Chapter 179

Dean Fang’s face looked pale under the microscope.

“Zhou Yuan, slow down, do you finish dividing before I can see what this blood vessel looks like?”

Zhou Yuan: “Does it look good?”

Dean Fang:…

“You continue to divide…Are you sure you didn’t divide it wrong?” Dean Fang was a little worried.

He carefully inspected the three reticulated blood vessels and found that they were indeed consistent with Zhou Yuan’s judgment. During the inspection, Zhou Yuan had divided eight more…-…

I am three and you eight.

Dean Fang carefully distinguished the two without believing evil, and there was still no-error.

“How did you separate it…” Dean Fang couldn’t help being curious.

He is an expert outside his hands, the province is well-known, and he has a certain status in the country. Therefore, he knows that this thing is completely accumulated by experience…

He is a twenty-six year old guy, where does the experience come from? !

Zhou Yuan stared at the reticular blood vessels and said, “You may not believe it. When I touch them, they will scream. If it is a flexible artery, they will make a scream. If it is, they will scream. Very thick and very big veins, they will make a scream.”

Dean Fang: “You hurry up and stop talking.”

Zhou Yuan smiled.

“It’s finished, let’s start sewing, Dean Fang, please fix the silk thread of the same color.” Zhou Yuan said.

Dean Fang nodded silently, looked at the microscope, and carefully anastomosed the blood vessels.

Then, I saw Zhou Yuan’s stitches passed over and passed out again.

Dean Fang stared at these blood vessels, and an um ah ah sound came out of his brain.

“What am I thinking about…”

Dean Fang was dumbfounded.

“Zhou Yuan, you will be less talkative after surgery.”

I feel that there will be sounds in my brain after I suture the blood vessels.

Under the microscope, part of the blood vessels with spasm and the blood vessels with poor ejection at the proximal end were exposed.

Spastic blood vessels, the smooth muscles of the vascular wall contract strongly, and the lumen is narrowed. Even if it is sutured, the blood flow will be reduced a lot. The blood vessels in the eyes will even directly occlude the blood vessels, causing vascular embolism and other adverse reactions. Therefore, spasm reduction is necessary.

Zhou Yuan has already experienced this situation before

“The anastomosis time is too long, and the toes are cold.” Zhou Yuan said calmly.

“Director Wu, please help heating up, soak the gauze in warm salt water and cover it for a while.”

Wu Guohui quickly followed suit.(Read more @ wuxiax.com)

Sure enough, after tens of seconds, the vasospasm disappeared.

The poor ejection of blood from the proximal end of the blood vessel caused by the stenosis of the tube wall also disappeared.

Zhou Yuan quickly sutured, and soon the complicated network of blood vessels was connected.

“Rebuild bones.” Zhou Yuan said.

This step is relatively simple. Use Kirschner wire to connect the off-faced metacarpal bone and the toe bone, and then use a small splint for fixation.

The fixed parts are exposed except for the fingertips. This is to observe the blood circulation. Once the blood supply has problems, Zhou Yuan needs to adjust it at any time.

After all, Zhou Yuan found out the anastomosis of all blood vessels alone, and there is still uncertainty about whether it is feasible or not.

“Open blood circulation.” Zhou Yuan said.

Wu Guohui removed the vascular blocking forceps from his palm.

Under the thrust of the heart, the blood flow slowly enters the two toes, circulates in a circle, and returns to the vein.

After waiting for two full minutes, Zhou Yuan breathed a sigh of relief after seeing no abnormalities in the blood vessels.

However, this just means that the blood vessels are anastomosed very well, and the final effect depends on the patient’s recovery.

“Block the blood flow and start the nerve anastomosis.” Zhou Yuan said.

“Scalpel.”

Zhou Yuan did not hesitate to cut a few pieces of skin on his toe, centering on the place where the nerve needed to be sutured, and freed it from the proximal side of the nerve stump to another place where the nerve was connected.

This is to provide a good surgical field.

Compared with skin trauma, the surgical field to ensure the suture effect is obviously more important. It is normal to cut a few cuts.

“Intermittent stitching.” Zhou Yuan said.

The reason for intermittent sutures is simple, to avoid nerve distortion.

Continuous seaming sutures are not suitable for nerves, because once improper sutures appear, or the excitability of the nerves is too high, the entire nerve will be pulled by the sutures, causing distortion.

Once the nerve is twisted, the nerve will be damaged, and similarly, it will cause cauda equina-like neurological damage to the muscle.

The so-called cauda equina damage is a neurological syndrome in which peripheral nerves are paralyzed, disordered or dysfunctional due to external factors, and cannot regulate the motor sensation, pain, perception, temperature and other functions of the innervated area.

·········Ask for flowers···········

For example, aggravated nerve paralysis due to prolonged ischemia or secondary edema can lead to paraplegia. Some cauda equina damage is a man’s nightmare—it can cause dysfunction, sex, and dysfunction.

The damage of the cauda equina is a worldwide problem. No country has proposed an effective solution. There is no better coping strategy other than avoiding it as much as possible, and nerve distortion is also one of the factors that cause damage to the cauda equina.

Once the cauda equina is damaged, I am afraid that this time the regenerative finger surgery can only be declared a failure.

“Scalpel.”

Zhou Yuan dissociated the nerves of the severed face and toes under a microscope, and some of the nerves with the disease could only be removed.

………. …

There were also nerve defects in a few nerves. To put it simply, they were too short. Zhou Yuan could only flex the joints slightly, and gently pulled the nerves to extend them to overcome the nerve defects.

“It’s done. Dean Fang, please help fix your nerves.”

The head of the humanoid fixator Fang nodded silently, looked at the microscope, and began to anastomose the nerve ports.

There should be no tension in the suture between the nerves. Once there is tension, the tension will cause the sutured wound to burst and cause secondary injury.

Therefore, when Zhou Yuan stretched the nerve before, he extended it a little more millimeters to prevent accidents.

Fortunately, the suture of the nerve is also very smooth.

Dean Fang, who had been helping to fix him, looked horrified.

There are two villains in his mind arguing whether Zhou Yuan’s nerve suture technique is good or not.

Villain One: “Fuck, the docking is so accurate!”

Villain No. 2: “So accurate, so accurate!”

“Fuck! This diseased nerve Zhou Yuan chose to directly undergo nerve transplantation and performed a double-ended anastomosis on the nerve pulled out next to it!”

“Fuck, fuck! Anastomosis!”

Dean Fang was shocked in his heart.

Looking at the dedicated young man in front of him, Dean Fang had a feeling… he was witnessing history! The history of hand surgery!

He is watching the rise of the future leader and leading figure in the medical field! ! A.
