Vessel sealing using a pulsed bipolar system and open forceps.
We evaluated the vessel-sealing ability of one application of a pulsed plasma kinetic (PK) electrosurgical device on skeletonized vessels up to 7 mm in diameter to withstand sustained pressure of 300 mm Hg using bench and animal models. Forty-six porcine specimens and 66 abattoir vessels (112 total) were pressure tested after sealing with a pulsed PK system. Of these, 108 (96%) met the criterion of 300 mm Hg pressure held for 10 seconds without leaking. The PK system open forceps effectively closes vessels and maintains closure at a pressure level sufficient for clinical use. The device is more effective than clips, sutures, and staples.
