Description

Novel noninvasive hemostatic clamp Technical Field The application relates to the technical field of medical instruments, in particular to a novel noninvasive hemostatic clamp. Background In surgery, hemostatic clips are commonly used to temporarily block blood flow from a blood vessel, facilitating the surgical procedure or suturing. The design and quality of the hemostatic clip plays a vital role in protecting blood vessels and stopping bleeding. The existing noninvasive hemostatic clip device, such as the noninvasive hemostatic clip device disclosed in the application number CN201921766898.8, adopts a simple and effective structural design, can better realize temporary blocking of blood vessels, and has ideal hemostatic effect. However, in practical applications, the existing hemostatic clips still have some drawbacks. First, there is a risk of the partially non-invasive hemostatic clip coming loose during the fixation process. Since the hemostatic clip usually needs to exert a certain pressure during clamping, if the fixing mechanism is not stable enough during operation, the hemostatic clip may loosen or slip due to external force or movement, thereby affecting the hemostatic effect and even causing vascular injury. Secondly, the existing hemostatic clips may lack sufficient clamping force during operation, which results in failure to fully compress blood vessels or tissues, particularly in larger blood vessels or in places where clamping is difficult, which can easily cause incomplete hemostasis or unstable clamping. Disclosure of Invention The application mainly aims to provide a novel noninvasive hemostatic clamp, which aims to solve the problem that the existing hemostatic clamp is loose and affects the hemostatic effect due to the fact that the existing hemostatic clamp is not firmly fixed in practical application.
