A scope that uses ultrasound to examine and treat the gall bladder - the first of its kind in the nation - was recently invented at No 2 Hospital of Panyu district, Guangzhou.

The patented device can find tiny gallstones often missed by surface ultrasound, said its inventor Qiao Tie, director of the hospital.

The new device penetrates the gall bladder and provides a clearer view, he said.
