NOVELTY - Personalized dynamic monitoring osteogenic activity spinal fusion system comprises mold prepared by combining electronic computed tomography, three-dimensional modeling, finite element analysis and selective laser melting rapid prototyping technology, using graphene and polyetheretherketone composite material as main material, and injecting added pressure sensor into the mold when the main material is fused. The fusion system is obtained by combining the electronic computer tomography and three-dimensional modeling software to model the pre-implanted fusion cage system, optimizing the model by finite element analysis software, and combining the selective laser melting fast forming technology. USE - Personalized dynamic monitoring osteogenic active spinal fusion system for treating lumbar spinal canal stenosis of a patient during surgical treatment of spinal degenerative disease in the fields of medical materials. ADVANTAGE - The fusion cage system promotes the proliferation and osteogenic differentiation of bone cell in the implantation process, reduces the operation risk, improves the success rate of the operation, and has a bone induction long-characteristics, accurate matching bone grafting interface, remote sensing dynamic detection mechanics and fusion relationship. DETAILED DESCRIPTION - Personalized dynamic monitoring osteogenic activity spinal fusion system comprises mold prepared by combining electronic computed tomography, three-dimensional modeling, finite element analysis and selective laser melting rapid prototyping technology, using graphene and polyetheretherketone composite material as main material, and injecting added pressure sensor into the mold when the main material is fused. The fusion system is obtained by combining the electronic computer tomography and three-dimensional modeling software to model the pre-implanted fusion cage system, optimizing the model by finite element analysis software, and combining the selective laser melting fast forming technology. The optimized model is processed by slicing software and imported into three-dimensional (3D) printer to directly prepare an injection mold. The polyetheretherketone and graphene is stirred and mixed in the molten state uniformly, injected into a personalized injection mold, and pressure sensing device is combined with the main body to obtain personalized dynamic monitoring of osteogenic activity spinal fusion system for performing surface treatment of the fusion cage system.
