The present invention concerns a read system (4), and the use of the latter, which is intended to communicate with a transponder (2) placed on a surgical instrument so as to quickly identify the surgical instrument by bringing the read system (4) close to the transponder (2) of the surgical instrument and then reading the information associated with the instrument contained in the transponder (2), and communication with a computer system (5), wherein the transponder (2) is housed in a compartment (13), formed in the instrument, said compartment (13) being closed off in a sealed manner by a thin lid (14) welded or affixed (3) to the body (10) of the surgical instrument so that the outer surface of the surgical instrument has no projecting sharp points, and with the transponder (2) communicating or recording, via the read system (4), information concerning clinical history.
