An experimental study of a new type electrode for preventing burn injury of skin on percutaneous microwave coagulation therapy

Abstract

As a local treatment of hepatocellular carcinoma, percutaneous microwave coagulation therapy has been increasingly applied. This therapy, however, has some points to be improved and one of them is burn injury of the skin around the inserted electrode. In order to prevent burn injury, we have developed a new type electrode which has smaller temperature elevation on the surface of electrode nearly as half as compared with the former type of electrode without losing coagulation ability.
