Chapter 321 Brain-Computer Interface

 Gao Qiao arrived at the department on time at six o'clock in the morning. Following Zhang Lin's request, after completing his work, he started making tea for him.

He weighed twenty-nine tea grains with an electronic scale and wrote them down in his notebook. He decided to start from today's weight and add or subtract based on Zhang Lin's satisfaction until he found the optimal tea weight.

Takahashi also recorded and calculated the time for making tea, the time for making tea, the time for Zhang Lin to go to work, and the cooling speed of a cup of tea to ensure that Zhang Lin could drink it warm when he went to work.

But it’s a tea that doesn’t burn your mouth.

In Japan, Takahashi also knows a little bit about the tea ceremony, but after all, China and Japan are different, and Dr. Zhang's simple tea making has a satisfactory taste, which all depends on meticulous experience.

"Takahashi, you bought the electronic scale just for making tea?" Li Guodong thought he was doing some experiment.

After making the tea, Takahashi was very satisfied with his work. He rubbed his hands and said, "Yes, these tea particles are of different sizes. It is difficult to achieve accurate measurement by counting the particles. Only accurate weighing can achieve accuracy."



The Japanese are too stubborn in doing things. They just make tea. They actually use an electronic scale with an accuracy of 0.001 grams. This is an experimental attitude to make a cup of tea. Li Guodong is an eye-opener.

Gao Qiao was so involved in helping Zhang Lin make tea without any complaints. From the arrogance and rudeness before to the humility and obedience now, the transformation speed was so fast that Li Guodong could not believe it.

Xu Zhiliang also came to the department early to report that he is a doctor of orthopedics. After graduation, he could not find a decent professional job. In order to stay in a better hospital, he changed the hospital and entered the emergency department. Today he finally got his wish.

Opportunity to enter orthopedics and return to the profession.

He greeted everyone with a nod and a smile. Some of the nurse girls, those who knew him, covered their mouths and snickered because he stuttered. I heard that the pants he wore had holes in his buttocks, which was quite unusual in the hospital, and some secretly peeked at his buttocks.

, but covered by a white coat, I don’t know if there are really holes.

Professor Zhang Da's life is now very smooth. He sat down in front of his desk. The tea, which had turned from scalding to lukewarm, was already placed on his desk. He unscrewed the lid leisurely and took a sip: "Yes, there is.

Progress, it’s still a little bit thicker.”

Takahashi stood aside, listening attentively to Zhang Lin's feedback, and immediately wrote down the feedback in his notebook, and began to appropriately reduce the amount of tea tomorrow.

Being secretly looked at, Xu Stutter didn't take it seriously, and automatically stood in an inconspicuous corner, studying the erect human skeleton alone.

Yang Ping came in from the door. Everyone immediately stopped what they were doing, stood up, and said in unison: "Good morning, Dr. Yang!"

Over time, something called prestige gradually settled in everyone's hearts. Xu Zhiliang was studying the skeleton and stood up straight, greeting him with reverence.

Being able to show off his talent under such a person and having no regrets in his life made Xu Zhiliang feel high-spirited and excited.

There were several operations in the morning, including operations for lumbar disc herniation, cervical spondylosis, pelvic tumors, and one percutaneous kyphoplasty. Yang Ping asked Xu Zhiliang to perform the surgery. He wanted to see his surgical skills. He was on the stage.

From the looks of it, there won’t be any safety issues.

As soon as Xu Zhiliang had the operation, he looked like a completely different person. He was confident and calm, spoke and moved neatly, and did not stutter at all.

Zhang Lin couldn't believe it. This was Xu Zhiba. There were several times when Zhang Lin disobeyed the surgeon's instructions and was scolded severely by Xu Zhiba. Yang Ping just laughed while watching on the stage.

After several surgeries, Xu Zhiliang not only performed the surgery in a standardized manner, but also performed very quickly. His basic surgical skills were also very good, and he could almost catch up with Song Zimo.

It’s no wonder that talented people are so bold that they can extend the abdominal wound at the emergency scene, reach in to block the aorta, and stop the bleeding with bare hands.

Yang Ping suddenly felt like he had found a treasure. He went to the Human Resources Office to interview several doctors, but none of them were satisfied. He actually let himself choose the treasure in the emergency department.

A few operations showed his level, and there was no need for a three-month probationary period. After the operation, Yang Ping said to Xu Zhiliang in the locker room: "I'll make a call later. Tomorrow you go to the Human Resources Office to go through the transfer procedures."

."

"No need---three months trial---use--use--has it expired?" Xu Zhiliang is already ready for a three-month trial.

Yang Ping shook his head: "No, others have to try it for three months. You Xu Zhiliang only needs to try it for one day. From now on, you will work hard in the Department of Comprehensive Orthopedics. If you need anything, just tell me directly. If you find WeChat convenient, just send it to me."

Xu Zhiliang nodded gratefully: "Is this --- passed ---?"

I was so excited that I held the last word for a long time before spitting it out.

"Full score passed!" Yang Ping said with satisfaction, and Gao Qiao also gave Xu Zhiliang a thumbs up.

Zhang Lin always has the desire to show off to newcomers, but on the operating table, he was scolded by Xu Zhiliang and lost his temper. He is still angry. How can he dare to show off such a stutter? Xiao Wu snickered on the side

, Zhang Lin is just pretending to be cool, he has become a cool guy himself.

In the afternoon, the Department of Comprehensive Orthopedics discussed Yu Shuilian's case in the conference room, learned about the patient's rescue and surgery, and also discussed the next treatment plan.

Yu Shuilian's condition is temporarily stable, and Song Zimo also took the time to participate in the case discussion in the department. Everyone gathered together and the atmosphere was very good.

