Abstract
An apparatus for selectively advancing and/or rotating an elongate device, includes a carrier mounted for rotation about a primary axis and a pair of opposed rollers on the carrier adapted to drive the device in a direction along the primary axis. A mechanism drives at least one of the rollers has a first gear and a second gear. A first input selectively rotates the second gear in first or second directions to advance or retract the elongate device. A second input selectively rotates the carrier in first and second directions to rotate the elongate device. The operation of the second input alone simultaneously rotates and advances/retracts the elongate device, and the coordinated operation of the first and second inputs rotates the elongate device without advancement/retraction.
