Abstract

In surgery using monopolar HF, there is a constant risk of patients suffering burns at the neutral electrode. Said problem stems from the fact that numerous methods have been devised by which relatively high HF currents are applied for extended periods of time. The present invention solves said problem by providing a neutral electrode, device that is to be used for applying an HF current to a biological tissue. Said improved neutral electrode device comprises at least one latent heat accumulator for absorbing heat. Thus heat peaks can be at least temporarily accumulated until the accumulated thermal energy can be safely released.
