  • Patent number: 12232796
    Abstract: Disclosed is a method of detecting a short circuit in the jaws of an end effector of a surgical instrument. The method includes applying a sub-therapeutic electrical signal to an electrode located in the jaws of the end effector. The sub-therapeutic electrical signal comprises a sequence of exploratory waveforms comprising pulsed current and voltage waveforms. The method includes detecting a shorted electrode when a measured electrical parameter in the jaws of the end effector is less than a predetermined value and modifying electrical current applied to the shorted electrode by the RF generator.
    Type: Grant
