On Saturday, at nine o'clock in the morning, the meeting started on time.

The large conference room of Sanbo Hotel was full, and the front row was also full of guests.

As of 9 o'clock, the number of delegates exceeded 2,000, and if 1,000 people came to this kind of hospital's unique learning technique, it would be very successful, and now more than 2,000 doctors have registered at the meeting.

The large conference room of Sanbo Hotel can accommodate up to 1,000 people, and it can only be done with temporary stools.

According to the plan, in addition to the main venue, six sub-venues were opened, and the sub-venues used the large screen to watch the speeches of the guests, and the Q&A session with the guests could be completed by using the video call function.

The mobile company cooperated with Sanbo Hospital to help Sanbo build a video system for the entire venue with 5G technology, and they also took the opportunity to promote 5G.

After Director Tan made a speech at the opening ceremony, he introduced the guests.

He began to show everyone the current situation of the Department of Microtrauma and Orthopedics of Sanbo Hospital, especially the case of five-stage replantation as a signboard.

For this operation, the video data is complete and the most convincing, and the surgical patient Xiao Guoqiang took the initiative to apply and stood on the podium to demonstrate the function of his limbs.

Director Tan's speech will be in English, and all other guests will be in English, positioning it as an international conference, and it will be impossible to speak without English.

The team led by Tang Fei is responsible for the on-site translation, she studied in a bilingual school in Chinese and English in primary and secondary school, so she speaks and listens very well in English, and she is a doctor, so her translation is no worse than that of a professional translator, and her translation of medical terminology will be more accurate.

Translator, in order to make the participating doctors understand, because the vast majority of doctors do not have the ability to listen and speak in English, even if they have passed level 4 and 6 when they are studying, they are all dumb English, and they can do questions, but they can't really listen and speak.

Qiangzi was in the backstage of the conference room, a little nervous, and his girlfriend comforted him: "It's okay, relax, according to the doctor's explanation, show them the truth, just in front of Director Han and Dr. Yang." ”

Dr. Che, who is in charge of Hadron rehabilitation, instructed the actions that needed to be demonstrated again, and Hadron followed alongside carefully.

This five-stage replantation was very sensational at the time, and almost all trauma orthopedic surgeons across the country knew that everyone was amazed by the superb technology of Sanbo Hospital, but at the same time, they did not have any hope for the function of the replanted limb.

Everyone thinks that Sanbo Hospital did this operation completely to win eyeballs, and maybe after a while, the limb will be amputated because it has no function and becomes a burden.

Whether it has a function or not, whether there is an amputation in the end, everyone wants to know the result, and many doctors come to this.

Director Tan originally planned to shoot a video to show the postoperative function, but after Hadron knew the situation, he took the initiative to ask for a demonstration at the venue in person.

The replanted limb had no problems with vascularization, the muscles and tendons had healed, and the most challenging thing was nerve repair.

According to the electromyography test, the nerve has grown to the wrist, which is in line with the average growth progress of one millimeter a day.

Unlike other tissues, which are healed, nerve ruptures are dissolved, and nerve breaks down, the distal section is completely wasted, and the nerve fibers disintegrate, leaving an empty shell duct.

Nerve repair: The nerve near the end of the break grows through the canal left at the distal end and grows all the way to the end of the limb in order to function well.

The higher the position of the nerve break, that is, the farther away from the terminal, the less likely it is to grow over, those tubes are big tubes and small tubes, and there are many nerve fibers that can't find the tube, and without the tube, it won't be long, just like a train can't move without tracks.

The nerves of the limbs are divided into motor nerves and sensory nerves, the two have different functions, one is responsible for the movement of muscles, the other is responsible for the sensation of the skin, many nerves grow at the broken end, they will drill the wrong tube, the motor nerve drills the tube of the sensory nerve, and the sensory nerve drills the tube of the motor nerve.

In this way, many factors lead to the recovery of peripheral nerves, especially the recovery of high nerve damage, which is very ineffective and is a worldwide problem.

The nerves of the hadron reach the wrist, and the muscles of the forearm gain innervation.

The dorsal extension and flexion of the wrist joint are very good, and the flexion and straightening of the five fingers are also very good, but the palms 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 have not yet grown and are not connected to the muscles of the hand.

Judging by the current growth trend, the last five centimeters should be long.

Hadron demonstrates elbow and wrist resistance with dumbbells, and five fingers to hold the ball.

If you wait for another two months, it is estimated that you can easily write and use chopsticks, but the intrinsic muscles of the hand have not yet obtained innervation, and it is difficult to hold a pen and chopsticks without the palm-to-palm movement of the thumb.

Five-stage replantation, with half a year to obtain such an effect, has been very successful.

