| titleOfInvention | Preparation method of porous titanium-alloy femoral head support rod in bionic bone trabecula structure |
| abstract | The invention relates to a preparation method of a porous titanium-alloy femoral head support rod in a bionic bone trabecula structure. The support rod is prepared from titanium alloy powder by printing by adopting an SLM (selective laser melting) or EBM (electron beam melting) technology, wherein the titanium alloy powder serves as a raw material, has low modulus of elasticity and has a particle size of less than 45mu m. The structure of the support rod structure is similar to that of the human cancellous femoral neck bone trabecula so that the modulus of elasticity of the support rod is made to be similar to that of the human femoral neck as much as possible and the phenomenon that the support rod becomes loose can be reduced effectively. In addition, the surface of the support rod is provided with a poly(lactic-co-glycolic acid (PLGA) nanoparticle, bone morphogenetic protein-2 (BMP-2) and a vascular endothelial growth factor (VEGF) complex so that a growth factor slow-release effect can be achieved and the bone tissue can grow into the support rod. |
