Device for spinous process

The subject innovation relates to an expansion device between the vertebral spinous process for expanding the narrowed gap between the spinous process of the spine. Expansion device between the vertebral spinous process according to an embodiment of the subject innovation is an upper support for supporting the vertebral spinous process is located at the upper spinous process of the spine adjacent to each other; Habuji portion for supporting the vertebral spinous process is located at the bottom of the vertebral spinous process to the next to each other; And a second connecting portion for connecting the upper support part and the crosspiece are arranged spaced from each other between the habuji portion, the first connection and, and the other side with the habuji portion of the bar connecting the upper support part and the one side of the bar includes; connection comprising. Therefore, even after the procedure it may be free to move the body, by distributing the load it is possible to prevent breakage of the expansion device between the vertebral spinous process and the vertebral spinous process.
