The invention relates to a covered stent conveying and far-end positioning releasing system. A stent conveying mechanism comprises a core pipe assembly composed of a liquid filling port, a core pipe and a guide head, a middle pipe assembly composed of a middle pipe and a second control handle, and a sheath pipe assembly composed of a sheath pipe and a first control handle. A stent far-end positioning releasing mechanism comprises a guide wire, a guide wire rewinding system and a guide wire pulling ring. A stent and the guide wire are bundled and compressed in a stent loading area of the stent conveying mechanism through a stent bundling line. After the stent conveying mechanism conveys the stent to the designated position, the middle pipe assembly and the core pipe assembly are mixed, the sheath pipe is retreated till the stent is completely exposed, the guide wire pulling ring is unscrewed, the guide wire is slowly pulled backwards, the guide wire is retreated through the guide wire rewinding system and moves from the far end to the near end of the stent, the guide wire and a stent bundling line winding point are disengaged in sequence along with retreating of the guide wire, the stent is automatically bounced off and released after being disengaged from the stent bundling line, finally, positioning releasing of the stent from the far end to the near end is achieved, and positioning precision is improved.
