Here the focus is on polyamide wrinkled yarn.

At the beginning, Chen Qi and they used gauze wet with normal saline in Africa, which was no way, it was really the same as Tubalu.

Because the elasticity of gauze is not very good, it often cannot be expanded to 9 times, and it is difficult to even expand to 5 times.

So later, Chen Qi and the others had to carefully clamp the tiny skin, which was only 2.8 mm in diameter, with a camera, and then put it evenly on the gauze.

After an operation, the eyes and old waist are really sinful, they are about to be wasted, and it takes longer, which increases the risk of surgery.

After returning to China, Chen Qi began to look for suitable materials based on the memories of his previous life.

Coincidentally, Yuezhong is the largest textile producing area in the country, and the Textile City located in Keqiao Town is the largest fabric wholesale market in the country.

So Chen Qi went to the Textile City when he was free, looking for the fabrics he needed everywhere.

He is a celebrity in Vietnam and a major shareholder of the Textile City, and every time he asks for a small piece of fabric, the cloth seller will happily cut it out with scissors and give it away.

After all, some fabrics and patterns are exclusive, and cutting off others may be to prevent theft.

In the end, Chen Qi found two raw materials, "polyamide" and "crepe", and then found a teacher from the textile department of Yuezhong University to spin "cloth" into pieces by hand.

Polyamide is made of nylon, and crepe is made of silk, and the combination of the two has very good fabric tension, and it can be expanded to the extent that Chen Qi is satisfied, which is perfect.

Only then did the "stinky tofu skin grafting" break a technical bottleneck and proceed smoothly.

When the wrinkled yarn was stuck to the tiny skin, Zhu Huoyan and Chen Qi each pulled a corner with their hands and pulled them evenly in all four directions.

As the polyamide crepe de chine expands, the tiny skin particles are evenly and neatly separated, looking like stars with a regular distribution.

When several professors outside saw this step, they already understood Chen Qi's surgical principles, and they all started to discuss.

In fact, the principle is similar to stamp skin grafting, but the technical difficulty of stamp skin grafting is low, and the skin is the same size as a stamp, and it is very simple to place it on the burn wound.

The "stinky tofu skin grafting" is more demanding because the normal autologous skin is smaller, so small that you can't see clearly without reading glasses.

This is suitable for those burn patients who have a huge burn area and a scarcity of their own normal skin, and the advantages are even more obvious.

The professors who could see the outside nodded frequently, commenting a few words from time to time.

Originally, at this point, the Vietnamese-Chinese team only needed to cover the wound with the expanded polyamide crepe on the wound, and the operation would be completed.

But Chen Qi found another inspiration from Dongshan Hospital.

Originally, in the 90s, Dongshan Hospital would invent a new skin grafting procedure, called "large allogeneic skin hole autologous small skin piece embedded skin grafting".

The principle of this surgery is to first find a relatively large piece of allogeneic skin, make N small holes in the large allogeneic skin, and then embed a microsheet of the patient's own skin into the hole, and then transplant the large skin to cover the burn.

While the allogeneic skin is gradually rejected, small autologous skin patches continue to grow until they gradually cover the entire wound.

This principle is actually the same as stinky tofu skin grafting, or most skin grafts.

The advantage of "large allogeneic skin hole autologous small skin piece embedding skin graft" is that it can effectively solve the problem of insufficient autologous skin source, and at the same time can protect the entire wound from exposure.

But there is also a disadvantage, that is, the whole allogeneic skin is required, which is very costly, because you need to think of special ways to get it, such as ...... Uh-huh...... On the banks of the Ruoye Creek......

Moreover, the embedding process of the leather sheet is more complex and the operation time is longer.

Chen Qi found inspiration for the skin implant invented by Dongshan Hospital.

Since it is very troublesome to make small holes in the allogeneic skin and fill them one by one with the patient's own skin, Chen Qi can add another step on the basis of "stinky tofu skin grafting".

That is, MEEK skin grafting is done first, and then the entire allogeneic skin is covered on the wound, so that the innermost layer of one's own skin can quickly merge with the wound, so as not to fail the skin graft surgery due to infection.

This is equivalent to the combination of "meek skin grafting + large allogeneic skin piercing autologous small skin piece embedded skin grafting", double insurance treatment, can the effect be poor?

It was the poor Dongshan Hospital's later ace skin grafting that was cut off by Chen Qi.

In order to disgust Professor Ni Zhihua and Dongshan Hospital, in today's operation, Chen Qi also drilled several holes in the allogeneic skin, and then embedded the leftover skin cut off by the patient into the middle of the allogeneic skin, and then covered the patient's wound.

