Description

A device for placing a cervical support

technical field

The utility model relates to the technical field of medical instruments, in particular to a device for placing a cervical support.

Background technique

The cervical pessary is a bowl-shaped device made of silicone, with a through hole at the bottom, and different types of cervical pessary can be selected according to the condition of the user's cervix. The invention of the cervical support originated from the treatment of gynecological pelvic floor organ prolapse. Sexual infections have to happen. In recent years, studies have found that placing a cervical pessary in the second trimester can reduce the risk of preterm birth in singleton women with suspected cervical insufficiency and improve neonatal prognosis. It is considered to be an effective treatment for prolonging gestational weeks in patients with twin pregnancy. The cervical pessary has the characteristics of non-invasive, safe, and less pain for patients, and has become a new method of preventing premature birth. Cervical pessary placement method: Pregnant women take the bladder lithotomy position, routinely disinfect the towel, and the surgeon uses a sterile speculum to check the cervix and select the appropriate model. During the operation, gently place the cervical pessary in the vagina, and fix it as high and tight as possible around the cervix. After the operation, check again with the speculum to confirm that the cervical pessary is placed on the cervix to ensure that the small inner diameter surrounds the cervix. around. A short period of postoperative observation should be performed to ensure that the patient has no complaints of discomfort, vaginal bleeding, or contractions. After the cervical pessary is inserted, the patient should avoid sexual life and continue to have regular check-ups. When the patient complains of discomfort or considers the displacement of the cervical pessary, the position of the cervical pessary can be readjusted. If there are no complaints or symptoms, the cervical pessary is removed around 37 weeks of pregnancy.

At present, cervical pessary placement is performed by obstetricians and gynecologists. It is necessary to hold the cervical pessary and insert it into the vagina. Pregnant women are prone to discomfort and lead to misplacement. During the operation, a vaginal speculum must be inserted at least twice. The vaginal mucosa is hyperemic during pregnancy. Obviously, most patients are psychologically afraid of repeatedly inserting the vaginal speculum. If the cooperation is not good, repeated operations may easily cause vaginal wall damage and induce uterine contractions. If the cervical columnar epithelium is significantly everted during pregnancy, there may be contact bleeding. And when the vaginal speculum is inserted for the second time, due to the relative relaxation of the vaginal wall during pregnancy and the blocking of the cervical pessary, it is difficult to expose the cervix, which is not conducive to observing the situation of the cervix, and also increases the discomfort of the pregnant woman.

Utility model content

The utility model aims at the above-mentioned shortcomings, and provides a cervical support placement device that is easy to use, reduces the frequency of use of the speculum, and reduces the discomfort of pregnant women.

In order to achieve the above object, the technical scheme of the utility model is as follows:

A device for placing a cervical pessary, comprising a sleeve, a push rod and grasping forceps; the sleeve is provided with a sliding cavity running through the upper and lower ends; the push rod is placed in the sliding cavity, and can be placed in the sliding cavity The cavity slides relative to the sleeve; the length of the push rod is longer than the sleeve, and the tail end passes through the bottom of the sleeve and is provided with a limit block; the grasper is hinged to the top of the push rod;

The upper end surface of the push rod is provided with an endoscope lens and a lamp cap; the grasper is hinged around the upper end surface of the push rod; the endoscope lens is connected to the external endoscope display device through a wire; the The inside of the push rod is provided with a battery, and the battery supplies power to the lamp head through a wire; the tail of the push rod is also provided with a switch key, which is connected to the battery through a wire; the wires are all installed inside the push rod.

As a further technical improvement, the surface of the above-mentioned push rod is provided with scale marks along the axial direction. After the cervical pessary is placed in the body, read directly on the push rod to know the depth of the cervical opening, which is convenient for recording and choosing a suitable cervical pessary model.

As a further technical improvement, the above-mentioned pliers include an arc-shaped piece; the arc-shaped piece is an elastic sheet arched outward; the arc-shaped piece is hinged at the top of the push rod. The curved pieces are made of silicone material. When the push rod slides axially upwards in the casing, the arc-shaped part after the top of the push rod extends out of the casing can gradually open to appear as a "claw" shape; when the push rod slides axially downward in the casing, the top of the push rod After being inserted into the casing, the arc-shaped part can be gradually shrunk and closed.

As a further technical improvement, there are at least three arc-shaped pieces as described above. It can hold the cervical pessary stably.

Working principle of the utility model:

When the push rod slides axially upwards or downwards in the casing, the grippers are driven to extend out of the casing and open, or the grippers are closed and shrunk into the casing. Under the action of the endoscopic lens and the lamp head, the device has a visualization function, and can observe the cervix after the device enters the body, find the cervix faster and more accurately, and facilitate the placement of the cervical pessary; It is convenient to check whether the placement position is appropriate, reduce the frequency of use of the speculum, avoid damage to the vaginal wall and reduce the discomfort of pregnant women.

When placing the cervical pessary, in vitro, the bottom of the push rod is the control end, push the push rod to slide upwards along the sliding cavity until the grasping forceps protrude from the sleeve and fully open, place the cervical pessary on the center of the grasping forceps, and then Pull the push rod down until the forceps are partially retracted into the cannula, so that the forceps close to hold the cervical pessary stably and extend into the body through the vagina; after reaching the uterus, push the push rod upwards, the forceps unfold, and the cervical pessary is placed to the cervix; after the placement is completed, continue to push the push rod upwards, not only to make the cervical support close to the cervix, but also to fully expand the grasping forceps, gradually withdraw from the sleeve and push rod, so that the grasping forceps are completely separated from the cervical ring, and finally Then pull the push rod downward, after the grasping forceps shrink into the cannula, the whole device is withdrawn from the body, and the cervical ring placement operation is completed.

The beneficial effects of the utility model:

1. The device of the present invention replaces the doctor to place the cervical support by hand, which is more convenient to operate, reduces the discomfort of pregnant women, has a high success rate of placement, and reduces the frequency of use of the speculum; under the action of the endoscopic lens and the lamp head of the present invention, it makes The device has a visualization function, which can observe the condition of the cervix after the device enters the body, find the cervical opening faster and more accurately, and facilitate the placement of the cervical pessary; after the placement is completed, it is also convenient to check whether the placement position is appropriate during the withdrawal process, further reducing vaginal peeping The frequency of use of the device can avoid damage to the vaginal wall and reduce the discomfort of pregnant women.

2. The push rod of the utility model is marked with a scale, and the depth of the cervix can be known by reading directly on the push rod, which is convenient for recording and avoiding damage to the cervix, and is reliable in use.
