Dependent claims

A dentistry instrument providing for observation of an operating area, comprising:

a handle having an axis defined therethrough;
a head mounted upon one end of said handle at a predetermined angle with respect to said axis of said handle and having a dental drill mounted within said head;
an optical observation window defined within said handle through means of which images of said operating area can be transmitted;
a video camera disposed within said handle and in optical observation window so as to receive an image of said operating area through means of said optical observation window;
reflecting means disposed within said handle and interposed between said optical observation window and said video camera for reflecting said image of said operating area, passing through said optical observation window, from said optical observation window to said video camera;
fiber optic means disposed within said handle for transmitting light from a light source to said operating area for illuminating said operating area;
a video system operatively connected to a second end of said handle, opposite said one end of said handle upon which said head is mounted, through means of a rotatable joint which permits said video system to be optically coupled to said video camera for transmission of a video signal from said video camera and for formation of a video image corresponding to said image of said operating area as transmitted through said optical observation window, reflected by said reflecting means, and received by said video camera;
a video monitor operatively connected to said video system for displaying said video image formed by said video system;
water spray means disposed within said handle and having an outlet defined within the vicinity of said optical observation window for spraying water toward said operating area;
and
compressed air means disposed within said handle and having an outlet defined within the vicinity of said optical observation window for exhausting compressed air outwardly toward said operating area.
