Description

Reduction regulator for bone holding forceps

Technical Field

The utility model relates to the technical field of orthopedic medical equipment, in particular to a reduction regulator for bone holding forceps.

Background

Fracture refers to complete or partial fracture of bone structure, which is often seen in children, the elderly, and young and middle-aged people. During fracture treatment, the first step is to perform traction reduction on the fractured part, so that the fractured end is restored to be normal or close to the original anatomical relationship to restore the support function of the skeleton. The existing fracture reduction mostly adopts a bone holding forceps to carry out traction, the mode has better effect on shorter bone blocks, and when a longer bone joint is fractured, the bone blocks on two sides of the bone joint cannot be adjusted when the bone holding forceps are used for traction so that the fractured bone joint is reduced to the force line state before the fracture.
