ABSTRACT:
An improved surgical stapler which allows for the multi-directional release of staples includes a stapler body and a driver contained therein. A magazine is connected to the stapler body and includes a staple track for carrying a plurality of staples wherein each of the staples has staple legs. An anvil is associated with the staple track for providing a staple forming surface for forming a staple thereon. A feeder element which is spring biased against the staples is used for feeding each staple from the staple track to the anvil. A trigger is operatively connected to the driver and is movable from a pre-fire position to a firing position for advancing the driver against the anvil for forming the staple against the anvil. A kick-off spring is positioned beneath and substantially parallel to the staple track and the anvil. The kick-off spring has a deflectable tip which is deflected away from the anvil and engages the staple legs of the staple by downwardly camming against the staple legs when the trigger is moved from its pre-fire position to its firing position. The kick-off spring ejects the staples off of and away from the anvil by disengaging the staple legs with the deflectable tip by upwardly camming against the staple legs upon returning of the trigger from the firing position to the pre-fire position.
