An intervertebral cage having flexibility is provided wherein a housing itself has a plate spring form having proper elasticity. The housing can have a shape memory characteristic to obtain a modulus of elasticity suitable for differing spinal loads according to each patient, thereby absorbing a shock applied to a spine. A distance between disks is restored by the intervertebral cage to sufficiently secure a disc height, thereby relieving spinal nerve stress. The intervertebral cage may be converted from a simple fusion application into a functional cage adequate for a physiological biomechanics. The flexible intervertebral cage includes a housing having a closed sectional surface with an empty hollow therein. The housing itself has proper elasticity so that it absorbs a load by a stress applied in a vertical direction of a spine by a dynamic motion due to an upright walk of a patient to serve as a normal disk.

The present invention provides a cervical spine pillow and its design method, design device, and computer-readable storage medium. By obtaining the X-ray film of the cervical spine head of the customer and the optical scanning file containing the cervical spine head; importing into three-dimensional modeling software, after measurement Obtain the original cervical curvature. When the original cervical curvature is normal, keep the original cervical curvature. When the original cervical curvature is abnormal, adjust the original cervical curvature to normal cervical curvature in one step or in stages. Determine the center of the circle based on the adjusted curvature of the cervical spine, and determine the curvature of the cervical spine in the occipital region of the neck by combining the center of the circle with the X-ray film of the cervical spine head of the customizer and the optical scanning file of the cervical spine head including the cervical spine head; after modeling, the cervical spine pillow is obtained 3D models for 3D printing with flexible materials. The present invention can carry out personalized design according to the cervical spine conditions of different customizers, so that it can completely fit the physiological curvature of the customizer, and realize personalized, precise and customized treatment.
