| titleOfInvention | A kind of biomimetic prosthetic hip joint with interior growth function |
| abstract | The invention discloses a kind of biomimetic prosthetic hip joint with interior growth function, the joint is made up of artificial cartilage layer, interfacial adhesion layer and porous support, and artificial cartilage and porous support are spheroid shape surface；Articular surface cornerite is 60 120 °, and when cornerite is 80 120 °, 36 equally distributed convex columns are circumferentially devised in prosthese inner surface；The porous coating of bioactivity is prepared in femoral stem outer surface, and coating material is changed in gradient outward by inner；The loose structure that porous support is designed as having gradient according to finite element optimization result, aperture are 300 800 μm；Porosity is 20 85%；The present invention can preserve bone amount to greatest extent and maintain the biomechanical characterization of femur, with good mechanical property and tribological property, by inducing or promoting Oesteoblast growth to ensure prothesis implant body and the effective interface bond strength of natural bone, stability and service life after Using prosthesis are improved. |
