    • A dynamic rod implantable into a patient and connectable between two vertebral anchors in adjacent vertebral bodies is provided. The rod fixes the adjacent vertebral bodies dynamically providing immediate postoperative stability and support of the spine. The rod comprises a first rod portion having a first engaging portion connected to a second rod portion having a second engaging portion. The rod includes at least a one bias element configured to bias a deflection or translation of the first rod portion relative to the second rod portion. The first engaging portion includes at least one side or integral spring formed in the first engaging portion to bias a deflection of the second rod portion relative to the first rod portion. The rod permits relative movement of the first and second rod portions allowing the rod to carry some of the natural flexion and extension moments that the spine is subject to.
    • 提供了一种可植入患者并可连接在相邻椎体内的两个椎骨锚之间的动态杆。 该杆动态地固定相邻的椎体,为脊柱提供即时的术后稳定性和支撑。 该杆包括第一杆部分,该第一杆部分具有连接到具有第二接合部分的第二杆部分的第一接合部分。 该杆包括至少一个偏置元件,该偏置元件被配置为偏置第一杆部分相对于第二杆部分的偏转或平移。 第一接合部分包括形成在第一接合部分中的至少一个侧面或一体式弹簧,以偏压第二杆部分相对于第一杆部分的偏转。 杆允许第一和第二杆部分的相对运动,从而允许杆承载脊柱所经受的一些自然的弯曲和伸展力矩。

    • A dynamic rod implantable into a patient and connectable between two vertebral anchors in adjacent vertebral bodies is provided. The dynamic rod fixes the vertebral bodies together in a dynamic fashion providing immediate postoperative stability and support of the spine. The dynamic rod comprises a first rod portion and a second rod portion connected together. The dynamic rod further includes at least a one bias element configured to provide a bias force in response to deflection or translation of the first rod portion relative to the second rod portion. The dynamic rod includes a locking construct which advantageously enables the extension and/or angulation of one rod portion with respect to the other rod portion to be reversibly locked in position. The dynamic rod permits relative movement of the first and second rod portions allowing the rod to carry some of the natural flexion and extension moments of the spine.
    • 提供了植入患者体内并可在相邻椎体内的两个椎骨锚固件之间连接的动态杆。 动态杆将椎体以动态方式固定在一起,提供立即术后稳定性和支撑脊柱。 动态杆包括连接在一起的第一杆部分和第二杆部分。 动态杆还包括至少一个偏置元件,其构造成响应于第一杆部分相对于第二杆部分的偏转或平移而提供偏置力。 动态杆包括锁定构造,其有利地使得一个杆部分相对于另一个杆部分的延伸和/或成角可逆地锁定在适当位置。 动态杆允许第一和第二杆部分的相对运动,允许杆承载脊柱的一些自然弯曲和伸展力矩。

    • A percutaneous and minimally invasive instrument system for implanting an interspinous process spacer into a patient is disclosed. The insertion instrument system includes an inserter and a driver. The inserter is configured to releasably clamp to an interspinous process spacer for its delivery, implantation and deployment. The driver is configured for removable insertion into a proximal end of a passageway of the inserter. The driver has a distal spacer engaging portion configured to engage that part of the spacer requiring activation for the deployment of the spacer from at least one undeployed configuration to at least one deployed configuration and vice versa. As the spacer goes from the undeployed to the deployed configuration and vice versa, the system advantageously provides a degree of deployment information to the user via at least one deployment indicator.
    • 公开了一种用于将棘突间间隔物植入患者体内的经皮和微创手术系统。 插入仪器系统包括插入器和驱动器。 插入器构造成可释放地夹紧到棘突间间隔件用于其递送,植入和展开。 驱动器被配置为可移除地插入到插入器的通道的近端中。 驱动器具有远侧间隔件接合部分,其构造成接合需要激活的间隔件的该部分以将间隔件从至少一个未部署构造部署到至少一个部署构造,反之亦然。 当间隔物从未部署到部署配置并且反之亦然时,系统有利地通过至少一个部署指示器向用户提供一定程度的部署信息。

    • A percutaneous and minimally invasive instrument for inserting an interspinous process spacer into a patient is disclosed. The instrument includes a first assembly connected to a handle assembly. The first assembly includes an inner shaft located inside an outer shaft and configured for translational motion with respect to the outer shaft. The relative translational motion causes one of the outer or inner shafts to move with respect to the other and thereby deflect at least one prong formed on one of the inner or outer shafts wherein such deflection causes engagement with a juxtapositioned interspinous spacer. The instrument further includes a driver configured for removable insertion into a proximal end of a passageway of the instrument. The driver has a distal spacer engaging portion configured to engage that part of the spacer requiring activation for deployment of the spacer from an undeployed configuration to a deployed configuration and vice versa.
    • 公开了一种用于将棘突间间隔物插入患者的经皮且微创的器械。 该仪器包括连接到手柄组件的第一组件。 第一组件包括内轴,该内轴位于外轴的内部并且被配置为相对于外轴平移运动。 相对平移运动导致外轴或内轴中的一个相对于另一个移动,并由此偏转形成在内轴或外轴中的一个上的至少一个叉,其中这种偏转导致与并置的棘突间间隔物接合。 器械还包括构造成可移除地插入器械的通道的近端中的驱动器。 驱动器具有远端间隔件接合部分,该远端间隔件接合部分配置成接合需要激活的间隔件的该部分以将间隔件从未展开构型展开到展开构型,反之亦然。
