MEDICAL OR DENTAL INSTRUMENT WITH A TEMPERATURE-MEASURING DEVICE

摘要

Medical or dental instruments, preferably handpieces, can have different temperature-measuring devices for measuring the temperature in the instrument or of at least a part of the instrument. The temperature-measuring devices can be designed, for example, to measure the temperature contactlessly by detection of electromagnetic radiation or to measure the temperature of an interior of the instrument that can be heated by a heat source. The temperature-measuring devices may be designed, for example, as electrical temperature-measuring devices or may have a magnetic material whose magnetic property is a function of temperature and/or has a temperature-dependent course. The temperature-measuring device may have, for example, an electrical switching device and a signal device wherein the signal device is switched at least between a first signal condition and a second signal condition when a temperature limit value is reached or exceeded or is underrun.

主权项

1. A medical or dental handpiece, comprising
a handpiece head having an outer shell defining an inner volume, a tool holder device for releasably holding a tool that can be connected to the handpiece, wherein the tool holder device is moveably arranged in the inner volume, at least one bearing unit operatively connected to the tool holder device to moveably support the tool holder device, wherein the at least one bearing unit is arranged in the inner volume, a drive device for setting in motion a tool that can be connected to the tool holder device, an electrical temperature sensor of a temperature-measuring device for measuring a temperature of at least one part of the medical or dental handpiece, wherein the electrical temperature sensor is arranged in the inner volume of the handpiece head, and an electric line or signal line connecting the temperature sensor of the temperature-measuring device to a unit comprising at least one of an evaluation unit for evaluating the measured signals of the temperature-measuring device, a regulating or control unit for temperature-dependent regulation or control of the medical or dental handpiece or a display unit for displaying the measured or determined temperature value or a temperature limit value, wherein the electric line or signal line extends out of the handpiece head to connect to the unit.
