Abstract
A spinal surgery retractor and method of use. The retractor includes a slotted keyway for integrating a keyed spinal distractor. The retractor and distractor combination slide together to displace a portion of the intervertebral disk space to restore or maintain intervertebral spacing and facilitate retraction of surrounding soft tissues while disk space surgery is performed. The distractor head and mating portion of the retractors have matching profiles that enable the retractor to maintain distraction of the vertebra after removal of the distractor portion of the tool, permitting access to increase at the operating site.
Claims19
A distractor retractor assembly, the assembly comprising:
- a distractor rod secured to a proximal end of a distractor head, wherein a distal end of the distractor head has a tapered profile between the distal end and the proximal end constructed and configured for insertion between adjacent vertebral bodies, the distal head includes a plurality of side faces positioned between the distal end and the proximal end, and a keyed shaped projection is secured to one of the side faces,
- wherein the distractor head is engaged on a distal tip of a retractor, the distal tip being constructed and configured for insertion between adjacent vertebral bodies, the distal tip of the retractor including a keyway having a beveled shape and the keyed shaped projection of the distractor head has a profile which is constructed and arranged to engage and cooperate with the keyway to operatively connect the distractor head to the retractor.
A distractor retractor assembly in spinal surgery, the assembly comprising:
- a distractor retractor assembly including a distractor portion and a retractor portion, the distractor portion including a distractor head and a distractor rod, the distractor head having a distal end and a proximal end, a keyed shaped projection secured to the distractor retractor assembly, a distal tip of the retractor portion including a keyway having a beveled shape, the keyed shaped projection of the distractor head having a profile which is constructed and arranged to engage and cooperate with the keyway to operatively connect the distractor retractor assembly between adjacent verterbral bodies, wherein
- the distractor retractor assembly is configured and dimensioned to be inserted into a disc space between adjacent vertebral bodies.
A distractor retractor assembly for use in spinal surgery, the assembly comprising:
- a distractor rod secured to a proximal end of a distractor head, wherein a distal end of the distractor head has a tapered profile between the distal end and the proximal end constructed and arranged for insertion between adjacent vertebral bodies, the distal head includes a plurality of side faces positioned between the distal end and the proximal end, and a keyed shaped projection is secured to one of the side faces,
- wherein the distractor head is engaged on a distal tip of a retractor, the distal tip being constructed and arranged for insertion between adjacent vertebral bodies, the distal tip of the retractor including a keyway having a beveled shape and the keyed shaped projection of the distractor head has a profile which is constructed and arranged to engage and cooperate with the keyway to operatively connect the distractor head to the retractor;
- and
- wherein the distractor head if configured and dimensioned to be inserted into a disc space between adjacent vertebral bodies.
