AI Technical Summary

Technical Problem

Traditional interventional hemostasis methods are time-consuming and complex in patients with multiple injuries, making it difficult to achieve rapid and precise hemostasis at multiple bleeding points. Furthermore, the lack of a real-time feedback mechanism for hemostasis effects may lead to improper dosage of embolization materials or omission of important bleeding points.

Method used

Using remotely controlled magnetic navigation technology, the system acquires angiography image data for three-dimensional reconstruction, generates a magnetic navigation path planning scheme, uses an external magnetic field to drive a magnetic catheter to the bleeding site, and monitors hemodynamic parameters in real time to adjust the path and the amount of embolic material released. Combined with magnetically responsive microspheres, it achieves precise hemostasis.

Benefits of technology

It enables rapid, precise, and coordinated hemostasis at multiple bleeding sites in patients with multiple injuries, reducing operation time and misuse of embolization materials, improving hemostasis success rate and treatment efficiency, and reducing reliance on interventional physicians.

Abstract

The invention relates to the technical field of interventional medical treatment, in particular to a remotely-controlled magnetic navigation multi-injury bleeding interventional synergistic hemostasis method. According to the method, a plurality of bleeding parts are recognized based on angiography images, a magnetic navigation path planning scheme is generated, an in-vitro magnetic field drives an interventional catheter to reach the bleeding parts in sequence, and magnetic responsive microspheres are released for embolism. Haemodynamic parameters are monitored in real time to evaluate the hemostatic effect, and the subsequent path and the release amount of the embolism material are dynamically adjusted. According to the method, accurate and sequential cooperative hemostasis of the multi-injury bleeding part is achieved, and the efficiency and safety of an interventional operation are improved.
