    • 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.
    • 手术器械可以包括沿着第一线定位的两个正电极和沿着第二线定位的两个负电极,其中第一线可以垂直于第二线。 为了扩大由电极产生的电压场,正电极可以被定位成比负极更远离中心轴。 在各种实施例中,手术器械可以包括沿着第一线定位的第一电极阵列和沿着第二线定位的第二电极阵列。 在至少一个实施例中,第一电极阵列可以包括正电极和负电极,并且另外,第二电极阵列可以包括正极和负极。
