Peripheral simulation and / or practical endoscopies computer, the type of fixing by suction cups and / or clamps to a horizontal surface, and which have buttons and at least a lever or wheel mechanically coupled to at least a potentiometer which varies the frequency of at least one digital pulse generated by an astable circuit, which preferably connects to the computer through a serial or usb connector; characterized in that it consists of a base where the suction cups are arranged and / or fixing brackets to the horizontal surface, mounting on the base a socket which, in turn, a fitted lever pivotally movably mounted about an axis horizontal, which has springs that hold it in a stable position substantially centered on its route; on top of the handle a head, where various buttons and three concentric independently rotating wheels supported by a common shaft which mounts an end nut regulating friction between them are arranged is coupled; the wheels have peripheral indentations and / or radial extensions for actuation; the rotation of each wheel is limited by stops; both the lever and at least two of the wheels are mechanically and independently engage different peripheral potentiometers.
