System and method for percutaneous spine fusion
The present disclosure provides a retractor including an enclosure extending from a first open end to a second open end to form a lumen extending along an axis therebetween and that is accessible from the first open end and the second open end. The retractor further includes a first aperture formed at first angular position in the enclosure, and a second aperture formed at second angular position in the enclosure and opposing the first aperture to form a passage extending transverse to the axis from the first aperture, through the lumen, and to the second aperture. The first aperture and the second aperture are located proximate to the first open end and sized to arrange the passage along a spine of a patient to receive a trocar for delivering a graft material to the spine.
1. A kit for delivering graft material to a spine of a patient, comprising:
at least one retractor for insertion in an incision proximal to a spine of a patient, the retractor including:
an enclosure extending from a first open end to a second open end to form a lumen extending along an axis therebetween;
a first aperture formed in the enclosure at a first angular position in the enclosure; and
a second aperture formed in the enclosure at a second angular position in the enclosure and opposing the first aperture to form a passage from the first aperture, through the lumen, and to the second aperture; and
a trocar for delivering a graft material to the spine of the patient, the trocar including an elongated rod having a first open end and defining an interior space for receiving the graft material, the interior space extending along a longitudinal axis defined by the elongated rod,
wherein the first and second apertures are dimensioned to receive the elongated rod of the trocar such that the elongated rod extends through the passage and the longitudinal axis defined by the elongated rod is arranged transverse to the axis defined by the enclosure to arrange the graft material along the spine of the patient.
2. The device of claim 1 , wherein the first aperture and the second aperture extend in a longitudinal direction transverse to the axis extending along the enclosure from the first open end to the second open end.
3. The device claim 2 , wherein the first aperture and the second aperture are one of U-shaped and semi-circular shaped.
4. The device of claim 1 , wherein the first open end of the retractor is sized to be receivable within the incision in the patient to be arranged proximate to the spine.
5. The device of claim 1 , wherein the first angular position is 180 degrees from the second angular position.
6. The device of claim 1 , wherein the enclosure defines a generally cylindrical body.
7. The device of claim 1 , wherein the trocar has an angle of curvature.
8. A system for delivering graft material to a spine of a patient, comprising:
at least one retractor for insertion in an incision proximal to a spine of a patient, the retractor including:
an enclosure extending from a first open end to a second open end to form a lumen extending along an axis therebetween;
a first aperture formed in the enclosure at a first angular position in the enclosure; and
a second aperture formed in the enclosure at a second angular position in the enclosure and opposing the first aperture to form a passage from the first aperture, through the lumen, and to the second aperture; and
a trocar for delivering a graft material to the spine of the patient, the trocar including an elongated rod having a first open end and defining an interior space for receiving the graft material, the interior space extending along a longitudinal axis defined by the elongated rod,
wherein the first and second apertures are dimensioned to receive the elongated rod of the trocar such that the elongated rod extends through the passage and the longitudinal axis defined by the elongated rod is arranged transverse to the axis defined by the enclosure to arrange the graft material along the spine of the patient.
9. The system of claim 8 , wherein the first aperture and the second aperture extend in a longitudinal direction transverse to the axis extending along the enclosure from the first open end to the second open end.
10. The system claim 9 , wherein the first aperture and the second aperture are one of U-shaped and semi-circular shaped.
11. The system of claim 8 , wherein the first open end of the retractor is sized to be receivable within the incision in the patient to be arranged proximate to the spine.
12. The system of claim 8 , wherein the first angular position is 180 degrees from the second angular position.
13. The system of claim 8 , wherein the enclosure defines a generally cylindrical body.
14. The system of claim 8 , wherein the trocar has an angle of curvature.
