Cervical strain as a result of long-term， bone hyperplasia， or disc prolapse， ligament thickening， resulting in cervical spinal cord， nerve root or vertebral artery compression， a series of clinical dysfunction syndrome， which is a degenerative pathological changes in the basis of At present， the treatment methods of cervical spondylosis， but the results have some Inadequate response to the above-mentioned methods， the design of a cervical interbody fusion cage， the cage after the implantation of human cervical spine to stabilize the spine to form a bony fusion of the degenerative disc to prevent deformation， to some extent， the restoration of intervertebral space In this paper， the software mimics the redevelopment of the cervical spine， and Solidworks software to model， re-use software interface into Solidworks and ANSYS finite element analysis carried The results showed that after cervical spine fusion cage reconstruction after the deformation occurred in the maximum gross load imposed on the side of the zigzag， and the smallest total deformation occurred in the restrictive conditions imposed by the serrated side， the greatest strain and equivalent elastic maximum equivalent stress occurred in the center-right side of the surface location of the post， and the youngest of equivalent elastic strain and stress， such as occurred in the smallest surface of the next cutting-edge Design of cervical interbody fusion cage to meet the intensity of the basic features of cervical spine
