Abstract

A suction apparatus evacuates the surgical smoke. For example, the suction apparatus may be arranged adjacent to an electrocautery electrode, which may generate smoke during operation, for evacuating smoke from a surgical site. The suction apparatus may have a ring manifold having an inner perimeter for receiving the surgical instrument. A plurality of suction intake ports may be arranged about the outer perimeter of the ring manifold for evacuating smoke that may be generated by the surgical instrument.

Claims

1. A suction apparatus for use with a surgical instrument that generates smoke comprising:

a ring manifold having a lumen extending substantially around the ring manifold, the ring manifold having an inner perimeter adapted to releasably receive a 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 generated by the surgical instrument.

2. A suction apparatus as recited in claim 1

wherein a plurality of suction control ports penetrate the rotatable suction control band, each of the plurality of suction control ports being arranged adjacent to a respective one of the plurality of suction intake ports for variable alignment therewith, so as to provide variably controlled suction for said evacuating of said smoke that is generated by the surgical instrument.

3. A suction apparatus as recited in claim 1, wherein:

the surgical instrument comprises at least one of an electrosurgical device, a laser surgical device and a radiosurgical device; and

the inner perimeter of the ring manifold is adapted for releasably receiving at least one of the electrosurgical device, the laser surgical device and the radiosurgical device.

4. A suction apparatus as recited in claim 1, wherein the surgical instrument comprises an electrosurgical pencil having an electrocautery electrode, and the suction apparatus further comprises:

an extendable suction tube having a proximal end and a distal end;

a lumen of the extendable suction tube arranged for receiving the electrocautery electrode of the electrosurgical pencil; and

an attachment housing supportively coupled with the proximal end of the extendable suction tube.

5. A suction apparatus as recited in claim 4 further comprising a thumb control slideably coupled with the attachment housing and coupled with the extendable suction tube for controlling extendable movement of the distal end of the extendable suction tube over the electrocautery electrode.

6. A suction apparatus as recited in claim 4 further comprising an engagement member for releasably securing the suction apparatus to the electrosurgical pencil.

7. A suction apparatus as recited in claim 4 wherein the suction apparatus is disposable.

8. A suction apparatus as recited in claim 4 wherein the ring manifold is arranged proximate to the electrocautery electrode when the electrocautery electrode is received by the lumen of the extendable suction tube.

9. A suction apparatus as recited in claim 1 wherein:

the surgical instrument comprises an electrosurgical pencil having an electrocautery electrode; and

,

the ring manifold is arranged proximate to the electrocautery electrode when the electrosurgical pencil is releasably received within the inner perimeter of the ring manifold.

10. A suction attachment for an electrosurgical pencil having an electrocautery electrode, the suction attachment comprising:

a ring manifold having a lumen extending substantially around the ring manifold, the lumen for conducting smoke evacuated by the ring manifold, the ring manifold having an inner perimeter adapted to releasably receive the electrosurgical pencil;

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

an attachment housing supportively coupled with the ring manifold; and

an engagement member for releasably securing the suction attachment to the electrosurgical pencil.

11. A suction attachment as recited in claim 10 wherein

a plurality of suction control ports penetrate the rotatable suction control band, each of the plurality of suction control ports being arranged adjacent to a respective one of the plurality of suction intake ports for variable alignment therewith, so as to provide variably controlled suction for said evacuating of said smoke that is generated by the surgical instrument.

12. A suction attachment as recited in claim 10 wherein the suction attachment is disposable.

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

receiving a surgical instrument within a releasable suction apparatus, the releasable suction apparatus having an inner perimeter of a ring manifold, the ring manifold having a lumen extending substantially around the ring manifold, having the inner perimeter of the ring manifold adapted to releasably receive the surgical instrument, the releasable suction apparatus including a rotatable suction control band substantially encircling a plurality of suction intake ports arranged about an 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 generated by the surgical instrument;

releasably securing the releasable suction apparatus to the surgical instrument;

activating the surgical instrument so as to generate smoke; and

evacuating the smoke using the plurality of suction intake ports of the ring manifold.

14. A method as recited in claim 13 further comprising separating the releasable suction apparatus from the electrosurgical pencil.

15. A method as recited in claim 13 wherein the releasable suction apparatus is disposable and the method further comprising disposing of the releasable suction apparatus.
