    • Instruments and methods for creating an operative corridor to the spine and performing a spinal fusion. The instruments including, for example, a retractor assembly with a plurality of retractor blades, at least two pedicle screws, and a connecting rod. The retractor blades are coupled to the pedicle screws such that the operative corridor is registered to known anatomical landmarks aiding the surgeon with intraoperative orientation and anatomy identification. The retractor blades may be coupled to the pedicle screws via a polyaxial connection such that the angle of the operative corridor may be adjusted while maintaining the registration to the landmarks. Rod receivers may be attached to the pedicle screws after the disc space is operated on to minimize encumbrances on the working space within the operative corridor. A connecting rod is subsequently locked to the receivers to fix the spinal segment.
    • 用于创建脊柱的手术走廊和进行脊柱融合的仪器和方法。 所述仪器包括例如具有多个牵开器叶片的牵开器组件,至少两个椎弓根螺钉和连接杆。 牵开器叶片联接到椎弓根螺钉,使得手术走廊与已知的解剖学标记配准,帮助外科医生进行术中取向和解剖识别。 牵开器叶片可以经由多轴连接件联接到椎弓根螺钉,使得可以调节有效走廊的角度,同时保持与地标的对准。 在操作光盘空间之后,杆接收器可以附接到椎弓根螺钉上,以最小化操作走廊内的工作空间的负担。 连接杆随后被锁定到接收器以固定脊柱节段。
