Abstract
Electrosurgical generators having improved functionality and a user interface. In an example, the user may modify therapy output parameters without interrupting therapy delivery within a therapy regimen by accessing a change tool on the user interface, with the change tool operable to change a stack selector configuration. In an example, the display shows both therapy amplitudes and encountered impedances for a plurality of therapy pulses in different portions of a display.
Claims13
An electrosurgical generator comprising:
- at least two contacts for coupling to one or more electrosurgical probes;
- a high voltage power source comprising at least first and second capacitors configured for outputting therapy pulses;
- a delivery circuit comprising a plurality of switches configured to route an output from the power source to selected ones of the at least two contacts, the delivery circuit comprising a stack selector;
- a controller having stored instructions that can be selected, configured or adjusted by a user, the stored instructions including at least one instruction set for delivering a therapy regimen, the therapy regimen comprising a plurality of pulses each having a pulse amplitude and a pulse width, the instruction set defining the pulse amplitude and the pulse width;
- and
- a user interface having a user operable change tool that the user can actuate during execution of the therapy regimen to modify the pulse amplitude without stopping or interrupting the therapy regimen;
- wherein the stack selector comprises a plurality of switches and has each of a first configuration in which all of the capacitors are used for purposes of outputting therapy pulses, and a second configuration in which less than all of the capacitors are used for purposes of outputting therapy pulses;
- and
- further wherein controller is configured to switch the stack selector between the first configuration and the second configuration in response to actuation of the change tool by a user during execution of the therapy regimen.
A method of operating an electrosurgical generator, the electrosurgical generator having at least two contacts for coupling to one or more electrosurgical probes, a high voltage power source comprising at least first and second capacitors configured for outputting therapy pulses, a delivery circuit comprising a plurality of switches configured to route an output from the power source to selected ones of the at least two contacts, a controller having stored instructions that can be selected, configured or adjusted by a user, the stored instructions including at least one instruction set for delivering a therapy regimen, the therapy regimen comprising a plurality of pulses each having a pulse amplitude and a pulse width, the instruction set defining the pulse amplitude and the pulse width, and a user interface;
- the method comprising:
- receiving an indication to start the therapy regimen;
- displaying, on the user interface, a user operable change tool, the user operable change tool configured to be responsive to user actuation during execution of the therapy regimen to modify the pulse amplitude without stopping or interrupting the therapy regimen, wherein the delivery circuit includes a stack selector, the stack selector having a plurality of switches and each of a first configuration in which all of the capacitors are used for purposes of outputting therapy pulses, and a second configuration in which less than all of the capacitors are used for purposes of outputting therapy pulses, the stack selector responsive to the user operable change tool;
- with the user operable change tool accessible on the user interface, initiating the therapy regimen using a first therapy amplitude by setting the stack selector to the first configuration;
- receiving, at the user interface, an actuation of the user operable change tool;
- and
- continuing the therapy regimen using a second therapy amplitude, without stopping or interrupting the therapy regimen, by setting the stack selector to the second configuration.
