Abstract
A method of preparing an intervertebral disc space between a pair of vertebral bodies to receive an implant comprises engaging a portion of a surgical instrument with at least one of the vertebral bodies. The surgical instrument has a passage therethrough. The method further comprises generating one or more images of the surgical instrument in the surgical field and visualizing the passage through the surgical instrument on the one or more images. The method further comprises aligning the surgical instrument with a surgical plane through the intervertebral disc space by maintaining visualization of the through passage on the one or more images while adjusting the surgical instrument.
Claims23
A method of preparing an intervertebral disc space between a pair of vertebral bodies to receive an implant, the method comprising:
- engaging a portion of a surgical instrument with at least one of the vertebral bodies, the surgical instrument having a passage therethrough;
- generating one or more images of the surgical instrument in the surgical field;
- on the one or more images, visualizing the passage through the surgical instrument;
- and
- aligning the surgical instrument with a surgical plane through the intervertebral disc space by maintaining visualization of the through passage on the one or more images while adjusting the surgical instrument.
A surgical instrument comprising:
- an instrument body at least a portion of which is adapted for interposition between a pair of vertebral bodies and
- a first through opening in the instrument body, the first through opening defining a first axis through the instrument body,
- wherein the first through opening is adapted for visualization with an imaging device when the first axis is generally perpendicular to a first image plane generated by the imaging device.
A method for assessing an orientation of a surgical instrument in a surgical field comprising:
- positioning at least a portion of the surgical instrument in the surgical field, the surgical instrument having first and second passages therethrough;
- generating a first image of the surgical instrument;
- on the first image, visualizing an axis of sight through the first passage in the surgical instrument;
- generating a second image of the surgical instrument;
- and
- on the second image, visualizing an axis of sight through the second passage in the surgical instrument.
