Trocar assembly with a cleaning element for use during a laparoscopic procedure

A housing for a laparoscopic trocar assembly with an integrated scope-cleaning structure, the housing comprising:

• an outer shell with a proximal entry opening through a proximal wall, a distal exit opening to a cannula that extends distally from a distal wall of the outer shell, and a generally cylindrical wall therebetween, the generally cylindrical wall circumferentially defining a chamber at least partially proximal the cannula and being deformable;
• and
• an inner surface of the generally cylindrical wall comprising at least one cleaning element with a cleaning surface within the chamber, the cleaning surface configured to contact and to remove debris from at least a viewing element of a scope when the generally cylindrical wall is deformed and the at least a viewing element is within the chamber.
