   Anyway, listen to the teacher\'s arrangement.

   Wash your hands before surgery and re-enter the operating room, ready to stand next to the teachers to observe.

  Same as traditional surgery, sterilization and laying of sheets, the difference is that pneumoperitoneum must be established first for laparoscopy. Cut a small opening on the umbilicus and insert it into the trocar, inject an appropriate amount of CO2 gas into the abdominal cavity, inject the gas to a certain amount and connect the insufflator to maintain the pressure. At the same time, the monitor screen will show the situation in the patient\'s abdominal cavity.

   Then insert the cannula below the left and right mid-abdomen and above the pubic symphysis. Surgical instruments such as an ultrasonic knife should be placed in these sleeves. Laparoscopic surgery generally three doctors. In addition to the main knife and a helper, there is a special mirror hand.

   The mirror hand, as the name suggests, is to take the laparoscope to show the main surgeon the surgical field of view. The main knife generally operates the ultrasonic knife, and one assists the operation of the main knife with other instruments, such as a curved forceps suction device.

   In this way, the division of labor between laparoscopic surgery and traditional surgery has similarities and differences.

   Today\'s surgery is especially for low rectal tumors, and laparoscopic surgery is not very easy to operate. The students standing in the corner looked forward to the miracle of the tech giant.

   Liu Chengran, who continued to be the first assistant, helped the chief surgeon establish pneumoperitoneum and inserted a laparoscope into the patient\'s abdominal cavity.

   A color picture of the patient’s abdominal cavity immediately appeared on the monitor. The laparoscope saw the outside of the intestine, which was different from the digestive endoscope going inside the intestine. Therefore, it can be seen that the intestines in the patient are faintly peristalizing.

  The laparoscope was then handed over to the chief surgeon for abdominal exploration. Like traditional surgery, exploration is done to determine if the tumor can be removed and how much to remove.

   Holding the laparoscope, Tan Kelin looked at the monitor screen and said to someone behind him, "Stand up a little bit."

   Every move of the main knife attracts everyone\'s attention.

   All the students in the operating room heard the chief surgeon calling for someone to come up, and immediately saw Xie Wanying walking up to watch the monitor screen with the chief surgeon.

  The inside of the students immediately exploded:

"who is she?"

   "Resident physician?"

   "It\'s the doctor in this hospital, it should be."

   "It can\'t be a trainee or an intern."

   "Female doctor?"

   "Why was a female doctor called up by Dr. Tan?"

   One by two, they whispered, forgetting the order to silence, as if they were stimulated a lot by this scene.

  Luo Yanfen, Li Wenhao and the three of them were even more stunned: What is the teacher wanting this rookie to do? The problem is that they don\'t think that such a young Xie Wanying can have rich clinical skills enough for Tan Kelin to ask her what to do.

   "Speak again!" Sun Yubo turned back and roared impatiently at those who spoke.

   When will the quiet operating room become a vegetable market? !

   All the shouting stopped for a second.

   The operation room returned to dead silence.

  The attention of the students returned to the progress of the operation.

   The monitor screen shows the scene of the laparoscopic view moving in the patient\'s abdominal cavity. Sometimes the screen changes quickly, sometimes slowly.

   is not a teaching demonstration. Without the teacher explaining it, it is difficult for the students to fully understand the situation on the screen.

  Luo Yanfen and Zhang Zhongqiang asked Li Wenhao, who was in charge of the 7th bed, with inquiring eyes: Did you see anything?

  Li Wenhao shook his head.
