Back in 2002 as a doctor

The needle vibrates slightly in the blood vessel as if it has no strength.

"Stop!" Dr. Smith yelled to stop immediately without waiting for a tube of contrast medium to be injected.

Perhaps fortunately, perhaps unfortunately, the sewing needle did not cut through the bronchial artery, but landed on the adventitia of the outer layer of the bronchial artery.

"This..." Dr. Smith almost cried.

The difficulty of the operation itself is extremely high, and he has less than 1% certainty.

But as soon as the radiography was performed, the sewing needle advanced a little bit... Dr. Smith was crying, and he really didn't want to do it any more.

The difficulty of the operation has increased again. It seems that the slight movement of the sewing needle will cut the bronchial artery.

Dr. Miyamoto was also stunned.

Originally, the difficulty of the previous surgery had already dissuaded everyone, but now that it happened again, how should the surgery be done?

He subconsciously took half a step back, to save Dr. Smith from taking the responsibility on himself.

The surgical team standing in the operating room was also dumbfounded after seeing the images.

Chu Yuntian almost covered his eyes with his hands.

I really can't bear to watch it any longer.

Surgery could still be done before, but after the radiography, the sewing needle almost stuck on the bronchial artery. Although it was not broken, it was just at the position where it was about to be broken.

Well, surgery is impossible, and the problem that could be solved by cutting a lobe of the lung has now entered a dead end and become an unsolvable problem.

"What's next?" Dr. Miyamoto asked in a low voice seeing that Smith was already dumbfounded.

Smith stared blankly at the video, what else could he do next, try it... try it...

The operator Zhou Congwen and Dr. Smith twirled their right thumb and index finger at the same time, but the microguide wire did not move. Instead, they lingered before the barrier, feeling the power of the blood flow, and looking for the most suitable angle.

If there is a slight error, maybe the micro-guide wire touches the edge of the sewing needle, and if you tap it lightly, the tip of the sewing needle will draw a hole in the bronchial artery, causing massive bleeding.

So both Zhou Congwen and Dr. Smith are looking for the feel before sending the guide wire.

Zhou Congwen took a deep breath, crossed his left and right hands, fixed the micro-guide wire with his left hand, and gently twisted it with his right hand to send the micro-guide wire in.

The needle eye of the sewing needle is thicker than the micro-guide wire, about 1mm, and there should be enough space for the [-]-point guide wire to go in.

However, there is thrombus agglutination in the eye of the needle and changes in hemodynamics, so the problem cannot be solved directly.

Before twisting the micro-guide wire in front of the needle, Zhou Congwen had already felt some power transmission, and he had an assessment of the complex dynamic interference in his heart.

It's just that this kind of evaluation is a feeling in a state of flow, and there is no way to quantify it with existing technology. Even Zhou Congwen himself has to resign himself to fate.

Dr. Smith squinted at the screen, and his hand began to move the microguide wire slightly forward.

In the previous practice and surgery, Dr. Smith was able to penetrate almost [-]% of the double-layer stent mesh with a [-]-point guide wire.

This is also his confidence in operating on old Morgan.

However, the current operation is completely different from what was seen on the preoperative images.

The blood flow impact is more complicated. Although the force is very small, it needs to penetrate the needle hole of less than one millimeter... The difficulty rises geometrically.

No way, Dr. Smith bit the bullet and wanted to try it once.

He didn't think he could succeed the first time either. Failure is a very normal thing. He just hoped that the strength of the guide wire would not be too strong.

The micro-guide wire moved forward, and the closer it was to the needle eye, the greater the disturbance of the blood flow, and the sweat on Dr. Smith's body instantly burst out.

Although he couldn't see it, he could sense the constant trembling of the front end of the guide wire from the force transmitted back from the micro guide wire.

This……

Can't wear it at all!

Dr. Smith gave up an effort before he even tried it.

Zhou Congwen was as steady as an old dog.

In the past, his hands seemed to be made of iron. No matter what situation he encountered during surgery, he never shook.

But standing in the operating room of the system, standing in front of the simulator, Zhou Congwen's hands were trembling invisibly.

Muscles and fascia are mobilized, and every muscle fiber controls the micro-guide wire under the control of heart flow to fight against hemodynamic interference.

Even in the narrow and constricted pulmonary artery, even with complex hemodynamic disturbances, Zhou Congwen still pushed steadily.

The micro guide wire passed through the eye of the needle steadily, and it was done!

Become!

Zhou Congwen himself was quite satisfied with this operation, and even felt a little complacent in his heart.

This is a challenge to one's own abilities.

Fight and win!

Zhou Congwen flicked his wrist, ready to use the hook to pull the edge of the needle eye.

But at this moment, the sewing needle moved slightly, and the alarm sounded loudly in the operating room of the system.

Surgery, failed.

Chapter 1077 Surgery in different time and space

Zhou Congwen's pupils shrank, and a murderous aura burst out through the lead clothing.

What the hell, I thought it was done for a second, but before the hook hooked the eye of the needle, the needle tip just made a slight movement and cut the bronchial artery, resulting in the failure of the operation.

Although the procedures of the two operations in different time and space are different, the outcome is the same.

failure!

With such difficulty, both Zhou Congwen and Dr. Smith found it quite difficult, and even Dr. Smith was directly dismissed from trying.

