Abstract
A method of defogging and cleaning a laparoscope includes: (1) inserting a laparoscope into a sheath; (2) inserting the laparoscope and sheath into a body cavity; (3) providing gas to a plurality of gas lumens within a wall of the sheath such that the gas flows through the gas lumens and over a lens of the laparoscope to defog the lens while the laparoscope is in the body cavity; and (4) providing a fluid comprising a surface-active agent to a fluid lumen within the wall of the sheath such that the fluid flows through the fluid lumen and over the lens to clean the lens while the laparoscope is in the body cavity.
