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.

First claim

The invention claimed is:

1. A surgical device comprising:
a surgical application part with an electric motor having motor windings;
an electrical supply cable having a plurality of lines; and
at least one readout antenna which is integrated in the surgical application part or the electrical supply cable,
the electrical supply cable being connectable at a first end to the surgical application part and at a second end to a control unit for controlling the electric motor,
the at least one readout antenna being capable of being supplied with voltage and being designed as an additional element separate from the motor windings,
the at least one readout antenna adapted to excite and read out an RFID chip arranged or arrangeable near the at least one readout antenna to transmit data bidirectionally between the RFID chip and the control unit via the electrical supply cable.

2. The surgical device according to claim 1 , wherein the at least one readout antenna and the RFID chip are arranged or arrangeable at a distance from each other of less than or equal to 1 cm.

3. The surgical device according to claim 1 , wherein the at least one readout antenna is meander-shaped or spiral-shaped or coil-shaped or helix-shaped.

4. The surgical device according to claim 1 , wherein the plurality of lines comprises three lines.

5. The surgical device according to claim 4 , wherein the motor windings comprise three motor windings configured to be supplied with current and driven via the three lines.

6. The surgical device according to claim 1 , wherein the RFID chip is integrated in the surgical application part.

7. The surgical device according to claim 1 , wherein the surgical application part has a plurality of application-part plug contacts and the electrical supply cable has a plurality of supply-cable plug contacts, wherein the application-part plug contacts and the supply-cable plug contacts are engageable with each other in order to couple the surgical application part to the electrical supply cable.

8. The surgical device according to claim 7 , wherein when the surgical application part and the electrical supply cable are coupled to each other, at least two electrical switching positions are adjustable, the at least two electrical switching positions comprising an OFF position and an ON position, wherein in the OFF position the at least one readout antenna gets or is supplied with voltage and the RFID chip can thus be excited and read out, and wherein in the ON position the at least one readout antenna is not supplied with voltage.

9. The surgical device according to claim 8 , wherein the application-part plug contacts are pin-shaped and at least one application-part plug contact has two independent, different contact zones for different switching-circuit driving in the ON position and the OFF position.

10. The surgical device according to claim 8 , wherein the supply-cable plug contacts are socket-shaped and at least one supply-cable plug contact has two independent, different contact zones for different switching-circuit driving in the ON position and the OFF position.

11. The surgical device according to claim 1 , wherein the at least one readout antenna comprises a first readout antenna and a second readout antenna, wherein the second readout antenna is provided in the surgical application part, wherein an accessory is attachable or is attached to the surgical application part, and wherein the accessory has a further, second RFID chip configured to be excited and read out via the second readout antenna.

12. The surgical device according to claim 8 , wherein in the ON position a switching circuit or circuit containing the at least one readout antenna gets or is short-circuited and is thus taken out of operation.
