A biomimetic intervertebral disc that prevents bulging and reproduces the instantaneous trajectory of joint movement includes a superior endplate, a core, and a inferior endplate. The upper end of the core is fixed to the lower surface of the superior endplate, and the lower end of the core is fixed to the upper surface of the inferior endplate. The core includes a protective layer, supporting columns, and a nucleus pulposus. The supporting columns have a concave curved surface structure and a negative Poisson's ratio, thereby preventing disc bulging. The supporting columns are divided into four regions: anterior, posterior, left, and right. By adjusting the cross-section and gap size of the supporting columns in each region, the stiffness of different regions of the intervertebral disc can be adjusted. During the compression and deformation process, the nucleus pulposus changes the support point of the superior endplate, causing the rotation center of the vertebral joint to automatically change according to different rotational movements, thus reproducing the motion trajectory of the instantaneous rotation center of the vertebral joint. This invention has the functions of preventing bulging, varying stiffness, and reproducing the motion trajectory of the instantaneous rotation center of the vertebral joint.
