An endoscopic surgical apparatus is provided for placing lateral lines of surgical fasteners into body tissue. The apparatus includes a frame portion, an elongated portion extending from the frame portion, and an articulating fastener applying assembly associated with a distal end of the elongated portion. The fastener applying assembly includes a base portion, a staple cartridge housing, and an anvil member which has a forming surface thereon against which surgical fasteners are driven as they are ejected from the cartridge housing. A first mechanism is provided for effectuating the rotation of the fastener applying assembly about an axis defined by the body portion, a second mechanism is provided for effectuating the articulation of the fastener applying assembly, and a third mechanism is provided for independently rotating the cartridge housing and anvil member relative to a longitudinal axis defined by the base position to increase the range of operability of the apparatus.
[ What is claimed is:] [1.]1. A surgical apparatus for driving surgical fasteners comprising:a) a frame portion;b) an elongated body portion extending distally from the frame portion and defining a longitudinal axis;c) a staple applying assembly pivotal about a pivot point adjacent a distal end of t
[ What is claimed is:] [1.]1. A surgical apparatus for driving surgical fasteners comprising:a) a frame portion;b) an elongated body portion extending distally from the frame portion and defining a longitudinal axis;c) a staple applying assembly pivotal about a pivot point adjacent a distal end of the elongated body portion, the staple applying assembly including:i) a cartridge housing;ii) a staple cartridge mounted to the cartridge housing, and having a plurality of surgical staples disposed therein; andiii) an anvil member having a staple forming surface thereon, the anvil member being movable between an open position wherein at least a portion of the staple forming surface is spaced from the staple cartridge and a closed position wherein the staple forming surface is in close cooperative alignment with the staple cartridge; andd) an articulation mechanism operatively connected to the staple applying assembly, which includes:a rotatable member; andfirst and second coupling members operatively associated with the rotatable member and the staple applying assembly, wherein rotation of the rotatable member causes the staple applying assembly to pivot from a first position having a longitudinal axis substantially aligned with the longitudinal axis of the elongated body portion to a second articulated position wherein the longitudinal axis of the staple applying assembly is positioned at an angle to the longitudinal axis of the elongated body portion.
