Choledochoscope

Ling Ran stood at the chief surgeon's position by the operating table. Zhang Anmin was at the first assistant's position, Ma Yanlin stood at the second assistant's position. All of them were fully immersed in their tasks. 

The patient on the operating table was covered with green drapings. His face and hands were not visible. Only his abdomen was exposed, specifically for access to his liver. 

Zhang Anmin gasped for breath and watched as Ling Ran broke off a small piece of liver.

He had actually performed quite a number of liver surgeries. If he did not include the time where he had been a second assistant, ever since becoming a senior resident doctor, he had performed eighty to one hundred of hepatectomy surgeries as the first assistant.

It could be said that he was very excited during the first few hepatectomies he performed. But after performing twenty to thirty cases, that fire quickly simmered down.
