Abstract: An electrosurgical generator arranged to supply radio frequency (RF) energy to fuse tissue is provided. The generator is arranged to supply RF energy through a removably coupled electrosurgical instrument to fuse tissue grasped by the instrument. The generator monitors a phase angle of the supplied RF energy and adjusts or terminates the supplied RF energy based on the monitored phase angle in comparison to predetermined thresholds and conditions to optimally fuse the tissue. The electrosurgical instrument conducts radio frequency energy to fuse tissue captured between the jaws and a blade to mechanically cut tissue between the jaws. A conductive post positioned on the jaw adjacent to the blade.

Abstract: A bipolar electrosurgical fusion/sealer and dissector is provided that is arranged to simultaneously fuse and cut tissue captured between jaws of the instrument. The jaws include particularly positioned, shaped and/or oriented electrodes along with a compressible landing pad to perform the simultaneous fusion and cutting of tissue. An electrosurgical generator is arranged to supply RF energy through the instrument and monitors a phase angle of the supplied RF energy and adjusts or terminates the supplied RF energy based on the monitored phase angle to optimally fuse and dissect the tissue.
