Attorney, Agent or FirmInternational ClassA61C 003/00AbstractA handpiece assembly is disclosed for use with a dental laser assembly of the type having a laser and an elongated optical fiber assembly. The optical fiber assembly has a proximal end which receives radiation from the laser and a distal end which delivers the laser radiation to a target site. The handpiece assembly includes an elongated handpiece which is dimensioned to be held in a human hand. A longitudinal throughbore is formed in the handpiece and is dimensioned to slidably receive the optical fiber assembly so that the distal end of the optical fiber assembly extends outwardly from one end of the handpiece. A locking assembly removably locks the other end of the handpiece against longitudinal movement to the optical fiber assembly. Furthermore, the entire handpiece assembly is discarded after use on a single patient to prevent disease transmission by the handpiece. | |
