ABSTRACT:
A fiber tip fluid output device is provided for holding a fiber tip in an electromagnetic energy cutting apparatus and for directing water particles over a radiation delivery end of the fiber tip. The fiber tip fluid output device includes a generally cylindrical body having an outer surface, a proximal end, a distal end, and a lumen extending between the proximal end and the distal end. The lumen is sized and shaped to accommodate a fiber tip therethrough so that the fiber tip extends through the lumen from the proximal end to the distal end of the generally cylindrical body. The fiber tip fluid output device further includes a plurality of apertures extending around the generally cylindrical body, with each of the apertures of the plurality of apertures fluidly connecting the outer surface to the lumen. Fluid is mixed around the cylindrical body, before entering the lumen through the plurality of apertures for additional mixing. The mixed fluid is then output from the lumen of the fiber tip fluid output device onto the fiber tip, for subsequent interaction with electromagnetic energy in an interaction zone above a target surface.
