The medulla oblongata, connected to the upper cervical medulla, is the size of a fingernail and lies under a microscope.

Inside, large and small nerve nuclei, each of which is closely connected to life.

The scalpel takes a wrong step, and the patient dies directly on the operating table.

Yang Ping's movements began to slow down, minimizing the damage to the tissue from the tip of the knife, and completing every step of the operation with the gentlest and most precise movements.

The laser knife cuts through the medulla oblongata and the cervical spinal cord tissue attached to it, penetrating little by little, and entering very slowly.

The data on the monitoring screen fluctuates up and down, heart rate, breathing, blood pressure, blood oxygen saturation, etc., each data represents the patient's vital signs.

Liang Fatzi stared at the data on the screen tightly, not daring to slack off in the slightest, and once there was any abnormality, he would report to Yang Ping at any time.

Cardiovascular center, cardiac acceleration center, decompression center, cardiac inhibition center, respiratory center---

Countless centers are concentrated in this fingernail-sized place, and the connections between them are intricately intertwined, and the slightest injury can kill the patient.

You only have one life!

The laser knife works perfectly with bipolar electrocoagulation, and the blood is almost invisible in the surgical field.

This is the true bloodless operation, the highest level of surgery.

"Every step is extremely dangerous, if you change to someone else, the operation will end here, and it will be impossible to continue, and the 0.1mm laser knife can exert real power in his hands." Ikeda muttered.

Ito also held his breath, and the more he learned about the operation, the more nervous he became, knowing the risks at every step.

The tip of the knife is impartial, making an incision between the two nuclei and the tumor is detached from the surrounding tissue little by little under the knife.

"The geomagnetism, celestial phenomena, ocean currents, and air currents of the great voyage are all chaotic, and it is difficult for the navigator to even confirm his position, let alone find those islands, the navigation technology and experience in the four seas in the past are useless, only the recording pointer and the permanent pointer are trustworthy, and now we are facing this great route, there is no record pointer and permanent pointer, how can we avoid the dangerous reefs and rapids, and reach the target safely?"

Ito gradually changed his opinion, and it turned out that the young man was indeed the only one who could have had the operation.

There is no need for anything to corroborate it, and the patient's heartbeat is still there, which is the best proof.

"This is just the beginning of the paradise, the second half of the new world is the most dangerous, if I guess correctly, at that time, the heart rate will be compressed to several times per minute, no different from death, can not use artificial heart-lung machine to replace, can not let the heart temporarily stop, can only let it stay in such a state, in this state, the heart blood supply is far from meeting the needs of the body's vital organs, especially brain tissue, two to three minutes, that is, Dr. Yang will have to within two to three minutes, cross the narrow danger zone, once delayed, The heart rate will eventually drop to zero, zero forever! Ikeda and Ito, their eyes glued to the screen, talked in a low voice.

Ito said slowly: "There are seven magnetic forces extending from the Upside Down Mountain, no matter which one you choose, no matter which island the magnetic force starts from, once you choose, you can't change it, you can only go down one island by one along this channel, and finally these seven routes will converge to the Chambord Islands, and when you arrive in the New World, you can choose a new channel, and the last island you reach is the end of the great waterway, Lovedrew." We had done countless experiments and dissected hundreds of cadaver specimens to find these safe passages, but unfortunately, none of them were found, and now he seems to have found them. ”

"Probe imaging technology didn't help him much."

"He should have his own set of positioning techniques."

"What a pair of hands, so stable, so gentle, so delicate, so dexterous!"

"A hand made for surgery!"

The laser knife follows this path, going deeper and deeper, and accomplishing such a delicate and complex operation on the tissue with a large nail cover.

---

Even the gentlest operation is prone to subtle damage to the nerve nuclei due to thermal damage, traction, squeezing, and friction.

The tip of the laser knife in Yang Ping's hand had almost no contact throughout the whole process, and the operation was completed by laser cutting, but thermal damage could not be avoided.

That's why he was so slow, trying to avoid the accumulation of heat.

When the compression of the tumor is lifted little by little, the external environment of the nerve nucleus will change, and this change will also cause some risks.

The heart rate and breathing are getting slower and slower, and this slowing cannot be intervened with drugs, and once it is intervened, it is disrupted and can cause the collapse of the entire living system.

Daisuke Komori and Fusuke Mitsui, who had planned to work together to deal with this case, stared at the screen in the operating room and fell into a deep silence.

With their strength, they simply can't get this far.

They are the top professors of the University of Tokyo, not laymen, and when they saw this, they understood a little.

---

The doctors from all over the world at the meeting seemed to have forgotten that they were here to see the operation.

Even if you are not a doctor in this specialty, you are struck by such superb surgical skills, which is the limit of human hands.

Dr. Lim Ming Yuen from Singapore is communicating with doctors from Australia.

Professor Liang sat with Professor Su and Professor Qin, and was very satisfied with this rising junior.

