Methods and apparatus for surgical cutting

TLDR
An electrosurgical probe comprises a shaft having an electrode array (12) at its distal end and a connector at its proximal end as mentioned in this paper, which is used to cut or ablate target tissue while heat dissipation through low impedance paths.
Abstract
An electrosurgical probe comprises a shaft having an electrode array (12) at its distal end and a connector at its proximal end. The array (12) includes a plurality of isolated electrode terminals, and an electrosurgical power supply (28) is provided with a multiplicity of independently limited or controlled current sources and a connector. The electrosurgical probe and the power supply may be connected through their respective connectors so that the independent current sources are connected to individual electrode terminals. By applying very high frequency electrical energy to the electrode array, target tissue may be cut or ablated while heat dissipation through low impedance paths, such as blood and normal saline, will be minimized.

Patent

Electrosurgical bipolar treating apparatus

TL;DR: An electrosurgical bipolar treating apparatus comprising a handpiece to which is connected a first active electrode and a second return electrode having exposed distal ends which define a bipolar tip for electrosurgically treating tissue at an operational site on a patient, which tip is structured so that both distal end simultaneously contact said tissue and wherein the active electrode has a higher tissue to electrode impedance than the return electrode as mentioned in this paper.
