摘要:
An expandable fusion cage has an elongated cage body with a central hollow region, a posterior end and an anterior end with first and second anterior end portions in communication with the central hollow region, a first longitudinal member and a second longitudinal space from and substantially parallel to the first longitudinal member extending between the posterior end and the first anterior end portion, and a cam body having a cam surface on a periphery of the cam body and a cam adjusting feature facing the central hollow region where the cam body is positioned between the first anterior end portion and the second anterior end portion and is adapted to rotatably engage the cam surface with the first anterior end portion and the second anterior end portion to change the orientation of the anterior end of the cage body between a collapsed configuration and an expanded configuration.
摘要(中):
可扩展的融合笼具有细长的笼体,其具有中心空心区域,后端和前端,其具有与中心空心区域连通的第一和第二前端部分,第一纵向构件和第二纵向空间,并且基本上平行 涉及在后端和第一前端部分之间延伸的第一纵向构件,以及在凸轮本体的周边具有凸轮表面的凸轮体,以及面对中心空心区域的凸轮调整特征,凸轮本体位于 第一前端部分和第二前端部分,并且适于将凸轮表面与第一前端部分和第二前端部分可旋转地接合,以改变笼体的前端在收缩构型和扩张之间的取向 组态。
