A surgical instrument which comprises an instrument body (1) and an encapsulated electronic device (2) is provided, wherein the instrument body (1) is partially or completely made of a metal material; the encapsulated electronic device (2) comprises a radio frequency identification chip (21) which is electrically connected with the instrument body (1); the instrument body (1), which serves as an antenna of the radio frequency identification chip (21), is configured to acquire the electromagnetic wave energy so as to activate the radio frequency identification chip (21). According to the surgical instrument, the instrument body (1), which serves as the antenna of the encapsulated electronic device (2), is configured to acquire the electromagnetic wave energy so as to activate the radio frequency identification chip (21), so that no antenna is needed to be configured in the encapsulated electronic device (2), and thus the encapsulated electronic device (2) cannot affect operations of medical staff due to small size and can achieve excellent reading effect. |
