    摘要: A dental handpiece has a head section, a neck section, a grip section connected to the grip section, and a drive unit connected to the grip section. The handpiece also has a detent unit for preventing relative rotation between the neck and grip sections. The detent unit includes a detent pin arranged axially slidably in the grip section, a spring for biasing the pin proximally so that the distal end of the pin is arranged inside the grip section in a rest position, and a catch formed at the proximal end of the neck section for receiving the pin for engagement. When the drive unit is brought into connection to the grip section, the pin is pressed distally to project out of the grip section into engagement in the catch, to thereby prevent relative rotation between the neck section and the grip section.

    摘要: A system for enhanced sealing against intrusion of moisture and other contaminants for medical/dental handpieces having rotating or other moving elements driven by a motor within the handpiece. The enhanced sealing includes tandem seals on stepped diameters to provide additional flow pathway impediments. The tandem seals preferably include spring seals that are positioned in opposite directions to provide enhanced sealing against pressures in two different directions that occur during the pressurization and vacuum cycles of an autoclaving process. Additional enhancements include the use of annular sealing rings with x-shaped cross sections.

    摘要: A handheld pneumatic medical device, such as a dentist handpiece, is provided for rotating a bur about an axis. Importantly, the device utilizes the boundary layer effect to transfer energy from the fluid flow to rotation of the bur. As a result, the device is operated without creating high decibel noise. Structurally, the device includes a housing defining a chamber, and a hub mounted for rotation in the chamber. When engaged with the hub, the bur passes through a distal aperture in the housing. The housing is further provided with a port for introducing a fluid into the chamber substantially tangential to the axis. Also, the device includes disks connected to the hub and substantially perpendicular to the axis. Operationally, boundary layer effect forces between the fluid flow and the disks cause the hub and the bur to rotate about the axis.

    摘要: A surgical instrument having an electric motor is discussed. The motor includes a motor output member, a driven member and a driving member. The driven member is coupled to the motor output member. The driving member includes a winding and a magnetically conductive portion comprising a plurality of laminations. The winding can be a self-supporting winding. The driving member, or at least the magnetically conductive portion thereof, is disposed proximate the driven member such that energizing the driving member imparts motion to the driven member. At least a portion of the driven member includes a magnet material. The magnet material can have a remanence of greater than or equal to about 1 T.

    摘要: A dental handpiece, which has a drive motor part connected to a housing and a head part with a socket for supporting a tool for rotation being releasably secured on the housing, characterized by the handpiece being convertible between an angled handpiece and a straight handpiece. This is accomplished by the housing being composed of a first housing member, a second housing member, a device for interconnecting the first and second housing members for swivel movement between a first position with their drive shaft sections extending at an angle to each other and a second position with the drive shaft sections being in axial alignment, and a device for holding the housing members in a selected one of the first and second positions. The head part has a sleeve of a configuration to telescopically cover the second housing member and the majority of first housing member while the members are held in one of the first and second positions so that by changing the head part to provide another head part having a sleeve with a different configuration, the handpiece is converted between an angled handpiece and a straight handpiece.
