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: 14
Claim 1
Independent Claim
129 words
A surgical apparatus for applying surgical fasteners comprising: a body portion defining a first longitudinal axis; and a fastener applying assembly rotatably and pivotally supported on a distal end of the body portion and defining a second longitudinal axis, the fastener applying assembly including a cartridge assembly and an anvil member, the anvil member being movable in relation to the cartridge assembly between an open position and a clamped position, the fastener applying assembly being pivotal from a first position in which the second longitudinal axis is substantially aligned with the first longitudinal axis to a second position in which the second longitudinal axis is angularly disposed from the first longitudinal axis, and the fastener applying assembly being rotatable about the second longitudinal axis independently of the body portion.
Claim 2
Dependent Claim
129 words
A surgical apparatus for applying surgical fasteners comprising: a body portion defining a first longitudinal axis; and a fastener applying assembly rotatably and pivotally supported on a distal end of the body portion and defining a second longitudinal axis, the fastener applying assembly including a cartridge assembly and an anvil member, the anvil member being movable in relation to the cartridge assembly between an open position and a clamped position, the fastener applying assembly being pivotal from a first position in which the second longitudinal axis is substantially aligned with the first longitudinal axis to a second position in which the second longitudinal axis is angularly disposed from the first longitudinal axis, and the fastener applying assembly being rotatable about the second longitudinal axis independently of the body portion.
Claim 3
Dependent Claim
22 words
