Abstract

An end effector for a surgical stapler. Various embodiments include a channel configured to operably support a staple cartridge therein. A first tip portion is attached to or formed on a distal end of one of the channel and staple cartridge wherein the first tip portion may have a first upwardly extending curved outer surface. An anvil is movably coupled to the channel and is selectively movable between open and closed positions relative to the staple cartridge in response to opening and closing motions applied to the anvil. A second tip portion is attached to or formed on a distal end thereof. The second tip portion may have a second downwardly extending curved surface such that when the anvil is in the closed position, the second tip portion cooperates with the first tip portion to define a blunt end effector nose. In various embodiments, the end effector nose has a substantially paraboloid outer surface.
