1. An endoscopic instrument, comprising:
a housing;
a shaft assembly configured to couple to the housing and including an inner shaft member and an outer shaft member movable relative to the inner shaft member, the inner shaft member defining a slot and the outer shaft member defining a slot;
a bushing operably coupled to the inner and outer shaft members of the shaft assembly and selectively and releasably coupled to the housing, the bushing including at least one resilient finger configured to engage the slot of the inner shaft member and the slot of the outer shaft member; and
a spring carrier operably supported within the housing and including at least one resilient boss configured to releasably engage a second slot defined through the outer shaft member, the at least one resilient boss being disengaged from the second slot to release the inner and outer shaft members from the housing when the outer shaft member is rotated with respect to the spring carrier.
