Abstract
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.
Claims18
An kit for retraction and distraction of a spine, comprising:
- at least two spinal processes clamps, each clamp configured to attach to spinal processes of a spine, each spinal process clamp rotatably connected directly to a translation guide and comprising an interface for mating with a corresponding interface on a distraction tool;
- a retractor ring having two ends and a translation clamp secured directly to each end and slidably coupled to one of the translation guides and, the retractor ring couplable to and angularly adjustable with the spinal processes clamps;
- and
- at least one retractor blade couplable to the retractor ring.
A system for performing spinal retraction and distraction, the system comprising:
- at least two spinal processes clamps, each spinal processes clamp rotatably connected directly to a translation guide and comprising an interface for mating with a corresponding interface on a distraction tool, wherein each spinal processes clamp is secured to one or more spinal processes of a patient;
- a retractor ring having two ends and a translation clamp secured directly to each end and slidably coupled to one of the translation guides and thereby attached to the spinal processes clamps;
- at least one retractor blade coupled to the retractor ring and retracting soft tissue around the spinal processes to expose a spine segment;
- and
- a distraction tool comprising and interface coupled with the spinal processes clamp interface and applying a distracting force to the spinal segment.
