Abstract

A trocar assembly with an integrated scope-cleaning structure may have a proximal portion configured for accessibility by a user and a cannula extending distally from the proximal portion and configured to extend distally into a patient body, where the cannula is further configured to receive a distal end of a scope such that the scope can be maneuvered through the cannula to a location within the patient body. A cleaning element may be included, where the proximal portion includes a housing, where the cleaning element is substantially located within the housing.
