    Abstract: An artificial joint includes a first joint assembly and a second joint assembly. The first joint assembly is adapted to be connected to a first bone and has a first contacting surface, wherein the first contacting surface includes a first convex arc surface, a second convex arc surface, and a third convex arc surface. The second joint assembly is adapted to be connected to a second bone and has a second contacting surface, wherein the second contacting surface is in contact with the first contacting surface and includes a first concave arc surface, a second concave arc surface, and a third concave arc surface, and the first concave arc surface, the second concave arc surface, and the third concave arc surface respectively correspond to the first convex arc surface, the second convex arc surface, and the third convex arc 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.

    Abstract: The disclosure relates to a spinal intervertebral body fusion device including an adjustable spacer, a first and second pushing piece, and an operative piece. The adjustable spacer includes a first and second supporting plate. The first supporting plate portion is movably installed on the second supporting plate portion. The first and second supporting plate portions form a first and second opening respectively located at two opposite sides of the adjustable spacer. The first pushing piece located at the first opening and is partially clamped by the first and second supporting plate portions. The second pushing piece located at the second opening is partially clamped by the first and second supporting plate portions. The operative piece is movably disposed through the second pushing piece and screwed to the first pushing piece. The operative piece has an annular slot, and the second pushing piece is partially located in the annular slot.
