Abstract
A disposable insertion instrument for inserting an implant includes a handle assembly, a drive assembly, and a plunger assembly. The drive assembly comprises an inner shaft and a spring received within an outer sleeve. A locking pin and drive lobes on the inner shaft cooperate to reversibly lock the drive assembly in a retracted position. A medical implant may be attached to the instrument via an adapter located at a distal end of the drive assembly. Following insertion of the medical implant into a patient, the disposable insertion instrument may be discarded.
