Surgical instrument RFID tag reading apparatus (10) comprises; an RFID tag reader (16); RF antenna (18); guidance apparatus (22); a controller (24); an interrogation zone (12) for receiving a plurality of surgical instruments (14), each having a respective RFID tag containing identification information. The guidance apparatus is arranged to cause predetermined relative movement between the RFID tags and an RF signal (20). The controller is arranged to: receive a signal from the RFID tags on the instruments; compare the received information with a surgical instrument list; determine whether identification information has been received for each of the surgical instruments on the list, and if not, generate an incomplete list alert. The guidance apparatus may be a conveyor belt, which may vary the speed of the RFID tags, and may rotate, tilt or shake the tags to improve the detection of individual RFID tags. There may be an additional RF antenna (Fig. 10, 102) situated below the conveyor belt. |
