An implant delivery system is disclosed which includes an inner tube assembly, an outer tube assembly and a functional handle. The functional handle includes a threaded rod (7), a push-pull control member, a casing tube (6), a displacement tube (20), an inner tube fixing member (21), an outer tube fixing member and a stability tube fixing member. The threaded rod (7) extends through a bore of the displacement tube (20). A fastener (22) of the push-pull control member is able to engage a thread provided on a leading portion of the threaded rod (7). A trailing portion of the threaded rod (7) is provided with a knob (41). The push-pull control member includes a fastener (22), springs (23) and a button (40). The fastener (22) is able to extend through a slot to engage a thread of the threaded rod (7) in the displacement tube (20). The springs (23) are configured to cause an automatic locking of the fastener (22) and the threaded rod (7). The button (40) is provided on the fastener (22). A cylindrical shell (5) drives the displacement tube (20) to move forward or backward along its longitudinal axis to cause the outer tube assembly to accordingly advance or retract. The delivery system can quickly, stably and accurately insert an implant into a target location.
