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; b) an elongated body portion extending distally from said frame portion and defining a first longitudinal axis; c) a fastener applying assembly associated with a distal end portion of said body portion, said fastener
A surgical apparatus for driving surgical fasteners comprising: a) a frame portion; b) an elongated body portion extending distally from said frame portion and defining a first longitudinal axis; c) a fastener applying assembly associated with a distal end portion of said body portion, said fastener applying assembly including: i) a base portion pivotably connected to said body portion and defining a second longitudinal axis extending therethrough; ii) a cartridge assembly mounted to said base portion, said cartridge assembly defining a proximal end portion and a distal end portion, and having a tissue engaging surface thereon, said cartridge assembly having a plurality of surgical fasteners contained therein; and iii) an anvil member mounted to said base portion and having a fastener forming surface thereon, said anvil member and said cartridge assembly being relatively movable between an open position wherein said fastener forming surface is spaced from said tissue engaging surface and a closed position wherein said fastener forming surface is in close cooperative alignment with said tissue engaging surface; d) means associated with said fastener applying assembly and actuable from said frame portion for effecting the relative movement of said anvil member and said cartridge assembly between said open and closed positions; and e) means movable through said cartridge assembly from said distal end portion thereof toward said proximal end portion thereof and actuable from said frame portion for ejecting said plurality of surgical fasteners from said cartridge assembly.
