Abstract: A system and method of operating a minimally invasive cutting instrument includes a surgical cutting instrument. The surgical cutting instrument includes a drive unit, an end effector located at a distal end of the instrument, and a garage for housing the cutting blade when the cutting blade is not in use. The end effector includes gripping jaws and a cutting blade. To perform a cutting operation, the instrument extends the cutting blade from a first position to a second position, retracts the cutting blade from the second position to a third position between the first and second positions, and further retracts the cutting blade to the first position. While the cutting blade is not in use, the cutting blade is maintained in the first position using a restraining mechanism in the drive unit, force or torque applied by a motor or other active actuator to the drive unit, or both.
