Abstract
Disclosed are embodiments of a removable tip device, which include a bone penetration feature at a distal end and a securing feature that allows the removable tip device to be removably secured to a distal end of various embodiments of a bone coring device. Some embodiments of the removable tip device include features that assist in transmitting torsional loads from the bone coring device to the bone removal feature. In addition, some embodiments of the removable tip device include a protective element that is configured to provide a protective surface for a distal feature of the bone coring device.
Claims14
A removable tip device configured to releasably engage a bone coring device, the removable tip device comprising:
- an outer sleeve defining an interior sized to slide over an outer surface of a distal end of the bone coring device, the outer sleeve having a distal end region and a proximal end region;
- a bone penetration feature extending from the distal end region of the outer sleeve, the bone penetration feature being a sharp distal cutting tip configured to penetrate a layer of bone;
- a compliant protective element configured to be positioned within the interior of the outer sleeve and resting against or adjacent to a distal cutting edge of the bone coring device, the protective element configured to provide a protective surface for the distal cutting edge of the bone coring device so as to prevent damage to the distal cutting edge during application of a load against the compliant protective element by the distal cutting edge;
- and
- a securing feature configured to extend from the proximal end region of the outer sleeve, the securing feature configured to releasably engage the distal end of the bone coring device.