Zhou Congwen and Dr. Smith took a deep breath to calm themselves down.

After one attempt, the two had a deeper judgment on the difficulty of the operation.

Zhou Congwen knew very well that this operation was beyond his ability, if there was Shen Lang... No, that guy's level is not enough.

If there is Liu Wuyan... no, Liu Wuyan doesn't cooperate well with him.

Only by cooperating with the boss can the operation be completed.

For example, the boss.

Only the boss.

I used to think that the difficulty of the operation lies in "threading the needle". If I can put the [-] guide wire into the needle eye of the sewing needle, pull it gently with the hook loop, and pull the sewing needle out, the operation will be considered a success. .

but!

The needle tip of the sewing needle is too close to the bronchial artery, and a slight movement will cut the bronchial artery.

Unless the sewing needle is pulled straight up and down, there is no chance at all.

Zhou Congwen didn't start the stage directly, he was in a hurry, but if he was in a hurry and didn't make a summary, the time would be wasted instead.

Sometimes, it's faster to go slow.

Carefully pondering and analyzing the reasons for the failure of the last operation, Zhou Congwen felt bitter in his mouth.

Straight up and down?

That means that the difficulty of surgery has skyrocketed again.

The operation just now was already the upper limit of his ability.

After returning from rebirth, after a year of training, Zhou Congwen's overall level is close to his peak level in his previous life.

That's all.

Zhou Congwen knew that it was basically impossible for him to successfully complete the operation.

Even with the help of the boss, it seems that it will not work.

Assistants are indeed useful, and can even play a role in setting the world at certain times.But no matter how strong it is, it is subject to the level of the operator, and it will never be improved without reason.

The level that the boss can achieve in this kind of fine operation should be similar to his own. Zhou Congwen has predicted this point, which is a very objective judgment.

After all, he is already an octogenarian, and the boss can guarantee 10 minutes of peak operation, which is already a super-level performance.

Whether it is the boss's hands-on operation or his own operation, the outcome should be similar.

After a short thought, Zhou Congwen decided that the operation had reached a dead end.I can't do it myself at all...

This is an impossible task.

Even though he thought so, Zhou Congwen felt that there must be something he didn't expect when the system issued tasks and opened the system operating room without hesitation to consume a lot of energy.

Come again!

Try to apply force straight up and down, and try not to let the force of the guidewire hook loop deviate the needle tip.

Another attempt to start.

In the operating room of Mayo Clinic, Dr. Smith was covered with sweat under his lead suit. The operation was more difficult than he had imagined.

"Dr. Smith, what if..." Although Miyamoto was an assistant, he also felt the real difficulty of the operation.

Seeing Dr. Smith looking at the screen, he suggested in a low voice, "If it's too difficult, just give up."

"Impossible!" said Dr. Smith.

"If the operation fails, it's better to give up the operation instead of emergency thoracotomy."

Dr. Smith knew it was the right thing to do.

Everyone will have a relatively good result, but I am the only loser.

In the previous consultation, almost all experts agreed to either conservative observation or surgical resection of the right upper lobe.

The old Morgan insisted on interventional treatment, and he was the only one who agreed.Even Dr. Miyamoto who was beside him was forced to come.

If you declare failure without giving it a try, you will become the laughing stock of the academic world!

Dr. Smith repeatedly weighed between the two, and suddenly gritted his teeth, "Try again, I can already vaguely feel the disturbance of blood flow."

Vaguely?

Dr. Miyamoto sneered in his heart.

Americans are like this, but vaguely that is not enough.

Dr. Miyamoto highly doubts that Dr. Huang can perceive hemodynamic disturbance, even his student Zhou Congwen can perceive it.

This is the most profound "skill" of interventional surgery, or inaccurately speaking, it is a kind of hand feeling, which belongs to the existence of another plane.

"Again!"

Zhou Congwen and Dr. Smith made a decision.

The patient was on the operating table, and the needle was stuck in the right upper lobe artery. How could it be done without taking it out!

The operation begins again.

The simulated human test body in front of Zhou Congwen has been replaced with a new one, which has been re-sterilized, covered with sheets, and placed with tubes.

The microcatheter walked, followed by the microguide wire, and came to the sewing needle again very smoothly.

Re-choosing the location, Zhou Congwen made minor adjustments after the previous failure experience.

A point-[-] guide wire with a small hook at the front protrudes from the microcatheter, like Dongfeng standing on a launch pad.

The choice of position is also very particular. Zhou Congwen's self-confidence has returned. He believes that this time there is a slight possibility of success.

Dr. Smith doesn't have Zhou Congwen's confidence.

Originally, he thought it was possible, but a radiography shattered his confusion.Dr. Miyamoto's words planted a thorn in his heart, as if a sewing needle teleported into Dr. Smith's heart inexplicably.

The micro-guidewire moves forward again.

In the operating room of the Mayo Clinic, Dr. Smith concentrated on twisting the micro guide wire, trying to feel the interference of various forces from the guide wire, and strive for a success.

But the closer the microguidewire gets to the eye of the needle, the more pressure Dr. Smith feels.

Not just the stress of complex hemodynamics, but the stress of reality.

After the radiography, Dr. Smith knew that the needle tip of the sewing needle had landed on the adventitia of the bronchial artery. He guessed that perhaps just a slight movement, a "misuse" operation, the operation would fail.
