1. A device for examination and measurement of a hole formed through a bone, the device comprising:
a handle;
a bone probe fixed to the handle and extending from a distal end thereof, the bone probe comprising a shaft including a distal end defining a probing tip comprising a portion including at least an engagement surface shaped and configured to establish purchase with an exterior surface of bone adjacent to a hole upon sufficient application of force to the shaft;
a depth gauge cylinder slidably mounted to a portion of the handle, the depth gauge cylinder comprising a hollow body including a lumen in which at least a portion of the handle and the bone probe shaft are received within, wherein the depth gauge cylinder is operable to slide along a longitudinal axis of the handle;
a tip member releasably coupled to a distal end of the depth gauge cylinder and operable to correspondingly slide with the depth gauge cylinder, the tip member comprising an opening through which at least the bone probe shaft is received, the tip member further comprising a distal end; and
a sensor comprising a pressure sensitive strip coupled to a portion of the handle that is received by the hollow body of the depth gauge cylinder and configured to generate an electronic signal indicative of a depth of the hole, wherein the electronic signal varies in relation to distance traveled by the depth gauge cylinder relative to the pressure sensitive strip.
