Laser Tracking of Surgical Instruments and Implants
First Claim
1. A projection system comprising:
- a tracking system comprising;
a first source of light and a first light sensor;
a second source of light and a second light sensor, anda reflector,wherein the first light sensor records a first direction the first source is pointed when it receives a reflection of the first light source from the reflector,wherein the second light sensor records a second direction the second source is pointed when it receives the reflection of the second light source from the reflector;
a processing system configured to determine a point in space corresponding to an intersection of the first and second directions, and to calculate the relationship between the first and second light sources and the reflector.

Abstract
A projection system includes a tracking system comprising a first source of light and a first light sensor; a second source of light and a second light sensor, a reflector, and a processing system. The first light sensor may record a first direction the first source is pointed when it receives a reflection of the first light source from the reflector. The second light sensor may record a second direction the second source is pointed when it receives the reflection of the second light source from the reflector. The processing system may determine a point in space corresponding to an intersection of the first and second directions, and may calculate the relationship between the first and second light sources and the reflector.

8. A laser projection system comprising a tracking system, the tracking system comprising:
-
one or more reflectors; a first laser source having multiple degrees of freedom such that any point in space within a field of view can be targeted at a rapid rate; a first receiving device that is triggered when illuminated by light from the first laser source that has reflected back from the one or more reflectors; a second laser source having multiple degrees of freedom such that any point in space within the field of view can be targeted at a rapid rate; and a second receiving device that is triggered when illuminated by light from the second laser source that has reflected back from the one or more reflectors; and a processing system configured to determine the position of the one or more reflectors relative to the first and second laser sources. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A method of determining positional information for use during surgery comprising:
-
providing a tool with at least one reflector and a laser projector system with at least a first laser proctor and a second laser projector, each being associated with a respective first light sensor and a second light sensor; scanning a workspace with a first laser beam of the first laser projector; capturing a first reflection of the first laser beam from the at least one reflector with the first light sensor located near the first laser projector; recording the orientation of the first laser beam when the first reflection is captured; scanning the workspace with a second laser beam of the second laser projector; capturing a second reflection of the second laser beam from the at least one reflector with the second light sensor located near the second laser projector; recording the orientation of the second laser beam when the second reflection is captured; and calculating the position of the at least one reflector relative to the laser projector system based upon the orientation of the first and second laser beams. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)
