The authors report the use of a colored microcamera; one of these used in eletronic systems of safety, mounted on a stem with vertical, horizontal and obliques movements, inside a wooden box covered witer fórmica, fed by a stabilized source of 12 volts. Another source of ajusted feeding of 12 volts, suplies energy to a blower, which is responsible for the cooling of the system. The intensity of light of two lamps dicroic of 50 watts each is regulated by a dimmer. In that way, the obtained images become similar to the one from the original equipments of videoendoscopy surgery, helping the beginners to acquire necessary motor coordination to the domain of the technique, with real simulation, superior to the that obtained with "black boxes" with mirrors and static cameras. Courses of videoendoscopy surgery have in electronic simulator an important training instrument and surgical demonstration.
