Damping joint and adjustable bionic external fixator for bone external fixator

Abstract

A damping joint for an external bone fixator and an adjustable bionic external fixator, the damping joint for an external bone fixator includes a damping joint head A, a damping joint head B, a damping joint pin, a gasket groove, and a butterfly gasket , U-shaped fixing clip and gasket cover, the damping joint head A includes a damping joint spherical hinge seat and a damping joint threaded joint A arranged on the damping joint spherical hinge seat, and the damping joint head B includes a damping joint hinge piece and The damping joint threaded joint B provided on the damping joint hinge piece, the damping joint hinge piece is hingedly connected to the damping joint spherical hinge seat through the damping joint pin, and the diameter of the damping joint hinge piece is smaller than the diameter of the damping joint spherical hinge seat. The adjustable bionic external fixator adopting the damping joint for the external fixator has the advantages of simple structure, light weight, low cost, adjustable and flexible operation, and can be combined and adjusted in a targeted and personalized manner.

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
