[0002] An endoscope is a detection instrument that integrates traditional optics, ergonomics, precision machinery, modern electronics, mathematics, and software. It has an image sensor, optical lens, light source, mechanical device, etc. It can enter the stomach through the mouth or enter the body through other natural channels. Endoscopes can be used to see lesions that cannot be displayed by X-rays, so it is very useful for doctors. In clinical surgery, small clips are used to clamp the wound when stopping bleeding or suturing the patient's organ tissue. However, traditional hemostatic clips have a small clamping range and sometimes require multiple clamping treatments. It is especially difficult to operate on slightly larger tissue wounds. Some large clips cannot accurately bite the wound, which is inconvenient to use. Summary of the invention

When the anastomosis clip 5 is separated, it restores the occlusal state under the action of its own elastic force, bites the target tissue, completes the occlusal treatment, can bite a larger piece, is easy to use, and is conducive to effective hemostasis and rehabilitation of organ tissues.

[0077] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
