导管位置、取向和移动方向的检测
By placing a triangular patch on the patient's body surface to receive electromagnetic signals emitted by the catheter electrode, and using a processor to determine the relative orientation of the catheter, the complexity of navigation and the time-consuming calibration during catheter insertion are solved, achieving precise positioning and orientation and reducing damage to patient tissues.

AI Technical Summary
Existing catheterization techniques for diagnosing and treating medical conditions such as arrhythmias present challenges such as complex intra-body navigation of catheters and insertion components, radiation exposure, a large number of components, and time-consuming calibration, which can lead to damage to target organs and tissues.
The catheter, which includes first and second electrodes, is combined with a triangularly configured patch to receive electromagnetic signals on the patient's body surface. The relative orientation of the catheter is determined by a processor, reducing dependence on absolute orientation, simplifying the calibration process, and utilizing the characteristics of electromagnetic signals to distinguish the position and orientation of the catheter.
It enables precise positioning and orientation of the catheter within the patient's body, reduces damage to patient tissues, simplifies the navigation process, and reduces radiation exposure and calibration time.
