Problems solved by technology

[0002] Bone plate and bone screw have been used clinically for many years as internal fixation methods. In the clinical treatment process, there are many methods for fracture fixation, among which plate fixation is one of the most commonly used methods. The traditional bone plate The steel plate is fixed on the bone through bone screws, so that the steel plate and the bone are integrated. However, due to the stress shielding effect of the steel plate in the later stage of fracture repair, it is unable to give appropriate stress stimulation to the fracture end, and delayed union, nonunion, and bone mineralization are prone to occur. The speed of transformation is slow, which limits its application

Abstract

The invention discloses a top end pressure adjusting steel plate. The steel plate comprises a steel plate body, a pressure adjusting device I and a pressure adjusting device II; the top end of the steel plate body is provided with the pressure adjusting device I, and the other end of the steel plate body is provided with the pressure adjusting device II; the pressure adjusting device I is connected with the pressure adjusting device II through traction rods; the steel plate body is provided with pressure adjusting screw holes; a bone screw is installed in each pressure adjusting screw hole; and the pressure adjusting device I and the pressure adjusting device II are used for adjusting the radial stress of the bone screw in each pressure adjusting screw hole. The steel plate is easy to fixand convenient to operate; the steel plate body of the steel plate is fixed onto a bone through bone screws in fixing screw holes; the distance between the bone screws in the pressure adjusting screwholes and the bone screws in the fixing screw holes is slightly adjusted through an elastic pressure adjusting device in each of pressure adjusting holes, the stress of the fracture end is adjusted and controlled, body tissue is stimulated to form a new bone, so that the purpose of promoting fracture union is achieved, stress shielding of the fracture end is avoided, fracture union is accelerated,and the fixing time of the steel plate is shortened.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a top pressure regulating steel plate. Background technique [0002] Bone plate and bone screw have been used clinically for many years as internal fixation methods. In the clinical treatment process, there are many methods for fracture fixation, among which plate fixation is one of the most commonly used methods. The traditional bone plate The steel plate is fixed on the bone through bone screws, so that the steel plate and the bone are integrated. However, due to the stress shielding effect of the steel plate in the later stage of fracture repair, it is unable to give appropriate stress stimulation to the fracture end, and delayed union, nonunion, and bone mineralization are prone to occur. The slow speed limits its application. Therefore, designing a steel plate that can adjust the stress of the fracture end and promote fracture healing is a clinical problem that ...
