The functionality and the output power delivered are evaluated in an electrosurgical generator by calculating first and second values related to the output power delivered by using separate first and second computations. The two calculated values are compared, and an error condition is indicated when the two values differ by a predetermined amount. The separate computations, coupled with the other separate activities of measuring, averaging and sampling the output current and voltage measurements, serve as an effective basis for detecting errors caused by malfunctions or equipment failure. The error condition may be used to as a basis to terminate the output power delivery or indicate the error.

Electrosurgical generator and method for cross-checking output power

The functionality and the mode of operation are evaluated in an electrosurgical generator by determining whether a patterned pulse signal that contributes to the generation of electrosurgical energy is as expected. A number of pulses in the patterned pulse signal is compared to an expected number of pulses, and an error condition is indicated when the two values are not the same or differ by more than a predetermined amount. The expected number of pulses depends on a mode of operation of the electrosurgical generator. The error condition may be used to as a basis to terminate the output power delivery.

Electrosurgical generator and method for cross-checking mode functionality

Output power delivery from an electrosurgical generator is evaluated to avoid malfunctions and risk conditions. Output power is delivered in a selected delivery path and the flow of output power is sensed in the selected delivery path and other delivery paths which have not been selected. The output power delivery is terminated upon determining that output power is not flowing in the selected delivery path or that output power is flowing in a delivery path that was not selected.
