Abstract
A digitizer pointer is provided as part of a system for correcting a curvature or deformity in a patient's spine based on the digitized locations of implanted screws and tracking the placement of the rod as it is placed in a minimally invasive fashion. The digitizer pointer includes an offset adjustment feature, a swivel feature, and a translation feature.
Claims20
A method comprising:
- making a digitizer pointer available for use;
- coupling a tracking array to the digitizer pointer;
- adjusting an offset feature of the digitizer pointer;
- adjusting a swivel feature the digitizer pointer;
- adjusting a translating feature of the digitize pointer;
- and
- digitizing, with the digitizer pointer, a location of a screw implanted in a patient.
4 more elements
A method comprising:
- making available for use a digitizing pointer that includes:
- a first component having a proximal end with a first attacher and a distal end defining a recess;
- and
- a second component linearly aligned with the first component and having:
- a proximal elongated shaft segment having a proximal end comprising a cavity formed within the proximal end and a retainer engaging the recess;
- a distal elongated shaft segment having a second attacher;
- and
- a guide pin extending laterally away from the second component;
- rotating the first component relative to the second component;
- coupling a tracking array to the first attacher;
- and
- digitizing, with the digitizer pointer, a location of a screw implanted in a patient using the second attacher.
9 more elements
A method comprising:
- making a digitizer pointer available for use;
- and
- transitioning the digitizer pointer from a first mode in which a fork of the digitizer pointer is disposable in a pedicle screw tulip to a second mode in which a lobe extends past a distal end of the fork.
