Smoke extraction device

A smoke extraction device comprising:

• a body portion defining a first lumen, the body portion being adapted to be connected to a source of vacuum;
• a channel portion connected to the body portion and defining a second lumen in communication with the first lumen, the second lumen having a substantially U-shaped inlet opening;
• and
• an attachment member including a conical member secured adjacent to the channel portion and a resilient clamp secured to the body portion the attachment member being configured and dimensioned to releasably secure the smoke extractor device to a surgical instrument having a distally extending tool member.

A smoke extraction device comprising:

• an elongated body portion defining a first lumen and having first and second ends, the first end being adapted to be connected to a source of vacuum;
• a channel portion connected to the second end of the elongated body portion, the channel portion having an inlet opening which communicates with the first lumen;
• an attachment member operatively secured to the elongated body portion, the attachment member being configured and dimensioned to releasably secure the smoke extractor device to a surgical instrument having a distally extending tool member, wherein the attachment member is positioned such that the inlet opening does not extend above the tool member, the channel portion being located so as to provide unobscured visibility at the surgical site;
• an elongated extension defining a second lumen;
• and
• an adapter having a first end configured to releasably engage the elongated body portion and a second end configured to releasably engage the elongated extension, wherein the first lumen and the second lumen are coaxial.
