The present disclosure relates to a trocar assembly with an integrated scope-cleaning structure. The trocar assembly may include a housing defining boundaries of a chamber with (a) a proximal opening configured to receive a distal end of a scope, and (b) a distal opening in fluid and mechanical communication with a trocar cannula. The trocar assembly may further include a cleaning element located at least partially between the proximal opening and the distal opening, where the cleaning element is movable with respect to the housing from at least a first setting where a first portion of the cleaning element may be in a first location and may form a first cleaning surface within the chamber, the first cleaning surface configured to remove debris from a distal end of the scope when the distal end of the scope contacts the first portion of the cleaning element.
