  • Patent number: 4811736
    Abstract: A surgical drill is disclosed which includes an electric motor and an elongate tubular support sleeve. A drill bur is mounted so as to extend through the support sleeve and extend outwardly from the free end thereof, and the bur includes a shaft which mounts a plastic sleeve bearing for relative rotation therewith. The bearing contacts the internal bore of the support sleeve, so as to provide a seal therebetween which prevents the passage of debris past the bearing and into the support sleeve. Also, a portion of the plastic sleeve bearing is visible during use, and the bearing includes a distinctive color which is correlated to the particular configuration or size of the cutting tip of the bur, to thereby facilitate its identification during use of the drill.

  • Patent number: 4510627
    Abstract: A prosthesis for replacing part or all of the ossicles of the ossicular chain in the tympanic cavity. The prosthesis includes a porous body having an enlarged head for being closely associated with the tympanic membrane and having an elongated shaft for being coupled to the fenestra vestibuli. A metal core is encased within the body for collecting sound vibrations from the tympanic membrane and for transmitting the collected sound vibrations to the fenestra vestibuli. The metal core has substantially higher sound vibration and collecting qualities than the porous body.
