Abstract: A dental laser assembly is disclosed for use in eradicating carious lesions in teeth, the treatment of sensitive teeth, as well as the removal of soft tissue, the incising of the frenum, opurculum, anesthesia of the tooth, etching enamel for restorations or orthodontic appliance fixation, the welding of fixed prosthesis, removal of bacterial flora periodontal pockets, removal and/or vaporization of healthy or necrotic pulp, the vertical and/or horizontal condensation of gutta percha or any other root canal sealant, the cauterization of blood vessels in the oral cavity, vaporizing bone tissue, removing tartar, apical fusion of foramina, enlarging and shaping root canal, removing carbon from surface of teeth, removal of enamel, bleaching teeth, etching dentin, separating orthodontic brackets, merging hydroxyapatite to bone and enamel, amalgam removal and undercutting of carious and/or healthy dentin and/or camentum. The laser assembly includes a housing having a cavity in which a pulsed laser is contained. The laser is excited so that the laser emits a laser beam along a predetermined axis that is in line with a fiber optic delivery system and at a pulse rate of one to 10,000 pulses per second and an average power variable from one tenth to 50 watts. A handpiece is dimensioned to be inserted into a human mouth while an optical fiber optically connects the laser output to the handpiece. The laser assembly also includes a continuous output aiming laser which, upon activation, provides a continuous laser aiming beam coaxial to the treatment beam. Both beams are then introduced into a fiber optic delivery system.

Abstract: A microsurgical laser device for guiding a laser beam to a desired target. The device includes a laser head that is vertically oriented and which is supported by a base that contains the required electronics for the system. This laser head can be tilted in all directions so as to position the device for use. The laser head is coupled to an articulated delivery system that allows for the delivery system, including a colposcope or an operating microscope, to be raised, lowered, tilted, rotated, and focused onto the target.The articulated connection from the laser head to the colposcope or operating microscope makes use of a minimum number of mirrors to redirect the laser beam at 90 degree angles along a direction perpendicular to the axis of the incident path. Each mirror is mounted on precision mounts that obviate the need for adjustments.In one embodiment of the device the articulated system makes use of three mirrors to redirect the beam and one lens to provide a fixed laser spot size at the target. In another embodiment of the device, four mirrors are used and two lenses are employed in order to provide a variable laser spot size at the target.

Abstract: Microsurgical laser device for guiding a laser beam to a desired target. The device includes a laser head supported in a relatively horizontal orientation by a counterbalanced articulated support arm which provides for elevational positioning of the laser head as well as rotation of the laser head about two parallel spaced apart vertical axes. The support arm, in turn, is rotatably supported by a vertical post defining a third vertical axis.Threadably connected to one end of the laser head is an articulated laser guide arm having a precision telescopic first section followed by four rotatable mirror sections each of which is adapted to redirect a beam 90.degree. along a plane perpendicular to the axis of the incident path. Each section is precision made to obviate the need to adjust the mirror or align the arm.The support arm permits easy approximate positioning of the laser head in the vicinity of the laser beam target while the relatively short pre-aligned articulated laser beam guide provides for quick precise aiming of the laser beam.The vertical post is supported by a base cabinet that contains the power supplies. The controls of the laser beam characteristics such a power level and time of exposure are contained on a moveable control console that is separate from the base cabinet.

Abstract: A fiber optic probe and its use in performing a sclerostomy (forming a small hole in the sclera of an eye) as a treatment for glaucoma. The minimally dimensioned probe is designed to direct laser light out of its side and, as a result, allows a sclerostomy procedure to be performed with minimal trauma to the conjunctiva and other surrounding ocular tissues of the patient. A series of pulses of infrared laser radiation delivered through the side of the probe forms the hole in the sclera.

Abstract: A dental abrasion arrangement includes a pressure vessel that has an inlet port and an outlet port. A source of pressurized propellant gas is attached to the inlet port and a dental abrasion tool is attached to an outlet port of the pressure vessel. Abrasive powder is ejected from the pressure vessel and to the abrasion tool via a discharge assembly and the outlet port. A feeding and metering auger is mounted within the pressure vessel. The auger is mounted substantially horizontally within the pressure vessel. The auger is driven by a motor, so that the abrasive powder within the pressure vessel is fed to the discharge assembly as the motor causes the auger to rotate. The rotation of the auger, and thus the feed rate of powder to the tool, is preferably adjusted by a controller, which controls the rotation of the motor, preferably according to pre-determined profiles that take into account parameters such as the geometry of the auger and the dental tool, as well as variables such as the internal pressure in the pressure vessel. The outer casing of the pressure vessel can be made so small that it can be mounted on a standard dental tray, or on a supporting arm of a dental chair.
