Title: CONVEYING SYSTEM FOR IMPLANT
Abstract:
Provided is a conveying system (100) for an implant (200), the conveying system comprising an inner sheath tube (11), an inner sheath core tube (13) penetrating the inner sheath tube (11) and a distal end thereof extending out from the inner sheath tube (11), and an outer sheath tube (12) movably sheathed outside the inner sheath tube (11) and having a cavity from the inner sheath core tube (13). The conveying system (100) further comprises at least one hook unit (20) fixed on an outer surface of the inner sheath core tube (13), wherein the hook unit (20) comprises at least two flexible hook members (22), each of the hook members (22) comprises a fixing part (221) connected to the outer surface of the inner sheath core tube (13) and a deformation part (222) connected to the fixing part (221), and a free end of the deformation part (222) can be bent relative to the fixing part (221), and when accommodated in a cavity between the outer sheath tube (12) and the inner sheath core tube (13), the free end matches the fixing part (221) to form a hook-shaped object. The implant (200) is fixed to the inner sheath core tube (13) via the hook unit (20), limiting the movement of the implant (200). Thus, during the conveying process of the implant (200), the displacement of the implant (200) does not occur with respect to the inner sheath core tube (13). In addition, during the release process, when it is needed to adjust a release position of the implant (200), a release in advance of the implant (200) can be avoided.
