a staple holder;
a rotational drive shaft;
a linkage operatively coupled to the staple holder and configured to expand the staple holder via an expansion motion imparted thereon;
a converter coupling intermediate the rotational drive shaft and the linkage, the converter coupling configured to convert rotational motion of the rotational drive shaft into the expansion motion of the staple holder; and
a housing that supports the linkage, converter coupling, and rotational drive shaft;
the rotational drive shaft having a stop surface engaging a corresponding surface formed in the housing to inhibit proximal translation of the rotational drive shaft relative to the housing.
