髓核假体
摘要：
髓核假体(30)包括多个节(32)，所述节包括前部节和尾部节，以及联接所述节的至少一个连接，该假体具有打开位置，在该位置所述节沿连接以串联线设置，其中在串联线的一端具有前部节并在串联线的另一端具有尾部节；以及闭合位置，在该位置所述节被设置以形成前部节和尾部节基本并置的盘形。所述节之间的连接是铰链(34a)，该铰链联接并且自由地铰接所述节以便于髓核假体的打开和闭合。
摘要（英）：

A nucleus prosthesis (30) comprising a plurality of segments (32), including a leading segment and a trailing segment, and at least a linkage (34) coupling the segments, the prosthesis having an open position in which the segments are disposed along the linkage in a serial line with the leading segment at an end of the serial line and the trailing segment at another end of the serial line; and a closed position in which the segments are disposed to form a disc shape with the leading segment and the trailing segment substantially apposed. The linkage between the segments is a hinge (34a) coupling and freely articulating the segments so as to facilitate the opening and closing of the nucleus prosthesis.
