The improvement comprises a protective shield at the end of the handpiece displaceable from a first position preventing the passage of the laser beam to a second position allowing the laser beam to pass. Preferably, the protective shield includes two prongs located at the end of the handpiece and capable of relative lateral displacement thereby providing the effect of an improved laser scalpel.Field of SearchHaving means to emit radiation or facilitate viewing of the workHaving handles to pivot surface (e.g., pliers) METHOD OR MATERIAL FOR TESTING, TREATING, RESTORING, OR REMOVING NATURAL TEETH MISCELLANEOUS Beam energy control or monitoring Applicators Placed in body With beam shaping or redirecting (e.g., lens) | |
