Claim 5:
6. A surgical device, comprising:
an elongate shaft extending distally from a proximal handle portion;
an end effector configured to move between an unarticulated position, in which the end effector is not articulated relative to the elongate shaft, and an articulated position, in which the end effector is articulated relative to the elongate shaft;
an actuator configured to be rotated in a first direction with the end effector in the unarticulated position and thereby cause the end effector to move from the unarticulated position to the articulated position, wherein continued rotation of the actuator in the first direction is configured to cause the end effector to move from the articulated position to the unarticulated position;
first and second movable members that are engaged with the actuator and operatively coupled to the end effector such that the rotation of the actuator in the first direction causes axial translation of the first and second movable members to thereby move the end effector from the articulated position to the unarticulated position and from the unarticulated position to the articulated position; and
wherein, with the end effector in the unarticulated position, the first and second movable members are threadably engaged with the actuator; and the continued rotation of the actuator in the first direction is configured to cause the first and second movable members to become threadably disengaged from the actuator.
