1. A surgical method, comprising:
positioning an end effector of a surgical device in a body of a patient, the surgical device including a first elongate shaft, a second elongate shaft, a third elongate shaft, a first tube, a second tube, and a first actuator; and
actuating the first actuator, thereby causing the second elongate shaft and the first tube to move distally as a unit within a first inner lumen of the first elongate shaft and causing the third elongate shaft and the second tube to move proximally as a unit within a second inner lumen of the first elongate shaft;
wherein the movement of the second and third elongate shafts and the first and second tubes causes the end effector to articulate relative to the first elongate shaft;
the surgical device includes a first nut threadably mated with the first actuator, and the actuation of the first actuator causes the first nut to move distally and thereby cause the second elongate shaft and the first tube to move distally within the first inner lumen; and
the surgical device in a second nut threadably mated with the first actuator and the actuation of the first actuator causes the second nut to move proximally and thereby cause the third elongate shaft and the second tube to move proximally within the second inner lumen.
