Ethicon® Harmonic Scalpel (Ethicon US, LLC, www.ethicon.com/na) is an ultrasonically activated cutting instrument that converts electrical energy to mechanical energy. The blade vibrates at 55,500 Hz creating heat that coagulates vessels and cuts tissue. Hand pieces are available in various sizes and types for both open surgical procedures and minimally invasive surgery. It is FDA‐approved to seal vessels up to 5 mm diameter and does not create smoke. The tissue is compressed between a Teflon anvil and the vibrating blade. There are two settings, one to seal the tissue and another to cut through the tissue.
