagina, and the oval forceps are placed at the cervical orifice, so that the upper edge and the lower edge of the cervical orifice are positioned between the clamping plate I1 and the clamping plate II 2; slowly injecting air into the silica gel in the first puncture opening of the syringe by using the syringe to expand the air bag ring, so as to squeeze the first clamping plate and the second clamping plate to close so as to clamp the cervical orifice; stay for a sufficient time according to the treatment requirements; after the treatment is finished, the cover of the opening II is opened, gas is discharged, the air bag ring is contracted and reset, the clamp is loosened and falls off, the hose is pulled to take out the whole, the whole operation is simple, and the patient can independently finish the treatment.

The above embodiments are merely illustrative of the preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model, and various modifications and improvements made by those skilled in the art to the technical solution of the present utility model should fall within the protection scope defined by the claims of the present utility model without departing from the design spirit of the present utility model.
