Energy Devices in Surgery – Principles and Specifics of Use

M. Zashev, V. Mitova, R. Gornev


The expansive development of surgery in the past two decades has been accompanied by the establishment and improvement of a number of energy devices. They reduce intraoperative blood loss and lead to better postoperative results. Their proper use allows the surgeon to perform a wide range of procedures safely, efficiently and with a minimal tissue trauma. The main goals are: reduction of intra- and postoperative complications, shortening of the intraoperative time and improvement of the outcome of the surgery. The knowledge of the mechanisms of action, the indications and contra-indications for usage of the specific devices have a main role in achieving these goals.The most commonly used energy devices in surgery are: mono- and bipolar, ultrasonic destructor, Argon plasma coagulation, CUSA, devices for reducing smoke in laparoscopic surgery, and others. Their use without prior training, however, can lead to many negative consequences. Therefore, the surgical team should be encouraged to study the fundamental biophysical effects and the specificity of use of such devices.


Keywords: energy devices, monopolar, bipolar, intraoperative and postoperative complications
