ABSTRACT:
The invention relates to a device for supplying electrical energy to an electro-pen with an electric drive unit for driving a tool. The device comprises a console with an energy supply unit having an accumulator for supplying the electrical drive unit with electrical energy. The console may be configure to be sterilized by steam having a housing and electrical components that are sealed liquid-tight. The accumulator may include a sterile covering for sterile introduction into the console. A coupling between the console and the electro-pen carries the supply of electrical energy from the console to the electro-pen. The coupling may be an electrical contact in the form of a sterilizable connector or an inductive coupling. The console may be configured to store energy and is thus mobile, or the console may include a connection for connecting to a mains or external power supply for charging the accumulator. The console may include a switch-mode power supply for charging the accumulator. The console may include a holder for receiving and charging the electro-pen. The electro-pen includes an electrical storage device and a coupling for receiving the electrical energy supply from the accumulator. The holder may include an electrical coupling between the console and the electro-pen in which at least two electrical contacts and at least one transformer are disposed about each the holder and the electro-pen. Alternatively, the holder may include an inductive coupling in which at least one transformer having at least one coil is disposed about each the holder and the electro-pen.
