Methods and systems related to an electrosurgical controller

An electrosurgical controller comprising:

• a processor;
• a memory coupled to the processor;
• a voltage generator operatively coupled to the processor, the voltage generator comprising an active terminal also coupled to the processor;
• the memory configured to store a program that, when executed by the processor, is configured to cause the processor to:
• command delivery of energy to the active terminal of the voltage generator;
• measure a value indicative of flow of the energy along the active terminal while commanding delivery of the energy;
• sum the value over a first predetermined window of time during delivery of the energy, to create a first value indicative of a first sum of the energy delivered along the active terminal;
• and
• sum the value over a second predetermined window of time during the delivery of the energy, to create a second value indicative of a second sum of the energy delivered from the active terminal, the second predetermined window being of shorter length than the first predetermined window, and the second predetermined window coextensive with the first predetermined window;
• and command the voltage generator to cease delivery of the energy responsive to the first value meeting or exceeding a predetermined value or the second value meeting or exceeding a threshold value.

A non-transitory computer-readable medium configured to store a program that, when executed by a processor is configured to cause the processor to:

• command delivery of energy to an active terminal of a voltage generator;
• measure a value indicative of flow of the energy along the active terminal, while delivering the energy;
• sum the value over a first predetermined window of time while delivering the energy, resulting in a first value indicative of a summed energy provided along the active terminal;
• command the voltage generator to cease delivering the energy responsive to the first value meeting or exceeding a predetermined value;
• and
• calculate a first quiescent time while commanding the voltage generator to cease delivering, the first quiescent time representing an amount of time remaining in the first predetermined window of time;
• and
• command the processor to resume delivering the energy once the first quiescent time is complete.

An electrosurgical method comprising:

• delivering energy to an active electrode of an electrosurgical wand, and during the step of delivering energy:
• measuring a value indicative of flow of the energy to the active electrode;
• summing the value over a first predetermined window of time, to create a first value indicative of a sum of the energy delivered to the active electrode;
• and
• summing the value over a second predetermined window of time, to create a second value indicative of a second sum of the energy provided to the active electrode, the second predetermined window being of shorter length than the first predetermined window, and the second predetermined window coextensive with the first predetermined window;
• and
• ceasing the step of delivering the energy responsive to either the first value meeting or exceeding a predetermined value or the second value meeting or exceeding a threshold value.
