Abstract

Disclosed is a system and method for enabling user preview and control of the size and shape of an electromagnetic energy field used in a surgical procedure. The disclosed system includes a selectively activatable source of microwave surgical energy in the range of about 900 mHz to about 5 gHz in operable communication with a graphical user interface and a database. The database is populated with data corresponding to the various surgical probes, such as microwave ablation antenna probes, that may include a probe identifier, the probe diameter, operational frequency of the probe, ablation length of the probe, ablation diameter of the probe, a temporal coefficient, a shape metric, and the like. The probe data is graphically presented on the graphical user interface where the surgeon may interactively view and select an appropriate surgical probe. Three-dimensional views of the probe(s) may be presented allowing the surgeon to interactively rotate the displayed image.

First claim

What is claimed is:

1. An ablation generator comprising:
a generator module configured to couple to at least one of a plurality of ablation probes, the generator module configured to generate ablative energy;
a display configured to display a user interface, the user interface configured to receive a user-selectable ablation shape and at least one probe parameter; and
a processor configured to:
select at least one of the plurality of ablation probes suitable for forming an ablation volume corresponding to the user-selectable ablation shape based on the at least one probe parameter; and
signal the display to preview at least one selected ablation probe.

2. The generator according to claim 1 , further comprising:
a storage device coupled to the processor and configured to store a database of a plurality of probe parameters.

3. The generator according to claim 2 , further comprising:
a data interface coupled to the storage device, the data interface configured to couple to an external device storing an updated plurality of probe parameters.

4. The generator according to claim 3 , wherein the data interface is further configured to synchronize the database with the updated plurality of probe parameters.

5. The generator according to claim 1 , wherein the at least one probe parameter is selected from the group consisting of a probe diameter, a frequency, an ablation dimension, and a temporal coefficient.

6. The generator according to claim 2 , wherein the user interface includes a rotation user interface element configured to rotate the user-selectable ablation shape.

7. The generator according to claim 1 , wherein the user interface includes a temporal user interface element configured to display an animated depiction of the user-selectable ablation shape.

8. The generator according to claim 7 , wherein the temporal user interface element includes a user-adjustable slider corresponding to a time scale of the animated depiction.

9. A method for planning an ablation procedure, the method comprising:
displaying a user interface configured to receive a user-selectable ablation shape and at least one probe parameter;
selecting at least one of a plurality of ablation probes suitable for forming an ablation volume corresponding to the user-selectable ablation shape based on the at least one probe parameter; and
displaying a preview of the at least one selected ablation probe.

10. The method according to claim 9 , further comprising:
storing a database of a plurality of probe parameters in a storage device.

11. The method according to claim 10 , further comprising:
coupling an external device storing an updated plurality of probe parameters to a data interface coupled to the storage device.

12. The method according to claim 11 , wherein coupling the external device further includes automatically synchronizing the database with the updated plurality of probe parameters.

13. The method according to claim 9 , wherein the at least on probe parameter is selected from the group consisting of a probe diameter, a frequency, an ablation dimension, and a temporal coefficient.

14. The method according to claim 9 , wherein displaying the user interface further includes displaying a rotation user interface element configured to rotate the user-selectable ablation shape.

15. The method according to claim 9 , wherein displaying the user interface further includes displaying a temporal user interface element configured to display an animated depiction of the user-selectable ablation shape.

16. The method according to claim 15 , wherein displaying the temporal user interface element further includes displaying a user-adjustable slider corresponding to a time scale of the animated depiction.
