Disclosed is an apparatus for manufacturing a stent. The present invention is a perpendicularly extended rod shaped member which comprises: a center unit (10) including a center pole (11); periphery units (20) which include circular plates (21) and rotary pole moving plates (22); and moving units (30) which include rotary poles (32), wire reeling rollers (33) and wire passing rings (36). The rotary pole moving plates (22) are rotated by alternating one group which is rotated in a clock direction and the other group which is rotated in the opposite clock direction. In the circular plate (21), rotary pole tracks (211) which have 8 shaped grooves are formed. Semi-opening rotary fixing holes (221) which are opened in periphery direction are formed on the periphery of the rotary pole moving plates (22) at locations correspond to the lower part of the rotary pole tracks (211). The rotary pole fixing holes (221) are formed at locations where adjacent rotary pole moving plates are interlocked. A rotary pole (32) is inserted into the rotary fixing holes (221) on one of the rotary pole moving plates, is moved along the rotary pole track while being stood up after passing the rotary track and is moved to the rotary pole fixing holes (221) of the adjacent rotary pole moving plates (22) at locations where the rotary pole fixing holes are interlocked in order for stent fibers are weaved into a center pole. According to the present invention, stent with more accurate tension and accuracy can be possible and stent using thinner wires can be manufactured. |
