摘要：
A trocar assembly includes a cannula having a proximal portion and an opposing distal portion. The distal portion is configured to extend into a patient body. The cannula defines an access channel between the proximal portion and the distal portion, wherein the access channel is configured to receive a scope such that the scope can be maneuvered through the access channel to a location within the patient body. A cleaning element at the distal portion is configured to contact at least a distal end of the scope.
