This new technology offers a potentially less invasive alternative to the traditional surgical methods currently used to clear tubal obstructions, which often involve the use of conventional catheters and guidewires.
The microrobot is made from nonmagnetic photosensitive resin, coated with a thin iron layer to give it magnetic properties. By applying an external magnetic field, the robot rotates, generating translational motion.
The design of the microrobot is another key innovation. It has a screw-shaped body with a helical structure, a cylindrical central tube, and a disk-shaped tail.
In tests, the microrobot demonstrated both effectiveness and efficiency in clearing the simulated blockage, with the vortex created by the rotating screw propelling debris away from the obstruction.
