Abstract

See full text

A surgical instrument can comprise two positive electrodes positioned along a first line, and two negative electrodes positioned along a second line, wherein the first line can be perpendicular to the second line. The positive electrodes can be positioned further away from a central axis than the negative electrodes in order to expand the voltage field created by the electrodes. In various embodiments, a surgical instrument can comprise a first array of electrodes positioned along a first line and a second array of electrodes positioned along a second line. In at least one embodiment, the first array of electrodes can comprise both positive and negative electrodes, and, in addition, the second array of electrodes can comprise both positive and negative electrodes.
