摘要： A bone fixation system for locking a longitudinal member, such as a spinal rod, to a bone anchor element allowing a variable orientation of the axis of the longitudinal member relative to the axis of the bone anchor. A one-piece body element split along a substantially horizontal plane into upper and low er portions by a slot includes a ball element through which a longitudinal member, such as a spinal rod, may pass. A portion of a bone anchor element passes through an aperture having portions on each of the upper and lower portions of the body element. Tightening a set screw draws the upper and low er portions of the body element together and locks the bone anchor and spinal r od into the desired position.

摘要： A double-jointed bone bolt for use in an apparatus for maintaining vertebra in a desired relationship. The apparatus has a rod that extends substantially along the spine and one or more bone bolts. At least one of the bone bolts is double jointed. The double-jointed bolt has a mounting portion with a hook or coarse threads to engage a vertebra, and the mounting portion is attached to a pivot post in a manner that allows the pivot post to be rotatable about a common axis in respect to the mounting portion. The pivot post of the bone bolt is then pivotally attached to a connector portion of the bone bolt that has machine threads upon which a surgeon may attach a clamp. The clamp has a second bolt and an arm. The second bolt holds the rod and the arm to the clamp. The second bolt has a first channel to attach to the rod, while the arm has a second channel to attach the double-jointed bone bolt.

摘要： A variable angle connection between a spinal rod and a vertebral anchor with a clevis to attach to the vertebral anchor, permitting the vertebral anchor to be longitudinally offset from the connecting point on the rod. The connection assembly has a bolt with a stop disposed near one end of the bolt and an aperture for receiving a portion of the spinal implant rod at the other end. The assembly also has a clevis. The clevis defines a bore to hold a portion of the vertebral anchor and the ears of the clevis have holes through which the bolt is located with the ears positioned between the stop and aperture of the bolt. The assembly also has a rod interface washer positioned over a portion of the bolt, between the aperture of the bolt and the inside ear of the clevis. The rod interface washer is partly movable between the aperture of the bolt and the clevis, but the washer is fixed against rotating in relation to the bolt. Finally, the assembly also includes a screw that is threads into the side of the bolt and continues into the aperture of the bolt. The screw is used to push the rod toward the vertebral anchor so that the inside and outside ears of said clevis are pressed together and the clevis is tightened the vertebral anchor.

摘要： Apparatus is disclosed for use in closing a medical device (10) and preventi ng splaying of wall portions or legs (20) of the medical device (10) while maintaining low profile and minimal bulk of the medical device (10). The disclosed device is a medical device (10) including a receiver member (11) a nd a closure member (12). The receiver member (11) includes an internal reverse angle thread (44), and the closure member (12) includes an outer reverse ang le thread (46), matable with the inner reverse angle thread (44). When the closure member (12) is threaded into the receiver member (11), forces tendin g to splay the wall portions or legs (20) of the receiver member (11) cause an interference fit between thread surfaces of the closure member and the receiver member, preventing the splay from occurring.

摘要： A variable angle connection (1) between a spinal rod (A) and a vertebral anchor (B) with a clevis (3) to attach to the vertebral anchor, permitting the vertebral anchor to be longitudinally offset from the connecting point on the rod. The connection assembly has a bolt (2) with a stop (10) disposed near one end of the bolt and an aperture (6) for receiving a portion of the spinal implant rod at the other end. The assembly also has a clevis. The clevis defines a bore (7) to hold a portion of the vertebral anchor and the ears (8, 9) of the clevis have holes through which the bolt is located with the ears positioned between the stop and aperture of the bolt. The assembly also has a rod interface washer (4) positioned over a portion of the bolt, between the aperture of the bolt and the inside ear of the clevis. The rod interface washer is partly movable between the aperture of the bolt and the clevis. but the washer is fixed against rotating in relation to the bolt. Finally, the assembly also includes a screw (15) that threads into the side of the bolt and continues into the aperture of the bolt. The screw is used to push the rod toward the vertebral anchor so that the inside and outside ears of said clevis are pressed together and the clevis is tightened around the vertebral anchor.

摘要： Un ensamblaje de acoplamiento (1) entre una varilla de implante espinal y un ancla vertebral; el ensamblaje comprende: (a) una pieza longitudinal (2) . Esta pieza longitudinal tiene una zapata (9) dispuesta cerca de un extremo de la pieza longitudinal y una abertura (6) para recibir una parte de la varilla de implante espinal (A) cerca del extremo opuesto de la pieza longitudinal; (b) una caja (3). Esta caja tiene un primer lado (21), un segundo lado (22) y una arista lateral (23) y tiene un pasadizo (8) que se abre hacia la arista lateral para recibir una parte del ancla vertebral (B); el pasadizo tiene una pared interna. Dicha caja tiene una superficie interior (17) que se abre hacia el primer lado para recibir por lo menos una parte de la zapata de dicha pieza longitudinal; dicha caja es movible parcialmente sobre al menos una parte de la zapata de dicha pieza longitudinal y el pasadizo (8) se abre más hacia la superficie interior (17); (c) una arandela de acoplamiento de varilla (4). Esta arandela de acoplamiento de varilla está posicionada sobre una parte de la pieza longitudinal (2) entre la abertura de dicha pieza longitudinal y el primer lado de dicha caja; dicha arandela de acoplamiento de varilla es movible parcialmente entre la abertura de dicha pieza longitudinal y dicha caja y está fijada contra la rotación relativa a dicha pieza longitudinal (2); (d) una pieza comprimida (5). Esta pieza comprimida está acoplada forzadamente a dicha pieza longitudinal para empujar la varilla contra el ancla vertebral, por lo que la zapata (9) se desplazará en la superficie interior (17) para empujar el ancla vertebral hacia la pared interna del pasadizo de dicha caja, y por lo que dicha caja y dicha arandela de acoplamiento de varilla se comprimirán.
