| 1. A digital depth gauge apparatus for measuring a depth of a hole in an object that is within a deep surgical field, the
apparatus comprising:
an elongated reader shaft that includes a distal end and a proximal end;
a user interface portion configured at the proximal end of the elongated reader shaft, the user interface portion including
a display and at least one actuator that controls operation of at least one of the display and the apparatus;
a probe that couples with and extends from the distal end of the reader shaft, the probe including a tip configured to locate
a distal surface of the object;
a sleeve member that includes a distal end configured to abut a proximal surface of the object, the sleeve member being coupled
with the elongated reader shaft for relative translational and rotational movement with respect to a longitudinal axis through
the elongated reader shaft; and
a sensor interposed between the elongated reader shaft and the sleeve member for measuring relative translational movement
between the elongated reader shaft and the sleeve member.
