Method and apparatus for implantation between two vertebral bodies
First Claim
Patent Images
1. An apparatus to determine a position for implanting a prosthesis in an anatomy, comprising:
- an instrument including a sensor;
a system operable to navigate a procedure, including a tracking system that tracks the sensor to determine a position of the instrument relative to the anatomy, the tracking system spaced apart from the instrument;
an imaging device to obtain image data of the anatomy;
a display that displays the image data;
a user input device that enables a user to select a plurality of points on the image data displayed on the display;
wherein said system is configured to determine a first anatomical definition based substantially only on the plurality of points, the first anatomical definition including at least a midline plane of a spinal column;
wherein said first anatomical definition is substantially independent of the orientation of the image data; and
wherein an icon that represents the prosthesis is displayed on the display relative to the image data, and the icon changes when the prosthesis is on the midline plane.

Abstract
A method and system to assist in a planning and navigation of procedure. Generally, the system allows for image acquisition of a selected area of the anatomy. The images may then be used to mark various points to determine true anatomical definitions and planes. The definitions may assist in positioning a prosthesis.

18. A method of selecting a position for a prosthesis to be implanted in an anatomy, comprising:
-
obtaining image data of the anatomy that includes at least two substantially adjacent vertebrae; displaying the image data viewable by a user; defining a plurality of points on the displayed image data that includes a posterior point on a spinous process, a lateral point on a transverse process of a vertebra, a lateral point on a vertebral body of a vertebra, or combinations thereof; determining an anatomical definition in part due to the defining of the plurality of points; defining a second plurality of points on the displayed image data relative to at least one of the adjacent vertebrae; determining a depth plane for the insertion of the prosthesis based on the second plurality of points; tracking a sensor coupled to an instrument; determining a position of the instrument relative to at least one of the anatomical definition and the depth plane during the procedure based on tracking of the sensor; and navigating a surgical procedure relative to the determined anatomical definitions. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43)

44. A surgical system operable to allow for defining an anatomical definition and navigating a procedure relative to an anatomy, comprising:
-
a prosthesis including a sensor, the prosthesis selected from the group consisting of a nucleous replacement, a disc replacement, a disc fusion apparatus, and combinations thereof; a tracking array to track a position of the sensor; an imaging device operable to obtain image data of the anatomy; a display to display the image data and a position of the prosthesis relative to the anatomy during the procedure; a user input device that allows a user to input a first anatomical definition and at least one depth point for the prosthesis based on the image data; a processor that determines a second anatomical definition based on the first anatomical definition and determines an insertion depth for the prosthesis within the anatomy based on the least one depth point; wherein said first anatomical definition, said second anatomical definition and said insertion depth assist in navigating the procedure; and wherein said display displays an indicator that illustrates whether the prosthesis has reached said insertion depth. - View Dependent Claims (45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63)
