Summary
This study demonstrates that a vascular interventional robotic system is safe and reliable for angiography in preliminary experiments. While effective for certain procedures, further improvements are needed for enhanced flexibility.
Area of Science:
- Medical Robotics
- Vascular Interventions
- Surgical Technology
Background:
- Robotic systems are increasingly used in surgery, but their application in vascular interventional therapy lags.
- Development of specialized robotic systems for vascular procedures is crucial.
Purpose of the Study:
- To assess the reliability and safety of a novel vascular interventional robotic system.
- To validate the system's performance through in vitro and animal experiments for angiography.
Main Methods:
- A proprietary vascular interventional robot system was utilized for experiments.
- The system includes a remote steering console, propulsion/rotation system, and hydraulic fixation.
- Surgeons remotely controlled the system via a 3D interface in glass vessel models and animal subjects.
Main Results:
- The robotic system successfully navigated vessel models with internal diameters >3mm and angles <90°.
- Angiography of the renal artery, vertebral artery, and common carotid artery was smoothly performed in adult dogs.
- No surgical complications were reported during animal experiments.
Conclusions:
- Vascular interventional robotic system angiography is demonstrated as safe and reliable.
- The system allows for remote completion of angiograms, meeting basic expectations.
- Future improvements are necessary to enhance system flexibility, particularly regarding wire control and force feedback.
