A through hole is provided on the sleeve 23, and this through hole is located between the first hand-held plate 11 and the second hand-held plate 21; the positioning pin 4 can be inserted into the through hole and the lower end of the positioning pin 4 can contact the surface of the central axis 3 to limit the relative rotation between the sleeve 23 and the central axis 3, so that clamping fixation can be carried out after the first clamping plate 12 and the second clamping plate 22 clamp the wound well, and clamping fixation can be realized when the first clamping plate 12 and the second clamping plate 22 are at different angles, thereby achieving a better clamping effect when used for different individuals and treating wounds in different situations.

[0036] In this embodiment, the first hand-held plate 11 and the second hand-held plate 21 are symmetric with each other and are located on both sides above the central axis 3, the first clamping plate 12 and the second clamping plate 22 are symmetric with each other and are located on both sides below the central axis 3; the central axis 3 is parallel to both the plane where the inner wall of the first clamping plate 12 is located and the first hand-held plate 11, and the central axis 3 is parallel to both the plane where the inner wall of the second clamping plate 22 is located and the second hand-held plate 21; there are two collars 13, and the two collars 13 are located at both ends of the sleeve 23; the collar 13 and the sleeve 23 are both located between the first clip body 1 and the second clip body 2.

[0038] The plurality of first clamping needles 14 are arranged at equal intervals along a straight line, the plurality of second clamping needles 24 are arranged at equal intervals along a straight line, and the straight line where the plurality of first clamping needles 14 are located is parallel and opposite to the straight line where the plurality of second clamping needles 24 are located; thus, uniform clamping can be achieved.

[0039] Circumferentially arranged grooves are provided along the central axis 3 corresponding to the through hole, and the lower end of the positioning pin 4 can be accommodated in each groove; or in another embodiment, the circumferential surface of the central axis 3 corresponding to the through hole is an annular rough surface, and the lower end surface of the positioning pin 4 is a rough surface. In both cases, when the positioning pin is inserted into the through hole and contacts the central axis, the relative rotation between the sleeve and the central axis can be restricted, so that clamping and fixing can be carried out after the first clamping plate 12 and the second clamping plate 22 clamp the wound.

[0046] The process of first aid hemostasis of the present invention is as follows:

[0047] Take out the sterile war wound first aid hemostasis closure compression clip of the present invention that has been completely sterilized from the sealed package; in the initial state, the compression clip is in a semi-open state. Press the first hand-held plate and the second hand-held plate in the relatively inward direction to separate the first clamping plate and the second clamping plate; when the opening angle is the largest, the first clamping needle and the second clamping needle are fully exposed. At this time, control the first hand-held plate and the second hand-held plate and approach the wound to start the clamping operation; align the long axis of the compression clip, that is, the axial direction of the central axis, with the running direction of the target wound to be hemostatic, and place the whole compression clip around the wound; further, after aligning with the part to be clamped, press the first clamping plate and the second clamping plate in the relatively inward direction to slowly insert the first clamping needle and the second clamping needle into the skin around the wound, and further clamp; during the clamping process of the first clamping needle and the second clamping needle, they penetrate into the corresponding opposite rubber pads to complete the overall pressurization process; when the clamping degree is satisfactory, press the positioning pin into the through hole and contact the central axis until it is completely pressed down so that the positioning pin is completely embedded in the groove on the central axis, that is, the locking is completed. Observe whether the wound is completely clamped and covered, and further observe whether there is active exudative bleeding at the wound. When the wound is well clamped and there is no massive bleeding and the hemostasis effect is satisfactory after observation, it is considered that the implementation of part of the operation is completed. After being sent to a medical institution later, the hemostasis clip is untied in the same way and further treatment is carried out. It should be emphasized that the hemostasis closure compression clips are for single use only and should be discarded as medical consumable waste after use.
