The LITHOCLAST Trilogy by EMS uses ultrasonic energy to fragment stones. It offers a unique combination of ultrasound and ballistic energy delivered through a single probe. This allows for both powerful fragmentation of hard stones and precise dusting of softer ones. Pros: - Effective on various stone types due to combined energy. - Single probe design simplifies procedures. - Integrated suction aids in fragment removal. - Relatively less retropulsion of stones.
