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 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, and wherein said second jaw comprises;
a second intermediate portion, wherein said second intermediate portion is positioned a partially-closed intermediate distance 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 partially-closed intermediate distance.

Abstract
The present invention includes a surgical stapler having a staple cartridge, an anvil, and a cutting member having a cutting surface, wherein the cutting member is relatively movable with respect to the anvil and the staple cartridge. In at least one embodiment, one of the anvil and the staple cartridge defines a slot which is configured to receive at least a portion of the cutting member and guide the cutting member as it is moved relative to the anvil and the staple cartridge. In these embodiments, the slot can define a path having linear and/or curved portions. In various embodiments, the path can include a curved portion having a first portion that extends away from the shaft axis and a second portion that extends toward the axis. In one embodiment, the path can include a curved portion defined by an arc corresponding to an angle greater than 90 degrees.
