Abstract:
An artificial intervertebral disc is configured to be inserted between adjacent human vertebrae. The artificial intervertebral disc includes a first connection block, a joint block and a second connection block. The joint block has a convex surface and a rear surface. The rear surface of the joint block is stacked on the first connection block. The second connection block is slidably stacked on the convex surface of the joint block, such that the second connection block is movable relative to the first connection block. In addition, the convex surface is a curved surface, and the convex surface is arranged off-axis with respect to the rear surface.
