  • Publication number: 20170151036
    Abstract: An instrument that includes a tod; a tool-holder; complementary means for vibrational coupling of the tool to the tool-holder which can be activated by relative movement of the tool and the tool-holder along a vibrational coupling/uncoupling stroke; and complementary rclcaaable means for attaching the tool to the tool-holder allowing, when the tool is attached to the tool-holder, the vibrational coupling/uncoupling stroke. The attachment means may include two attachment members, male and female, which can be attached together by relative movement along an attachment/detachment stroke. The attachment members cannot be deformed during the attachment/detachment stroke. The stroke includes an axial component and a component in a plane substantially transverse to the axial component, referred to as the transverse component.

  • Patent number: 9421072
    Abstract: A vibratory instrument includes a tool releasably mounted on a tool carrier designed to be coupled with a vibration generator device. The tool includes in succession along a longitudinal axis: a working portion presenting a free end for reproducing the vibration transmitted by the vibration generator device; a coupling portion; and an elastically-deformable attachment portion disposed upstream from the coupling portion. The tool carrier includes in succession along a longitudinal axis: a housing receiving the attachment portion of the tool; and a coupling bearing surrounding the coupling portion of the tool, at least in part. The attachment portion of the tool presents outside dimensions that are adapted relative to the inside dimensions of the housing of the tool carrier to prevent contact between the attachment portion and the housing when the coupling portion of the tool is in contact with the coupling bearing of the tool carrier.

  • Patent number: 8202087
    Abstract: Vibratory tip (100) including a body (110) having a first end (111) adapted to be mechanically coupled rigidly with a surgical handpiece (101) generating vibrations and a second end to which there is fixed a tool holder (112) intended to reproduce the vibrations transmitted by the handpiece. The tip furthermore includes a tool (120) with a working area (121). The tool (120) is freely rotatably mounted relative to the tool holder (112), which allows the tool to adjust itself automatically in order to remain in contact with the tooth and position the working area on the entire periphery of the tooth with a single tip. The tool preferably includes two working areas to improve keeping and guiding the tool on the surface of the tooth to be treated.
