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.

Abstract
A surgical tool for probing bone tissue includes an elongate member coupled to a handle assembly. The handle assembly is electrically coupled to a electrical signal source. The surgical tool includes an electrically conductive portion in communication with an un-insulated distal end of the elongate member, and insulated portion extending from the tip along the elongate member and handle assembly.
