Abstract
The disposable endoscope sheath includes a low-profile sleeve member that can accommodate a variety of different endoscope lengths that are longer than the sleeve member. In several embodiments of the invention, the sleeve member includes irrigation channels that do not communicate with an endoscope receiving space. In other embodiments of the invention, irrigation fluid passes through the endoscope receiving space of the sleeve member. In all embodiments of the invention, irrigation fluid that is expelled from the sleeve member can flush surgical debris away from the viewing end of the endoscope. The sleeve member has a generally low profile and does not require continuous suction to halt the expulsion of irrigation fluid from the sheath when the irrigation function is not being used. A brief reverse suction can be used to remove a residual drop of cleaning solution from the viewing end of the sheath.
