New description: [New technical field] This creation provides a technique for injecting hollow bone nails into bones. A's technically provides a multi-directional bone-soil perfusion hollow bone nail. And effectively injecting the bone mud into the loose vertebral body, and can appropriately adjust the angular deviation caused by the deviation of the nail insertion during assembly, and greatly increase the interface strength between the bone nail/bone to achieve the purpose of strengthening postoperative stability. . [Prior Art] According to the fact, for patients with severe osteoporosis, the effective fixation of the spinal nail is a major test in spinal surgery. The commonly used method is to first re-lock the bone nail after injecting the bone mud into the vertebral body to improve the interfacial strength of the nail, but often it is impossible to adjust the restriction of the locking direction of the nail because the traditional bone nail is unidirectional. Or because of insufficient bone perfusion, the steel nails, bone mud and vertebral body can not be well combined, resulting in the inability of the spinal steel nails to be effectively fixed. For patients with severe osteoporosis, in order to strengthen the interface strength between the nail and the bone tissue, there is a national company's heart at this stage.
