Abstract
Embodiments are directed to various monopolar and bipolar electrosurgical scissor instruments. An electrosurgical scissor instrument includes at least one scissor blade that has an electrically conductive tapered edge, where the tapered edge is insufficiently sharp to shear or otherwise mechanically cut tissue. The scissors also include another scissor blade movably mounted to the first scissor blade. The second scissor blade includes a flat contact surface that is aligned with the tapered edge of the first scissor blade. The scissors further include a scissor body that transfers electrical energy from an energy source to at least one of the scissor blades to electrically cut interlaying tissue located between the blades. In a monopolar embodiment, only one blade is conductive; whereas, in a bipolar embodiment, both blades are conductive.
