MOTOR DRIVEN SURGICAL INSTRUMENTS WITH LOCKABLE DUAL DRIVE SHAFTS
First Claim
1. A surgical instrument, comprising:
- a motor including a motor output shaft;
a first rotary drive system;
a second rotary drive system;
a transmission assembly in operable engagement with the motor output shaft and being selectively shiftable between a first drive position wherein rotation of the motor output shaft is imparted to the first rotary drive system and a second drive position wherein rotation of the motor output shaft is imparted to the second rotary drive system; and
a locking assembly supported by the transmission assembly and configured to mechanically prevent actuation of the second rotary drive system when the transmission assembly is in the first drive position, said locking assembly further configured to prevent actuation of the first rotary drive system when the transmission assembly is in the second drive position.

Abstract
Motor driven surgical instruments that include a first rotary drive system and a second rotary drive system. Various forms include a transmission assembly that is selectively shiftable between a first drive position wherein rotary motion generated by the motor is transferred to the first rotary drive system and a second drive position wherein rotary motion generated by the motor is transferred to the second rotary drive system. Various forms further include a locking assembly configured to mechanically prevent rotation of the second rotary drive system when the transmission assembly is in the first drive position as well as to prevent rotation of the first rotary drive system when the transmission assembly is in the second drive position.
