Three brothers who are familiar with general surgery: appendix, hernia, and gallstones. These three operations are not very difficult, but the number of patients is large, so this operation is also a basic operation for general surgery doctors. After a doctor has been admitted to the general surgery department for a period of time, the superior doctor will observe whether the doctor has talent. , the touchstone of whether one is careful or not is these three surgeries.
Lu Shuyan had never transferred to general surgery, that is, she only stayed for a month during her internship. She was purely here to pull hooks. Because the farm's operation volume was relatively small, the equipment manufacturer had directly given up on it. Zhang Fan and the others can only perform the surgery using conventional methods.
Surgery with new materials, among other things, has a lower recurrence rate than traditional surgery and is also very time-saving. However, due to limited conditions, traditional surgery can only be used.
"Alcohol!" Zhang Fan said to Baoyin. Zhang Fan took the alcohol cotton ball and wiped it repeatedly on the skin to be incised during the operation. Although the human body has differences, the relative differences are not too great.
Therefore, almost every type of surgery has a fixed model, and this model is also determined after thousands of choices. For example, the standard incision for hernia surgery is three centimeters above the inguinal ligament.
Zhang Fan neatly incised the skin to expose the superficial fascia and fat layer. Healthy people will definitely have protective mechanisms when special organs or pipes become deformed.
The groin, as the name suggests. Both men and women use many pipes to pass by here. The ureters, fallopian tubes, and spermatic cord all travel here. The superficial fascia was incised and the superficial artery was ligated.
Zhang Fan has a habit that he learned when he was in Jade Bird. As long as it is not a life-threatening situation, the operation must be performed step by step and in a clear-cut manner, without deliberately pursuing speed. Surgery is not about speeding.
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 he performs ligation or uses electrosurgery to stop the bleeding. Lao Hu is on tour, and although he doesn't do many surgeries now, he still has the vision of decades.
"Dr. Zhang, you are very diligent. I must have performed at least three to four hundred laparotomies."
"Haha, almost." Zhang Fan smiled, neither denying nor admitting. People’s vision is here, there is no need to deceive others.
Although Zhang Fan did not perform more than 300 laparotomy surgeries in reality, in the system, Zhang Fan estimated that he had performed thousands of surgeries. With such a large number of surgeries, even a monkey would probably be able to do something!
After entering the superficial fascia, Zhang Fan wrapped his fingers with gauze and began blunt dissection. The biggest advantage of so-called blunt dissection is that it causes less damage. Because after entering the superficial fascia, the first thing is a layer of tissue like a plastic film, which contains very rich capillaries.
The separated fascia is the muscle. Most of the functions of the muscle are accomplished by contraction. The friction is relatively severe, so the surface of the muscle has a thin coat.
And the muscles are just like beef, with very obvious texture. When there is no need for sharp tools to disconnect, it must not be disconnected. Because after the muscle is severed, what is generated is no longer muscle but hoof scar tissue. Scar tissue not only has poor blood supply, but also has poorer elasticity and firmness than muscle.
Zhang Fan used scissors to cut a small opening on the muscle's coat along the texture, and then Lu Shuyan stretched out her hand and stuffed it in. This is the cooperation between the assistant and the surgeon.
The purpose of stuffing two fingers into the small hole is to serve as a protective plate, because next Zhang Fan will use scissors to cut open all the muscle coats along the texture of the muscles in the small opening.
The second meaning is to hold up the space and make it easier for Zhang Fan to operate. It is very difficult for people not in the industry to understand this action. In fact, it’s simple, to put it in a layman’s terms.
Just like taking off a girl's clothes, you can't take them all off at once, otherwise the girl will definitely resist. Don't be anxious. Singles generally can't do this surgery because they don't understand!
This must be solved step by step. And at this time, his hands can't touch the girl's skin, just like the scissors in Zhang Fan's hand can't cut the muscles at this time.
