“…The use of electrosurgery requires an understanding of human body tissues and appropriate power and mode settings to avoid the effects of damage to body tissues [1]. According to research, the most basic things that make electrosurgery dangerous is one of them due to lack of understanding of the technology because the monopolar current generated is greater and will spread more widely throughout the body than by bipolar therefore, the correct power and mode settings are needed for reducing the risk of injury [2][3][4] [5]. The heat generated by electrosurgery can also have an impact on the network if the tissue implant is very sensitive to heat because even a little current and voltage passing through the network can damage the network.…”

Electrosurgery Unit is some machine to human body surgery. Electrosurgery Unit is uses a high frequency to human body tissue surgery, that causes blood who came out can be dicrease during surgery. When using a conventional scalpel is something that is highly avoided because it will cause contraindications to lack of blood which will be very dangerous for the patient. The purpose of this study is to design a tool that is used to replace a conventional scalpel with a tool that utilizes high frequency (400 KHz) generated by the oscillator circuit. In this study. The researches used Monopolar method and used two modes Cutting and Coagulation in order to eliminate faradic effects on body tissues causes high frequency, there is the high frequency will be adjusted to the duty cycle which aims to obtain various types of surgery required by doctor which is cutting 100% on and coagulation 6% on 94% off where is set it with arduino program. In this study, the researchers took advantage of the type of heat effect produced by high frequencies which were concentrated at one point so that it could be used to carry out the process of surgery on body tissues so as to minimize the occurrence of large blood loss. The result of this study is will be centered at one point on an object there is show up the depth difference of the cutting mode and the wide large difference of the coagulation mode. The module design resulted the power lowest at 300Ohm ESU Analyzer setting is 30Watt and the highest at 300Ohm setting too is 68Watt. The module design resulted the power lowest at 300Ohm ESU Analyzer setting is 30Watt and the highest at 300Ohm setting too is 68Watt at mode Cutting and the highest and lowest Coagulation mode using impedance setting the same there is 300 Ohm is constant 3Watt power result’s. The weaknesses at this research is the power still lower then the Electrosurgery Unit where is in the hospital. It can be fix for the next research using increase the final amplifier and maybe increase the frequency where is gonna make the voltage of the final amplifier be much better then this research

“…At this frequency, electrosurgical energy can pass through the patient with minimal neuromuscular stimulation and there is no risk of electric shock (Benias & Carr-Locke, 2019). Electrosurgery frequency limit is 300 KHz -5 MHz (Knopf et al, 2013), (Dafinescu et al, 2012), (Karaki et al, 2017). As seen in Figure 1.…”

Electrosurgery unit has the purpose of damaging certain body tissues by heating the tissue. In this study there are several modes and also power selection. The contribution of this research is to design the power management and also the addition of several modes for the surgical process. Electrosurgery Unit involves the use of IC CMOS 4069 as a frequency generator. The frequency output is set at 250 KHz and then passed on to the pulse regulator circuit and controlled by using Arduino and then forwarded to the inverter circuit which functions to increase the voltage and output in the form of power. Modules are calibrated using ESU Analyzer. This module is equipped with a selection of LOW, MEDIUM, and HIGH power. And also there are some additional modes including Blend 1 and Blend 2. After the measurement is carried out, the voltage values obtained at the setting of low, medium high, on the inverter input with a value on Blend 1 mode low 80 V with an error of 0.84%, Medium 90 V with error 0.84%, High 104 V with an error of 0.81%, in Blend 2 mode low 84 V with an error of 0.83%, Medium 86 V with a error of 0.85%, High 105 V with an error of 0.81%, the Cutting mode is low 162 V with an error of 2.88%, medium 172 V with an error of 3.03%, High 192 V with an error of 2.86%. The measurement shows an error of less than 1% for Blend 1 and Blend 2 modes while cutting is less than 3%. The results of this study can be implemented in order to minimize errors due to lack of power settings and mode selection during surgery.
