Adjustable multipurpose fracture reduction outer fixing frame

Abstract

The invention discloses an adjustable multipurpose fracture reduction outer fixing frame which comprises at least one set of fixing frame body. The fixing frame body comprises an axial adjusting screw, two axial adjusting devices arranged at the two ends of the axial adjusting screw, two main brackets, two horizontal adjusting devices, two vertical adjusting devices as well as a main needle clamp and an auxiliary needle clamp which are fixed with the horizontal adjusting device and vertical adjusting device on the same side; a fracture fixing needle is arranged on the main needle clamp and the auxiliary needle clamp respectively; the horizontal adjusting device drives the main needle clamp and the auxiliary needle clamp to move in a horizontal direction; the vertical adjusting device drives the main needle clamp and the auxiliary needle clamp to move in a vertical direction; and the axial adjusting device drives the main needle clamp and the auxiliary needle clamp to move in an axial direction. The adjustable multipurpose fracture reduction outer fixing frame disclosed by the invention realizes convenient and accurate alignment and adjustment, has better generality and universality in treating fracture, and is firm and reliable and small in volume; and moreover, the needle through hole is flexibly adjusted, and the functional exercise of the joint can be taken at the early stage after operation.

Description

technical field [0001] The invention relates to a surgical medical machine, in particular to an adjustable multi-directional fracture reduction external fixator for accurate reduction and fixation of fractures and early functional exercise. Background technique [0002] At present, the fracture external fixation bracket has the function of adjusting elongation and shortening, and can only correct the separation or overlap of the fracture axis. After being fixed with the fracture external fixation bracket, when the fracture axis is angled, left and right separation, or front and rear separation, it is difficult to adjust and reset. The existing external fixation brackets for fractures only have the function of fixation and have no function of reduction. It often occurs that the alignment of fractures is still poor after being fixed with external fixation brackets for fractures, which is difficult to meet the needs of accurate alignment and convenient adjustment of fractures in...

AI Technical Summary

Problems solved by technology

Existing external fixation brackets for fractures are bulky and not suitable for small joint fractures of hands and feet

When the fracture near the joint is fixed, it is difficult to exercise the early function of the joint, so it is not suitable for the fracture of the joint

Due to the inconvenient disassembly and combination of most fracture external fixation brackets, they are only aimed at a single fracture in a certain part, and the versatility and extensiveness of treating fractures are poor.
