环面修复系统、器械和技术
摘要：
修复环面缺损的系统和方法，包括至少一个可放置入或邻近环面缺损的封闭元件(50，150)，和至少一个将封闭元件(50，150)固定于陷入相邻椎骨的邻近组织的锚(70，80，170，180)。封闭元件(50，150)至少部分延伸跨过环面缺损以修复缺损和/或保留核材料、一种或多种植入物、生物相容材料或器械和/或其它放置于盘间隙的物质。提供了器械以便于准备环面修复系统的植入部位。
摘要（英）：

Systems and methods for repairing annulus defects include at least one blocking member (50, 150) positionable in or adjacent to the annulus defect, and at least one anchor (70, 80, 170, 180) for securing the blocking member (50, 150) to adjacent tissue recessed into the adjacent vertebrae. The blocking member (50, 150) extends at least partially across the annulus defect for repair of the defect and/or retention of nucleus material, one or more implants, bio-compatible materials or device, and/or other objects positioned in the disc space. Instruments are provided to facilitate preparation of the implantation site of the annulus repair system.
