Abstract

A surgical device includes a surgical application part having an electric motor with motor windings and an electrical supply cable having a plurality of lines. The electrical supply cable can be connected to the surgical application part at a first end and to a control unit for controlling the electric motor at a second end. The surgical device includes at least one readout antenna which is integrated/provided in the surgical application part or the electrical supply cable. The at least one readout antenna can be supplied with voltage and, as an additional element separate from the motor windings, can activate and read out an RFID chip that is/can be arranged near to the at least one readout antenna, in order to transmit data bidirectionally between the RFID chip and the control unit via the electrical supply cable.
