Electrical flux delivery and return configurations for electrical flux delivery instruments, and related systems and methods

An electrosurgical flux supply unit, comprising:

• first and second terminals configured to be electrically coupled with first and second electrodes, respectively, of a first end effector of a first bipolar electrosurgical instrument operably coupled to the electrosurgical flux supply unit;
• third and fourth terminals configured to be electrically coupled with third and fourth electrodes, respectively, of a second end effector of a second bipolar electrosurgical instrument operably coupled to the electrosurgical flux supply unit;
• an electrosurgical flux source terminal;
• an electrosurgical flux return terminal;
• and
• an electrical switching mechanism selectively configurable between a first state and a second state, wherein:
• in the first state, the electrosurgical flux source terminal is electrically coupled with the first terminal and the electrosurgical flux return terminal is electrically coupled with the second terminal, and
• in the second state, the electrosurgical flux source terminal is electrically coupled with the third terminal and the electrosurgical flux return terminal is electrically coupled with the second terminal,
• wherein the electrosurgical flux supply unit is configured to:
• in the first state, supply bipolar electrosurgical flux to flow between the electrosurgical flux source terminal and the electrosurgical flux return terminal;
• and
• in the second state, supply monopolar electrosurgical flux to flow between the electrosurgical flux source terminal and the electrosurgical flux return terminal.
