Abstract

A method for computer-assisted planning of a transplant surgery is provided. The method includes obtaining a computer-readable representation of a donor and recipient skeletal fragment; determining surgical cutting planes on the computer-readable representation of the donor skeletal fragment from which a portion of the donor skeletal fragment from the computer-readable representation of the donor skeletal fragment will be harvested; determining virtual cutting guides; performing a virtual osteotomy to separate the portion of the donor skeletal fragment from the computer-readable representation of the donor skeletal fragment from a remainder portion of the donor skeletal fragment based on a position of the virtual cutting guides that are attached to the computer-readable representation of the donor skeletal fragment; positioning the donor skeletal fragment within a transplant region of the recipient skeletal fragment; and creating a hybrid computer-readable representation comprising the recipient skeletal fragment and the portion of the donor skeletal.

First claim

What is claimed is:

1. A computer-implemented method for computer-assisted planning of craniomaxillofacial surgery, the method comprising:
obtaining a computer-readable representation of an implant;
obtaining a computer-readable representation of a recipient skeletal fragment;
positioning the computer-readable representation of the implant within a region of the computer-readable representation of the recipient skeletal fragment;
creating a hybrid computer-readable representation comprising the computer-readable representation of the recipient skeletal fragment and the computer-readable representation of the implant during or after the positioning;
tracking movement of the computer-readable representation of the implant during the positioning;
updating the hybrid computer-readable representation based on the movement being tracked; and
providing the hybrid computer-readable representation as an output.

2. The computer-implemented method of claim 1 , wherein the implant is a craniofacial implant.

3. The computer-implemented method of claim 1 , wherein the craniomaxillofacial surgery is a cranioplasty.

4. The computer-implemented method of claim 1 , wherein the craniomaxillofacial surgery is a single-stage implant cranioplasty.

5. The computer-implemented method of claim 1 , wherein the craniomaxillofacial surgery is a craniomaxillofacial reconstructive surgery.

6. The computer-implemented method of claim 1 , wherein the craniomaxillofacial surgery is an orthognathic surgery.

7. A system for computer-assisted planning of craniomaxillofacial surgery, comprising:
a memory storing instructions; and
at least one processor coupled to the memory and executing the instructions to perform a method of computer-assisted planning of craniomaxillofacial surgery, the method comprising:
creating a computer-readable representation of an implant;
creating a computer-readable representation of a recipient skeletal fragment based on one or more medical imaging techniques, wherein the computer-readable representation of the recipient skeletal fragment and the computer-readable representation of the implant comprises a segmented 3D reconstruction model, and wherein each voxel of the segmented 3D reconstruction model comprises an associated anatomical attribute that classifies an anatomy for which each voxel represents;
positioning the computer-readable representation of the implant within a region of the computer-readable representation of the recipient skeletal fragment;
creating a hybrid computer-readable representation comprising the computer-readable representation of the recipient skeletal fragment and the computer-readable representation of the implant during or after the positioning; and
providing the hybrid computer-readable representation as an output.

8. The system of claim 7 , wherein the implant is a craniofacial implant.

9. The system of claim 7 , wherein the craniomaxillofacial surgery is a cranioplasty.

10. The system of claim 7 , wherein the craniomaxillofacial surgery is a single-stage implant cranioplasty.

11. The system of claim 7 , wherein the craniomaxillofacial surgery is a craniomaxillofacial reconstructive surgery.

12. The system of claim 7 , wherein the craniomaxillofacial surgery is an orthognathic surgery.

13. A system for computer-assisted planning of a craniomaxillofacial surgery, comprising:
a memory storing instructions; and
at least one processor coupled to the memory and executing the instructions to perform a method of computer-assisted planning of craniomaxillofacial surgery, the method comprising:
obtaining a computer-readable representation of an implant;
obtaining a computer-readable representation of a recipient skeletal fragment;
positioning the computer-readable representation of the implant within a region of the computer-readable representation of the recipient skeletal fragment;
creating a hybrid computer-readable representation comprising the computer-readable representation of recipient skeletal fragment and the computer-readable representation of the implant during or after the positioning;
tracking movement of the computer-readable representation of the implant during the positioning; and
updating the hybrid computer-readable representation based on the movement being tracked.

14. The system of claim 13 , wherein the implant is a craniofacial implant.

15. The system of claim 13 , wherein the craniomaxillofacial surgery is a cranioplasty.

16. The system of claim 13 , wherein the craniomaxillofacial surgery is a single-stage implant cranioplasty.

17. The system of claim 13 , wherein the craniomaxillofacial surgery is a craniomaxillofacial reconstructive surgery.

18. The system of claim 13 , wherein the craniomaxillofacial surgery is an orthognathic surgery.

19. The system of claim 13 , further including the step of providing the hybrid computer-readable representation as an output.
