Abstract:
A hand held, hand operated apparatus for rotating, or spinning, rotatably oscillating and/or inducing back and forth longitudinal movement in a device, such as an elongated medical device. A drive shaft of the hand held, hand operated rotational drive apparatus includes a ratcheting mechanism capable of enabling oscillating (repeated forward and reverse) rotation of a device that has been coupled thereto when there is little or no resistance on the rotated device, and of enabling an actuator to return to a position that will enable further forward, or driving, rotation of the drive shaft and the rotated device when resistance on the rotated device prevents the rotated device and the drive shaft from rotating in a reverse direction.
