   "I have something to say." Xie Wanying thought clearly and raised her hand.

   There may be some things that Brother Tao is not very easy to say, so let her say it.

   The others looked at her, wondering what she could say at this moment.

   "Okay, you say." Zhang Huayao turned his head and pointed at her.

"The biggest disadvantage of full laparoscopy in this operation is that the operation is too complicated. If you follow the steps of laparoscopic surgery, it is more time-consuming than traditional surgery, which means that the main surgeon is not enough. Therefore, I suggest that in this full Adding a chief surgeon to laparoscopic surgery greatly shortens the operation time." Xie Wanying said.

   The doctor present could only be stunned when she heard what she said: Double main knife?

   "You mean this dual main sword?" Section Chief Yang frowned, not because she thought she was talking nonsense. After all, she had seen her hands-on ability and trusted her talent a bit. It\'s just that the concept of this dual main knife is indeed a bit deviating from practice.

   "It\'s not like there is a double main surgery." Fang Xueqing, who is not a surgeon, knows this surgical past, and recounts, "But it has not been popularized. Double main surgery has no advantage over a single main surgery."

  In traditional laparotomy, there is only one incision. If the surgeon\'s two hands go in to operate, it almost fills the surgical area, and there is no room for another person\'s hands. Besides, what\'s the matter? Ten fingers are enough for the doctor in charge.

  Because the doctor\'s hand is the biggest weapon in surgery. In the open abdominal cavity of the patient, the doctor\'s hand can change the angle as he wants, and the fingers can move as they want. The ten fingers of human beings are flexible and ingenious, and they are far inferior to any equipment, so there is no need to use double main knives. The words of the two main swords are rather messy.

   However, laparoscopy may be different.

  This epoch-making new technology developed on the basis of traditional surgery with the help of other technological revolutions has its own characteristics that are very different from laparotomy.

In the face of other people\'s doubts, Xie Wanying began to talk: "Laparoscopy is a surgical doctor\'s hand-held instrument to enter the patient\'s abdominal cavity through the operation hole, and the instrument is used instead of the doctor\'s hand to perform surgical operations. The surgical instruments basically have a single function, and the main surgeon wants to change the operation. It may be necessary to replace the surgical instruments when the operation is performed. The instruments retreat and advance in the operation hole, which will delay a lot of time. If the operation is successful, the operation time will be ample, which allows the doctor to make various attempts to solve the problem. The most afraid of encountering emergency situations, such as sudden There is a lot of bleeding and there is nowhere to find the bleeding. In this case, the doctor does not have the time on weekdays, so he can only quickly switch to open surgery."

  Others listen: Mmmm, that\'s exactly what she said. These are the disadvantages of laparoscopy. Many laparoscopic surgeries are urgently converted to laparotomy based on such circumstances and reasons. Therefore, for a long time, hepatobiliary surgery did not dare to perform laparoscopy even for liver cancer. Who made the liver cut too easy to bleed heavily? Doctors can\'t react with only surgical instruments.

   Question, can adding a doctor as the chief surgeon really solve this problem?

Xie Wanying continued to analyze the characteristics of laparoscopy: "The operating hole is fixed, if the chief surgeon has only one person, he is standing in a fixed position, and he wants the instruments in each hand to go in and cooperate with each other well, because the angle is fixed from a certain aspect. There is no way to freely cooperate with the two hands of the doctor in laparotomy. Not to mention that the human hand can bend freely, and no surgical instrument can bend and bend like the human hand. Therefore, if a chief surgeon is added, Standing in the opposite position can solve this operating angle problem very well."