As for the huge "allogeneous skins" prepared by Chen Qi, where did they come from?

Don't ask, if you ask, it's picked up by the bank of Ruoye Creek......

Now the doctors of the Vietnamese Central Hospital are doing this operation in front of several of the most authoritative burn experts in China, and Chen Qi is not afraid of defaulting on the debts or plagiarism in Dongshan Hospital in the future.

If they dare to copy, Chen Qi will dare to broadcast to them all over the world.

Professor Ni sat outside the operating room, not knowing that his luck had been unknowingly siphoned off and his beard had been amputated.

Professor Ni, who was unaware, looked at his watch and was still very surprised:

"Well, the Viet Cong Hospital really only used 10% of the normal skin, covering 80% of the burn wounds, and the whole operation only took one and a half hours."

(Some unimportant areas are not covered)

Professor Peng was also reviewing the operation just now in his mind, and at this time he also patted the armrest excitedly:

"Well, this operation solves two major problems, one is that it is difficult to support and cover the whole body skin graft with large-scale burns, and the other is that stinky tofu skin grafting is simple and easy, and the technical requirements are not high, which is very suitable for promotion, and the Vietnamese Chinese Hospital is too powerful."

Professor Wang Qizheng was a little worried, originally the best burn department in Haidong Province was the Second Hospital of Haidong Hospital, but now it seems that he can't beat the Vietnamese Central Hospital, should he go to Yuezhong to work in advance?

Professor Ni Zhihua is cautiously optimistic:

"Don't worry, there are still 3 patients who need to be transplanted, to see if the operation can be successful, and to see if the transplanted skin can survive, these are all problems."

Professor Zhu Lianggong and Professor An Yongchun did not express their opinions, touching their chin with their hands and still thinking about the previous surgery.

Professor Peng Yongyan suddenly said:

"You say, how about we arrange the annual meeting of the National Burn Injury to be held in Viet Cong? There are not many opportunities for 4 patients with large-scale burns at the same time, so that counterparts from all over the country come to visit and learn. ”

Professor Wang Qizheng must help his own people at a critical moment, so he quickly nodded:

"Yes, Professor Peng's method is good, leaders like to work on-site to solve problems, and our burn society must also learn to teach on site, if these 4 surgeries in Vietnam-Central Hospital are successful, then they have created a world first."

Professor Ni Zhihua was obviously not happy, because the National Burn Annual Conference was held in Shanghai, and Dongshan Hospital was the host, and he also wanted to brag about showing the achievements of Dongshan Hospital with his counterparts across the country.

"That's not good, Huhai has set up a guest house."

As a result, Professor Zhu Lianggong, who had not spoken before, spoke:

"I also agree with the opening of the National Burn Annual Conference in Vietnam, such a good opportunity is in front of us, if the formula and experience of Vietnam and China are successful, and can be successfully promoted throughout the country, then our Chinese burn surgery can dominate the world."

Professor An Yongchun also raised his hand in agreement.

Four of the five Standing Committee members agreed, and it was useless for Professor Ni to oppose it alone.

Fortunately, this year's medical annual meeting was not as grand as in later generations, and there was no sponsorship from pharmaceutical companies in this year, so everyone went out to meet in order to save money, and lived in a guest house, and the meeting venue was often selected in the conference room of the local hospital.

Huhai is not far from Vietnam, and it is not difficult to take a few hours by train, and it is not difficult for the participants to temporarily transfer to Vietnam.

In the 80s, burn surgery was actually an unpopular discipline, and it was a "primary school meeting" like the cleft lip and palate society that Chen Qi first played, or the plastic surgery society.

Why? Because there are fewer patients.

Think about the 80s, when the common people had just eaten enough, and a few years earlier, they couldn't even eat enough.

When someone encounters scalds and burns, the first thought that comes to mind is to apply soy sauce or dog oil at home, and then get some Chinese herbs, and almost no one is sent to the hospital.

There are burn surgery patients in big cities, and the source of the disease is generally from the work-related injury, the reimbursement of the factory.

Otherwise, the cost of large-scale burns like the three workers of the Vietnamese Iron and Steel Plant is tens of thousands, and tens of thousands of yuan can be spent to treat burns in the 80s? Is it possible?

In addition, the main patients in burn surgery are mainly troops, and the state still attaches great importance to its own soldiers.

Whether it is the Chongqing formula or the Nanjing formula, it is actually developed by the military hospital, accounting for two-thirds of the mainstream formula.

