The invention belongs to the field of medical instruments and lumbar spine fusion, in particular to a vertebral body fusion cage with degradability and high strength, which fits the anatomical structure of human vertebral body. The vertebral body fusion cage of the invention is designed according to the size of the human body vertebral body, and the vertebral body fusion cage adopts a structure inwhich the edge is a concave arc surface and the middle is a convex surface, so that stress concentration is avoided, and the physiological structure of the vertebral body endplate is fitted; at thatsame time, the whole vertebral body fusion cage of the invention is wedge-shaped design, which can maintain the natural curvature of the vertebral body. The vertebral body fusion cage of the inventionadopts metal powder injection model technology, the material is zinc-iron alloy or zinc-iron-calcium alloy, which can not only provide sufficient mechanical support and promote bone fusion in the initial stage, but also slowly degrade in the later stage of bone fusion. Iron ions and zinc ions are metal ions with the first and second abundance in human body respectively, and inflammatory reactionand rejection reaction will not be caused in the degradation process.
