Abstract
The invention discloses an interbody fusion cage, and relates to the technical field of medical instruments. According to one specific embodiment, the interbody fusion cage comprises a supporting structure and a pore structure, wherein the supporting structure comprises an upper supporting surface, a lower supporting surface and a supporting column, the upper end of the supporting column is connected with the side edge of the upper supporting surface, and the lower end of the supporting column is connected with the side edge of the lower supporting surface; the pore structure is arranged in acavity formed by the upper supporting surface, the lower supporting surface and the supporting column; and a through hole for accommodating a spine is formed in the center of the pore structure. According to the embodiment, the size of the fusion cage can be greatly reduced, the porosity of the fusion cage is improved, and a good bone fusion effect is achieved.
Description
technical field [0001] The invention relates to the technical field of medical instruments, in particular to an intervertebral fusion device. Background technique [0002] The intervertebral fusion cage has functions such as support and load sharing, and can better restore the height of the intervertebral space and the physiological curvature of the spine. [0003] There are at least the following problems in the fuser in the prior art: [0004] (1) Most of the existing fusion devices are composed of a solid frame structure and a through-hole structure. The solid support mostly adopts the solid axial support surface, which will greatly occupy the volume of the fusion cage, resulting in too small porosity of the fusion cage and affecting the effect of bone fusion; [0005] (2) The fuser in the prior art is easy to cause the problem of loosening and displacement in the later stage of implantation; [0006] (3) The existing pore structure is mostly composed of regular space ...
