Percutaneous access devices are provided with cleaning elements for in situ cleaning of viewing scope lenses during surgical procedures. The access devices will comprise a cannula having an access lumen therethrough. The cleaning element will be disposed at or near the distal end of the cannula, preferably over or across a distal port of the cannula. The cleaning element may comprise an elastomeric membrane, an open cell foam pad, one or more articulated plates, or a combination thereof. Cleaning of the lens of the viewing scope is effected by moving the lens between positions proximal of and distal to the cleaning element.
