Bone anchor insertion device
First Claim
1. A method for making an orthopedic repair, by re-attaching a portion of soft tissue to a portion of adjacent bone, using a bone anchor insertion device comprising a handle and a nosepiece attached to a distal end of said handle, said method comprising:
- passing a length of suture through said portion of soft tissue so that a loop of suture is embedded therein;
threading free ends of the length of suture through a first snare, the first snare extending from the nosepiece;
wherein the first snare is coupled to a second snare that extends through the nosepiece, a bone anchor and the handle, the second snare further engaged with a suture tensioning mechanism in the handle;
pulling the second snare through the device to thereby cause the free ends of the length of suture to be threaded through the nosepiece, the bone anchor and the handle; and
securing the free ends of the length of suture to the suture tensioning mechanism in the handle;
locating said bone anchor so that it lies beneath a cortical bone surface of said portion of adjacent bone;
deploying said bone anchor so that it remains in place beneath said cortical bone surface;
actuating said suture tensioning mechanism to tension said length of suture, thereby approximating said soft tissue portion to said adjacent bone portion and said bone anchor as desired.

Abstract
A bone anchor insertion device is disclosed for attaching a suture that is fixed to portion of soft tissue to a portion of bone. The device has a handle, a nosepiece connected to a distal end of the handle, a bone anchor connected to the nosepiece, and an actuator disposed on the handle for deploying the bone anchor. A suture ratchet or tensioning mechanism is disposed in the handle for tensioning suture which is associated with the bone anchor. This mechanism permits precise tensioning, while also permitting one-handed operation, thereby allowing the practitioner to use his or her other hand for other activities, such as camera operation or the like.
