Surgical stapling device
First Claim
1. An end effector for use with a surgical instrument, the end effector comprising:
- a linear portion;
a first jaw;
a second jaw moveable relative to said first 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, and wherein said curved staple cavity rows curve in a first direction;
a curved path extending between two curved staple cavity rows of said plurality of curved staple cavity rows, wherein said curved path curves in the first direction; and
a drive assembly extending along at least a portion of said linear portion, wherein said drive assembly comprises a cutting element structured to travel along said curved path, wherein said cutting element comprises a distal pre-biased cutting edge structured to lead said cutting element in the first direction.
