| 摘要 |
<p>A suture anchor assembly (10) is described which includes an elongated insertion stem (12), and an approximately cylindrical anchoring element (20) having an axial channel (26) for receiving the insertion stem (12). In its non-expanded state, the anchoring element (20) can be placed into a pre-drilled opening in a bone. An expander element (35) loaded onto the insertion stem (12) is engaged with a proximal end (22) of the anchoring element (20). The proximal end (22) of the anchoring element (20) is capable of telescoping or cam movement over the distal end (40) of the expander element (35) so that resilient proximal portions of the anchoring element (20) are forced outward against the expander element (35) causing the resilient proximal portions of the anchoring element (20) to expand into the bone hole, fixing the anchoring element (20) in a pressure fit firmly within the opening. A kit for emplacing and removing the suture anchor is also provided, as well as methods for attaching a suture to a bone using the present assembly.</p> |
