With slips set inside the joint and the string hanging free, rotating the top drive rotates the string as the string is lowered. With slips again supporting the string on the rig floor the top drive can be rotated in an opposed direction with weight set down to back off the slips and to remove it from the top joint.

The cradle drive mechanism also includes a cradle connector fixed on the transmission belt and configured to connect a cradle and to drive linear reciprocating motion of the cradle.

Abstract: Methods and systems for micro transmissions for a micro machine may comprise an input shaft assembly coupled to a micro actuator, an output shaft assembly coupled to a micro shaft, and one or more power conversion elements operable to convert a first type of movement from the micro actuator into a second, disparate type of movement for the micro shaft.
Abstract: A surgical instrument, in at least one form, includes an end effector and a power module. The power module may include a first motion conversion assembly. The first motion conversion assembly includes a first rotary drive and a first axial drive operably coupled to the first rotary drive. The power module may further include a second motion conversion assembly which may include a second rotary drive and a second axial drive operably coupled to the second rotary drive. The power module may further include a motor configured to generate at least one rotational motion to actuate the end effector and a transmission assembly configured to selectively engage the motor with the first rotary drive and the second rotary drive, wherein the motor is concentrically arranged with the first rotary drive and the second rotary drive.
