New double-layer structure cervical spinal disc prosthetic and its optimized design / 中国康复理论与实践

@#Objective To solve some problem in present cervical spinal disc.MethodsAfter analyzing the function of cervical spinal disc, 2 kinds of materials were chosen to design and fabricate the double-layer cervical spinal disc prosthetic. CAD and ANSYS technologies were used to optimize 4 kinds of the new prosthetic structure.Results and ConclusionThe materials if the prosthetic is proper, and the double-layer column structure of the new prosthetic shows some excellence characteristics,including maximum stress of nucleus and annulus properly, simple structure and can be facilitated and exactly graft.
