This study developed a mixed reality (MR) digital surgery system for maxillofacial procedures. The system enhances surgical navigation by overlaying 3D information, improving efficiency and reducing reliance on spatial imagination.
Area of Science:
- Medical Technology
- Surgical Navigation
- Mixed Reality Applications
Background:
- Traditional surgical navigation systems present challenges in visual and spatial conversion for surgeons.
- Integrating advanced display technologies can potentially overcome these limitations.
Purpose of the Study:
- To develop a three-dimensional visual output for surgical navigation information.
- To achieve seamless integration between mixed reality (MR) display devices and high-precision optical navigators.
Main Methods:
- Utilized quaternion-based point alignment algorithms for precise positioning and calibration of MR devices and optical navigators.
- Developed a visual positioning and tracking system for MR-assisted surgery using open-source SDKs.
- Conducted a pilot study involving four patients undergoing MR-assisted tumor resection and reconstruction, followed by postoperative CT analysis for error assessment.
Main Results:
- Successfully integrated MR display equipment with a high-precision optical navigator.
- Developed and implemented a digital maxillofacial surgery system leveraging MR technology.
- Demonstrated successful application of MR-assisted tumor resection and reconstruction in four clinical cases.
Conclusions:
- The MR-based digital maxillofacial surgery system effectively superimposes 3D navigation data into the surgeon's field of view.
- This system improves surgical efficiency, reduces the need for spatial reasoning, and aids in protecting critical anatomical structures.
- The technology holds significant clinical value and potential for advancing digitally assisted surgery.
