PROBLEM TO BE SOLVED: To provide a calculus crushing probe that can effectively crush even a large calculus. SOLUTION: By providing an insertion hole 10 in an ultrasonic calculus crushing probe 4, making the probe section 11 of a mechanical impact calculus crushing probe 5 insertable, and making a spikelike protrusion protrude and engage with a calculus when the probe section 11 is inserted, the probe can effectively crush a large calculus.
