Chapter 341

Three brothers, appendix, hernia and gallstone. These three operations are not very difficult, but there are a large number of patients. Therefore, this operation is also the basic operation of general practitioners. After the doctor has fixed the Department for a period of time, the superior doctor will observe whether the doctor has talent and intention. The touchstone is these three operations.

LV Shuyan didn't turn away from general education, that is, she stayed for a month during her internship. She just came to pull the hook. Because the amount of surgery on the farm is relatively small, she has been directly abandoned by the equipment manufacturer. Zhang Fan, they can only operate in the conventional way.

Compared with honest surgery, surgery with new materials not only has a low recurrence rate, but also saves time. But the conditions are limited, so we can only use honest surgery.

"Alcohol!" Zhang Fan said to Baoyin that Zhang Fan took the alcohol cotton ball and wiped it repeatedly at the skin to be cut during the operation. Although the human body is different, the relative difference is not too great.

Therefore, almost every operation has a fixed mode, which is determined after thousands of choices. For example, the standard incision for hernia surgery is three centimeters above the inguinal ligament.

Zhang fanlisuo's incision revealed the superficial fascia and adipose layer. Healthy people, as long as there are special organs or pipes out of shape, there will be a protection mechanism.

Groin, as the name suggests. Both men and women pass by in many pipes. Ureter, fallopian tube and spermatic cord all walk here. Cut the superficial fascia and ligate the superficial artery.

Zhang Fan has a habit, which he learned when he was a bluebird. As long as it is not a time of life crisis, surgery must be carried out step by step and in a clear hierarchy. It will not deliberately pursue speed. Surgery is not driving fast.

Zhang Fan's surgical field of vision looks very clean. As long as there is bleeding, whether it is ligation or hemostasis with an electric knife, Zhang Fan will ensure that the surgical field is very clear. Lao Hu is on tour. Although he doesn't do much surgery now, he still has his eyes for decades.

"Dr. Zhang, you are very skilled. It is estimated that at least three or four hundred laparotomies have been performed. "

"Oh, almost." Zhang Fan smiled, neither denying nor admitting. People's eyes are here. There's no need to deceive people.

Although there are not 300 open surgeries in reality, in the system, Zhang Fan estimates that he has done thousands of surgeries. Even if he is a monkey, it is estimated that he can look a little like a monkey!

After entering the superficial fascia, Zhang Fan wrapped his fingers around gauze and began blunt separation. The so-called blunt separation actually has the greatest advantage of less damage. Because after entering the superficial fascia, there is a layer of tissue like plastic film, which is rich in capillaries.

Separating the fascia is the muscle. Most of the functions of the muscle are completed by contraction. The friction is severe, so there is a thin coat on the surface of the muscle.

And muscle, like beef, has obvious texture. When you don't need a sharp weapon to disconnect, you must not disconnect. Because after the muscle is broken, it is no longer muscle, but hoof scar tissue. Scar tissue not only has poor blood supply, but also has worse elasticity and firmness than muscle.

Zhang fan used scissors to cut a small opening in the muscle coat along the texture, and then LV Shuyan reached out and stuffed it in. This is the cooperation between the assistant and the main knife.

Two fingers into a small hole means that one is used as a protective board, because Zhang Fan will use scissors to cut all the muscle coats along the muscle texture on the small mouth.

The second meaning is to prop up the space and make it easier for Zhang Fan to operate. It's not very difficult for insiders to understand this action. In fact, it's also simple. It's more popular.

For example, if you take off a girl's clothes, you can't take them off all at once, otherwise the girl will definitely resist. Don't worry. Single Wang can't do this operation well because he doesn't understand!

This must be solved step by step. And at this time, the hand can't touch the skin of other girls, just like Zhang Fan's scissors can't cut the muscle at this time.

If you take off your partner's coat during a general date, is it done? Shit, it's still early. So is the operation. The muscle layer, including the muscle layer, is not a very difficult tissue, so the operation is the beginning.

LV Shuyan is a little worried. After all, the girl is not a general practitioner. Sometimes she doesn't do well, and Zhang Fan needs to mention it. The more surgery she does, Zhang Fan also begins to have some problems. A common problem of an surgeon.

He thinks it's very simple, but when LV Shuyan or other doctors can't do it, these surgeons are worried. Whether they are doctors with good temper or not, they almost have this problem.

"Pull the hook!"

"Knot!"

"Where's the attractor!" Zhang Fan was a little worried when he spoke. As soon as Zhang Fan was worried, LV Shuyan was even more worried. But after all, she is not very skilled in this kind of operation.

"Dr. Lu, don't worry. 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 following him, and then spare a hand and be ready to support at any time. You're already great. "Don't worry," Lao Hu said softly, looking at the girl a little worried.

After all, the old guy has been immersed in the medical industry for decades, and some small hands are still very powerful. With a little help, LV Shuyan can do much more smoothly.

"Thank you, Miss Hu." Then he rolled his eyes at Zhang Fan, but the speed was very fast. On the operating table, Zhang Fan was like a person.

The muscles entering the first layer will be fixed at this time. How to fix is to use hemostatic forceps to pull apart the separated muscles and leak deeper. Dating experts generally understand that if you take off your coat, you have to throw it away, otherwise you can't get the girl to put it on again. In fact, this principle is the same.

Go on, what internal oblique, transverse abdominal, what external oblique. The muscles of the human body are like people in winter. There are sweaters in down coats and thread clothes in sweaters. There are all kinds of clothes in thread clothes. Really, think about it. It's so similar to people's clothes.

All the muscle layers are open and important tissues are coming. The essence came out. It was so late for westerners to find out the relationship between kidney and * *, and the Chinese did not know which clever guy had put forward the principle of consolidating essence and kidney early. In fact, in the embryonic stage, the kidney and the * * actually develop in one cell, and then in the end, when the boy is about to leave the womb, * * moves.

That's why the passage that can transport sperm is hanging high with the ureter. Because * * felt his stomach was too hot and couldn't stand it, so he came down from his stomach.

When Zhang Fan separated the testicular muscle and dissociated the spermatic cord, he thought of the old head's fear at that time, and finally smiled“ What are you laughing at? "

Zhang Fan smiled and LV Shuyan dared to speak. It's too much. I'm so overwhelmed that I don't even dare to say anything.

Zhang Fan ignored LV Shuyan and instead asked Dr. Hu, "Mr. Hu, how many children are there?"

"Two sons, ah!"

"What's the matter? Why do you sigh?" Zhang Fan asked in wonder. He seldom gossips.

"The youngest son of the old colonel, graduated from college. The old leader wanted his little son to come to the frontier, but the little son didn't listen and went abroad. Because of this, the old regimental commander refused to let his little son into the house. The old man is too stubborn. His youngest son, when he left that year, cried pitifully. The stubborn old man stubbornly didn't let the child in. At last, she knelt down in the street, kowtowed three heads to the door and walked with tears. I was so sad, not to mention the old ladies. Many old men cried and looked at the sad children who grew up! "

"Well!"

"The child's mother was frozen to death on the snow line. It may have had a great impact on the child in those years. The child's deep-rooted intention is to leave here. Ah! "

"Oh!"
