Combined bone fracture plate with changeable stress

Abstract

The invention discloses a combined bone fracture plate with changeable stress. The bone fracture plate includes a baseplate A, a baseplate B and a limiting screw, wherein the baseplate A, the baseplate B and the limiting screw are only used for fixing a fracture end. The baseplate A and the baseplate B are provided with screw holes respectively, wherein the screw holes are matched with fixing screws; a boss is arranged on one side face of the baseplate A, an insertion groove matched with the boss is formed in one side face of the baseplate B, threaded through holes are formed in the surface ofthe boss, a long through hole extending to the insertion groove is formed in the upper surface of the baseplate B, and the limiting screw penetrate through the long through hole to be detachably arranged in the threaded through holes. The bone fracture plate is reasonable in structure and convenient to use, the stress effect of the bone fracture plate can be effectively alleviated, and normal healing of sclerotin is facilitated.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a combined variable stress bone plate. Background technique [0002] About 700 million people in my country need bone plate internal fixation surgery for long tubular bone fractures every year. Strong internal fixation for bone plate fractures can allow patients to get out of bed early and speed up the recovery process. However, due to bone plate fixation After the fracture, the mechanical stress of the backbone is enhanced, and the steel plate bears the transmission of physiological stress, so that the stress at the fracture end cannot be directly and effectively transmitted, resulting in a "stress shielding" effect, resulting in complications such as delayed union and nonunion of the fracture that lead to treatment failure. fail. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a combined variable stress bone ...
