Core Viewpoint - The article discusses the advancements in MRI-guided robotic systems for neurointervention, highlighting the urgent clinical need for precise treatment of neurological diseases and the innovative technologies developed to address existing challenges in this field [1][4][5]. Group 1: Current Challenges in Neurointervention - Neurological diseases have become the second leading cause of death globally, with a significant increase in prevalence among aging populations [1]. - Traditional stereotactic surgery methods are complex and heavily reliant on the surgeon's experience, while existing robotic systems lack real-time imaging capabilities, making them less effective in dynamic surgical environments [3]. Group 2: Technological Innovations - The "Intelligent Robot" project aims to develop a brain intervention MRI-compatible puncture robot, focusing on key areas such as drive systems, perception, imaging navigation, and implantable devices [3][4]. - The project has successfully created the world's first MRI-guided robotic system for neurointervention, featuring high precision and advanced imaging capabilities [5]. Group 3: System Components and Performance - The MRI-guided robotic system consists of an 8-degree-of-freedom pneumatic-hydraulic actuation system and a 2-degree-of-freedom soft robotic driver, enabling precise navigation and control during surgery [7][11]. - The 8-degree-of-freedom system provides extensive coverage of the brain, with a positioning accuracy of less than 1 mm and excellent MRI compatibility [8]. Group 4: Clinical Validation and Results - The robotic system has undergone extensive testing, including experiments on human specimens and live animals, demonstrating high accuracy and clinical applicability [19][22]. - In human specimen tests, the system achieved a final positioning accuracy of 0.68±0.13 mm, effectively adapting to anatomical changes during surgery [23]. Group 5: Future Implications - The advancements in MRI-guided robotic systems are expected to enhance the precision and safety of neurointerventions, contributing to the development of minimally invasive treatment options for neurological diseases [5][24].
