Self-locking joint for external bone fixator and regulating type bionic external bone fixator

Abstract

The invention relates to a self-locking joint for an external bone fixator and a regulating type bionic external bone fixator. The self-locking joint for the external bone fixator comprises a self-locking joint head A, a self-locking joint head B, a self-locking joint pin shaft and a spherical pad, wherein the self-locking joint head A comprises a spherical self-locking joint hinge seat and a threaded self-locking joint connector A arranged on the spherical self-locking joint hinge seat, the self-locking joint head B comprises a self-locking joint hinge plate and a threaded self-locking joint connector B arranged on the self-locking joint hinge plate, the self-locking joint hinge plate is connected with the spherical self-locking joint hinge seat through the self-locking joint pin shaft in a hinge mode, the diameter of the self-locking joint hinge plate is smaller than the diameter of the spherical self-locking joint hinge seat, and the spherical pad is sleeved on the threaded self-locking joint connector B and is contacted with the arc-shaped surface of the spherical self-locking joint hinge seat. The regulating type bionic external bone fixator with the self-locking 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 a bone external fixator and an external bone fixator. Background technique [0002] In the process of modernization of medical technology, great progress has been made in the material and structure of bone external fixators. The outstanding ones are undoubtedly the hole-ring type external fixator invented by Russian medical expert Ilizarov, the hole-ring type external fixator and the thin steel external fixator. The needle-stretching technology makes the original bone external fixator change its texture in the mechanical action mode and mechanobiological properties, improves its regulation performance, and has a wider range of indications, which is a major progress in the field of bone external fixator technology. Ilizarov's technology has also stimulated the interest of countless orthopaedic surgeons in the study, research and application of bone external fixation technology. Later, Dror Paley of the United...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a self-locking joint for external fixator and a control-type 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 mechanobiological environment), and solve the problems of high manufacturing cost and expensive use of traditional bone external fixators
