技術摘要 / Our Technology:
一種椎間融合裝置,包括結構陶瓷體。該結構陶瓷體具有底面、頂面、銜接底面與頂面之間的周面、以及貫通底面與頂面的至少一個通孔。通孔的內側表面是內凸型曲面或者通孔是漏斗狀表面。在具有內凸型曲面的通孔中,通孔的孔徑由所述通孔的中心往底面與頂面逐步擴大。通孔的孔徑也可由底面往頂面逐步擴大。結構陶瓷體的周面是波浪狀或是鋸齒狀。

An intervertebral fusion device includes a structural ceramic body. The structural ceramic body has a bottom surface, a top surface, a peripheral surface connected between the bottom surface and the top surface, and at least one pore channel penetrating the bottom surface and the top surface. The inner surface of the pore channel is either a convex curved surface or a funnel-shaped surface. For the pore channel having the convex curved surface, the pore diameter of the pore channel gradually expands from the center of the pore channel to the top surface and the bottom surface. The pore diameter can also gradually expand from the bottom surface to the top surface. The peripheral surface of the structural ceramic body is wavy or zigzag.
