Anchor delivery system
The present disclosure relates to an anchor delivery system. The system includes a guide and an anchor delivery tool disposed within the guide. The tool includes a shaft and a handle coupled to a proximal portion of the shaft. The handle includes a hub and a nose cone coupled to the hub. In an embodiment, the tool further includes a knob coupled to the hub and located between the handle and the nose cone. In an embodiment, the system further includes an anchor, such as a suture anchor, coupled to a distal portion of the shaft. An anchor delivery tool and a method of repairing soft tissue are also disclosed.
1. A method of repairing soft tissue comprising: providing a guide; providing an anchor delivery tool, the tool including a shaft and a monolithic handle, consisting of a handle portion and a hub portion, coupled to the shaft, and a nose cone coupled to the hub, the hub disposed within a bore of the nose cone, the shaft including a suture anchor coupled to a distal end of the shaft, suture extending along lengths of the anchor and the shaft and through a proximal portion of the anchor, the handle portion including suture retaining tabs and the nose cone including a slotted opening, ends of the suture retained by the tabs and the slotted opening; introducing the guide into a body; advancing the tool through the guide; placing the anchor in bone; and securing the tissue to the bone.
2. The method of claim 1 further comprising a knob coupled to the hub, the hub disposed within a bore of the knob, the knob located between the handle and the nose cone, the knob movable along the hub.
3. The method of claim 1 wherein introduction of the guide into the body occurs in a percutaneous manner via the use of an obturator.
4. The method of claim 3 wherein the obturator is cannulated.
5. The method of claim 1 wherein full advancement of the tool into the guide is obtained when a distal portion of the nose cone abuts a proximal portion of the guide.
6. The method of claim 5 wherein both the distal portion of the nose cone and the proximal portion of the guide are flat.
7. The method of claim 1 wherein full advancement of the tool into the guide is obtained when a laser mark at a distal portion of the tool is centered in an opening at a distal portion of the guide.
8. The method of claim 1 wherein a proximal portion of the anchor is located below a surface of the bone once the anchor is placed in the bone.
9. The method of claim 1 wherein a proximal portion of the anchor is located below a surface of the bone when a distal portion of the nose cone abuts a proximal portion of the guide.
10. The method of claim 1 wherein a proximal portion of the anchor is located below a surface of the bone when a laser mark at a distal portion of the tool is centered in an opening at a distal portion of the guide.
11. The method of claim 1 wherein the tool is located at an angle relative to the bone upon placement of the anchor in the bone.
12. The method of repairing soft tissue of claim 1 wherein a shaft of the guide is bent relative to a longitudinal axis of the guide.
