Abstract
Methods and devices are provided for providing irrigation and/or suction to a surgical site and maintaining clear visibility through a lens of a scoping device during a surgical procedure. In general, the methods and devices can allow for a surgical instrument to maintain visibility during a surgical procedure using a fluid conduit coupled to the surgical instrument. A surgical device can include a sheath having at least one lumen extending therethrough configured to allow a surgical viewing instrument to be disposed therein. The sheath can also have a passageway extending therethrough configured to allow fluid to flow therethrough. The fluid conduit can be configured to be movable between positions that can allow alternative directions of fluid toward and/or away from a viewing element on the surgical instrument and fluid away from the viewing element and toward a surgical field in a body cavity.
