| 摘要 |
A bipolar coagulating instrument includes a blade-like electrode assembly comprising an upper planar face and a lower planar face separated by an intermediate portion of insulating material therebetween. The upper face includes first and second electrodes separated by a first insulating member, and the lower face includes third and fourth electrodes separated by a second insulating member. The first and second insulating members are out of correlation one with respect to the other, such that there is at least one region in which the first electrode overlies the third electrode, and at least one other region in which the first electrode overlies the fourth electrode. A cutting electrode is provided between the upper and lower faces, extending marginally beyond the periphery thereof.
