DENTAL TREATMENT SYSTEM HAVING MULTI-WAVELENGTH LASER APPLYING HANDPIECE

摘要

According to an embodiment of the present invention, an oral cavity treatment system including a multi-wavelength laser emitting hand-piece includes: a power supply unit generating driving power; multiple laser diodes which generates laser beams of a unique wavelength as the driving power is applied; a switching circuit which controls the driving powder to be applied to one of the laser diodes; multiple optical fibers transmitting each laser beam generated by the laser diodes; a coupling unit integrating the optical fibers to a single optical fiber; the single optical fiber transmitting the respective laser beams transmitted through the coupling unit; and the hand-piece held by an operator and including a focusing lens optical structure unit receives the laser beam from the single fiber on a side and emits the laser beam to the treatment target tissue through the other end.
