Abstract: A laser surgical instrument uses a CO.sub.2 laser source and an articulated arm structure to maintain single mode transmission of a 10.6 .mu.m beam to probe. In one configuration, high power is maintained for photo-transection and/or photocauterization. A second probe embodiment introduces other degrees of functionality such as aspiration, irrigation and internal viewing. Internal illumination is achieved by using the sheaths of quartz waveguides to transmit visible light while the laser beam is propagated internally in the waveguide structure.

Abstract: An abnormality detection system for highly precise detection of an abnormality in a laser treatment device includes a laser transmission tube coupled with a laser treatment unit, oscillating laser light, a discharge-side water pressure sensor, and a water pressure detection liquid surface level meter detecting a change in a pressure of cooling water flowing through forward-direction and a backward-direction spaces in the laser transmission tube. The laser transmission tube includes a hollow wavelength path having a lightguide space formed in a longitudinal direction, and an outer case enclosing an outer circumferential surface of the hollow waveguide path and extending in the longitudinal direction. The discharge-side water pressure sensor and the water pressure detection liquid surface level meter detect the change in the pressure of the cooling water flowing through in a forward-direction space and a backward-direction space to detect any abnormality.

Abstract: A device for laser lipolysis is described, comprising a treatment laser source adapted to emit radiation within a wavelength range strongly absorbed by the human body adipocytes. The device further comprises a hand-piece having a handle and a cannula that is adapted to be inserted into an adipose tissue of a patient undergoing a lipolysis treatment. An optical fiber is adapted to connect the laser source to the hand-piece, and the cannula is adapted to receive a distal portion of the optical fiber. The device further comprises a detection system, for detecting the movement speed of the hand-piece when in use, and a control unit, functionally connected to the treatment laser source and adapted to control at least one emission parameter of the treatment laser source, so as to modulate the power emitted by the treatment laser source based on the movement speed of the hand-piece detected by the detection system. The device also comprises a signaling system adapted to signal to an operator a condition of anomalous movement speed.

Abstract: Systems and methods for adjusting an angle of incidence of a laser surgery system include a laser source to produce a laser beam and an optical delivery system to output the laser beam pulses to an object at an adjustable incident angle. A first rotator assembly receives the beam from the laser source along a first beam axis. The first rotator assembly rotates around the first beam axis and the first rotator assembly outputs the beam along a second beam axis different from the first beam axis. A second rotator assembly receives the beam from the first rotator assembly along the second beam axis. The second rotator assembly rotates around the second beam axis. The second rotator assembly follows the rotation of the first rotator assembly and the first rotator assembly is independent of the rotation of the second rotator assembly.

Abstract: A device configured to cut hair using laser light includes a handle portion and a shaving portion. The handle portion includes a battery and a laser light source. The laser light source is coupled to and configured to receive power from the battery. The laser light source is also configured to generate laser light having a wavelength selected to target a predetermined chromophore to effectively cut a hair shaft. The shaving portion includes a support and a single fiber optic supported by the support. The fiber optic has a proximal end, a distal end, an outer wall, and a cutting region positioned towards the distal end and extending along a portion of the side wall. The fiber optic is positioned to receive the laser light from the laser light source at the proximal end, conduct the laser light from the proximal end toward the distal end, and emit the light out of the cutting region and toward hair when the cutting region is brought in contact with the hair.

Abstract: A dental laser treatment system includes a treatment laser beam and a pilot (e.g., aiming/marking) laser beam sharing a collinear beam path, where the beam path is guided by a guidance system through a handpiece/main chamber assembly having a beam exit. A laser beam presence detector is removably affixed to or within the handpiece/main chamber assembly. The laser beam presence detector provides feedback to a computer which can control actuation of the treatment laser beam and the pilot laser beam, and the beam guidance system. The computer performs a search for determining the center location of the beam exit based on the feedback and controls the beam guidance system to guide the beam path approximately to the center of the beam exit, thereby providing automatic alignment of the laser beam with the beam exit or an optional hollow waveguide.
