ABSTRACT:
Bipolar electrosurgical scissors for treating biological tissue include first and second scissor blades. A shearing surface and cutting edge of each blade is electrically neutral. The scissors include a pair of electrical connections for receiving electrical currents of opposing polarities. Each blade includes at least one first electrode and at least one second electrode positioned on a surface opposite the shearing surface The at least one first electrode on the first blade and the at least one second electrode on the second blade are coupled to the first electrical connection. The at least one second electrode on the first blade and the at least one first electrode on the second blade are coupled to the second electrical connection. In a first energized state, the electrical connections deliver electrical current only to the first electrodes. In a second energized state, the electrical connections deliver electrical current to all of the electrodes.
