As the operation began, several doctors fell silent.

The three doctors in the Department of Gastroenterology paid attention to Zhang Tianyang's operation while observing the progress of the gastroscope on the screen.

Qiu Ming and Nurse Xiao Xu are old people who have worked together twice, and with the experience of the first two times, they are still quite calm.

But the chubby Long Zhizhi and the cold Tang Zhuzhi are the first time to witness Zhang Tianyang's operation.

"Teacher Zhang's operation is very skilled!"

The chubby dragon chief was secretly surprised in his heart, and his eyes involuntarily wandered on Zhang Tianyang's face.

Really, really young......

And they're really interns!

The information that the director of the Department of Gastroenterology had revealed to him before he came came was repeated in his mind.

"Obviously, it hasn't been long since I got out of the clinic, and I haven't rotated our gastroenterology department......"

His task was to keep notes, and he didn't have any hope that he could learn much, and his mind continued to diverge.

Suddenly, he suddenly thought of a possibility.

"Could it be...... It's a snatch!"

......

The cold Tang Zhuzhi frequently stayed on the screen at first, and when he waited later, he just stared at Zhang Tianyang's hands.

After staring at it for a while, his eyes narrowed slightly.

It's so stable.

It's basically the wrist moving.

The forearm also moves occasionally.

But above the upper arm, it has been maintained in the same position.

Such a posture requires not only great control, but also excellent physical strength.

The cold Tang Zhuzhi stared at it for a while, and couldn't help but be distracted.

Zhang Tianyang's talent is really suitable for surgery.

I don't know which surgeon or professor will be able to take him under the door in the end.

......

"Okay, Xiao Xu is ready to deflate, Senior Brother Qiu is ready. ”

Zhang Tianyang's cold voice called the two people back in a trance.

Only then did they realize that just after they had just lost their minds, the qi in the esophageal part of the three-lumen and two-cyst tube had already been unconsciously released, and the mirror had already walked to the bottom of the esophagus.

Further on, there is the cardia that has been stretched out by one size.

A rubber tube stretched out in front of the camera, attached to a balloon-like object, stuck in the hole.

Traces of blood slowly seeped out from around the mouth.

The expressions of the chubby Long Zhizhi and the cold Tang Zhuzhi instantly became serious.

The three-lumen two-capsule tube is not long, but when it is used on a patient, it is always pulled out of their nose, pulled tightly to their feet, and then hung on the infusion stand with a heavy object.

The degree of elongation represents the pressure of the entire three-lumen two-capsule tube.

However, even under such pressure, blood can still seep out of the field of vision.

Well, the blood pressure inside the stomach ......

As soon as the three-chamber and two-capsule tubes are loosened and the obstacles blocking the mouth are removed, will the blood inside be sprayed all over the face in an instant?

There was no trace of a smile on the fat dragon's face, and the fat on his mouth trembled twice.

A faint sweat oozed from his forehead.

He subconsciously took a step back, and then suddenly remembered that he was not the operator.

Looking left and right, the chubby dragon master found his expression management and quietly took another step forward.

The cold Tang seemed to be relatively calm.

He only turned his slightly inclined body and quietly hid his slightly trembling fingertips.

"Nurse Xiao Xu, I'll trouble you to deflate quickly. ”

"Senior Brother Qiu, the pipe will be handed over to you, remember to cover it up a little, don't let the blood spurt everywhere. ”

"Senior Brother Long, is there a mask here? ”

The tasks were all assigned, and Zhang Tianyang did not forget the task of his teaching, and pointed out a point on the screen.

"Senior Brother Tang, do you remember the blood flow we just analyzed?

Later, I will send the gastroscope from this position, and from this point, I will control the depth of entry at this point. ”

Zhang Tianyang tapped on the scale of the gastroscope.

"This way, the mirror can just reach point E that we just discussed. If our prediction is correct, there may be three kinds of blood flow, do you remember, senior brother?"

"Yes. ”

The cold Tang Zhizhi was concise and to the point, but his mind was spinning rapidly.

Soon, he sketched out several models that Zhang Tianyang had just built for him.

"I'll try to identify it later. ”

Zhang Tianyang paused and took a deep breath.

"Alright, let's prepare. ”

Nurse Xiao Xu and Senior Brother Qiu Ming tensed up instantly.

Zhang Tianyang's eyes also sharpened.

"3.2.1 begins!"

With Zhang Tianyang's order, the two of them moved instantly.

Nurse Xiao Xu moved skillfully and violently, and in her sight, the balloon that blocked the mouth slowly suffocated at a speed visible to the naked eye.

But Brother Qiu Ming stood in front of the patient's nose with one hand, and pulled the other end of the tube tightly with the other.

The balloon, which was still fluffy, was still diligently blocked on the opposite side of the opening, but as the gas was pumped out, the pressure became smaller and smaller, and the speed of bleeding around it gradually increased.

Maybe the next moment, the balloon will not be able to hold it up, it will be pulled out violently, and then blood will gush out.

Everyone's spirits were tense, and the palms of the hands they were clenching were full of sweat.

Zhang Tianyang squinted, and at a certain moment, he suddenly spoke.

"It's now!"

"Poof!"

As soon as the words fell, the bloody air sacs on the screen swept in front of the camera.

