摘要：
Electrosurgery method and apparatus. In the method, tissue is cut or coagulated,with an electrically low conductive liquid providing cooling. In another method,skin is cut by electrosurgery in a dry field using a low duty cycle signal energizingthe cutting electrode, minimizing tissue charring. A combination coagulationand cutting electrode performs both functions. The cutting is performed by ablade edge generating a local plasma adapted for cutting. Superimposed on theblade edge is an electrode of greater surface area electrically insulated fromthe cutting electrode, for coagulation. In another version, a single componentcutting/coagulation blade (electrode) has a cutting and a flat partially insulatedportion defining through holes in the insulation for coagulation. Also providedis an electrical circuit whereby each electrode is isolated by a filter from crosstalk and feedback of the RF signal from the other electrode, minimizing arcing.
