Electrosurgical instrument with variable control mechanisms

A surgical instrument, comprising:

• a motor assembly comprising a motor and a motor controller, wherein the motor controller is configured to operate the motor in a first operating mode and a second operating mode;
• a shaft defining a shaft axis;
• an end effector extending from the shaft, wherein the end effector is configured to perform a first end effector function and a second end effector function that is different than the first end effector function;
• a rotary drive member operably responsive to the motor, wherein the rotary drive member is operably engaged with the end effector and configured to selectively perform the first end effector function and the second end effector function;
• and
• a mode selector member operably engaged with the end effector and the rotary drive member, wherein the mode selector member is manually movable between a first position where the end effector performs the first end effector function when the rotary drive member is actuated by the motor and a second position where the end effector performs the second end effector function when the rotary drive member is actuated by the motor, wherein the motor is configured to operate in the first operating mode when the mode selector member is in the first position, and wherein the motor is configured to operate in the second operating mode when the mode selector member is in the second position.

• a lock member operably engaged with the rotary drive member, wherein the lock member is movable between a first position where the end effector is locked to the shaft and a second position where the end effector is unlocked from the shaft;
• and
• a toggle member operably engaged with the lock member, wherein the toggle member is rotatable about the shaft axis to move the lock member between the first position and the second position, wherein the rotary drive member is configured to perform the first end effector function when the lock member is in the first position, and wherein the rotary drive member is configured to perform the second end effector function when the lock member is in the second position.
