Abstract

A method serves to facilitate communication between members of an operating team in an operating room. Among others the method supports operation of different devices and expression of different command by gazing at a proper area on the monitor.

Claims

1. A method of monitoring and controlling a medical procedure comprising:

displaying on at least one monitor at least one image of at least one treatment area including tissue to be manipulated and a treatment tool;

tracking a plurality of team members using tracking devices having a field of view characterized by a viewing box with at least two team member tracking device viewing boxes having at least partially overlapping area (volume), each tracking device configured to track at least one uniquely identified team member;

defining at least one identifier associated with each team member;

communicating to each team member tracking device at least one unique team member identifying characteristic; and

when a physical location (or activity) of a first team member changes relative to a physical location (or activity) of a second team member, passing on by a tracking device originally associated with the first team member the first team member identifier and the first team member monitoring to a second (partially overlapping) team member tracking device.

2. The method according to claim 1, wherein the team member identifier is one of a group of identifiers consisting of anatomical characteristics of the team member, pressure developed by at least one limb of the team member, and an artificially generated identifier.

3. The method according to claim 2, wherein the anatomical characteristics of the team member comprise at least one of facial outline, distance between eyes, skin hue, voice and fingerprint.

4. The method according to claim 2, wherein the pressure developed by at least one limb of the team member is pressure developed by one of a foot and a palm of the team member.

5. The method according to claim 4, comprising measuring the pressure developed by at least one limb of the team member.

6. The method according to claim 2, wherein the artificially generated identifier is one of an RFID tag and a radiation counting tag attached to the team member.

7. The method according to claim 1 wherein the team member identifier includes data on team member hierarchy, team member functionality, and team member authorizations.

8. The method according to claim 1, further comprising emergency overriding limitations associated with team member identifier preferences/authorizations/hierarchy.

9. The method according to claim 1, further comprising passing on the team member identifier and team member monitoring to a corresponding team member tracking device with partially overlapping field of view of viewing box when at least 75% of the view boxes field of view overlap.

10. The method according to claim 1, further comprising deactivating a first operating team member tracking device and activating a second team member tracking device in order to avoid infrared radiation interference, when the first operating team member tracking device passes on the first team member identifier and monitoring to the second team member tracking device.

11. The method according to claim 1, further comprising distinguishing by at least one of the tracking devices between different team members and providing location coordinates of a uniquely identified team member to another tracking device.

12. The method according to claim 11, said providing by the first tracking device, location coordinates of a uniquely identified team member to a corresponding designated tracking device is in accordance with a predetermined team member hierarchy.

13. The method according to claim 1, wherein said passing on the first team member identifier and team member monitoring to a corresponding second team member tracking device with partially overlapping viewing box is done when the probability of the team member identification by the second team member tracking device is at least 75%.

14. The method according to claim 13, wherein the probability of the team member identification is based on an arithmetical average of at least 20 last team members identifications.

15. The method according to claim 1, wherein at least one team member tracking device is a master tracking device, further comprising tracking simultaneously a plurality of the team members by said master tracking device.

16. The method according to claim 1, wherein at least one of said at least one monitor configured to display at least one image of at least one treatment area including tissue to be manipulated and a treatment tool, is responsive to team member gaze.

17. The method according to claim 16, further comprising activating at least one of a group of system processes consisting of treatment area and a treatment tool on screen position, tool advancement, tool selection, tool configuration, and instructions to other team members, by the monitor responsive to team member gaze.

18. The method according to claim 16, further comprising communicating by the monitor responsive to the team member gaze with the treatment recipient support and conveying to the support commands to translate horizontally, translate vertically and tilt to hone in on coordinates provided by the tracking device.

19. The method according to claim 16, further comprising selecting the tool by tracking point of gaze on screen.

20. The method according to claim 16, further comprising executing instructions to other team members by tracking point of gaze on screen.
