The shaft assembly includes a first shaft portion and a second shaft portion. The second shaft portion has first and second jaw members coupled to a distal end thereof. The reciprocatable drive sleeve includes a first drive-sleeve portion, slideably disposed at least partially within the first shaft portion, and a second drive-sleeve portion, slideably disposed at least partially within the second shaft portion. The surgical instrument also includes a shaft connector assembly configured to selectively couple the first shaft portion to the second shaft portion such that the first drive-sleeve portion is mechanically coupled to the second drive-sleeve portion.
