Abstract

A smart connector system includes a machine connector disposed on a face of a surgical machine, an illumination ring located on the face of the surgical machine and disposed around a periphery of the machine connector, an RFID reader antenna located in close proximity to the machine connector and the face of the surgical machine, and an accessory connector adapted to couple with the machine connector. The accessory connector has an RFID tag antenna and is capable of attaching a tool to the surgical machine. When the accessory connector is brought within close proximity to the machine connector, a communications connection is established between the RFID tag antenna and the RFID reader antenna.

Claims

1. A surgical machine, comprising:

a machine connector disposed on a face of the surgical machine;

an RFID reader antenna, located in close proximity to the machine connector, and configured to establish a communications connection between the surgical machine and a surgical tool, wherein the RFID reader antenna is configured to read an identification datum from an RFID tag antenna on the surgical tool, wherein the surgical machine is configured to determine if the surgical tool can safely be used with the surgical machine based on the identification datum; and

an illumination ring located on the face of the surgical machine at least partially on a periphery of the machine connector, wherein the surgical machine is configured to illuminate the illumination ring in different colors to indicate different modes of operation or statuses of the surgical machine;

wherein the surgical machine is configured to provide power to the surgical tool only if the determination is made that the surgical tool can safely be used with the surgical machine and wherein illuminating the illumination ring in different colors to indicate different modes of operation or statuses of the surgical machine comprises illuminating the illumination ring in a pattern or color indicative of the determination as to whether the surgical tool can safely be used with the surgical machine.

2. The surgical machine of claim 1 wherein in determining if the surgical tool can safely be used with the surgical machine, the surgical machine is configured to compare the identification datum with a set of data corresponding to different surgical tools.

3. The surgical machine of claim 1, wherein the machine connector is one of at least two machine connectors on the face of the surgical machine and wherein each of at least two of the machine connectors includes a separate illumination ring on a respective periphery of the machine connector.

4. The surgical machine of claim 3, wherein the separate illumination rings are configured to be separately illuminated in a color or pattern indicative of a mode of operation or status of the respective illumination ring'"'"'s machine connector.

5. The surgical machine of claim 1,

wherein the machine connector is mounted to a manifold located behind and attached to a front panel of the surgical machine;

wherein the surgical machine further comprises a printed circuit board (PCB) located between the manifold and the front panel such that the machine connector protrudes through the PCB and front panel.

6. The surgical machine of claim 5, further comprising light emitting diodes (LEDs) mounted on the PCB.

7. The surgical machine of claim 6, wherein the LEDs are mounted on a side of the PCB that does not face the front panel and wherein the PCB comprises holes that allow light from the LEDs to pass through the PCB.

8. The surgical machine of claim 6, wherein the illumination ring comprises a lens configured to diffuse and/or refract light from the LEDs.

9. The surgical machine of claim 1, wherein the surgical machine is an ophthalmic surgical machine and wherein the surgical tool a scissor, probe, laser, illuminator, or hand piece.

10. A surgical machine, comprising:

a machine connector disposed on a face of the surgical machine;

an RFID reader antenna, located in close proximity to the machine connector, and configured to establish a communications connection between the surgical machine and a surgical tool, wherein the RFID reader antenna is configured to read an identification datum and a use datum from an RFID tag antenna on the surgical tool, wherein the surgical machine is configured to determine if the surgical tool can safely be used with the surgical machine based on the identification datum and the use datum; and

an illumination ring located on the face of the surgical machine at least partially on a periphery of the machine connector, wherein the surgical machine is configured to illuminate the illumination ring in different colors to indicate different modes of operation or statuses of the surgical machine;

wherein the surgical machine is configured to disable the surgical tool if the determination is made that the surgical tool cannot safely be used with the surgical machine and wherein illuminating the illumination ring in different colors to indicate different modes of operation or statuses of the surgical machine comprises illuminating the illumination ring in a pattern or color indicative of the determination as to whether the surgical tool cannot safely be used with the surgical machine.

11. The surgical machine of claim 10 wherein in determining if the surgical tool can safely be used with the surgical machine, the surgical machine is configured to compare the identification datum with a first set of data corresponding to different surgical tools to ascertain which tool is connected to the surgical machine;

and

compare the use datum with a data point that indicates whether it is safe to use the tool.

12. The surgical machine of claim 10 wherein in determining if the surgical tool can safely be used with the surgical machine, the surgical machine is configured to compare the identification datum with a first set of data corresponding to different surgical tools to ascertain which tool is connected to the surgical machine;

and

compare the use datum with a data point that indicates a number of times the tool can be used safely.

13. The surgical machine of claim 10 wherein the use datum provides information about a problem with the surgical tool.

14. The surgical machine of claim 10, wherein the machine connector is one of at least two machine connectors on the face of the surgical machine and wherein each of at least two of the machine connectors includes a separate illumination ring on a respective periphery of the machine connector.

15. The surgical machine of claim 14, wherein the separate illumination rings are configured to be separately illuminated in a color or pattern indicative of a mode of operation or status of the respective illumination ring'"'"'s machine connector.

16. The surgical machine of claim 10,

wherein the machine connector is mounted to a manifold located behind and attached to a front panel of the surgical machine;

wherein the surgical machine further comprises a printed circuit board (PCB) located between the manifold and the front panel such that the machine connector protrudes through the PCB and front panel.

17. The surgical machine of claim 16, further comprising light emitting diodes (LEDs) mounted on the PCB.

18. The surgical machine of claim 17, wherein the LEDs are mounted on a side of the PCB that does not face the front panel and wherein the PCB comprises holes that allow light from the LEDs to pass through the PCB.

19. The surgical machine of claim 17, wherein the illumination ring comprises a lens configured to diffuse and/or refract light from the LEDs.

20. The surgical machine of claim 10, wherein the surgical machine is an ophthalmic surgical machine and wherein the surgical tool a scissor, probe, laser, illuminator, or hand piece.
