1. A surgical tool for probing bone near neural elements, comprising:

  • an elongate member extending along a longitudinal axis, said elongate member comprising;

    an exposed electrically conductive portion near its distal end for insertion into bone material;

    insulated surface area between said distal and a proximal end;

    a conductive path between said electrically conductive portion and said proximal end;

    a handle assembly having continuously curved surfaces at interfaces with a user'"'"'s hand, said handle assembly being attachable near said proximal end of said elongate member and comprising;

    an electrically insulated surface area;

    an electrically conductive area internal to said electrically insulated surface area and engageable with said proximal end of said elongate member;

    said handle assembly including a gripping portion having a major dimension at least 50% greater than a minor dimension, said major and minor dimensions being measured orthogonally to said longitudinal axis and to one another; and

    an electrical lead extending from said electrically conductive area through said handle assembly.
