1. A surgical tool comprising:

  • a first arm and a second arm;

    a first tip extending from the first arm and having a first inner side and an opposed first exterior side;

    a second tip extending from the second arm and having a second inner side and an opposed second exterior side;

    a first plurality of connecting elements, the first plurality of connecting elements comprises a first connecting element extending from the first arm and a second connecting element extending from the second arm;

    a plurality of contacting elements that are conductive and configured to contact tissue of a patient in proximity of a nerve, the plurality of contacting elements including a first contacting element associated with the first tip and a second contacting element associated with the second tip; and

    a plurality of conductive elements distinct from the first plurality of connecting elements and extending from the first plurality of connecting elements to the plurality of contacting elements, wherein the plurality of conductive elements have respective insulative outer layers, wherein the insulative outer layers isolate the plurality of conductive elements from each other,wherein the first plurality of connecting elements are configured to connect to and receive a plurality of monophasic stimulation pulses from a second plurality of connecting elements on a modular stimulation module, wherein the modular stimulation module is configured to connect to the tool and a plurality of other tools via the second plurality of connecting elements,wherein the plurality of conductive elements are configured to transfer current from the plurality of monophasic stimulation pulses from the first plurality of connecting elements to the plurality of contacting elements,wherein the first inner side of the first tip faces the second inner side of the second tip,wherein the first contacting element is on the first exterior side of the first tip and the second contacting element is on the second exterior side of the second tip such that the first and second contacting elements are on the opposite exterior sides of the first and second tips and do not face each other.
