"The US Consulate's surgery will be postponed until noon tomorrow?"

Yan Feifan told the baby's thumb transplant surgery and his thoughts to the big belly man in the relevant department on the phone.

The other party pondered on the phone for a while and replied: "Doctor Yan, yes, I will notify the US side to coordinate."

This reply made Yan Feifan feel relieved.

He was really worried that the other party would put national interests and diplomatic relations first and would reject his arrangements.

If this happens, Yan Feifan doesn’t know whether he should persist or persist.

"Thank you for your understanding."

Yan Feifan said politely, and asked with concern: "Well, temporarily postponing the operation will not trigger the other party's protests and affect the relationship between the two parties, right?"

The big-bellied man chuckled during the call and said, "No, the era of what they say is what is over long ago."

"In other words, the most popular sentence at the moment, we Chinese don't like their tricks."

After pausing for a moment, the big belly man laughed again: "The most important thing is that in the matter of surgery, they have the requirements for us, we have absolute initiative, you are stuck in their necks..."

After successfully solving the operation arrangement at night, Yan Feifan immediately began to prepare for the first baby finger transplant surgery in his life.

If you want to do things well, you must first sharpen your tools!

The development of modern medicine, especially surgical medicine, is closely related to the research and development and improvement of surgical equipment and devices.

Before surgical microscopy is applied to clinical surgery, surgeons are unable to suture human tissues such as blood vessels and nerves with a diameter of less than two or three millimeters.

With the surgical microscope, microsurgery was discovered rapidly, greatly improving the success rate of fine surgeries such as limb transplantation and organ transplantation.

However, due to the accuracy of microsurgery instruments, such as the standard needle diameter of microsurgery needles is 0.1 mm, it is difficult for surgeons to suture human tissues with diameters less than 0.5 mm.

There are also microsurgery instruments with higher accuracy.

The smallest standard surgical needle in the world today has a needle diameter of only 0.03 mm and a needle length of 0.8 mm.

The matching suture thread is even more difficult to see with the naked eye, with a diameter of only 0.012 mm.

This extremely fine surgical needle allows suture surgery for blood vessels, lymphatic vessels and nerves below 0.5 mm diameter, making finger transplant surgery possible for babies.

However, due to the surgeon's operating accuracy limit, it is difficult for a surgeon to control such extremely fine surgical needles.

Such super microsurgery requires extremely high operating stability and operating accuracy of surgeons.

This cannot be achieved by hard work. It can be said that it depends on a person's talent limit.

If you count Dr. Qin Ying before he was injured, as Yan Feifan knows, there are now four surgeons across the country who can handle this extremely fine microsurgery needle for super microsurgery.

Yan Feifan's surgical operation accuracy and stability have always been his proud expertise.

This is also one of the main reasons why he can do plastic surgery and repair surgery so perfectly and can do anything else.

During Tang Zheng's plastic surgery and repair surgery, Yan Feifan finely sutured the muscle bundles, blood vessels and nervous system of the autologous transplant. The minimum diameter of the sutured blood vessels and nerves has reached about 0.4 mm.

At that time, the minimum non-standard microsurgical needle used by Yan Feifan was 0.05 mm in diameter.

For infants' finger transplantation, the blood vessels and nerves that need suturing, with a minimum diameter of 0.3 mm or even 0.2 mm.

This is definitely a challenge for Yan Feifan.

He thought to himself that with his own technical level and experience, he could deal with it.

However, some practice and familiarity before the formal surgery begins is necessary and necessary

Yan Feifan sent Pan Jichuan, Yu Beihua, Zhu Jian and other students away, asking them to go to the trauma surgery department with Teacher Qin Ying.

Before the operation, Yan Feifan needed to use the surgical practice room of trauma surgery for exercises.

Yan Feifan's Medical Research Office is too small and does not have his own practice room, which makes him feel more and more inconvenient.

But the hospital's office was quite nervous, and in this case, he could only borrow the venues of other departments.

Fortunately, his face is big enough and he can always meet all his requests.

After leaving the office door, Yan Feifan quickly took the surgical instrument box held in Teacher Qin Ying's hand.

This box is like a small cuboid hand-carrying file box, which is forty centimeters long and thirty centimeters high. It is made of metal, frosted gray, and the front is marked with several island texts.

This is a set of extremely fine microsurgical needles with diameters of 0.03 and a matching super microsurgical instrument.

Yan Feifan held it in his hand and weighed it, weighing about eight pounds.

He asked curiously: "Teacher, how much does such a set of surgical instruments cost?"

"You guess first!" Qin Ying, who was in a good mood, was rarely kept in a silence.

Yan Feifan doesn’t know much about surgical instruments.

He just knew that a set of standard microsurgery instruments with very good quality ranged from tens of thousands to hundreds of thousands.

"Four or five hundred thousand?" Yan Feifan estimated a number.

Qin Ying didn't continue to suck her appetite and replied directly: "One,420,000, it's still a discount."

"It's so expensive?" Yan Feifan was a little surprised.

Qin Ying sighed lightly: "The island country has quite an advantage in special steel and precision processing."

"There are only the very fine microsurgery needles of this specification, and this one is naturally expensive."

After pausing, Qin Ying continued: "Of course, it's mainly because the medical market is too small."

"You can sell 10 or 20 units in a year in the whole world? Companies from other countries are not worth investing a lot of money in research and development."

This made Yan Feifan think of something.

It is said that it is the small steel ball of the tap water refill before, which cannot be produced in China and is subject to foreign countries.

Under the strong appeal of patriotic netizens, well-known domestic steel mills invested R&D funds to produce a furnace of steel.

It is said that the furnace of steel can meet the needs of the production of small steel balls in the world for many years.

As Yan Feifan knows, some high-end and sophisticated sub-sectors have small markets and high R&D and supporting investment. Many of these companies are unique in the world.

Yan Feifan remembered something again and asked, "Teacher, Sister Xiaodan broke up with that guy, right?"

Qin Ying nodded and said a little embarrassedly: "That guy agreed to five million..."

Yan Feifan took the speech and said, "Teacher, don't take it to heart, the other party will break his word."

"As an experimental operation, there will definitely be shortcomings, let alone such a critical part. It is reasonable for the guy to refuse to pay if he fails to meet his ideal request."

Yan Feifan chuckled again and said, "He also provided at least one million in preliminary research and development funds, and we are not losing at all."

Qin Ying exhaled gently and said, "Feifan, take me as a warning. If anything similar happens in the future, it must be implemented in a paper agreement so as not to refuse to admit the account afterwards."

Yan Feifan nodded heavily...

A few minutes later, the two came to a surgical practice room in the trauma surgery department and started preparations.

This time, Yan Feifan was not wearing a surgical mask, but a fully enclosed surgical mask.

It looks a bit like an astronaut's hood and has its own respiratory and circulation system.

This is worn during surgery for infectious patients.

Yan Feifan wore such a surgical cover. Because his extremely fine microsurgery needles and surgical sutures were too small and light, his breathing was heavier, and he might blow away.

If you really blow it away, you won’t have to do anything else for this operation. All the surgical members have to hold magnifying glasses and lie on the ground to look for surgical needles.

After getting ready, Yan Feifan, who was fully armed, stood in front of the microsurgery lens and adjusted his breathing and heartbeat.

He needs to keep his breathing and heartbeat stable and not interfere with the operation of his hands.

This level of surgery is a real difference, but it is a huge loss. If the fingers holding the needle move slightly larger, it is likely that they will run out of the microscope's surgical field.

After more than a dozen exhalation and inhalation, Yan Feifan signaled Teacher Qin with his eyes that the practice could begin...
Chapter completed!
