A novel pulsed plasma kinetic (PK) electrosurgical device effectively seals vessels up to 7 mm. This advanced vessel sealing technology demonstrated superior performance compared to traditional methods in pressure tests.

Area of Science:

  • Surgical Technology
  • Electrosurgery
  • Vascular Surgery

Background:

  • Effective vessel sealing is critical in surgical procedures to minimize blood loss.
  • Existing methods like clips, sutures, and staples have limitations in certain applications.
  • Advancements in electrosurgical devices aim to improve sealing efficacy and efficiency.

Purpose of the Study:

  • To evaluate the vessel-sealing capability of a pulsed plasma kinetic (PK) electrosurgical device.
  • To determine the pressure resistance of vessels sealed by the PK system.
  • To compare the PK system's effectiveness against conventional sealing methods.

Main Methods:

  • Utilized bench and animal models, including 46 porcine specimens and 66 abattoir vessels (112 total).

  • Applied a single application of the PK electrosurgical device to skeletonized vessels up to 7 mm in diameter.
  • Pressure tested sealed vessels to a sustained pressure of 300 mm Hg for 10 seconds.

    • Main Results:

    • 96% (108 out of 112) of sealed vessels met the criterion of withstanding 300 mm Hg pressure for 10 seconds without leaking.
    • The PK system's open forceps demonstrated effective vessel closure.
    • The device maintained closure at a pressure level deemed sufficient for clinical application.

    Conclusions:

    • The pulsed plasma kinetic (PK) electrosurgical device provides reliable and effective vessel sealing.
    • The PK system offers superior performance in maintaining hemostasis under pressure compared to clips, sutures, and staples.
    • This technology presents a promising advancement for surgical hemostasis in various clinical settings.
