Abstract

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.

Claims

1. A trocar assembly with an integrated scope-cleaning structure, the trocar assembly comprising:

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; and

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 to at least a second setting,

wherein in the first setting, a first portion of the cleaning element is in a first location and provides 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, and

wherein in a second setting, the first portion of the cleaning element is displaced to a second location and the scope can extend longitudinally through the distal opening of the housing.

2. The trocar assembly of claim 1, wherein in the second setting, an opening of the cleaning element is aligned with the distal opening of the housing.

3. The trocar assembly of claim 1, wherein the cleaning element includes a rotatable wheel comprising the first cleaning surface and an opening through the cleaning element.

4. The trocar assembly of claim 1, wherein the cleaning element is further movable with respect to the housing to a third setting,

wherein in the third setting, a second portion of the cleaning element forms a second cleaning surface within the housing, the second cleaning surface configured to remove debris from a distal end of the scope.

5. The trocar assembly of claim 1, further comprising a divider separating the housing into a proximal portion of a chamber and a distal portion of the chamber, the divider including an opening aligned with the proximal opening of the housing and the distal opening of the housing, and aligned with an opening of the cleaning element in the second setting.

6. The trocar assembly claim 5, wherein the divider comprises a second cleaning element located in the proximal portion of the chamber and configured for cleaning contact with a distal-facing surface of the scope.

7. A trocar assembly with an integrated scope-cleaning structure, the trocar assembly comprising:

a housing including a proximal opening longitudinally aligned with a distal opening, which distal opening is in fluid and mechanical communication with a trocar cannula; and

a rotatable wheel including a first cleaning surface and a wheel opening, each alignable between the proximal opening and distal opening,

wherein in a first setting, the first cleaning surface is in a first location such that it is longitudinally aligned with the proximal and distal openings of the housing, and

wherein in a second setting, the first cleaning surface is displaced with respect to the first location.

8. The trocar assembly of claim 7, wherein in the second setting, the wheel opening of the rotatable wheel is longitudinally aligned with the proximal and distal openings of the housing such that a distal end of a scope can pass distally longitudinally through the opening of the rotatable wheel and the distal opening of the housing.

9. The trocar assembly of claim 7,

wherein the rotatable wheel further includes a second cleaning surface, also alignable between the proximal opening and distal opening, and

wherein in a third setting, the second cleaning surface is longitudinally aligned with the proximal and distal openings of the housing.

10. The trocar assembly of claim 7, wherein the wheel opening of the rotatable wheel includes a diameter, and wherein a second wheel opening of the rotatable wheel includes a different second diameter.

11. The trocar assembly of claim 7, wherein the housing includes a chamber, and wherein a cleaning element forms another cleaning surface at least partially within the chamber, where the cleaning element includes an opening longitudinally aligned between the proximal and distal openings of the housing.

12. The trocar assembly of claim 11, wherein the another cleaning surface includes a curved proximal-facing surface.

13. The trocar assembly of claim 12, wherein the another cleaning surface includes at least one cleaning property different from the first cleaning surface.
