Chapter 1199 Don't Panic

"The great saphenous artery is stripped, let's start directly." Ling Ran re-selected his position and came to the patient's leg.

Observing the patient in front of him with the "perfect level" great saphenous vein dissection, he can easily analyze the direction and state of the great saphenous vein.

Of course, the specific location still depends on the previous video.

These are very basic steps. In order to ensure the smooth success of his first great saphenous vein stripping operation, Ling Ran also took out a 3-second virtual human without any hesitation—cut it from head to tail with one knife, and cut it off on the spot. Take out the great saphenous vein, and test the flexibility by the way, which can be said to be a very rough test method.

After completing this step, he was completely relieved.

That's right, the patient in front of him is a standard normal human being on earth, and he can be said to be stable with his own technology.

A smile appeared on the corner of Ling Ran's mouth, he was very satisfied with the situation in front of him.

Being a surgeon is not always as sure as it seems. However, when it comes to small knives, they are very decisive.

It is impossible to be indecisive. The operation must continue, and repeated hesitation will not make the situation better.

However, it would be better if there was more information and the situation could be truly ascertained.

Ling Ran felt that the current state was pretty good.

He has the feeling that everything is ready, and he feels fresh about the operation in front of him.

This is a rare experience. In normal times, everyone has to do the surgery that they are familiar with, so that they can have this sense of security and control that everything is ready.

But it is too difficult to match it with "fresh" for adjustment.

Ling Ran decided to enjoy today's operation to the fullest.

"Knife." Ling Ran reached out and picked up an electric knife into his palm.

The little doctor who served as his foil looked at Ling Ran strangely.

Ling Ran's dancing movements just now are obviously very special. If it wasn't for Ling Ran's handsome appearance and reputation, he would have regarded it as an act of a great dancer.

Of course he doesn't dare to talk nonsense now, but the little doctor still asked cautiously: "Doctor Ling, why did you dance your hands in mid-air just now.

"

"Didn't touch the polluted area." Ling Ran's way of thinking was completely different.

The little doctor hurriedly said: "No, I just think that your movement is quite special, and it looks good, a bit like dancing?"

"Dancing doesn't matter." While Ling Ran was speaking, he lowered his head and scratched to open the skin of the patient's legs.

He chose the side of the blood vessel near the arch of the foot, which is rich in blood vessels, and even if one is removed, it will not affect the normal life of the patient.

The residents of the Cardiac Surgery Department also often accompanied the surgery, and one could tell from Ling Ran's movements that Ling Ran was very confident.

This made the little doctor look at Ling Ran even more strangely, and said in his heart: He is so handsome, not only his movements are good-looking, but his confidence in performing surgery seems to be stronger than others.

The nurse who was cooperating with Director Kang couldn't help but cast a few glances over, and couldn't help saying, "Dr. Ling's movements are really beautiful, can Dr. Ling dance?"

Director Kang said unhappily: "Whether you can dance or not has nothing to do with the operation of the operation. You should perform the operation well."

"Yes, Director, we are all doing the operation well. We are not worried that Dr. Ling is not used to using our things." The little nurse found a reason to prevaricate Director Kang.

The director can't help it. Unless the operation is so bad that he gets angry, Director Kang won't pull down his face and scold the nurse.

Director Kang could only shake his head and speak in Ling Ran's language: "Don't interfere with Dr. Ling's operation. No matter how thick the big Yin is, it's still a blood vessel. If it gets mixed with the nerves, it will be easily torn."

"Director, don't be scary. We have performed so many operations with you, and the blood vessels that get mixed up with the nerves are less than 20%."

"It's like 10 to 20 percent." The itinerant nurse next to him spoke up.

"Besides, Dr. Ling's skills are so good, and his luck is so good, he will definitely not encounter such trouble..."

"It's said in the horoscope book that handsome people will not have bad luck."

Director Kang rolled his eyes when he heard this, but it would be unwise to argue with married women when they are united. It would be very dangerous even for a direct superior to do so, not to mention Director Kang's authority in the department is not that heavy.

Director Kang shook his head, and while processing the work in hand, he said: "In your horoscope book, there is no mention of how to avoid this situation?"

"Don't perform surgery at night, it is easy to have a crisis when the planets are connected."

"You can't do surgery at noon, the sun will affect your luck."

"It's not suitable for surgery in the morning, because..."

"It's not suitable for the whole day?" Director Kang laughed twice, and said: "Let me put it this way, I would rather have my nerves..."

"It's a bump." Ling Ran responded, reporting the situation during the operation to the chief surgeon.

Director Kang was stunned for a moment: "Have we met?"

"Well, there is a nerve winding around this great saphenous vein." Ling Ran confirmed.

"I hit a nerve at the beginning..." Director Kang raised his head, looked towards Ling Ran, and suddenly found that a long blood vessel had been pulled up.

Stripping blood vessels is easy to say, but requires careful work. To put it simply, it is to cut open the outside of the blood vessel along the direction of the vein to expose the blood vessel, and then peel off the surrounding small blood vessels one by one, the core of which is to ligate the interface.

Imagine the great saphenous vein as a main road, and the process of stripping it off is the process of blocking all auxiliary roads.

The difficulty of this process is not high, and ordinary minor treatments can be completed smoothly, but in terms of speed, even a veteran director who has been working for many years may not be able to do it quickly and well.

Director Kang was busy with his own work just now, and deliberately slowed down, waiting for Ling Ran to practice his skills. He believed that Ling Ran would be able to successfully complete the blood vessel harvesting - it would be easy for a doctor who can perform liver resection to do this, but it was a surprise that he managed to do so so quickly.

"Doctor Ling, where did you practice this trick..." Director Kang was full of doubts. Don't they go to other hospitals, practice the skills, and then come back to export and sell domestically?

The more Director Kang thought about it, the more likely it was, and his expression became more serious.

Ling Ran briskly peeled the nerve with his fingers. For the consideration of the postoperative life of the patient, it is very necessary to preserve the nerve. But to keep it, you can only deal with it a little bit carefully.

Director Kang looked serious, turned his head around with great difficulty, and heard the attending power whisper: "It seems to be no-touch."

"Huh?" Director Kang hurriedly turned his head.

The so-called no-touch means that in the process of obtaining the great saphenous vein, the great saphenous vein is not touched, but about 1 cm of surrounding tissue around the great saphenous vein is preserved.

The advantage of this is that it reduces the damage to the vein and avoids the occurrence of venous spasm. The three-layer hibiscus tissue of the entire vessel wall can also be preserved intact, thereby increasing the long-term inflation rate after transplantation.

Compared with the reports in the literature, the long-term patency rate of vein grafts is 50%, while the long-term patency rate of vein grafts obtained by no-touch technology can reach 85%, which is comparable to that of arterial grafts.

However, compared to the simple interception of the great saphenous vein, the no-touch technique is much more complicated. It is a complete technical system, and it is a relatively high-end technique that has not yet been developed by Yunyi Cardiac Surgery...

Seeing that he was still hesitating, whether the technique he wanted to learn was used by Ling Ran, Director Kang was in a very...panic!
