Saturday, at nine o'clock in the morning, the meeting started on time.
The large conference room of Sanbo Hotel was packed with seats, and the front row was also filled with guests.
As of nine o'clock, the number of participating delegates exceeded 2,000. If 1,000 people come to this kind of academic conference organized by a hospital, it will be considered very successful. Now there are more than 2,000 registered doctors attending the conference.
The large conference room of Sanbo Hotel can accommodate up to 1,000 people, and temporary stools are needed to accommodate this.
According to the plan, in addition to the main venue, six branch venues will be opened. The branch venues will use large screens to watch the speeches of the guests, and the question and answer session with the guests can be completed using the video call function.
The mobile company cooperated with Sanbo Hospital and used 5G technology to help Sanbo build a video system for the entire venue. They also took this opportunity to promote 5G.
After Director Tan finished his opening speech, he introduced the guests attending the meeting.
Then he began to show everyone the current situation of the Department of Microtrauma and Orthopedics of Sanbo Hospital, especially the case of five-segment replantation as a signature promotion.
This surgery has complete video information and is the most convincing, and the surgery patient Xiao Guoqiang took the initiative to apply and stood on the podium to demonstrate the body functions.
Director Tan’s speech will be in English, and all other guests will use English. It is positioned as an international conference, and it would be unreasonable not to use English.
The team led by Tang Fei is responsible for on-site translation. She went to a Chinese-English bilingual school in elementary and middle school, so her English speaking and listening skills are very good. She is a doctor, so her translation is no worse than professional translation. She also translates medical terminology
will be more accurate.
Translation, in order to make the participating doctors understand, because the vast majority of doctors do not have the ability to listen and listen in English. Even if they have passed CET-4 or CET-6 in school, they are all mute in English. They can do the questions, but they can really listen.
Say no.
Qiangzi was a little nervous in the backstage of the conference room. His girlfriend comforted him: "It's okay. Just relax. Just follow the doctor's instructions and demonstrate to them. Just pretend it's Director Han and Dr. Yang in front of you."
Doctor Che, who was in charge of Qiangzi's rehabilitation, once again guided the movements that needed to be demonstrated, and Qiangzi followed them carefully.
This five-segment replantation was very sensational at the time, and almost all orthopedic trauma surgeons across the country knew about it. Everyone marveled at the superb technology of Sanbo Hospital, but at the same time had no hope in the function of the replanted limb.
Everyone feels that Sanbo Hospital performed this surgery solely to gain eyeballs. Maybe after a while, the limbs will be amputated because they have no function and become a burden.
Everyone wants to know whether the limb is functional or whether it will be amputated in the end, and many doctors are here to get it.
Director Tan originally planned to make a video to show the post-operative function, but after Qiangzi learned about the situation, he took the initiative and asked to go to the venue to demonstrate in person.
There is no problem with the blood supply of the replanted limb, and the muscles and tendons have healed. The most challenging thing is the repair of the nerves.
According to the electromyography test, the nerve has grown to the wrist, which is in line with the average growth rate of one millimeter per day.
Nerve rupture is different from the repair of ruptures in other tissues. Other tissues heal, but nerves are different. Once a nerve is ruptured, the distal section will be completely useless, the nerve fibers will disintegrate, and finally an empty shell tube will remain.
To repair the nerve, the nerve near the end of the fracture grows in from the tube left at the far end. It must grow all the way to the end of the limb in order to have good function.
The higher the location of the nerve cut, that is, the further away from the end, the less likely it is to grow through. Those tubes are big tubes inside small tubes. There are many nerve fibers and the tubes cannot be found. If there are no tubes, they will not grow.
Just like a train without tracks, it can’t move.
The nerves of the limbs are divided into motor nerves and sensory nerves. They have different functions. One is responsible for muscle movement, and the other is responsible for skin sensation. When many nerves grow at their stumps, they will be drilled into the wrong tube, and the motor nerves will be drilled into the sensory nerves.
The tube, the tube from which the sensory nerves are drilled to the motor nerves, if drilled wrongly, will have no effect if it grows longer.
In this way, many factors lead to the poor recovery of peripheral nerves, especially the recovery of high-level nerve injuries, which is a worldwide problem.
Hadron's nerves reach the wrist, and the muscles of the forearm gain control.
The dorsiflexion and flexion of the wrist joint are very good, and the flexion and extension of the five fingers are also very good. However, the opposability of the thumb and the adduction and abduction of each finger are not good, because these movements are driven by the muscles of the hand, and the nerves are still there.
It has not grown and is not connected to the muscles of the hand.
Judging from the current growth trend, these last five centimeters should be long enough.
Hadron demonstrated holding dumbbells to perform resistance activities at the elbow and wrist joints, and holding the ball with five fingers.
If you wait another two months, you will probably be able to write and use chopsticks easily. At present, the intrinsic muscles of the hand have not yet received innervation, and without the cooperation of the thumb's palm action, it will be difficult to hold a pen and chopsticks.
