20110034955 | CONNECTOR - A connector for vertebra connection members that connect a plurality of vertebrae via a rod includes: a connector body that has formed therein a rod orifice into which the rod is inserted, a fixing member orifice into which a fixing member that fixes the rod inserted into the rod orifice is screwed, and a screw member orifice into which a screw member to be screwed into the vertebra is inserted, and that connects the rod and the screw member to be screwed into the vertebra; and a diameter adjusting member that is inserted into the rod orifice and has formed therein a convex curved surface that abuts against the rod orifice and a concave curved surface that abuts against the rod. The screw member is inserted into the screw member orifice and fixed to the connector, and the rod is inserted into the rod orifice into which the diameter adjusting member has been inserted and is fixed to the connector. | 02-10-2011 |
20090204214 | CAGE - A cage interposed between a pair of vertebral bodies, wherein both left and right side surfaces of a cage body are formed in a smooth surface, both upper and lower surfaces of the cage body are provided with a large number of projections arranged in a longitudinal direction and a lateral direction, tip end surfaces of the large number of projections substantially match with a virtual arc curved surface formed around an axis in the longitudinal direction, and angles of inner end edges of the projections close to left and right side surfaces are more acute. A longitudinal through hole is formed in the cage body in its longitudinal direction so as to penetrate the cage body, and both left and right side surfaces and both upper and lower surfaces of the cage body are provided with communication holes which are in communication with the longitudinal through hole. The communication holes are circular holes having a common diameter. | 08-13-2009 |
20090204153 | ROD CONNECTOR - A rod connector for connecting, to each other, opposed ends of a plurality of rods held by a rod holding tool which is fixed to a vertebra, wherein a cylindrically formed connector body is previously curved or bent according to a curve of the vertebral column constructed by the vertebra, both ends of the connector body are provided with a rod insertion hole, rod insertion openings into which the rods are inserted are formed in both end surfaces of the connector body, and the connector body includes screw holes through which fixing screws are threadedly inserted for fixing the rods inserted into the rod insertion hole. | 08-13-2009 |
20090125065 | Vertebra connection member and nut driver - A vertebra connection member has: a screw member that is screwed in a vertebra; a connector member that connects a rod and the screw member; a first nut member that fixes the screw member and connector member; a second nut member that prevents the loosening of the first nut member; and a fixing member that fixes the rod and connector member. The first and second nut members are formed to have a cylindrical shape; and engagement concave portions of a concave curved shape are formed in the outer peripheral surface of the nut members from the rear ends in the screw-in direction to the front ends in the screw-in direction, in the direction in which the nut members are screwed onto the second male portion. | 05-14-2009 |
20090043338 | VERTEBRA CONNECTION MEMBER AND NUT DRIVER - A vertebra connection member has: a screw member that is screwed in a vertebra; a connector member that connects a rod and the screw member; a first nut member that fixes the screw member and connector member; a second nut member that prevents the loosening of the first nut member; and a fixing member that fixes the rod and connector member. The first and second nut members are formed to have a cylindrical shape; and engagement concave portions of a concave curved shape are formed in the outer peripheral surface of the nut members from the rear ends in the screw-in direction to the front ends in the screw-in direction, in the direction in which the nut members are screwed onto the second male portion. | 02-12-2009 |
