AI Technical Summary
During use, existing vascular forceps can easily cause the hose to detach or fall into the tissue in the knife edge, and excessive clamping force can easily cause blood vessel wall indentation, affecting postoperative recovery.
A vascular forceps are designed, which includes two semi-mold bodies, and two clamping positions on the head of the forceps have two clamping positions. The hinge structure realizes segmented hemostasis, reduces the compression force on the blood vessels, and a guide part and a connection part are provided on the head of the forceps to improve the anti-slip and anti-detachment performance of the rubber sleeve.
The vascular forceps reduce the compression force on the blood vessels through segmented hemostasis, alleviate the risk of blood vessel indentation and compression, and at the same time improve the anti-slip and anti-detachment performance of the rubber sleeve, reducing medical risks.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of surgical instruments and relates to a hemostatic forceps. Background Art
[0002] A hemostatic forceps, also called a haemostat, is a surgical instrument that achieves blood blockage by clamping blood vessels. During a surgical operation, when a patient is bleeding and has taken a hemostatic drug, the hemostatic forceps is used to clamp the large blood vessel to stop bleeding so as to perform the surgical operation.
[0003] The clamping part of the existing hemostatic forceps is two strip-shaped clamp heads. Since the hemostatic forceps itself is made of metal, in order to reduce the damage to blood vessels caused by clamping, generally a rubber tube is sleeved on each of the two clamp heads. However, in the process of using such a hemostatic forceps, the rubber tube is likely to come off, and it is also very easy for the rubber tube to fall into the tissue in the incision to form a surgical risk. In addition, the existing hemostatic forceps only clamps the blood vessel once, and a relatively large clamping force is required to achieve a good hemostatic effect. However, a relatively large clamping force is likely to cause a large indentation on the blood vessel wall, which is not conducive to rapid postoperative recovery. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a hemostatic forceps aiming at the above problems existing in the prior art. The technical problem to be solved by the utility model is how to reduce the clamping strength of the hemostatic forceps on the blood vessel.
[0005] The purpose of the utility model can be achieved by the following technical solutions: A hemostatic forceps, characterized in that it includes two half forceps bodies. The half forceps body includes a handle and a clamp head. The middle parts of the two half forceps bodies are hinged. The clamp head includes a body and an arch part located in the middle of the body. A through hole is formed between the arch part and the middle part of the body. The body has a guiding part located at the front end of the arch part and a connecting part located at the rear end of the arch part. The hinged position of the two half forceps bodies is located at the connecting part.
[0006] Further, the handle is provided with a positioning rack.
[0007] In this solution, there are two clamping positions for clamping blood vessels, that is, the body and the arch part on the clamp head clamp the blood vessel at two positions. Different from the traditional hemostatic forceps, it can complete the blood vessel hemostasis function in segments, so that the clamping strength of a single position on the blood vessel is weaker than that of the traditional hemostatic forceps, that is, it reduces the pressing force of clamping hemostasis on the blood vessel, alleviates the blood vessel indentation and possible pressure injuries. In addition, in this solution, the existence of the arch part can play a better role in preventing the rubber sleeve from slipping and coming off when the rubber sleeve is sleeved on the clamp head, so that the rubber sleeve is not easily accidentally detached to cause medical risks. Brief Description of the Drawings
[0008] Figure 1 It is a structural schematic diagram of this hemostatic forceps.
[0009] Figure 2 It is a side view of the vascular forceps after the rubber sleeve is sleeved.
[0010] Figure 3 It is a side view of the vascular forceps without the rubber sleeve sleeved.
[0011] In the figure, 1 is a half forceps body; 2 is a handle; 3 is a forceps head; 4 is an arch part; 5 is a through hole; 6 is a guiding part; 7 is a connecting part; 8 is a positioning rack. Specific embodiments
[0012] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.
[0013] As Figure 1 and Figure 3 shown, the vascular forceps include two half forceps bodies 1. The half forceps body 1 includes a handle 2 and a forceps head 3. The middle parts of the two half forceps bodies 1 are hinged. The forceps head 3 includes a body and an arch part 4 located in the middle of the body. A through hole 5 is formed between the arch part 4 and the middle of the body. The body has a guiding part 6 at the front end of the arch part 4 and a connecting part 7 at the rear end of the arch part 4. The guiding part 6 is slightly bent to facilitate insertion into the clamping position. The hinged position of the two half forceps bodies 1 is located at the connecting part 7.
[0014] The handle 2 has a positioning rack 8 to achieve the locking of the clamping state.
[0015] In this solution, there are two clamping positions for the part used to clamp blood vessels, that is, the body and the arch part 4 on the forceps head 3 clamp the blood vessels at two positions, forming two parallel clamping areas with an annular structure in the middle. Note that the formed ring is not a circular ring, but a structure where the arch part is above the straight area of the body. In this way, the arch part can face upwards during operation, and the forceps head does not require a large operation space in the tissue due to the existence of the arch part. Different from traditional vascular forceps, it can complete the blood vessel hemostasis function in segments, making the clamping strength of a single position on the blood vessel weaker than that of traditional vascular forceps, that is, reducing the pressing force on the blood vessel during clamping hemostasis, alleviating the blood vessel indentation and possible pressure injuries. In addition, due to the existence of the arch part 4 in this solution, after the rubber tube is sleeved, as Figure 2 shown, it can play a better anti-slip and anti-detachment role for the rubber sleeve sleeved on the forceps head 3, making the rubber sleeve not easily detach by mistake and causing medical risks. The rubber sleeve is soft and easy to deform, and two clamping positions are still formed during clamping after the rubber sleeve is sleeved.
[0016] The specific embodiments described herein are only illustrative of the spirit of the present invention. Those skilled in the technical field to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
