Abstract: A method and apparatus for electric surgery includes generating oscillations of high frequency electric energy of substantially constant amplitude, controlling the duration of and spacing in time between each series of oscillations generated and applying the generated energy through an electrode for the purpose of making surgical incisions and coagulating blood at the point of incision. A common generator serves as a source of the electric energy for different surgical procedures, the duration and spacing between each series of oscillations being closely controlled according to their intended application and in such a way as to minimize power requirements and the possible hazards of use either to the doctor or to the patient.
