Paper Abstract

Many laser medical procedures can be improved by dispensing exogenous fluids onto the tissue during irradiation. Examples include the dispensing of coolants, photoabsorptive enhancers, photoreflective tissue shields, photoactivated tissue solders, fillers, or surface sealants. The main obstacle to the use of such auxiliary fluids is the difficulty of dispensing them in a convenient, interactive fashion while operating the laser. We have adapted ink-jet printing technology to this problem of dispensing auxiliary fluids during laser procedures. The technology can dispense fluids with exquisite volumetric, spatial, and temporal precision. In principle, one or more fluids can be dispensed interactively from nozzles similar in size to the optical fibers and microlenses that are used for the lasers. Compact handpieces or endoscopic tools that will incorporate fluid MicroJets and laser optics can be envisioned. The enhancements to laser surgical technology that could be afforded by the use of fluid jetting will be discussed. Examples from ongoing work in dentistry, orthopedics, and dermatology are presented. Supported in part by NIH SBIR's DE10687 and GM50602.
