Abstract
一种栓塞保护装置(100)，包括边框(110)、边过滤网(120)和间隔设置的多个支撑杆(130)，支撑杆(130)包括第一末端(131)、第二末端(131)和至少一个朝向远端的头端(132)，第一末端(131)和第二末端(131)分别连接在边框(110)的相对两侧，第一末端(131)、第二末端(131)分别与头端(132)形成第一线段(V1)、第二线段(V2)，第一线段(V1)从第一末端(131)朝向头端(132)的方向延伸并逐渐远离边框(110)，第二线段(V2)从第二末端(131)超向头端(132)的方向延伸并逐渐远离边框(110)，使多个支撑杆(130)将覆盖在多个支撑杆(130)上的边过滤网(120)朝向远离边框(110)的方向撑起。该装置无需借助鞘芯即可将边过滤网贴合在主动脉弓的三个分支处，且在实际应用中，边框和支撑杆相互作用、相互促进，促使边框在主动脉弓处稳固的固定，还使各个支撑杆给予过滤网更大的向上支撑力，进而使边过滤网更好地贴合主动脉弓。
