Electric scalpels are used for cutting of biological tissue, for example, for resection of tumour tissue in surgery. During the electrosurgical procedure a plasma is ignited in a gap between the electric scalpel and the tissue. In this study, the plasma operated on porcine kidney and a tissue substitute (cellulose impregnated with isotonic saline) is characterised by means of voltage‐current measurements, microphotography, optical emission spectroscopy and numerical simulation. The molecular emission of nitrogen is used for the determination of the gas temperature and the reduced electric field. The electron density is determined using the measured electric current density.
