Abstract
Embodiments are directed to various monopolar and bipolar electrosurgical scissor instruments. A monopolar electrosurgical scissor instrument includes 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 electrically insulated 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 includes a conductor that transfers electrical energy from an energy source to the tapered edge of the first electrically conductive scissor blade to electrically cut interlaying tissue located between the first electrically conductive scissor blade and the second electrically insulated scissor blade.
