Engineers at Vanderbilt University Create a Magnetically Controlled Robotic Instrument

A team of engineers from Vanderbilt University have developed a new surgical tool that goes beyond the standard endoscopic techniques to allow for truly internal surgery. The new tool is a surgical retractor whose small size allows it to be injected directly into the abdominal cavity and controlled remotely using a joystick. A handheld joystick powers the retractor through the use of a magnet which allows it to steer, and a cylindrical magnet mechanized by a motor that can turn a screw, and the screw drives a mechanism which can pull . After the device’s insertion into the body, the joystick is placed on the stomach above the retractor, allowing a surgeon to control the device. The device is still in developmental stages, but the video above features the lead engineers explaining the logistics of the device and demonstrating its use.
