| 摘要 |
<p>A magnetic coupling system (110a) comprising a magnetic assembly for removably combing a base structure (102) and a tool insert (104) is described. This arrangement allows energy from a transducer (106) located in the base structure to be transmitted through the magnetic assembly to the tool insert. In one embodiment, the magnetic assembly comprises one or more magnetic inserts (122a) located between the base structure and tool insert and a permanent magnet (120) or an electromagnet located proximate to the one or more magnetic inserts. The permanent magnet can be axially polarized, radially polarized or polarized at any intermediate angle. In one embodiment, the two components being coupled are a wave guide (108) in direct contact with an ultrasonic motor and a dental scaling tool. In this embodiment, vibrational motion is transferred from the acoustic extension to the tool insert.</p> |
