MULTI-PURPOSE DENTAL INSTRUMENT

摘要

A dental mirror instrument has a light waveguide and an airflow conduit that extend along the length of an elongated member to a mirror portion. An airflow exiting from the airflow conduit may be directed over the mirror surface to remove fluids and debris. Light from a light source is transmitted, along the light waveguide and is reflected off of a back-side of a land portion through a Fresnel lens to produce a task light. A mirror may have a hydrophobic surface and this surface may have raised portions or a patterned surface that further enhances the removal of fluids or debris. The optical component of the dental instrument may be detachable to a source component and may be disposable. A flexible connector may be coupled with the source component to provide an airflow to the airflow conduit and/or electrical power to the light source.

主权项

1. A dental instrument comprising:
a) an optical component comprising;
i) a mirror portion comprising;
1) a mirror;2) a mirror surface;3) a mirror plane axis;ii) an elongated member having a length and a length axis from an engagement end to a mirror end;iii) a light waveguide extending along the length of the elongated member having an engagement end for receiving light from a light source and configured to transmit said light along the light waveguide to the land portion;iv) an airflow conduit extending along the length of the elongated member having an airflow aperture configured at the mirror end for dispensing a flow of air over the mirror surface;v) a land portion configured between the elongated member and the mirror portion having a front-side and a back-side, and comprising:
1) a Fresnel lens positioned on the front-side of said land portion comprising a plurality of ridges extending across the land portion in a substantially perpendicular direction to the length axis of the elongated member; wherein the Fresnel lens is configured to emit a reflected light from the back-side of the land portion from the optical component to produce a task light; wherein the ridges comprise a step and a rise, wherein the rise is a planar surface that extends substantially perpendicularly to a reflected light from the back-side of the land portion; and wherein the step is a planar surface that extends substantially parallel to a reflected light from the back-side of the land portion.
