Components of Assembled Handpieces
The following figure shows the items that comprise a handpiece.
Handpiece
The handpiece consists of a connector, a cable, a handpiece body, and a
connecting body (refer to Figure 8-1). The connector attaches the cable to
the CUSA EXcel console. The inside of the cable contains cooling water
tubes and electric wires, allowing the console to supply water to cool the
handpiece and electric power to drive the handpiece.
The handpiece body contains these working items:
• An electric coil, which creates a magnetic field that excites the
transducer.
• A transducer, which converts electric energy to mechanical motion.
• Cooling water tubes; the water removes the heat generated by the
transducer in the energy conversion.
The connecting body serves as the connecting point for the tip and
transfers the vibrations from the transducer to the tip.
Remember:
• The 23 kHz handpieces are gray with green connectors.
• The 36 kHz handpiece is black with a blue connector.
