A surgical cautery device includes a voltage generator, a controller, forceps, an actuator, and a receiver. The voltage generator is configured to be electrically connected to a power source. The forceps are electrically coupled to the voltage generator and configured to cauterize tissue. The actuator is configured to generate and wirelessly transmit an on/off signal. The receiver is operable to wirelessly receive the on/off signal. The controller controls power to the voltage generator from the power source in response to the on/off signal.
