Summary
This study introduces augmented reality surgical navigation systems that overlay 3D patient models onto surgical screens. These systems enhance surgeon visualization of critical anatomy, improving safety in procedures like endoscopic sinus and hepatobiliary-pancreatic surgery.
Area of Science:
- Medical Technology
- Surgical Innovation
- Computer-Aided Surgery
Background:
- Surgical procedures require precise visualization of internal anatomy.
- Traditional methods can limit a surgeon's view of critical structures.
- The integration of advanced imaging and display technologies is crucial for improving surgical outcomes.
Purpose of the Study:
- To develop and evaluate augmented reality (AR) based surgical navigation systems.
- To enhance surgical safety by providing real-time visualization of patient-specific anatomy.
- To improve surgeons' intuitive understanding of the surgical field.
Main Methods:
- Utilizing augmented reality technology to superimpose 3D patient organ models.
- Reconstructing 3D models from pre-operative X-ray CT data.
- Developing navigation systems with adaptable peripheral equipment and display methods for different surgical fields.
Main Results:
- AR systems successfully display hidden anatomical risk materials, tumors, and blood vessels.
- Surgeons gain an intuitive grasp of the operational field's inner structures.
- Navigation systems tailored for endoscopic sinus surgery and hepatobiliary-pancreatic surgery were developed.
Conclusions:
- Augmented reality surgical navigation systems significantly enhance surgical safety.
- These systems improve intraoperative visualization and spatial understanding.
- The developed navigation systems are adaptable to various surgical specialities.
