摘要：
A firing system for an applicator instrument adapted to dispense surgicalfasteners includes a housing, an elongatedshaft extending from the housing, a firing rod disposed within the elongatedshaft, a firing rod release engageable with the firingrod for preventing distal movement of the firing rod during at least one stageof a firing cycle, a trigger mounted to the housing,and a firing spring having a first end connected with the firing rod and asecond end adapted for being sequentially coupled anddecoupled from the trigger during the firing cycle. The firing cycle includesan initial stage in which the trigger is open and decou-pledfrom the energy storing element, and the firing spring is at least partiallycompressed, and a piloting stage during which thefiring rod release is disengaged from the firing rod for enabling distalmovement of the firing rod.
