electrocautery

 [e-lek″tro-kaw´ter-e]
1. an apparatus for surgical dissection and hemostasis, using heat generated by a high-voltage, high-frequency alternating current passed through an electrode.
2. the cauterization of tissue using such an instrument.
bipolar electrocautery an electrocautery in which both active and return electrodes are incorporated into a single handheld instrument, so that the current passes between the tips of the two electrodes and affects only a small amount of tissue.
monopolar electrocautery (unipolar electrocautery) an electrocautery in which current is applied through a handheld active electrode and travels back to the generator through an inactive electrode attached to the patient (the grounding pad), so that the patient is part of the electrical circuit.

bipolar electrocautery

an electrocautery in which both active and return electrodes are incorporated into a single handheld instrument, so that the current passes between the tips of the two electrodes and affects only a small amount of tissue.

D'Amelio commented, "Just as important as the development and clinical testing of our tissue fusion/welding generators and disposable instruments, is communicating about our unique bipolar electrocautery system and our results.
In an excellent article discussing the fundamentals of electrocautery devices, Zinder and Parker describe an incident of an inadvertent oral commissure burn from a bipolar electrocautery handpiece contacting the oral commissure during a routine tonsillectomy.
Obviously, the fact that our results differ from those of other studies does not mean that our data are unreliable; rather it suggests that more studies are indicated, in fact, we are planning another prospective study of bipolar electrocautery for hemostasis to explore its influence on the rate of primary hemorrhage.
