Dental equipment comprises CPU for setting and monitoring correct functioning of dental tool

The motor (2) driving a dental tool (17) is controlled by a CPU (1). This has reference setting potentiometers (11) for the load exerted by the tool, (12) for the duty factor and (13) for a reference position. A measurement circuit (7) measures the length of a root canal and a resistor (6) acts as a...

Summary:The motor (2) driving a dental tool (17) is controlled by a CPU (1). This has reference setting potentiometers (11) for the load exerted by the tool, (12) for the duty factor and (13) for a reference position. A measurement circuit (7) measures the length of a root canal and a resistor (6) acts as a load sensor. Direction of rotation is selected by a switch system (5). The computer provides a visual display (8) of operating conditions with audible indication if the set reference values are exceeded and can switch off the motor transistor switch (3). Es wird eine Dentalausrüstung zum Beschneiden von Zähnen, Herstellen von Wurzelkanälen usw. angegeben. Das Dentalgerät verfügt über Folgendes: ein Betätigungselement (2) zum Betätigen eines Schneidwerkzeugs (17); einen Lastsensor (1, 6) zum Erfassen einer am Schneidwerkzeug (17) wirkenden Belastung und eine Lastanzeigeeinrichtung (8), die dafür sorgt, dass eine Bedienperson über die vom Lastsensor (1, 6) erfasste Belastung visuell, hörbar und/oder taktil informiert wird.
