The Ethicon Harmonic Generator 300 System utilizes ultrasonic energy to enable hemostatic cutting and/or coagulation of soft tissue. The system consists of an ultrasonic generator, a foot switch, an optional hand switching adaptor, a hand piece, and a variety of open and minimally invasive instruments. Note: Throughout this manual “instrument(s)” refers to The HARMONIC Generator 300 System blades, ball coagulators, or coagulating shears.
All the HARMONIC instruments vibrate longitudinally at 55.5 kilohertz. This ultrasonic vibration at the blade enhances its cutting ability. The same vibration seals small vessels with coagulated blood and tissue proteins. Hemostasis occurs when tissue couples with the instrument. This coupling causes collagen molecules within the tissue to vibrate and become denatured, forming a coagulum.
The Ethicon Harmonic Generator 300 System is indicated for soft tissue incisions when bleeding control and minimal thermal injury are desired. The HARMONIC Generator 300 System instruments can be used as an adjunct to or substitute for electrosurgery, lasers,and steel scalpels.
