摘要：
Improved methods and apparatuses for vertebral body distraction and fusion in accordance with various embodiments of the present invention employ one or more coaxial screw gear sleeve mechanisms. In various embodiments, coaxial screw gear sleeve mechanisms include a post with a threaded exterior surface and a corresponding sleeve configured to surround the post, the corresponding sleeve having a threaded interior surface configured to interface with the threaded exterior surface of the post and a geared exterior surface. A drive mechanism can be configured to interface with the geared exterior surface of the sleeve, causing the device to distract.
摘要（中）：
根据本发明的各种实施例的用于椎体分离和融合的改进方法和设备使用一个或多个同轴螺旋齿轮套筒机构。 在各种实施例中，同轴螺杆齿轮套筒机构包括具有螺纹外表面的柱和构造成围绕柱的相应套筒，相应套筒具有构造成与柱的螺纹外表面相接合的螺纹内表面和齿轮外部 表面。 驱动机构可以配置为与套筒的齿轮外表面连接，从而导致装置分散注意力。
