International Classification:

A61B 18/12
A61B 18/14

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.

International Classification:

A61B 18/14

Abstract:

Disclosed is a method of adapting energy modality due to a short circuit or tissue type grasped in the jaws of an end effector of a surgical instrument. The method includes selecting an electrode in an array of segmented electrodes during a pre-energy activation cycle. The method includes applying a sub-therapeutic electrical signal to the selected electrode to differentiate between a shorted electrode and low impedance tissue grasped in the jaws of the end effector. The method includes determining the selected electrode is shorted based on a measured electrical parameter received by the control circuit after applying the sub-therapeutic electrical signal and blending monopolar and bipolar RF energy. The method includes determining that the selected electrode is shorted and switching output energy of the RF generator between monopolar and bipolar RF energy.
