Abstract:
A device for application in a sterile area for controlling an electric instrument provided in a non-sterile area, with the sterile area being separated from the non-sterile area substantially by a covering, wherein:at least one sensor responsive to the magnetic field is provided in the non-sterile area and a unit generating a magnetic field is provided in the sterile area, the at least one sensor responsive to the magnetic field and the unit generating a magnetic field are separated from each other at least by the covering means, the unit generating the magnetic field is disposed relative to the at least one sensor responsive to a magnetic field so that a variation of the magnetic field in space and/or time, which is induced by the unit generating the magnetic field, is detectable by the sensor responsive to the magnetic field and a sensor signal is generated, and controller unit is provided that generates a control signal for controlling the electric instrument in response to the sensor signal.
