Diathermy principle
WebFeb 27, 2015 · Physical principles. Radio frequency (RF) surgical diathermy or electrosurgery uses the heat generated by an electric current, 1 often delivered at more than 200 V, passing through a small amount of tissue to cut, destroy or vaporize that tissue and to create haemostasis by causing coagulation and sealing of small blood vessels. Weband low currents ! this is the principle of diathermy e. Surgical diathermy usually uses very high frequencies between 0.5 ~ 1.5 MHz ∴ heating with minimal stimulation of myocardium, muscles and nerves f. Amount of heat generated when current passes through body depends on current density • Current density = current per unit area
