godfather of surgery

Chapter 1203 looks like a mentally challenged person.

Actually, using this company's products was just a coincidence. There are only a handful of companies in the country that make artificial hearts. Looking at the product parameters, it met Professor Yang's recommended requirements: small size, long battery life, and priority given to domestic products. There was only one company like this, and their battery waterproofing is also excellent.

So Director Tian called this supplier. If that didn't work, he would call other suppliers. The hospital's supplier list only had these few companies, and there were only these few companies nationwide.

Unexpectedly, this chance encounter changed the company's fate. Less than an hour later, during a chat, they finalized an investment of one billion yuan.

Moreover, the other party doesn't care about short-term profits; they only care about whether they can make a good product.

Even after slapping himself, President He still felt like he was in a dream. Not long ago, he was constantly meeting with investors, his voice was hoarse every day, he hadn't raised a single penny, and he had been ridiculed a lot. Today, he had already secured a billion-dollar investment. Anyone would find it hard to stay calm in this situation.

"What did General Manager Huang just say about where to sign the contract?" General Manager He asked one of the vice presidents who was traveling with him.

The vice president said, "General Manager Huang said to let us consider it. If there are no problems, we can sign the contract immediately. We will decide the time and place for the signing."

"What are you still considering? Let's sign the contract directly. Invite General Manager Huang to visit our company and give him confidence. Let them see that we are truly technically capable, not just some team that uses PPTs to fool people. After the visit, we can sign the contract. What do you think?" General Manager He finally came to his senses.

The vice president said, "We'll do as you say."

President He touched his burning face: "Why do I keep feeling like this is unreal? You said he just mentioned 1 billion, right? I'm afraid he's gone crazy trying to attract investment every day."

"I think so too, but he really said that just now," the vice president confirmed, because he had also secretly pinched himself a few times, and it hurt a lot.

President He went into the bathroom and washed his face with cold water.

clap clap clap!
A loud slapping sound came from inside, startling the colleagues outside. They wondered if the man had really lost his mind.
-
An Chenfeng's surgery is being prepared. No contraindications were found during the preoperative examination, so the surgery is scheduled for the next day.

The progress of modern medicine is actually the progress of physics, chemistry and biology. For example, the artificial heart was made possible entirely by the progress of electronic technology and biomaterials in physics. The same is true for various minimally invasive surgeries and robotic surgeries, which were brought about by the development of physical technologies such as sound, light, and electromagnetics.

Artificial hearts mimic the heart's pumping action, but the biggest problem is that the pumping process can cause mechanical damage to red blood cells. This damage can lead to thrombus formation and ultimately embolic diseases.

Magnetic levitation artificial hearts use magnetic levitation technology to replace the previous mechanical technology, which greatly reduces mechanical damage, but it does not mean that mechanical damage does not exist.

Theoretically speaking, the simulation gap is an inherent technical defect of artificial hearts. These defects can be reduced with technological advancements. Therefore, with the development of artificial heart technology, postoperative survival time will definitely increase, and at that time, allogeneic heart transplantation will no longer be necessary, and end-stage heart disease can be treated with artificial hearts.

In the future, implantable artificial lungs, artificial livers, and artificial kidneys will also appear; it's just a matter of time, and they will definitely develop with the advancement of technology.

Of course, if Yang Ping eventually masters the laboratory cloning of all organs, then artificial organs will not be very useful. This is because as long as an organ fails, this laboratory cloning technology can be used to replicate the organ and then transplant it. The result will be exactly the same as the original organ in its healthy state, and there will be no rejection reaction from foreign organs, nor will there be any simulation gap between artificial organs and natural human organs. No matter how advanced artificial organs are, they will always be different from natural human organs.

The parallel research on artificial organs and cloned organs will continue for a long time. This is the future approach for end-stage organ failure. Allogeneic transplantation is only a stopgap measure for a period when the technology is not mature, and it is certainly not the ultimate solution.

Yang Ping shared his thoughts on the treatment of some end-stage diseases. His stem cell laboratory will focus on researching organ cloning technology. Currently, cloning skin and muscle is just the beginning. In the future, he hopes to complete the cloning of all organs under the guidance of the space-guided gene theory. This process will be very long, but it is definitely achievable.

Space-guided genes are like an invisible 3D printer, using various cells to build complete organs. What we need to do now is to find the on and off factors of space-guided genes for each organ, so that each organ can be cloned in the laboratory in the future.

