摘要：
A surgical stapler (101) comprises a proximal end and a distal end, wherein the proximal end is proximate to the user in use and the distal end is distal from the user in use and an anvil (120, 220, 320, 420, 520, 620, 720, 820, 920, 1020, 1120, 1220, 1320) at the distal end for providing resistance to staples during the stapling operation of the surgical stapler. The anvil (120, 220, 320, 420, 520, 620, 720, 820, 920, 1020, 1120, 1220, 1320) is configured to be actuated between a deployed state and a collapsed state. The anvil (120, 220, 320, 420, 520, 620, 720, 820, 920, 1020, 1120, 1220, 1320) comprises a plurality of segments (130, 230, 330, 430, 530, 630, 730, 830, 930) arranged end-to-end. The anvil (120, 220, 320, 420, 520, 620, 720, 820, 920, 1020, 1120, 1220, 1320) is elongated in the collapsed state, the anvil (120, 220, 320, 420, 520, 620, 720, 820, 920, 1020, 1120, 1220, 1320) being elongated generally in a first direction Di. When viewed along the first direction D, the area covered by the anvil (120, 220, 320, 420, 520, 620, 720, 820, 920, 1020, 1120, 1220, 1320) is greater in the deployed state than the collapsed state. The anvil (120, 220, 320, 420, 520, 620, 720, 820, 920, 1020, 1120, 1220, 1320) is configured such that the segments (130, 230, 330, 430, 530, 630, 730, 830, 930) rotate about a rotation axis along a second direction D2 perpendicular to the first direction Di when the anvil (120, 220, 320, 420, 520, 620, 720, 820, 920, 1020, 1120, 1220, 1320) is actuated between the deployed and the collapsed states. The anvil 120, 220, 320, 420, 520, 620, 720, 820, 920, 1020, 1120, 1220, 1320 is configured such that adjacent segments 130, 230, 330, 430, 530, 630, 730, 830, 930 pivot relative to each other about a pivot axis along a third direction D3 perpendicular to the second direction D2 when the anvil (120, 220, 320, 420, 520, 620, 720, 820, 920, 1020, 1120, 1220, 1320) is actuated between the deployed and collapsed states. The stapler (101) also
