摘要： Bone anchors, after insertion into bone, are designed to remain in place and provide a platform for holding tissue. A method of ultrasonically embedding bone anchors into bone without pre-drilling an anchor receiving hole into the bone has been developed. Also described is an improved bone anchor embedding method utilizing ultrasonic energy to reduce insertion force, whereby the bone anchor and embedding device can be formed very small, (e.g. on the order of 2 to 5 millimeters in diameter). In an embodiment of the present invention, a method of bone anchor embedding utilizing ultrasonic energy is used to insert a bone anchor into a pre-drilled hole, wherein the hole in the bone may be smaller in diameter than the diameter of the bone anchor.

摘要： Bone anchors, after insertion into bone, are designed to remain in place and provide a platform for holding tissue. An ultrasonic bone anchor is described, comprising a proximal end, a distal end, and a body between the proximal end of the bone anchor and the distal end of the bone anchor. There is an outer surface on the body of the bone anchor which may include at least one protrusion extending from the outer surface of the bone anchor body. A coupling element is located at the proximal end of the bone anchor. The ultrasonic bone anchor is adapted to reciprocate at an ultrasonic frequency with an excursion of 50 to 300 micrometers. An embodiment of the present invention includes an ultrasonic bone anchor wherein the coupling element includes threads formed in a right-hand screw pattern, and the protrusion is formed in a left-hand screw pattern. Alternately the threads may be formed in a left-hand pattern and the protrusion formed in a right-hand pattern.
