Abstract
A device configured to provide a faster and more accurate measurement of depths of holes for placement of bone screws and fastener for bone implant fixation procedures. The device includes a combination of a bone probe for physical examination of a hole drilled in a bone and a depth gauge member for determining a depth of the hole and providing digital measurement of the depth.
Claims15
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 configured to be advanced through a hole formed through a bone and establish purchase with an exterior surface of the bone adjacent to a hole;
- a depth gauge cylinder slidably mounted to a portion of the handle, the depth gauge cylinder comprising a lumen in which at least a portion of the handle and the bone probe shaft are received, wherein the depth gauge cylinder is operable to slide along a longitudinal axis of the handle;
- a tip member releasably couplable to a distal end of the depth gauge cylinder, the tip member comprising an opening through which at least the bone probe shaft is received;
- and
- a sensor configured to generate an electronic signal based on a distance traveled by the depth gauge cylinder relative to the handle and bone probe.
