Improves the use flexibility

In order to facilitate the one-hand operation, in a preferred embodiment, the tail end of the piston rod 2 is provided with a pull ring 4; the operating handle 5 is provided with a bracelet 6. During operation, the thumb and the middle finger are respectively inserted into the two hand rings 6 to control the opening and closing of the jaws, and the index finger or the ring finger can be inserted into the pull ring 4 to control the movement of the piston. The convenience of one-hand operation is improved, and the push-pull action of the piston can be realized while the opening and closing of the jaw is realized by one-hand operation.

In order to improve the use stability of the product, in a preferred embodiment, the barrel 1 is provided with a limit ring 16; the stop collar 16 is located at the rear end of the first slider 8. The stop collar 16 limits the travel of the first slide, preventing it from moving excessively due to an operational error, which could lead to product errors.

The working principle of the invention is as follows:

as shown in fig. 1-2, when a hemostatic operation needs to be performed, when the two operating handles 5 are controlled to be closed, the two movable rods 7 are driven to be closed, the movable rods 7 push the first sliding member 10 to move forward on the cylinder 1, so as to drive the second sliding member 10 to move forward, and the second sliding member 10 drives the two movable rods 11 to move forward, so that the clamp portion 12 is closed to clamp a blood vessel to perform hemostasis.

When medicine is added while hemostasis is needed, the medicine can be placed in the barrel body 1 in advance, when the blood vessel is clamped through the clamp part 12, the piston rod 2 is pushed to drive the piston 3 to move forwards, and the hemostatic medicine is injected into the clamp mouth from the needle tube 13 and is contacted with the blood vessel, so that hemostasis of the blood vessel is promoted.

When the excessive blood at the operation position needs to be removed, the blood vessel is clamped through the clamp part, the piston rod 2 is pulled outwards, and the blood which flows out from the wound and affects the sight of the doctor is sucked into the barrel body 1 through the needle tube 13. Can achieve the effects of removing redundant blood and accelerating blood coagulation.

As shown in fig. 3-4, when the two operating handles 5 are controlled to be closed, the two movable rods 7 are driven to be closed, the movable rods 7 push the first sliding part 10 to move forward on the cylinder 1, so as to drive the second sliding part 10 to move forward, and the second sliding part 10 drives the two movable rods 11 to move forward, so that the forceps part 12 is closed to clamp the blood vessel to achieve hemostasis; meanwhile, when the first sliding part 10 moves forwards on the barrel 1, the first sliding part abuts against the adjusting nut 23 through the connecting part 24 at the tail end, so that the piston rod is controlled to be pushed forwards, and the medicine is automatically conveyed out of the needle tube. In order to control the amount of drug delivered, the adjustment nut 23 may be rotated beforehand, the smaller the amount of drug delivered when the adjustment nut 23 is biased towards the front end position of the piston rod, and the larger the amount of drug delivered when the adjustment nut 23 is biased towards the rear end position of the piston rod.
