Customized far-end dissect type bone plate design method based on patient femur parameter

The invention discloses a customized far-end dissect type bone plate design method based on patient femur parameters; the method comprises the following steps: leading in a patient fracture model, and measuring effective femur model parameters; using the effective femur parameters to build up a patient femur curved surface characteristic model, projecting a main fracture line to the femur model, restoring main fracture traces, and building up a femur fracture reset curved surface model; drafting a customized contour sketch on a femur sagittal surface, projecting the contour to the femur reset model, obtaining a local curved surface to form a femur binding surface, parameterizing the binding surface contour, and building up mapping between the femur parameters and the binding surface parameters; extending the binding surface outwards at unequal pitchs in a sagittal surface direction so as to build up a bone plate entity, defining entity characteristics, building up mapping between the binding surface and entity characteristic parameters, and forming bone plate characteristics; leading out the characteristics so as to generate a customized bone plate. The customized far-end dissect type bone plate design method uses patient femur parameters to directly and accurately build up the customized dissect type bone plate, can fast generate a same kind bone plate according to parametric modification, thus providing important meanings for customized design of the patient bone plate in a bone surgery.
