The news of Yang Ping's coming to the United States has been informed by Robert.

Woodhead and Griffin are full members of the WeChat group, so they naturally know the news.

Li Zehui and Massimo, who were applying to join the WeChat group, also received a notice from Robert, and they immediately put down their work and rushed to Mayo in Rochester, Minnesota.

Woodhead's Twin Cities Spine Surgery Center in Minnesota, which was closest to Mayo, was the first to arrive at Mayo.

Next up was Griffin, who works at MD Anderson Cancer Center in Houston, Texas, and is a surgical oncologist who specializes in all types of tumor surgery, as well as interventional tumors, chemotherapy, immunotherapy, biological therapy, and radiation therapy.

Griffin, who has always been silent in the group, actually speaks Chinese very fluently, he has passed the Chinese level 4 exam, this guy who only does not speak, he didn't expect to improve so quickly, Woodhead feels inferior.

Li Zehui of Cleveland Clinic in Ohio, Massimo of Johns Hopkins Hospital in Baltimore, Maryland, who were also not far behind the full members, arrived at Mayo in time.

The surgery was scheduled for the second day, and there was plenty of time, so after lunch, everyone met friends with tea in the hotel, held a small internal academic salon, and discussed some difficult cases.

Everyone had a good conversation and had an in-depth discussion on some cutting-edge medical technologies, of course, they most wanted to listen to Yang Ping's opinion, Yang Ping is everyone's mentor.

At the same time, Li Zehui and Massimo took the opportunity to formally submit the Chinese application for membership, and Robert conducted an interview with Li Zehui and Massimo on behalf of the organization, and if the application and interview were qualified, the two would have a three-month inspection period, during which they performed well, and the WeChat group voted again to decide whether to accept them as full members.

——

The next day, the surgery began as scheduled.

WeChat members also stayed at Mayo to observe the surgery, and it was difficult for them to have the opportunity to watch Yang Ping's surgery up close before they obtained the qualification for further education, so they cherished the opportunity.

It can be said that they cherish the opportunity to observe more than any other doctor.

Therefore, very early, under the leadership of a special person arranged by Johannathan, he took a good place in the classroom in the operating room.

Although Mayo's overall strength is the first in the United States, the strength of many individual specialties is not as good as that of other top hospitals.

For example, for the research, diagnosis and treatment of tumors, the MD Anderson Cancer Center is the first in the United States; For cardiology, Cleveland Clinic has long dominated the list; Needless to say, John's Hopkins is on par with Mayo's overall strength.

Johns Hopkins Hospital has created many firsts in the history of medicine, including the first heart bypass surgery, the first neonatal tetralogy of Fallot orthopedic surgery, the first complete sex reassignment surgery, and many more.

In clinical medicine, many of the procedures that are taken for granted today, such as CPR, kidney dialysis, and the use of sterile rubber gloves in surgical procedures, all began at Hopkins Hospital.

People came in one after another in the classroom, and soon the room was packed.

Mayo neurosurgeons were curious to find a few strangers sitting in the classroom.

The white-haired doctor and the muscleman doctor sat down next to the men, and the muscleman couldn't help but ask where these people were from, because it was definitely not Mayo.

The cow shook hands with these people one by one.

"Hello, Griffin, MD Anderson Cancer Center."

"Woodhead, Twin Cities Spine."

"Massimo, Johns Hopkins."

"Li Zehui, Cleveland Clinic."

None of these people are idle, but they are also neurosurgeons, why don't they know each other, it's impossible.

The muscular man of Sheniu had to inquire again, and the answer he got was -—— they were not neurosurgeons at all, but specialties such as oncology, spine, intervention, and heart.

"Are you interested in this surgery?" The muscular doctor asked curiously.

Griffin didn't bother to answer this boring question, and he didn't have any interest in chatting with the muscleman, Griffin now felt that he was not a doctor of the same grade as the muscleman, after all, he would soon join the mysterious world's top medical club.

Woodhead nodded: "The Chinese doctor in charge of the surgery is our mentor, so we sit here and learn." ”

Their mentors?

The muscular man couldn't turn around at all, and these bull-level figures in different majors all took Yang Ping as their mentor and claimed to be Yang Ping's students.

Whoever you change to be can't turn a corner for a while.

At this time, the muscular man's curiosity immediately turned into an inexplicable awe.

"Who are they?"

The white-haired doctor asked the muscular man.

The muscular man's tone was a little unconfident: "They are all students of Chinese doctors. ”

——

The surgery officially begins, and the entire operation will be performed under a microscope.

It's not just talking, it's really about taking off an eyeball and entering through the eye socket.

The approach to the surgery is a bit strange, the first step is to make a small incision on the lateral canthus of the eye, and then a small window is made in the bone wall.

Then, the separation and removal of the eyeball begins, and the conjunctiva is incised in a circular manner along the limbus with a sharp scalpel, followed by the separation of the conjunctiva and subconjunctival tissue downward, all the way below the equator.

