摘要： A mandrel is inserted into the tissue to be distracted and a filament is repeatedly wrapped around the mandrel to make a spool. As the mandrel turns, the filament coils around the mandrel to create of spool of increasing diameter. This spool can be used as a distractor, tamp, or implant. A spool implant can be cemented to further stabilize the device in situ, such as a vertebral body. The filament deposition upon the mandrel is controlled by rotation and the volume creation is incremental. This makes the spool ideal for creating highly controlled distraction forces or insertion of bulking material. In some embodiments, fibers having a low glass transition temperature are used.

摘要翻译： 将心轴插入组织以分散，并且将细丝重复地缠绕在心轴周围以制成线轴。 当心轴转动时，围绕心轴的细丝线圈产生直径增加的线轴。 该线轴可用作牵引器，夯实或植入物。 可以将线轴植入物胶合以进一步稳定装置，例如椎体。 心轴上的细丝沉积通过旋转来控制，并且体积的产生是增量的。 这使得阀芯非常适合创建高度受控的牵引力或插入膨胀材料。 在一些实施方案中，使用具有低玻璃化转变温度的纤维。
