Abstract

Methods and apparatus are presented for extracting and collecting bone marrow from the jawbone of a patient before, during, or after dental procedures. The method and apparatus further provides a readily accessible, and easily harvested, source of bone marrow without the drawbacks of current extraction methods.

Claims

1. Apparatus for extracting bone marrow from an extraction site comprising:

a housing having a cavity and a passageway for transporting bone marrow from the cavity to a collection device, said bone marrow passageway having a proximal end in communication with the cavity and a distal end in communication with a suction tube;

a shaft disposed in the cavity;

a bur attached to a first end of the shaft;

a beveled gear attached to a second end of the shaft;

a drive gear matingly engaged to the beveled gear; and

a tube disposed within the housing for delivering liquid to said extraction site.

2. Apparatus in accordance with claim 1 further including:

a suction tube having a first end connected to said bone marrow passageway distal end; and

a second end connected to a vacuum source.

3. Apparatus in accordance with claim 1 wherein said tube for delivering liquid comprises a second passageway in said housing.

4. The apparatus of claim 1, wherein the shaft disposed within the cavity is hollow and said tube for delivering liquid to the extraction site is disposed within the hollow shaft.
