AI Technical Summary
When existing catheters navigate to the target in the patient's body, their positioning changes constantly due to physiological forces such as respiration and heartbeat, making it difficult to accurately maintain the orientation of the distal tip of the catheter relative to the target, thus affecting the treatment effect.
Using an inertial measurement unit (IMU) and a drive mechanism, the orientation of the distal tip of the catheter is determined by receiving data on catheter movement caused by physiological forces. An articulation system is used to maintain the alignment of the distal tip of the catheter with the target, and the catheter position is corrected in real time by combining fluorescence fluoroscopy or ultrasound images.
This achieves stable alignment of the distal catheter tip with the target under varying physiological forces, improving navigation accuracy and treatment effectiveness.
