Summary
This study developed a novel navigation system for minimally invasive esophagectomy, improving surgical instrument visualization. The system enhances tumor and lymph node localization, potentially improving patient outcomes.
Area of Science:
- Medical technology
- Surgical navigation systems
- Minimally invasive surgery
Background:
- Minimally invasive esophagectomy faces challenges in precisely locating tumors and lymph nodes.
- Accurate visualization of surgical instruments is crucial for effective tumor resection and lymph node dissection.
Purpose of the Study:
- To develop and evaluate a navigation system for real-time visualization of surgical instruments.
- The system aims to display instrument position relative to tumors and anatomical structures during surgery.
Main Methods:
- An immobilization device was used to minimize patient movement and organ deformation.
- An optical tracking system monitored markers on the surgical instrument and stretcher.
- Preoperative CT data was registered with real-time tracking for instrument visualization.
Main Results:
- The navigation system demonstrated a precision of 0.95 +/- 0.78 mm in accuracy assessments.
- Successful navigation of the instrument to target tumor and structures was achieved in test datasets.
Conclusions:
- The developed navigation system provides real-time instrument positioning relative to tumors.
- This technology may enhance minimally invasive esophagectomy by improving dissection margins and lymph node identification.
