It should be noted that the distal side is defined as the side near the muscle tissue and away from the body of the doctor; proximal defines the side of the body that is closer to the physician, away from the musculature. The distal end is defined as the distal end position; the proximal end is a proximal end position.

In addition, it should be noted that, as an example, as shown in fig. 1, the handle portion is a one-component assembly, and may include all or a part of the whole structure in fig. 1, which is not limited in this application. In addition, it should be noted that, as an example, as shown in fig. 2, the clamping arm portion is a component assembly, including all or a part of the whole structure in fig. 2, and the application is not limited thereto.

In the above technical solution, when the tissue around the wound and the bleeding blood vessel are clamped and closed, since the number of the movable clamping arms 202 is plural and the number of the handles 100 is plural, each handle 100 can independently control the opening and closing of the corresponding movable clamping arm 202 and the corresponding fixed clamping arm 201 through the linkage part, when the wound is large, the hemostatic clamp can also be applied, and the hemostatic purpose is achieved. In addition, in this kind of technical scheme, through increasing handle 100 and the corresponding quantity of movable clamping arm 202, therefore also simple structure, manufacturing cost is also lower.

To sum up, the hemostatic clamp that this application provided can realize that the clamp of great wound is closed fixedly, reaches hemostatic purpose to simple structure, the cost is lower.

In the above technical solution, further improvements can be made. For example, as shown in fig. 4, the linkage component is a slider 101, and the slider 101 can be movably sleeved outside the circumference of the handle 100, so as to drive the movable clamping arm 202 to open and close with the fixed clamping arm 201 along with the movement of the slider 101. Specifically, the handle 100 includes a stem 102, and the slider 101 is movably sleeved on the outside of the stem 102. In this type of solution, when the wound is pinched, the slider 101 slides by hand, and then the slider 101 transmits the driving force to the fixed clip arm 201 and the movable clip arm 202 through a certain connecting member, so that the opening and closing of the clip arms can be very easily achieved.

Further, as shown in fig. 4, the number of the handles 100 may be two, and may be Y-shaped; the number of the sliding blocks 101 is two, and the number of the movable clamping arms 202 is two; the two movable clamping arms 202 are respectively arranged at two sides of the fixed clamping arm 201.

On the basis of being held by a human hand, the sliding block 101 is convenient to drive to slide.

Further, in the above structure, a specific design may be made. For example, the two handles 100 may be integrally formed components. The integrally formed structure can facilitate the handle to form a Y-shaped structure, and when the pipe is made of hard materials, the integrally formed Y-shaped handle can also achieve the purpose of keeping the included angle between the two unchanged.

The transverse dimension of the connecting movable pin shaft 401 of the connecting rod 400 is larger than the inner diameter dimension of the fixing ring 402, when the connecting rod 400 is pulled by a steel wire rope, the connecting rod 400 moves downwards to the fixing ring 402, the fixing ring 402 is pressed downwards, and therefore the three-jaw buckle 702 is driven to move to achieve separation of the transition cap 700 and the clamp holder 500.

As shown in fig. 5, the arm part further includes a fixing cap 600 and a distal end spring tube 800, the fixing cap 600 is used for connecting the distal end spring tube 800 and an insert of the transition cap 700, the fixing cap 600 and the distal end spring tube 800 are connected through a welding process, and the fixing cap 600 and the insert of the transition cap 700 are axially restrained by a step and can move and rotate.
