Abstract

The invention relates to a uterine forceps, which comprises: a pliers handle, a rotating shaft, a pliers rod and a pliers head. The pliers handle, the pliers rod and the pliers head are integrally formed by casting, and the two pliers rods are twisted together through the rotating shaft. The forceps head is composed of three non-closed or non-closed hollow U-shaped jaws at 90 degrees to the forceps rod, which is convenient for clinicians to accurately clamp the corresponding blood vessels on the lower uterine segment during the operation, temporarily blocking the blood supply of the uterine artery, and at the same time It is convenient to lift the uterus, fully stop the bleeding and expose the surgical field at the same time, it is convenient to suture and stop bleeding during the operation, and finally achieve accurate, satisfactory and non-invasive lower uterine blood vessel occlusion and suture hemostasis effect.

Description

a uterine forceps

technical field

The invention relates to a uterine forceps for blocking blood supply in medical treatment, in particular to a lower uterine forceps, which are used for blocking the blood supply of the uterine arteries located in the lower uterine segment and supplying the whole uterus.

Background technique

At present, during the cesarean section of the lower uterine segment due to placenta accreta or placenta previa, because the placenta separation surface is located in the lower uterine segment and cervix, the local bleeding after placenta separation is extremely turbulent. The hospital uses traditional hemostatic latex tape to bind the lower uterine segment, which is equivalent to arterial location. When this function is applied, the disadvantages of the traditional hemostatic latex tape include: 1) The latex tape needs to bind the lower uterine segment directly to cover the lower uterine segment tissue that needs to be sutured. 2) The diameter of the latex tourniquet is about 0.3cm. After binding the lower uterine segment, it can only block the corresponding compressed blood vessels, and cannot take care of other ascending or descending branches. 3) The latex tourniquet has a certain degree of elasticity, so the degree of tightness during use will have an impact on the hemostatic effect, and it is difficult to tighten completely, which cannot achieve a satisfactory hemostatic effect.

Contents of the invention

The present invention mainly solves the above-mentioned problems, and provides a method that is convenient for doctors to use during surgery, helps temporarily and accurately block the blood supply of the uterine artery, pulls and exposes the lower uterine segment, facilitates suturing, improves the effect of hemostasis treatment, and reduces the cost of equipment. as follows:

A uterine forceps, comprising a forceps handle, a forceps rod, and a forceps head, characterized in that the forceps head includes more than two non-closed jaws.

Further, the jaws are hollow.

Further, the claws form an angle of 80-100 degrees with the pliers rod.

Further, the jaws are arranged in parallel.

Further, the periphery of the hollow structure is U-shaped, square or circular.

Further, the opening is located away from the pincer rod.

Further, the length of the opening is 0.5-0.7 cm.

Furthermore, the area of the jaws is 0.5-1.5 square centimeters.

Further, the outer surface of the opposite part of the pliers is smooth.

Further, the pliers claws form an angle of 90 degrees with the pliers rod.

The beneficial effects produced by the present invention are as follows: the design of the non-closed hollow jaws of the forceps head can satisfy the need for clinicians to accurately clamp the corresponding blood vessels on the lower uterine segment; the non-closed hollow forceps head can take out the forceps head even if misoperation occurs during suturing ;The inner side of the forceps head has no tooth pattern design to avoid the loss of tissue caused by long-term clamping; different specifications and lengths of the forceps rod make this forceps suitable for patients with various conditions, and finally achieve accurate, satisfactory and non-traumatic uterine artery occlusion in the lower uterine segment .

detailed description

Below in conjunction with accompanying drawing and example the present invention will be further described:

As shown in FIG. 1 , the cervical blood vessel blocking forceps includes: 1. a forceps handle, 2. a rotating shaft, 3. a forceps rod, 4. a forceps head, and 5. a locking structure. The pliers handle 1, pliers rod 3 and pliers head 4 are integrally formed by casting, and the instrument includes two pliers rods 3, which are hinged together by rotating the drawer 2, and the pliers rods 3 are relatively rotatable.

The angle between the pliers rod 3 and the pliers head 4 is 90 degrees.

The pliers head 4 is composed of three non-closed hollow U-shaped parallel arrangements, and the opening is set at the attachment end of the pliers head away from the pliers rod, and the length is about 0.5 cm to 0.7 cm. The area of the U-shaped structure of the forceps head is between 0.5-1.5 square centimeters, and the surface of the U-shaped structure in contact with the lower uterine segment is a smooth surface structure without tooth lines. The cross-sectional area of the U-shaped structure is between 0.5-1.5 square centimeters

The length of the pincer rod 4 is adjustable, suitable for operations of different depths, and can be a scalable stepless adjustment structure or a scalable step-by-step adjustment structure.

The locking structure adopts a multi-tooth meshing structure.

The present invention can facilitate clinicians to accurately clamp the corresponding blood vessel position on the lower uterine segment. Even if misoperation occurs, the forceps head can be taken out to avoid loss of tissue caused by long-term clamping, and finally achieve an accurate, satisfactory and non-traumatic lower uterine segment uterus. Arterial blocking effect.
