Abstract

Electrosurgical Unit(ESU) is medical equipment that cut or coag tissues using electrical energy. It is used in hospitals' outpatient clinic room and operating room. Improper use of an ESU may cause fatal injuries to the patient, such as burns. So, before using an ESU, make sure that it is supplying enough energy for cut and coag by measuring the output power and checking the output power cable. In this study, we developed a simple ESU power measurement system PW100 that allows anyone to check the basic output power. And PW100 can check the state of the cable associated with the output power before using ESU. Then, we compared the measured output power of the PW100 with an ESU Analyzer which was commercialized, and compared the performance. In the experiment, the output power measured by the PW100 was lower value than an ESU Analyzer's that. However, the PW100's output power measured in the 5% error range and showed stable reproducibility by a low %RSD value.
