摘要： An apparatus is provided to hold and orient an implant during a medical procedure and includes an elongated member having an upper member and a lower member with a formed end. A biasing member is operatively positioned between the upper member and lower member and supplies a biasing force to the lower member. A ball joint is provided that includes a ball, and the ball joint accepts the formed end of the lower member. A biasing force is provided by the biasing member to cause the formed end of the lower member to contact the ball. A translation mechanism is used to move the upper member in a first linear direction toward the lower member to cause the formed end of the lower member to lock the ball of the ball joint and, thus, lock the ball joint and orient the ball of the ball joint in a desired position.

摘要： A method of securing vertebrae includes inserting a first pedicle screw into a first pedicle of a first vertebra. The first pedicle screw includes a first channel running perpendicular to a first central axis of the first pedicle screw. The first pedicle screw has a first engagement structure. The method further includes inserting a second pedicle screw into a second pedicle of a second vertebra. The second pedicle screw includes a second channel running perpendicular to a second central axis of the second pedicle screw. The second pedicle screw has a second engagement structure. The method also includes inserting a guidewire through the first and second channels, threading a tether attached to an end of the guidewire through the first and second channels, securing the tether to the first pedicle screw, applying tension to the tether, and securing the tether to the second pedicle screw.

摘要： This invention relates to an improved method and system for making relatively large and rapid adjustments in the process gas inventory of an electrically powered gaseous diffusion cascade in order to accommodate scheduled changes in the electrical power available for cascade operation. In the preferred form of the invention, the cascade is readied for a decrease in electrical input by simultaneously withdrawing substreams of the cascade B stream into respective process-gas-freezing and storage zones while decreasing the datum-pressure inputs to the positioning systems for the cascade control valves in proportion to the weight of process gas so removed. Consequently, the control valve positions are substantially unchanged by the reduction in invention, and there is minimal disturbance of the cascade isotopic gradient. The cascade is readied for restoration of the power cut by simultaneously evaporating the solids in the freezing zones to regenerate the process gas substreams and introducing them to the cascade A stream while increasing the aforementioned datum pressure inputs in proportion to the weight of process gas so returned. In the preferred form of the system for accomplishing these operations, heat exchangers are provided for freezing, storing, and evaporating the various substreams. Preferably, the heat exchangers are connected to use existing cascade auxilliary systems as a heat sink. A common control is employed to adjust and coordinate the necessary process gas transfers and datum pressure adjustments.
摘要翻译：本发明涉及一种改进的方法和系统，用于对电动气体扩散级联的工艺气体库存进行相当大的和快速的调整，以便适应可用于级联操作的电力的调度变化。在本发明的优选形式中，通过同时将级联B流的子流抽出到相应的过程气体冷冻和存储区域中，同时降低对于定位系统的基准压力输入，级联将被准备用于电输入的降低级联控制阀与工艺气体的重量成正比，如此去除。因此，通过本发明的减少，控制阀位置基本上不变，并且对级联同位素梯度的干扰最小。通过同时蒸发冷冻区中的固体来重新生成过程气体子流并将它们引入级联A流，同时增加与所回收的工艺气体重量成比例的上述基准压力输入，准备级联来恢复功率切断。在用于完成这些操作的系统的优选形式中，提供了用于冷冻，存储和蒸发各种子流的热交换器。优选地，热交换器被连接以使用现有的级联辅助系统作为散热器。采用通用控制来调节和协调必要的过程气体传输和基准压力调节。
