Patent number: 6248104Abstract: This instrumentation comprises at least one vertebral rod (1), bone anchoring elements (2) spaced along the rod, a connector (3) connecting the rod to each anchoring element, and pressure means (4) for clamping together the rod, the anchoring element and the connector; each anchoring element has a bearing surface (7) for the rod which is inclined relative to the longitudinal axis (XX) of the anchoring element; in the connector there is provided a cavity (11) providing at least one bearing point for the rod held trapped between said inclined bearing surface and a wall (12) of the cavity, and the latter is extended by a lateral aperture (18) permitting insertion of the vertebral rod radially in its cavity; this instrumentation is easy to use by the surgeon owing to the convenience of insertion of the rod in the connector, and the direct bearing of the rod against the surface (7) of the anchoring element (2) reduces its transverse overall size.Type: GrantFiled: May 8, 2000Date of Patent: June 19, 2001Inventors: Daniel Chopin, Pierre Roussouly, Arsene Grosse, Gilbert Taglang, Jean Moulin, Jean Saurat

Patent number: 5810817Abstract: An apparatus including vertebral anchoring elements, such as a bone screw (1) or a hook (2), with a threaded cylindrical portion (5) and a locking plate (7). A nut (8) may be screwed onto the threaded cylindrical portion (5) to tighten the tightening portion of a slide (4) on a rigid connecting rod (3) with a circular cross-section. The rod (3), the slide (4) and the anchoring element (1,2) may be sufficiently rigidly connected by means of non-slip projections on the engaged side of the locking plate (7), on the corresponding side of the slide (4), and on the surface thereof which surrounds the rod (3). The stiffness of the apparatus may thus be enhanced, so that improved support of the vertebrae and easier fitting and adjustment of the apparatus may be achieved.Type: GrantFiled: May 23, 1997Date of Patent: September 22, 1998Inventors: Pierre Roussouly, Gilbert Taglang, Arsene Grosse, Daniel Chopin

Patent number: 5810816Abstract: The stabilizing device can be adapted to an anchor such as a hook (1) of the usual shape, with a hook body (4) and an incurved lug (7). The device including a stabilizing staple fastener (3) having a body (21) and staple legs (22-25). Said fastener body (21) is adapted so that the securing member secure the hook (1) to an attachment rod (52) also attach the fastener (3) to the hook (1), by forcing back the legs (22-25) in the direction of the incurved lug (7) so as to pierce a portion of the vertebra located in the hollow of the hook (1). The hook (1) is thereby effectively stabilized on the vertebra.Type: GrantFiled: October 9, 1996Date of Patent: September 22, 1998Inventors: Pierre Roussouly, Gilbert Taglang, Arsene Grosse, Daniel Chopin

Patent number: 5133717Abstract: A sacral support saddle has an eye (36) for receiving a first screw (38) and a cylindrical hole (37) with an axis (X5) of inclination such that, when the saddle (29) is positioned on the sacrum, the screw (38) is inserted into the sacral plate and towards the upper axis of the latter. A U-shaped body (32) delimits a channel (34) for receiving a rod, and a stopper (7) locks the rod (8) in this body. A hole (33) for passage of a second screw (42) has an axis (Y5) divergent relative to the axis (X5) of the hole of the eye in such a way as to be oriented towards the iliac mass when the saddle is positioned on the sacrum. This saddle and its two screws (38, 42) provide for a reliable anchoring of the rod of the device to the sacrum by virtue of the penetration of the screws into solid regions of the latter. This, in practice, avoids any risk of pulling out and, consequently, a second surgical intervention.Type: GrantFiled: February 7, 1991Date of Patent: July 28, 1992Assignee: Societe de Fabrication de Material Orthopedique SofamorInventor: Daniel Chopin
