Abstract
A medical or dental handpiece is provided with a temperature measurement device for measuring the temperature of the handpiece or a part of the handpiece described. The temperature measurement device can be designed to measure the temperature of the handpiece or a part of the handpiece in a contact less manner by detecting electromagnetic radiation, in particular heat radiation from heat sources associated with the handpiece. Alternatively, the temperature measurement device may be configured to measure the temperature of the interior of the handpiece that can be heated by at least one heat source. Alternatively, the temperature measurement device can be an electrical temperature measurement device.
Claims18
A dental handpiece for providing oral treatment, comprising:
- a shaft;
- a hollow outer sleeve with an interior space;
- a drive device for moving a connectable handpiece tool;
- bearings for said handpiece tool;
- a head part of said handpiece including an opening for inserting said connectable handpiece tool;
- a hollow head sleeve;
- a tool holder and actuator for actuating a tool release device for releasing said connectable handpiece tool;
- at least one temperature measurement device to measure a temperature of oral cavity tissue in a contact-less manner by measuring the electromagnetic radiation emitted from the oral cavity tissue;
- at least one additional temperature measurement device to measure a temperature of at least one heat source associated with the handpiece;
- a control and evaluation unit receiving temperature measurement signals from the temperature measurement device measuring oral cavity tissue and from the additional temperature measurement device measuring temperature of said at least one heat source, the control and evaluation unit evaluating the temperature measurement signals and providing a temperature dependent control signal to interrupt or otherwise control the operation of said handpiece upon reaching or exceeding a predetermined temperature limit value;
- a power source for supplying electrical power to said handpiece;
- and
- the control and evaluation unit generating control signals responsive to the evaluated temperature measurement signals and regulating operation of said handpiece in response to the evaluated temperature measurement signals.
A method for providing oral treatment with a dental handpiece, the method comprising:
- providing a dental handpiece comprising a shaft, a hollow outer sleeve with an interior space, a drive device for moving a connectable handpiece tool, bearings for said handpiece tool, a head part of said handpiece including an opening for inserting said connectable handpiece tool, a hollow head sleeve, and a tool holder and actuator for actuating a tool release device for releasing said connectable handpiece tool;
- providing at least one temperature measurement device to measure a temperature of oral cavity tissue in a contact-less manner by measuring the electromagnetic radiation emitted from the oral cavity tissue;
- providing at least one additional temperature measurement device to measure a temperature of at least one heat source associated with the handpiece;
- using a control and evaluation unit receiving temperature measurement signals from the temperature measurement device to measure temperatures of oral cavity tissue and to measure temperature of said at least one heat source, the control and using the evaluation unit to evaluate the temperature measurement signals and providing a temperature dependent control signal to interrupt or otherwise control the operation of said handpiece upon reaching or exceeding a predetermined temperature limit value;
- and
- using the control and evaluation unit generating control signals responsive to the evaluated temperature measurement signals and regulating a power source for supplying electrical power to said handpiece to control operation of said handpiece in response to the evaluated temperature measurement signals.
A method for providing oral treatment with a dental handpiece, the method comprising:
- dental handpiece means comprising a mechanism for releasably supporting a connectable handpiece tool rotable with respect to a handle, and having a tool release device for releasing said connectable handpiece tool;
- temperature measurement means capable of measuring a temperature of oral cavity tissue in a contact-less manner;
- at least one additional temperature measurement device to measure a temperature of at least one heat source of said handpiece;
- a control and evaluation unit receiving temperature measurement signals from the temperature measurement device to measure temperatures of oral cavity tissue and to measure temperature of said at least one heat source, the control and the evaluation unit evaluating the temperature measurement signals and providing a temperature dependent control signal to interrupt or control the operation of said handpiece upon reaching or exceeding a predetermined temperature limit value;
- and
- regulation means responsive to the control and evaluation unit to generate control signals responsive to the evaluated temperature measurement signals and to regulate a power source for supplying electrical power to said handpiece to control operation of said handpiece in response to the evaluated temperature measurement signals.
