Surgical stapling device with a curved end effector
First Claim
1. An end effector for use with a surgical instrument, the end effector comprising:
- a shaft portion extending along a longitudinal axis;
a first jaw, comprising;
a first intermediate portion; and
a first distal portion; and
a second jaw, wherein one of said first jaw and said second jaw comprises a plurality of staple cavities arranged in a plurality of curved staple cavity rows, wherein said second jaw is moveable relative to said first jaw between an open orientation, a partially-closed orientation, and a closed orientation, wherein said second jaw is configured to tilt laterally about the longitudinal axis, and wherein said second jaw comprises;
a second intermediate portion, wherein said second intermediate portion is brought into facing opposition with said first intermediate portion when said second jaw is moved to said closed orientation from said partially-closed orientation, and wherein said second intermediate portion is positioned a range of partially-closed intermediate distances from said first intermediate portion when said second jaw is in said partially-closed orientation; and
a second distal portion, wherein said second distal portion is positioned a partially-closed distal distance from said first distal portion when said second jaw is in said partially-closed orientation, and wherein said partially-closed distal distance is less than said distances in said range of partially-closed intermediate distances.

Abstract
An end effector for stapling and cutting tissue comprising a shaft portion extending along a longitudinal axis, a first jaw, and a second jaw is disclosed. One of the first jaw and the second jaw comprises a plurality of staple cavities arranged in a plurality of curved staple cavity rows, wherein the second jaw is moveable relative to the first jaw between an open orientation and a closed orientation. The second jaw is configured to tilt laterally about the longitudinal axis between the open orientation and the closed orientation. The second jaw comprises an intermediate portion and a distal portion, wherein the distal portion is structured to clamp tissue against the first jaw before the intermediate portion when the second jaw moves from the open orientation toward the closed orientation.
