Bipolar coagulating instrument
First Claim
1. A bipolar coagulating instrument including a blade-like electrode assembly comprising an upper planar face and a lower planar face separated by an intermediate layer of insulating material therebetween, the upper face including first and second electrodes separated by a first insulating member and between which coagulation can be performed, and the lower face including third and fourth electrodes separated by a second insulating member and between which coagulation can be performed, the first and second insulating members being 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 also overlies the fourth electrode, whereby coagulation can be performed between the first and fourth electrodes.

Abstract
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.
