Abstract

A surgical device includes a shaft portion coupled to a handle, the handle defining a longitudinal axis. The surgical device also includes a first driver configured to actuate a rotational movement via a first drive shaft and a second driver configured to actuate an articulation movement via a second drive shaft. The surgical device also includes a controller having a first dial and a second dial, the first dial actuated by the first driver and the second dial actuated by the second driver, the second dial positioned within the first dial.