Yoko was very accurate in judging the traffic situation in G City, and at about half past eight, she sent Miyuki Fujiwara and Fumiya Takahashi to Sanbo Hospital on time.

Miyuki Fujiwara and Fumiya Takahashi naturally became the focus of the meeting.

Miyuki Fujiwara is the champion of the Victoria's Secret show, and the doctor in the world is the only one; Fumiya Takahashi, as a doctor at the University of Tokyo Hospital, became famous very early, and is often active in various large-scale international conferences, and is a leading figure in trauma surgery.

For example, at the North American Annual Meeting of Trauma Surgery, he was able to be invited as a guest and attend the first row, and it is estimated that only his teacher Fujiwara Masao and him can have this status in Asia.

After listening to Director Tan's introduction, Takahashi touched his chin, and the five-stage replantation of the upper limbs was impossible if he wanted to have a good function, Takahashi Fumiya had a sober judgment on this.

It's just a gimmick of the meeting.,There's really nothing to come up with.,Only take the amputated limb that I'm good at and replant.,As for the function.,Wait and see.。

From the beginning to the end, Takahashi was reluctant to participate in this small meeting, and there was a lot of resistance, and behind the etiquette that seemed very sincere every time, there was arrogance and prejudice.

He didn't even take the initiative to talk to the Korean doctor next to him, and when people asked a question or two, he also replied bluntly, hoping that the meeting would end soon, and he was here to complete his homework for the teacher.

The video of the amputated limb replantation operation is shocking, and the speed and rhythm of the operation are incredible, but Takahashi thinks that the video is suspected of editing, just watch it.

As a leading figure in trauma surgery, he knows very well what the difficulties of this five-stage replantation are.

If the nerve can grow smoothly, it needs to cross five fractures, which requires a very high degree of nerve suturing technique, which is theoretically feasible and no one can do it in practice.

If you can't do it yourself, who else can?

Takahashi decided that if he had the opportunity, he would personally check the patient's function, but I didn't know if he would be given this opportunity.

I had no interest in the meeting, but when I thought about it, I suddenly became interested, just like the audience insisted on exposing the magician's tricks.

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 the excellent algorithm of the computer, which can make trauma patients become transparent people on the operating table.

This technology is currently unique in the world, making hemostasis on the operating table almost impossible to fail.

Fujiwara's next goal is to overcome the repair of peripheral nerve damage, also using infrared technology, using a nerve fiber clearing agent, so that the motor nerve appears red in the infrared, and the sensory nerve appears blue, and then these images are integrated with the camera system, and finally the image of the nerve fiber captured on the screen is divided into clear blue and red.

In this way, the anastomosis of blue to blue, red to red, and the nerve anastomosis will not be mismatched, and the effect of nerve recovery will be multiplied.

There are two factors that contribute to poor nerve recovery: first, the loss of nerve fibers due to the erroneous growth of the nerve; Second, the nerve growth rate is too slow, resulting in degeneration of the target organ.

At present, the University of Tokyo Hospital has solved the first factor, and the second problem is in an experimental state, although it is not mature, but it can be broken through soon, and if the two problems are solved, they will overcome a world problem.

The second problem is that the speed of nerve growth is too slow, the motor nerve innervates the muscle, sometimes, the nerve grows by chance, but the muscle is denatured and fibrotic because there is no innervation for a long time, the muscle is not a muscle, it becomes fibrous tissue, even if it is innervated, it cannot complete the function of contraction.

To break through the second problem, either speed up the growth rate of nerves, or let the muscles remain in a normal state for a long time and cannot be fibrosized.

Takahashi is now working on this topic, so that the nerve can grow faster and integrate with its target organs as soon as possible.

It's boring to participate in this kind of meeting, like a college student listening to an elementary school student's class, and Takahashi really wants to stretch out.

He stole a glance at Miyuki Fujiwara, who was listening to the speech very seriously, and Takahashi thought the young lady was ridiculous.

What's worse is that today or tomorrow, there will be a demonstration of trauma emergency surgery on the same stage.

It's so boring, it's like watching a football game.

The matchup between the Brazilian team and the Chinese team, a crushing and suspenseless matchup, will be very boring.

"Takahashi-kun, please be serious, the teacher asked you to come to the meeting, not a vacation."

Miyuki reminded Takahashi beside her.

Because he actually dozed off, clasped his hands in front of his chest, and squinted slightly.

At this time, Director Tan wanted to invite the patient's hadron to personally demonstrate the function of the limb.

The magic began, and Takahashi cheered up.

He unscrewed the lid of the mineral water bottle and took a sip.

Because of absent-mindedness, I almost choked on drinking water.
