Abstract
A surgical stapler configured to clamp, staple, and cut tissue is disclosed. The surgical stapler comprises a housing, a shaft, a staple cartridge, an expandable anvil, and a distal head portion. The shaft extends from the housing and comprises three concentric actuators. The three concentric actuators are operable independently of each other. The three concentric actuators are actuatable relative to the housing and are configured to perform three separate and distinct end effector functions. The staple cartridge comprises a unitary cartridge body. The distal head portion is configured to rotate relative to the shaft. One of the separate and distinct end effector functions comprises rotating the distal head portion to expand the anvil.
