Abstract: An end effector of a forceps includes first and second jaw members movable between spaced-apart and approximated positions for grasping tissue. Each jaw member includes a tissue sealing plate that is selectively energizable. The tissue sealing plates are configured to conduct energy therebetween and though tissue to seal tissue. A knife includes a distal surface and an upper surface. The knife is selectively translatable between a retracted position and an extended position wherein the knife extends between the jaw members. The distal surface is configured for dynamic tissue cutting upon translation of the knife from the retracted to the extended position. The upper surface is configured for static tissue cutting with the knife in the extended position. The knife is selectively energizable and is configured to conduct energy between the knife and one or both of the tissue sealing plates and through tissue to electrically cut tissue.

Abstract: An end effector assembly includes opposed jaws moveable from an open to a closed position for grasping tissue therebetween. Each jaw includes an electrically conductive surface adapted to conduct electrosurgical energy through tissue disposed between the jaws. A static bipolar cutting portion including at least one electrically conductive cutting element and at least one insulating element having a first configuration is disposed on at least one of the jaws. The static cutting portion is configured to electrically cut tissue disposed between the jaws upon activation of the cutting element and at least one of an opposing sealing surface and an opposing cutting element. A dynamic cutting portion including at least one electrically conductive cutting element and at least one insulating element having a second configuration is disposed on at least one of the jaws. The dynamic cutting portion electrically transects tissue during movement relative to tissue.

Abstract: The systems and methods according to embodiments of the present disclosure provide optimal tissue effect during an electrosurgical procedure. A system and method for controlling an electrosurgical generator is provided including sensing an impedance of target tissue; generating electrosurgical energy in a first phase at a first power level until the sensed impedance of the target tissue is greater than a first threshold impedance; generating a plurality of pulses of electrosurgical energy in a second phase at a second power level, each pulse being generated until the sensed impedance of the target tissue is greater than a second threshold impedance set for that pulse; and generating at least one high-voltage pulse in a third phase at a third power level for a predetermined duration to divide the target tissue.
