An elongate shaft assembly for use with a stitching device includes a hub assembly and an end effector. The hub assembly includes insertion and engaging portions. The insertion portion includes a main rod, a rotatable hub operatively coupled with the main rod such that axial displacement of the main rod rotates the rotatable hub, and first and second arms operatively coupled with the rotatable hub such that rotation of the rotatable hub causes reciprocating axial displacement of the first and second arms. The engaging portion is movable relative to the insertion portion between a reload position in which the rotatable hub is in a distal-most position and rotatable independent of axial displacement of the main rod, and a loaded position in which axial displacement of the main rod rotates the rotatable hub.
