Abstract

An instrument configured for performing a surgery includes a distal end portion, a proximal end portion, and a tube connecting the distal end portion and the proximal end portion. A fluid fitting includes an inlet configured for receiving flow of an irrigating fluid into the instrument and at least two exits configured for guiding the flow of the irrigating fluid out of the instrument. A first exit is configured to allow the irrigating fluid to flow towards the distal end portion of the instrument and a second exit is configured to allow the irrigating fluid to flow towards the proximal end portion of the tube. A size of the first exit is larger than a size of the second exit to enable greater flow towards the distal end portion.
