DENTAL OR SURGICAL HANDPIECE WITH AN RFID TRANSPONDER

The invention provides for a dental or surgical handpiece with an elongated handle sleeve (110) and a head piece (50) attached to the front end of the handle sleeve (110) that serves to to detachably receive a dental tool as well as for a clamping mechanism (20) formed in the head piece (50) to detachably hold the tool, the clamping mechanism (20) having a push-button (10) for actuating the clamping mechanism (20). The handpiece further has an RFID transponder (5) for identifying the handpiece. The push-button (10) consists of a heat-insulating electrically non-conductive plastic or m ceramic material with a plate-shaped recess that holds the RFID transponder (5). The push-button (10) has a flat round shape so that the RFID transponder (5), because of the equally flat round shape of its coil, can be integrated very well into it. Particularly advantageous ambient electrical conditions can be achieved for the RFID transponder as the push-button (10) is made of an electrically non-conductive material. An advantageous thermal insulation is provided as the push-button (10) is made of a heat-insulating material.
