A kind of microsurgical forceps that can be clamped and fixed by double forceps head

Abstract

The utility model relates to a microsurgical forceps capable of clamping and fixing double clamp heads, which belongs to the technical field of medical instruments and is used for clamping and fixing operations. Its technical solution is: the present invention adds double clamp heads that can be clamped and fixed on the basis of traditional surgical forceps. The clip at the front end of the clamp head can clamp blood vessels or nerves. There is a clamping spring between the two clips. After the clamp head clamps the blood vessel or nerve, the handles on both sides of the surgical forceps are closed, so that the clamp heads on both sides are closed in the middle, and the anastomosis of the two ends can be realized. The invention has the advantages of reasonable structure, simple and flexible operation, and firm fixation, which can reduce repeated clamping of blood vessels during operation, avoid artificial damage, and realize single-person operation of clamping, measuring, anastomosis and fixing. The invention is an innovation of microsurgical technology, which effectively avoids the disadvantages of poor anastomosis of broken ends of blood vessels and nerves in microsurgery and often requires special personnel to assist in the operation, shortens the operation time, and effectively reduces the pain of patients.

Description

technical field [0001] The invention relates to a microsurgical forceps with double forceps heads capable of clamping and fixing operations, and belongs to the technical field of medical instruments. Background technique [0002] In microsurgery, the ultimate treatment for vascular and neurological diseases or traumatic injuries is reconstruction of blood vessels or nerves by means of direct repair, patch formation or bridging, so the anastomosis and suture of blood vessels and nerves are performed by microsurgery One of the basic technologies is also the top priority. However, the blood vessel is a kind of elastic hollow tube with a smooth adventitia, while the nerve is a smooth substantive tube. The texture of the two is delicate, and damage should be avoided during the operation. However, most of the current surgical instruments are relatively bulky, and repeated clamping can easily cause irreversible damage to blood vessels and nerves. Moreover, blood vessels and nerves...

AI Technical Summary

Problems solved by technology

Although the existing ordinary microscopic instruments can be clamped, they are not reliable and are prone to slippage during the butt joint anastomosis of blood vessels and nerves

At present, special personnel are often required to support the suture of blood vessels and nerves to ensure the anastomosis of the broken ends. The operation is very laborious, and problems such as loosening, dislocation, and penetration of sutures caused by human factors are very easy to occur during suturing, and the effect is often unsatisfactory.