The connection between the eyeball and the eye socket consists of blood vessels, nerves and muscles, which are structures that must be preserved, and blood vessels and muscles can be severed.

Because the blood vessels can be anastomosed after they are cut, and the same is true for the muscles.

However, the nerve is different, once the nerve is severed, the anostomosis cannot be repaired by repairing the broken end.

Once the nerve is severed, the distal nerve will be directly invalidated, and the nerve fibers inside will eventually dissolve and disappear, leaving only an empty tube, and the proximal nerve will grow into the distal end like a vine sprouting, and continue along the canal left by the old nerve, and finally grow to the end, that is, the innervated part.

There is a problem in this, in the process of growing these nerves, some will make mistakes, and some will be lazy, and they will stop growing when they reach a certain distance, so the nerves that eventually grow to the destination will definitely decrease, and if the distance that needs to grow is too far, it is likely that all the nerve fibers will not grow in the end.

Therefore, trauma orthopedic surgeons are not afraid of blood vessels being cut off, as long as the blood vessels are cut and the bleeding is stopped in time, there will be no sequelae after the operation to anastomosis the blood vessels.

They are most afraid of nerve rupture, and if the nerve rupture is located relatively high, that is, it ruptures at a distance from the end, it will definitely leave a serious disability after the operation.

There is a nerve in the wrist called the median nerve, which is about the middle of the wrist, and the position is relatively superficial.

Eye transplantation is currently in the experimental stage, and there are only a few clinical cases in clinical practice, and the effect is not satisfactory, and the reason for the poor effect is here.

The operation continued, and the four rectus muscles were separated, and a figure 8 suture was used at the insertion point of the rectus muscle, and then the rectus muscle was cut, leaving the tendon stump of about 0.5mm in the medial rectus muscle, and the silk suture was used to stretch the eyeball.

Then, starting from the upper medial part of the optic nerve, continue to separate the optic nerve deeply, obtain a generous length, and use the silk thread sutured at the stump of the rectus muscle in the eye as the traction line, gently pull the eyeball to see how far it can be removed.

Finally, and the most difficult step, we begin to separate the branches of the ophthalmic arteries one by one, protect them from damage, and then follow them to the main trunk of their distribution, the ophthalmic artery, where it is cut and marked with a small non-damage line.

This step of the operation is coordinated by the operation of the eye socket and the window on the outside of the eye socket to complete the separation and severance of the blood vessels.

Mayo's ophthalmologists have been watching the operation from the stage, and they are also very new to this kind of surgery, but just observing the way Yang Ping deals with the ophthalmic artery, the ophthalmologist has to admit that this Chinese doctor is a world-class ophthalmologist.

The Chinese doctor is more familiar with the anatomy of the eye than any Mayo ophthalmologist, and not a single drop of blood came out of the entire procedure. Moreover, the level of operation under the microscope is extremely high, and the entire operation under the operating microscope is completely suspended on both sides, without relying on the support of the operating table.

"Protect your eyeballs with ice gauze!"

Yang Ping instructed the assistant, and at this time the assistant was not Johannesen, but an ophthalmologist.

The ophthalmologist carefully wraps the eyeball with sterile ice saline gauze.

Yang Ping found that every piece of Mayo's gauze has a QR code, and the channel can scan the QR code to track and trace the source of the gauze, and the Americans still have a set of management.

In the teaching room at this time.

The live video has always been the operation in the field, and there is a small video with a larger viewfinder in the upper right corner of the high-definition screen, which allows you to see the entire upper limbs of the main surgeon and assistant.

The entire micromanipulation of the main knife is both upper limbs suspended?

How can the speed of the suspended operation be so fast?

Every doctor is admired by this kind of suspended operation, and the level of operation under the microscope is the lifelong pursuit of any neurosurgeon, so to speak, without a certain ability to operate under the microscope, he cannot become a neurosurgeon at all.

If you ask another doctor to do this, you must support your elbows on the operating table on both sides, so as to ensure the stability of your hands and keep the operation under the microscope from shaking.

Suspended operation, a short time is OK, long time is simply difficult to maintain.

Moreover, the suspension operation is generally slow, and it cannot be fast and flexible.

But Yang Ping is now in the air, and the next operation is still in the air.

This is not that Yang Ping deliberately shows off his skills and pretends to be forced, for him, the microscopic operation under the suspension is very stable, so why bother to prop his elbows on the operating table, and do more.

"All of his operations just now were in the air?" The white-haired doctor was surprised.

The muscular man disagreed: "The current operations are all rough operations, and the impact is not great, and it is impossible to wait for the delicate operation into the skull to hang your arms in the air for a long time." ”

"Just separating the ophthalmic artery from the optic nerve is a delicate operation, right? Especially the separation of the ophthalmic arteries and branches? "The white-haired doctor just saw very clearly.

Members of the WeChat group sat together and whispered about the surgery in Chinese.

"The professor is getting better and better, and the operation of his hands in the air is so stable."

"yes, the support only slows him down and makes him feel less flexible."
