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 first jaw, comprising;
a first lateral side comprising an outside radius of curvature; and
a second lateral side comprising an inside radius of curvature;
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, and wherein said second jaw comprises;
a first lateral side comprising an outside radius of curvature, wherein an outside partially-closed distance is defined between said first lateral sides when said second jaw is in said partially-closed orientation; and
a second lateral side comprising an inside radius of curvature, wherein an inside partially-closed distance is defined between said second lateral sides when said second jaw is in said partially-closed orientation, and wherein said inside partially-closed distance is less than said outside partially-closed distance; and
a cutting element structured to travel along a curved path between two curved staple cavity rows of said plurality of curved staple cavity rows.

Abstract
In various embodiments, an end effector for cutting and stapling tissue is disclosed. The end effector comprises a first jaw and a second jaw, wherein 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, and wherein the second jaw tilts and pivots toward the first jaw when the second jaw moves between the open orientation and the closed orientation. The end effector further comprises a plurality of staples removably positioned in the plurality of staple cavities.
