Three brothers who started general surgery, appendix, hernia, and gallstones. These three surgeries are not very difficult, but the number of patients is very large, so this surgery is also a basic operation to consider the general surgeon, after the doctor has been in the general surgery department for a period of time, the senior doctor will observe whether the doctor is talented, whether he is attentive, and the touchstone is these three surgeries.

Lu Shuyan didn't go to the general hospital, that is, she stayed for a month during the internship, and she purely came to pull the hook, because the amount of surgery on the farm is relatively small, and she has been directly abandoned by the instrument manufacturer. Zhang Fan: They can only operate in the usual way.

Surgery with new materials, not to mention other than honest surgery, not only has a low recurrence rate but also saves time, but the conditions are limited, so 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 during the operation. Although there are differences in the human body, the relative differences are not too great.

Therefore, almost every type of surgery has a fixed pattern, and this model is also determined after thousands of selections. For example, for hernias, the standard surgical incision is three centimeters above the inguinal ligament.

Zhang Fanlisuo's incision of the skin exposes the superficial fascia and fat layer. Healthy people, as long as there are special organs or pipes out of shape, there will be a protective mechanism.

Groin, as the name suggests. Both men and women use a lot of pipes to pass here. The ureters, fallopian tubes, and spermatic cord all walk here. The superficial fascia is incised and the superficial artery is ligated.

Zhang Fan has a habit that he learned when he was a bluebird. As long as it is not a life-threatening time, the operation must be carried out step by step, in a clear and hierarchical manner, and will not deliberately pursue speed, and the operation is not a fast train.

Zhang Fan's surgical field looks very clean, as long as there is bleeding, Zhang Fan will definitely ensure that the surgical field is very clear, whether it is ligation or electric knife to stop bleeding. Lao Hu is on tour, although he doesn't do surgery anymore, but his vision for decades is still there.

"Dr. Zhang, you have a lot of hard work. It is estimated that at least 300 or 400 laparotomy surgeries have been performed. ”

"Hehe, almost. Zhang Fan smiled, did not deny or admit it. People's eyes are here, there is no need to deceive them.

Although there are no 300 laparotomy surgeries for Zhang Fan in reality, in the system, Zhang Fan is estimated to have done thousands, and with such a number of surgeries, even if he is a monkey, it is estimated that he can look a little!

Entering the superficial fascia, Zhang Fan's fingers wrapped gauze and began blunt separation, the so-called blunt separation, in fact, the biggest advantage is that the damage is small. Because after entering the superficial fascia, there is first a layer of tissue like a plastic film, which is very rich in capillaries for walkers.

Dividing the fascia is the muscle, and most of the functions of the muscle are completed by contraction, and the friction is relatively strong, so the muscle surface has a thin coat.

And the muscles are like beef, they have a distinct texture. When there is no need for a sharp weapon to break off, it must not be broken. Because when the muscle is severed, it is no longer the muscle that is generated, but the hoof scar tissue. Scar tissue is not only poorly vascular, but also less elastic and firm than muscle.

Zhang Fan used scissors to cut a small opening along the texture of the muscle's coat, and then Lu Shuyan reached out and stuffed it in. This is where the assistant and the main knife work together.

The meaning of the two fingers stuffed into the small hole, one is to be used as a protective plate, because then Zhang Fan has to use scissors to cut all the muscles along the muscle texture on this small opening.

The second meaning is to prop 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 is also simple, to put it in layman's terms.

For example, if you take off a girl's clothes, you can't take them all off at once, otherwise the girl will definitely resist, and she can't be in a hurry, and she 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 in his hand at this time can't cut the muscles.

Normally, when you go on a date, if you take off the other person's coat, is it done? The muscle layer, including the muscle layer, is not a very difficult tissue, so the surgery is the beginning.

Lu Shuyan was a little anxious, after all, the girl was not an ordinary doctor, and sometimes, if she didn't do it properly, she still needed Zhang Fan to mention it, and the more the operation was done, Zhang Fan began to have some problems. A common problem of a surgeon.

He thinks it's very simple, but when Lu Shuyan or other doctors can't do it, these surgeons are in a hurry, whether they are usually good-tempered doctors or not, almost all of them have this problem.

"Pull the hook!"

"Tie the knot!"

"Where's the attractor!" Zhang Fan said and said in a slightly anxious tone, as soon as Zhang Fan was in a hurry, Lu Shuyan was even more anxious. But after all, she is not very skilled in this kind of operation.

"Doctor Lu, don't worry, you follow Dr. Zhang's hand. If you can't tell his next move, your hand follows his hand, always keeping the suction device or retractor following him, and then free hand, ready to support at any time. You're already amazing. Don't worry" Lao Hu looked at the girl a little anxious, and said softly.

After all, the old guy has been immersed in the medical industry for decades, and some small means are still very powerful.

"Thank you, Mr. Hu. After speaking, he rolled his eyes at Zhang Fan, but the speed was very fast, and on the operating table, Zhang Fan was like a different person.

The muscles that enter the first layer are to be fixed at this time. How to fix it is to use a hemostat to pull the separated muscles apart and leak out a deeper layer. Dating masters generally understand that if you take off your coat, you have to throw it away quickly, otherwise you won't be able to get the girl to put it on again, in fact, the principle is the same.

Continue, what internal oblique muscles, transverse abdominis muscles, what external oblique muscles. The muscles of the human body are like people in winter, the down jacket is covered with a sweater, the sweater is covered with a thread coat, and there are all kinds of horizontal and vertical clothes inside the thread jacket, really, think about it, this thing is too similar to human clothes.

The muscle layers are all opened, and the vital tissues are coming. The spermatic cord came out, and it was too late for Westerners to figure out the relationship between the kidney and **, and the Chinese people didn't know which smart guy had put forward the principle of consolidating the kidney early. In fact, in the embryonic period, the kidneys and this ** are actually developed as a cell, and then in the end, when the boy is about to leave the mother's womb, ** moves.

This is why, even below, the passage that transports sperm hangs high with the ureter. Because, ** felt that the abdomen was too hot, and he couldn't stand it and came down from the stomach.

When Zhang Fan separated the cremaster muscle and free the spermatic cord, he remembered the old leader's scared look at that time, and he actually laughed. "Laughing at what?"

Zhang Fan smiled, and Lu Shuyan dared to speak. It's really too much, and the little girl is at a loss, and she doesn't even dare to speak.

Zhang Fan ignored Lu Shuyan, but asked Doctor Hu: "Teacher Hu, how many children are the old leader." ”

"Two sons, hey!"

"What's the matter, why do you sigh. Zhang Fan asked in confusion, he rarely gossiped.

"The youngest son of the old leader, graduated from college. The old head wanted his youngest son to come to the frontier, but the younger son didn't listen and went abroad. Because of this incident, the old head of the regiment did not let his youngest son enter the house. This old man is too stubborn. His youngest son, when he left, the poor one who cried, this stubborn old man just didn't let the child enter the door, and the baby finally knelt on the street and kowtowed three times to the door, touching the tears and leaving. The sad one back then, not to mention the old ladies, many old men cried, looking at the sad children who grew up!"

"Huh!"

"The child's mother froze to death on the snow line, and it may have had too much impact on the child back then, and the baby just wanted to leave here. Hey!"

"Oh!"
