Abstract: A bipolar forceps includes a mechanical forceps including first and second shafts each having a jaw member extending from a distal end thereof and a handle disposed at a proximal end thereof for effecting movement of the jaw members relative to one another about a pivot. A disposable housing is configured to releasably couple to at least one of the shafts and an electrode assembly has electrodes releasably coupleable to the jaw members and adapted to connect to a source of electrosurgical energy to allow selective conduction of electrosurgical energy through tissue held therebetween to effect a tissue seal. An electrically conductive cutting element is disposed on at least one of the electrodes and is adapted to connect to the source of electrosurgical energy to allow selective conduction of electrosurgical energy through tissue held between the electrodes to effect a tissue cut.

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.

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.
