Chapter 1392

The operation of patients with vegetative disease started the next morning. Jiang Ming and Huang Haitao, two academicians, participated in the operation this time. It can be said that Xiangyun hospital's top strength was mobilized to ensure the success of the operation. However, the two academicians were willing to act as assistants and let Chen Qun preside over the operation.

This is Chen Qun's operation, not the two of them. They participated in the operation just to learn and provide some experience help. Because both the two academicians participated in the operation, another professor in charge of brain surgery volunteered to act as the third assistant. Only Chen Qun kept the nurses and other medical staff of the operation team.

This is an unprecedented experimental operation with high risk, but both the family members and the hospital are willing to try it. In particular, Chen Qun, the family members of the two patients, showed them a variety of pictures of the patients, and knew that this should be the only chance for the patients to get rid of the vegetative. Otherwise, even if the patients were sent to the best Mayo Clinic in the world, they might not be able to get this kind of experimental operation with the participation of supercomputers.

However, everyone who participated in this operation knows that the difficulty of this operation is not purely technical operation, but in terms of theoretical reasoning. In fact, it is simple and straightforward to open the patient's head, and then use electrodes to stimulate each specific area to see which part can activate the patient from a vegetative state.

This requires theoretical level and rich brain experience, so Jiang Ming has become the first assistant.

About 20 minutes after the operation, Chen Qun finished all the preparatory work, and a slightly beating brain ball appeared in everyone's field of vision.

Chen Qun took a look at everyone and gave the specific direction of his operation again.

"Specifically, we are stimulating the core of the patient's medullary lamina to find a specific area with obvious brain wave changes. Although the Supercomputing Center has done numerous simulation operations, there is a certain difference between this and the actual effect, so we need to do the things simulated by the Supercomputing Center again, upload the actual data, and simulate new results again. "

Jiang Ming knows that the difficulty of this operation lies not in the surgical part, but in the part of determining the location of the operation, which is like looking for a needle in a haystack. However, Xiao Chen never believed in luck. Instead, he made specific arrangements, dividing the area to be stimulated into hundreds of areas, and establishing key areas and non key areas according to the weight ratio.

Looking at the patient's brain, academician Jiang said with a sigh.

"From where we stand now, the patient's brain is like a globe. Each region has its own unique language and culture, which governs different physiological functions. What we need to do is to find the right wave frequency, and we will know where to lower the electrode, so as to activate the patient. "

Chen Qun at this time but a dignified appearance, to the side of the young lady command.

"Give me electroacupuncture, first determine the brain wave signal of thalamus!"

At his command, a synthetic metal needle, thick as hair, slowly penetrated into the patient's thalamus from his hand. With the connection of the electrode on the electroacupuncture, several groups of obvious brain waves and a slight buzzing sound appeared on the display screen nearby. As soon as it rings, it becomes a rising and falling sound like breathing, full of vitality.

"The sound wave signal of thalamus is clear and all data are normal. Start the first level voltage test and set the voltage to 1 V!"

As a group professor of the third assistant, he immediately turned the voltage button to one volt unit on the scale in his hand. As for the two academicians who served as the first assistant and the second assistant, they were standing beside and opposite Chen Qun, idly looking up at the data on more than ten screens.

With the increase of the voltage, the original rhythmic brain wave acoustic signal immediately becomes a bit hasty, and becomes the sound of walking fast.

"Thalamic wave baseline Figure 1 has been determined, now start the test of each area! Academician Jiang, this is your field, please operate it! Xiao Xin and I are going to compare the data! "

Chen Qun said as he made way for his position. Dongfang Wenxin, who is next to him, sings with her husband and wife. Together, they leave the position of the instrument nurse, and Zhao Xue, who acts as a substitute, immediately stands up.

The next boring test, Jiang Ming will inhale cattle hair electroacupuncture one by one according to the position of the front three-dimensional projection diagram to micro test, because there is a three-dimensional projection diagram in front and make records, at the same time in his palm, he did not test an area, there is a straight green light on it, Leave a clear green spot in the cerebral cortex to mark.

Looking at this change in details, Jiang Ming also sighed that if they were doing this test in his own operating room, their marked areas would be pasted on the brain with stickers as big as nails with full numbers to avoid mistakes.

But now with computer marking and recording, the damage to patients is less, and it can record everything more comprehensively.In the twinkling of an eye, electrode tests were carried out in dozens of regions, and different fluctuations and reactions of brain waves also appeared, but the brain wave waveforms of normal people they needed still did not appear.

In other words, the test in dozens of areas in two hours has no effect.

Jiang Ming put down the electroacupuncture in his hand and directly asked the couple who were still buried in the computer for data statistics.

"Xiao Chen, all areas can't wake up the patients. What's the statistical result on your side? What's new? "

Chen Qun's head did not lift.

"Give us a few more minutes. Xiaoxin is changing her algorithm and doing some statistics again!"

As he spoke, he subconsciously glanced at the next picture of thalamic acoustic signal. He knew that in all the tests, there was an interesting phenomenon in this picture of acoustic signal, which was also the reason why he asked why he wanted to convert brain waves into sound waves.

A few minutes of waiting is common for brain surgery. After all, among all surgical operations, brain surgery is the most delicate. As long as it is not massive bleeding, we can operate slowly. Even many operations need to be tested and operated at the same time.

In the twinkling of an eye, a three-dimensional waveform, or more like a funnel, appears on the large screen of the operating room. The results show that the sound of dozens of thalamic sound waves in different positions has obvious difference in plane, especially in the part near the nucleus pulposus.

Chen Qun pointed to the picture.

"This is the sound wave image of the thalamus that controls the consciousness of the brain. We all know that this part of the brain has a special part of the pedunculopontine nucleus. From the stimulation results, we can see that in the core of the midbrain, the stimulation is the least. Therefore, from various statistics, if we want to wake up the consciousness of patients, we need to go deep into the core of the midbrain and stimulate that part, It is most likely to awaken the patient's consciousness. "

As soon as Chen Qun finished, Jiang Ming frowned.

"But then the core area, we have never been involved, it is very likely that we will damage other parts and kill him."

"Yes, we may have killed the patient, but I'll try to make sure it doesn't happen. We'll try again, and if there's no response, we'll stop the operation. "
