摘要： A handle system for supporting a tool defining a tool axis during the performance of dental procedures comprises a handle defining a handle axis, a rotation sleeve, a head assembly and a gear set comprising first and second gear portions. The rotation sleeve supports the first gear portion. The head assembly supports the second gear portion. The handle supports the rotation sleeve for rotation relative to the handle. The handle supports the head assembly such that the first gear portion engages the second gear portion. With the head assembly supported by the handle, the head assembly engages the tool to support the tool such that the tool axis extends at a first angle relative to the handle axis and rotation of the rotation sleeve relative to the handle causes axial rotation of the tool about the tool axis.

摘要： A torque wrench, including: a head region with a receiving opening; a bending-resistant shaft region adjoins the head region; a support formed on the shaft region; and an actuating lever including an elastically bendable portion and a handle. The receiving opening receives a screwing instrument and defines an axis of rotation. The actuating lever, in resting position, is spaced apart from the in the circumferential direction to the axis of rotation. If a screwing instrument is inserted into the opening, the actuating lever transmits a torque. The wrench has an indicator region, which the exerted torque can be read as a result of the deflection of the actuating lever. When a reference force is reached, the bending portion comes into contact with the support. When a force is applied, the bending portion can be in the tightening direction and the torque can be read in the region.

摘要： Provided is a roller bearing in which a restraining force of a seal member is further strengthened. The roller bearing includes: an outer ring having an outer ring raceway surface on an inner peripheral surface; an inner ring having an inner ring raceway surface on an outer peripheral surface; a plurality of rolling elements rotatably arranged between the outer ring raceway surface and the inner ring raceway surface; and a seal member that is fixed to a seal attachment groove formed in an axially end portion of the outer ring by a snap ring and seals an axially end portion of a bearing internal space between the outer ring and the inner ring, in which an outer diameter of the seal member is larger than an outer diameter of the snap ring in the seal attachment groove, and in which a radially outer end portion of the seal member is sandwiched between an inner peripheral surface of the seal attachment groove and an outer peripheral surface of the snap ring.

摘要： In some embodiments, the current invention relates to a method and/or system for using a standard dental handpiece for endodontic cleaning. For example, a dental adapter is disclosed having a fitting for a standard dental handpiece, a torque limiter and/or a mount for an endodontic file. For example, the adapter may be single use and/or multi use. In some embodiments, the mount includes the torque limiter. For example, an endodontic file may be connected to the mount with a friction fitting that allows rotation of the file with respect to the mount at high torque. Optionally the mount is positioned eccentrically with respect to the fitting.

摘要： A lubrication information management device includes: a lubrication detector provided to a lubrication unit; an instrument wireless tag provided to an instrument; and a read-write unit which is either an antenna or a reader-writer. Moreover, the read-write unit communicates lubrication information to the instrument wireless tag when the lubrication detector detects any of lubrication of the instrument and an operation for lubrication. This makes it possible to reliably manage the lubrication of a dental instrument.

摘要： A manually-wound or charged, powered toothbrush includes a winding mechanism, an energy storage element, and an output gear train to cause a rotating, oscillating or sweeping brush head to move, thus improving the efficacy of the user's oral-care regimen. The toothbrush may include a removable, replaceable brush head that includes a clip that also serves as a removal tool for a spent brush head.

摘要： An ultrasonic dental handpiece system with rotary coupling comprising a dental handpiece and a dental handpiece tip wherein the system incorporates a swivel mechanism and dynamic fluid interface for the dental handpiece and dental handpiece tip to rotate freely relative to the dental handpiece cable thereby decoupling the handpiece from a torsion load applied to it by the handpiece cable and internal tubing and wires. The ultrasonic dental handpiece with rotary coupling generally includes a handpiece to which a piezo assembly and secondary coil are housed and a cable assembly including a primary coil and handpiece cable wherein the handpiece cable provides a supply of electrical energy and cooling lavage. The primary and secondary coils form a transformer wherein the secondary coil is inductively coupled to the primary coil with the secondary coil in electrical communication with the piezo assembly. A method of using a handpiece is also disclosed.

摘要： Different mechanical drive devices for a medical, dental or surgical tool are described that are designed to put the tool into an oscillating, rotational motion, wherein the oscillating, rotational motion comprises an alternating rotation of the tool by a first angle of rotation in a first rotational direction and by a second angle of rotation in a second rotational direction substantially opposed to the first rotational direction, wherein the first and second angles of rotation may have different values, so that during multiple sequential rotations in the first and second rotational directions, the tool cumulatively experiences a rotational motion in a preferred direction.
