摘要：
abstract of the disclosure a rotary drive arrangement for a surgical instrument that includes a surgical end effector. In one form, the rotary drive arrangement includes a drive shaft assembly that is selectively axially movable between a first position and a second position. a rotary transmission operably interfaces with the drive shaft assembly such that when the drive shaft assembly is in the first axial position, application of one of the rotary drive motions to the drive shaft assembly causes the rotary transmission to apply a first rotary control motion to the surgical end effector and when the drive shaft assembly is in the second axial position, application of the rotary drive motion to the drive shaft assembly causes the rotary transmission to apply a second rotary control motion to the surgical end effector. ____________________________________________________________________ Summary of the invention "Swivel drive arrangements for surgical instruments" A swivel drive arrangement for a surgical instrument including a surgical end actuator is disclosed. In one form, the rotary drive arrangement includes a drive rod assembly that is selectively capable of axially moving between a first position and a second position. a rotary drive forms an operational interface with the drive rod assembly so that when the drive rod assembly is in the first axial position, applying one of the rotary drive motions to the drive rod assembly causes the rotary drive applies a first rotary control motion to the surgical end actuator, and when the drive rod assembly is in the second axial position, applying the rotary drive motion to the drive rod assembly causes the rotary drive to apply a second rotary control movement to the surgical end actuator.abstract of the disclosure a rotary drive arrangement for a surgical instrument that includes a surgical end effector. in one form, the rotary drive arrangement includes a drive shaft assembly that is selectively axially movable between