Xu Zhiliang was very excited when he saw Song Zimo: "Dr. Song, I have long---looked up to you---"

"Long time admired!" Song Zimo shook hands with him.

I still know Xu Zhiba from the emergency department, but I haven't interacted with him much. I just played chess a few times. I heard from Yang Ping that he joined the orthopedics department. Song Zimo didn't know that this stutterer was also a major in orthopedics.

"What---when---play---a game of blind chess together?"

"Are you still playing blind chess with me?"

In the chess and card game of Sanbo Hospital, Wen Zhong from the spinal surgery department lost to Song Zimo in chess, and Xu Zhiba from the emergency department also lost to Song Zimo in Go. Xu Zhiba has always been grudges and is unconvinced.

Xiao Wu came over with a few puzzle pieces and placed them on the table in the conference room.

"What are you doing with these?" Zhang Lin asked.

"Wait a minute - the lecturer - where are the teaching aids." Xu Zhiliang said angrily.

Zhang Lin glanced at him and was afraid of him, so he had to stay away from him and did not dare to sit next to him.

Doctors, graduate students, trainees and interns all arrived, and the case discussion began at three o'clock in the afternoon. The next treatment plan was discussed first, and then Yang Ping explained the key points of the operation.

Song Zimo has been taking care of this patient in the ICU. As the doctor in charge, he reports on the case: general situation, medical history, physical examination, auxiliary examination, diagnosis, treatment process, current difficulties encountered, and next treatment plan.

"The main risks she faces now are infection and organ failure. Fortunately, so far, there has been no infection or organ failure." Song Zimo asked the question.

"If she can overcome the two life-and-death hurdles of infection and organ failure, then we will consider a second-stage surgery to reconstruct her anus and urethra and establish her urination and defecation function." Xu Zhiliang is very positive and does not stutter.

"For the reconstruction of the urethra, I recommend multi-curvature reconstruction. From a normal anatomy, the female urethra is shorter and straighter than the male. Bacteria invade the urethra from the outside and enter the urinary tract through a short and easy path. This is why women are prone to urinary tract infections.

Reason." Takahashi rushed to express his opinion. Halfway through, he looked at Yang Ping.

Yang Ping nodded to encourage him, and then he continued: "This patient's urethra has been damaged. If we use a straight and short method to reconstruct it, urinary tract infections will still occur easily. Her ability to resist infection is worse than that of normal people.

In order to reduce the probability of urinary tract infection in the future, I recommend using multi-curved long-path urethral reconstruction to reduce the probability of urinary tract infection in the future."

Generally, case discussions are based on the doctor's professional title, from resident to attending, then to associate senior, to senior, and then gradually upgrade, and finally the department director summarizes.

However, in the comprehensive orthopedic case discussion, Yang Ping broke the rules. Participants were free to speak regardless of their hierarchy. Finally, Yang Ping summarized everyone's opinions.

"The patient finds it difficult to accept his disability and needs to rebuild his mental state. I suggest that based on this patient's individual situation, the psychology department designates a complete psychological counseling plan and conducts long-term psychological counseling and reconstruction."

A graduate student spoke.

"Very good! Everyone spoke very enthusiastically, don't be afraid of making mistakes." Yang Ping encouraged everyone.

A trainee mustered up the courage: "This, that, the patient is still in the ICU. I think it is best to let her son and husband visit her in the ICU ward once a day. It is best to make her son a little sloppy, so that she can see her poor son.

If you can't bear it, muster up the courage to live. This is more useful than any psychological counseling."

Another girl rushed to say: "I know that there is a disabled person who lost both lower limbs from the top of his thighs, and later became a calligrapher. He is quite famous. You can contact this calligrapher and let them meet. Let Yu Shuilian use a living example.

Know that if you continue to live, you are not a waste. Your life is completely valuable, and it is valuable to your family and society."

"Instruct her to train the strength of her upper limbs early so that she can walk with her upper limbs in the future."

The discussion was very active, everyone started to make associations, tried their best, and spoke freely.

"Actually, we can be more optimistic. If she can successfully survive the dangerous period, she can use the armpit and chest wall for support in the future and use brain-computer interface powered prostheses." Song Zimo seemed more optimistic.

Xu Zhiliang was not to be outdone: "Musk has a company that is researching brain-computer interfaces, and it is at the forefront of the world. They use monkeys to conduct experiments, and they can use brain-computer interfaces to train monkeys to use robotic arms to eat."

"The International Electrical and Telecommunications Basic Technology Research Institute (ATR) in Kyoto, Japan, has produced a practical robotic arm. If necessary, I can contact ATR. We have cooperated with them to develop powered braces for patients with lower limb paralysis. In spinal cord injuries,

It was used on patients and the experiment was very successful." Takahashi's participation is getting higher and higher.

"The Stanford team in the United States also has a successful case. The article was published in Nature. They have entered into human experiments. The experimental subject was a paralyzed patient. When the patient tried to make hand movements, functional magnetic resonance imaging was performed on his brain to determine the movements.

The precise area of ​​the cortex. Then a chip is implanted in this area of ​​the patient's brain. When the patient wants to move his hand, the motor nerve signals are translated into electrical pulses to drive the muscles on the arm, stimulate the electrodes, and make the arm muscles contract as desired. Complete

You can even perform movements such as palm-palming, flexion and extension, and grasping, and you can even play games and play the guitar." Song Zimo's introduction was very effective, and he actively followed up.

Originally, we just wanted to discuss the next step of the second-stage reconstruction surgery. Unexpectedly, everyone was so enthusiastic, and they continued to discuss how to make Yu Shuilian stand and walk.

It seems that they are all powerful figures who can see high and far. Yang Ping is very happy.
