Abstract

The invention discloses an intervertebral fusion device, which is used for implanting in the vertebral space to support the upper and lower adjacent vertebral blocks, which comprises at least four support blocks which are hinged with each other from head to tail in sequence and have a polygonal contour, and the support blocks pass through connecting shafts arranged between them. Free rotation, the support block rotates to the state with the largest contour area, and its polygonal contour matches the size of the bottom surface of the vertebral block, and the support block rotates to the state with the smallest contour area, and its contour width is suitable for implantation. Locking devices that fix their respective positions to shape their overall contours. The support block changes the overall profile by rotating around the connecting shaft to adapt to different application scenarios. The overall profile of the support block is compressed and its overall width is reduced to ensure the safety and convenience of the implantation process with a smaller width; when the implantation process is completed, adjust The contour of the supporting block is stretched, and the size of its contour just matches the size of the bottom area of ​​the vertebral block at this time, so as to achieve a relatively ideal supporting effect.

Description

technical field [0001] The invention relates to the technical field of medical equipment, and more specifically, relates to an intervertebral fusion device for implanting into a spinal space to support upper and lower adjacent vertebral blocks. Background technique [0002] Intervertebral fusion is one of the important methods to treat spinal diseases, and more and more people receive intervertebral fusion every year. Intervertebral fusion includes autologous bone grafting and allograft bone graft fusion. Due to the limited source of autologous bone, increased trauma, and inability to provide immediate mechanical stability, the clinical application of intervertebral fusion is limited; allogeneic bone grafts have high costs, The number is limited and the problem of viral transmission and immune rejection caused by allograft bone. [0003] In recent years, in order to increase the fusion rate of bone grafts, reduce the dependence on external fixation, and improve and maintain...
