摘要：
Devices and methods for removing a spinal disc are provided herein. Discectomy instruments are disclosed that can remove a spinal disc in a single-pass, i.e., without repeatedly inserting and removing the instrument from a patient. In an exemplary embodiment, the discectomy instrument includes a distal housing, at least one cutting blade, and a handle. When the distal housing is positioned adjacent to a spinal disc, a handle can be actuated to advance the cutting blade along a substantially arc-shaped path through the disc. In certain aspects, the path of the blade can correspond to the anatomy of the disc and to the approach used to access the spine. A second cutting blade can be advanced through the disc and can intersect with the arc-shaped path, forming a complete cut. The cut disc can be received in the distal housing and removed from the patient.
