Bone graft dispensing device
View Patent ↗The present disclosure provides a device and method for applying a bone graft material to the body. The device includes a cylinder into which bone graft material is loaded. Specifically, the bone graft material is loaded into the cylinder through a funnel at a proximal end of the cylinder and dispensed through a tip at a distal end of the cylinder. After the bone graft material is loaded, a sleeve within the cylinder can be removed in order to create a channel within the bone graft material. Water or other hydrating fluid may be inserted into the channel through a port adjacent the proximal end of the cylinder in order to hydrate the bone graft material.
1. A method for dispensing bone graft material, the method comprising:
providing a bone graft dispensing device including
a cylinder including a funnel at a proximal end and a dispensing tip at a distal end, and
a removable sleeve positioned within the cylinder;
adding a bone graft material into the cylinder via the funnel;
removing the removable sleeve from the cylinder, wherein the removal of the sleeve forms a channel within the bone graft material;
adding a hydrating fluid into the channel to form a hydrated bone graft material;
positioning a plunger within an interior of the cylinder, wherein the plunger is positioned within an opening in a cap, wherein the cap is positioned within the funnel of the cylinder, wherein the plunger is movable along a central axis within the interior of the cylinder, wherein the cap includes a cylindrical opening; and
depressing the plunger through the cylinder toward the distal end of the cylinder, wherein the depression of the plunger releases the hydrated bone graft material through the dispensing tip.
2. The method of claim 1 , wherein the cylinder includes a protrusion extending outwardly from the central axis adjacent to the distal end.
3. The method of claim 1 , wherein the cylinder includes a port extending outwardly from the central axis, wherein the hydrating fluid is added to the channel via the port, wherein the port is in fluid communication with the interior of the cylinder.
4. The method of claim 1 , wherein the cap is threadably engaged with an interior of the funnel of the cylinder.
5. The method of claim 1 , further comprising a port extending outwardly from the central axis, wherein the port is in fluid communication with the interior of the cylinder, wherein the removable sleeve is positioned within the cylinder and extends out of the port.
6. The method of claim 1 , further comprising a handle extending from the cap.
