Abstract
A bone graft delivery system for delivering graft material into a surgical site. The delivery system includes an elongate hollow tube constructed to receive the bone graft material and having a hollow interior and indicia formed on an exterior surface of the elongate hollow tube. The delivery system also includes a plunger adapted to extend in the elongate hollow tube and to form a substantially congruent fit with the hollow interior of the elongate hollow tube such that the plunger is precluded from rotating within the elongate hollow tube. The plunger is adapted to urge bone graft material through the elongate hollow tube to deliver bone graft material through an opening thereof.
Claims20
A combination bone graft insertion and implant insertion apparatus comprising:
- a hollow tube constructed to receive bone graft, the hollow tube having a proximal end and a distal end, the hollow tube having an interior cross-section;
- an implant detachably connected to the distal end of the hollow tube, the implant having striations on a plurality of implant surfaces, the implant having a tapered distal end;
- a plunger having a distal tip and being adapted for inserting into the proximal end of the hollow tube, wherein the hollow tube, the implant and the plunger are configured to deliver bone graft material through the implant when the plunger is advanced through the hollow tube,
- wherein the hollow tube is configured so that the plunger is proximal to the distal end of the hollow tube when said plunger is inserted into said hollow tube;
- and
- a tool engaged with the hollow tube for detaching the implant.
A combination bone graft delivery and implant insertion apparatus for integrated delivery of bone graft material to a spinal surgical site and for disposing an implant to a spinal surgical site, comprising:
- a hollow tube constructed to receive bone graft, the hollow tube having a proximal end and a distal end;
- a substantially hollow implant for use in spinal surgery detachably connected to the distal end of the hollow tube, the implant constructed to receive bone graft from the hollow tube,
- the implant having striations and being configured to fit between a spinal disk space of a spinal surgical site, the implant having striations on a plurality of surfaces and having a tapered distal end;
- a plunger adapted for insertion into the hollow tube for delivering bone graft to an interior of the implant, wherein the hollow tube, the implant and the plunger are configured to deliver the bone graft material through an interior of the implant to the spinal surgical site;
- and
- a tool engaged with the hollow tube for detaching the implant.
