1. An electrosurgical surgical instrument to staple, resect, and seal an anatomical structure of a patient, the surgical instrument comprising:
(a) an end effector, the end effector comprising;
(i) an anvil that includes a first end, a second end, and an anvil face positionable on a first side of the anatomical structure;
(ii) a cartridge operably configured to house a plurality of staples, the cartridge comprising a first end, a second end, and a cartridge face positionable on a second side of the anatomical structure, the cartridge face defining a channel extending from the first end of the cartridge to the second end of the cartridge, wherein the first end of the cartridge is pivotally coupled with the first end of the anvil;
(iii) a blade assembly comprising a blade, a beam, and a nut, the blade comprising a first side and a second side joined at a cutting edge, wherein at least a portion of the blade assembly is slidably engaged with the channel;
(iv) first and second electrodes coupled to the first side of the blade; and
(b) an elongate tube, the elongate tube having a proximal end and a distal end, wherein the distal end is coupled with the end effector;
(c) a handle, the handle having a proximal end and a distal end, wherein the distal end of the handle is coupled with the proximal end of the elongate tube;
(d) a drive assembly comprising a motor to actuate the end effector; and
(e) an electrosurgical power generating source, wherein circuitry connects each of the first and second electrodes to the electrosurgical power generating source, and wherein the circuitry comprises a first conductive strip coupled to an inside surface of the elongate tube and a second conductive strip coupled to an inside surface of the elongate tube.
