Abstract

The invention provides systems and method for the removal of diseased cells during surgery.

Claims (37)

1. A system comprising:

an excitation source that emits an excitation light towards an object including a plurality of cells;

an image processor that detects light from the object including the plurality of cells;

a treatment device that destroys one or more cells;

a feedback system that detects a condition of each cell of the plurality of cells to identify one or more diseased cells amongst the plurality of cells using the detected light, and wherein the feedback system targets the one or more diseased cells with the treatment device and applies a treatment using the treatment device to the one or more diseased cells to destroy the one or more diseased cells.

2. The system of claim 1 , wherein the feedback system individually targets the treatment device at each of the one or more diseased cells.

3. The system of claim 1 , wherein the treatment device leaves healthy cells surrounding the one or more diseased cells substantially untreated.

4. The system of claim 1 , wherein the detected diseased cells are cancer cell.

5. The system of claim 1 , wherein the detected diseased cells comprise at least one of a central nervous cell, a cardiac cell, a bone cell, a tendon cell, a muscle cell, a tumor associated cell.

6. The system of claim 1 , wherein the detected diseased cells comprise a mammal cell.

7. The system of claim 6 , wherein the detected diseased cells compromise a human cell.

8. The system of claim 1 , wherein the treatment device uses light energy.

9. The system of claim 8 , wherein the treatment device comprises a plurality of lights.

10. The system of claim 8 , wherein an optical fiber bundle collects and distributes light energy to the diseased cells.

11. The system of claim 10 , wherein the energy source comprises a laser that laser ablates the diseased cells.

12. The system of claim 1 , wherein the treatment device comprises a laser.

13. The system of claim 12 , further comprising an optical bundle that collects light from the laser and directs it towards the object.

14. The system of claim 12 , further comprising a laser guiding system that controls the laser, wherein the laser guiding system comprises one or more galvanometer mirrors, MEMS mirrors, acousto-optic deflectors, micromirror, acousto-optical modulators used as deflector, piezo-electrial mirrors, electro-optical deflector, polygonal mirror, or planar mirrors on a rotating shaft.

15. The system of claim 1 , wherein the treatment device comprises a Radio Frequency ablation device.

16. The system of claim 1 , wherein the treatment device comprises a cryo-ablation device.

17. The system of claim 1 , wherein the image processor has a field of view substantially greater than a diameter of a human cancer cell and an analysis resolution substantially matched to the diameter of the human cancer cell.

18. The system of claim 1 , wherein the feedback system:

(a) locates the one or more diseased cells within a field of view of the image processor;

(b) targets the locations of the one or more diseased cells with the treatment device;

(c) locates an actual treatment location from the treatment device within the field of view of the image processor; and

(d) controls movement of the treatment device based on the locations of the one or more diseased cells and the actual treatment location.

19. The system of claim 18 , wherein the feedback system post-images tissue treated with the treatment device and verifies that the one or more diseased cells have been treated.

20. The system of claim 1 , wherein the image processor detects diseased cells within 1 cm from a surface of the object.

21. The system of claim 20 , wherein the image processor detects light having a wavelength equal to or between 350 nm and 670 nm.

22. The system of claim 1 , further comprising a fluid reservoir that flushes a surface of the object with a fluid during treatment with the treatment device.

23. The system of claim 22 and, wherein a flow of the fluid is sufficient to at least one of flush debris from a surface of the object and prevent excess treatment of healthy tissue surrounding the one or more diseased cells by the treatment device.

24. The system of claim 1 , wherein the treatment device treats either an entire field of view of the image processor, or a predefined subsection of the field of view, in less than or equal to about 1 second.

25. The system of claim 1 , wherein the feedback system individually determines whether each cell of the object visible within a field of view of the image processor is a diseased cell.

26. The system of claim 1 , wherein the treatment device is pulsed with a pulse duration less than or equal to 100 ns.

27. The system of claim 1 , wherein the treatment device causes delayed cellular death.

28. The system of claim 1 , further comprising an optical receptor that receives the light from the object, and wherein the image processor detects the received light from the object.

29. The system of claim 1 , wherein the treatment device ablates tissue, and wherein an amount of tissue that is ablated from the object is controlled by a duration of exposure of the tissue to the treatment device.