Five-stage replantation, which took half a year to achieve this effect, has been very successful.

Yoko judged the traffic situation in G city very accurately. At about 8:30, she sent Miyuki Fujiwara and Fumiya Takahashi to Sanbo Hospital on time.
Fujiwara Miyuki and Takahashi Fumiya naturally became the focus of the meeting.
Miyuki Fujiwara is the winner of the Victoria's Secret Fashion Show and the only one doctor in the world. As a doctor at the University of Tokyo Hospital, Fumiya Takahashi became famous very early. He is often active in various large-scale international conferences and is a leader in trauma surgery.
Character.
For example, at the North American Trauma Surgery Annual Meeting, he was invited as a guest and sat in the front row. It is estimated that only his teacher Masao Fujiwara and him can have this status in Asia.
After listening to Director Tan's introduction, Takahashi touched his chin. Five-segment replantation of the upper limb was impossible to achieve good function. Takahashi Fumiya had a clear judgment on this.
This is just a gimmick for the conference. There is really nothing to bring out. We can only take the severed limbs that we are good at and replant them. As for the function, we will wait and see.
From the beginning to the end, Takahashi was reluctant to participate in this small meeting and was very resistant. Behind every seemingly sincere etiquette was arrogance and prejudice.
He didn't even take the initiative to talk to the Korean doctor next to him. When someone asked him a question or two, he responded bluntly, hoping that the meeting would end soon. He was here to complete the homework for the teacher.
The surgical video of the replantation of a severed limb is shocking, and the speed and rhythm of the operation are incredible. However, Takahashi believes that the video is suspected of editing, so just watch it.
As a great figure in trauma surgery, he is very clear about the difficulty of this five-segment replantation.
If the nerve can grow smoothly, it needs to cross five fractures, which requires very advanced nerve suturing technology. It is feasible in theory, but no one can do it in practice.
If you can’t do it yourself, who else can do it?
Takahashi decided that if he had the opportunity, he would personally check the patient's functions, but he didn't know if he would be given the opportunity.
I had no interest in the meeting at first, but when I thought about it, I suddenly became very interested, just like an audience determined to expose a magician's trick.
The topic of Takahashi's speech today is the application of infrared monitoring equipment in trauma surgery, especially the use of hemoglobin fluorescence imaging technology, coupled with excellent computer algorithms, allowing trauma patients to become transparent on the operating table. This technology is currently unique in the world, making it almost impossible to make mistakes in hemostasis on the operating table.
Mr. Fujiwara’s next goal is to overcome the repair of peripheral nerve damage. He also uses infrared technology and uses a nerve fiber cleaning agent to make the motor nerves appear red and the sensory nerves appear blue under infrared rays. Then these images are combined with the camera system
After integration, the image of the captured nerve fibers on the final screen is divided into clear blue and red.
In this way, blue versus blue, red versus red, there will be no mismatching of nerve anastomosis, and the effect of nerve recovery will be doubled.
There are two factors for poor nerve recovery: first, the loss of nerve fibers caused by incorrect nerve growth; second, the slow growth rate of nerves leads to degeneration of target organs.
At present, the University of Tokyo Hospital has solved the first factor, and the second problem is in experimental status. Although it is immature, it can be broken through soon. If these two problems are solved, they will conquer a world problem.
The second problem is that the growth rate of nerves is too slow. Motor nerves innervate muscles. Sometimes, nerves grow by chance, but muscles degenerate and become fibrotic because they have not been innervated for a long time. Muscles are no longer muscles and become
Fibrous tissue, even if it is innervated, cannot complete its contraction function.
To overcome the second problem, we must either speed up the growth of nerves or keep the muscles in a normal state for a long time without being fibrosed.
Takahashi is currently studying this topic to increase the growth rate of nerves and combine with their target organs as soon as possible.
Participating in this kind of meeting is boring, just like a college student listening to a primary school student's class. Takahashi really wants to stretch his legs.
He secretly glanced at Fujiwara Miyuki. She was listening to the speech very seriously. Takahashi thought this lady was ridiculous.
The terrible thing is that today or tomorrow, there will be a trauma emergency surgery demonstration on the same stage.
It's so boring, like watching a football match.
The showdown between the Brazilian team and the Chinese team is a crushing, no-suspense showdown, which is very boring.
"Takahashi-kun, please be serious. The teacher asked you to come to the meeting, not to take a vacation."
Miyuki reminded Takahashi beside her.
Because he actually dozed off, folded his hands on his chest, and squinted his eyes slightly.
At this time, Director Tan wants to invite the patient Qiangzi to come out and demonstrate the functions of the limbs in person.
The magic started, and Takahashi cheered up.
He unscrewed the cap of the mineral water bottle and took a sip.
Because I was absent-minded, I almost choked on my drink.
