A medical method, comprising: scanning a parent radio frequency identification (RFID) tag attached to a surgical device carrying apparatus seating a plurality of surgical devices, the parent RFID tag uniquely identifying the surgical device carrying apparatus and allowing unique identification of each of the plurality of surgical devices seated in the surgical device carrying apparatus, each of the surgical devices being seated in one of a plurality of recesses in the surgical device carrying apparatus, each of the plurality of recesses being covered by one of a plurality of lids removably attached to the surgical device carrying apparatus and configured to prevent removal of the one of the plurality of surgical devices from the surgical device carrying apparatus until removed from the surgical device carrying apparatus; scanning a plurality of child RFID tags, each of the child RFID tags uniquely identifying one of the plurality of surgical devices, and each of the plurality of child RFID tags being attached to one of the plurality of lids; after scanning the parent RFID tag and the plurality of child RFID tags, sterilizing the surgical device carrying apparatus having the parent RFID tag attached thereto and having the plurality of surgical devices seated therein; after sterilizing the surgical device carrying apparatus, detaching at least one of the plurality of lids from the surgical device carrying apparatus to allow at least one of the plurality of surgical devices to be removed from the surgical device carrying apparatus and discarding the at least one lid; after detaching and discarding the at least one lid, removing the at least one surgical device for use in a surgical procedure; after removing and using the at least one surgical device, rescanning the parent RFID tag attached to the surgical device carrying apparatus; and based at least in part on the rescanning of the parent RFID tag, determining which of the plurality of surgical devices remain seated in the surgical device carrying apparatus; after determining which of the plurality of surgical devices remain seated in the surgical device carrying apparatus, restocking the surgical device carrying apparatus to replace the at least one surgical device no longer seated in the surgical device carrying apparatus and the at least one lid no longer attached to the surgical device carrying apparatus, each of the restocked lids having attached thereto a child RFID tag uniquely identifying the restocked surgical device seated in one of the plurality of recesses covered by the restocked lid; and causing the parent RFID tag to allow unique identification of each of the one or more restocked surgical devices. scanning a parent radio frequency identification (RFID) tag attached to a surgical device carrying apparatus seating a plurality of surgical devices, the parent RFID tag uniquely identifying the surgical device carrying apparatus and allowing unique identification of each of the plurality of surgical devices seated in the surgical device carrying apparatus, each of the surgical devices being seated in one of a plurality of recesses in the surgical device carrying apparatus, each of the plurality of recesses being covered by one of a plurality of lids removably attached to the surgical device carrying apparatus and configured to prevent removal of the one of the plurality of surgical devices from the surgical device carrying apparatus until removed from the surgical device carrying apparatus;
