Abstract
Means for preventing contamination of the surgical viewing instrument including a flexible bag mounted on the proximal end of a hollow double walled tubular elongated member concentrically mounted to a borescope or surgical viewing instrument where the space between the walls define a passage for flowing fluid to a cuff or vortex generator disposed at the distal end of the tubular member which defines a discretely configured discharge port for flowing fluid over a lens surface for cleansing and defogging purposes. The lens serves to prevent blood, body fluid and other contaminates from back flowing and contaminating the surgical viewing instrument. A two-piece locking handle may be used to lock the lens cleaning apparatus to the borescope. Another embodiment includes a flexible tube utilized with the cuff.
