Abstract

A method and apparatus for managing the establishment of a wireless connection between an instrument host and a non-fixed device is provided. The method comprises acquiring the non-fixed medical device address over a fixed wire by replacing the traditional wireless searching mechanism. The method also comprises providing an authentication mechanism between the instrument host and the non-fixed device, for example, across a wireless communications network.

Claims

1. A method for establishing a wireless connection between an instrument host and at least one non-fixed medical device, comprising:

providing a fixed cable wire connection between the instrument host and the non-fixed medical device, wherein the instrument host is a component of a phacoemulsification system, wherein the non-fixed medical device comprises a footpedal switch for use with the instrument host, and wherein the instrument host provides master device functionality and the non-fixed medical device provides slave device functionality;

discovering a slave device address of the non-fixed medical device over said fixed cable wire;

authenticating the non-fixed medical device; and

removing the fixed cable wire between the instrument host and the non-fixed medical device before authenticating the instrument host with the non-fixed medical devices, wherein the authenticating is performed over a wireless communications network.

2. The method of claim 1, further comprising managing the discovering and authenticating using a Bluetooth bonding utility.

3. The method of claim 2, wherein the providing further comprises:

reporting the absence of the fixed cable wire to the user via the Bluetooth bonding utility from a connection controller;

instructing the user, via the Bluetooth bonding utility, to attach the fixed cable wire when the fixed cable wire is reported as not present;

detecting the presence of the fixed cable wire by the connection controller; and

reporting the presence of the fixed cable wire to the user via the Bluetooth bonding utility from the connection controller.

4. The method of claim 1, further comprising storing the slave device address of the non-fixed medical device obtained over the fixed cable and making said address available to the slave device master device for use during authentication.

5. The method of claim 1, wherein discovering further comprises:

sending a query message over the fixed cable wire from the master device to the slave device requesting the slave device address;

replying to said query message by sending an inquiry response message over the fixed cable wire from the slave device to the master device wherein the slave device address is encapsulated in the inquiry response.

6. The method of claim 1, further comprising managing the discovering and authenticating using a Bluetooth bonding utility, and wherein removing the fixed cable wire further comprises:

instructing the user to disconnect the fixed cable wire when the Bluetooth bonding utility obtains the slave device address from the controller;

detecting the fixed cable wire is removed from the controller to the Bluetooth bonding utility; and

indicating to the user that the non-fixed medical device and instrument host are ready and available for authentication via the Bluetooth bonding utility.

7. The method of claim 1, wherein the wireless connection is a Bluetooth wireless connection.

8. A method for establishing a wireless connection between an instrument host and at least one non-fixed medical device, comprising:

providing a fixed cable wire connection between the instrument host and the non-fixed medical device, wherein the instrument host is a component of a phacoemulsification system, wherein the non-fixed medical device comprises a footpedal switch for use with the instrument host, and wherein the instrument host provides master device functionality and the non-fixed medical device provides slave device functionality;

discovering a slave device address of the non-fixed medical device over said fixed cable wire;

authenticating the non-fixed medical device;

removing the fixed cable wire between the instrument host and the non-fixed medical device before authenticating the instrument host with the non-fixed medical device, wherein the authenticating is performed over a wireless communications network; and

locking the fixed cable wire connection to prevent the non-fixed medical device from switching into a wired mode.

9. A connectivity management system, comprising:

an instrument host, comprising;

a bonding utility; and

a controller configured to control communications with at least one obtained slave device over a fixed wire;

a non-fixed medical device configured to support wired and wireless modes of operation, wherein the non-fixed medical device comprises a footpedal switch;

a fixed wire connecting the instrument host to the non-fixed medical device; and

a wireless communications network;

wherein the instrument host is a component of a phacoemulsification system and wherein the instrument host is configured to discover a slave device address of the non-fixed medical device over said fixed wire and authenticate the non-fixed medical device after removing the fixed wire between the instrument host and the non-fixed medical device, wherein the authentication is performed over a wireless communications network.

10. The system of claim 9, wherein the bonding utility comprises a graphical user interface for managing discovery and authentication.

11. The system of claim 9, wherein the instrument host controls and operates selected functionality of the non-fixed medical device.

12. The system of claim 9, wherein the controller comprises Bluetooth master device functionality capable of transmitting information to and receiving information from the non-fixed medical device.

13. The system of claim 9, wherein the non-fixed medical device comprises Bluetooth slave device functionality capable of transmitting information to and receiving information from the controller.

14. The system of claim 9, wherein the bonding utility is a Bluetooth bonding utility.

15. A method for providing Bluetooth communications between a non-fixed medical device and a controller, comprising:

acquiring a Bluetooth address of the non-fixed medical device over a fixed cable wire;

registering said non-fixed medical device Bluetooth address in a list of Bluetooth addresses maintained by said controller; and

authenticating said non-fixed medical device with said controller over a wireless communications network after removing the fixed cable wire between the controller and the non-fixed medical device,

wherein the controller is a component of a phacoemulsification system and wherein the non-fixed medical device comprises a footpedal switch.

16. The method of claim 15, wherein acquiring further comprises sending the Bluetooth address of the non-fixed medical device in response to queries from the controller.

17. The method of claim 15, wherein registering further comprises storing the non-fixed medical device Bluetooth address received over the fixed cable wire within the controller.
