Summary
This study introduces an autonomous catheter insertion system using magnetic motion capture to reduce fluoroscope use in endovascular surgery. The system achieved accurate catheter control and path reproduction in simulated vasculature.
Area of Science:
- Medical Robotics
- Surgical Navigation
- Biomedical Engineering
Background:
- Reducing fluoroscope usage is critical in endovascular surgery to minimize radiation exposure.
- There is a growing need for autonomous systems to enhance precision and efficiency in minimally invasive procedures.
Purpose of the Study:
- To develop and evaluate an autonomous catheter insertion system for endovascular surgery.
- To utilize magnetic motion capture for real-time catheter tracking and feedback control.
Main Methods:
- A system was developed employing a magnetic motion capture sensor to track catheter position and speed.
- The system provided feedback to a catheter-driving mechanism for autonomous insertion in a silicone vasculature model.
- Experiments focused on catheter insertion speed control and path reconstruction accuracy.
Main Results:
- The autonomous system successfully controlled catheter insertion at speeds of 6.14 mm/s.
- Two-dimensional path reconstruction within the silicone blood vessel phantom demonstrated an error of less than 7 mm.
Conclusions:
- Catheter insertion speed control accuracy is influenced by friction between the catheter and the vessel model.
- Path reconstruction error is a function of the model's diameter, insertion mechanism, magnetic sensor, and guidance technique.
