Method and apparatus for spinal fixation
First Claim
1. A device used for deploying a spinal fixation device comprising:
- an elongated cannulated member having a proximal end, a distal end, a first longitudinal axis extending therebetween, and an outer surface, the cannulated member comprising an elongated opening on the outer surface; and
a handle extending along a second longitudinal axis;
wherein the first and second longitudinal axis form an angle with respect to each other; and
wherein the elongated cannulated member is configured to receive longitudinally through it an elongate tubular member having a third longitudinal axis;
wherein the elongated opening is configured to receive the elongate tubular member when the third longitudinal axis is transverse to the first longitudinal axis.

Abstract
Fusion of cervical spinal vertebrae with one or more fixation devices can be accomplished with the described tools and methods. For example, a guidewire introducer can include a tubular introducer cannula and a handle. The handle can be angularly offset from the introducer cannula such that positioning of the introducer on the cervical spine does not interfere with a patient'"'"'s head. A sheath assembly can include inner and outer sheath bodies and a handle. The handle is angularly offset from the sheath bodies such that the sheath assembly can be applied to the cervical spine without interference to the patient'"'"'s head. The sheath body can be curved or straight. Various tools such as drills, tapping devices, compression tools, and pin release tools can be applied to the cervical spine through the sheath body to apply the fixation device. The tools can include elongate flexible shafts.

8. A wire introducer for creating a tissue track for a guidewire, the wire introducer comprising:
-
an elongated cannulated member having a first longitudinal axis, a distal end and a proximal end, the distal end including at least one cutting element; a handle extending along a second longitudinal axis, wherein the first and second longitudinal axes form an angle with respect to each other; a trocar having a distal end with a sharpened tip and a proximal end with a cavity, the trocar positioned within the cannulated member such that the distal end extends beyond the elongated cannulated member; and a strike pin having a distal end configured to couple with the cavity of the trocar and a proximal end configured to receive a longitudinal impact force. - View Dependent Claims (9, 10, 11, 12)
