CLAIMS

1. A slip ring assembly for use with a surgical shaft assembly, the slip ring assembly comprising:

a first connector;

a first conductor mounted on the first connector;

a second connector rotatable relative to the first connector;

a second conductor mounted on the second connector, wherein the second conductor is in contact with the first conductor; and

an interface between the first connector and the second connector, wherein the interface is configured to trap water away from at least one of the first conductor and the second conductor.

2. The slip ring assembly of Claim 1 , wherein the interface comprises a body portion that includes an opening configured to receive the second conductor.

3. The slip ring assembly of Claim 1 , wherein the interface comprises ribs protruding from the body portion.

4. The slip ring assembly of Claim 3, wherein the ribs are concentric.

5. The slip ring assembly of Claim 1 , wherein the interface is flexible.

6. The slip ring assembly of Claim 1 , wherein the interface is comprised of an elastomeric material.

7. The slip ring assembly of Claim 1 , wherein the interface is fixed to the second connector.

8. The slip ring assembly of Claim 7, wherein the interface is rotatable with the second connector relative to the first connector.

9. A surgical shaft assembly, comprising:

a proximal shaft portion, comprising:

a proximal connector supported in the proximal shaft portion; and

first conductors mounted on the proximal connector; and

a distal shaft portion rotatable relative to the proximal shaft portion, wherein the distal shaft portion comprises:

a distal connector supported in the distal shaft portion;

second conductors mounted on the distal connector, wherein the second conductors are spaced apart laterally and radially from one another; and

a gasket disposed between the proximal connector and the distal connector, wherein the gasket is configured to resist water flow toward at least one of the first conductors and the second conductors.

10. The surgical shaft assembly of Claim 9, wherein the gasket comprises openings configured to receive the second conductors.

1 1 . The surgical shaft assembly of Claim 10, wherein the gasket comprises tread elements protruding therefrom.

12. The surgical shaft assembly of Claim 1 1 , wherein the tread elements are concentric.

13. The surgical shaft assembly of Claim 9, wherein the gasket is flexible.

14. The surgical shaft assembly of Claim 9, wherein the gasket is comprised of an elastomeric material.

15. The surgical shaft assembly of Claim 9, wherein the gasket is fixed to the distal connector.

16. The surgical shaft assembly of Claim 15, wherein the gasket is rotatable with the distal connector relative to the proximal connector.

17. A slip ring assembly for use with a surgical shaft assembly, the slip ring assembly comprising:

a slip ring;

a first conductor mounted on the slip ring;

a commutator rotatable relative to the slip ring;

a second conductor mounted on the commutator; and

a flexible member disposed between the slip ring and the commutator, wherein the flexible member comprises:

a body portion; and

flexible portions extending from the body, wherein the flexible protrusions are elastically deformed against the slip ring.

18. The slip ring assembly of Claim 17, wherein the body portion comprises an opening configured to receive the second conductor.

19. The slip ring assembly of Claim 17, wherein the flexible member is fixed to the commutator.

20. The slip ring assembly of Claim 19, wherein the flexible member is rotatable with the commutator relative to the slip ring.
