Description

Technical Field

[0001] The utility model relates to the technical field of medical treatment, in particular to a uterine cavity hemostatic forceps with a dilating function. Background Art

[0002] Hemostatic forceps are a medical device used clinically, often used to stop bleeding during surgery or rescue. Hemostatic forceps are an indispensable surgical instrument during gynecological and obstetric surgery. However, there is a common problem with current hemostatic forceps. They are unable to clamp the patient's affected area while expanding the patient's uterine cavity and stop bleeding, causing the inner wall of the patient's uterine cavity to adhere under the influence of blood.

[0003] The invention discloses an intrauterine hemostatic forceps for use in obstetrics at a window in the Chinese utility model patent application publication specification CN210843281U. The invention inserts the head end of a round tube into the patient's uterine cavity, rotates the threaded rotating tube along the threaded fixed tube, and moves the threaded rotating tube backward along the threaded fixed tube. Then, the rotating ring pulls two arc-shaped expansion blocks to open through two push rods, so that the arc-shaped expansion blocks support the inner wall of the patient's uterine cavity, which is convenient for subsequent operation of the hemostatic forceps. At the same time, it will not cause the inner wall of the uterine cavity to adhere under the influence of blood stains. The pulling ring is pulled through the connecting steel wire belt The movable rotating clamp body rotates around the pin on the rotating seat, and the torsion spring on the pin is compressed, while the fixed clamp body and the rotating clamp body open, the fixed clamp body and the rotating clamp body are aligned with the affected part, and the pulling ring is released, so that the rotating clamp body clamps the patient's affected part under the action of the torsion spring and the fixed clamp body to stop the bleeding of the patient. However, due to the use of a single-turn operating clamp body in conjunction with the fixed clamp body to stop the bleeding of the patient's affected part, it cannot be applied to hemostasis operations on affected parts in different states, and its operability is limited, and its practicality is low.

[0004] Secondly, there is a lack of easily replaceable silicone pads on the surface of the expansion block that expands the patient's uterine cavity. If the silicone pads cannot be replaced after long-term use and the surface is worn, it will cause unnecessary damage and infection to the uterine cavity. The safety of use is low and urgently needs to be developed. Utility Model Content
