The radial styloid process is located at the distal end of the radius. The distal radius fracture is a fracture within 3cm from the distal radius joint surface, the fracture is mainly caused by indirect violence, the most common injury mechanism is hyperextension support of hands during falling, and then sports-related injury and traffic accidents are caused, and osteoporosis is an important factor for frequent distal radius fractures of old people.

When the operation is performed on the distal radius fracture, the fractured bone mass at the distal radius needs to be wrapped and reset, and then the fractured bone mass is fixed by using a kirschner wire. The kirschner wire is a commonly used internal fixation material for orthopedics, is used for fixing short fracture or avulsion fracture and other fracture with low stress, and is also used for temporarily fixing fracture blocks in orthopedic surgery.

Detailed Description

The embodiment of the utility model provides the pair of reduction forceps for distal radius fracture, solves the technical problem of distal radius fracture in the prior art, realizes rapid reduction of fractured bone pieces, and is convenient and fast to use.

In order to solve the above problems, the technical solution in the embodiments of the present invention has the following general idea: the anatomical form of the radius side and the ulna side of the distal radius is used for manufacturing anatomical form distal radius fracture reduction forceps which are more suitable for the surface of the radius side, a radius styloid head is manufactured in the form of a radius styloid located on the radius side face of the distal radius, the radius styloid head is installed on a clamping arm of the forceps, the radius styloid head is used as the first matching point, the radius styloid head is clamped on the radius side face of the distal radius of the radius and then wraps the head to abut against the ulna side face of the distal radius, fractured bone blocks of the distal radius are wrapped, and the forceps are matched with a Kirschner wire to be temporarily fixed and reduced conveniently.

For better understanding of the above technical solutions, the following detailed descriptions will be provided in conjunction with the drawings and the detailed description of the embodiments.

Referring to fig. 1 to 6, a preferred embodiment of the distal radius fracture reduction forceps of the present invention.
