    摘要： A multi-axial bone fixation implant includes an elongated member, one or more bone anchor assemblies, and stabilizer members fitted within the elongated member. A bolt having a bone-threaded end and a machine-threaded end and an enlarged medial portion is also provided. The bolt is anchored into a bone, and its machine-threaded end passes through the elongated member and the stabilizer, and is engaged by a coupled washer and nut. The washer includes an oblong aperture, and the nut includes a projecting sleeve. The sleeve is inserted into the washer and expanded, and the washer retains the sleeve without impairing relative rotatability or translatability of the nut and washer. When locked by the nut and washer, the enlarged portion of the bolt is forced against the stabilizer, which locks against the elongated member. The elongated member can be fixed with respect to the anchor at an infinite number of multi-axial angles.

    摘要： A multi-axial bone fixation implant includes an elongated member, one or more bone anchor assemblies, and stabilizer members which are fitted within the elongated member. A bone bolt having cancellous threads on one end and machine threads at the opposing end and an enlarged portion between these sections is also provided. The bone bolt is anchored into a bone via the cancellous thread end. The machine threaded end passes through an opening of the elongated member and the stabilizer, and is engaged by a coupled washer and nut. The washer includes an undercut within its oblong aperture, and the nut includes a projecting sleeve. The sleeve is inserted into the washer aperture and expanded, so that the undercut retains the sleeve within the washer without impairing the rotatability or translatability of the nut and washer with respect to each other. When locked by the nut and washer atop the elongated member, the enlarged portion of the bolt is forced against an inside wall of the stabilizer, which is in turn locked against the elongated member. Accordingly, the elongated member is fixed with respect to the bone anchor at one of an infinite number of multi-axial angles.

    摘要： A spinal implant system is disclosed for the fixation of bone segments in the spine. The system includes an elongated member, one or more bone anchor assemblies, and stabilizer members which are fitted within the elongated member. A bone anchor is attached to a bone, and the elongated member and stabilizer are fitted over the bone anchor. A rounded washer and nut having a corresponding rounded underside surface are fitted on to the bone anchor over the elongated member, and tightened. The configuration of the bone anchor assembly, including an intermediate portion of the bone anchor, the arcuate washer, and the nut, along with the configuration of the sliding support, allows multi-axial positioning of the bone anchor with respect to the elongated member at a plurality of locations along a slotted member.

    摘要： Apparatus is disclosed for use in closing a medical device and preventing splaying of wall portions or legs of the medical device while maintaining low profile and minimal bulk of the medical device. The disclosed device is a medical device including a receiver member and a closure member. The receiver member includes an internal reverse angle thread, and the closure member includes an outer reverse angle thread, matable with the inner reverse angle thread. When the closure member is threaded into the receiver member, forces tending to splaying the wall portions or legs of the receiver member cause an interference fit between thread surfaces of the closure member and the receiver member, preventing the splay from occurring.

    摘要： An introduction apparatus for approximating a longitudinal member and an implant to permit fixation therebetween. The introduction apparatus having a gripping nose for securely engaging an implant, a lateral approximation mechanism for laterally aligning an implant and an offset longitudinal member, and a reduction mechanism for reducing the vertical distance between the implant and the longitudinal member. The introduction apparatus is provide with a gripping nose actuated by axial movement of a clamping shaft in an outer sleeve. The clamping shaft further includes an axial cannula for passage of a fastener to the implant.
