Systems and methods for assisted surgical navigation
In at least one embodiment, a method of surgical navigation is provided. The method includes receiving an external three-dimensional model of a surgical site from the viewpoint of a headset, wherein the external three-dimensional model is derived from reflected light. The method further includes aligning the external three-dimensional model with an internal three-dimensional model of the surgical site from the viewpoint of the headset, wherein the internal three-dimensional model is derived from medical imaging, and generating an aligned view. The method further includes providing the aligned view to the headset, and updating the aligned view in real-time while the headset is moved or the surgical site is moved or modified during a surgical procedure.
1. A system to product a three-dimensional model of a surgical site, comprising:
a projector mounted to a user's headset to project an array of non-visible light beams onto a surgical site;
a camera mounted to the headset to collect light reflected from the surgical site back towards the headset to produce optical data regarding the surgical site;
a laser pointer to light up reference landmarks on anatomical reference features; and
a processor mounted to the headset, the processor configured to:
construct a non-video-based external three-dimensional model based on the optical data,
produce mapping points by associating annotations provided as the laser pointer lights up respective reference landmarks, and receive user instructions to highlight and inspect respective ones of the anatomical reference features based on the reference landmarks,
wherein the three-dimensional model of the highlighted anatomical reference features is rotatable and divisible according to user instructions to inspect the anatomical reference features.
2. The system of claim 1 , wherein the user instructions to inspect the anatomical reference features include an instruction to raise the three-dimensional model of the highlighted anatomical reference features from an aligned view to an unaligned view.
3. The system of claim 2 , wherein the user instructions to inspect the anatomical reference features include an instruction to rotate the three-dimensional model of the highlighted anatomical reference features.
4. The system of claim 2 , wherein the user instructions to inspect the anatomical reference features include an instruction to divide the three-dimensional model of the highlighted anatomical reference features.
5. The system of claim 2 , wherein the user instructions to inspect the anatomical reference features include an instruction to scroll through slices of the virtual model.
6. The system of claim 2 , wherein the user instructions to inspect the anatomical reference features include an instruction to enlarge the size of the three-dimensional model of the highlighted anatomical reference features.
7. The system of claim 6 , wherein the user instructions to inspect the anatomical reference features include an instruction to divide the three-dimensional model of the highlighted anatomical reference features are provided by thumb and forefinger gestures made by the user.
8. The system of claim 2 , wherein the user instructions to inspect the anatomical reference features are provided using surgical gloves having RFID chips inserter therein.
9. The system of claim 1 , wherein the highlighted anatomical reference features include implants, and wherein further the three-dimensional model of the highlighted anatomical reference features are embedded in a memory.
10. The system of claim 9 , wherein the processor is configured to determine a fit of an implant by accessing a virtual library of surgical implants upon receipt of the user instructions to highlight an inspect respective ones of the anatomical reference features.
11. The system of claim 1 , wherein the highlighted anatomical reference features include implants, and
wherein the processor is further configured to:
store highlighted anatomical reference features that are embedded in a memory in virtual chronology, and define a fit of an implant.
