Abstract

A mouth prop and tongue retractor apparatus for use in dental procedures. The apparatus includes a handle rotatably mounted within a base. A ball joint on the base fits within a socket in a mouth prop to provide pivotal positional adjustment of the apparatus. An elongated aspirator tube extends through the handle and base, and is coupled to a tongue retractor. A suction aperture on the tongue retractor communicates with the aspirator tube and provides for saliva removal from a patient'"'"'s mouth. Rotation of the handle provides extension adjustment for the aspirator tube and tongue retractor.

Claims

(f) gimbal adjustment means for adjustably positioning said tongue retractor means and said suction means relative to said mouth prop; and

(g) extension adjustment means for positioning said tongue retractor means and said suction means relative to said handle and said base.

2. An apparatus as recited in claim 1, wherein said suction means comprises an aspiration tube, said aspiration tube coupled to said tongue retractor means, said suction means further comprising a suction aperture on said tongue retractor means, said aspiration tube in flow communication with said suction aperture.

3. An apparatus as recited in claim 2, wherein said handle includes a bore and wherein said ball joint includes a bore, said bore in said handle positioned collinear with said bore in said ball joint, said aspiration tube extending through said bore in said handle and said bore in said ball joint.

4. A mouth prop and tongue retractor apparatus as recited in claim 3, wherein said extension adjustment means comprises an internal threaded portion in said bore in said handle and an external threaded portion on said aspiration tube, said threaded portion in said bore in said handle engaging said threaded portion on said aspiration tube.

5. A mouth prop and tongue retractor apparatus as recited in claim 4, wherein said extension adjustment means further comprises means for aligning said aspiration tube relative to said base and said handle and preventing rotation of said aspiration tube relative to said base AND said handle.

6. A mouth prop and tongue retractor apparatus as recited in claim 2, wherein said tongue retractor means further comprises a detachable plate, said suction aperture included on said detachable plate.

7. A mouth prop and tongue retractor apparatus as recited in claim 6, wherein said tongue retractor means further comprises retention means for retaining said plate when detached from said tongue retractor.

8. An apparatus as recited in claim 1, wherein said gimbal adjustment means comprises a ball joint included on said base and a socket included in said mouth prop, said ball joint pivotally coupled to said socket.

9. A mouth prop and tongue retractor apparatus, comprising:

(a) a handle, said handle including an axial bore;

(b) a base, said base including a ball joint, said ball joint including an axial bore, said handle rotatably coupled to said base;

(c) a mouth prop, said mouth prop including a socket, said ball joint pivotally coupled to said socket;

(d) an aspiration tube, said aspiration tube extending through said axial bore in said handle and said axial bore in said ball joint;

(e) a tongue retractor, said tongue retractor including at least one suction aperture, said tongue retractor coupled to said aspiration tube; and

(f) extension adjustment means for positioning said tongue retractor relative to said handle and said base by rotation of said handle relative to said base.

10. An apparatus as recited in claim 9, wherein said extension adjustment means comprises an internal threaded portion in said bore in said handle and an external threaded portion on said aspiration tube, said threaded portion in said axial bore in said handle engaging said threaded portion on said aspiration tube.

11. An apparatus as recited in claim 10, wherein said extension adjustment means further comprises alignment means for aligning said aspiration tube relative to said base and preventing rotation of said aspiration tube relative to said base.

12. An apparatus as recited in claim 11, wherein said alignment means comprises a keyway alignment member, said keyway alignment member positioned on said base, said keyway alignment member including an axial bore, said bore in said keyway alignment member being collinear with said bore in said ball joint and said bore in said handle, said aspiration tube mounted within said bore in said keyway alignment member, said bore in said keyway alignment member including an axial groove, said aspiration tube including an axial key, said key on said aspiration tube slidably engaging said groove in said bore in said keyway alignment member.

13. An apparatus as recited in claim 9, wherein said tongue retractor means further comprises a detachable plate, said suction aperture positioned on said detachable plate, said suction aperture positioned in flow communication with said aspiration tube, said tongue retractor including retention means for retaining said detachable plate.

14. A mouth prop and tongue retractor apparatus, comprising:
