Abstract

The present disclosure relates to a trocar assembly with an integrated scope-cleaning structure. The trocar assembly may include a chamber with a proximal opening configured to receive a distal end of a scope. A cannula extend distally from the chamber and may be configured to extend distally into a patient body. The cannula may be further configured to receive the distal end of the scope such that the scope can be maneuvered through the cannula to a location within the patient body. The trocar assembly may include a cleaning element forming a surface within the chamber, where the surface of the cleaning element is configured to remove debris from at least one non-longitudinal, end-facing surface of the scope.
