1. A stent that prevents its own migration, comprising: a hollow cylindrical body made of metal wire, the first blocking parts protruding outward from the body； and second blocking parts formed at a distance from the first blocking parts in the longitudinal direction of the body in a symmetrical manner with respect to the first blocking parts around a vertical surface with respect to the longitudinal direction of the body. 2. A stent according to claim 1, wherein a plurality of at least one of the first blocking parts and the second blocking parts are formed. The stent according to claim 2, in which at least one of the first blocking parts and the second blocking parts are located at the same distance from each other along the outer peripheral surface of the body to form a row, and at least one or more rows are formed along longitudinal direction of the body. 4. The stent according to claim 3, in which the first blocking parts and the second blocking parts are formed with an inclination with respect to the outer peripheral surface of the body. The stent according to claim 4, in which at least one of the first blocking parts and the second blocking parts extend from a portion of the metal wire forming the body, or protrude from the outer periphery of the body by a separate metal wire. A device for manufacturing a stent that prevents its own migration, comprising: a clamping part having a cylindrical body prepared for the manufacture of a stent, and at least one or more mounting recesses formed on the outer peripheral surface of the body； supporting fingers configured to be inserted into fasteners�1. Стент, предотвращающий собственную миграцию, содержащий:полое цилиндрическое тело, изготовленное из металлической проволоки；первые блокирующие части, выступающие наружу из тела； ивторые блокирующие части, сформированные на расстоянии от первых блокирующих частей в продольном направлении тела в симметричном отношении по отношению к первым блокирующим частям вокруг вертикал
