Innovative assistive device to improve suture control in confined surgical fields: A preliminary report towards clinical trial

Objectives Precise suture control in confined surgical fields remains technically challenging, often leading to increased operative time and surgeon fatigue. To address this limitation, we developed a novel assistive device, MagnaSuture, designed to provide improved needle capture and directional guidance in restricted operative spaces. Material and Methods Using AutoCAD (Autodesk Inc., USA), a prototype was modeled with components enabling directional guidance and controlled needle capture. The device was fabricated using a biocompatible polymer and integrated with a neodymium magnet for atraumatic needle engagement. Bench testing was conducted to evaluate mechanical strength, while ergonomic feasibility was assessed by surgeons using a 5-point Likert scale. Results Bench testing confirmed satisfactory mechanical strength of the prototype. Ergonomic evaluation demonstrated high user satisfaction, particularly in ease of handling and precision of needle capture. The device was reported to improve visibility and reduce the need for repeated instrument adjustments. Conclusion The MagnaSuture prototype demonstrated satisfactory mechanical performance and ergonomic feasibility in preliminary testing. Further mock surgical evaluation and clinical trials are warranted to validate its safety and efficacy in improving surgical outcomes.
