Abstract
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, a push-pull control member, a casing tube, a displacement tube, an inner tube fixing member, an outer tube fixing member and a stability tube fixing member. The threaded rod extends through a bore of the displacement tube. A fastener of the push-pull control member is able to engage a thread provided on a leading portion of the threaded rod. A trailing portion of the threaded rod is provided with a knob. The push-pull control member includes a fastener, springs and a button. The fastener is able to extend through a slot to engage a thread of the threaded rod in the displacement tube. The springs are configured to cause an automatic locking of the fastener and the threaded rod. The button is provided on the fastener. A cylindrical shell drives the displacement tube 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.
