US 9,277,969 B2 · Microwave ablation system with user-controlled ablation size and method of use

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.

Dependent claims

An electromagnetic surgical ablation system, comprising:

a generator module configured to provide radiofrequency surgical energy;
a processor operably coupled to the generator module and programmed to respond to a shape selection user input corresponding to an antenna probe ablation pattern, wherein the processor causes a probe image corresponding to the antenna probe ablation pattern to be transmitted to a user interface operably coupled to the processor, the user interface is configured to:
display a probe image received from the processor;
receive the shape selection user input corresponding to an antenna probe ablation pattern;
and
display a rotated view of the antenna probe ablation pattern in response to rotational input;
a database in operable communication with the processor and adapted to store a wireframe model corresponding to at least one antenna probe ablation pattern;
and
a temporal user interface element configured to display on the user interface an animated depiction over a time scale of the antenna probe ablation pattern.
