WebThe Harmonic scalpel is a surgical instrument used to simultaneously cut and cauterize tissue. Unlike Electrosurgery, the harmonic uses ultrasonic vibrations instead of electric … WebNov 15, 2024 · The Harmonic scalpel works by dividing the tissues longitudinally through high-frequency ultrasonic waves, which potentially takes less time for tissue damage than conventional methods. Besides, the Harmonic scalpel produces lower temperature than electrocautery and hence less liability to excessive tissue damage and blood loss.
