Temperature Fields and Lesion Sizes in Electrosurgery and Induction Thermocoagulation

  • Avraham Shitzer


Several ingenious methods are currently used for tissue removal and destruction, including techniques based on mechanical, chemical, and physical principles. The usual mechanical method involves a cutting knife—the “scalpel.” The chemical method is based on the introduction of suitable chemical agents, systemically or locally, to achieve the desired effect. An example is thrombolysis by streptokinase infusion. The physical method, on the other hand, entails a variety of techniques, such as nonionizing radiation, ultrasonic waves, laser beam irradiation, cryosurgery, and electrosurgery. The choice of the method to be applied depends on the nature of the problem and the experience of the surgeon. The end effector of these techniques is the same: the input or removal of heat. This chapter focuses on the use of tissue heating due to electricity and radiofrequency radiation as a lesion-producing agent. Following a physical description of pertinent methods of tissue heating, the production of lesions in tissue by these methods will be quantified by the bioheat transfer analysis.
