0.03 mm Needle guided by Robot used for Retinal Vein Occlusi
Retinal vein occlusion is currently treated with monthly eye injections. Since the retinal vein itself is only around 0.1 millimeter wide. It's just much too thin for manual injections when the drug has to be administered for 10 minutes straight. In a world 1st, researchers have created a robot that can help a surgeon insert the needle precisely and then hold it perfectly still. They also designed the 0.03 millimeter needle, which is three times thinner than human hair, needed to inject the drug into the tiny vein. According to the university, the method successfully dissolved the blood clot and the patient is now doing well.
