    • A system and method are provided for making an access channel through a vertebral body to access a site of neural compression, decompressing it, and repairing the channel to restore vertebral integrity. System elements include an implantable vertebral plate, a guidance device for orienting bone cutting tools and controlling the path of a cutting tool, a bone cutting tool to make a channel in the vertebral body, a tool for opening or partially-resecting the posterior longitudinal ligament of the spine, a tool for retrieving a herniated disc, an implantable device with osteogenic material to fill the access channel, and a retention device that lockably-engages the bone plate to retain it in position after insertion. System elements may be included in a surgery to decompress an individual nerve root, the spinal cord, or the cauda equina when compressed, for example, by any of a herniated disc, an osteophyte, a thickened ligament arising from degenerative changes within the spine, a hematoma, or a tumor.
    • 提供了一种系统和方法,用于通过椎体进入通道以访问神经压缩部位,对其进行解压缩,以及修复通道以恢复脊椎完整性。 系统元件包括可植入椎板,用于定向骨切割工具并控制切割工具的路径的引导装置,用于在椎体中形成通道的骨切割工具,用于打开或部分切除后纵韧带的工具 的脊柱,用于回收突出的椎间盘的工具,具有成骨材料以填充进入通道的可植入装置,以及保持装置,其可锁定地接合骨板以在插入后将其保持在适当的位置。 系统元件可以被包括在手术中,以在压缩时例如通过脊髓中的退行性变化引起的任何突出的椎间盘,骨赘,增厚的韧带中的任何一个来减压单个神经根,脊髓或马尾, 血肿或肿瘤。

    • The invention relates generally to systems and methods for securing adjacent vertebrae in a fixed spacial relationship. In one embodiment, the system includes at least one interbody repair implant, at least one implantable vertebral frame and at least one retention member. In this embodiment, the interbody repair implant is sized to fit in an intervertebral space. The at least one implantable vertebral frame is configured to span between the adjacent vertebrae. The frame is also configured to attach to each of the adjacent vertebra to postoperatively maintain a desired spatial relationship between the vertebrae. The frame has at least one internal aperture there-through for providing visual access to at least a portion of the interbody repair implant, both intra-operatively and post-operatively. Methods of fusing two or more adjacent vertebral bodies in a portion of a spinal column are also disclosed. One such method includes the steps of inserting an interbody repair implant into a intervertebral space, securing an implantable vertebral fixation frame to the adjacent vertebral bodies over the implant, installing a retention member to the frame to cover at least a portion of the aperture, and moving a locking portion of the retention member from an unlocked position to a locked position.
    • 本发明一般涉及用于以固定的空间关系固定相邻椎骨的系统和方法。 在一个实施例中,系统包括至少一个椎间体修复植入物,至少一个可植入椎骨框架和至少一个保持构件。 在该实施例中,体内修复植入物的尺寸设置成适合于椎间空间。 所述至少一个可植入椎骨框架构造成跨越相邻椎骨之间。 框架还被配置为附接到每个相邻的椎骨以在术后保持椎骨之间期望的空间关系。 该框架具有至少一个内孔,用于在手术中和手术后两者中提供至少一部分体内修复植入物的视觉通路。 还公开了在脊柱的一部分中融合两个或更多个相邻椎体的方法。 一种这样的方法包括以下步骤:将椎间体修复植入物插入到椎间空间中,将可植入的椎骨固定框架固定在植入物上的相邻椎体上,将保持构件安装到框架以覆盖孔的至少一部分,以及 将保持构件的锁定部分从解锁位置移动到锁定位置。

    • The invention relates to a system and methods for retracting soft tissue during spinal repair or reconstruction procedures, particularly procedures within intervertebral sites of degenerated discs and associated neural compression. A retractor system includes an implantable bone plate, two or more retractor blades, the bone plate and retractor blades being mutually engageable; and a mechanism to adjust the retractor blade relative to the bone plate. In some embodiments, the retractor system may be applied to span more than one intervertebral space. An implanted retractor system provides an aperture for a clear operating field, and protects collateral tissue. A method for retracting soft tissue to facilitate spinal surgery includes securing a bone plate to adjacent vertebral bodies, engaging one or more retractor blades to the bone plate; and adjusting the angular position of the retractor blade relative to the bone plate so as to retract tissue lying external to the bone plate.
    • 本发明涉及一种用于在脊柱修复或重建过程中回缩软组织的系统和方法,特别是在退化椎间盘的椎间部位和相关联的神经压缩中的程序。 牵开器系统包括可植入骨板,两个或多个牵开器叶片,所述骨板和牵开器叶片可相互接合; 以及用于相对于骨板调节牵开器叶片的机构。 在一些实施例中,牵开器系统可以应用于跨越多于一个椎间空间。 植入式牵开器系统提供用于清晰操作区域的孔,并保护侧支组织。 一种用于缩回软组织以便于脊柱手术的方法包括将骨板固定到相邻的椎骨体上,将一个或多个牵开器叶片接合到骨板上; 以及调整牵开器叶片相对于骨板的角度位置,以便缩回位于骨板外部的组织。
