Overcoming the Force Limitations of Magnetic Robotic Surgery: Magnetic Pulse Actuated Collisions for Tissue‐Penetrating‐Needle for Tetherless Interventions

摘要

Medical Robotics Robot miniaturization and magnetic forces scale inversely. Providing strong magnetic forces at small scales is a critical challenge for miniature magnetic robots in minimally invasive applications. The presented MPACT-Needle generates 22.7-fold higher forces without increasing the size of the untethered magnetic needle. This allows magnetic needles to penetrate deep in tissues for suturing, drug delivery, and biopsy. More information can be found in article number 2200072 by Onder Erin, Axel Krieger, and co-workers.
