Microsure MUSA Robot Used for First Time on Real Patients
In a world first, clinicians at Maastricht University have used a robot to perform "supermicrosurgeries", which involved operating on vessels as small as 0.3 mm in diameter. The procedures were conducted on women with lymphedema, a condition...