Now that An Chenfeng's treatment plan has been finalized, the surgery has been scheduled, and the artificial heart from Xinbao Company has been delivered to the operating room.

Mr. He personally served as the engineer accompanying him. It's 10 billion yuan, and there will be further investments. With this money, Mr. He is fully confident that he can make Xinbao a world-class artificial heart manufacturer. Mr. He is a little dizzy now. He slapped himself again when he woke up this morning, afraid that he would wake up from the dream.

Early in the morning, President He waited outside the operating room. Actually, there was no need to arrive so early; it wouldn't have mattered anyway. President He's main purpose was to show his attitude.

For safety's sake, he brought along the company's best on-site engineer, just in case. Although he was very familiar with the technology of his own products, he was still relatively unfamiliar with the on-site process.

The research institute requires that the surgeon, scrub nurse, and assistants be extremely familiar with the products, and that the on-site engineer is not allowed to be on the operating table. Therefore, the on-site engineer can only assist from the sidelines, handling technical crises such as the need to replace the artificial heart if it becomes contaminated. Of course, this is almost impossible, but surgery requires meticulous planning and multiple backup plans. Ideally, these should not be used, as the lack of a comprehensive backup plan would be extremely problematic should an unexpected situation arise.

Although Yang Ping did not go on stage, he would be sitting in the audience. It's not that Xia Shu couldn't perform the surgery or that the surgery was difficult, but rather that Yang Ping was there to support the product. His presence in the operating room makes a huge difference compared to his absence. When he is in the operating room, people will say that Professor Yang and his team performed the Heartbao 3.0 artificial heart replacement surgery, which carries a significantly different weight.

Upon seeing Professor Yang in the operating room, President He understood that this immense wealth was no longer just a matter of a billion-dollar investment. His artificial heart was about to take off; this was the so-called culmination of years of hard work. In terms of technology, President He didn't think he would lose to anyone, so once the winds of change picked up, Xinbao Company would definitely be able to take off.

"Professor Yang!" President He always appeared very humble, bowing deeply, which made Yang Ping feel a little uncomfortable. Only Takahashi had ever done that before.

“President He!” Yang Ping responded to him.

Seeing him bow, Yang Ping was reminded of Takahashi. Sometimes Takahashi bowed even more deeply than him, which made Yang Ping wonder: Is the incidence of lumbar disc herniation higher in Japanese people than in Chinese people?

President He immediately said, "Just call me Xiao He."

Actually, President He should be a year or two older than Yang Ping, and he looks significantly older than Yang Ping. Calling him "Little He" seems a bit strange, or so President He himself thinks.

Actually, Mr. He didn't have much to do in the operating room. The doctors and nurses here were very familiar with his artificial heart, unlike some hospitals where doctors are sometimes unfamiliar with the product and need to ask the on-site engineer about various parameters during the operation, or simply complete the operation with the help of the on-site engineer.

For example, in artificial joint replacement surgery, the attending surgeon often needs to be on the operating table to help assemble the artificial joint and various supporting instruments. Strictly speaking, this is not allowed. If the doctor and scrub nurse are not proficient in assembling the artificial joint and supporting instruments, and they are allowed to perform the surgery, the entire operation will have many potential risks.

This kind of situation is clearly not allowed at Sanbo Hospital. If any surgeon did this, they would be laughed at. So even for new products, surgeons will thoroughly study them in advance and be very familiar with the product's principles, structure, and various parameters.

In fact, regardless of the type of medical device, similar products are generally very similar, with little difference in the main technologies and only some differences in details.

The surgical team must be very familiar with all the surgical instruments and implants used in the operation. This is a basic requirement, but it is sometimes difficult to meet this basic requirement.

The patient, An Chenfeng, was already lying on the operating table. The anesthesiologist was Dr. Wei, who worked silently throughout the entire process, keeping his head down. At times, one might wonder if he had lost his ability to speak.

"The anesthesia has been successfully administered!"

Finally, Dr. Wei uttered a sentence, one of the few sentences he uttered each day in the operating room.

Xia Shu went out to wash his hands with his assistant, while Yang Ping stood in front of the X-ray light to study the patient's CT images. In fact, he had studied these CT images many times, but he had nothing to do in the operating room. The surgery had not yet started, and he could not chat idly, so he did not mind analyzing them again.

President He was also standing beside him. Although he couldn't understand the CT images, he pretended to look at them with Yang Ping. He wanted to thank Yang Ping, but then he thought that such a big deal as a billion-dollar investment would be too trivial to just say thank you. So he didn't know what to do for the time being and couldn't find a way to thank Yang Ping. He could only try to be polite and humble in front of Yang Ping, which might make him feel a little better.

