Description

Bilobal reduction forceps for hand and foot surgery fractures

technical field

The invention relates to the field of medical instruments for hand and foot surgical fractures, in particular to a double-leaf reduction forceps for hand and foot surgical fractures.

Background technique

Fractures of the hands and feet are mostly small long tubular bones. There is no suitable reduction forceps for fracture reduction. Generally, vascular forceps are used to clamp and fix the fracture during surgery, and then fixed with Kirschner wires, plates, screws, etc., and the vascular forceps are all For the straight leaf, when the fracture is clamped and fixed, the angle is relatively large, and the force points on both sides are not on the center line of the fracture, which is easy to cause slippage and unstable fixation, which affects the quality of fracture reduction and internal fixation. In addition, when fixing the fracture end, both hands or two people must maintain the fixation.

Contents of the invention

The technical problem mainly solved by the present invention is to provide a double-leaf reduction forceps for hand and foot surgery fractures, which can make the stress points on both sides of the bone be on the center line of the bone when the hand and foot fracture is reset, and hold the bone firmly without slipping , the fracture end is not easy to shift during the internal fixation operation, the internal fixation quality is high, the clamping places are located on both sides of the fracture end after reduction, and the fixation can be maintained with one hand, which makes the operation easier and easier, shortens the operation time, and improves Quality of fracture fixation.

In order to solve the above technical problems, a technical solution adopted by the present invention is to provide a double-leaf reduction forceps for hand and foot surgery, including: upper forceps, lower forceps and rivets; the upper forceps includes an upper forceps head, an upper forceps body and an upper The pliers handle, the upper pliers head and the upper pliers handle are respectively fixed at both ends of the upper pliers body, and there are upper rivet holes on the upper pliers body near the upper pliers head; the lower pliers include a lower pliers head, a lower pliers body and a lower pliers handle , the lower pliers head and the lower pliers handle are respectively fixed at both ends of the lower pliers body, and the lower pliers body near the lower pliers head has a lower rivet hole; the rivet passes through the upper rivet hole and the lower rivet hole to hinge the upper pliers and the lower pliers; The upper pliers head includes an upper V-shaped connecting rod and a pair of arc-shaped pliers, the middle part of the upper V-shaped connecting rod is connected and fixed with the upper pliers body, and the two arc-shaped pliers are respectively fixed at both ends of the upper V-shaped connecting rod; The lower pliers head includes a lower V-shaped connecting rod and a pair of flat pliers. The middle part of the lower V-shaped connecting rod is connected and fixed with the lower pliers body. The pliers are set corresponding to each other, and the arc-shaped jaws of the arc-shaped pliers are facing the flat pliers.

Preferably, an upper rack is fixed on the upper pliers close to the upper pliers handle, and the upper rack is located on the side of the upper pliers corresponding to the lower pliers; a lower rack is fixed on the lower pliers corresponding to the upper rack , the lower rack meshes with the upper rack.

Preferably, the upper tongs, lower tongs, upper rack and lower rack are all made of stainless steel.

The beneficial effects of the present invention are: the present invention can effectively prevent bone slippage when clamping the fracture end, can be respectively fixed on both sides of the fracture end, is convenient for the operator to perform internal fixation, can significantly shorten operation time, improve operation efficiency, and improve fracture reduction Internal fixation quality.

detailed description

The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

Please refer to Fig. 1 and Fig. 2, the embodiment of the present invention comprises:

A double-leaf reduction forceps for hand and foot surgical fractures, comprising: upper forceps, lower forceps and rivets; the upper forceps includes an upper forceps head, an upper forceps body 3 and an upper forceps handle, and the upper forceps head and the upper forceps handle are respectively fixed on the upper forceps At both ends of the body 3, there are upper rivet holes on the upper tong body 3 close to the upper tong head; At both ends of the pliers body 6, there are lower rivet holes on the lower pliers body 6 near the lower pliers head; the rivets pass through the upper rivet holes and the lower rivet holes to hinge the upper and lower pliers; the upper pliers head includes an upper V Type connecting rod 2 and a pair of arc-shaped pliers 1, the middle part of the upper V-shaped connecting rod 2 is connected and fixed with the upper pliers body 3, and the two arc-shaped pliers 1 are respectively fixed at both ends of the upper V-shaped connecting rod 2; the lower pliers The head includes a lower V-shaped connecting rod and a pair of flat pliers 5, the middle part of the lower V-shaped connecting rod is connected and fixed with the lower pliers body 6, and the two flat pliers 5 are respectively fixed at both ends of the lower V-shaped connecting rod; the arc-shaped pliers 1 Corresponding to the flat tongs 5, the arc-shaped jaws of the arc-shaped tongs 1 face the flat tongs 5, and a pair of arc-shaped tongs and a pair of flat tongs form a double-leaf structure. On the upper pliers body 3, an upper rack 4 is fixed near the upper pliers handle, and the upper rack 4 is located on the side corresponding to the lower pliers body on the upper pliers body; the position corresponding to the upper rack 4 on the lower pliers body 6 is fixed There is a lower rack 7, and the lower rack 4 is engaged with the upper rack 7.

When reducing the fracture of the hand and foot, the force points on both sides of the bone can be on the center line of the bone, and the bone can be held firmly. The centerline of the bone mass prevents the clamped bone from slipping, and the fracture end is not easy to shift during the internal fixation operation. The internal fixation quality is high, and the clamping points are located on both sides of the fracture end after reduction, and the fixation can be maintained with one hand , making the operation more convenient and easy, shortening the operation time, and improving the quality of fracture internal fixation.

The above is only an embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structures made by using the description of the present invention and the contents of the accompanying drawings, or directly or indirectly used in other related technical fields, are all the same. included in the scope of patent protection of the present invention.
