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.

Abstract: A low-profile offset-type spinal fusion device includes a first screw, a connection base, a nut and a compression part. The first screw has an external thread and a flange. The connection base includes a penetration part and a connection part disposed no higher than the penetration part, and can sleeve the first screw through a first hole of the penetration part to contact the flange with opposite ends of the first screw protruding out of the first hole. The nut, used to engage the first screw, has a bottom surface to contact against the penetration part. When the first screw is installed by penetrating the first hole, the nut and the flange are located to opposite ends of the first hole. The compression part is to screw into a cavity of the connection part for depressing a connecting bar tightly in the cavity.
