Under the watchful eyes of everyone, Yang Ping began to operate on pigs, Song Zimo and Xu Zhiliang as assistants, and the ultrasound department sent a doctor to control the color ultrasound machine, and the operation needed to be carried out under the monitoring of esophageal color ultrasound.

Conventional surgery involves a thoracotomy that involves a longitudinal incision of at least 15 to 20 centimeters from the sternum with a chainsaw, followed by a ribcage to cut through the thick aorta and into the left ventricle. During the procedure, the heart needs to be stopped, and cardiopulmonary bypass is used.

Yang Ping's new surgery does not need to make such a big move, only need to make a 5 cm small incision in the intercostal space of the left chest, use this small incision to enter the chest cavity, and then make a small infusion through puncture at the apex of the heart, and place an electric rotary knife.

Other cavity structures in the human body can basically be operated on with an endoscope, but the heart cannot, the heart is full of blood, and the endoscope can see nothing in the blood except a piece of red.

In order to allow the rotary knife to enter the left ventricle to operate under "visibility", it needs esophageal color ultrasound to function, its probe enters from the mouth, and Ran always enters the esophagus, which can observe the heart behind the heart.

Because it is closer to the heart and there is no bone to block it, the image will be clearer than if it is transchest ultrasound, the chest wall is farther away from the heart, and the ribs are separated, so the natural image is relatively poor.

Inserting instruments from the apex of the heart, whether for the ventricular septum or the left ventricle, there are almost no dead spaces in the operation, and "freedom of view" and "freedom of operation" are very important for surgical procedures.

The electric rotary cutter is already in place and starting to start, and it can be operated with a handle, just like the power planing instrument used in arthroscopic surgery, which is very convenient.

The hypertrophic ventricular septum was adsorbed by the cutter head, and the rotary cutting blade cut it, Professor Cao, Director Xin, and Director Xiang, who were engaged in cardiac surgery, were focused on watching the operation, and they were watching the famous hall, while many other students were around, and they were watching ten pigs, and they were watching the excitement.

It is very important to leave no bubbles and debris when cutting, the cardiovascular system is a closed duct system, and the debris or a large number of bubbles produced in the heart will become a wandering emboli, which will enter the aorta from the left ventricle with blood circulation, and then enter the systemic circulation, that is, the large circulation.

The arterial vessels are thinner and thinner, and finally the capillaries are connected, and then the veins are connected.

The embolus travels along with the blood flow, and there is always a place where the arterial blood vessel will be smaller than the diameter of the emboli, and at this time, the embolus will block the blood vessel, causing ischemia in the area where the blood is supplied, and these places will lose the irrigation of the blood and will soon infarct.

If it is a vital organ that is blocked, it is very dangerous, such as an acute cerebral infarction.

Everyone was concentrating on the operation, and they didn't notice that the hospital leaders were wandering around the operating room, and no one went to say hello.

Even if someone sees it, they pretend not to see it, for fear that the greeting will affect the progress of the operation.

Dean Xia, Director Han and Director Zhao watched the operation together and whispered to Huang Jiahui about the knowledge of the new instruments.

Then stop and watch for a while, just like everyone else.

Their arrival is to convey a supportive attitude to Yang Ping, as for what the operation does, they don't care at all, anyway, just let Yang Ping make trouble, whether you play pig or cow.

After a long time in the operating room, the leaders went to see the experimental pigs, asked the seller protection team about some details about the experimental pigs, and tried to catch a pig in the Baoding circle to play.

"You pig barks, don't you?" Dean Xia asked the breeder.

The keeper smiled and said, "How can a pig not bark." ”

"I mean, will your pig scream so loudly that everyone around him can hear it, and affect the rest of the people nearby."

The keeper pondered for a moment and said, "Generally, no, but it is inevitable, after all, it is a pig, and people sometimes get angry and lose their temper." And in this way, pigs are strictly captive since childhood, and then raised to do experiments, some pigs will be in a bad mood, depressed, in order to express dissatisfaction with life, will also scream a few times. ”

After hearing this, Dean Xia thought that if this place was to be transformed into a surgical laboratory, he would often pull some experimental pigs over in the future, so the renovation and decoration of the laboratory was very important.

"In the future, we will have to pay some attention to the decoration and sound insulation of the surgical laboratory, if these pigs bark, it will interfere with the patient's rest."

Dean Xia gave a little advice.

