Claims9
A slip ring assembly for use with a surgical shaft assembly, wherein the slip ring assembly comprises:
- a proximal housing portion comprising a proximal connector, wherein the proximal connector comprises a proximal conductor assembly;
- and
- a distal housing portion rotatable relative to the proximal housing portion, wherein the distal housing portion comprises a distal connector comprising a plurality of resiliently biased lever arms operably engaged with the proximal conductor assembly, wherein the plurality of resiliently biased lever arms comprises:
- a first resiliently biased lever arm;
- and
- a second resiliently biased lever arm radially and laterally spaced from the first resiliently biased lever arm;
- wherein the first resiliently biased lever arm and the second resiliently biased lever arm comprise a coating configured to prevent fluid from bridging a connection therebetween.
