Abstract
A bipolar cutter has a cutter main body for inserting into the interior of a body and a treating electrode that is positioned against an object of examination (such as a blood vessel or a bleeding site) to be electrically cut and cauterized. A guiding member guides the object of examination toward the treating electrode as it is displaced in the axial direction of the cutter main body. The guiding member is comprised of a pair of protruding members and a notched groove or gap that leads to the treating electrode while in a first configuration. A gap adjusting mechanism causes the guiding member or the treating electrode to be displaced in the axial direction to reduce or eliminate the length of the gap so that the treating electrode can better reach flat tissue surfaces for treatment.
