Abstract

The invention pertains to techniques or processes for managing surgical smoke. In one embodiment 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.

Claims

1. A suction apparatus for use with a surgical instrument that may generate 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;

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;

an extendable suction tube having proximal and distal ends; and

an attachment housing fluidly coupled with the ring manifold and with the proximal end of the extendable suction tube.

2. A suction apparatus as recited in claim 1 further comprising and an isolation member disposed within the attachment housing for isolating the extendable suction tube and ring manifold from fluid intercommunication within the attachment housing.

3. A suction apparatus as recited in claim 1 wherein the extendable suction tube is adapted for evacuating liquid or debris during surgical operations with the surgical instrument.

4. 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 ring manifold is adapted to releasably receive at least one of the electrosurgical device, the laser surgical device and the radiosurgical device.

5. A suction apparatus as recited in claim 1, wherein the surgical instrument comprises an electrosurgical pencil having an electrocautery blade, and the suction apparatus further comprises a suction tube lumen of the extendable suction tube arranged for receiving the electrocautery blade of the electrosurgical pencil.

6. A suction apparatus as recited in claim 5 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 blade.

7. A suction apparatus as recited in claim 5 wherein the ring manifold is arranged proximate to the electrocautery blade when the electrocautery blade is received by the suction tube lumen of the extendable suction tube.

8. A suction apparatus as recited in claim 1 further comprising an engagement member for releaseably securing the suction apparatus to the surgical instrument.

9. A suction apparatus as recited in claim 1 wherein the suction apparatus is disposable.

10. A suction apparatus for an electrosurgical pencil having an electrocautery blade 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 may be generated by the electrosurgical pencil;

an extendable suction tube having proximal and distal ends.

11. A suction apparatus as recited in claim 10 further comprising an attachment housing fluidly coupled with the ring manifold and with the proximal end of the extendable suction tube.

12. A suction apparatus as recited in claim 10 further comprising an isolation member coupled with the extendable suction tube and the ring manifold for substantially isolating the extendable suction tube and smoke intake manifold from fluid intercommunication.

13. A suction apparatus as recited in claim 10 further comprises a suction tube lumen of the extendable suction tube arranged for receiving the electrocautery blade of the electrosurgical pencil.

14. A suction apparatus as recited in claim 10 further comprises a thumb control coupled with the extendable suction tube for controlling extendable movement of the distal end of the extendable suction tube over the electrocautery blade.

15. A suction apparatus as recited in claim 10 further comprising an engagement member for releaseably securing the suction apparatus to the surgical instrument.

16. A suction apparatus as recited in claim 10 wherein the suction apparatus is disposable.

17. A method for using a surgical instrument that may generate smoke comprising:

providing a suction apparatus comprising an extendable suction tube and 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;

activating the surgical instrument so as to generate smoke;

evacuating the smoke using suction intake ports of a smoke intake manifold; and

evacuating liquid or debris using the extendable suction tube during surgical operations with the surgical instrument.

18. A method as recited in claim 17 further comprising moveably extending the extendable suction tube.
