The operation is about to begin.

The nurse has prepared alcohol lamps, fire needles and other related props.

They have long been accustomed to these operations these days.

However, the people outside the assessment and observation room were a little uncomfortable with it.

After all, surgery has always been combined with modern scientific and technological products. Surgery like Chen Nan's, which combines traditional Chinese medicine surgery with modern medicine, is really rare.

Although Chen Man has also seen this surgery of fire acupuncture combined with superficial veins, to be honest, after seeing these acupuncture instruments and alcohol lamps with his own eyes, he still felt very strange.

Not only her, but also everyone who came to visit and study.

These people are basically all from Western medicine backgrounds and have certain attainments in the field of surgery. After they suddenly saw the fire needle, the impact on their hearts was still very strong.

"Is this really a serious operation?"

I don't know who in the crowd suddenly said such a sentence, and everyone burst into laughter.

If it weren't for the fact that fire acupuncture combined with percutaneous superficial vein surgery has really attracted a lot of people recently, and their efficacy and recovery time really save a lot of time compared with traditional surgery, reduce the surgical opening, and reduce the patient's medical expenses, they would also

I really look down on it.

This kind of disdain is deep-rooted.

This is not to say that there is targeted discrimination against Chinese medicine, but that Western medicine surgery has always represented advanced, leading, and technological sense.

Traditional Chinese medicine represents a magical "earth flavor".

Changes in Western medicine are often accompanied by innovations in medical equipment, such as generations of pulse instruments, laser treatments, etc. The introduction of these technologies into the medical field has had a special impact.

Chen Nan's improvement seems to be a bit "returning to nature".

Ruan Yongyi smiled: "Why does surgery have so many fancy things? Being able to successfully treat diseases and better help patients is the ultimate starting point."

Chen Man nodded, she agreed with Ruan Yongyi's point of view.

Here, the operation is about to begin.

Listening to everyone's discussion, Wang Lun hesitated for a while, then collected the situation here and sent it to Lu Xianping.

…

The operation begins.

Chen Nan held the fire needle and directly started pricking and bloodletting therapy.

When the blood in the varicose veins was released, Chang Ruyi quickly began to wipe it, but did not do anything to stop the bleeding, but waited for the blood to continue to be released.

Bloodletting therapy is actually relatively easy to accept at home and abroad. After all, in the West, bloodletting therapy was their traditional craft.

However, fortunately, after combining their traditional craftsmanship with the development of modern technology, they have found a suitable path.

After the combination of fire needle pricking and bloodletting, Chen Nan's operation really began.

Percutaneous superficial vein surgery requires precise identification of blood vessels and then related ligation work.

This is a great test of the surgeon's ability.

This time, everyone was cautious.

They also tried percutaneous superficial vein surgery, but this surgery was too difficult!

Today's percutaneous superficial vein surgery is completely different from what Chen Nan first studied.

The opening is even smaller. After strict requirements, only a 1.5 cm opening needs to be opened. This opening allows for many operations.

If Chen Nan hadn't given Ruan Yongyi many demonstrations, Ruan Yongyi would be in trouble now, because at the beginning, his opening was three centimeters.

Don't underestimate the gap of only 1.5 centimeters. The smaller the wound, the more in line with the current concept of minimally invasive surgery. Those laser instruments even require a lot of incisions to find blood vessels and insert the tubes before they are improved to 2

About centimeters.

How could Chen Nan use 1.5 centimeters to complete the operation?

This is the detail of the surgery that attracts the most attention.

When Chen Nan cut the wound decisively, Chang Ruyi quickly stopped the bleeding, but he only used two pieces of gauze because the bloodletting just now had significantly reduced the pressure on the target blood vessels.

The choice of incision is the most important.

You can deny a traditional Chinese medicine doctor's anatomy skills, but don't underestimate his grasp of the circulation of acupuncture points and meridians of the human body.

In fact, the prerequisite for small incisions in percutaneous superficial vein surgery lies in the selection of the opening point.

Compared with traditional high ligation of the great saphenous vein, Chen Nan does not need to operate on the great saphenous vein.

For example, the great saphenous vein is equivalent to a main valve.

Varicose veins of the lower limbs refer to the elongation, meandering and dilation of the superficial venous system of the lower limbs - the great saphenous vein, the small saphenous vein and their branches.

It has many branches, the most important of which are the five obvious superficial veins: the superficial circumflex iliac vein, the superficial abdominal wall vein, the superficial external abdominal vein, the superficial medial femoral vein and the superficial lateral femoral vein.

It is obviously impossible to perform surgery by needling multiple branches.

Otherwise, the difficulty of an operation will increase a lot.

The simplest way is to destroy the main valves of these superficial veins.

However, there are bag-shaped valves in both the great saphenous vein and the small saphenous vein. There are 9 to 15 pairs of valves in the great saphenous vein and 6 to 12 pairs in the small saphenous vein.

The destruction of these valves is the main cause of varicose veins.

The destruction of the valve causes the femoral vein blood to flow backward into the great saphenous vein, causing varicose veins in the lower limbs.

Some people may ask, wouldn’t it be simpler to repair the valve?

But, how many people can afford this cost?

The price of a biological valve ranges from several thousand to hundreds of thousands.

How much do you change?

This is just a minor surgery. Just closing the main valve of the great saphenous vein or the small saphenous vein can solve this problem.

However, this will cause more damage to the blood vessels!

Similarly, to treat blood vessels such as the great saphenous vein and the small saphenous vein, larger incisions are required and there are more hidden dangers.

Only then did subsequent improvements come about.

The purpose of improvement is still to destroy large blood vessels.

However, the participation of fire needles gave Chen Nan more options to treat multi-point damaged blood vessels.

He can use the many functions of fire needles, such as carbonization, activation, promotion... etc. to effectively and accurately deal with small blood vessels that have damaged valves.

Then, select a branch to make an incision, perform surgery, and deal with the broken branch.

Just now, Chen Nan has found a suitable surgical site for the superficial medial femoral vein and made an incision.

After Chang Ruyi cleaned up the blood stains from the wound, everyone stared at the big screen and was stunned for a moment!

"Where's the wound?"

…

This question surprised everyone present.

Because they couldn’t find an opening in the skin for a while!

How is this going?

Ruan Yongyi disagreed in his heart. Looking at everyone's reactions, he smiled and shook his head.

Do you really think our improved techniques will be so easy to learn?

If that were really the case, I would have been so awesome a long time ago.

However, when the red blood seeped out, everyone stared at the wound with wide eyes and said in surprise: "Such a small wound?!"

"This is only...1 centimeter, right?"

"yes!"

"Will this work?"

"How can you solve the operation in one centimeter?"

"Didn't your paper say 1.5?"

Ruan Yongyi laughed heartily, but remained calm. He said in an ordinary and normal manner: "Oh, the purpose of writing 1.5 in our materials is not to increase everyone's psychological burden and difficulty of the operation. We have already

It has exceeded the 1 centimeter mark!"

Listening to Ruan Yongyi's invisible pretentious tone, Xing Daqing and Zhang Zhixin on the side became angry and itched their teeth.

At this time, Chen Nan started his operation.

His slender fingers entered the wound like a worm. It didn't take long for him to find a tortuous blood vessel.

This process was so fast that everyone took a breath of cold air.

"I...I'm going to go?"
