<p>Intramedullary bolted nail for use in member reconstructive therapy, where it has an anti-rotation design of a piston with a body of four faces two flat and two curves, a neck which is continuous with the body curved surfaces, a truncated cone (funnel) to facilitate the location of the thread, a smooth cylinder allows a correct angle to the axis of the screwdriver of the thread, and finally a thread that allows the rundown; a hollow female coupling end; (O-ring) sealing; and where the device has holes for bolting (anchored to the bone) on the flat side of the piston. Intramedullary bolted nail for use in member reconstructive therapy, where it has an anti-rotation design of a piston with a body of four faces two flat and two curves, a neck which is continuous with the body curved surfaces, while in the flat has a gradual increase in diameter that works as a stop when it reaches the diameter is the same with which is followed by a cylinder head which in turn has indentations where introduce two rubber rings (O-rings) and on top presents a rescue screw geometry is described as resulting from the sum ordered in three segments sense of insertion of the driver are: a truncated cone (funnel) to facilitate the location of the thread, a smooth cylinder allows a correct angle to the axis of the screwdriver of the thread, and finally a thread that allows the rundown; a hollow female coupling end of which fits on a reciprocal basis with the geometry of the body on which a telescoping anti-rotation and determine the cap on the neck; on the other female coupling end of a threaded coupling which tunneled partially introduced into the female coupler segment tunneled cylindrical outer diameter corresponds to the diameter tunneled internal female coupling and also presents a notch is inserted a rubber ring; (O-ring) sealing at the other end of this segment is attached a hose that connects to a threaded syringe; the device has holes for bolting (anchored to the bone) on the flat side of the piston in a part close to the female threaded coupling and telescoping tunneling coupling.</p> |
