Abstract

The present disclosure relates to a housing for a laparoscopic trocar assembly with an integrated scope-cleaning structure. The housing may include a shell forming a wall portion of a chamber and a cleaning element forming at least a portion of an internal surface of the chamber, the cleaning element configured to remove debris from a distal end of a scope upon contact between the cleaning element and the distal end of the scope. The cleaning element may be movable with respect to the shell of the housing in response to an input force upon the shell that moves a portion of the shell and a portion of the cleaning element between a default state and a displaced state.
