Abstract
Un instrumento electroquirurgico inalámbrico tiene una pieza manual (10), y un electrodo de tratamiento individual (12) que se proyecta desde un extremo de la pieza manual (10). Contenidos dentro de la pieza manual (10) están un generador de radiofrecuencia, una batería y una proteccion eléctricamente conductora que circunda el generador pero está aislada del mismo. Las corrientes de retorno de radiofrecuencia entre el generador y el paciente fluyen en virtud del acoplamiento capacitivo entre el circuito generador y el paciente, principalmente por medio de la proteccion y el cirujano que sostiene el instrumento.
