Abstract:
1. An instrument for measuring blind holes in one of (a) bones and (b) implants inserted within bones, comprising: a. an elongated probe having a proximal end, a distal end, a longitudinal axis, and a scale on the proximal end of the probe; b. a housing slidably mounted relative to the scale and having a length that is less than a length of the elongated probe; c. an abutment formed at the distal end of the probe, the abutment configured and dimensioned to fit through a hole to be measured; and d. an elongated insert having a longitudinal groove for receiving the probe in a sliding engagement with respect thereto, wherein a retraction of the insert in a direction away from the hole causes movement of the abutment toward a distal wall adjacent the hole.
