Gregory L. Van Hale has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6585512
    Abstract: A readily disposable aspiration unit that can be connected to various dental instruments of conventional design including ultrasonic scalers. The aspiration unit includes a novel suction means for automatically carrying away from the operative field cooling water and debris generated during the performance of the scaling procedure. The unit further includes a tip-encompassing shroud that uniquely functions as a suction scoop for automatically capturing aerosols in the operative field including aerosols containing saliva, blood, tissue, calculus and like adherent deposits, which are generated during the scaling procedure.
    Type: Grant

  • Patent number: 5554026
    Abstract: An aspirating dental hand piece having at its distal end a vacuum scoop that circumscribes the work tool and automatically carries away cooling water and debris during operation of the hand piece. The hand piece includes a two-part handle. The distal portion of the handle terminates in a suction scoop or shroud within which the gas driven motor is housed. This portion of the handle is divided into two portions, one of which houses the cooling fluid, gas and fiber optic conduits, and the other of which forms a fluid passageway in communication with the suction scoop for carrying away the cooling fluid and the debris generated during the drilling and grinding operations. The fluid and debris passageway is sealed with respect to the conduit carrying portion of the handle.

  • Patent number: 5531722
    Abstract: An aspiration unit that can be readily connected to an ultrasonic scaler of conventional design which includes a novel suction means for automatically carrying away from the work site cooling water and debris generated during the performance of the scaling procedure. The unit includes a transparent, tip-encompassing shroud that uniquely functions as a suction scoop for automatically capturing aerosols in the operative field including aerosols containing saliva, blood, tissue, calculus and like adherent deposits which are generated during the scaling procedure. The aspiration unit includes novel connectors that enable the unit to be removably connected to a conventional scaler so that the assemblage can be operated by the dentist using one hand without the aid of a dental assistant thereby decreasing the number of people exposed to any pathogens encountered during the scaling procedure.
