18. A method for operating a surgical instrument, comprising:
articulating an end effector of the surgical instrument about an articulation joint to position the end effector relative to patient tissue;
rotating a clamp drive screw to clamp the end effector onto the patient tissue between an anvil and a staple cartridge of the end effector, wherein the staple cartridge comprises a rigid cartridge body;
gripping the patient tissue with rounded projections extending from the rigid staple cartridge body when the end effector is in a clamped configuration; and
rotating a firing drive screw to fire staples from the staple cartridge, wherein the rounded projections secure the patient tissue to prevent movement of the patient tissue when the staples are fired.