Director Han feels that there must be special people for environmental disinfection here, and pigs are animals with certain particularities.

"Although the pig does not stay for a long time in the future, it is also a mixture of humans and animals, and the environmental disinfection treatment has particularities.

"Yes, we have a set of methods and systems to ensure strict hygiene in laboratories with animal participation." The experimenter replied immediately.

He saw that these were leaders, so he took the opportunity to sell them, hoping to get business.

Director Zhao followed: "Compared with ordinary pigs, these experimental pigs have stricter requirements in terms of epidemic prevention, and they are very careful when they are raised. ”

"It's illegal to slaughter without permission, we can recycle it, you can hand it over to us." The veterinarian replied.

Several leaders of the institute stood at the door of the room where the experimental pigs were closed, and started a serious discussion around the pig problem.

——

The operation is still going on here, looking at the image on the color ultrasound monitoring screen, Director Xin touched his chin, this operation is really interesting.

Regardless of what happens after surgery, at least now the ventricular septum is being thinned, and this incision method is not only effective, but also excision is precise, and the surgical method is minimally invasive.

What puzzled Director Xin was why Yang Ping's operation was so skillful, not at all like the new techniques and instruments he used for the first time.

According to common sense, the new surgery that is done for the first time must be done carefully, slowly, step by step, but this is not the case with Yang Ping at all, and his operation is very skillful.

Director Xin got closer and glanced at the electric knife rotary cutter in Yang Ping's hand, how could this be a recent innovative product, this mature device from the germination of ideas, to the drawing of drawings, to many trial production, improvement, it is important to be able to get a mature product for three or four years.

This new surgery is certainly the result of several years of hard work, not a short-term result, Director Xin concluded.

It is much more convenient to enter the left ventricle from the apex of the heart to remove the hypertrophic interventricular septum than from the aorta, one is a roundabout side attack, the other is a frontal attack, if it is a war, the former will achieve a surprise effect, but it is another thing to do surgery, a frontal attack is more straightforward than a roundabout side attack.

Directly, there is more freedom in vision and space, and "freedom of vision" and "freedom of operation" are the basis of surgery.

It's a good way, the more Director Xin thinks about it, the more wonderful it is, but I don't know what the situation will be after the operation, and whether it will cause embolism due to debris.

After cutting almost 20G of myocardial tissue, Yang Ping stopped the operation and said:

"Cutting too much can cause block, but today is an experiment, in order to show the effect of the rotary cutter, I still cut a little more, and if there is a block, we will install a pacemaker." Yang Ping gave the audience a vaccination in advance, especially the two professors Cao Zhenshan and Xin Weicong.

Because it was the first operation, Yang Ping needed to show the great power of the electric rotary knife, so he cut out a full 50G myocardium from the ventricular septum and left ventricle before stopping, and the usual operation did not need to cut so much myocardial tissue at all, and the heart of the experimental pig was normal, not hypertrophied, so after removing so much myocardium, the No. 1 pig really had conduction block.

In order to obtain more experimental data, Yang Ping did not give up the experimental pig and installed a permanent pacemaker on the pig to maintain the normal beating of the pig's heart.

The first operation was completed, according to the normal surgical process, Yang Ping sutured the small puncture opening at the apex of the heart, and then sutured a small 5 cm incision in the chest, and the No. 1 pig left the operating room with the ventilator and entered the temporary observation room.

Pig No. 2 has been anesthetized by the seller's team and moved to the operating table.

Some people have begun to talk to Huang Jiahui in the audience to understand the structure, principle and operation method of the instrument, and Director Xin also noted down this little girl, and after watching the operation, he also wanted to see this rotary knife.

Professor Xin moved a little closer to the operating table, and he asked the instrument nurse to show him the cut out myocardium, wanting to see what the cut myocardium looked like.

Zhou Can gently clamped the myocardium with vascular clamps and lifted it up to Professor Xin to see.

This piece of myocardium is whole and slightly curled, and if the blade is sharp enough, this way theoretically does not produce chips.

Professor Xin has always been worried about the interference of metal instruments with color ultrasound in the esophagus, and now it seems that there is no problem, and the color ultrasound images have no artifacts caused by metal, which is very clear.

The operation is very fast, because of the improvement of the surgical method and the innovation of tools, the operation has become relatively simple, compared with thoracotomy surgery, as long as the heart muscle is not cut too thin or cut through, there is basically no problem.

