Medical road

The three brothers in the introduction to general surgery, appendix, hernia, and gallstones.These three operations are not very difficult, but the number of patients is very large, so this operation is also a basic operation for general surgery doctors. After the doctor has been in general surgery for a period of time, the superior doctor will observe whether the doctor is talented. , Whether you are careful, the touchstone is these three operations.

Lu Shuyan did not transfer to general surgery, that is, she stayed for a month during the internship. She was purely here to pull the hook, because the number of operations on the farm was relatively small and had been directly abandoned by the equipment manufacturer.Zhang Fan can only perform the operation in a conventional way.

Surgery with new materials, not to mention other than the honest operation, not only has a lower recurrence rate, but also saves time. However, the conditions are limited and only the honest operation can be used.

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

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

Zhang Fanli Suo cut the skin to reveal the superficial fascia and fat layer.Healthy people, as long as they have special organs or pipes that are out of shape, there must be a protective mechanism.

The groin, as the name suggests.Here both men and women use a lot of control over the road.The ureter, fallopian tube, and spermatic cord all walk here.Cut the superficial fascia and ligate the superficial artery.

Zhang Fan has a habit that he learned when he was at Jade Bird.As long as it is not a life-threatening time, surgery must be performed step by step, with a clear hierarchy, and will not deliberately pursue speed. Surgery is not a fast drive.

Zhang Fan's surgical field looks very clean. As long as there is bleeding, Zhang Fan will ensure that the surgical field is clear, whether it is ligation or electrocautery to stop the bleeding.Lao Hu is touring. Although he doesn't do much surgery now, he still has his vision for decades.

"Dr. Zhang, you have done a lot of work. It is estimated that you have done at least 300 or 400 laparotomy operations."

"Haha, almost." Zhang Fan smiled, neither denied nor admitted.People's vision is here, there is no need to deceive them.

Although in reality Zhang Fan does not have 300 laparotomy operations, in the system, Zhang Fan estimates that he has performed thousands of operations. With such a large number of operations, it is estimated that even a monkey will look a little bit!

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

Separating the fascia is the muscle. Most of the function of the muscle is done by contractility. The friction is relatively strong, so the muscle surface has a thin coat.

And the muscles are like beef, with obvious texture.When you don't need a sharp weapon to break off, you must not break off.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 along the texture of the muscular coat, and then Lu Shuyan reached out and stuffed it in.This is the cooperation between the assistant and the chief knife.

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

The second meaning is to prop up the space and make Zhang Fan easier to operate.It is not that insiders are very difficult to understand this action.In fact, it is also simple, to put it in a more popular way.

For example, taking off a girl’s clothes, you can’t take it off all at once, otherwise the girl will definitely resist, and you can’t be anxious. Single people usually can’t do this surgery because he doesn’t understand!

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

In general, if you take off your partner's coat, will you be done?Shit, it's still early, and surgery is the same.The muscle layer, including the muscle layer, is not a very difficult tissue, so surgery is the beginning.

Lu Shuyan was a little anxious. After all, the girl was not a general doctor. Sometimes, she didn't do the job well, and Zhang Fan needed to mention something. The more operations she performed, Zhang Fan started to have some problems.A common problem of surgeons.

What he thinks is very simple, but when Lu Shuyan or other doctors can't do it, these surgeons are anxious. Whether or not they have a good temper, they almost have this problem.

"Lago!"

"Knotted!"

"Where's the attractor!" Zhang Fan said with a little anxious tone. When Zhang Fan was anxious, Lu Shuyan became even more anxious.But after all, she is not very skilled in this kind of surgery.

"Doctor Lu, don’t worry, you follow Dr. Zhang’s hand. If you can’t judge his next step, follow his hand, keep the attractor or the hook and follow him, then free a hand, ready to support .You are already very good. Don't worry," Lao Hu said while looking at the girl a little worried.

After all, the old guy has been immersed in the medical industry for decades, and some small tricks are still very powerful. Just a little bit, Lv Shuyan does it much smoother.

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

The muscles that enter the first layer must be fixed at this time.How to fix it is to use hemostatic forceps to pull apart the separated muscles to leak a deeper level.Dating masters generally understand that if you take off your coat, throw it away quickly, otherwise the girl will put it on again. In fact, the truth is the same.

Go on, what is the internal oblique muscle, the transverse abdomen, and what the external oblique muscle.The muscles of the human body are just like people in winter. Down jackets are covered with sweaters, sweaters are covered with sweaters, and there are all kinds of clothes inside the sweaters. Really, think about this thing and human clothes too much.

The muscle layers are all opened, and important tissues are here.The spermatic cord came out, and it was so late for Westerners to figure out the relationship between the kidney and sex, and the Chinese, who didn't know which clever guy it was, put forward the principle of strengthening the essence first.In fact, during the embryonic period, the kidney and this *** actually developed in one cell, and then in the end, when the boy was about to give birth, the *** moved.

This is the reason why the sperm transport channel hangs high together with the ureter.Because I felt that my abdomen was too hot, and I got out of my belly if I couldn't stand it.

When Zhang Fan separated the cremaster muscle and freed the spermatic cord, he remembered how the old head was scared at the time, and he actually laughed."What are you laughing at?"

Zhang Fan smiled before Lu Shuyan dared to speak.It's too much, I'm at a loss for the little girl, and dare not even say anything.

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

"Two sons, hey!"

"What's wrong, why are you sighing?" Zhang Fan asked in a puzzled way. He rarely gossip.

"The youngest son of the old leader, graduated from college. The old leader wanted to let the younger son come to the frontier, but the younger son refused to listen and went abroad. Because of this matter, the older leader refused to let the younger son into the house. This old man is too stubborn. . His youngest son, when he left, the pitiful crying person, this stubborn old man did not let the child in. The baby finally knelt on the street and knocked three heads in front of the door, and walked away with tears. That sadness, let alone the old ladies, a lot of the old men are crying, the sad one watching the grown-up child!"

"amount!"

"The child's mother was frozen to death on the snow line. It may have had a great impact on the child back then. The child who is hanging on the bone just wants to leave here. Hey!"

"Oh!"
