DETAILED DESCRIPTION

[0033] The present application will be further described in detail below with reference to the accompanying drawings.

[0034] Embodiment one:

[0035] Referring to Figure 1 The embodiment discloses an adjustable hemostatic clamp, which comprises a first clamp body 1 and a second clamp body 2 connected in rotation, and an elastic element 21 arranged between the first clamp body 1 and the second clamp body 2. The two ends of the elastic element 21 abut against the first clamp body 1 and the second clamp body 2 respectively. The elastic force of the elastic element 21 enables the first clamp body 1 and the second clamp body 2 to clamp a human body. The elastic element 21 can be in various forms such as a metal rod, a spring, a spring sheet and the like.

[0036] Referring to Figure 1 And Figure 2 The first clamp body 1 is provided with a sliding groove 11 along the length direction of the first clamp body 1. The sliding groove 11 penetrates through the first clamp body 1. A sliding block 3 is arranged in the sliding groove 11 in sliding mode. Specifically, a guide groove 12 is arranged in the groove wall of the sliding groove 11. The extension direction of the guide groove 12 is consistent with the sliding groove 11. A guide block 31 is fixed to the side wall of the sliding block 3. The guide block 31 is connected with the guide groove 12 in sliding mode. The guide block 31 is limited in the guide groove 12, which avoids the disconnection of the sliding block 3 and the sliding groove 11 and improves the sliding stability of the sliding block 3.

[0037] A regulating rod 4 is threadedly connected to the sliding block 3. A pressing block 41 is rotatably arranged at the end of the regulating rod 4 between the first clamp body 1 and the second clamp body 2. The pressing block 41 is used for pressing the bleeding part of the human body. The pressing block 41 is made of transparent silica gel material, which can prevent slipping and facilitate the observation of whether the pressing part bleeds. A handle 42 is fixed to the end of the regulating rod 4 away from the pressing block 41. The handle 42 drives the rotation of the regulating rod 4.

[0038] The inside of the second clamp body 2, which is used for contacting the human body, is provided with a silica gel pad 22. The silica gel pad 22 contacts the back side of the pressing part of the human body, which is more skin-friendly and improves the comfort.

[0039] The implementation principle of the adjustable hemostatic clamp is as follows: the first clamp body 1 and the second clamp body 2 clamp the human body. The sliding block 3 is slid to the bleeding part. The regulating rod 4 is rotated by the handle 42. The regulating rod 4 is connected with the sliding block 3 in thread mode, which enables the pressing block 41 to approach and press the bleeding part, thereby achieving the hemostatic effect. The rotation of the regulating rod 4 can adjust the distance and pressing force of the pressing block 41 to the bleeding part. The sliding of the sliding block 3 can adjust the position of the pressing block 41 relative to the human body. The pressing block 41 can be adjusted to a suitable position without re-clamping, which is more convenient and avoids the discomfort of the patient caused by the poor position of the hemostatic clamp.

[0040] The reaction force of the pressing acts on the sliding block 3, which enables the guide block 31 to be pressed in the guide groove 12. The friction force avoids the spontaneous sliding of the sliding block 3. The friction force also exists between the pressing block 41 and the human body. Therefore, the sliding block 3 of the embodiment is not easy to slide spontaneously, which can meet the use requirements.

[0041] Embodiment two:

[0042] Referring to Figure 3 and Figure 4 The adjustable hemostatic clamp of the second embodiment differs from the first embodiment in that a tooth groove 13 is formed along the length of the clamp body 1, and the sliding block 3 is fixed with a clamping tooth 32 that cooperates with the tooth groove 13, and the thickness of the guide block 31 is less than the internal height of the guide groove 12.

[0043] The principle of the second embodiment is that the thickness of the guide block 31 is less than the internal height of the guide groove 12, so that the guide block 31 can be displaced in the thickness direction within the guide groove 12, that is, the sliding block 3 can be moved towards or away from the clamp body 2. After the sliding block 3 is moved towards the clamp body 2, the clamping tooth 32 is disengaged from the tooth groove 13, and the sliding block 3 can be smoothly slid along the sliding groove 11, so as to adjust the pressing position. When the adjusting rod 4 is rotated for pressing, the reaction force drives the sliding block 3 to move away from the clamp body 2, so that the clamping tooth 32 is inserted into the clamping groove, thereby avoiding the sliding block 3 from sliding along the sliding groove 11, and improving the position stability of the sliding block 3 in the pressing state.

[0044] Embodiment three:

[0045] Referring to Figure 5 The adjustable hemostatic clamp of the third embodiment differs from the first embodiment in that a magnetic member 14 is fixed to the clamp body 1, and the sliding block 3 is fixed with a magnetic member 33 that is attracted to the magnetic member 14.

[0046] The magnetic member 14 is arranged in a long strip shape along the length direction of the sliding groove 11. When the magnetic member 14 is an iron sheet, the magnetic member 33 is a magnet. The materials of the two can also be interchanged, that is, when the magnetic member 14 is a magnetic strip, the magnetic member 33 is an iron block. In another embodiment, the magnetic member 14 and the magnetic member 33 are both magnets, and the mutually close faces of the magnetic member 14 and the magnetic member 33 are arranged to be attracted to each other.

[0047] Through the magnetic attraction of the magnetic member 14 and the magnetic member 33, the resistance of the sliding block 3 to slide along the sliding groove 11 is improved, thereby avoiding the sliding block from sliding spontaneously along the sliding groove 11, and improving the position stability of the sliding block 3 in the pressing state.

[0048] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
