SHEATH FOR LOADING AND RECYCLING ARTIFICIAL IMPLANT, AND DELIVERY SYSTEM

Disclosed in the present application is a sheath for loading and recycling an artificial implant. The sheath comprises a body, wherein the body has in its own axial direction a distal end and a proximal end which are opposite each other; a plurality of supporting rods arranged at intervals in the circumferential direction of the body are provided at the distal end; each supporting rod has a converged state and a flared state which are relative to each other; a plurality of connecting strips are provided in the axial direction between two adjacent supporting rods; each connecting strip is folded back and forth in the converged state, and tends to straighten in the flared state relative to the converged state; and in a direction from the proximal end to the distal end, the straightening length of each connecting strip is increased in sequence, two ends of the same connecting strip are connected to the supporting rods on the corresponding sides, and connection parts have the same axial position.
