Core Viewpoint - A research team from the Shenzhen Institute of Advanced Technology and Zhejiang University has developed a flexible magnetic positioning patch system that offers high-precision, real-time tracking for medical instruments during minimally invasive surgeries, potentially enhancing surgical safety and efficiency [1][3]. Group 1: Technology Development - The research team created a customizable, attachable flexible magnetic positioning patch based on flexible printed circuit boards, which can be designed in various shapes and sizes to suit specific needs [3]. - This patch can be applied directly to the skin or integrated into medical instruments like endoscopes, providing immediate usability akin to a "flexible GPS" for precise guidance during medical procedures [3]. Group 2: Methodology and Validation - The team developed a dual-stage positioning algorithm that functions similarly to satellite navigation systems, first determining the patch's position in a global coordinate system using an external magnetic field, and then using the patch as a local reference for locating small magnetic targets within the body [3][5]. - Systematic validation of this method showed high-precision positioning capabilities in simulated experiments for brain artery interventions and ERCP guidewire placements, demonstrating its effectiveness in specific medical applications [5]. Group 3: Application Potential - The magnetic positioning strategy has shown good stability and versatility in various clinical scenarios, including surgical navigation and external physiological monitoring, indicating its broad application potential in the medical field [5].
