It's a probe that uses high power RF energy to cut and cauterise simultaneously. This is the single use sterile pen that connects to a very complex and expensive machine that provides the RF energy at a fairly high voltage. The return path for the current is a flat electrode stuck onto a suitable area of the patient's body. At the frequencies involved there's no electric shock effect. Just heat or burning at the point of contact. Further investigation shows that you can get blade, needle, ball and loop electrodes.
