A surgical stapler includes a proximal end and a distal end and an anvil at the distal end for providing resistance to staples during the stapling operation of the surgical stapler. The anvil may include a number of segments arranged end-to-end. The anvil is elongated in the collapsed state, the anvil being elongated generally in a first direction D. The anvil is configured such that the segments rotate about a rotation axis along a perpendicular second direction Dwhen the anvil is actuated between the deployed and the collapsed states. The anvil is configured such that adjacent segments pivot relative to each other about a pivot axis along a third direction Dwhen the anvil is actuated between the deployed and collapsed states. The stapler also includes an actuator mechanism, wherein the actuator mechanism is configured to be controlled from a location on the surgical stapler towards the proximal end.
