SURTRON® ABC is an Argon module that can be connected with a compatible electrosurgical unit (SURTRON HP) SURTRON® ABC is a module that can be connected with a compatible electrosurgical unit (SURTRON HP) and, compatible applicators and probes, specific for coagulation electrosurgical procedures with Argon gas, indicated for both open surgery, flexible endoscopy and bronchoscopy. Argon is an inert gas that used in combination with specific currents for high frequency coagulation generated by an electrosurgical unit, allows to obtain a superficial coagulation without contact thanks to the ionization of the gas flow through the high-frequency current. SURTRON® ABC is realized so that the connection to an electrosurgical unit with compatible characteristics to the Argon procedures, allows the erogation both through a manual activation and foot activation. The connection to the ABC unit doesn?t preclude the use of other functions of the electrosurgical units, in fact, in case of use of the compatible LED units, the erogation of the Argon gas occurs only in case of erogation of current of high-frequency coagulation (SPRAY).
