    摘要： A nuclectomy method for creating a nuclear cavity in an annulus located in an intervertebral disc space and for preparing the nuclear cavity to receive an intervertebral prosthesis. The method involves identifying a plurality of regions in at least a portion of the nucleus. A sequence for removing the regions is also determined. At least one annulotomy is formed in the annulus along an annular axis to provide access to the nucleus. A guide system is positioned relative to the annulotomy. The guide system is configured to limit motion of at least one surgical tool relative to the guide system. A portion of the nucleus is removed from a first region using the surgical tool. At least one of the guide system and the surgical tool are configured to remove a portion of the nucleus from a second region. A portion of the nucleus is removed from a second region using the surgical tool.

    摘要： A device can be provided for pivoting a front hatch of a track-guided vehicle, which can a reduced weight, while at the same time being able to reduce susceptibility to failure. The device can include a first pivot lever connectable to the front hatch and a second pivot lever connectable to the front hatch, where the pivot levers can be rotatable about a common rotational axis, to pivot the front hatch relative the vehicle chassis. The device can also include a first actuating element connectable to the vehicle chassis which can interact with the first pivot lever. For example, upon the first actuating element being actuated, torque can be exerted on the first pivot lever. A second actuating element can be provided which is connectable to the vehicle chassis, and which interacts with the second pivot lever. Upon the second actuating element being actuated, torque can be exerted on the second pivot lever. The device can further include a synchronization element (e.g., in the form of a rod-shaped element) extending along the common rotational axis which is connected to the first pivot lever on the one side and to the second pivot lever on the other so as to synchronize the rotational movement of the pivot levers.
