Abstract
A fluid conditioning system is adapted to condition the fluid used in medical and dental cutting, irrigating, evacuating, cleaning, and drilling operations. The fluid may be conditioned by adding flavors, antiseptics and/or tooth whitening agents such as peroxide, medications, and pigments. In addition to the direct benefits obtained from introduction of these agents, the laser cutting properties may be varied from the selective introduction of the various agents.
Claims24
An apparatus using conditioned fluid to treat a tissue target, comprising:
- a fluid output pointed in a general direction of an interaction region, the fluid output being constructed to place conditioned fluid particles into the interaction region, the interaction region being defined at a location above the target and the conditioned fluid being compatible with the target;
- a flow-control cassette coupled to the fluid output and comprising a plurality of selectable passages coupled to pass the conditioned fluid with different flow rates;
- and
- an electromagnetic energy source pointed in a direction of the interaction region, the electromagnetic energy source being constructed to deliver into the interaction region a peak concentration of electromagnetic energy that is greater than a concentration of electromagnetic energy delivered onto the target, the electromagnetic energy having a wavelength which is substantially absorbed by the conditioned fluid in the interaction region, wherein the absorption of the electromagnetic energy by the conditioned fluid energizes the fluid causing the fluid to expand and wherein disruptive forces are imparted onto the target.
The apparatus as set forth in claim wherein:
- the conditioned fluid comprises a disinfectant;
- and
- a composition of the disinfectant within the conditioned fluid particles is suitable for use on the target in combination with the electromagnetic energy for generation of the disruptive forces.
The apparatus as set forth in claim wherein the conditioned fluid consists of sterile water.
