AbstractAn improved disposable sheath for a medical endoscope of the type that includes an elongated bundle of optical fibers for viewing an internal surgical site, the endoscope including a distal tip adapted to transmit images from the surgical site through the fibers. The improved sheath having an elongated housing with proximal and distal ends in which the distal end has top and bottom portions. A first opening extends through the housing for receiving the endoscope and a second opening extends though the housing for transmitting fluid through the housing. The proximal end of the housing is adapted to secure the housing relative to the endoscope and to connect the second opening to a source of fluid. The first opening is unobstructed at the distal end of the housing to allow the distal tip of the endoscope to project past the top portion of the distal end. The bottom portion of the housing distal end extends beyond the distal tip of the endoscope. The second opening of the housing extends through the bottom portion of the housing distal end so that fluid flowing out of the second opening will clean the distal tip of the endoscope.
