1. A surgical tool, comprising:

  • a housing having a plurality of motor-driven drive gears;

    an elongate shaft extending distally from the housing;

    an end effector coupled to a distal end of the elongate shaft;

    at least first and second actuation assemblies, each actuation assembly being coupled to one of the plurality of motor-driven drive gears such that each of the motor-driven drive gears is configured to drive a corresponding actuation assembly, the first actuation assembly being configured to operate a first function of the end effector, and the second actuation assembly being configured to operate a second function of the end effector that is different than the first function; and

    at least first and second bailout mechanisms, the first bailout mechanism being selectively engageable with the first actuation assembly and being configured to be manually driven to subsequently drive the first actuation assembly, and the second bailout mechanism being selectively engageable with the second actuation assembly and being configured to be manually driven to subsequently drive the second actuation assembly, the first bailout mechanism including a first one-way gear, the second bailout mechanism including a second one-way gear, each of the first and second one-way gears being configured to be rotatable in only one direction to drive the corresponding first and second actuation assembly.
