The present invention provides a surgical footswitch that includes a base, a pedal, an encoder assembly, a wireless interface, and an internal power generator. The pedal mounts upon the base and pivots. The encoder assembly couples to the pedal. As the pedal pivots, the encoder assembly translates the mechanical signal of the pedal into a control signal based on the pedals position and/or orientation. The wireless interface couples the encoder assembly to receive the control signal. The wireless interface also couples the surgical footswitch to a surgical console operable to control and direct surgical equipment. 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 theater. 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.

The surgical footswitch of claim 2, wherein the surgical console directs the surgical equipment to a predetermined state when wireless communications between the surgical footswitch and surgical console are interrupted. 7. The surgical footswitch of claim 2, further comprising a ready indicator, wherein the ready indicator provides a ready indication when the stored energy exceeds a predetermined level. 8. The surgical footswitch of claim 7, wherein the surgical console only accepts the control signal when the stored energy exceeds a predetermined level. 9. The surgical footswitch of claim 1, further comprising a motion detector assembly operable to be worn by a user and to transmit motion information to the surgical footswitch, wherein the encoder assembly is operable to produce an additional control signal based on the received motion information. 10. The surgical footswitch of claim 1, further comprising a motion detector assembly operable to be worn by a user and to transmit motion information to the surgical console via the surgical footswitch, wherein the surgical console is operable to produce an additional control signal based on the received motion information. 11. A surgical footswitch, comprising: a base; a pedal mounted to the base; an encoder assembly coupled to the pedal, wherein the encoder assembly is operable to produce a control signal based on the pedal's position and/or orientation; a motion detector assembly operable to be worn by a user and to transmit motion information to the surgical footswitch, wherein an additional control signal may be generated based on the received motion information; and a wireless interface communicatively coupled to the encoder assembly and motion detector, wherein the wireless interface is operable to communicatively couple the surgical footswitch to a surgical console, and wherein the surgical console is operable to receive the control signals and control a surgical equipment based on the control signals. 12. The surgical footswitch of claim 11, wherein the surgical console is operable to produce the additional control signal based on the received motion information. 13. The surgical footswitch of claim 11, wherein the motion detector receives at least one radio frequency (RF) signals from at least one transmitter located at a predetermined location. 14. The surgical footswitch of claim 13, wherein the at least one transmitter is coupled to the surgical console. 15. The surgical footswitch of claim 11, wherein motion detector further comprises acceleration sensors operable to produce motion information. 16. The surgical footswitch of claim 11, wherein outputs of the acceleration sensors may be integrated over time to produce motion information. 17.
