Description
Summary:The progress of medical procedures towards minimally invasive techniques has led to notable advancements in medical device engineering, particularly in the navigation and control of catheters within complex anatomical structures. This study introduces a novel handheld device using the Magnetic Tractor Beam (MTB) that aims to improve the accuracy and safety of catheter navigation during lung interventions. The device aims to overcome the limitations of traditional catheterisation, which include restricted manoeuvrability and the potential for tissue damage, by utilising magnetic fields to manipulate catheters without direct contact. The device focuses on user-centric design and uses iterative feedback to improve its functionality. The device's efficacy in achieving precise control over catheter movement is demonstrated through comprehensive experiments, with a particular focus on navigating the complex pathways of the respiratory system. The experimental setup comprises the fabrication of a trachea and bronchi model using 3D printing, the refinement of magnetic configurations to achieve the highest possible MTB effect, and thorough testing to verify the precision and control mechanisms of the device. The results demonstrate a notable enhancement in the rates of successful navigation and a decrease in the possibility of tissue perforation. The study highlights the significance of real-time imaging and accurate control in improving the effectiveness of catheter-based interventions.
