The present invention discloses a surgical instrument integrating an ultrasonic scalpel and a monopolar electric scalpel. The instrument has a built-in control mechanism that can switch between the ultrasonic scalpel component and the monopolar electric scalpel component. The control mechanism can synchronously switch the mechanical transmission structures and electronic signal circuits corresponding to the ultrasonic scalpel component and the monopolar electric scalpel component, respectively, to ensure that the monopolar electric scalpel and the ultrasonic scalpel are not powered on at the same time, thereby ensuring the reliability and safety of the monopolar electric scalpel and the ultrasonic scalpel when switching between them.

Electrosurgery blades for use in electrosurgical pencils used for electrosurgery. One exemplary embodiment of the monopolar electrosurgery blade includes a thin conductive member having opposing planar sides, a top, a bottom, a lead sharp cutting edge, an opposite non-cutting end, and a non-conductive coating covering the thin conductive member where at least a portion of both opposing planar sides that lie adjacent to the lead sharp cutting end remain exposed and where at least a portion of the top of the of the thin conductive member remains exposed.