Professor Su was very happy in his heart, but he wondered why this girl didn't bring Xiao Yang home.

He couldn't wait to recognize this son-in-law.

The only one who is more depressed is Professor Qin, the work of poaching people has not progressed for a long time, and the upper authorities have been constantly pressuring, and a lot of work has been done, but it has no effect.

Other young doctors have now become fans of Yang Ping, and everyone looks to Yang Ping as a role model.

For example, Song Yun of Xiehe, who studied with Hu Guolin in Sanbo for a period of time, has gained a lot, and now he has also joined Yang Ping's research on the experimental topic of external spinal fixation, and Song Yun is also one of the protagonists.

---

The patient's heart rate is getting lower and lower, it has fallen below thirty, and it is still falling.

The isolation of the tumors is already close to the heartbeat center, and they also have some kind of adhesions, which is very tricky.

Probe imaging can only serve a general identification role under the microscope, and it is not helpful for the delicate operations that Yang Ping requires, but Yang Ping is too familiar with the dissection here, and he can complete dangerous operations accurately even without any assistance.

When the patient's heart rate fell below 30 beats per minute, Mitsui and Komori's hearts trembled.

Now, with every fall, it means that the patient is one step closer to death.

They sat motionless, and the patient lay not far from them, and they could really feel the imminent death of the knife.

Japanese anesthesiologists, instrument nurses, and itinerant nurses have set their sights on Mitsui and Komori at the same time.

The request needs to be intervened at this time, and if you continue, your heart will definitely stop.

However, at this time, Komori and Mitsui were powerless, and they lacked experience in this area.

Even if Yang Ping asked them to come to the stage to rescue them now, they didn't know what to do?

Using a temporary pacemaker?

Replacing the work of the heart with an artificial heart-lung machine?

Or simply arrest the heart and use cardiopulmonary bypass?

No, once these technologies intervene, the feedback mechanism between the heart and the spinal cord and the brain is inhibited, and once it is suppressed, it is followed by collapse, and once it collapses, there is no way to return to heaven.

Modern medical techniques sometimes seem powerful in the face of the complex human body, but sometimes they seem very pale and weak.

Mitsui's eyes fell on Yang Ping, who was concentrating on the operation, and Yang Ping didn't seem to be worried, and seemed confident.

It seems that this situation is often encountered, and it has become commonplace.

Finally, the heartbeat fell to only a dozen beats per minute, and it was on the verge of death.

This is the narrowest area of the two nerve nuclei, so narrow that they almost stick together, and the tumor squeezes through the middle and becomes thin.

Suddenly, the heart rate dropped to 10 beats per minute, and it was still falling, no different from death.

Cells throughout the body enter a state of hypoxia, as if suffocating.

The Japanese anesthesiologist and nurse looked at each other, Mitsui and Komori did not move, they were very anxious.

The heart falls below 10 times per minute.

"10 times!"

Liang Fatzi began to count, his tone was calm, and it was obviously not the first time he had encountered such a situation.

10 times !!

Mitsui and Komori stood up almost at the same time and yelled.

Rescue!

Hurry up and rescue!

If the brain is not resuscitated, the brain will be brain dead after eight minutes due to ischemia, and the heart rate of ten beats will not be able to maintain the perfusion of vital organs.

Japanese anesthesiologists and nurses heard the shouts and reflexively moved into action.

The operating room began to stir.

"Eight Tooth Road!"

Zhang Lin glared angrily and roared, he and Xiao Wu blocked Xiao Sen and Mitsui at the same time, telling them to stay where they were and not to act excessively.

Tang Shun actually forgot how to translate.

Originally, Zhang Lin spoke in Japanese, and there was no need for a translator at all.

It was this imposing "Eight Grid Tooth Road" that played a huge role, Komori and Mitsui froze, and then forcibly sat down, their foreheads were full of sweat, and they didn't dare to move again.

The Japanese anesthesiologist and nurse, who were just about to act, also stopped their movements under the roar of this "eight-grid tooth road".

Everyone came to their senses.

The main knife is not them, but the Chinese, and several of them only symbolically cooperate.

Screaming like this all of a sudden can seriously interfere with the surgery.

Three minutes is the golden window, there are only three minutes, and the danger phase must be crossed within three minutes, otherwise, the patient will die.

Not to mention three minutes, even thirty minutes, no one can complete this step of separation.

Mitsui and Komori's breathing was a little rapid, and the Japanese anesthesiologist and nurse were also anxious.

Unlike their panic, the Chinese team acted as if nothing had happened.

Yang Ping was completely unaffected by them, steady as Mount Tai, breathing smoothly, and continued the operation.

Song Zimo and Xu Zhiliang were the same, unmoved.

The instrument nurse still sits there quietly, placing the next equipment in a convenient place.

The anesthesiologist crossed Erlang's legs and stared at the screen.
