Description

Technical Field

[0001] The utility model relates to the technical field of gynecological and obstetric surgery, in particular to a uterine cavity hemostat for gynecological and obstetric surgery. Background Art

[0002] Obstetrics and gynecology is one of the four major disciplines in clinical medicine. It focuses on the etiology, pathology, diagnosis, and prevention of female reproductive organ diseases, the physiological and pathological changes of pregnancy and childbirth, the prevention and treatment of high-risk pregnancies and dystocia, female reproductive endocrinology, family planning, and women's health. Hemostat is a surgical instrument that clamps blood vessels to block blood flow. In emergency situations involving bleeding, after administering hemostatic medication, hemostat is used to clamp a large artery to prevent bleeding. Hemostats work similarly to clamps, but they are sterilized. Hemostats come in various sizes, with or without teeth, and in straight or curved shapes. Different types of hemostat are used depending on the area of ​​operation. The teeth on the side of the hemostat handle help secure the clamp and prevent it from falling off.

[0003] Currently, hemostatic forceps are also used in gynecological surgeries. When performing surgery on the patient's uterine cavity, since the uterine cavity is inside the body, the length of the hemostatic forceps in the existing technology cannot be adjusted, which may affect the hemostasis of the uterine cavity due to the short length of the hemostatic forceps. In addition, if the existing hemostatic forceps can be assisted by drugs when stopping bleeding in the uterine cavity, the hemostatic effect will be improved. Therefore, there is an urgent need to develop a uterine cavity hemostatic forceps for clinical obstetrics and gynecology. Utility Model Content

[0004] In view of the defects in the existing technology, the purpose of the present invention is to provide a uterine cavity hemostat for obstetrics and gynecology surgery, which is convenient for rapid hemostasis operation at the bleeding site of the uterine cavity and significantly improves the hemostasis effect.

DETAILED DESCRIPTION

[0021] The following embodiments of the technical solution of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0022] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which this utility model belongs.

[0023] like Figures 1 to 3 As shown, a specific embodiment of the present invention provides a uterine cavity hemostat for obstetrics and gynecology surgery, comprising a pair of forceps rods 100, the two forceps rods 100 are hingedly connected by a rotating shaft, a hemostatic head 200 is provided at the front end of the two forceps rods 100, and an anti-slip layer 300 is provided on the opposite sides of the two hemostatic heads 200, the surface of the anti-slip layer 300 is provided with spaced clamping protrusions 310, the clamping protrusions 310 provided on the anti-slip layer 300 of the two hemostatic heads 200 are staggered with each other, and a forceps handle 400 is slidably covered on the rear end of the forceps rod 100, one of the forceps handles 400 is provided with a drug delivery tube 500, one end of the drug delivery tube 500 is connected to an elastic hemostatic drug bag 600, and the other end is communicated with a drug delivery hole 700 provided on the side of the hemostatic head 200.

[0024] like Figures 1 to 3As shown, through the above-mentioned arrangement, the hemostat in this embodiment adopts a clamp structure and utilizes the hemostatic head 200 to clamp the bleeding position when in use. The anti-slip layer 300 provided on the hemostatic head 200 is provided with staggered clamping protrusions 310, which can ensure the clamping and hemostasis effect of the bleeding position; at the same time, when in use, the clamp rod 100 can be slid according to the hemostatic position, thereby adjusting the protruding length of the clamp rod 100 relative to the clamp handle 400.

[0025] like Figures 1 to 3 As shown, since the hemostatic head 200 is connected to the hemostatic drug bag 600 through the dosing tube 500, the hemostatic drug stored in the hemostatic drug bag 600 is output from the dosing hole 700 through pressure. The bleeding site after clamping hemostasis can improve the hemostatic effect under the action of the hemostatic drug, accelerate the hemostasis efficiency, and facilitate rapid hemostasis for the patient.

[0026] like Figures 1 to 3 As shown, this embodiment includes an arc-shaped return spring 800 between the two handles 400. Both ends of the return spring 800 are connected to the corresponding handle 400. The provision of the return spring 800 provides the hemostatic forceps with a return mechanism. Once the hemostatic operation is complete, the handles 400 automatically expand to release the hemostatic area.

[0027] like Figures 1 to 3 As shown, to facilitate the placement of hemostatic drugs into the hemostatic drug capsule 600 by medical personnel, this embodiment provides a drug hole 610 on the surface of the hemostatic drug capsule 600, with a removable cover. This allows medical personnel to place the drug into the hemostatic drug capsule 600 using a syringe or other tool, and then squeeze the hemostatic drug capsule 600 to deliver the drug to the drug delivery hole 700. Furthermore, each drug delivery hole 700 of the hemostatic head 200 is provided with a one-way valve flap 1100 at the opening. The one-way valve flap 1100 can be opened under pressure to allow the hemostatic drug to be fully delivered to the hemostatic site.

[0028] like Figures 1 to 3 As shown, the hemostatic forceps need to be handheld during use. To improve hand-holding stability, this embodiment has a grip ring 900 on the end of the handle 400 away from the rod 100. The grip ring 900 is covered with a non-slip cover. This facilitates hand-holding by medical personnel. Because the rod 100 can slide relative to the handle 400 to adjust the length of the hemostatic head 200, a pre-tightening screw 1000 is threaded onto the handle 400 in this embodiment to fix the relative position of the rod 100 and the handle 400. The pre-tightening screw 1000 can secure the handle 400 after the length adjustment is completed, ensuring operational stability.

[0029] like Figures 1 to 3As shown, this embodiment features a threaded interface at the front end of the clamp rod 100. The hemostatic head 200, near the end of the clamp rod 100, is equipped with a connector 210 that mates with the threaded interface. In other words, the hemostatic head 200 can be mounted on the front end of the clamp rod 100 via the connector 210, enabling detachable installation. In this embodiment, a drug delivery connector 211 is provided at the end of the connector 210, which plugs into and connects to the drug delivery tube 500. A drug delivery cavity is provided within the hemostatic head 200, communicating with the connector 211 and further communicating with the drug delivery port 700. This allows the connector 211 to communicate with the drug delivery tube 500, thereby delivering the hemostatic drug from the hemostatic capsule 600 to the drug delivery port 700. To allow the drug delivery tube 500 to pass through the clamp rod 100 and connect to the hemostatic head 200, this embodiment features a mounting channel within the clamp rod 100 for the drug delivery tube 500 to pass through. After passing through the mounting channel, the end of the drug delivery tube 500 connects to the connector 211. In actual application, the drug delivery tube and drug bag structure adopt a disposable silicone structure, which is convenient for disinfecting the entire hemostatic forceps after use.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
