When the hemostatic clamp 4 needs to be clamped by the clamp applier 5, the first clamp arm 51 and the second clamp arm 52 of the clamp applier 5 are driven to be close to each other, so that the angle between the first clamp arm 51 and the second clamp arm 52 reaches a certain value, then the clamp applier 5 is inserted into the installation space 1a, the hemostatic clamp 4 is pushed to slide into the space between the first clamp arm 51 and the second clamp arm 52 under the action of the elastic force of the elastic component 3, and the two protrusions 43 of the hemostatic clamp 4 are respectively clamped in the two second clamping grooves 52a, so that the clamp applier 5 clamps the hemostatic clamp 4.

As shown in fig. 8, in one embodiment, a guide groove 51a is formed on a side of the first clamp arm 51 opposite to the second clamp arm 52, and the first clamp arm 51 can be slidably sleeved with the first clamp arm 41 or the second clamp arm 42 through the guide groove 51 a.

When the hemostatic clamp 4 is clamped by the clip applier 5, the clip applier 5 is inserted into the installation space 1a, and the first clamp arm 51 can be slidably sleeved on the first clamp arm 41 or the second clamp arm 42 through the guide groove 51a, so that the first clamp arm 51 can be close to the corresponding protrusion 43 and clamp one protrusion 43, and then the other protrusion 43 is clamped with the second clamping groove 52a of the second clamp arm 52 under the pushing of the elastic force of the elastic component 3.

The present utility model is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present utility model are intended to be included in the scope of the present utility model.
