A harmonic scalpel cuts via vibration. The scalpel surface itself cuts through tissue by vibrating in the range of 55,500 Hz. The high frequency vibration of tissue molecules generates stress and friction in tissue, which generates heat and causes protein denaturation. This technique causes minimal energy … See more The harmonic scalpel is a surgical instrument that (unlike electrosurgery) uses ultrasonic vibrations to cut and cauterize tissue. See more The Harmonic brand is manufactured in Mexico and distributed by Ethicon Endo-Surgery a subsidiary of Johnson & Johnson. See more The harmonic scalpel may be superior to electrosurgery in that it can cut through thicker tissue, creates less toxic surgical smoke, and poses somewhat less of a risk for electrocution or other potentially fatal complications.