Zhang Tianyang's face was not red and his heart was not beating, his wrist flipped over, and he quickly sent the gastroscope in.

The camera panned and rushed to the booked position.

Then, in the next second, blood flooded the entire field of vision.

There is nothing on the screen but red.

"Sent, sent in?"

The chubby Senior Brother Long opened his mouth, only to find that his mouth was a little dry and his voice was a little hoarse.

He rested his elbows on the shelf next to him, and the trembling camera only improved slightly.

The chubby Senior Brother Long knew that the first case data he collected might be half ruined at the moment.

Because at the most critical moment, he trembled.

But none of that matters.

Importantly, did Zhang Tianyang succeed?

"Delivered to the designated location. ”

The cold Tang Zhizhi's eyes stayed on Zhang Tianyang's wrist for a long time, and the horror in his eyes could hardly be concealed.

The gastroscope tube is black, the length mark on it is white, and the scale that now stays at the patient's mouth is not more than one millimeter, and it is not less than one millimeter, which is the depth that Zhang Tianyang said before, to be sent in.

Say from which direction to enter, from which direction to enter, as deep as you say, as deep as you say.

He really, does what he says!

"Pay attention to the blood flow. ”

Zhang Tianyang squinted, stared at the screen, instantly judged the situation, and then spread his right hand.

Luckily, it happened to be one of the models he modeled with Tang Zhuzhi before.

Nurse Xiao Xu quickly sent the prepared operating handle to Zhang Tianyang.

I haven't forgotten to clench my fist.

"Come on, Dr. Zhang!"

For now, the situation is under control.

Therefore, Zhang Tianyang nodded politely at Nurse Xiao Xu, and then paid attention to Senior Brother Qiu Ming and Principal Tang while installing the handle.

"Do you see what's coming?"

"I ......"

Senior Brother Qiu Ming's eyes widened, and he was still carrying a deflated three-chamber and two-sac tube dripping with blood in his hand, but the front half of his body was almost in front of the screen.

He seemed to see something.

It's as if I didn't see anything.

Senior Brother Qiu Ming tried to struggle, his other hand scratching in front of the screen.

"Yes...... From here, here? and again...... To this point?"

Zhang Tianyang glanced at him and continued to send the handle.

"Guessed wrong. ”

"Hmm......"

Senior Brother Qiu Ming's face showed obvious disappointment, but it quickly changed to "I know".

"Is it E3?"

The cold Tang Zhuzhi suddenly spoke, and his expression was a little unconfident.

But Zhang Tianyang glanced at him unexpectedly.

"That's right, that's the third case we're analyzing at point E. ”

Zhang Tianyang's eyes lit up slightly, Tang Zhizhi can!

This proves that his plan may be feasible!

Senior Brother Qiu Ming, as always, couldn't see the direction of the flow because he didn't have a model in his heart.

It's like facing a fill-in-the-blank question, there may be tens of thousands of alternative answers, and it's too difficult to get it right!

But if you can make accurate modeling before each gastroscopy to determine the most likely blood flow conditions, then.

Then even if the human eye is not strong enough to capture it, you can determine the direction of blood flow through the clues that can be seen!

It's like turning a fill-in-the-blank question into a multiple-choice question, with only three or four options, and the chances of getting the correct answer are greatly improved using various methods.

Even if it's Meng, there will be a quarter of the accuracy rate!

Modeling works!

This idea works!

Countless thoughts flashed in Zhang Tianyang's heart in an instant, and the next moment, they all fell silent.

For no other reason than that the lever is installed.

He pinched the grip of the handle, squinted, adjusted the angle a little, and sent it inside.

"It's really E3!"

A flame suddenly ignited in the cold Tang Rule's eyes, but then his brows furrowed again.

"However, in the case of E3, the band is the most difficult!"

He recalls the modeling that took place before the surgery began.

Of the three blood flow conditions at point E, the third condition represents a tricky location of the bleeding point.

Even under a gastroscopy with a normal field of view, it takes a certain amount of skill to perform the operation in that position.

What's more, what about a gastroscopy without a visual field now?

Tang Zhuzhi looked at the screen worriedly.

The blood red on it was frighteningly rich, and the handle was sticking out, leaving only a small section next to the camera.

A little farther away, it was tightly obscured by the heavy color of blood.

You can't see the operator at all!

Is it really okay to do blind exercises like this?

"Teacher Zhang. ”

The cold Tang Zhizhi considered this opening, "This way you can't see the operation end." ”

"Aang. ”

Zhang Tianyang responded.

"Do we want to send it inside? Stick it to the stomach wall and then operate it? ”

Tang felt as if he had never said so many words at once.

But he was in a hurry.

"Aang. ”

Zhang Tianyang continued to answer, and his subordinates did not stop.

"But if we send it forward, we don't have a model, maybe we will lose the positioning of point E by then. ”

Tang ruled subconsciously began to sway from side to side in a very small range.

"But if we don't move...... Mr. Zhang, are you listening?"

"Click!"

There was a soft thud.

The expression on Zhang Tianyang's face suddenly relaxed.

Then quickly pull the lever back with your right hand.

"Ah, Senior Brother Tang. ”

Zhang Tianyang blinked and tilted his head.

"What did you just say? I didn't pay much attention. ”

Stealing incense
