Claim 0:
1. An implant delivery tube assembly for loading and delivering an implant, the implant delivery tube assembly comprising:
an outer tube; and
a capsule sequentially arranged from a proximal end to a distal end thereof,
wherein an inner cavity of the capsule is adapted to receive the implant,
wherein the capsule is located at the distal end of the outer tube,
wherein the capsule has a telescopic structure, and the outer tube is configured to drive the capsule to perform a telescopic movement by extending or retracting the capsule,
wherein the capsule comprises at least two capsule segments that are sequentially sleeved, and any two adjacent capsule segments are movably connected to form a cylindrical telescopic structure,
wherein the at least two capsule segments comprise at least a distal capsule segment and a proximal capsule segment, an inner diameter of the distal capsule segment is greater than an inner diameter of the proximal capsule segment, and when the capsule is fully extended, a distal end of the distal capsule segment is at a most distal end of the capsule, and a proximal end of the proximal capsule segment is at a most proximal end of the capsule, and
wherein a proximal end of the distal capsule segment is attached to or integrally formed with the distal end of the outer tube, wherein the outer tube is configured to drive the distal capsule segment to move, the distal capsule segment being configured to drive other capsule segments to move, thereby realizing the telescopic movement of the capsule.
