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.

Claim (Index 1):
A rooter, comprising:\n a rotatable element; and an actuator for causing the rotatable element to rotate, the actuator including:\n a distal member capable of sliding over the rotatable element, the distal member including engagement features at a proximal side thereof; and \n a proximal member capable of driving the rotatable element in a first direction, the proximal member including engagement features at a distal side thereof, the engagement features of the proximal member capable of engaging and disengaging the engagement features of the distal member, \n the engagement features of the distal member capable of engaging the engagement features of the proximal member as the distal member is forced proximally to hold the proximal member rotationally stationary and to enable the proximal member to engage the rotatable element in a manner that causes the rotatable element to rotate in a first direction, \n the engagement features of the proximal member capable of engaging the engagement features of the distal member in a manner that holds the proximal member rotationally stationary relative to the rotatable element when the rotatable element is capable of rotating in a second direction opposite from the first direction, \n the engagement features of the proximal member capable of disengaging the engagement features of the distal member to enable the proximal member to rotate about the rotatable element when the rotatable element is not capable of rotating in the second direction; \n a moveable element of a handle coupled to the distal member and capable of forcing the distal member in a proximal direction over the rotatable element and causing the distal member to engage the proximal member and force the proximal member proximally over the rotatable element to cause the rotatable element to rotate; and a biasing member for biasing the proximal member distally along the rotatable element.
