Abstract: A sternum suturing staple, comprising a central body (1) having at least two threaded portions (2, 2?) with opposite threads; two side members (6) each having a threaded part (7) adapted to couple to one of the central body threaded parts, and a claw (8) adapted to be located laterally to a sternum in an intercostal space, and in which the claws are adapted to cooperatively clamp the sternum so as to suture it, characterized in that the part or portion bearing the male thread has, adjacent and coaxial relative to said male thread, a non-threaded cylindrical stem length (5, 5?), while the part or portion bearing the female thread has, adjacent and coaxial relative to said female thread, a non-threaded cylindrical hole length (18) adapted to receive said stem length.

Abstract: A sternum suturing staple, comprising a central body (1) having at least two externally threaded portions (2, 2?) with opposite threads and at least two side members (6, 6?) each having a threaded part (5, 5?) adapted to be coupled with one of the threaded parts of the central body and a jaw (8, 8?) adapted to be positioned laterally to a sternum, previously subjected to a medial incision, and wherein the jaws are adapted to cooperatively tighten the sternum so as to suture it. It is also described an apparatus adapted to position and tighten said staple.

Abstract: A staple for the suture of the sternum having a central body with right and left threaded ends in which two teeth are screwed able to be introduced into suitable holes made astride a median sternotomy performed on a patient. Rotating the central body draws the teeth together or apart, thus tightening the two halves of the sternum with appropriate tension. The staple is suitable to be tightened by means of an apparatus provided with friction, to give the correct tightening tension. Also described are a method for the suture of the sternum and punch cutter forceps suitable to be used in such operation.
