Ultrapolar electrosurgery blade and pencil for use in esu monopolar and bipolar modes

Abstract

An ultrapolar electrosurgery blade and an ultrapolar electrosurgery pencil that can be used in both monopolar and bipolar modes for cutting and coagulating tissue. The ultrapolar electrosurgery blade includes a non-conductive member with opposing planar sides having completely planar surfaces throughout, a cutting end with a sharp cutting edge, and an opposite non-cutting end, an active electrode located on one of the opposing planar sides of the non-conductive member, and a return electrode located on the other opposing planar side of the non-conductive member.

No. 15 / 697,335 filed Sep. 6, 2017 which claims priority to provisional patent application having Ser. No. 62 / 383,855 entitled “Ultrapolar Electrosurgery Blade and Pencil for Use in ESU Monopolar and Bipolar Modes,” filed Sep. 6, 2016, which are herein incorporated by reference in their entireties.FIELD OF INVENTION[0002]The present invention is generally directed to an ultrapolar electrosurgery blade and an ultrapolar electrosurgery pencil for use in both monopolar mode and bipolar mode for cutting and coagulation. The ultrapolar electrosurgery blade has a non-conductive member with opposing planar sides, a cutting end, and an opposite non-cutting end, an active electrode located on one of the opposing planar sides of the non-conductive member, and a return electrode located on the other opposing planar side of the non-conductive member.BACKGROUND OF THE IN...

AI Technical Summary

Benefits of technology

The ultrapolar electrosurgery blade enables flexible cutting and coagulation of large tissue areas with reduced tissue damage and minimal energy passing through the patient, using low power levels and minimizing smoke production, while maintaining safety by eliminating the need for a return electrode pad on the patient.

Problems solved by technology

However, the excessive heat generated with monopolar electrosurgery can cause excessive tissue damage and necrosis of the tissue because the return electrode positioned on the back of the patient causes high voltage and high RF energy to pass through the patient.

Although bipolar electrosurgery enables the use of lower voltages and less energy and thereby reduces or eliminates the likelihood of tissue damage and sparking associated with monopolar electrosurgery, it has limited ability to cut and coagulate large bleeding areas.
