A team of engineers is using magnetic force to design new and improved instruments for minimally invasive surgery. The use of magnetic actuation allows them to create tools that are more flexible and ...
The magnetic force between the inner and outer units weakens rapidly as the distance between them increases and, at about an inch, it becomes too weak to keep the inner unit firmly anchored. As a ...
Pietro Valdastri is convinced that the clever application of magnetic force can make minimally invasive surgery easier and more effective. "In 2007, a team of University of Texas researchers did some ...
