The branch trunk 210, which is continuously fed into the aortic arch branch assembly 200, enters the aortic arch outflow section 120, the first branch 220 and the second branch 230 are released to be directed toward the aortic arch part branch opening, the branch trunk 210, the third branch 240 and the blocking structure 270 are continuously released, the branch trunk 210 and the aortic arch outflow section 120 are sheathed in the cavity, the third branch 240 is directed toward the aortic arch part branch opening, and the windowing structure 260 is directed toward the distal end of the aorta. Exit the delivery device of the arch branching assembly 200. The extension of the arching branch assembly 200 is fed through the fenestration 260, the first extension 251 is disposed between the first branch 220 and the innominate artery, the second extension 252 is disposed between the second branch 230 and the left common carotid artery, the third extension 253 is disposed between the third branch 240 and the left subclavian artery, and the deployment release is performed to establish the blood flow path of the prosthesis to the branch arteries without blocking the aortic arch portion of the branch arteries. Subsequently, the blocking structure 270 is placed in the fenestration 260 to achieve the isolation integrity of the arch branching assembly 200. Finally, the descending flow section 130 of the arch is released, the conveying device of the ascending arch assembly 100 is withdrawn, a blood flow channel of the artificial blood vessel to the descending thoracic aorta is established, and finally, the isolation of aortic arch tumors is realized.
In summary, the artificial blood vessel provided by the invention comprises an arch lifting component and an arch branching component. The bow outflow section and the bow outflow section of the bow lifting assembly are respectively connected with the outlet of the inflow section. The branch trunk of the arch branch assembly is connected to the arch outflow section. The first branch, the second branch and the third branch of the arch branch assembly are respectively connected to the branch trunk, and the three interfaces are respectively connected with three extension sections. The windowing structure is arranged on the branch trunk and is blocked with a blocking structure. Through the design, the artificial blood vessel provided by the invention can be sequentially fed into the arch lifting component and the arch branch component by adopting an interventional therapy method, the arch branch component is sleeved with the arch outflow section of the arch lifting component, an isolation channel is constructed in the aortic arch cavity with neoplastic lesions, and the connection between the artificial blood vessel and the aortic arch branch is formed by arranging the extension section of the arch branch component. In addition, the plugging component can be placed in the windowing structure of the aortic arch branch component to isolate aortic arch part tumors, and simultaneously, the aortic arch part branch blood flow is not required to be blocked, so that the risk of ischemic injury to brain tissues caused by artificial blood vessel placement is reduced. In addition, the invention is suitable for being put in a multi-time sleeving manner, has lower operation risk in the putting process and is convenient for application and popularization.
