ABSTRACT:
A method and apparatus for storing and automatically dispensing and applying surgical staples in serial fashion includes a pistol-like tool having means for storing a large plurality of staples in parallel, stacked column fashion aligned along the longitudinal (barrel) axis of the tool. A form tool and an anvil tool extend longitudinally parallel to the axis, and are advanced in synchronism by actuation of a trigger lever. The form tool includes a pair of arms which impinge upon and rotate the legs of the staple about the web portion thereof to dispose the staple in a points-first dispensing orientation. The form tool advances the staple to the distal dispensing end of the tool, where it drives the staple into a portion of the anvil and crimps the staple thereabout. Release of the trigger causes an elevator member to separate the next distal staple inthe column from its column alignment into postion to be engaged by the anvil tool and form tool at the start of the subsequent dispensing cycle. A trigger actuation mechanism prevents release of the trigger lever until the dispensed staple is completely crimped in the tissue.
