Abstract
A surgical loading unit includes an elongate body, an end effector pivotably coupled to the elongate body, and a flexible knife bar extending through a distal portion of the elongate body and a proximal portion of the end effector. Articulation of the end effector relative to the elongate body in a first direction moves a first segment of the knife bar in the first direction and moves a second segment of the knife bar in a second direction, opposite the first direction.
