LASER SHAVING Russian patent published in 2018 - IPC A45D26/00 A61B18/20 

FIELD: surgery.

SUBSTANCE: provided is a device configured to cut hair. Invention allows the devices to be smaller, lighter, and/or less costly to manufacture. Device configured to cut hair using laser light includes a handle portion and a shaving portion. Handle portion includes a battery and a laser light source. Laser light source is coupled to and configured to receive power from the battery. 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. Shaving portion includes a support and a single fibre optic supported by the support. Fibre 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. Fibre 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.

EFFECT: technical result is that the invention allows the devices to be smaller, lighter, and/or less costly to manufacture.
