Novel automatic pressure locking steel plate

Abstract

The invention discloses a novel automatic pressure locking steel plate. The automatic pressure locking steel plate particularly comprises a steel plate, a gasket, a buckle, a screw and a slidable hole; the slidable hole is formed in the steel plate, the slidable hole is used for being inserted by the screw, the gasket and the buckle are arranged between the screw and the slidable hole, the gasketand the buckle are in interference fit with the slidable hole, wherein the size of the slidable hole is 1.5-2 times that of the gasket, and the buckle is made of bioresorbable medical materials. The novel automatic pressure locking steel plate can automatically press a broken end of fracture, reduce stress shielding, facilitate the rapid formation of an osteotylus, and promote fracture healing.

Description

technical field [0001] The invention relates to the field of medical devices, and more particularly relates to a novel automatic pressure locking steel plate. Background technique [0002] With the continuous development and progress of society, the development of transportation and the increase of population mobility, the use of large-scale equipment in industrial and mining enterprises, the number of orthopedic trauma patients is increasing. Due to the continuous improvement of the industrial level and the continuous introduction of various new technologies, the surgery of trauma orthopedics has also advanced by leaps and bounds. The application of various internal fixation materials provides a basis for the development of orthopedic technology. However, what follows is that the occurrence of internal fixation fractures after fractures is also increasing. This not only brings unnecessary pain to patients and forms medical disputes, but also puts higher demands on orthope...

AI Technical Summary

Problems solved by technology

However, in modern internal fixation plates, the fretting between bone fragments close to the plate side is often less than 0.15mm, making the formation of callus on the plate side slower than that on the side away from the plate, and asymmetric callus is easy to form

[0005] The problem of the modern locking system is that the steel plate has high rigidity, there is a problem of stress shielding, the fretting between the fracture fragments is reduced (especially on the side of the bone plate), the callus is less and grows slowly, and the callus is asymmetrical, which causes fracture nonunion and non-union. Complications such as joint and internal fixation fractures are not conducive to primary fracture healing
