SURGICAL INSTRUMENT HAVING A FASTENER DELIVERY MECHANISM

摘要

A delivery device for delivering a plurality of fasteners, said delivery device comprising: a handle; a drive and indexing mechanism having proximal and distal ends, the driving and indexing mechanism operatively associated with the handle and comprising a moving member, having a sharp distal end for piercing tissue, and an elongate member spaced transversely from the moving member to define a passageway there between, the drive and indexing mechanism being configured to receive a plurality of fasteners arranged along the passageway between the moving member and the elongate member, each of the plurality of fasteners having a proximal end and a distal end, the moving member and the elongate member being moveable proximally and distally with respect to the handle and with respect to each other for delivering and indexing the fasteners along the passageway; and an actuator having at least two sequential positions, a first position wherein the moving member has been moved distally relative to the handle to pierce tissue, and a second position wherein the moving member has been moved proximally relative to the handle for completing the deployment within tissue of the distal end of a distal-most fastener from the passageway.
