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.

Abstract: A bone screw includes an external screw thread, an internal supporter structure and a porous layer. The internal supporter structure is inside the external screw thread. The internal supporter structure includes a screw thread supporter or a polygonal wall supporter. The porous layer is on a surface of the internal supporter structure. Therefore, the bone screw has an increased strength and also provides postoperative healing effect.
