Zusammenfassung:	An artificial intervertebral disc is used to combine with a human intervertebral disc. The artificial intervertebral disc includes a first assembly block, a joint block and a second assembly block. The joint block has a sliding convex surface and a back surface. The back of the joint block is stacked on the first assembly block. The second assembly block is slidably stacked on the sliding convex surface of the joint block to make the second assembly block bend relative to the first assembly block. Among them, the sliding convex surface is an arc surface and is arranged off-axis.
