Combined fusion cage

The invention discloses a combined type fusion cage, and belongs to the technical field of orthopedic implants, the combined type fusion cage comprises a fusion cage main body, the fusion cage main body is composed of at least three support bodies extending in the axial direction in the circumferential direction, each support body is made of only one material, and the at least three support bodies at least comprise two materials; the opposite end faces of the adjacent supporting bodies are each provided with a mortise and tenon joint structure, so that self-locking is formed after the supporting bodies are combined, and a whole which cannot be separated in the single direction is formed. The elastic modulus of the combined fusion cage is close to that of cortical bones of a human body, the stability is good, and the bone fusion rate is high. 本发明公开了一种组合式融合器，属于骨科植入物技术领域，所述组合式融合器包括融合器主体，融合器主体在周向上由至少三个沿轴向延伸的支撑体构成，每个支撑体只使用一种材质，至少三个支撑体至少包含两种材质；相邻支撑体相对的端面上均设有榫卯结构，以使各支撑体组合后形成自锁，从而成为一个无法通过单一方向分离的整体。本发明的组合式融合器弹性模量与人体皮质
