  • Abstract
  • Look Inside

Harmonic Scalpel (HS) is a surgical device utilizing ultrasonic energy to cut and coagulate tissues, different from conventional Ultrasonic Cavitational Aspirator (UCA) which is designated to fracture and aspirate soft tissues. In comparison with other energy sources such as electric surgery or laser surgical unit, the system coagulates tissues with relatively low heat and limited lateral thermal injury without charring the tissues. It also generates no smoke and the patient is completely isolated from the electrical circuit. These features of HS are considered very effective not only in endoscopic surgery but also in open surgery.
