Claim:
1. A deployment mechanism for selectively deploying and retracting at least one of an energizable member or an insulative member relative to an end effector assembly of a surgical instrument, the deployment assembly comprising: at least one actuator rotatable in a first direction from an un-actuated position to an actuated position and rotatable in a second direction from the actuated position back to the un-actuated position; a clutch assembly associated with the at least one actuator, the clutch assembly configured to couple to the at least one actuator to provide rotational motion in the first direction in response to rotation of the at least one actuator in the first direction, the clutch assembly configured to decouple from the at least one actuator in response to rotation of the at least one actuator in the second direction; and a drive assembly operably coupled to the clutch assembly and the at least one of the energizable member or the insulative member, the drive assembly configured to convert the rotational motion provided by the clutch assembly into longitudinal motion to translate the at least one of the energizable member or the insulative member from a storage position to a deployed position and to translate the at least one of the energizable member or the insulative member from the deployed position back to the storage position.
