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 method of performing an orthopedic surgical procedure, the method comprising:

introducing a surgical instrument configured for use in surgically preparing a patient'"'"'s bone to receive a medical implant configured for implantation in the patient'"'"'s body into a medical device communications network, wherein introducing the surgical instrument into the medical device communications network includes wirelessly connecting a first wireless communication circuit mounted on the surgical instrument to the medical device communications network,

introducing the medical implant into the medical device communications network, wherein introducing the medical implant into the medical device communications network includes wirelessly connecting a second wireless communication circuit mounted on the medical implant to the medical device communications network,

monitoring a status of a human perceptible indicator operable to change in response to at least one of the surgical instrument and the medical implant being introduced out of sequence relative to a predetermined usage sequence, and

removing at least one of the surgical instrument and the medical implant in response to the status of the human perceptible indicator changing,

wherein the human perceptible indicator is one of a visual indicator and an audible indicator.

2. The method of claim 1, further comprising:

introducing a second medical implant configured for implantation in the patient'"'"'s body into the medical device communications network.

3. The method of claim 1, further comprising introducing a second surgical instrument configured for use in surgically preparing the patient'"'"'s bone to receive the medical implant into the medical device communications network.

4. A method of performing an orthopedic surgical procedure, the method comprising:

introducing a surgical instrument configured for use in surgically preparing a patient'"'"'s bone to receive a medical implant configured for implantation in the patient'"'"'s body into a medical device communications network, wherein introducing the surgical instrument into the medical device communications network includes wirelessly connecting a first wireless communication circuit mounted on the surgical instrument to the medical device communications network,

introducing the medical implant into the medical device communications network, wherein introducing the medical implant into the medical device communications network includes wirelessly connecting a second wireless communication circuit mounted on the medical implant to the medical device communications network,

monitoring a status of a human perceptible indicator operable to change in response to the surgical instrument and the medical implant being incompatible with each other, and

removing at least one of the surgical instrument and the medical implant in response to the status of the human perceptible indicator changing,

wherein the human perceptible indicator is one of a visual indicator and an audible indicator.

5. The method of claim 4, further comprising introducing a second medical implant configured for implantation in the patient'"'"'s body into the medical device communications network.

6. The method of claim 4, further comprising introducing a second surgical instrument configured for use in surgically preparing the patient'"'"'s bone to receive the medical implant into the medical device communications network.

7. A method of performing an orthopedic surgical procedure, the method comprising:

wirelessly connecting a first wireless communication circuit to a medical device communications network, the first wireless communication circuit being coupled to at least one of (i) a first surgical instrument configured for use in surgically preparing a patient'"'"'s bone to receive a medical implant, and (ii) a first medical implant configured for implantation in the patient'"'"'s body,

monitoring a status of a human perceptible indicator operable to change in response to at least one of the first surgical instrument and the first medical implant being incompatible or out sequence, according to a predetermined usage sequence, with at least one of a second surgical instrument and a second medical implant, and

removing at least one of the first surgical instrument and the first medical implant in response to the status of the human perceptible indicator changing,

wherein a second wireless communication circuit coupled to the at least one of the second surgical instrument and the second medical implant is wirelessly connected to the medical device communications network prior to wirelessly connecting the at least one of the first surgical instrument and the first medical implant to the medical device communications network, and

wherein the human perceptible indicator is one of a visual indicator and an audible indicator.

8. The method of claim 7, further comprising introducing at least one of a third surgical instrument and a third medical implant into the medical device communications network.
