A device for examination and measurement of a hole formed through a bone, the device comprising: a handle including a first end and a second end ; a bone probe slidably mounted within the handle and comprising unitary construction, the bone probe comprising a shaft including a distal end comprising a probing tip extending therefrom, the probing tip comprising: a first portion shaped and configured to contact an interior surface of the hole with little or no resistance and provide tactile feedback of the interior surface of the hole to a user; and a second portion defining a top portion having a substantially planar top surface oriented at an angle relative to a longitudinal axis of the bone probe shaft , the second portion including an engagement surface shaped and configured to establish purchase with an exterior surface of bone adjacent to the hole upon sufficient application of force to the shaft ; wherein the bone probe comprises a notch formed at a junction between the second portion of the probing tip and the distal end of the bone probe shaft ; a depth gauge member slidably mounted within the handle , the depth gauge member comprising a hollow elongate body including a distal end , the hollow elongate body including a lumen in which at least a portion of the bone probe shaft is received such that the bone probe and depth gauge member are independently slidable relative to one another and the handle ; and a sensor configured to generate an electronic signal indicative of a depth of the hole, wherein the electronic signal varies in relation to a distance between the first end of the handle and the distal end of the hollow elongate body of the depth gauge member . a handle including a first end and a second end ; a bone probe slidably mounted within the handle and comprising unitary construction, the bone probe comprising a shaft including a distal end comprising a probing tip extending therefrom, the probing tip comprising: a first portion shaped and configured to contact an interior surface of the hole with little or no resistance and provide tactile feedback of the interior surface of the hole to a user; and a second portion defining a top portion having a substantially planar top surface oriented at an angle relative to a longitudinal axis of the bone probe shaft , the second portion including an engagement surface shaped and configured to establish purchase with an exterior surface of bone adjacent to the hole upon sufficient application of force to the shaft ; a first portion shaped and configured to contact an interior surface of the hole with little or no resistance and provide tactile feedback of the interior surface of the hole to a user; and a second portion defining a top portion having a substantially planar top surface oriented at an angle relative to a longitudinal axis of the bone probe shaft , the second portion including an engagement surface shaped and configured to establish purchase with an exterior surface of bone adjacent to the hole upon sufficient application of force to the shaft ; wherein the bone probe comprises a notch formed at a junction between the second portion of the probing tip and the distal end of the bone probe shaft ; a depth gauge member slidably mounted within the handle , the depth gauge member comprising a hollow elongate body including a distal end , the hollow elongate body including a lumen in which at least a portion of the bone probe shaft is received such that the bone probe and depth gauge member are independently slidable relative to one another and the handle ; and a sensor configured to generate an electronic signal indicative of a depth of the hole, wherein the electronic signal varies in relation to a distance between the first end of the handle and the distal end of the hollow elongate body of the depth gauge member . <EOS>
