FORMING METHOD FOR ORTHOPEDIC INTERNAL FIXATION

摘要

The present invention relates to the field of orthopedics instrument, and aims to provide a method for forming an orthopedic internal fixation object. In the method for forming the orthopedic internal fixation material, the geometric relationship between the fixation object and the host bone is determined through reverse engineering so that a high degree of fitting is achieved between the fixation object and the host bone, and the stress shielding is reduced, the fixation object is designed into a mortise-tenon structure including a mortise portion, a tenon portion and a dovetail slot plug, to avoid damage to the host bone and reduce stress concentration. The beneficial effects of the present invention lie in that the present invention creatively proposes an individualized forming method for an orthopedic passive internal fixation object. Compared with the prior art, the orthopedic internal fixation object according to the present invention are fixed to the host bone by a mortise and tenon structure to be free from relying on the screw, thus avoiding damage to the host bone, and avoiding the concentration of stress in the fixation process.
