[Optimization Design of Interbody Fusion Cage withDifferent Bone Densities Printed in 3D].
Based on the original data of cervical spine, the models of cervical C6 and C7 segments were reconstructed through medical image processing and reverse modeling operations, then the models were assembled to obtain the basic data of interbody fusion cage. According to the basic data, the structures of rectangular porous, gradient porous and octahedral porous interbody fusion cages were established respectively. Maximum force on the adult male neck was applied to the fusion device, and the stress, strain and maximum deformation of the fusion device were solved by finite element analysis. The elastic modulus decrease of the design, and the rectangular porosity structures with different porosity were analyzed and optimized. The results showed that the elastic modulus of the fusion cage with three structures decreased in varying degrees, and the porosity of the interbody fusion cage with rectangular structure was about 60%, which was the most decreased elastic modulus.
