1. A transperineal stepper, comprising:
an acoustic probe including a first end which is insertable into a patient;
a probe mounting structure which holds the acoustic probe;
a base; and
a gearless longitudinal translation device connected to, and enabling longitudinal movement of, the probe mounting structure and the acoustic probe with respect to the base, wherein the gearless longitudinal translation device comprises:
a first friction wheel having at least a first beveled side surface, and a second friction wheel having at least a second beveled surface; and
a first linear rod disposed between the first and second friction wheels and in contact with the first and second beveled surfaces,
wherein a displacement of the first linear rod longitudinally with respect to the first and second friction wheels causes the acoustic probe and the probe mounting structure to be longitudinally displaced with respect to the base.
