  • Publication number: 20060149244
    Abstract: A device for connecting a longitudinal bar to a pedicle screw for fixation of the spine includes a body having an axis, an upper end, a lower end, a hole coaxial with the axis, and a through hole positioned perpendicular to the axis. The device also includes a collet chuck slidably disposed within the hole. The collet chuck includes a through hole substantially aligned with the through hole of the body for receiving the longitudinal bar. The collet chuck also includes a chamber defined by elastic tongues for receiving the head of the pedicle screw.

  • Patent number: 6520664
    Abstract: A colored luminaire, in particular a colored signaling light for automobiles, fitted with a lamp and a luminaire cover in which the lamp has a bulb with a coating of a first layer comprising a pigment, which pigment is chosen from the group of perylene pigments, perinone pigments, isoindoline pigments, and thioindigo pigments, is remarkable for a long useful life. It is not attacked by UV radiation, moisture, and spraying salt and is resistant to temperatures of between 250 and 350° C. Colored luminaires with bulb coatings comprising these pigments alone or in combination with further pigments for color correction comply with the color standards for automobile luminaires.

  • Publication number: 20030023240
    Abstract: The invention relates to a device for connecting a longitudinal bar to a pedicle screw thereby forming a system for fixation of the spine. The device includes a body having an upper end, a lower end, a hole which is open at least towards the bottom and has an axis, and a through hole positioned perpendicular to the axis. The device also has a collet chuck mounted coaxially on the inside of the body in such a way that it can slide along the axis. The collet chuck has a through hole which is flush with the through hole of the body, and a chamber which faces at least downwards and is defined by tongues spring-mounted against the cylinder axis. When the collect chuck is inserted in the body, the through holes align to allow insertion of the longitudinal bar. The head of a pedicle screw can be clicked into the chamber from below by spring-action. The device is easy to use and makes it possible for the pedicle screw to be inclined within a certain range.

  • Patent number: 5735852
    Abstract: The invention concerns a clamp for a spinal affixation device which has a base body (1) crossed by a duct (2) having a longitudinal axis (3) for receiving a longitudinal support. The clamp includes a substantially planar extension (4) continuing the base body (1) and crossed by a screw hole (5) having a center axis (6) for receiving a bone screw. The duct (2) can longitudinally and rotationally lock in place a longitudinal support which is inserted therein. The longitudinal axis (3) of the duct (2) and the center axis (6) of the screw hole (5) form skewed straight lines of constant spacing (7) at a distance in the range of 4 to 10 mm.

  • Patent number: 5534001
    Abstract: The osteosynthetic fixation element (10) in the form of a pedicular screw or a vertebral column hook has a lower section (2) that can be anchored into a bone and an upper section (3) connected in the direction of its longitudinal axis (1), that is completely penetrated transversely by a penetration channel (8) running transversely to the longitudinal axis (1) for acceptance of a longitudinal support (40). The upper section (3) is provided with an internal threading (5) and an external threading (9) to accept a locking part (30; 50) locking the longitudinal support (40). The upper section (3) is provided at its upper end (6) or at the inserted lock part (30; 50) with a rotationally-stable, releasable connecting mechanism (4, 5, 7; 11, 12) for positive and non-positive temporary acceptance of a manipulation device (20).
