Bone plate fixing plate which is in accordance with bone healing process

Abstract

The invention provides a bone plate fixing system which is in accordance with the bone healing process. The bone plate fixing system comprises a main bone plate and a sliding bone plate, the main bone plate and the sliding bone plate are fixed to two segments of broken bones respectively, the portion, located at the junction of the two segments of broken bones, on the sliding bone plate is provided with a step-shaped groove, the main bone plate is provided with a dovetail guide rail and extends into a dovetail groove of the sliding bone plate, the dovetail guide rail slides in the axial direction through a fine tuning nut and a sliding screw on the dovetail groove to promote healing of the two broken bones, the sliding screw penetrates through the dovetail groove to be arranged on the dovetail guide rail and is sleeved with the fine tuning nut, the fine tuning nut is located above an elastic round cylinder of the sliding screw, and the elastic round cylinder is driven to generate deformation through creep generated by the fine tuning nut. According to the bone plate fixing system which is in accordance with the bone healing process, harmful stress is reduced, the extruding distance of the elastic round cylinder is adjusted through the fine tuning nut, and the bone plate fixing system meets the requirement for the bone plate by human bodies with different weights, and achieves elastic firm fixation in the early stage of healing and elastic fixation in the later stage of healing of the broken bones.

Description

technical field [0001] The invention relates to the field of bone plate technology, in particular to a bone plate fixation system conforming to the bone healing process. Background technique [0002] In modern society, with the increasing number of vehicles and the frequent occurrence of traffic accidents, as well as the increase of the aging population in the world, human fractures often occur due to direct external force or accidental injury. At present, there are two methods of treatment for fractures: external fixation of traditional conservative treatment and internal fixation of surgical treatment. The method of internal fixation of fractures is to reduce and fix the fracture through surgical implantation of instruments. The fixation instruments generally use bone plate system. The Society of Fixation proposed the AO mechanically strong internal fixation method, and the bone plate designed under the guidance of this method emphasizes the absolute strong internal fixati...

Problems solved by technology

Subsequently, domestic scholars proposed a third healing method, that is, based on the first-stage method, a large amount of hematoma tissue was generated, and a small amount of displacement between the broken bones was generated in the later stage to stimulate the generation of external callus, thereby restoring the mechanical properties of the bone and promoting fracture healing. At present, most of the research on the third healing method is in the stage of theoretical discussion, and has not been popularized in practical application.
