A system is provided for controlling the stopping position of a surgical cutting tool relative to a tissue entrance location of a cannula housing the cutting tool. A signal processor is responsive to a motor activation signal to provide a motor activation signal to a motor control unit for driving a motor, which activates the cutting tool positioned in a cannula. The signal processor is responsive to a motor stop signal and to a stop position signal to stop the cutting tool relative to the tissue entrance location of the cannula to thereby avoid trapping a portion of the tissue base between the cutting tool and a boundary of the cannula opening.
