Integrated pressure adjusting steel plate

Abstract

The invention discloses an integrated pressure adjusting steel plate. The steel plate comprises a steel plate body; the steel plate body is provided with pressure adjusting screw holes and at least one pressure adjusting hole; a bone screw is installed in each pressure adjusting screw hole; a pressure adjusting device is installed in the at least one pressure adjusting hole; and the pressure adjusting device is used for adjusting the radial stress of the bone screw in each pressure adjusting screw hole. The steel plate is easy to fix and convenient to operate; the steel plate body of the steelplate is fixed onto a bone through bone screws in fixing screw holes; the radial stress of the bone screw in each pressure adjusting screw hole is adjusted through the pressure adjusting devices in the at least one pressure adjusting hole, so that the axial stress of the fracture end is adjusted and controlled, stress shielding of the fracture end is avoided, fracture union is accelerated, the incidence rate of fracture nonunion, delayed union and re-fracture after removal of the steel plate is lowered, and the fracture union time is shortened.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to an integrated pressure regulating steel plate. Background technique [0002] Bone fixation plates and fixation nails have been used clinically for many years as internal fixation methods. In the course of clinical treatment, there are many methods for fracture fixation, among which plate fixation is one of the most commonly used methods. Traditional bone fixation The steel plate is to fix the steel plate on the bone with 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 hea...
