Design of Automatic Power measuring Electrosurgical Unit

Abstract

Even after the introduction of Electrosurgery a hundred years ago, very few electrosurgical units (ESU) were able to measure and regulate the power delivered to the body. Normally surgeries are performed for specific applications based on the output power delivered from ESU to human body.This paper presents the design of an ESU which can automatically measure the power and stops the system once it exceeds the acceptable range of power. This approach will help to reduce the damage caused to the biological tissue since power is monitored continuously. The role of analyser will be decreased to some extent as the device itself can monitor power. Proper regulation of power is required to produce the desired results. The model   is designed and simulated to ensure the working of the circuit. Simulation results show that power is monitored continuously and once it exceeds the acceptable  range,  the  system  will  go  for a complete shutdown thereby indicating variation.The above mentionedactionisperformedwiththehelpofmotor.
