Bone suture
Devices and methods useful for suturing soft tissue to bone are disclosed. In one embodiment, a bone-suturing device is provided and can include a delivery needle, a delivery needle driving element, a capture needle, and a capture needle driving element. The delivery needle driving element and capture needle driving element can advance the delivery needle and the capture needle through soft tissue and into bone, respectively, and the paths of the delivery needle and the capture needle can intersect therein. The delivery needle can be adapted for holding a suture and the capture needle can be adapted for receiving the suture held by the delivery needle. In another embodiment, an injection device can be provided to deliver an adhesive material into bone. The devices and methods disclosed herein can provide simple and minimally invasive ways to suture soft tissue to bone with a high resistance to pullout and reduced recovery time, and may be used as part of percutaneous, arthroscopic, or open surgical procedures.
1. A method for suturing soft tissue to bone, comprising:
driving a delivery needle into bone, the delivery needle adapted to deliver a suture to bone;
driving a capture needle into bone, without first pre-drilling a hole in the bone for the needle, such that a path of the capture needle intersects a path of the delivery needle;
passing the suture from the delivery needle to the capture needle to withdraw the suture through the path of the capture needle; and
securing the soft tissue to the bone with the suture.
2. The method of claim 1 , wherein the method is conducted percutaneously.
3. The method of claim 1 , wherein the steps of driving the delivery needle and the capture needle involve piercing the soft tissue.
4. The method of claim 1 , further comprising the step of inserting a cannula into the skin and inserting the delivery needle and the capture needle through the cannula.
5. The method of claim 1 , wherein the steps of driving the delivery needle and the capture needle are performed at least in part ultrasonically.
6. The method of claim 1 , wherein the paths of the delivery needle and the capture needle intersect in cancellous bone.
7. The method of claim 1 , wherein the step of securing the soft tissue to bone involves securing free ends of the suture outside the bone with at least one of a knot and a fastener.
8. The method of claim 1 , wherein the suture is delivered to the bone simultaneously with the step of driving the delivery needle into the bone.
9. The method of claim 1 , wherein the suture is delivered to the bone after the step of driving the delivery needle into the bone.
10. The method of claim 1 , wherein the step of securing the soft tissue to the bone involves placing the soft tissue on the bone and driving the delivery needle and the capture needle through the soft tissue to be sutured.
11. The method of claim 1 and further comprising the step of delivering an adhesive material to an intersection of the paths of the delivery needle and the capture needle.
