Description

cervical retractor

technical field

The utility model relates to a cervical retractor.

Background technique

In clinical work, with the improvement of living conditions, people pay more and more attention to health issues. Many diseases can be detected early when they are developing. The occurrence and development of cervical cancer is a slow process. Most of them are related to human nipples. It is related to viral infection. With the popularization of cervical screening, many of them are found in the stage of precancerous lesions (cervical intraepithelial neoplasia). The main treatment for cervical high-grade intraepithelial lesions is cervical conization.

However, for postmenopausal women, due to cervical atrophy, the cervical forceps cannot be used to clamp the cervix well, and thus the surgical cause cannot be better exposed, which affects the operation, and may even cause damage to the tissues and organs in the front and rear of the cervix, which may cause bladder damage. Vaginal leakage or rectovaginal leakage brings severe physical pain to the patient and serious mental torture to the doctor. At the same time, due to the repeated clamping of the cervical forceps, it brings serious physical pain to the patient and serious mental torture to the doctor At the same time, due to the repeated clamping of the cervical forceps, the tissue cells on the surface of the cervix are destroyed, which seriously affects the results of the pathology report. The possibility of missed diagnosis and misdiagnosis cannot be ruled out. Due to the difficulty in exposing the surgical field of view, intraoperative bleeding cannot be stopped in a timely and effective manner, which increases the number of patients undergoing surgery. The amount of bleeding affects the postoperative recovery of patients.

The utility model patent of China Publication No. CN214857010U discloses a cervical drill that is professional and pulls the cervix. It includes a working end, an extension section and a handle. The extension section includes a first end and a second end. Connection, the handle is integrally connected with the second end, the working end of the utility model is in a spiral shape, and can be wedged into the cervical tissue at a certain depth after applying force on the cervical assembly, and the spiral is embedded in the cervical assembly to generate a large pulling force on the cervix. In this way, better traction can be achieved. The extension section is designed to be bent, so that the handle end avoids the side of the cervix, which is more convenient to expose the cervix and facilitate the operation. The cervical drill will still cause damage to the cervix.

Utility model content

What the utility model aims to solve is to avoid the damage caused by the pulling of the cervix. In view of the above technical problems, a cervical retractor is proposed, which is realized through the following technical solutions: a cervical retractor, including a handle, one end of the handle is connected with a pulling unit, and the other end of the handle is provided with an injection joint .

For the optimization of the technical solution of the utility model, the handle is a hollow tube with two ends open, one end of the handle communicates with the pulling unit, and the other end of the handle communicates with the injection joint.

For the optimization of the technical solution of the utility model, the pulling unit is a water bladder, and the opening end of the water bladder is connected with the handle.

For the optimization of the technical solution of the utility model, the shape of the water bladder is an inverted cone, and the outer circle of the water bladder is provided with a plurality of anti-slip strips.

For the optimization of the technical solution of the utility model, the pulling unit includes a pulling rod and a water bladder, the pulling rod is connected with the handle, the upper end of the pulling rod is provided with two arc pieces, and the opening end of the water bladder is connected to the pulling handle. The upper end of the rod is connected, the water bladder is connected with the arc piece, and the lower end of the pulling rod is connected with the injection joint.

Compared with the prior art, the utility model has the beneficial effects that:

The technical scheme of the utility model adopts the method of connecting the water capsule body at one end of the handle, injecting water into the water capsule body, and using the water capsule body to pull the cervix to expose the cervical opening, which is convenient for the operation and will not damage the Damage to the cervix.

The technical scheme of the utility model is simple, easy to operate and low in production cost.

Detailed ways

The technical solutions in the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings 1-3 in the embodiments of the present invention.

Example 1

As shown in Figure 1, a cervical retractor includes a handle 1, one end of the handle 1 is connected with a pulling unit, the handle 1 is made of medical hard plastic, and the handle 1 is a tube with openings at both ends.

One end of the handle 1 is fixedly connected with the pulling unit, and the pulling unit communicates with the handle 1 to form a closed accommodating chamber.

The other end of the handle 1 is integrally formed with the injection joint 3, and the injection joint 3 communicates with the handle 1 and the pulling unit. The injection joint 3 adopts a sealed water injection joint 3, which has the same structure as the water injection joint 3 on the catheter. This is a known technique in the art.

The diameter of the handle 1 is 6-9 millimeters, the diameter of the injection joint 3 is 10-13 millimeters, and the handle 1 is convenient for doctors and nurses to take.

As shown in Figure 2, the material of the water bladder 2 is made of latex material, and the shape of the water bladder 2 is an inverted cone. After the water bladder 2 is injected with liquid, the water bladder 2 is filled, and the conical surface of the water bladder 2 In contact with the cervix, the handle 1 is pulled to pull the cervix outward to expose the cervix for easy operation.

As shown in Figure 2, there are many anti-slip strips on the tapered surface of the water bladder body 2, and the anti-slip strips and the skin of the cervix increase friction. In this embodiment, three anti-slip strips are used, and the anti-slip strips and the water bladder body 2 are integrally formed .

After the cervical retractor is sterilized, it is packaged in an outer package and sealed.

The movement process of this embodiment: first extend the retractor into the cervix, and inject water from the injection joint 3 to fill the water bladder 2. During the operation, pull the retractor outward to expose the cervix, which is convenient for operation.
