1. A phacoemulsification handpiece comprising:
a proximal portion having a longitudinal axis, and a first end and a second end, wherein an aspiration connector, an irrigation connector, and a power connector couple with the first end;
a distal portion along the longitudinal axis and comprising a coupling configured to couple a needle with the distal portion;
a lever connected with the coupling and extending outwardly from the longitudinal axis through the distal portion;
wherein actuation of the outwardly extending aspect of the lever provides a rotation of the coupling independent of rotation of the distal portion;
wherein a fluidic connection between the irrigation connector and an irrigation sleeve proximate the needle is routed around the coupling.
