Abstract
Disclosed herein are various tools and devices for use in spinal surgery. In one embodiment, a spinal guide device is provided having a guide member with a positioning element that is adapted to engage a portion of a vertebra to position the guide member relative to the vertebra. The guide member can also include a retractor guide that is adapted to guide a retractor therethrough to retract tissue adjacent to the distal end of the guide member. Various tissue retractors, bone preparation tools, and spinal implants are also disclosed.
Claims19
A spinal guide system, comprising:
- an elongate tube having opposed proximal and distal open ends;
- a positioning element extending distally from a sidewall of the distal end of the elongate tube, the positioning element having a distal end configured to engage a vertebra to position the elongate tube relative to the vertebra;
- and
- a c-shaped retractor guide with first and second terminal ends directly attached to opposite sides of the elongate tube, and with a mid-portion spaced radially outward from the elongate tube such that the retractor guide defines a pathway configured to slidably receive a retractor for retracting tissue adjacent the vertebra.
A spinal guide system, comprising:
- an elongate shaft having a handle coupled to a proximal end thereof and a guide member coupled to a distal end thereof, the guide member including
- an elongate tube having opposed proximal and distal ends with an inner lumen extending therebetween, the distal end of the elongate shaft being coupled to a sidewall of the elongate tube adjacent the proximal end of the elongate tube,
- a positioning element coupled to and extending distally beyond the distal end of the elongate tube, and
- a retractor guide coupled to the distal end of the elongate tube, the retractor guide defining an opening extending between the retractor guide and an exterior surface of a sidewall of the elongate tube, the opening being configured to slidably receive a retractor between the retractor guide and the exterior surface of the sidewall to retract tissue adjacent a vertebra engaged by the positioning element.
A spinal guide system, comprising:
- an elongate tube having opposed proximal and distal ends;
- a positioning element having a first end directly mated to a sidewall of the elongate tube and a second end extending distally beyond the distal end of the elongate tube;
- and
- a retractor guide extending between the elongate tube and the positioning element with a first terminal end of the retractor guide being attached to the positioning element and a second terminal end of the retractor guide being attached to the distal end of the elongate tube.
