Abstract
Apparatus and method for applying fasteners during endoscopic surgery includes a handle portion, a triggering mechanism and a fastener application. The fastener applicator is detachable from the handle portion by virtue of a rotational locking system and may be replaced with a new fastener applicator having a fresh load of vertically stacked fasteners. The fastener may be formed around a single point on an anvil. The fastener applicator having only one actuated part in its applicator mechanism, and makes use of biased springs controlled by the position of the actuated part for the remaining part of the mechanism. Another embodiment of the invention deploys a plunger/ratchet assembly and pawl within the handle portion of the apparatus to ensure that the apparatus applicator mechanism will not reverse in the middle of a triggered application stroke. A method of applying a fastener includes the following steps: moving a fastener from a storage channel, where it has been vertically stacked, to a driving channel by a biased fastener positioning spring as a slide is retracted; advancing the slide until the slide engages the fastener in the diving channel and drives the fastener over an a…
