Split type elastic pressure regulating steel plate

Abstract

The invention discloses a split type elastic pressure regulating steel plate, comprising a steel plate body, a pressure regulating device 1 and a pressure regulating device 2, the pressure regulatingdevice 1 is provided on one side of the steel plate body, the pressure regulating device 2 is provided on the other side of the steel plate body, the pressure regulating device 1 is connected with thepressure regulating device 2 through a traction rod, and at least one of the pressure regulating device 1 or the pressure regulating device 2 is an elastic pressure regulating device. The steel platebody is provided with a pressure regulating screw hole, a bone screw is installed in the pressure regulating screw hole, and the pressure regulating device 1 and the pressure regulating device 2 areused for regulating the radial stress of the bone screw in the pressure regulating screw hole. The invention is easy to fix and convenient to operate. Fix the steel plate body on the bone through thebone screws in the fixing screw holes, regulate radial stress of the bone screws in the pressure regulating screw holes slightly through the elastic pressure regulating devices in the pressure regulating holes, to regulate axial stress of the fracture end, avoid stress shielding of the fracture end, accelerate fracture healing, reduce the incidence rate of nonunion, delayed union and refracture after removing the plate, and shorten the fracture healing time.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a split-type elastic 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 fract...
