  • Patent number: 11478284
    Abstract: A surgical repositioning instrument for lowering and fixing a fixing rod in the tulip head of a bone screw has a coupling sleeve with two distal latching arms. A locking sleeve is longitudinally displaceable on the coupling sleeve between a release and locking position. A rod presser contacts and lowers the fixing rod, which is arranged displaceably within the coupling sleeve. Arranged in a through bore in the handle part is the locking sleeve, coupling sleeve and rod presser. On a grip part, an actuating lever is pivotally mounted to advance the rod presser relative to the coupling sleeve. The actuating lever has a laterally projecting force arm and a load arm which is coupled to the rod presser. The locking sleeve protrudes in its release position and is independently slid into its locking position by the rod presser acting on its proximal end with an axially directed force.

  • Patent number: 11471304
    Abstract: A surgical cage positioning system for the implantological replacement of an intervertebral disk, in the region of the lumbar spine of humans, has a positioning instrument with a first coupling prong and with a first manipulator prong, each provided with a coupling element. The manipulator prong can be displaced in the axial direction relative to the coupling prong by means of a handle. The cage positioning system has a cage with an insertion opening for the instrumentation segment and with coupling means, via which the coupling elements of the instrumentation segment, each pivotally connected to the cage, can be coupled so that the cage can be pivoted by means of the manipulator prong about an axis of rotation defined by the coupling element of the coupling prong and the coupling means of the cage relative to the longitudinal axis of the positioning instrument.

  • Patent number: 9066814
    Abstract: An implant assembly includes an implant having an upper element and a lower element coaxially aligned with one another. The upper and lower elements are configured to be displaced relative to one another along a longitudinal axis of the implant. The implant assembly also includes a setting tool having a cassette and a tool body. The cassette has a housing, a gear held by the housing, and a drive shaft driving the gear. The cassette holds the implant such that the gear engages the implant to displace the upper and lower elements relative to one another. The tool body has an inner portion and an outer portion being angled relative to one another. The cassette is mounted to the inner portion. The tool body has an outer shaft and an inner shaft rotatable received in the outer shaft. The inner shaft includes a flexible joint at the intersection of the inner and outer portions. The inner shaft drives the drive shaft of the cassette.
