  • Patent number: 5690842
    Abstract: A method of manufacturing a strong orthopaedic wire (30). A block (20) has an opening (26) with an interior diameter which is slightly larger than an outside diameter (28) of the wire (30). The wire (30) is placed within the opening (26) such that an end (36) of the wire (30) extends a predetermined distance (40) above the block (20). The extending end (36) is heated (e.g. by applying an electric current) until the metal from which the wire is made reaches the wire melting point. The molten metal is allowed to fall via gravitational force against the block (20), whereby the extending end (36) forms an enlarged end (42) on the wire (30).

  • Patent number: 5649931
    Abstract: The invention is directed to an orthopaedic apparatus 10 for at least one of removing and driving an elongated fixation member 12 having an enlarged head 22. The orthopaedic apparatus 10 includes a hollow, elongated body 14 having an open end 26 for receiving the enlarged head 22 therein. The body 14 further has a deflectable portion 28 at the open end. A shaft 16 is disposed within the body, and has a distal end 34 disposed substantially adjacent to the body open end. The distal end 34 has an exterior configuration which is adapted to mate with the enlarged head. The deflectable portion is configured to impart a radially inward force around the enlarged head and the shaft is configured to impart an axial compression force on the enlarged head, thereby locking the elongated fixation member relative to the orthopaedic apparatus.
