    摘要: A retractor may be used during spinal surgery. The retractor may include a frame and one or more retractor blades. Each retractor blade may include a coupling arm, a retainer, and a retraction component. The coupling arms may be coupled to the frame such that the coupling arms are able to move inward or outwards relative to the frame. The retainer may secure the retraction component to the coupling arm. In some embodiments, the retraction blades may be made of a radiolucent material that allows radiological images to be taken during a surgical procedure with the retractor in place. A position of retraction components relative to the frame may be changed during a surgical procedure. One or more of the retraction components may be replaced during a surgical procedure without removing the retractor from the patient.

    摘要: Embodiments disclosed herein provide compression/distraction methods and tools useful for fitting a spinal stabilization system in a patient through minimally invasive surgery. The spinal stabilization system may comprise screws anchored in vertebrae. The vertebrae may need to be compressed or distracted. One embodiment of an instrument disclosed herein may comprise a shaft for engaging one of the screws through an extender sleeve. A driver may engage another screw through an opening of the instrument. Through this engagement, a surgeon may use the rack and pinion of the instrument to compress or distract one or more levels of the vertebrae in a parallel motion, which can be advantageous clinically in certain situations.
