Summary
A novel inchworm-like endoscopic robot offers a less invasive and more effective inspection tool. This wireless-powered device provides accurate localization and continuous imaging, improving patient comfort and diagnostic capabilities.
Area of Science:
- Medical Robotics
- Minimally Invasive Surgery
- Biomedical Engineering
Background:
- Conventional endoscopes are limited by large size, causing patient discomfort.
- Incomplete inspection due to limited power and maneuverability is a common issue.
Purpose of the Study:
- To design and evaluate an active, inchworm-like endoscopic robot.
- To overcome limitations of conventional endoscopic devices.
Main Methods:
- The robot utilizes electromagnetic localization and magnetic field vector synthesis.
- Wireless power transmission and real-time image transmission were implemented.
Main Results:
- High wireless power transmission efficiency (>0.9%) was achieved.
- Accurate localization (<10 mm position error, 2° orientation error) was demonstrated.
- Continuous imaging (30 fps) with minimal temperature rise (<1°C) in porcine colon models.
- Simulated electromagnetic exposure remained below international safety standards.
Conclusions:
- The developed endoscopic robot shows significant promise for clinical applications.
- Further research and development are recommended to optimize performance and clinical utility.
