Summary
A new ultrasound-guided navigation system accurately tracks tissue shift during minimally invasive neck surgery, enhancing surgeon orientation and safety. This system achieves a 2 mm registration error for improved endoscopic procedures.
Area of Science:
- Medical Engineering
- Surgical Navigation
- Medical Imaging
Background:
- Minimally invasive neck surgery demands precise intra-operative navigation.
- Tissue shift due to patient positioning complicates surgical orientation.
- Real-time visualization of anatomical landmarks and instruments is crucial.
Purpose of the Study:
- To develop an ultrasound-supported navigation system for endoscopic neck surgery.
- To account for intra-operative tissue shift in surgical guidance.
- To improve surgeon accuracy and safety in neck procedures.
Main Methods:
- Utilized preoperative imaging integrated with an ultrasound-supported system.
- Developed a rotatable, flexible neck model to analyze tissue shift.
- Evaluated system performance in detecting tissue displacement and aiding navigation.
Main Results:
- The developed navigation system successfully detected intra-operative tissue shift.
- A total registration error of 2 mm was achieved.
- The system provides essential visualization of landmarks and instruments.
Conclusions:
- The ultrasound-supported navigation system enhances safety in minimally invasive neck surgery.
- Accurate tracking of tissue shift is vital for endoscopic procedures.
- This technology offers improved orientation for surgeons during complex neck operations.
