Electrocautery, also known as heat cautery, refers to the process by which AC or DC currents are passed through a metal wire electrode resistance, to produce heat. The heated electrode is then applied to living tissue to achieve hemostasis or various levels of minor surgical procedures in dermatology, ophthalmology, ENT, plastic surgery, and urology. This Circumcision Tool works by flowing a high current into the filament heater, then the filament heater produces heat which is then used for circumference and dermatology processes. This tool uses a power supply as a voltage source and is equipped with a switch where the Switch functions as a safety control logic switch 0 and 1 heating distributor to the filament heater (nickel). This tool is designed there is a selection of heat intensity so that for cutting small or thin objects can be adjusted the intensity of the heat.
