An injector device for percutaneously injecting biomaterial in the form of particles of different sizes or in the form of paste includes a trocar () of generally cylindrical shape presenting a open first end with a sharp edge, the wall of the first end presenting at least one orifice () for passing the biomaterial, and a second end () that is likewise open; a reservoir () for receiving the biomaterial, the reservoir including a part () of substantially cylindrical shape having two open ends, the cylindrical part being capable of being inserted at least in a portion of the trocar via the second end thereof; removable plugs for closing both ends of the reservoir; and a piston () insertable in the cylindrical part when the plugs are removed, the piston being capable of sliding in the cylindrical part and in the first end of the trocar.

Syringe for biomaterial

A device for delivering small spheres of biomaterial into a determined portion of a bone including a cylindrical hollow body of inside diameter Dhaving a filling first end and a second end provided with a snap-fastener, a shutter-forming guide rod having a main portion that is cylindrical with an outside diameter Dand presenting an enlarged cylindrical portion suitable for co-operating with the snap-fastener of the body, and a piston constituted by a cylindrical part presenting an outside diameter Dand an axial bore of diameter D. The diameter Dis slightly smaller than the inside diameter Dof the body and the inside diameter Dis slightly greater than the diameter Dof the rod in such a manner that, once the snap-fastener has been released, the rod can slide inside the piston, and the piston can slide inside the body.
