[0042] Reference Figures 1 to 10 , a utility model embodiment a closure clamp, including closure clamp body 100, the closure clamp body 100 is V-shaped, including plastic hinge 200, the plastic hinge 200 is provided with small window 300 and through hole 310, the through hole 310 is arranged at the converging of both ends of the small window 300.

[0043] The closure clip body 100 comprises a first clip group 110 and a second clip group 120, the plastic hinge 200 is arranged between the first clip group 110 and the second clip group 120, the first clip group 110 is curved outward away from the plastic hinge 200, and the second clip group 120 is curved inward away from the plastic hinge 200.

[0044] The plastic hinge 200 comprises an outer plastic hinge 210 and an inner plastic hinge 220, the inner plastic hinge 220 is provided with a bending part 2210, the small window 300 is arranged between the outer plastic hinge 210 and the inner plastic hinge 220, and the through hole 310 is arranged at both ends of the small window 300 and symmetrically arranged about the highest point of the bending part 2210.

[0045] The through hole 310 is circular.

[0046] The inner sides of the first clip group 110 and the second clip group 120 are provided with anti-skid teeth 400.

[0047] The first clip group 110 is provided with a lock catch 500, the second clip group 120 is provided with a lock slot 510, and the lock catch 500 and the lock slot 510 are clamped.

[0048] In the embodiment of the application, the closure clip is in V shape, and the closure clip comprises a plastic hinge 200, a first clip group 110 and a second clip group 120. The plastic hinge 200 is located between the first clip group 110 and the second clip group 120, and the plastic hinge 200 is a bending part on the closure clip. The first clip group 110 is curved outward as a parabola away from the plastic hinge 200, and the second clip group 120 is curved inward away from the plastic hinge 200. The plastic hinge 200 comprises an outer plastic hinge 210 and an inner plastic hinge 220. A small window 300 in the shape of a crescent is arranged between the outer plastic hinge 210 and the inner plastic hinge 220. In this embodiment, the through hole 310 is a circular through hole 310. The purpose of the design is to eliminate the stress concentration of the plastic hinge 200 when the closure clip is closed. The first clip group 110 is provided with a first protrusion 1101, and the second clip group 120 is provided with a second protrusion 1201, which is used to adapt to the jaw of the clip applier. The inner sides of the first clip group 110 and the second clip group 120 are provided with a plurality of anti-skid teeth 400, which is used to increase the friction between the patient's tissue or lumen and the inner side of the closure clip, prevent the migration of the closure clip in the patient's lumen, and reduce the risk of the closure clip not tightly clamping the tissue or lumen. The V-shaped two sides of the closure clip, i.e. the first clip group 110 and the second clip group 120, are provided with a lock catch 500 and a lock slot 510. The lock catch 500 and the lock slot 510 can be fastened when the clip applier is engaged.

[0049] Specifically, when the lock catch 500 of the closure clip starts to contact and close with the lock slot 510, the clip body on the side of the lock slot 510 will be laterally offset relative to the end clip body of the lock catch 500, causing the plastic hinge 200 to be prone to tensile deformation. When the plastic deformation exceeds the elastic stage and yield stage of the material itself, the material undergoes irreversible damage, which will cause the closing force of the closure clip to weaken, and at the same time, increase the risk of rupture on the inside and outside of the plastic hinge 200. The reason is that, on the one hand, during the closing process of the closure clip, the plastic hinge on the inside of the small window 300 has too large a bending angle, which is prone to material rupture. On the other hand, although the plastic hinge on the outside of the small window 300 has sufficient strength and is not prone to rupture, since the small window 300 is in the shape of a crescent, when the plastic hinge on the inside of the small window 300 deforms, it will cause a circumferential force at both ends of the crescent, causing a large plastic deformation at both ends of the crescent, which is prone to material rupture on the outside of the plastic hinge 200. Therefore, the present application is provided with a bending portion 2210 on the inside of the plastic hinge 200, so that when the closure clip is closed, the inside of the plastic hinge 200 follows the closure, and the inside of the plastic hinge 200 will not be subjected to stress concentration to cause plastic cracking. The circular through hole 310 is provided at both ends of the small window 300, and when the closure clip is closed, the outside of the plastic hinge 200 follows the closure, and the outside of the plastic hinge 200 and both ends of the small window 300 will not be subjected to stress concentration to cause plastic cracking, thereby increasing the two features of the bending portion 2210 and the circular through hole 310. Since the thickness of the outside of the plastic hinge 200 does not change, the closing force of the closure clip is not reduced. The design of the present application reduces the risk of injury to the patient during the operation process and after implantation, and increases the clinical benefit.

[0050] In another embodiment, the through hole 310 can be designed as an elliptical through hole 310, a rectangular through hole 310, a long strip-shaped through hole 310, and a polygonal through hole 310, etc. in addition to being designed as a circular through hole 310. When it is an elliptical through hole 310, the elliptical through hole 310 can provide greater flexibility in one direction, which helps to reduce stress concentration in a specific direction. Compared with the circular through hole 310, the ellipse has different sizes in the two principal axes directions, which can provide better adaptability in a specific direction and is suitable for applications that need to bear more stress in a specific direction. When it is a rectangular through hole 310, the rectangular through hole 310 can provide structural rigidity while allowing more bending in the long direction, which helps to reduce stress and is suitable for situations that need to provide more flexibility in a specific plane. The long strip-shaped through hole 310 can provide the greatest flexibility, which helps to reduce stress concentration when the closure clip is bent, and is suitable for applications that require high flexibility and stress release. The polygonal through hole 310 (such as a triangle, a hexagon, etc.), which can be optimized according to the specific design and stress distribution of the closure clip to provide specific mechanical properties, is suitable for applications that require specific mechanical properties or stress distribution optimization.
