Bone graft delivery system and method for using same
A bone graft delivery system can include an elongate tube and a handle having a trigger and a ratcheting mechanism. The trigger is actuated to deliver bone graft material through the tube. The bone graft delivery system can further include a distal tip at a distal end of the tube. The tip has one or more openings to deliver the bone graft material to a desired location and includes a surface suitable to act as a rasp for decorticating bone. A method for delivering bone graft material to a desired surgical location includes providing a bone graft delivery device, positioning the device adjacent the surgical location, decorticating bone, and delivering bone graft material to the surgical location.
1. A method for delivering bone graft material to a surgical location, comprising:
loading a bone graft material into a lumen of a bone graft delivery device, the bone graft delivery device comprising:
an elongate tube, the lumen extending through the elongate tube; and
a rasp couplable to the elongate tube and comprising a surface suitable for scraping bone;
coupling a guide for use with an image-guided surgery system to the bone graft delivery device;
visualizing the guide with the image-guided surgery system;
advancing the bone graft delivery device towards the surgical location;
monitoring the position of the bone graft delivery device relative to the surgical location using the image-guided surgery system; and
advancing bone graft material within the lumen and to the surgical location when the bone graft delivery device is positioned at the surgical location.
2. The method of claim 1 , wherein the guide comprises one or more markers, wherein visualizing the guide with the image-guided surgery system comprises visualizing the one or more markers.
3. The method of claim 2 , wherein visualizing the one or more markers comprises visualizing the one or more markers using fluoroscopy or x-ray.
4. The method of claim 1 , further comprising positioning a reference frame at a reference location of the surgical location, wherein monitoring the position of the bone graft delivery device relative to the surgical location comprises monitoring the position of the bone graft delivery device relative to the reference frame.
5. The method of claim 4 , wherein the reference frame comprises one or more radiopaque markers.
6. The method of claim 4 , wherein monitoring the position of the bone graft delivery device relative to the reference frame comprises tracking the position of one or more markers of the guide relative to the position of one or more markers of the reference frame.
7. The method of claim 4 , further comprising coupling the reference frame to a pin at the reference location.
8. The method of claim 1 , wherein the image guided surgery system comprises one or more of an x-ray scanner, a CT scanner, a fluoroscope, and a camera.
9. The method of claim 1 , further comprising advancing a plunger into the lumen of the bone graft delivery device to advance the bone graft material within the lumen and to the surgical location when the bone graft delivery device is positioned at the surgical location.
10. The method of claim 9 , further comprising advancing the plunger into the lumen of the bone graft delivery device using a handle coupled to a proximal end of the elongate tube.
11. The method of claim 1 , further comprising decorticating bone at the surgical location using rasp.
12. A bone graft delivery system, comprising:
a bone graft delivery device comprising:
an elongate tube;
a lumen extending through the elongate tube and configured to receive a bone graft material; and
a rasp couplable to the elongate tube and comprising a surface suitable for scraping bone;
a guide configured to couple to the bone graft delivery device, the guide comprising one or more markers; and
an image-guided surgery system configured to visualize the one or more markers of the guide.
13. The system of claim 12 , wherein the guide is configured to couple to the elongate tube.
14. The system of claim 12 , further comprising a reference frame configured to be positioned at a reference location of a surgical location, wherein the image-guided surgery system is configured to visualize the reference frame.
15. The system of claim 14 , further comprising a pin coupled to the reference frame.
16. The system of claim 14 , wherein the reference frame comprises one or more radiopaque markers, wherein the image guided-surgery system is configured to visualize the one or more radiopaque markers.
17. The system of claim 12 , wherein the image guided surgery system comprises one or more of an x-ray scanner, a CT scanner, a fluoroscope, and a camera.
18. The system of claim 12 , further comprising a plunger configured to be removeably received in the lumen.
19. The system of claim 18 , wherein the bone graft delivery device further comprises a handle at a proximal end of the elongate tube configured to be actuated to deliver bone graft through the elongate tube.
20. The system of claim 12 , wherein the surface of the rasp comprises jagged edges.
