a suction tube lumen of the suction tube arranged to receive the electrocautery electrode.

5. The system of claim 1 , further comprising an electric console for providing power and wired control signals to the surgical device, wherein the wireless footswitch adapter receives the higher power mode wireless signal in response to the pedal signal and transmits a wired signal representative of the higher power mode wireless signal to the electric console.

6. The suction apparatus of claim 5 , further comprising:

an engagement member for releasably securing the suction apparatus to the surgical instrument.

7. A suction apparatus for an electrosurgical pencil having an electrocautery electrode comprising:

a control slideably coupled to an attachment housing to variably seal at least one control port;

a suction tube having proximal and distal ends, the proximal end of the suction tube fluidly coupled to the at least one control port via the attachment housing, the at least one control port configured to also be variably sealed by an operator's finger to variably control suction at the distal end of the suction tube;

a ring manifold with a ring lumen extending substantially around the ring manifold, the ring manifold having an inner perimeter adapted to releasably receive the electrosurgical pencil, the ring manifold having an outer perimeter, and;

a rotatable suction control band substantially encircling a plurality of suction intake ports arranged about the outer perimeter of the ring manifold for variably sealing the plurality of suction intake ports of the ring manifold, so as to variably control suction provided externally to the plurality of suction intake ports for evacuating smoke that is to be generated by the electrosurgical pencil.

8. The suction apparatus of claim 7 , further comprising:

a suction tube lumen of the suction tube configured to receive the electrocautery electrode of the electrosurgical pencil.

9. The suction apparatus of claim 7 , wherein the at least one control port comprises a first control port and a second control port, and the control slideably misaligns the first control port and the second control port to variably seal the at least one control port to control the suction at the distal end of the suction tube.

10. The suction apparatus of claim 9 , further comprising:

at least one movement limiting slot coupled with the attachment housing for limiting movement of the control to a first preselected extent wherein the first and second control ports are arranged in substantial alignment when the control is slideably positioned to the first preselected extent.

11. The suction apparatus of claim 10 , wherein the at least one movement limiting slot is to limit movement of the control to a second preselected extent wherein the first and second control ports are arranged in substantial misalignment when the control is slideably positioned to the second preselected extent.

12. The suction apparatus of claim 11 , wherein the control also determines a position of the distal end of the suction tube relative to the electrode of the electrosurgical pencil.

13. A method for using a surgical instrument that generates smoke, comprising:

providing a surgical instrument received within an inner perimeter of an attachment housing, the attachment housing comprising a suction tube, a ring manifold with a ring lumen extending substantially around the ring manifold, the ring manifold having an inner perimeter adapted to releasably receive the surgical instrument, the ring manifold having an outer perimeter, and a rotatable suction control band substantially encircling a plurality of suction intake ports arranged about the outer perimeter of the ring manifold for variably sealing the plurality of suction intake ports of the ring manifold, so as to variably control suction provided externally to the plurality of suction intake ports for evacuating smoke that is to be generated by the surgical instrument, a fluid output port in fluid communication with the suction tube, and a smoke output port in fluid communication with the smoke intake manifold;

generating smoke by using the surgical instrument;

evacuating the smoke via the suction intake ports;

outputting the smoke via the smoke output port;

evacuating liquid via the suction tube during surgical operations with the surgical instrument;

outputting the liquid via the liquid output port;

controlling an amount of suction provided by the suction tube to evacuate liquid by variably aligning a first control port and a second control port;

controlling the amount of suction provided by the suction tube by sealing the first control port with an operator's finger.

14. The method of claim 13 , wherein the first control port and the second control port are variably aligned by a slide control.