Therefore, when it comes to the annual meeting of the National Society of Burn Surgery, there are not many doctors attending the meeting, and only 50 doctors come from all over the country.

There are few doctors, which means that the organization of the meeting is simple, and the boat is easy to turn around.

When Professor Peng told Guo Yuanhang Shuji about this proposal, Comrade Guo was excited:

"Okay, no problem, the National Burn Annual Conference will be held in Vietnam, and our Yuezhong Hospital has sponsored the whole process, we have included accommodation, and our hospital also has a ready-made conference room to ensure that the meeting goes smoothly."

The Vietnamese and Chinese hospitals have money, and Lao Guo has the confidence to speak.

Chen Qi was also happy when he heard it, and he couldn't imagine that he originally wanted to help the project of Yuezhong Hospital to generate income, but he actually caught a big fish.

If the National Burn Conference is held at the Viet Chung Hospital, which is a free advertisement, the popularity of the Burn Surgery Department of the Viet Cong Hospital will be quickly opened and known by more people.

If the Vietnamese Central Hospital can become a key hospital for large-scale burns in the country, there will be no shortage of patients at that time, which will be another big income generator.

The burn department is not the same as endoscopic surgery, the cost of endoscopic surgery is really not high, and a few hundred yuan is charged for a surgery.

But burn surgery is different, a system of rescue, the equipment and drugs used are sky-high.

Generations of blood products, bottles of imported medicines, plus repeated surgeries, a burn patient and so on to be discharged from the hospital, without tens of thousands of yuan, simply can't get down.

For example, the medical expenses of these workers in the Vietnam Iron and Steel Mill, so far, the Vietnamese Steel Mill has paid more than 50,000 yuan, and the follow-up treatment will require a large sum.

Of course, the Vietnamese steel mill said that it was to save 3 patients, in fact, they paid for 5 patients, ahem, so it was a little more......

It's no wonder that hospitals like to develop surgery, and it's no wonder that surgery is easy to produce results and leaders, because surgery is so profitable.

Lao Guo saw that Chen Qi agreed, so he proposed:

"Next, Song Yanzi and Wang Chuanbing's surgery will be delayed, and after the foreign burn doctors have arrived in Yuezhong, let's have a live teaching operation. In addition, Lu Wenjie's condition is more complicated, and necrotic tissue needs to be removed, and you will wait until the day after tomorrow to do it. ”

"Okay, then delay it for two days, and then we will show our hands."

The hospital office and medical department of the Vietnam Central Hospital also immediately took action, contacted the guest house, and arranged the meeting venue.

The Vietnamese Central Hospital has organized several meetings of foreign experts, so organizing a national burn conference is a trivial matter.

In 1989, the annual meeting of the National Society for Burn Surgery was temporarily held at the Viet Chung Hospital.

This move surprised many of the participating doctors who had already gone to Shanghai, and they were all confused.

The temporary change of meeting place is a bit offensive, because in these days it is not only meetings, but many people take the opportunity of meetings to travel, or even travel with their families.

Greater Shanghai is the most popular tourist destination in the country, and people these days want to go to the Bund and buy a few woolen sweaters and White Rabbit toffee on Nanjing Road.

The meeting was held in Vietnam, and although it is also a historic city, it is a standard rural area compared to Shanghai.

As a result, many people expressed their dissatisfaction:

"Why go to Vietnam? I won't go without giving a reason! ”

"Yes, yes, how can there be a temporary change of address, such a big Huhai, is there no place for a meeting?"

"I can say well, my time is precious, how many patients are waiting, but I don't have time to fool around with you!"

The doctors who attended the meeting were all gossiping and talking, and the atmosphere began to become unfriendly.

Those who can participate in the national conference are all directors of major hospitals, and even directors and the like, and this group of people is not easy to fool and has a big temper.

This made the staff of the organizing committee (mainly the Vietnamese Central Hospital) anxious, on the contrary, Guo Yuanhang, who personally went to Shanghai to pick up people, was not in a hurry at all.

"Professors, teachers, everyone be quiet, listen to me, I am the secretary of the Yuezhong People's Hospital, and I want to explain to you why the National Burn Annual Conference was temporarily changed to our Yuezhong recruitment."

Everyone is a quality person in the end, and when they heard someone explain, they all fell silent.

"Everyone is an expert in the field of burns, and everyone should know that patients with large and severe burns, more than 60% of the burn area, there is no record of successful rescue, both at home and abroad, right?"

The people below didn't know why, so they didn't say anything, wanting to hear what this Shuji from the Viethorne Hospital wanted to say.
