Abstract
本发明涉及气道支架技术领域，具体为一种生物可降解气道支架，包括主体支架结构，所述主体支架结构由径向架和横向架组成，有益效果为：通过在主体支架结构内部设置外固架和内固架，内固架通过螺旋安装条与外固架内部螺旋安装架螺旋安装组合，螺旋纹理可以增加外固架与内固架的摩擦力，减少移位的风险，在螺旋安装条和螺旋安装架之间涂覆一层可降解的生物粘合胶，可以在降解过程中逐渐分解，但仍然保持一定的黏附力，直到可生物降解支架完全降解，外固架表面均匀分布生长附着微孔，以利于组织细胞的长入和营养物质的交换，使得外固架受到的应力可以通过微孔结构在多个方向上分散，通过螺旋组合和微孔结构组合，可以有效减少应力集中。
