| Abstract | An electrosurgical instrument has a power supply operatively coupled to an end effector. The end effector has a pair of jaws for effectuating an action on tissue positioned therebetween. The power supply is configured to input a first signal and a second signal to a buck-boost converter. The buck-boost converter is configured to transmit an output to an H-bridge circuit. The H-bridge circuit is configured to pass a signal to a resonant LC transformer circuit. The power supply is configured to transmit a power signal. The pair of jaws are operatively coupled to the power supply to receive the power signal, the power having no more than 80 Volts RMS, and less than 2 Amps RMS. The power is configured to seal the tissue positioned between the pair of jaws in 3 seconds or less. |
