Damping joint for external bone fixator and regulating type bionic external bone fixator

Abstract

The invention relates to a damping joint for an external bone fixator and a regulating type bionic external bone fixator. The damping joint for the external bone fixator comprises a damping joint head A, a damping joint head B, a damping joint pin shaft, a gasket groove, a butterfly gasket, a U-shaped fixing clip and a gasket cover, wherein the damping joint head A comprises a spherical damping joint hinge seat and a threaded damping joint connector A arranged on the spherical damping joint hinge seat, the damping joint head B comprises a damping joint hinge plate and a threaded damping joint connector B arranged on the damping joint hinge plate, the damping joint hinge plate is connected with the spherical damping joint hinge seat through the damping joint pin shaft, and the diameter of the damping joint hinge plate is smaller than the diameter of the spherical damping joint hinge seat. The regulating type bionic external bone fixator with the damping joint has the advantages of simple structure, light weight, low cost, regulating capability and flexible operation, and targeted and personalized combination and regulation can be realized.

Description

technical field [0001] The invention relates to a joint arranged on an external bone fixator and an external bone fixator. Background technique [0002] In the process of modernization of medical technology, the material and structure of bone external fixator have made great progress. The outstanding one is undoubtedly the hole ring type external fixator invented by Russian medical expert Ilizarov, the hole ring type external fixator and fine steel The needle stretching technology has changed the texture of the mechanical action mode and mechanical biological properties of the original external fixator, improved the regulation performance, and expanded the indications. It is a major advancement in the field of external fixator technology. Ilizarov's technology has also stimulated countless orthopedic surgeons' interest in learning, researching and applying external bone fixation technology. Later, Dror Paley in the United States compiled "Principles of Orthopedic Surgery", c...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a damping joint for external fixator and a controllable bionic external fixator that can meet the requirements of strong fixation in the early stage of fracture, elastic fixation with axial and comprehensive stress stimulation in the middle stage, and balanced fixation in the later stage. To solve the compatibility of mechanical energy (mechanical environment) and biological energy (tissue regeneration) (the rationality of the mechanical biological environment), and solve the problems of high manufacturing cost and expensive use of traditional bone external fixators
