▎ 摘　　要

(CN210186109-U) NOVELTY - The utility model claims a bone defective artificial prosthesis, comprising a prosthesis stem and bone repair growth factor layer, the prosthesis stem is porous structure, the part of the outer surface of at least dry the prosthesis provided with a repairing bone growth factor layer, repairing bone growth factor layer comprising oxidized graphene and calcium phosphate ceramic, bone defect artificial prosthesis made of 3D printing. The utility model prosthesis combined repairing dry good mechanical performance reconstruction function of bone repair and growth factor layer, so it has good initial stability and excellent osteogenic ability, long-term good repairing effect, adopts 3 D printing capable of precise design according to actual situation, perfect matching, can solve many problems faced by clinically segment bone defect repair. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the artificial bone defect prosthesis.
