Experts build robot to remove stomach cancer

Scientists develop crab-like device after seafood dinner in Singapore

SINGAPORE - Inspired by Singapore's famous chilli crab dish, researchers have created a miniature robot with a pincer and a hook that can remove early-stage stomach cancers without leaving any scars.

Mounted on an endoscope, it enters the patient's gut through the mouth. It has a pincer to hold cancerous tissues, and a hook that slices them off and coagulates blood to stop bleeding.
