1. A surgical forceps comprising:

  • a first working arm and a second working arm configured to move in a direction that is towards each other and a direction away from each other, and the first working arm and the second working arm are movable in the direction towards each other or the direction away from each other, in a manner that creates a resilient moving force;

    an electromagnetic latching system including two or more electromagnetic latches;

    wherein the electromagnetic latching system is configured to create a force that is superimposed upon the resilient moving force, wherein the force comprises one or more of the following;

    (i) the force biases the first working arm, the second working arm, or both in a direction of the resilient moving force;

    or(ii) the force biases the first working arm, the second working arm, or both in an opposite direction as the resilient moving force; and

    wherein a bipolar current extends between the first working arm and the second working arm and the force is created when a first activation button is energized; and

    wherein the electromagnetic latching system has fine adjustment by a first of the two or more electromagnetic latches creating the force and a second of the two or more electromagnetic latches creating one or more adjustable forces that are applied in a same direction, an opposite direction, or both as the force forming an adjusted force so that the adjusted force assists a user in moving the first working arm and the second working arm together or apart.
