Abstract

The present invention includes an apparatus and the method for remotely controlling an ablation beam for removal of material from a body so that it to impinge at various locations on the surface and can be remotely blocked or enabled, when monitored with a video camera to view the body surface in an isolated environment.

Claims

1. A method of controlling a ablation beam for ablation of a body surface, comprising:

positioning a video camera to view the body surface in an isolated environment whereby the body surface needs to be in an isolated environment because of contagious diseases, radiation, or special illumination control;

providing a remotely-controllable ablation beam that can be controlled to impinge at various locations on the surface and can be remotely blocked or enabled;

receiving a video signal from the video and displaying the signal on a video monitor; and

controlling the beam using a control module and the video monitor, wherein the control module and the video monitor are remote from the body surface.

2. The method of claim 1, wherein a surgeon uses a touch screen to control the ablation.

3. The method of claim 1, wherein the beam is controlled in position by an x-y table.

4. The method of claim 3, wherein the beam passes through a variable-focus lens on the x-y table and the variable-focus lens, and wherein the control module automatically adjusts the lens for changes in distance between the body surface and the table.

5. The method of claim 1, wherein the control module enables or blocks emission of the ablation beam based on colors of the target area, based on one or more preset emission specifications.

6. The method of claim 5, wherein the beam is amplified in an optically-pumped amplifier and the blocking is by shutting off the current to the amplifiers pump diodes or wherein the beam is amplified in a semiconductor optical amplifier and the blocking is by shutting off the current to the semiconductor optical amplifier.

7. The method of claim 5, wherein there is an over-ride switch that allows ablation to be enabled regardless of a blocking color specification.

8. The method of claim 1, wherein special illumination control is used and the measured color is either an IR color or a UV color.

9. The method of claim 1, wherein special illumination control is used and color contrast enhancing lighting is used.

10. The method of claim 1, wherein the wherein control module enables or blocks emission of the ablation beam based on colors of the target area and distance from a surface, based on preset emission specifications.

11. The method of claim 1, wherein the ablation-probe is mounted on a control-module-positionable table.

12. A method of controlling an ablation beam for ablation of a surface, comprising:

positioning at least one sensor to view the surface and sending a signal from the sensor to a remote control module;

providing a remotely-controllable ablation beam that can be controlled to impinge optical pulses ten picoseconds or less in duration at various locations on the surface; and

controlling location where the beam impinges the surface using a control module based on the signal received from the at least one sensor.

13. The method of claim 12, wherein control module enables or blocks emission of the ablation beam based on colors of the target area or distance from a surface, based on one or more preset emission specifications.

14. The method of claim 12, wherein the beam impingement is controlled by an x-y table.

15. The method of claim 14, wherein the x-y table also has a z-drive.

16. The method of claim 14, wherein the beam passes through a variable-focus lens on the x-y table and the variable-focus lens, and wherein the control module automatically adjusts the lens for changes in distance between the surface and the table.

17. The method of claim 12, wherein an operator uses a touch screen to control the ablation.

18. A method of controlling an ablation beam in the ablation of an object, comprising:

positioning at least one sensor to view the object;

providing a remotely-controllable ablation beam that can be controlled to impinge optical pulses of ten picoseconds or less in duration at various locations on the object; and

controlling the beam impingement using a control module that receives a signal from the at least one sensor, wherein the control module is remote from the object.

19. The method of claim 18, wherein the control module directs the ablation over a custom-shaped area.

20. The method of claim 18, wherein the control is remote for safety reasons.
