Abstract:
Output optical energy pulses including relatively high energy magnitudes (62, 68) and steep slope at the beginning (64,66 ) of each pulse are disclosed. As a result of the relatively high energy magnitudes which lead each pulse, the leading edge of each pulse includes a relatively steep slope. This slope is preferably greater than or equal to 5. Additionally, the full-width half-max value of the output optical energy distributions are between .025 and 250 microseconds and, more preferably, are about 50-70 microseconds. A flashlamp is used to drive the laser system, and a current is used to drive the flashlamp. A flashlamp current generating circuit includes a solid core inductor which has an inductance of about 50 microhenries and a capacitor which has a capacitance of about 50 microfarads. The output optical energy pulses cut target surfaces by interacting with fluid that is located above, on and/or in the target surface. Methods are disclosed for therapeutically treating tissue with pulses of electromagnetic energy.
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.
Abstract:
An electromagnetically induced cutting mechanism which can provide accurate cutting operations on both hard and soft materials is disclosed. The electromagnetically induced cutter is capable of providing extremely fine and smooth incisions, irrespective of the cutting surface. Additionally, a user programmable combination of atomized particles allows for user control of various cutting parameters. The various cutting parameters may also be controlled by changing spray nozzles and electromagnetic energy source parameters. A fluid conditioning system is adaptable to condition the water or air used in medical and dental cutting, irrigating, evacuating, cleaning, and drilling operations. The air or water may be conditioned by adding flavor, scent, saline, medications, and disinfectants. 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.
