A surgical cautery device, system, and method of use may apply bipolar and/or sesquipolar electrocautery to target tissue via a pair of instruments with other primary surgical functions. The surgical cautery device and system may include first and second elements capable of forming an electrical circuit. The second element may be independently positionable with respect to the first element. The first and second elements may also include a surgical component with an independent surgical function. Exemplary surgical components include a rotary blade, a cutting tool, a grasper tool, a micro-scissors tool, a micro-grasping forceps tool, a dissector, a micro-dissector, curette, and a suction cannula. On some occasions, one of the surgical components may be interchangeable with another surgical component.
