Abstract
Abstract 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.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
137 words
A fastener applying assembly comprising: an anvil member; a cartridge assembly movably positioned in relation to the anvil member between open and approximated positions, the cartridge assembly including a staple cartridge having a plurality of staples, wherein the cartridge assembly is pivotal in relation to the anvil member from the open position to the approximated position; a staple ejecting assembly associated with the cartridge assembly, the staple ejecting assembly including at least one cam member, the at least one cam member being configured to translate from a position adjacent a distal end of the staple cartridge towards the proximal end of the staple cartridge to sequentially eject the plurality of staples from the staple cartridge; and an approximation link connected to the cartridge assembly by a pivot pin and to the anvil member by a cam pin.
Claim 2
Dependent Claim
137 words
A fastener applying assembly comprising: an anvil member; a cartridge assembly movably positioned in relation to the anvil member between open and approximated positions, the cartridge assembly including a staple cartridge having a plurality of staples, wherein the cartridge assembly is pivotal in relation to the anvil member from the open position to the approximated position; a staple ejecting assembly associated with the cartridge assembly, the staple ejecting assembly including at least one cam member, the at least one cam member being configured to translate from a position adjacent a distal end of the staple cartridge towards the proximal end of the staple cartridge to sequentially eject the plurality of staples from the staple cartridge; and an approximation link connected to the cartridge assembly by a pivot pin and to the anvil member by a cam pin.
Claim 3
Dependent Claim
32 words
A fastener applying assembly according to claim 1 , wherein the staple ejecting assembly includes a knife blade adapted to translate with the at least one cam member to divide stapled tissue.
Claim 4
Dependent Claim
37 words
A fastener applying assembly according to claim 2 , further including a shank positioned distally of the at least one cam member, the shank being adapted to translate with and behind the at least one cam member.
Claim 5
Dependent Claim
