Tiny 'wrist' to assist needle surgery

Quote: A tiny flexible wrist component for needle-sized surgical equipment could enable surgeons to perform operations in tiny spaces which would involve incisions so small that they could be sealed just with surgical tape, rather than sutures. Less than 2mm in diameter, the wrist, which would form part of the suite of equipment for a type of minimally invasive technique known as needlescopic surgery, has ben developed by engineers at Vanderbilt University in Nashvile, Tennessee.
