1. A disposable sheath device to be used in conjunction with an endoscope comprised of a body having an insertion tube with optics at a distal end, the disposable sheath device comprising:
a primary lumen having a proximal end and a distal end for covering and protecting the insertion tube from bodily contamination; a connector attached to the proximal end of the primary lumen, the connector being structured and arranged for connecting the disposable sheath device to the body of the endoscope, the connector being adapted to extend longitudinally between the disposable sheath device and the body of the endoscope to accommodate different length insertion tubes; and a second lumen having a radius to accommodate a desired tool and being attached exteriorly to a length of the primary lumen, the second lumen having an insert comparing a tubular body with a longitudinal slit formed therein extending a length of the insert, wherein the slit extends parallel to a longitudinal axis of the secondary lumen to permit radial expansion to accommodate devices having a radius larger than the radius of the second lumen, the tubular body of the insert being substantially commensurate in length to a length of the second lumen, wherein the connector comprises a spring for longitudinal expansion to accommodate an endoscope having an insertion tube that is longer than can be accommodated when the spring is compressed. |
