Apparatus for implantation into bone |
摘要 |
An anchor is implantable into a bone in a patient's body and, when implanted, is resistant to toggling in the bone and to being pulled from the bone. The anchor includes a head end portion having a surface that extends transverse to a central axis of the anchor and is engagable with the bone. A plurality of helical spikes extend from the surface on the head end portion and are engagable with the bone. Each of the plurality of helical spikes has a helical central axis that forms a helix around the central axis of the anchor. Each of the plurality of helical spikes further has a circular cross-sectional configuration as viewed in a plane extending perpendicular to the helical central axis of each of the helical spikes and a distal end portion with a tip that penetrates the bone as the head end portion is rotated relative to the bone.
