Prosthetic heart valve conveying system

The invention discloses an artificial heart valve conveying system which comprises a loading assembly and an outer sheath tube arranged outside the loading assembly in a sliding and sleeving mode, a positioning part matched with an interventional instrument connecting part is arranged in the loading assembly, and a fixing guide strip is arranged on the inner wall of the far end of the outer sheath tube. According to the interventional instrument conveying device, the near-end side which is finally released can be fastened in the release process of the interventional instrument, the interventional instrument is prevented from suddenly breaking away from the mounting position before release confirmation or in the process that the interventional instrument needs to be further withdrawn to adjust the position, and meanwhile the outer sheath tube can provide stable axial supporting and expansionary force when the interventional instrument is recycled. 本发明公开了一种人工心脏瓣膜输送系统，包括装载组件以及滑动套设在装载组件外的外鞘管，所述装载组件中带有与介入器械连接部配合的定
