Abstract
A surgical instrument includes an articulation assembly having a dual threaded rod, a first nut, a second nut, a first articulation rod, and a second articulation rod. The dual threaded rod includes a body, a first thread encircling at least a portion of the body in a first direction, and a second thread encircling at least a portion of the body in a second, opposite direction. Rotation of the dual threaded rod in a first direction relative to the elongated portion causes the first nut to move distally relative to the dual threaded rod. Rotation of the dual threaded rod in the first direction relative to the elongated portion causes the second nut to move proximally relative to the dual threaded rod. The first articulation rod is coupled to the first nut and the end effector, and the second articulation rod is coupled to the second nut and the end effector.
