Abstract
An end effector includes a substantially U-shaped stationary jaw located distally and a movable jaw movable relative to the stationary jaw to clamp tissue therebetween. The stationary jaw includes an anvil. The movable jaw is configured to receive a staple cartridge. A surface of the anvil opposite to the movable jaw defines a tissue engagement surface that defines a longitudinal axis and includes first and second staple forming pocket pairs located at two sides of the longitudinal axis. The first staple forming pocket pair and the second staple forming pocket pair each are configured as a centrosymmetric structure formed by two staple forming pockets arranged along the longitudinal axis. The staple forming pocket has an asymmetric shape. Corresponding staple forming pockets in the first and second staple forming pocket pairs are opposite to each other in shape orientation along a transverse direction perpendicular to the longitudinal axis.
