Abstract
The present invention is directed to a dental mirror system having a fluid conduit to provide a stream of fluid across the surface of the mirror to remove material from the mirror surface. The dental mirror system can also be provided with a light-transmitting cable to illuminate the work area and/or a suction conduit to remove material from the mouth of the patient.
Claims1
A dental mirror system comprising:
- (a) an elongated arm defining an axis and having a distal end;
- (b) a mirror angularly secured to the distal end and having a reflective surface, associated with a viewing field, disposed at an obtuse angle relative to the axis of said elongated arm;
- (c) a fluid conduit extending along the length of said elongated arm and defining an orifice adjacent to the reflective surface of the mirror to provide a fluid stream across the reflective surface;
- (d) a light-transmitting cable extending along the length of said elongated arm in parallel relationship to said fluid conduit and having light-transmitting means adjacent to the reflective surface of the mirror and disposed to guide light in a direction incident to the reflective surface to illuminate the viewing field;
- and
- (e) a suction conduit extending along the length of said elongated arm in substantially parallel relationship to said fluid conduit and said light-transmitting cable, said suction conduit defining a suction opening adjacent to a surface of said mirror opposed to the reflective surface thereof so that activation of suction through said suction conduit can remove material from the mouth of a patient;
- said light-transmitting cable being slidingly received by said elongated arm and having said light-transmitting means adjacent to the reflective surface of the mirror.
