1. An apparatus for registering surgical instruments each provided with at least one RFID transponder during a reprocessing of the surgical instruments in a reprocessing unit for medical products and/or during a count check in an operating room, with
a receiving space, wherein a lower side of the receiving space is delimited by a bottom, all sides of the receiving space are delimited by side walls and at least one of the surgical instruments can be introduced into the receiving space through an upper side of the receiving space,
a shielding which is arranged at or in the bottom and the side walls in such a way that the receiving space is shielded at the bottom and sides from external electromagnetic waves,
an antenna device which is configured within the shielding in at least two side walls of the side walls delimiting the receiving space and extending transversely to and/or parallel to one another in such a way that the antenna device can transmit electromagnetic waves into the receiving space and receive electromagnetic waves from the receiving space for communication with an RFID transponder at least with respect to two different sides of the receiving space, and
an identification device which is configured, in a case in which at least one of the surgical instruments is introduced into the receiving space, to be able to identify the at least one of the surgical instruments introduced into the receiving space by means of the antenna device and to be able to store identification data corresponding to an identification of the at least one of the surgical instruments introduced into the receiving space.
