    • A nuclectomy system for creating a nuclear cavity located in an intervertebral disc space and for preparing the nuclear cavity to receive an intervertebral prosthesis. An opening through the annulus is formed along an annular axis to provide access to a nucleus. A portion of the nucleus is removed in a first region surrounding the annular axis using at least a first surgical tool. Another portion of the nucleus is removed from a second region using at least a second surgical tool. An evaluation mold is positioned in the nuclear cavity and a fluid is delivered to the evaluation mold so that the mold substantially fills the nuclear cavity. The amount of nucleus removed is estimated. One or more of the removing steps are optionally repeated as necessary until an adequate amount of the nucleus is removed.
    • 一种用于产生位于椎间盘空间中并用于准备核腔以接收椎间假体的核腔的核结肠切除术系统。 沿着环形轴线形成通过环的开口以提供通向核的通路。 至少使用第一外科手术工具,在包围环形轴的第一区域中移除核的一部分。 使用至少第二外科手术工具从第二区域移除细胞核的另一部分。 评估模具定位在核腔中,并将流体输送到评估模具,使得模具基本上填充核腔。 估计去除核的量。 任选地根据需要重复一个或多个除去步骤,直到去除足够量的细胞核。
