A wireless control device for controlling, with a human foot, an apparatus for multiple surgical functions. The device includes a base having small dimensions, at least two modules mounted on the base for generating specific control signals for each of the surgical functions, a transmitter for transmitting the control signals, a receiver receiving the control signals, a source of electricity for supplying the transmitter with electrical current, and two actuators, actuated by the human foot and pivotally mounted to act simultaneously on the corresponding module, the transmitter, and the source of electricity. The actuators are pivotally mounted around respective axes that are perpendicular to each other.
