1. A surgical tool, comprising:
a drive housing having a first end and a second end;
a spline extending between the first and second ends and being rotatably coupled to the first end at a drive input;
a drive gear coupled to and rotatable with the spline;
a carriage movably mounted to the spline and housing an activating mechanism operatively coupled to the drive gear such that rotation of the spline actuates the activating mechanism; and
a bailout mechanism arranged at the second end and including a lever, the lever being movable relative to the spline from a first position, where the spline is disengaged from the lever, to a second position, where the spline engages the lever such that rotation of the lever correspondingly rotates the spline.
