Apparatus and method for electrosurgical suction

摘要

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.

主权项

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.
