The handpiece extends in a substantially axial direction. A coupler is included having a cylinder portion and a supply-end portion, the cylinder portion being assembled into the handpiece extending in the axial direction toward the distal end. The cylinder portion includes at least one seal that interfaces with an interior of the body so as to isolate a portion of the body interior into at least one distinct chamber. The supply-end portion of the coupler extends from the proximal end of the handpiece body at an angle from the axis. The supply-end portion also includes a plurality of outlets, the at least one distinct chamber in fluid communication with one of the outlets of the plurality of outlets.
