Stomach cancer removed without scars

Created in Singapore a robot miniature pliers and hook able to remove early-stage cancers of the stomach without leaving scars. Mounted on an endoscope, the patient enters the intestine through the mouth and has a clamp keep the cancer tissues and a hook that helps to cut and coagulate blood to stop bleeding. With the help of a small camera attached to the endoscope, the surgeon can see what is there ‘in the body and controls the robotic arms at a distance, sitting in front of a monitor. "The robots are made capable of performing complex movements without trembling," said Lawrence Ho, the Singapore National University Hospital gastroenterologist who helped design the cyber-surgeon, described in an article published in the Journal of Gastroenterology and Hepatology. "The machinery – continued – we already have ‘helped to remove tumors in the stomach during the initial five patients in India and Hong Kong. The operations have required less time to run, putting patients at lower risk of incurring infections and letting it heal quickly. We used the Crab as a prototype with its strong pincers can collect the sand, according to human anatomy and ideas borrowed from nature. " The researchers have formed a company ‘last October, hoping to make the robot commercially available in three years
