    • According to one exemplary embodiment, a pivotable interbody spacer system includes an insertion instrument configured to manipulate a pivotable interbody spacer during surgical insertion, wherein the insertion instrument includes means for coupling the interbody spacer and a means for fixing the angular position of the interbody spacer. According to one exemplary method for inserting the interbody spacer in a spinal disc space, the interbody spacer is grasped by the insertion instrument and fixed at a first angular position; the interbody spacer is inserted into the surgical site; the interbody spacer is released from the first angular position; the insertion instrument is pivoted about the coupling such that the interbody spacer is in a second angular position; the angular position of interbody spacer is fixed in the second angular position; the insertion process continues until the interbody spacer is positioned in the desired location.
    • 根据一个示例性实施例,可枢转的体间间隔器系统包括构造成在手术插入期间操纵可枢转的椎间体间隔物的插入器械,其中所述插入器械包括用于联接所述体间间隔件的装置和用于固定所述体间间隔件的角位置的装置。 根据用于将椎间盘间隔件插入脊椎盘空间的一种示例性方法,所述体间间隔物由所述插入器具夹持并固定在第一角位置; 将体间间隔件插入手术部位; 所述体间间隔件从所述第一角位置释放; 所述插入器械围绕所述联接器枢转,使得所述体间隔板处于第二角位置; 中间体间隔件的角位置固定在第二角位置; 插入过程继续进行,直到体间间隔件位于所需位置。
