Micro robot for surgery

The magnetic field will stretch the robot, making it no bigger than a fingerprint. Frequency of 2 kilohertz can cause roboot motion, stretching it small enough to enter the bloodstream. A micro robot can be injected into the body through a syringe that will be used by physicians to analyze health conditions, administer drugs, or perform surgery in very small areas.

This micro-biomedical robot system was developed by a team of scientists at the Swiss Federal Institute of Technology in Zurich. This is the smallest unit in the same category, and has been successfully tested in the laboratory.

This ultra-small robot is specially designed to pass through the blood vessels of the heart or the fluid behind the eyes and in the ear to diagnose and treat the disease, helping the patient to have less pain and recovery time. faster.

"Another application we are actively considering is the use of this device for eye surgery, where the device will be inserted into the eye, to the retina to infuse drugs into the retinal veins of size as human hair, 'said Brad Nelson, professor of robotics and intelligent systems, head of research.

Unlike most conventional mobile robots - those that either use battery power or are connected to an electrical cable to control its activity, the robot's activity is based on the magnetic field emitted by one machine. For example, a 2 kilohertz frequency can move the robot, stretching it small enough to put it into the bloodstream. The frequency of 3 kilohertz can be adjusted by a syringe into a blood vessel.

The invention will be published for the first time at the 8th International Symposium on Computer Image and Computer Aids in Medicine in October.
