Electrosurgical Unit

ESU is a versatile system meeting all operating theatre requirements. It is equipped with a fast microprocessor, processing all operating parameters in real time. It enables fast automatic current adjustment to changing operating conditions. Electrosurgical units (ESU) use a high-frequency electrical current to cut tissue and control bleeding by causing coagulation. Tissue resistance to the high-density current causes a heating effect which results in tissue destruction. Electrical current is delivered and received through cables and electrodes. The electrodes may be activated by either a handpiece switch or a footswitch. The ESU may use a monopolar or a bipolar mode. Special modes enable operation in difficult conditions, laparoscopy, and endoscopy. These systems include an electrosurgical generator (i.e., power supply, waveform generator) and a hand piece including one or several electrodes.
