| titleOfInvention | A kind of 3D printing composite material for intervertebral cage and preparation method |
| abstract | The invention discloses a 3D printing composite material for an intervertebral cage and a preparation method, comprising the following raw materials in parts by weight: 40-60 parts of 45S bioglass, 40-60 parts of SrO, 1-3 parts of dopamine hydrochloride, 20-60 parts of Tris-HCl buffer solution, 3-6 parts of L-polylactic acid (PLLA), 1-3 parts of absolute ethanol, 3-5 parts of distilled water; including Sr/Bioglass compounding and modification, mixed powder preparation and Sr/Bioglass compounding and modification Preparation of Bioglass/PLLA scaffolds/fusions. A 3D printing composite material for an intervertebral cage and a preparation method according to the present invention realize the "shape control" and "controllability" operations of the cage based on finite element mechanical simulation and TPMS construction method, and the stiffness and The strength is matched with the human body, controllable degradation, has the advantages of regulating inflammatory response, promoting osteogenesis, inhibiting osteoclasts, etc. It can promote osteogenesis, accelerate intervertebral bony fusion, and reduce the biological mechanism of endplate bone loss, and solve the problem of OLIF vertebral The problems of endplate collapse, cage subsidence and displacement and intervertebral nonunion after interbody fusion. |
