Electrosurgical apparatus for the treatment, even without contact, of inner and/or outer tissues

An electrosurgical apparatus comprising:

• a handpiece adapted to be grasped by an operator and comprising an end fitted with an active electrode;
• a generator system operatively and electrically connected to said handpiece, configured to generate a radio frequency electrical signal adapted to bias said active electrode so as to generate a plasma glow discharge between said active electrode and said tissue when said active electrode is in the proximity of said tissue;
• and
• a stabilizing cable, operatively and electrically connected to said generator system, configured to create a circuit with said handpiece and said plasma glow discharge, to allow the recovery from said tissue of a residual surface energy, which has not been grounded through the capacitive coupling alone between a living being and the surrounding environment, through a current return from the tissue towards the generator system,
• wherein the recovery of the residual surface energy from the tissue is achieved by a combination of a first contribution and a second contribution, the first contribution including a return of current from said tissue towards the generator system through the stabilizing cable and the second contribution including a return of the current grounded by the capacitive coupling between the living being and the surrounding environment towards the generator system through a decoupling capacitor.
