   Now the teacher has not given any instructions, so I can only try to keep my composure.

   The opposite student Geng Yongzhe was very patient, he didn\'t ask, just waited.

  Compared with other boys in the class, Geng Yongzhe really stands still when he does not move. This kind of dumbness is not even comparable to the squad leader of the boring gourd.

   Xie Wanying vaguely felt that Geng should be a person with super perseverance.

In front of   , the hand of the chief surgeon must first touch the lower uterus to determine the position of the fetal head. The experienced Director Yu mumbled, "Not very good."

   When the others heard the words of the chief knife, their nerves must not be tense. Assistant Dr. Peng\'s hand was placed at the end of the palace first to assist the main surgeon.

   "Don\'t be nervous." Director Yu said to his assistant on the ground.

   The director must be a big guy as well. Director Yu is more stable than Teacher Li, and so far he has only spoken in a slow, slow-paced tone.

   Director Yu\'s scalpel cut through the uterine wall, only about three centimeters, and then cut the amniotic membrane with surgical scissors, replaced the suction device, and sucked the amniotic fluid inside to prevent the umbilical cord from being flushed out by the amniotic fluid and causing fetal suffocation. When the suction is almost done, use both hands to tear the incision to 10 cm, and the uterine wall and the uterine muscle fibers are in the same direction, so that tearing is easier and less damaged than incision.

  You can see the black hair of the fetus.

   "Hey." Dr. Peng couldn\'t help but sighed.

   It can be seen that this situation is not very good. Why is it not so good?

  Maybe in the imagination of outsiders, cesarean section operation is to open the pregnant woman\'s belly, and the entire fetus is exposed to the doctor\'s field of vision, and the doctor easily lifts the fetus out.

  Reality has never been so simple and perfect, especially medicine. You need to be clear that cutting a pregnant woman\'s belly is not to remove the entire belly, but to open a hole. It\'s like a bag of things, when you open it, you can only see part of the contents. In order to maintain the integrity of the contents of the bag, care must be taken to prevent damage to the entirety of the item during pulling out of the bag. It is best that the mouth of the bag is large enough and the objects inside are small enough, so that it is the easiest to pull out. The most favorable conditions for cesarean section cannot exist. It is impossible for a doctor to cut the uterine wall of a pregnant woman as hard as possible. He must help the patient to reduce the uterine incision as soon as possible and minimize the damage to the uterus, so as to give the pregnant woman a chance to get pregnant next time. The pregnant uterus is mainly expanded by the fetus and amniotic fluid, so it is impossible for the fetus to be very small.

  Since the above two best conditions are impossible in reality, the doctor has to think of the best condition for pulling out the fetus. what is it? Think about the opening of the bag, and the things in it are just in the position where the hands are the easiest to pull out, and it is easiest to pull things out at this time. Since the general fetal position during childbirth is head down into the pelvis, the conventional transverse incision is set at three or four centimeters above the pubic bone, and many mothers\' uterus is opened at this position to expose the fetal ear or the back of the pillow. At this time, it is easier for the doctor\'s hand to hold the fetal head and take the fetus out of the mother\'s body.

   These are general situations, what to do in case of special cases. Some doctors judge that the fetus is difficult to take, and will directly take longitudinal incision or expand the incision into a T-shaped incision.
