When the clamping force of the single clamp 2 is 80-120g / mm², it is suitable for clamping veins of 5-10mm.

[0047] Example 6

[0048] Reference Figure 1~Figure 5 Compared with Example 1, further, the clamping portion 5 has a plurality of protrusions 6, the plurality of protrusions 6 are distributed at intervals, the protrusions 6 are in the shape of a trapezoid, the bottom surface of the trapezoid is a square, the side length of the square is 0.2-0.4 mm, and the protrusions 6 on the two clamping portions 5 are arranged to bite into each other.

[0049] In this embodiment, in order to better clamp the blood vessel and prevent the blood vessel from slipping and deviating, a protrusion 6 is provided on the clamping portion 5, which is in the shape of a trapezoid with rounded corners. The protrusions 6 on the two clamping bodies 3 can bite each other up and down, and the staggered protrusions 6 can reduce the slipping and deviation of the blood vessel.

[0050] Example 7

[0051] Reference Figure 1~Figure 5 Compared with the embodiment 1, the clamp body 3 further has a pressing portion 7, the pressing portion 7 has an inner groove 8, and the inner groove 8 has an anti-slip protrusion 9.

[0052] In this embodiment, a pressing portion 7 is provided for ease of use. The inner groove 8 on the pressing portion 7 is configured to be in a shape suitable for fingers, and there is also an anti-slip protrusion 9 therein, which makes it more convenient to use.

[0053] Example 8

[0054] Reference Figure 1~Figure 5 Compared with Example 1, further, the single clamp 2 has one, and the clamp body 3 also has a hinge hole 10, wherein the cross section of the hinge hole 10 of one clamp body 3 is circular or non-circular, and the cross section of the connecting member 1 is consistent therewith, and the cross section of the hinge hole 10 of the other clamp body 3 is circular.

[0056] The hemostatic clip in this embodiment can be used as a single clip or a double clip. Specifically, when it is a single clip, the connecting member 1 can be a sleeve, and the cross-sections of the hinge hole 10 and the sleeve are both circular, and both clamp bodies 3 can rotate around the sleeve. Alternatively, the cross-sections of one of the hinge holes 10 and the sleeve can be non-circular, such as fan-shaped, rectangular, etc., and the cross-section of the other hinge hole 10 can be circular. In this way, one clamp body 3 cannot rotate around the sleeve, and the other clamp body 3 can rotate around the sleeve, and it does not affect the use of the hemostatic clip.

[0057] When there are two single clamps 2, the cross-section of the connecting piece 1 is non-circular, which may be fan-shaped, semicircular, rectangular, etc., so that one clamp body 3 does not rotate around the connecting piece 1, while the other clamp body 3 can rotate around the connecting piece 1, thereby preventing the single clamp 2 from twisting along the connecting piece 1 as a whole, facilitating the use and operation of the hemostatic clamp, avoiding twisting and deformation of the blood vessel, and ensuring the surgical effect.

[0058] The specific structure of the hemostatic clamp is as follows: the connecting piece 1 can adopt a hinge shaft, the hinge hole of one clamp body 3 is on the inner side of the hinge holes of two clamp bodies 3, the hinge shaft passes through in sequence, the torsion spring 4 is placed on the inner side of the two clamp bodies 3, and the middle part thereof is aligned with the hinge hole 10 and the hinge hole 2 11.
