An embodiment of the present invention discloses a 3D printed bionic artificial intervertebral joint prosthesis, which includes an artificial intervertebral disc, an artificial vertebral body implant prosthesis, a surface porous structure, and a first mounting plate. The artificial intervertebral disc includes an artificial annulus fibrosus in contact with the end plate of the first vertebral body and a first mounting plate combined with the artificial vertebral body. The artificial vertebral body implant prosthesis includes a mounting seat fixed to the artificial intervertebral disc and an implant vertebral body fixed to the lower vertebral body. The implant vertebral body realizes the replacement of the osteotomized part and the fixation with the second vertebral body. The cooperation between the first mounting plate and the mounting seat completes the fixation of the artificial intervertebral disc. The contact between the artificial intervertebral disc and the first mounting plate realizes the movement of the bionic artificial intervertebral joint prosthesis.

The present invention provides an artificial cervical intervertebral disc barb fixation device. The device includes a first barb structure and at least one second barb structure arranged on the surface of the first barb structure. The second barb structure includes a fixing piece and a spur. The spur includes a vertically arranged needle and a plurality of groups of barb hooks. In the initial state, the top of the spur is protruding from the top of the fixing piece. A driving assembly is provided inside the fixing piece. When the top of the second barb structure is subjected to pressure, the driving assembly can drive the spur to move toward the outside of the fixing piece and make at least one group of barb hooks located outside the fixing piece. Therefore, after the prosthesis is implanted, under the tension of the tissue structure around the patient's cervical spine and the gravity of the cervical spine and head, the first barb structure and the second barb structure are pressed into the upper and lower vertebrae. Under the action of pressure, the spur moves outward and makes at least one group of barb hooks located outside the fixing piece to penetrate into the bone of the adjacent vertebrae to form barbs, thereby increasing the immediate stability with the bone tissue.
