Mechanical dual-upper-limb dynamic comprehensive restoration of multi-segment bone deformity external fixation bracket

Abstract

The invention relates to a mechanical double-upper-limb dynamic comprehensive restitution multi-section bone malformation external fixing support which comprises a mechanical double-upper-limb dynamiccomprehensive reset component, an adjustable inclined nail clamp restitution composition component and an adjustable external fixing component. The adjustable external fixing component is arranged onone side of a fracture bone, a twisting and locking nail clamp right-angle plate composition restitution component, the mechanical double-upper-limb dynamic comprehensive reset component and the adjustable inclined nail clamp restitution composition component are arranged on the adjustable external fixing component, and a mechanical double-upper-limb dynamic restitution composition component is arranged on the upper portion of the mechanical double-upper-limb dynamic comprehensive reset component. According to the fixing support, a threaded rod of the front end of a bone nail is fixedly screwed into the bone fracture end, and the support imitates double-upper-limbs of a human body to fix the bone fracture end. When a porous nut is pulled by a pull rod, operation is facilitated, whole bonefracture anatomical reset external fixing actions can be completed, firm and stable biomechanics external fixing is achieved, bone fracture curing rate is increased, comprehensive restitution multi-section long malformation bone fracture end accurately resets, and the bone fracture is completely cured.

Description

technical field [0001] The present invention relates to an external fixation bracket, in particular to a mechanical dual-upper-limb dynamic comprehensive restoration of multi-segment bone deformity external fixation bracket, which is used for the comprehensive restoration and external fixation of multi-segment deformities of long bones of human limbs, and is also suitable for open multi-segment long bones The utility model relates to displacement reduction and external fixation of complex fractures with severe deformities, belonging to the field of bone therapy instruments. Background technique [0002] At present, in the technical field of bone therapy equipment, there is no mechanical dual-upper-limb dynamic comprehensive restoration of multi-segment bone deformity external fixation bracket. Existing treatments to correct multi-segment deformities of long bones and open multi-segment severe complex fractures of long bones have unsatisfactory therapeutic effects and fractur...

AI Technical Summary

Problems solved by technology

Existing treatments to correct multi-segment deformities of long bones and open multi-segment severe complex fractures of long bones have unsatisfactory therapeutic effects and fracture reduction, and fracture nonunions often occur. Anatomical reduction; orthopedic experts began to develop computer-aided space external fixator for fracture reduction and external fixation, which has been used clinically for decades to treat bone deformity correction and fracture reduction and external fixation, but it is generally believed that this kind of ring bracket is bulky and It is inconvenient to carry after the operation, which brings inconvenience to life and brings mental fear to the patient. In the operation of using external fixation, install the bracket and correct the fracture, and use the computer to reset the external fixation fracture

The operation is cumbersome and complicated, and the cost is expensive. It is not applicable and cannot be widely promoted. It has not been promoted so far.
