Abstract

A medical device communications network comprises a plurality of medical devices including either or both of a first number of surgical instruments and a second number of implants configured for subcutaneous implantation in a biological body. A corresponding plurality of wireless communication circuits are each mounted to a different one of the plurality of medical devices. Each of the plurality of wireless communication circuits is configured to broadcast medical device information relating to the medical device to which it is mounted and to receive information relating to any other of the plurality of medical devices. The network may or may not include a master wireless communications circuit configured to receive the medical device information broadcast by any of the plurality of slave wireless communication circuits and to broadcast the information relating to any other of the plurality of medical devices.

Claims

1. A medical device communications network, comprising:

a first surgical instrument configured for use in surgically preparing a patient'"'"'s bone to receive a surgical implant,

a first wireless communication circuit mounted to the first surgical instrument, the first wireless communication circuit having a first wireless transceiver electrically connected to at least one of a first visual indicator and a first audible indicator, and

a processor-readable, non-transitory storage memory having processor-executable instructions stored thereon, which, when executed by a processor, cause the first wireless transceiver to;

receive information broadcasted from one or more other surgical instruments used during a surgical procedure,

determine whether the first surgical instrument is being used out of order relative to a predetermined surgical instrument usage sequence,

determine whether the first surgical instrument is incompatible with another surgical instrument used during the surgical procedure, and

activate at least one of the first visual indicator and the first audible indicator in response to determining that the first surgical instrument is one or more of being used out of order relative to the predetermined surgical instrument usage sequence or incompatible with any other surgical instrument used during the surgical procedure.

2. The medical device communications network of claim 1, further comprising:

a second surgical instrument configured for use in surgically preparing the patient'"'"'s bone to receive a surgical implant,

a second wireless communication circuit mounted to the second surgical instrument, the second wireless communication circuit having a second wireless transceiver electrically connected to at least one of a second visual indicator and a second audible indicator, and

instructions stored on the processor-readable, non-transitory storage memory, which, when executed by the processor, cause the second wireless transceiver to;

receive information broadcasted from the first surgical instrument or any other surgical instrument used during the surgical procedure,

determine whether the second surgical instrument is being used out of order relative to the predetermined surgical instrument usage sequence,

determine whether the second surgical instrument is incompatible with the first surgical instrument or any other surgical instrument used during the surgical procedure, and

activate at least one of the second visual indicator and second first audible indicator in response to determining that the second surgical instrument is one or more of;

(i) being used out of order relative to the predetermined surgical instrument usage sequence or (ii) incompatible with the first surgical instrument or any other surgical instrument used during the surgical procedure.

3. The medical device communications network of claim 2, further comprising:

instructions stored on the processor-readable non-transitory storage memory, which, when executed by the processor, cause the second wireless transceiver to broadcast information associated with the second surgical instrument to the first surgical instrument or any other surgical instrument used during the surgical procedure, the information associated with the second surgical instrument comprises at least a second device identification code, and

instructions stored on the processor-readable non-transitory storage memory, which, when executed by the processor, cause the first wireless transceiver to;

broadcast information associated with the first surgical instrument to the second surgical instrument or any other surgical instrument used during the surgical procedure, the information associated with the first surgical instrument comprises at least a first device identification code,

determine whether the first surgical instrument is being used out of order relative to the predetermined surgical instrument usage sequence based on the first device identification code and the second device identification code,

determine whether the first surgical instrument is incompatible with the second surgical instrument based on the first device identification code and the second device identification code, and

activate at least one of the first visual indicator and the first audible indicator in response to determining that the first surgical instrument is one or more of;

(i) being used out of order relative to the predetermined surgical instrument usage sequence or (ii) incompatible with the second surgical instrument based on the first device identification code and the second device identification code.
