Intelligent Robotic Catheter System for Precise Interventional Treatment of Atrial Fibrillation

Atrial fibrillation is one of the most common persistent arrhythmia diseases worldwide, and radiofrequency catheter ablation has become the first-line minimally invasive treatment clinically. However, traditional manual catheter operation relies heavily on the surgeon’s clinical experience, resulting in inconsistent operation accuracy, prolonged intraoperative fluoroscopy time, and increased radiation exposure for both patients and medical staff. In recent years, robotic interventional medical devices have achieved rapid iterative updates in cardiovascular intervention fields. This study develops a novel intelligent robotic catheter system integrated with real-time 3D cardiac mapping and force-sensing feedback technology. The device is equipped with a micro high-precision pressure sensor at the catheter tip, which can continuously monitor the contact force between the catheter and cardiac tissue within the safe threshold range, effectively avoiding myocardial perforation and excessive ablation damage caused by improper force control. Combined with artificial intelligence image recognition algorithms, the system can automatically construct a three-dimensional model of the left atrium, accurately locate abnormal electrical conduction lesions, and complete standardized radiofrequency ablation with autonomous path planning. Clinical trial data shows that compared with traditional manual surgery, the robotic catheter system reduces the operation time by 35% and cuts down fluoroscopy exposure time by more than 60%, while significantly improving the one-time success rate of ablation surgery. This intelligent robotic interventional device solves the core pain points of low precision and high radiation risk in traditional atrial fibrillation ablation, and provides a standardized, safe and efficient new equipment solution for cardiovascular minimally invasive intervention.
