Bone graft delivery system and method for using same
A bone graft delivery system can include an elongate tube, a handle having a trigger, and a tip. The trigger is actuated to deliver bone graft material through 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 bone graft delivery system, comprising:
an elongate tube;
a handle at a proximal end of the tube configured to be actuated to deliver bone graft material through the tube, the handle comprising:
a funnel at a proximal end of the handle, the funnel configured to receive bone graft material;
a channel extending between and in fluid communication with the funnel and the proximal end of the tube; and
a ratcheting mechanism configured to advance bone graft material from the funnel, through the channel, and into the tube; and
a plunger configured to be removably received in the channel and tube.
2. The bone graft delivery system of claim 1 , wherein the ratcheting mechanism is configured to advance the plunger distally within the channel and tube to advance bone graft material distally through the tube.
3. The bone graft delivery system of claim 1 , further comprising a distal tip at a distal end of the tube.
4. The bone graft delivery system of claim 3 , wherein the distal tip is removably coupled to the distal end of the tube.
5. The bone graft delivery system of claim 3 , wherein the distal tip is generally bullet shaped.
6. The bone graft delivery system of claim 3 , wherein the distal tip is generally flat.
7. The bone graft delivery system of claim 3 , wherein the distal tip comprises at least one rasping surface configured to decorticate bone.
8. The bone graft delivery system of claim 3 , wherein the distal tip comprises at least one opening configured to deliver bone graft material.
9. The bone graft delivery system of claim 1 , further comprising a shaft having a burr at a distal end, the shaft configured to be inserted through the tube and the burr configured to decorticate bone.
10. The bone graft delivery system of claim 1 , wherein the tube is straight.
11. The bone graft delivery system of claim 1 , wherein the tube is curved.
12. The bone graft delivery system of claim 1 , further comprising an endoscopic camera positioned adjacent the tube.
13. A method for delivering bone graft material to a surgical location, comprising:
providing a bone graft delivery device comprising an elongate tube and a handle at a proximal end of the tube, the handle comprising:
a ratcheting mechanism;
trigger operatively coupled to the ratcheting mechanism;
a proximal opening; and
a lumen extending between and in fluid communication with the proximal opening and the proximal end of the tube;
loading bone graft material into the bone graft delivery device;
positioning the device adjacent the surgical location;
inserting a plunger into the lumen and tube;
manipulating the trigger so that the ratcheting mechanism engages the plunger; and
delivering bone graft material through the lumen of the handle and the tube by actuating the trigger to cause the ratcheting mechanism to distally advance the plunger.
14. The method of claim 13 , wherein loading the bone graft material comprises loading the bone graft material into the proximal opening.
15. The method of claim 13 , further comprising inserting a rasping instrument through the proximal opening and lumen of the handle and the tube and decorticating bone with the rasping instrument.
16. The method of claim 13 , further comprising decorticating bone with a tip at a distal end of the tube, the tip having at least one opening for delivering the bone graft material to the surgical location.
17. A bone graft delivery system, comprising:
an elongate tube;
a handle at a proximal end of the tube configured to be actuated to deliver bone graft material through the tube, the handle comprising:
a funnel at a proximal end of the handle, the funnel configured to receive bone graft material;
a channel extending between and in fluid communication with the funnel and the proximal end of the tube;
a ratcheting mechanism configured to advance bone graft material from the funnel, through the channel, and into the tube; and
a trigger configured to be actuated to deliver the bone graft material through the tube.
