Description

A kind of distal radius fracture reduction forceps

Technical field

The utility model relates to the technical field of medical instruments, in particular to a reduction forceps for distal radius fractures.

Background technique

In hospital orthopedic clinical operations, distal radius fractures are the most common upper limb fractures. For complex distal radius fractures, open reduction and internal fixation is the preferred treatment. During surgery, the distal radius fracture site is usually relatively comminuted. It is time-consuming and labor-intensive to reduce comminuted fractures with ordinary reducers, and it is often a difficult problem to maintain the reduction of distal radius fractures. So far, there is no dedicated reducer for distal radius fractures. It is an urgent task in this technical field to develop a distal radius fracture reduction forceps with simple structure, convenient and practical, stable clamping, and reduction of distal radius fractures.

Contents of the invention

The purpose of the utility model is to provide a distal radius fracture reduction forceps which is simple in structure, convenient and practical, stable in clamping, and capable of resetting distal radius fractures.

For the above purpose, the utility model adopts the following structural technical solutions: a distal radius fracture reduction forceps is composed of a first clamping arm, a second clamping arm, a lock, a limit hook, a hinge and a clamping frame. The characteristics are: the first clamping arm is a stainless steel rod body bent into an S shape, the second clamping arm has the same structure as the first clamping arm, and corresponds to a stainless steel rod body bent into a reverse S shape, the first clamping arm and the second clamping arm The middle parts of the arms are superimposed and connected by a hinge. A clamping space is formed between the two arc-shaped concave first and second clamping arms on the upper part of the hinge. The tops of the two clamping arms are respectively fixed with corresponding rectangular clamping frames. The plane of the clamping frame is concave, which adapts to the bone shape of the dorsal side of the palm at the distal end of the radius. There are anti-skid lines on the plane of the clamping frame; the two arc-shaped first and second clamping arms at the lower part of the hinge form an arc The handshake handle, the inside of the handshake handle is provided with matching hook-shaped locks, and the position is limited by the limit hook, which constitutes a distal radius fracture reduction forceps.

The clamping end of the utility model adopts a rectangular clamping frame suitable for the anatomical bone shape of the distal radius fracture. The space is adapted to the anatomical bone shape of the distal radius fracture, which makes it firm and stable when clamping the bone body. When the hook-shaped lock is locked, it cooperates with the clamping frame with anti-slip lines to maintain the clamping force, which is convenient for the reduction of the distal radius fracture.

The utility model has the advantages of simple structure, convenience and practicality, stable clamping, and is convenient for resetting the fracture of the distal end of the radius, thereby achieving the purpose of the invention.

detailed description

The utility model is further described below in conjunction with the accompanying drawings. Fig. 1 shows the structure of the utility model, a kind of distal radius fracture reduction forceps, which consists of the first clamping arm 6, the second clamping arm 5, the locking buckle 3, the position limiting Composed of hook 4, hinge 2 and clamping frame 1, the first clamping arm 6 is a stainless steel rod body bent into an S shape, and the second clamping arm 5 has the same structure as the first clamping arm, corresponding to a stainless steel rod body bent into a reverse S shape , the first clamping arm 6 overlaps with the middle of the second clamping arm 5, and is hingedly connected by the hinge 2, and the upper part of the hinge 2 is formed between the first clamping arm 6 and the second clamping arm 5 with two arc-shaped concaves. In the clamping space, the tops of the first clamping arm 6 and the second clamping arm 5 are respectively fixed with corresponding rectangular clamping frames 1, and the opposite clamping frame 1 is concave in plane, which adapts to the bone shape of the palmar side of the distal end of the radius , the clamping frame 1 is provided with anti-slip lines 7 on the plane; the two arc-shaped convex first clamping arms 6 and the second clamping arms 5 at the lower part of the hinge 2 form an arc handshake handle, and the inside of the handshake handle is provided with a matching corresponding The hook-shaped lock 3 is limited by the limit hook 4, which constitutes a kind of reduction forceps for distal radius fracture.
