Zusammenfassung:The invention provides a combined stent, and relates to the technical field of medical instruments, the combined stent comprises a first stent and a second stent which are axially connected, the first stent is a dense net stent, and the second stent is a cutting stent comprising an open-loop structure. Wherein a first connecting part is arranged at the near end of the first support, a second connecting part is arranged at the far end of the second support, and the first connecting part and the second connecting part are connected in a buckled mode. The scheme that the cutting stent with the open-loop structure is arranged at the near end of the dense mesh stent is adopted, the mesh density of the near end of the blood flow guiding device is reduced, and meanwhile the blood flow guiding effect and the near-end supporting effect of the dense mesh stent are not affected; the blood flow blocking effect on branch blood vessels after the dense net stent is implanted can be reduced, and the problem of insufficient c
