Systems and methods for defining and modifying range of motion of probe used in patient treatment

1. A system for treating or imaging tissue of a patient, said system comprising:

a probe sized for insertion into the patient;

a robotic arm configured to couple to the probe;

one or more computing devices operatively coupled to the robotic arm and configured with instructions for:

executing a training mode in response to a request from an operator of the system, wherein the training mode comprises the operator demonstrating an allowable range of motion of a distal end of the probe with the distal end of the probe inserted into a body of the patient;

exiting the training mode; and

treating or imaging the tissue of the patient with the probe after insertion of the distal end of the probe into the body of the patient, wherein the

robotic arm is caused to affect movement of the distal end of the probe within the body of the patient only within the allowable range of motion for the distal end of the probe.

2. The system of claim 1 , wherein prior to executing the training mode, the system defines an initial range of motion for the distal end of the probe by defining a region within which the distal end of the probe is confined to move.

3. The system of claim 2 , wherein the region is defined by a mathematical representation of the region.

4. The system of claim 2 , wherein the region is defined by an image of the region, the image including dimensions of the probe and a possible angular movement of the distal end of the probe.

5. The system of claim 1 , wherein the probe is an imaging probe and the system further comprises a treatment probe sized for insertion into the patient.

6. The system of claim 5 , wherein the training mode comprises the operator manipulating one or both of the imaging probe or treatment probe to define a limit on the allowable range of motion of the distal end of said one or both of the imaging probe or the treatment probe.

7. The system of claim 6 , wherein the training mode is conducted when both probes are inside of the patient.

8. The system of claim 7 , wherein the instructions further cause the system to operate the imaging probe to obtain an image of the treatment probe, and in response to the image, constrain the allowable range of motion of the distal end of the treatment probe.

9. The system of claim 7 , wherein the instructions further cause the system to operate the imaging probe to obtain an image of the treatment probe, and in response to the image, constrain the allowable range of motion of the distal end of the imaging probe.

10. The system of claim 9 , wherein the instructions further cause the system to operate the imaging probe to obtain an image of the treatment probe, and in response to the image, automatically move the distal end of the imaging probe within a predetermined area to avoid collision with the treatment probe.

11. The system of claim 7 , wherein the instructions further cause the system to operate the imaging probe to obtain an image of the patient's anatomy, and in response to the image, modifying the allowable range of motion of the distal end of the imaging probe.

12. The system of claim 11 , wherein the instructions further cause the system to process the image of the patient's anatomy using an image recognition application to identify an organ or region of tissue of the patient.

13. The system of claim 1 , wherein the instructions further cause the system to compare the allowable range of motion to a scan of the patient showing an area of the patient's anatomy near a treatment site and in response modify the allowable range of motion of the distal end of the probe in a region around the treatment site.

14. A method of treating target tissue at a target site of a patient, said method comprising:

manually inserting a distal end of a probe into the patient;

coupling the probe to a robotic arm;

executing a training mode, wherein the training mode comprises an operator defining an allowable range of motion of a distal end of the probe;

exiting the training mode; and

treating or imaging the target tissue of the patient with the probe after insertion of the distal end of the probe into a body of the patient, wherein

the robotic arm under control of one or more computing devices operably coupled with the probe is caused to affect movement of the distal end of the probe within the allowable range of motion for the distal end of the probe.

15. The method of claim 14 , wherein prior to executing the training mode, a system defines an initial range of motion for the distal end of the probe by defining a region within which the distal end of the probe is confined to move.

16. The method of claim 15 , wherein the region is defined by a mathematical representation of the region.

17. The method of claim 15 , wherein the region is defined by an image of the region, the image including dimensions of the probe and a possible angular movement of the distal end of the probe.

18. The method of claim 14 , wherein the probe is an imaging probe and the system further comprises a treatment probe sized for insertion into the patient.

19. The method of claim 18 , wherein the training mode comprises the operator manipulating one or both of the imaging probe or the treatment probe to define the allowable range of motion of the distal end of said one or both of the imaging probe or the treatment probe.

20. The method of claim 14 , further comprising comparing the allowable range of motion to a scan of the patient showing an area of the patient's anatomy near a treatment site and in response modifying the allowable range of motion of the distal end of the probe in a region around the treatment site.
