Example one

Referring to fig. 1, 3 and 4, the present invention provides a hemostatic device for vascular surgery, which comprises a tourniquet 1; the first end of the tourniquet 1 is connected with a tourniquet buckle 7, and the second end of the tourniquet 1 is detachably connected with the tourniquet buckle 7; the tourniquet buckle 7 is provided with a furling mechanism 6 for tightening the tourniquet 1.

The vascular surgery hemostasis device is further improved as follows:

the tourniquet buckle 7 comprises a shell 5; the furling mechanism 6 is rotatably arranged in the inner cavity 13 of the shell 5; the shell 5 is provided with a first opening communicated with the inner cavity 13, and the first end of the tourniquet 1 passes through the first opening and is connected with the furling mechanism 6. Specifically, the furling mechanism 6 comprises a rotating rod 11 which is threaded on the shell 5; the rotating rod 11 is provided with a sliding groove, and the length direction of the sliding groove is arranged along the axis of the rotating rod 11; a rotating sleeve 12 is sleeved outside the rotating rod 11, and the rotating sleeve 12 is positioned in the inner cavity 13; a clamping strip inserted into the sliding groove is fixed on the inner wall of the rotating sleeve 12 and forms sliding fit with the sliding groove; the outer wall of the rotating sleeve 12 is fixedly connected with the first end of the tourniquet 1.

In addition, the sliding grooves are provided with a plurality of channels, and the plurality of sliding grooves are uniformly arranged at intervals along the circumferential direction of the section of the rotating rod 11; the clamping strips are matched with the sliding grooves and are provided with a plurality of strips, as shown in figure 4. And, the first end of dwang 11 is connected with the hand wheel 10, and the hand wheel 10 is located one side of casing 5.

The staff pulls dwang 11 through hand wheel 10 and rotates, changes cover 12 and rotates with dwang 11 synchronization owing to receive the restriction of card strip, spout, changes cover 12 and rotate in the operation that tourniquet 1 can tighten up tourniquet 1 and wrap the wound. Because the rotating rod 11 is in threaded connection with the shell 5, when the rotating rod 11 is pulled to rotate, the rotating rod 11 can move forwards or backwards; however, the rotating sleeve 12 is in sliding fit with the sliding chute, and the rotating sleeve 12 is always limited by the inner wall of the shell 5 and cannot move when being positioned in the inner cavity 13; therefore, the tourniquet 1 does not deviate or become skewed by the movement of the rotation lever 11. After the rotating sleeve 12 tightens the tourniquet 1, the tourniquet 1 cannot pull the rotating rod 11 to rotate reversely to loosen the tourniquet 1 due to the self-locking of the threads of the rotating rod 11 and the existence of static friction force.

The second end of the tourniquet 1 is connected with the tourniquet buckle 7 in a magic tape adhesion mode; the tourniquet buckle 7 is fixed with the guide belt 2.

In the technical scheme, the hemostatic cotton patch 8 is further included; the hemostatic cotton patch 8 is pasted on the inner side of the tourniquet 1, and the hemostatic cotton patch 8 is used for wrapping the wound when the tourniquet 1 is tightened. When the wound is bandaged, the hemostatic cotton patch 8 is firstly pasted on the wound, or the position corresponding to the wound is pasted on the inner side of the tourniquet 1. Thereafter, the tourniquet 1 is pulled around the body part (e.g. arm, wrist, thigh, calf, etc.) where the wound is located for a circle, and the second end of the tourniquet 1 is adhered to the leader 2. Then, the hand wheel 10 is pulled to enable the rotating sleeve 12 to rotate slowly to tighten the tourniquet 1 until the force for pressing the wound is moderate, and then the dressing is completed. After that, the hand wheel 10 can be pulled when people press, the tourniquet 1 is loosened or tightened, and the tourniquet 1 is prevented from being pressed for a long time.

Finally, to improve the comfort of the tourniquet buckle 7 in contact with the body surface. An arc plate 4 is arranged at the bottom of the shell 5 of the tourniquet buckle 7. And a buffer layer 3 is adhered outside the arc plate 4, and the buffer layer 3 can be directly contacted with the skin to relieve the uncomfortable feeling of compression. The buffer layer 3 may be connected to the leader 2 and formed as an integral structure. Simultaneously in order to improve the stability that tourniquet 1 wrapped, need tourniquet 1 to have certain pretightning force when taut wrapping to make tourniquet 1 not drop, can set up to the elastic band with connecing area 2, tourniquet 1.
