摘要：
A spine retractor and distractor device comprises spinal process clamps and a retractor assembly, which may be rotatably coupled with the spinal process clamps. The retractor assembly may include a retractor ring, or frame, and a plurality of retractor blades adjustably coupled to the frame, e.g., by clamps. The spinal process clamps can maintain a grip on the spinal processes of the patient, and distraction pliers may be used to impart a distraction force on the spinal process clamps to distract the spinal segments. Additionally, other components, features, or tools, e.g., a light source and/or a camera, can be mounted on the instrument.
