椎体修复组件Vertebral body repair components

技术领域technical field

本发明属于脊柱修复技术领域，更具体地说，是涉及一种椎体修复组件。The invention belongs to the technical field of spinal repair, and more particularly relates to a vertebral body repair component.

背景技术Background technique

在脊柱手术中，经常会破坏椎体表面的椎板、棘突、小关节等结构，在这些结构被破坏后，目前并没有较好的复原手段，通常不进行修复，但是，不进行修复，手术效果难以达到最佳。若采用传统的骨修复方法，通过植入钢板或其他替代物进行修复，由于被破坏的结构较小且位于椎体表面，不仅难以将钢板或其他替代物与椎体进行固定，而且也难以还原被破坏部分的形状，同样难以使手术效果达到最佳。In spine surgery, structures such as the lamina, spinous process, and facet joints on the surface of the vertebral body are often damaged.
