Abstract: An expandable orthopedic implant includes a casing pipe, a shaft, a first expandable element and a first link lever. The casing pipe has a first opening, a second opening and an axis passing through the first and second opening. The casing pipe sheathes one end of the shaft, and the other end of the shaft has a top portion disposed out of the first opening. The first expandable element has a first terminal pivoted on the casing pipe and a second terminal. The first link lever has a proximal end pivoted to the top portion and a distal end pivoted to the second terminal. When the top portion is driven moving away from the first opening along an extending direction of the axis, the first link-lever can be pushed by the shaft to enact the second terminal moving away from the axis along a direction perpendicular to the axis.

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.
