[0026] In the following, the pincers with the attraction function according to the example embodiment will be further described.

[0027] In some embodiments of the present application, reference is made to Figure 1 Among the two pincers bodies, the first pincers body 1 is in a hollow structure and has a channel for blood circulation; the first through hole 13 in communication with the hollow structure is arranged at one end of the first pincers mouth 11 away from the hinge, the second through hole 14 in communication with the hollow structure is arranged at one end of the first pincers arm 12 away from the hinge, and the second through hole 14 is used for being connected with the negative pressure equipment; the internal channel of the first pincers body 1 forms a negative pressure suction force through the negative pressure equipment, the blood is sucked away through the first through hole 13, and thus the blood vessel can be clamped by the blood vessel clamp while the blood is sucked away, and a separate blood sucking tool is not needed. The third through hole 15 is arranged at one side of the first pincers arm 12 close to the second through hole 14 and facing the second pincers arm 22, and the third through hole 15 is used for forming or releasing the negative pressure of the internal channel of the first pincers body 1, that is, when the third through hole 15 is blocked, one end of the internal channel is in contact with the blood and the other end is connected with the negative pressure equipment, the blood can be sucked away, and when the third through hole 15 is opened, the internal channel is in communication with the external atmospheric pressure, the negative pressure cannot be formed, and thus the blood cannot be sucked. By arranging the third through hole 15 on the inner side of the first pincers arm 12 close to the end portion, the medical staff can block or open the third through hole 15 by fingers, and thus the formation of the negative pressure can be controlled, the operation is convenient, and the frequency of the blood suction can be quickly controlled. When the amount of bleeding is large, the blood is sucked, and when the amount of bleeding is small, the blood sucking can be paused for other operations.

[0028] As a preferred embodiment, the first clamp body 1 is provided with a suction tube 3, and a slot hole 31 is formed in the side wall of the suction tube 3 near the third through hole 15 and communicates with the inside of the suction tube 3. One end of the suction tube 3 extends outward through the second through hole 14 and is provided with a negative pressure interface for connecting with a negative pressure device. The suction tube 3 can also be used for blood suction by being provided in the first clamp body 1. The end of the suction tube 3 near the first through hole 13 can slightly extend outward, and the end of the suction tube 3 near the second through hole 14 also extends outward by a certain length and is provided with a negative pressure interface to better connect with the negative pressure device. By providing the suction tube 3, different suction tubes 3 can be replaced for different patients to improve the safety and hygiene. The side wall of the suction tube 3 is provided with a slot hole 31 opposite to the third through hole 15, so that the suction tube 3 can be synchronously blocked or opened with the third through hole 15.

[0029] As a preferred embodiment, referring to Figure 2 and Figure 3 , the suction tube 3 is slidably provided in the first clamp body 1, and the end of the suction tube 3 near the first through hole 13 is provided with a tapered suction disc 4 which is elastic and can be gathered to the center, and the center of the suction disc 4 is provided with a fourth through hole which communicates with the suction tube 3. By sliding the suction tube 3 in the first clamp body 1, the end of the suction tube 3 for blood suction is provided with a gatherable suction disc 4. When the suction tube 3 slides to the negative pressure device end by a certain length in the first clamp body 1, the suction disc 4 is gathered and retracted into the first clamp body 1. When the suction tube 3 slides to the blood suction end by a certain length, the suction disc 4 extends out of the first clamp body 1, and the suction disc 4 automatically expands into a disc shape under the action of the elastic force, which can expand the blood suction range and improve the blood suction efficiency when the bleeding amount is large.

[0030] As a preferred embodiment, the side wall of the suction disc 4 is provided with a plurality of suction channels 41 along the circumference thereof, the plurality of suction channels 41 converge from the edge to the center, and the plurality of suction channels 41 communicate with the fourth through hole. The structure of the suction disc 4 is similar to that of a lotus leaf, which converges from a plurality of suction channels 41 to a central channel. By simultaneously performing blood suction through the plurality of suction channels 41 and the fourth through hole, the blood suction efficiency can be greatly improved, and the blood suction area can be expanded. At the same time, since the fourth through hole is in the middle, when the suction disc 4 is not used, the suction disc 4 can be retracted into the first clamp body 1 and directly perform blood suction through the fourth through hole.

[0031] As a preferred embodiment, the suction tube 3 and the suction disc 4 are both made of medical silicone rubber material. The medical silicone rubber material has a certain elasticity, which can ensure that the suction disc 4 can be folded and gathered without harm.

[0032] As a preferred embodiment, the thickness of the portion of the suction disc 4 between two adjacent suction channels 41 is less than the thickness of the suction channel 41, so that the suction disc 4 is easy to contract and expand, and the suction channel has a certain width.

[0033] As a preferred embodiment, referring to Figure 3 The length of the slot hole 31 is greater than the axial length of the third through hole 15 on the first jaw arm 12. Since the suction disc 4 needs to move the suction tube 3 during contraction and expansion, the length of the slot hole 31 is set to be greater than the length of the third through hole 15, so that medical staff can control the negative pressure suction through the third through hole 15 whether the suction disc 4 is pushed out of the first jaw body 1 for expansion.

[0034] As a preferred embodiment, the suction tube 3 is attached to the inner wall of the first jaw body 1. Since the suction tube 3 is made of silicone rubber, attaching it to the inside of the first jaw body 1 can ensure the sealing effect of the third through hole 15, the slot hole 31 and the second through hole 14, and maintain stable negative pressure suction during blood suction.

[0035] It should be noted that the first jaw body 1 can correspond to the right hand or left hand of a person to adapt to medical staff with different hand habits.

[0036] The above is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application can be variously modified and changed. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
