Beschreibung
Zusammenfassung:	The invention relates to a vascular stent structure. The structure comprises two first diameter segments 1, a second diameter segment 2 and two arc segments 3, the diameter of the first diameter segment is smaller than the diameter of the second diameter segment, and the arc segments are symmetrically arranged about the second diameter segment; the structure is characterized in that each arc segment comprises multiple first annular support ribs and multiple first connecting ribs, wherein the first connecting ribs and the first annular support ribs are arranged in wavy structures in the circumferential direction, wave peak segments of the wavy structures are provided with first connecting ribs, wave troughs of the wavy structures are provided with first connecting ribs, the adjacent first annular support ribs are connected through the first connecting ribs, and the wave troughs close to the first diameter support ribs of the first diameter segments are connected with the first connecting ribs through connectin