Yang Ping turned his head and felt someone next to him. He saw it was President He. Actually, he was standing too close, and the hot breath he was exhaling from his nostrils was a bit too heavy.

Upon realizing the problem, General Manager He immediately moved aside and gave an awkward smile.

"From a doctor's perspective, the most important parameters that need improvement for artificial hearts are: minimizing damage to red blood cells from the device itself to reduce the possibility of thrombosis; low energy consumption and long battery life; adequate waterproofing, as poor waterproofing would greatly inconvenience patients; and low weight and size, which you've done very well so far. Another crucial point is the excellent integration of this product with human tissue. This is a weakness of all artificial hearts; if it's to replace the heart in the future, the interface with major blood vessels must allow for a biocompatible anastomosis, something that current artificial hearts cannot achieve," Yang Ping told General Manager He.

Mr. He immediately took it to heart. Every word he heard was advice from a world-class doctor for the product. This was the best customer advice, and it had immense value.

He didn't bring a notebook or pen, so he asked the anesthesiologist for a pen and a piece of paper and wrote it down on the spot.

"You don't need to be so serious. I was just offering a suggestion casually. It might not be right, but I'm just seeing if it can help you," Yang Ping said with a smile.

But Dr. Wei took the paper and pen and started writing furiously.

After disinfection and draping began, Xia Shu led the doctor onto the operating table. The surgery was not difficult; Xia Shu was now very skilled in cardiac surgery. In fact, as long as young people have solid theoretical knowledge, someone to guide them through hands-on practice, and they are willing to learn, their surgical skills will improve very quickly.

Surgery is primarily a skill that requires manual dexterity, and the younger you are, the easier it is to learn.

Yang Ping remembers clearly that some chief physicians who studied percutaneous endoscopic discectomy for a long time just couldn't learn it. As they got older, their ability to learn new things was still a bit weaker.

Xia Shu's movements were incredibly swift and efficient, a far cry from his time at Fuwai Hospital. He had only been here a short time, yet he had already mastered the vast majority of heart surgeries.

Xia Shu didn't need the help of the Taiwanese engineer at all; he didn't ask President He or the engineer a single question throughout the entire process.

The laser pointers that General Manager He and the engineers brought were never turned on even once.

There are many types of artificial hearts, including temporary artificial hearts such as ventricular assist devices. These are used for short-term temporary support to help patients transition to heart transplantation or recovery of heart function. Their role is temporary, short-term, and transitional.

There is also a fully artificial heart, which can completely replace a natural heart. This is what An Chenfeng is currently working on, and it will replace the heart in the body and function for a long time.

All artificial hearts operate on similar principles, typically consisting of a mechanical pump, a chamber made of biomaterials, and an external control system. Driven by electricity, they pump blood by simulating the rhythm of the heart's contraction and relaxation. Ultimately, it is a pump.

Compared to natural hearts, artificial hearts have many disadvantages. For example, they have poor physiological compatibility; a natural heart can dynamically adjust the amount of blood pumped according to the body's needs, while an artificial heart relies on a pre-programmed procedure or external control. They also have poor durability; mechanical parts may malfunction due to long-term wear and tear, requiring regular maintenance or replacement. Patients' psychological acceptance is also relatively lower; after all, carrying a small machine inside their body that sustains their life can be psychologically difficult to accept, and some patients may require post-operative psychological counseling.

The gap between artificial hearts and natural hearts means that artificial hearts are destined to be a transitional stage, and the future end-stage treatment of organs will definitely be autologous cloned organ transplantation.

Yang Ping and President He chatted while watching the surgery. President He agreed, but said that this transition would be a long time, so the artificial heart would exist for a long time.

Xia Shu quickly completed the surgery.

While ensuring surgical quality, the faster the surgery, the better, as this reduces the exposure time of the surgical field to the air and decreases the risk of infection.

Is the surgery over?
Mr. He didn't quite realize what was happening; it wasn't like this at other hospitals.

"Is it finished?" General Manager He asked the engineer.

At this point, the surgeon began to remove his gloves, but he didn't remove them until the procedure was finished.

The engineer was a little puzzled. Why did General Manager He seem like a mentally challenged person at Sanbo Hospital? His behavior was strange. He could just greet people, but he had to bow so much, making himself look like a Japanese person.
