Abstract

A surgical guide assembly having an attachment device configured to be coupled to a bone. A cut location indicator is coupled to the attachment device. The cut location indicator identifies a location where the bone is to be cut. An arm is coupled to the attachment device, the cut location indicator, or both. A support structure is coupled to the arm. The support structure is configured to have a trackable feature coupled thereto.

First claim

What is claimed is:

1. A surgical guide assembly for craniomaxillofacial procedures, comprising:
an implant surgical guide assembly, comprising
at least one attachment device configured to be coupled to a craniomaxillofacial implant;
a trackable feature coupled to the at least one attachment device of the implant surgical guide assembly; and
a tracker dynamically tracking the trackable feature of the implant surgical guide assembly in three-dimensional space to provide intraoperative positioning feedback; and,
a recipient surgical guide assembly, comprising at least one attachment device configured to be coupled to a craniomaxillofacial bone of a recipient;
a trackable feature coupled to the at least one attachment device of the recipient surgical guide assembly; and
a tracker dynamically tracking the trackable feature of the recipient surgical guide assembly and the trackable feature of the implant surgical guide assembly to provide intraoperative positioning feedback,
wherein the surgical guide assembly includes two or more networked workstations with integrated planning and navigation modules, which networked workstations are concurrently used in planning and navigation of two simultaneous surgeries for both donor and recipient irrespective of geographic proximity.

2. The surgical guide assembly of claim 1 , wherein the implant surgical guide assembly includes a cut location indicator.

3. The surgical guide assembly of claim 2 , wherein the cut location indicator is a custom cutting guide manufactured via additive manufacturing techniques.

4. The surgical guide assembly of claim 1 , wherein the recipient surgical guide assembly includes a computer work-station and the implant surgical guide assembly includes a computer work-station.

5. The surgical guide assembly of claim 4 , further including a communication link between the recipient surgical guide assembly and the implant surgical guide assembly.

6. The surgical guide assembly of claim 5 , wherein the recipient surgical guide assembly and the implant surgical guide assembly provide real-time feedback.

7. The surgical guide assembly of claim 1 , further including a communication link between the recipient surgical guide assembly and the implant surgical guide assembly.

8. The surgical guide assembly of claim 1 , wherein the recipient surgical guide assembly and the implant surgical guide assembly provide real-time feedback.

9. The surgical guide assembly of claim 1 , wherein the trackable feature of the implant surgical guide assembly is a reflective sphere.

10. The surgical guide assembly of claim 9 , wherein the trackable feature of the recipient surgical guide assembly is a reflective sphere.

11. The surgical guide assembly of claim 1 , wherein the craniomaxillofacial implant is a donor implant, a dental implant, or a craniofacial prosthetic.

12. The surgical guide assembly of claim 1 , wherein the craniomaxillofacial implant is a bone of a donor.

13. The surgical guide assembly of claim 1 , wherein the craniomaxillofacial implant is a custom craniofacial implant.
