Chapter 341: Homologous

Chapter 341
Three brothers who have been introduced to general surgery, appendix, hernia, gallstones. These three operations are not very difficult, but the number of patients is large, so this operation is also a basic operation considering the general doctor. After the doctor has been in the general surgery department for a while, the superior doctor will observe whether the doctor has talent Whether or not, the touchstone is these three operations.
Lu Shuyan did not turn to the general public, that is, she stayed for a month during the internship. She was purely to pull hooks because the amount of surgery on the farm was relatively small and had been directly abandoned by the equipment manufacturer. Zhang Fan, they can only do surgery in the usual way.
Surgery with new materials, other than honest surgery, not only has a low recurrence rate, but also saves time. The conditions are limited, and only honest surgery can be used.
"Alcohol!" Zhang Fan said to Baoyin. Zhang Fan took the alcohol cotton ball and wiped it repeatedly on the skin to be cut. Although there are differences in the human body, the relative differences are not too great.
Therefore, almost every surgery has a fixed model, and this model has also been determined after a lot of choices. For hernia, for example, its standard incision is three centimeters above the inguinal ligament.
Zhang Fanliso cut open the skin, revealing the superficial fascia and fatty layer. Healthy people, as long as they have special organs or pipes, must have protection mechanisms.
The groin, as the name suggests. Men and women here use a lot of control. The ureters, fallopian tubes and spermatic cords all walk here. Cut the superficial fascia and ligate the superficial artery.
Zhang Fan has a habit, which he learned while in Jade Bird. As long as it is not a life in crisis, the operation must be carried out step by step and carried out in a hierarchical manner. It will not deliberately pursue speed. Surgery is not a fast drive.
Zhang Fan's surgical field of vision looks very clean. As long as there is bleeding, Zhang Fan will ensure that the surgical field is clear, whether it is ligating or using an electric knife to stop bleeding. Lao Hu is on tour. Although he has not undergone much surgery now, his vision for decades is still there.
"Dr. Zhang, you have a lot of effort under your hands. It is estimated that at least three or four hundred open surgery have been done."
"Oh, almost." Zhang Fan smiled, did not deny or admit it. People's eyes are put here, there is no need to deceive others.
Although in reality Zhang Fan does not have three hundred laparotomy operations, but in the system, Zhang Fan estimates that there have been thousands of them. So many operations, even a monkey, are expected to look a little bit like that!
Entering the superficial fascia, Zhang Fan's fingers wrapped around the gauze and began to bluntly separate. The so-called blunt type of separation actually has the biggest advantage of less damage. Because after entering the superficial fascia, there is first a layer of tissue like a plastic film, and the walkers inside are very rich in capillaries.
Separating the fascia is the muscle. Most of the muscle's functions are accomplished by contraction, and the friction is more severe, so there is a thin coat on the muscle surface.
And the muscles are like beef, with obvious texture. When you do not need a sharp weapon to disconnect, you must not disconnect. Because after the muscle is broken off, it is no longer the muscle that produces the scar tissue. Scar tissue not only has poor blood flow, but also has less flexibility and firmness than muscle.
Zhang Fan used scissors to cut a small mouth along the texture of the muscle coat, and then Lu Shuyan reached into her hand. This is where the assistant and the main knife work together.
The meaning of inserted into a small hole, one is a protective plate, because then Zhang Fan will use scissors to cut all the muscle coats along this small mouth along the muscle texture.
The second meaning is to hold up the space and make it easier for Zhang Fan to operate. It's not that insiders are very difficult to understand this action. In fact, it's simple.
For example, take off the girl ’s clothes and not take them off all at once, or the girl will definitely resist, and she ca n’t be anxious. Singles usually ca n’t do this operation because he does n’t understand!
This must be solved step by step. And at this time, the hands can't touch the skin of other girls, just like the reason that Zhang Fan can't cut the muscles with his scissors at this time.
When you are dating, if you take off your partner ’s coat, will you be done? It's too early, so is the operation. The muscle layer, including the muscle layer, is not a very difficult tissue, so surgery is just the beginning.
Lu Shuyan was a little anxious. After all, the girl was not a general doctor. Sometimes, if she didn't do well, she needed to mention something. The more the operation was done, Zhang Fan also started to have some problems. Common problems of a surgeon.
He thinks it is very simple, but when Lu Shuyan or other doctors can't do it, these surgeons are anxious. Whether it is a doctor with a good temper or not, almost all have this problem.
"Oh!"
"Knot!"
"Where is the attractor!" Zhang Fan said with a tone of anxiety. As soon as Zhang Fan was anxious, Lu Shuyan was even more anxious. After all, she was not very skilled in this operation.
"Dr. Lu, don't worry, you follow Dr. Zhang's hand. If you can't judge his next step, your hand will follow his hand, always keep the attractor or hook to follow him, and then spare a hand, ready to support "You are already very good. Don't worry" Lao Hu said a little anxiously when he looked at the girl.
After all, the old guy has been immersed in the medical industry for decades, and some small means are still very powerful. A slight mention is that Lu Shuyan has done a lot smoother.
"Thank you, Mr. Hu." After that, he rolled his eyes at Zhang Fan, but it was very fast. On the operating table, Zhang Fan was like a person.
The muscles that enter the first layer should be fixed at this time. How to fix it is to use hemostatic forceps to pull apart the separated muscles, leaking deeper layers. Dating experts generally understand, take off your coat, and throw away a little bit, or you can't make the girl put it on again, in fact, the same principle is the same.
Continue, what is the internal oblique, transverse abdominal, and external oblique. The muscles of the human body are like people in the winter. They have sweaters in sweaters, sweaters in sweaters, and various horizontal and vertical clothes in the sweaters. Really, think about this stuff and human clothes too.
The muscle layers are all open and important tissues are here. The sperm has come out. Westerners know how late the kidneys are related to sex, and the Chinese people, who do not know which clever guys, have proposed the principle of solidifying the kidneys first. In fact, during the embryonic period, the kidney and this were actually developed by a cell, and then at the end, when the boy was about to give birth, the did not move.
This is why, clearly below, the sperm-transportable channel hangs high with the ureter. Because, felt that the abdomen was too hot, and could not stand it and came down from the stomach.
When Zhang Fan separated the cremaster muscle and free spermatic cord, he remembered the old head's look of fear at the time, and even laughed. "What are you laughing at?"
Zhang Fan laughed, and Lu Shuyan dared to speak. It's too much to help the little girl, and she can't even speak.
Zhang Fan ignored Lu Shuyan, but instead asked Dr. Hu: "Mr. Hu, how many children is the old head."
"Two sons, hey!"
"What's wrong, how can you sigh." Zhang Fan asked wonderingly, he rarely gossip.
"The old head's young son, graduated from college. The old head wanted to send the younger son to the border, but the young son didn't listen and went abroad. Because of this matter, the old head didn't let the young son enter the house. This old man is too shy . His youngest son, the poor one who cried when he left, the old man stiffly didn't let the child enter the door, and the baby finally knelt down on the street with three heads facing the door and walked away with tears. That heart is so sad, let alone old ladies, a lot of old men are crying, looking at the grown up child that sad! "
"amount!"
"The child's mother was frozen to death on the snow line. It may have affected the child too much.
"Oh."
