A self contained gas powered 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 self contained pneumatic system is associated with the frame portion and is actuable to eject the surgical fasteners from the cartridge assembly. 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.
A surgical apparatus for driving surgical fasteners comprising: a) a frame portion defining a longitudinal axis; b) an elongated body portion extending distally from said frame portion; c) a fastener applying assembly operatively associated with a distal end portion of said body portion and includin
A surgical apparatus for driving surgical fasteners comprising: a) a frame portion defining a longitudinal axis; b) an elongated body portion extending distally from said frame portion; c) a fastener applying assembly operatively associated with a distal end portion of said body portion and including; i) a cartridge member containing a plurality of surgical fasteners; and ii) an anvil member mounted adjacent said cartridge member, said cartridge member and said anvil member being relatively movable between an open position and a closed position; d) fastener ejection means actuable from said frame portion for sequentially ejecting said plurality of surgical fasteners from said cartridge member to be driven against said anvil member; e) a pneumatic actuation system disposed within said frame portion and operatively associated with said fastener ejection means, said pneumatic actuation system including: i) a canister of compressed gas having a fixed longitudinal orientation with respect to said frame portion; and ii) a valve member configured to communicate with said canister of compressed gas; and f) an actuation assembly including a pivotable link, said link being movable to cause said valve member to move relative to said canister to effect communication therebetween and cause gas to be expelled from said canister to actuate said fastener ejection means.
