Trocar assembly with a cleaning element for use during a laparoscopic procedure
First Claim
1. A housing for a laparoscopic trocar assembly with an integrated scope-cleaning structure, the housing comprising:
- a shell forming a wall portion of a chamber; and
a cleaning element that is located proximal a cannula with the cannula extending distally away from the chamber, the 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,wherein the cleaning element is 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.

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.

10. 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. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A method for cleaning a scope, the method comprising:
-
maneuvering a distal end of the scope proximally out of a cannula to a location within a chamber of a trocar assembly, the chamber at least partially formed by a shell wherein a cleaning element comprises a surface within the chamber; moving the cleaning element from a default state to a displaced state by displacing an external-facing surface of the chamber inwardly; and removing debris from at least a distal-facing surface of the scope moving the scope and in contact with a cleaning element. - View Dependent Claims (19, 20)