Normally on a date, if you take off the other person's coat, is it done? Damn, it’s still very early, and the same goes for surgery. The muscle layer, including the muscle layer, is not a very difficult tissue, so the surgery is just the beginning.
Lu Shuyan was a little anxious. After all, the girl was not a general surgery doctor. Sometimes, she did not do the job well, and Zhang Fan needed to give some advice. The more surgeries he performed, Zhang Fan began to have some problems. A common problem among surgeons.
He thought it was very simple, but when Lu Shuyan or other doctors couldn't do it, these surgeons became anxious. Regardless of whether they were doctors with a good temper or not, they almost all had this problem.
"Pull the hook!"
"Tie a knot!"
"Where's the attractor!" Zhang Fan sounded a little anxious as he spoke. When Zhang Fan was anxious, Lu Shuyan became even more anxious. But after all, she was not very skilled in this kind of surgery.
"Doctor Lu, don't worry, just follow Dr. Zhang's hand. If you can't judge his next step, follow his hand, always keep the suction device or retractor following him, and then keep a free hand, ready to support at any time. . You are already very powerful. Don't worry." Lao Hu saw that the girl was a little anxious and said softly.
After all, the old guy has been immersed in the medical industry for decades, and some small tricks are still very powerful. With a little reminder, Lu Shuyan's work became much smoother.
"Thank you, Teacher Hu." After saying that, he rolled his eyes at Zhang Fan, but he did it very quickly. On the operating table, Zhang Fan seemed to be a different person.
Entering the first layer of muscles will be fixed at this time. How to fix it is to use hemostatic forceps to pull the separated muscles apart to expose the deeper layers. Dating experts generally know that if you take off your coat, you have to throw it away quickly, otherwise the girl will put it on again. In fact, the principle is the same.
Moving on, what are the internal obliques, transversus abdominis, and external obliques. The muscles of the human body are just like people in winter. A sweater is put on a down jacket, a sweater is put on a sweater, and there are all kinds of clothes inside the sweater. Really, if you think about it carefully, these things are so similar to human clothes.
The muscle layers are all opened, and important tissues are revealed. After the spermatic cord came out, it was very late for Westerners to figure out the relationship between the kidneys and the vagina. However, the Chinese, I don’t know who is a very smart guy, put forward the principle of consolidating the sperm first and consolidating the kidneys long ago. In fact, during the embryonic period, the kidneys and the vagina develop from the same cell, and finally, when the boy is about to leave the mother's womb, the vagina moves.
This is why, although the vagina is clearly underneath, the channel that can transport sperm hangs high together with the ureter. Because, ** felt that her abdomen was too hot, and she couldn't bear it anymore, so she came out of her abdomen.
When Zhang Fan separated the cremaster muscle and freed the spermatic cord, he remembered how scared the old team leader was at that time, and actually laughed out loud. "What are you laughing at?"
Zhang Fan smiled, and Lu Shuyan dared to speak. It was so outrageous that the little girl was so helpless that she didn't even dare to say anything.
Zhang Fan ignored Lu Shuyan and instead asked Dr. Hu: "Teacher Hu, how many children does the old group leader have?"
"Two sons, hey!"
"What's wrong? Why are you sighing?" Zhang Fan asked in confusion. He rarely gossiped.
"The youngest son of the old regiment leader graduated from college. The old regiment leader wanted his younger son to come to the frontier, but the younger son refused and went abroad. Because of this, the old regiment leader stopped letting his youngest son enter the house. This old man is too stubborn. .His youngest son was so pitiful when he left that year. The stubborn old man refused to let the child in. In the end, the child knelt on the street and kowtowed to the door three times before leaving in tears. That year It’s so sad, not to mention old ladies, a lot of men cried, it’s sad to see the children growing up!”
"Forehead!"
"The child's mother froze to death on the snow line. It may have had a great impact on the child, and she was so worried that she wanted to leave here. Hey!"
"oh!"
