Abstract

Certain embodiments of the present invention provide n system for orienting a surgical tool with respect to a patient including: a tool guide for facilitating orientation of the surgical tool with respect to the patient, the tool guide including a mounting portion and a tool receiving portion, wherein the tool guide is capable of being integrated with at least a portion of a radiological imaging subsystem including an adjustably moveable mounting structure. In an embodiment, the tool receiving portion is capable of receiving an end-effector. In an embodiment the at least a portion of the radiological imaging subsystem comprises a C-arm. In an embodiment the radiological imaging subsystem comprises a fluoroscopic imaging subsystem. In an embodiment, the end-effector comprises at least one of: an aperture, a cutting device, a drilling device, a clamp, a sleeve, a mounting surface, a ring, a rail, a threaded shaft, a clasp, a bayonet mount, an imaging device, an ultrasound probe, a surgical tool, a catheter, a pin, a screw, a plate, a drill, an awl, and a probe. In an embodiment, the tool guide further comprises an end-effector. In an embodiment, a position of the surgical tool is capable of being adjusted by automatically moving the adjustably movable mounting structure. In an embodiment, the system further comprises at least one position sensing subsystem for ascertaining a position of the surgical tool with respect to the patient.

Claims

1. A system for orienting a surgical tool with respect to a patient comprising:

a tool guide for facilitating orientation of the surgical tool with respect to the patient, said tool guide comprising a mounting portion and a tool receiving portion,

wherein said tool guide is capable of being integrated with at least a portion of a radiological imaging subsystem comprising an adjustably moveable mounting structure.

2. The system of claim 1, wherein said tool receiving portion is capable of receiving an end-effector.

3. The system of claim 1, wherein said at least a portion of said radiological imaging subsystem comprises a C-arm.

4. The system of claim 1, wherein said radiological imaging subsystem comprises a fluoroscopic imaging subsystem.

5. The system of claim 2, wherein said end-effector comprises at least one of:

an aperture, a cutting device, a drilling device, a clamp, a sleeve, a mounting surface, a ring, a rail, a threaded shaft, a clasp, a bayonet mount, an imaging device, an ultrasound probe, a surgical tool, a catheter, a pin, a screw, a plate, a drill, an awl, and a probe.

6. The system of claim 1, wherein said tool guide further comprises an end-effector.

7. The system of claim 1, wherein a position of the surgical tool is capable of being adjusted by automatically moving said adjustably movable mounting structure.

8. The system of claim 1 further comprising at least one position sensing subsystem for ascertaining a position of the surgical tool with respect to the patient.

9. The system of claim 8, wherein said adjustably moveable mounting structure is capable of being automatically moved based at least on said position of the surgical tool with respect to the patient.

10. The system of claim 1, wherein said at least one sensor comprises at least one of:

an image registration subsystem;

an imaging subsystem;

an optical navigational subsystem; and

an electromagnetic navigational subsystem.

11. The system of claim 1 further comprising an integration mechanism mounted to said adjustably moveable mounting structure for releasably integrating said tool guide to said adjustably moveable mounting structure.

12. A method for orienting a surgical tool with respect to a patient comprising:

integrating a tool guide with at least a portion of a radiological imaging subsystem, said tool guide capable of receiving the surgical tool; and

adjusting a position of said at least a portion of said radiological imaging subsystem, wherein a position of the surgical tool is adjusted with respect to the patient.

13. The method of claim 12 further comprising tracking said position of the surgical tool with respect to the patient to form a tracked position.

14. The method of claim 13, wherein said adjusting said position of said adjustably moveable mounting structure is automatically performed based at least in part on said tracked position.

15. The method of claim 12 further comprising adjusting a position of an end-effector on said tool guide.

16. The method of claim 12, wherein said adjusting said position of said adjustably moveable mounting structure is performed according to a planned trajectory of the surgical tool with respect to the patient.

17. The method of claim 12, wherein said integrating a tool guide with said adjustably moveable mounting structure is performable with an integration mechanism for releasably integrating said tool guide with said adjustably moveable mounting structure.

18. A method for orienting a surgical tool with respect to a patient comprising:

engaging the surgical tool with a tool guide, said tool guide integrated with an adjustably moveable mounting structure;

positioning a position of the surgical tool with respect to the patient;

ascertaining a tracked position of the surgical tool with respect to the patient; and

determining whether said tracked position of the surgical tool with respect to the patient corresponds to a desired position of the surgical tool with respect to the patient.

19. The method of claim 18 further comprising adjusting a position of said adjustably moveable mounting structure to cause a corresponding adjustment in said position of the surgical tool with respect to the patient in response to determining whether said tracked position of the surgical tool with respect to the patient corresponds to said desired position of the surgical tool with respect to the patient.

20. The method of claim 19, wherein said adjusting said position of the surgical tool is performed automatically.

21. The method of claim 18, wherein said desired position of the surgical tool with respect to the patient is based at least in part on a surgical navigation plan.

22. A system for orienting a surgical tool with respect to a patient comprising:

a tool guide for facilitating orientation of the surgical tool with respect to the patient, said tool guide comprising a mounting portion and a tool receiving portion,

wherein said tool guide is capable of being integrated with at least a portion of an image intensifier subsystem comprising an adjustably moveable mounting structure.

23. A system for orienting a surgical tool with respect to a patient comprising:

a tool guide for facilitating orientation of the surgical tool with respect to the patient, said tool guide comprising a mounting portion and a tool receiving portion,

wherein said tool guide is capable of being integrated with at least a portion of a navigation subsystem comprising an adjustably moveable mounting structure.

24. A system for orienting a surgical tool with respect to a patient comprising:

a tool guide for facilitating orientation of the surgical tool with respect to the patient, said tool guide comprising a mounting portion and a tool receiving portion,

wherein said tool guide is capable of being integrated with at least a portion of an aiming subsystem comprising an adjustably moveable mounting structure.
