Methods and devices for maintaining visibility and providing irrigation and/or suction during surgical procedures

A surgical device, comprising:

• an annular sheath having first and second passageways extending therethrough, the first passageway configured to receive a surgical instrument and the second passageway configured to allow fluid to flow therethrough, the second passageway having a plurality of openings positioned proximal to a distal most opening of the second passageway, the plurality of openings being in fluid communication with one another;
• a self-sealing element disposed in the second passageway;
• and
• a fluid conduit configured to move between a first position in which the self-sealing element provides a fluid seal in the second passageway and a second position in which the self-sealing element does not provide a fluid seal in the second passageway, and when the fluid conduit is in the first position, fluid flowing through the second passageway can flow through each of the plurality of openings and be substantially directed toward a distal end of surgical instrument disposed in the first passageway, and when the fluid conduit is in the second position, fluid flowing through the second passageway can flow through the distal most opening of the second passageway and be substantially directed away from a distal end of the sheath and into a body cavity.
