Abstract:
1. A medical tool for dental treatment comprising: a base unit, said base unit includes (1) a laser module of a diode laser, (2) a laser module of an erbium:YAG laser, (3) a coolant source, and (4) control circuitry; a rear unit connected to the base unit via a common line, said rear unit includes (1) an optical element, (2) a hollow waveguide, (3) a transfer piece, and (4) switch elements for function selection; and said common line comprises (1) a first connection line connecting the laser module of a diode laser to the optical element, (2) a second connection line connecting the laser module of an erbium:YAG laser to the hollow waveguide, (3) a third connection line connecting the coolant source to the transfer piece, and (4) a fourth connection line for connecting the control circuitry to the switch elements for further selection; and a plurality of separate handpieces selectively fittable to the rear unit, wherein each of said plurality of separate handpieces includes at least one of the following: (a) a light guide connectable to the first connection line for the diode laser; (b) a light guide connectable to the second connection line for the erbium:YAG laser; and (c) a coolant line connectable to the third connection line for the coolant source; wherein a single handpiece is selected from the plurality of separate handpieces and secured to the rear unit depending on treatment to be performed.
