160801092956_1_540x360A small vibrating device added to surgical tools could improve surgeons’ sensitivity to different shapes and textures inside their patients’ bodies. Engineers have designed the small vibrating device to attach to any existing hand-held surgical tool and be used instantly, without requiring extra training for doctors.