Later, it is getting faster and faster, and the support team makes a preparation room in another room, anesthetizes the pigs in advance, and the operation here is over, and the pigs over there are sent over immediately, so that it is almost an assembly line operation, about five hours, and the operation is over.

By the end of the day, Professor Xin had forgotten his identity as an "observer", what else was he was observing for this kind of surgery, and what he was thinking about now was how to get a rotary cutter back, and he would try it himself.

"How?"

Professor Cao asked Director Xin beside him, but he turned his head to find that his student had disappeared, and when he looked again, Director Xin was already asking Yang Ping for a rotary knife, saying that he also wanted to try this operation.

It seems that Sanbo Hospital can prescribe comprehensive surgery for him, this young man's ability is really great, and not everyone has this strength in 13 CNS.

13 articles, don't talk about Jieqing, you will have to be promoted to academician soon, I really don't understand, why are young people so powerful now.

"How?"

Professor Zhang Zongshun asked Professor Cao.

Professor Cao pestered Huang Jiahui at this time and listened to Jiahui's introduction to the principle and use of the instrument.

The principle is very simple, similar to cutting a pineapple core, but it takes a lot of effort to make a precision power device with such a simple principle.

Let's go to see the pigs after surgery, the drug dose control guided by Liang Fatzi is very good, and three pigs have been removed from the tracheal intubation, walking around in the temporary pigsty, as if nothing happened.

——

Experiments are still being done on pigs here, and Xinmei's surgery will naturally have to wait.

But you can't always tell patients and their families: you wait, our new technology will operate on the pig first, and if the pig is alive and well, then it will be brought to you to do it.

Therefore, in order to avoid some misunderstandings, Li Guodong did not tell Teng Xinmei and his father about the pig experiment for the time being.

Teng Shaokui was anxious, the little girl in the next bed who was admitted to the hospital the day after her daughter had already completed the operation, and Xinmei's surgery had not yet been done.

Hey-——, money is not in place, how can it be possible to arrange surgery.

Fools understand the truth, who will pay for the money if they run away after the operation?

At this time, Teng Shaokui was already very anxious and anxious, fortunately, he finally heard Boss Li's latest call, and he found an opportunity to sneak out and call Boss Li's phone.

After ringing a few times, the other party answered the phone, and the voice was still really Boss Li.

"Boss Li - I'm Da Kui, Da Kui!"

The other party probably didn't expect Teng Shaokui to call him, and thought for a long time before saying, "Oh, Da Kui, where are you now?" ”

"I'm not staying in my hometown, what about you, you're still building a highway in Guizhou?"

"No, I'm in the provincial capital now, and I've been here for more than a year."

"Provincial capital?"

Actually in the same city, Teng Shaokui rekindled his hope, and his heart was very excited.

"I—I'm in the provincial capital now." Teng Shaokui said excitedly.

"You're there too? Where is it? ”

"Sanbo Hospital!"

"Sanbo Hospital? I don't think there's any work over there. ”

"It's hard to put into words!"

"I'm busy now, I'll go to Sanbo Hospital to find you in the afternoon, wait for my call, you, big brother, are also in the provincial capital." The other party laughed a few times and then hung up.

Teng Shaokui didn't dare to mention borrowing money for the time being, he hadn't seen him for many years, and he opened his mouth to borrow money, for fear of scaring others.

Although he had been thinking about borrowing money from Boss Li before, and it took so much effort to finally contact Boss Li, Teng Shaokui hesitated in his heart, and it was very difficult to borrow money.

But if you don't open your mouth, who will you turn to?

Relatives asked a lot, and they could raise up to 20,000 yuan, which was still the amount promised verbally.

Needless to say, after opening up the matter, Zeng Cuiling scolded directly.

Zeng Cuiling scolded Teng Shaokui for lacking heart and eyes, is it water in his head, spending 100,000 yuan to have surgery, Xinmei is not good now, she will soon graduate from junior high school and go out to work, she should let Xinmei earn money for treatment in the future, or let her future husband or in-law pay for it.

Teng Shaokui had no choice but to turn off the phone, he was now alone.

PS: The prototype of the new operation in this case is Professor Wei Xiang, director of the Department of Cardiac Surgery of Tongji Hospital Affiliated to Huazhong University of Science and Technology, who performed transapical myocardial atherectomy. Hats off to Professor Wei Xiang!
