Title: VERTEBRAL PLATE INTERBODY FUSION CAGE
Abstract:
A vertebral plate interbody fusion cage comprises a rectangular frame body (1). A screw hole (2) is formed in each of four corners of the rectangular frame body (1), and forms an angle ranging from 5° to 10° with a perpendicular surface. The vertebral plate interbody fusion cage is used in bone graft fusion of a posterior column of a spinal column of a human body. An outer wall of a vertebral plate of the spinal column of the human body has an inclination angle, the middle part is higher, and the two sides are lower; accordingly, by making each of the screw holes (2) form an angle ranging from 5° to 10° with the perpendicular surface, the direction of the adjusted each of the screw holes (2) can be perpendicular to a contact surface of the vertebral plate of the spinal column, which helps screws to be perpendicularly screwed into the vertebral plate and fixed and prevents slides. In this way, a grafted bone tissue of the fusion cage can be more tightly attached to a vertebral plate bone tissue, thereby facilitating the fusion. By arranging the screw holes (2) in an angle and by using the inclination angle of the surface of the vertebral plate of the spinal column, a better effect of the contact between the fusion cage and the interface of the vertebral plate bone can be achieved, and the fusion efficiency of a clinical surgery is improved, and accordingly, the vertebral plate interbody fusion cage is a bone fusion enhancement device that is disposed on the surface of the vertebral plate and that is absolutely different from the conventional interbody fusion cage.
