In-situ rotary bone fracture restoration fixer

Abstract

The invention relates to an in situ rotary fracture reduction fixer, comprising two pliers handles hinged to each other and a pair of fixing plates, the pair of fixing plates are used to clamp and fix the fracture site; the rear parts of the two pliers handles are Elastic locks are provided, and the opposite elastic locks are used to lock the distance between a pair of fixed plates. The rear ends of the two pliers handles are provided with ring handles; the front ends of the pliers handles are designed with arc-shaped pliers heads. The end of the pliers head is connected to the fixed plate via a ball-and-socket shaft. When the elastic lock is locked, the two pliers handles can rotate at a certain angle relative to the fixed bone; the inner part of each fixed plate There are no less than two positioning protrusions on the side; the two pliers handles and a pair of fixing plates can be disassembled from the ball-and-socket shaft. The fracture reduction fixer of the present invention can be rotated in situ, leaving room for screw screwing in, and can choose to install fixing plates of different lengths and radians according to the size of the backbone.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a temporary fixer used for long bone shaft fracture surgery. Background technique [0002] Temporary reduction and fixation of fractures is a commonly used device in orthopedic surgery. When internal fixation of long bone shaft fractures is performed with plates, it is necessary to reduce the fracture and use temporary fixation devices to assist in fixing the fracture end, so as to temporarily reduce and stabilize the fracture, so that the plate can be placed and the fixation screws screwed in. . However, most of the current temporary fixers for fractures are two-claw, three-claw or pincer type bone holders. After the long bone shaft fracture is reset, the bone holder needs to be loosened and then the steel plate is placed. For unstable fractures, repeated fracture reduction and fixation are required, which brings inconvenience to the operation, prolongs the operation time, and ...

Problems solved by technology

However, most of the current temporary fixers for fractures are two-claw, three-claw or pincer-type bone holders. When the long bone shaft fracture is reset, the bone holder needs to be loosened and then the steel plate is placed. For unstable fractures, repeated fracture reduction and fixation are required, which brings inconvenience to the operation, prolongs the operation time, and increases the chance of infection
