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.

Embodiment Construction

[0015] The present invention comprises left pliers arm 1, right pliers arm 2, central rotating shaft 3, left pliers arm 1 and right pliers arm 2 are rotationally connected by central rotating shaft 3, the rear portion of left pliers arm 1 and right pliers arm 2 has ring handle 4, These structures are the same as general-purpose surgical forceps. In order to cooperate with the improvement of the present invention, the above-mentioned left tong arm 1 and right tong arm 2 adopt a hollow tube structure.

[0016] As shown in the figure, the present invention adds an openable tong head 5 to the front ends of the left tong arm 1 and the right tong arm 2 respectively, and the plane of the tong head 5 is perpendicular to the plane formed by the left tong arm 1 and the right tong arm 2. The clamp head 5 is used for clamping blood vessels or nerves, which simplifies the operation steps in the operation and realizes the single-person operation of clamping, anastomosis and fixing.

Abstract

The present invention discloses microsurgery forceps with double forceps heads capable of clamping and fixing, and belongs to the technical field of medical equipment. The microsurgery forceps are used for performing clamping and fixing operation. The technical scheme is that the double forceps heads capable of clamping and fixing are added to traditional operating forceps, blood vessel or nerve can be clamped by clamping pieces at front ends of the forceps heads, the clamping pieces are connected with pull rods, a stay cable and pull rings, and a clamping spring is disposed between the two clamping pieces. After the blood vessel or the nerve is clamped by the forceps heads, the forceps heads at two sides are shut towards the middle by closing handles at two sides of the operating forceps, so that anastomosis butt joint of two broken ends can be achieved. The microsurgery forceps are reasonable in structure, simple and flexible in operation and firm in fixation, the blood vessel can be prevented from being repeatedly clamped during an operation, man-made damage can be prevented, and one-man operation of clamp, measurement, anastomosis and fixation is achieved. The microsurgery technology is innovated, the disadvantages in a microsurgery operation that broken ends of blood vessel and nerve are poorly anastomosed, and specially-assigned person auxiliary operation is usually required are effectively prevented, operation time is shortened, and patient pain is effectively relieved.

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...
