Cannula with smoke evacuation housing

A surgical access device comprising:

• a cannula having a cannula housing and a tubular member extending therefrom;
• and
• a seal housing including:
• a base attachable to the cannula,
• an instrument seal,
• a cover having a lower cover portion and an upper cover portion, the lower cover portion attached to the base and the upper cover portion connectable with the lower cover portion, the upper cover portion having a wall depending therefrom and defining a chamber, the chamber including projections depending from the upper cover portion, the projections spaced apart and defining windows therebetween,
• a port extending radially from the upper cover portion, and
• a passage defined between a surface of the wall and the projections, the projections, the windows, and the passage defining a geometry of the chamber that is configured to direct a fluid in the seal housing towards the port, the port being connectable to a source of vacuum.

A method of removing fluid from a surgical access device comprising:

• connecting a source of vacuum to a surgical access device, the surgical access device including:
• a cannula with a cannula housing and a tubular member extending therefrom;
• and
• a seal housing coupled to the cannula housing, the seal housing including:
• a base,
• an instrument seal, and
• a cover having a port extending therefrom, the cover having a lower cover portion attached to the cannula housing and an upper cover portion, the upper cover portion having a chamber therein, the chamber including projections wherein adjacent projections are spaced apart defining windows therebetween, the windows and the projections defining a geometry of the chamber;
• and
• applying a vacuum to the chamber via the port, the vacuum and the geometry of the chamber creating a flow path in the seal housing, the flow path directing a fluid in the seal housing towards the port.
