Split type pressure regulating steel plate

Abstract

The invention discloses a split type pressure regulating steel plate. The split type pressure regulating steel plate comprises a steel plate body, a first pressure regulating device and a second pressure regulating device; the first pressure regulating device is arranged on one side of the steel plate body; the second pressure regulating device is arranged on the other side of the steel plate body; the first pressure regulating device is connected with the second pressure regulating device through a traction rod; pressure regulating screw holes are formed in the steel plate body; bone screws are installed in the pressure adjusting screw holes; and the first pressure adjusting device and the second pressure adjusting device are used for adjusting the radial stress of the bone screws in thepressure adjusting screw holes. The device is easy to fix and convenient to operate. The steel plate body is fixed to a bone by fixing the bone screws in the screw holes, and the radial stress of thebone screws in the pressure adjusting screw holes is adjusted through the pressure adjusting devices in the pressure adjusting holes, so that the axial stress of the fracture end is adjusted and controlled, stress shielding of the fracture end is avoided, fracture healing is accelerated, fracture non-healing and delayed healing are reduced, the occurrence rate of fracture after the steel plate isremoved is reduced, and the fracture healing time is shortened.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a split-type pressure-regulating steel plate. Background technique [0002] The internal fixation method of bone fixation plate and corresponding pressure-adjusting screw has been used clinically for many years. In the process of clinical treatment, there are many methods for fracture fixation, among which plate fixation is one of the most commonly used methods. Traditional The traditional steel plate is to fix the steel plate on the bone through the corresponding pressure-adjusting screw, so that the steel plate and the bone are integrated, but the stress shielding effect in the later stage of fracture repair limits the mechanical stimulation of the bone tissue, and cannot give suitable stress stimulation to the fracture end, especially when it is comminuted. There are disadvantages such as delayed bone union, nonunion, slow bone mineralization rate, and long time wi...

Traditional The traditional steel plate is to fix the steel plate on the bone through the corresponding pressure-adjusting screw, so that the steel plate and the bone are integrated, but the stress shielding effect in the later stage of fracture repair limits the mechanical stimulation of the bone tissue, and cannot give suitable stress stimulation to the fracture end, especially when it is comminuted. There are disadvantages such as delayed bone union, nonunion, slow bone mineralization speed, and long frame time, which limit its popularization and application.
