Abstract: An electrosurgical apparatus performs a cut or incision on epithelial tissue of the body of a human or animal patient. The apparatus includes a generator system configured to generate a radio-frequency electric signal, and a hand piece held by an operator and having an end provided with a single active electrode electrically connected to the generator system. The electric signal generates a cut or an incision when the active electrode comes into contact with epithelial tissue of the body. The electric signal has a power ranging from 0.5 W-20 W and a frequency ranging from 40 kHz-90 kHz. The energy emitted by the signal is transferred from the active electrode to the tissue of the body through capacitive coupling. The tissue is cut at a peripheral temperature ranging from 45° C.-60° C. The electric circuit is closed to ground through a capacitive effect, as the apparatus does not use a return plate.

Abstract: An electrosurgical apparatus includes a generator system configured to generate a radio-frequency electric signal, and a handpiece to be gripped by an operator and having an end fitted with an active electrode electrically connected to the generator system. The signal is capable of polarizing the active electrode so as to generate a glow plasma discharge in the atmosphere when the active electrode is in the proximity of the tissue mass, without propagation of electric current through the patient's body (B).
