Abstract

A surgical instrument comprises a shaft, end effector and movable cutting member. The movable cutting member may comprise a first band comprising a first band slot having a distal portion and a proximal portion. A width of the first band slot at the distal portion may be larger than a width of the first band slot at the proximal portion. The movable cutting member may comprise a second band comprising a second band slot having a distal portion and a proximal portion. A width of the second band slot at the proximal portion may be larger than a width of the second band slot at the distal portion. The movable cutting member may comprise a pin positioned within the first band slot and the second band slot. The pin may comprise a middle portion having a middle portion diameter and at least one outer portion having an outer portion diameter.
