Surgical item managing method and surgical item managing system for smart operating room

1. A surgical item managing method for a smart operating room, for use by a surgical item managing system for the smart operating room to manage a surgical item used during a surgical procedure, the surgical item comprising a flexible RFID tag, the surgical item managing method comprising the steps of:

obtaining a tag position of the flexible RFID tag;

taking an image of a patient, so as to obtain an image position of the patient;

determining whether a position of the flexible RFID tag and the image position of the patient overlap, so as to determine whether the surgical item corresponding to the flexible RFID tag is in the patient's body; and

giving a warning if the surgical item is in the patient's body.

2. The surgical item managing method for a smart operating room according to claim 1 , wherein the surgical item managing system for the smart operating room further comprises a scanner, and the scanner comprises a plurality of read regions, wherein the step of obtaining the tag position of the flexible RFID tag further comprises: scanning the flexible RFID tag with the scanner and receiving a plurality of return signals from the flexible RFID tag by the plurality of read regions.

3. The surgical item managing method for a smart operating room according to claim 2 , wherein the step of obtaining the tag position of the flexible RFID tag further comprises: computing the tag position of the flexible RFID tag according to levels of signal strength of the return signals received by the read regions.

4. The surgical item managing method for a smart operating room according to claim 3 , wherein the read region which receives the return signals with the highest level of signal strength is nearest to the flexible RFID tag.

5. The surgical item managing method for a smart operating room according to claim 4 , further comprising: transmitting data about the position of the flexible RFID tag to an external computer.

6. The surgical item managing method for a smart operating room according to claim 5 , further comprising: recording in a blockchain network a transportation history carried by the flexible RFID tag.

7. A surgical item managing system for a smart operating room, the surgical item managing system being adapted to manage a surgical item used during a surgical procedure, the surgical item comprising a flexible RFID tag, the surgical item managing system comprising:

a scanner for scanning the flexible RFID tag, so as to obtain a tag position of the flexible RFID tag;

a video recording module for taking an image of a patient, so as to obtain an image position of the patient;

a processing module in signal connection with the scanner and the video recording module and adapted to obtain a position of the flexible RFID tag according to a data which the scanner acquires by scanning the flexible RFID tag and determine whether a position of the flexible RFID tag and the image position of the patient overlap, so as to determine whether the surgical item corresponding to the flexible RFID tag is in the patient's body; and

a warning module in signal connection with the processing module and adapted to generate a warning signal when the processing module confirms presence of the surgical item in the patient's body.

8. The surgical item managing system for a smart operating room according to claim 7 , wherein the scanner comprises a plurality of read regions for receiving a plurality of return signals from the flexible RFID tag.

9. The surgical item managing system for a smart operating room according to claim 8 , wherein the processing module computes the tag position of the flexible RFID tag according to levels of signal strength of the return signals received by the read regions.

10. The surgical item managing system for a smart operating room according to claim 9 , wherein the read region which receives the return signals with the highest level of signal strength is nearest to the flexible RFID tag.

11. The surgical item managing system for a smart operating room according to claim 10 , further comprising a network module in signal connection with the scanner and adapted to transmit to an external computer a data about the position of the flexible RFID tag.

12. The surgical item managing system for a smart operating room according to claim 11 , further comprising a blockchain tracking module in signal connection with the scanner and adapted to record in a blockchain network a transportation history carried by the flexible RFID tag.
