New scalpel with built-in sensors could revolutionize surgery training
A team of researchers from Edinburgh University has developed a scalpel that can measure the amount of force applied by surgeons during procedures. The scalpel could be used to assess and improve the skills of trainees and pave the way for robotic surgery. How the scalpel works The scalpel has a force-sensing system that consists of two thin layers of metal separated by a thin layer of air. When the scalpel is pressed against a surface, the air layer is compressed and changes the electrical resistance of the system. The scalpel can then detect the amount of force applied by…
