1. A method of manually operating a surgical tool, comprising:
arranging the surgical tool adjacent a patient, the surgical tool including:
a drive housing having opposing first and second ends;
a spline extending between the first and second ends and being rotatably coupled to a drive input at the first end;
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 engageable with the spline;
moving the lever 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; and
manually rotating the lever and thereby rotating the spline and the drive gear to manually actuate the activating mechanism.
