  • Air-driven dental vibratory instrument with a replaceable vibrator module
    Patent number: 6752629
    Abstract: An air-driven dental instrument (10) includes a replaceable vibrator module (16) detachably accommodated in an axial lodgment defined by an elongated outer casing (14) comprised of a frontal cap (22A) and a main body (26A) coupled with each other. When the cap (22A) is coupled, the module (16) is axially positioned against the cap (22A) by a positioning sleeve (90A) and is rotationally locked against the sleeve (90A) by a hexagonal formation (128) engaging into cutouts (136) formed on a housing (134). When the cap (22A) is disconnected from the main body (26A), the module (16) is retained by the housing (134) but is partly exposed therefrom. This permits a user to grip the module to thereby facilitate replacement of the module (16).
