Abstract
A surgical instrument includes a shaft defining a longitudinal axis therethrough and having an end effector assembly disposed at a distal end thereof. The shaft includes first and second shaft components that are releasably engageable with one another. A drive sleeve is disposed within the shaft and is longitudinally translatable relative to the shaft to transition the end effector assembly between a first state and a second state. The drive sleeve includes first and second drive sleeve components that are releasably engageable with one another. A coupling mechanism includes one or more shaft cantilever springs configured to releasably engage the first and second shaft components to one another and one or more drive sleeve cantilever springs configured to releasably engage the first and second drive sleeve components to one another.
