Microwave Surgical Units

Definition : Devices designed to perform surgery using a microwave frequency (typically 2.45 GHz) energy; the heating effect that causes tissue coagulation is provided by tissue resistance to the high-frequency radiation. These units include a microwave generator and appropriate applicators. The microwave energy delivered by the microwave surgical units is not effective to cut tissues, because they depend on mechanical action for cutting (e.g., scalpel). Microwave surgical units are used in open surgery of highly vascularized organs, such as the spleen and the liver because the thick eschars produced by the relatively deep penetration of microwave fields is very effective in stopping hemorrhage.
