The invention provides a surgical footswitch (10) that includes a base, a pedal (16), and encoder assembly (22), a wireless interface (24), and an internal power generator (34). The encoder assembly couples to the pedal. As the pedal pivots, the encoder assembly translates the mechanical energy of the pedal into a control signal based on the pedals position and/or orientation. The wireless interface couples to the encoder assembly to produce the control signal. The wireless interface also couples the surgical footswitch to a surgical console (28) operable to control and direct surgical equipment (32). The wireless interface passes the control signal from the encoder to the surgical console, which then directs the surgical equipment based on the control signal. This wireless interface eliminates the tangle of wires or tethers, which may be a hazard in the surgical theatre. The internal power generator translates footswitch movement into stored energy to eliminate potential failures of the footswitch during a procedure and overcome the need to replace batteries within the footswitch. |
