Abstract
A surgical instrument and method of manipulating colon tissue of a patient includes a body having a firing mechanism, a shaft assembly, and an end effector operatively connected to the firing mechanism via the shaft assembly. The end effector is configured to receive a cartridge selectively actuated by the selective manipulation of the firing mechanism. A distal end portion of the end effector includes a first end, a second end laterally opposite the first end, and a distal crest laterally positioned between the first and second ends that projects distally beyond the first and second ends. The distal end portion also includes an arcuate distal surface extending along the distal with a radius of curvature configured to be received against the pelvic bowl of the patient to position the end effector relative to colon tissue for manipulating the colon tissue with the cartridge.
