However, Professor Deng just glanced into the field of surgery, and his expression was immediately taken aback.

Immediately afterwards, he said to Wei Hong, "Wei Hong, help me test the stability of these tendons."

While speaking, he pointed to Wei Hong the several tendons that had been sewn together.

Wei Hong did as he did, and also tested the functions of finger extension and flexion.

Then Professor Deng took off his eyes, rubbed his glasses, and watched Wei Hong's actions again.

Then he looked at Wei Hong with complicated eyes, pointed to the broken tendons and asked, "What are you doing?"

The tone of voice lost its previous kindness, and the emotion was empty.

In the operating room, needles could be heard in an instant, only the wind from the central air conditioner on the top of the operating room, and the slight sound that could reach the ears, and the intermittent beeping sound from the anesthesia equipment, which was quite aggressive.

Chapter 154 Inviolable!

Deng Liangen is not tall, half a head shorter than his second student Wei Hong, with a slightly fat body. If you walk outside, you will definitely not associate Deng Liangen with the word "professor".

Moreover, Deng Liangen was always amiable and amiable on weekdays, only rarely would he look serious, like now.

He is not tall, but the coercion he exudes naturally shows that he does not lack the posture of a professor, but he has restrained himself all the time.

Deng Liangen glanced at Wei Hong, and there was not much anger in his eyes, but a bit of resentment.

Wei Hong is not the first student of Deng Liangen. Deng Liangen’s first student failed to get a doctoral student after he graduated from graduate school, and he was only a small attending doctor back then, so he returned to the prefecture-level city hospital in his hometown. , and now he is also the director of the ward.

But fortunately, Wei Hong, the second student, was quite competitive. He stayed in the hospital after finishing his doctorate. Now he has obtained the teaching title of associate professor, and he can be regarded as Deng Lianggen's favorite student.Moreover, he is extremely reliable in his daily work. Today, the Second Affiliated Hospital of Shonan University has only two outpatient clinics in the Department of Hand Surgery.

One is Professor Deng Lianggen, and the other is Associate Professor Wei Hong.

Deng Liangen is satisfied with Wei Hong, but today's matter?

Feeling the coercion from Deng Liangen, beside Wei Hong, his students, a professional graduate student and a professional Ph.D. of Deng Liangen took a half step back in an instant.

Before, Wei Hong's own student, Duan Yi, who took the initiative to help Wei Hong with the scissors, took two steps back tremblingly.

They are naturally aware of the seriousness of the matter.But none of them were qualified to have a direct dialogue with Deng Liangen, let alone face to face.

Wei Hong's eyelids twitched violently. Under the cover of the mask, he kept licking his lips with his tongue. This was his subconscious habit when he was nervous.

However, he still braced himself, moved his cheekbones, and took the initiative to pull Deng Lianggen's other hand: "Professor Deng, this is the surface view of the patient's suture. I thought it was also a tendon revision suture."

Wei Hong did not sell his students. Duan Yi is just a student. Although he has obtained a certificate, he can take responsibility, but this is not the tradition of the school.

Deng Liangen has never done anything to sell students.

In fact, replantation of amputated limbs, due to suture problems after surgery, re-revision, the number of occurrences in the Second Affiliated Hospital of Shonan University is not very small.

It can be said that Wei Hong's current strength is still very authoritative in the field of hand surgery in Hunan Province.

As far as he is concerned, at present in Hunan Province, as far as the operations performed by five people are concerned, he will not go back to the furnace to rebuild them.

Three of them dare not, and the other two will save face——

The three who dare not—

One is my master Deng Lianggen, one is Professor Chen from the First Affiliated Hospital, and the other is Professor Zeng from the Provincial People's Hospital.

Professor Zeng from the Provincial People's Hospital and Professor Chen from the Affiliated Hospital of Shonan University are from the same school and are their predecessors.

When my teacher Deng Lianggen was studying, orthopedics was not so detailed.

The hand surgery of Attachment [-] is slightly weaker than that of Attachment [-], which is due to its poor background. Although Deng Lianggen has fought hard all his life and caught up, there is still a small gap.

The two people who gave face, one is Wei Hong's own senior brother, he dare not and will not take the knife rashly.

The other person is his Laozi Yue, who is the director of a prefecture-level city and is now also engaged in hand surgery.

Except for these five people, Wei Hong felt that no matter what the other people's operations were, he could recreate them himself.

Deng Liangen took a deep breath, and then asked again: "You said on the phone earlier that this operation was performed by Director Cai Dongfan from the Eighth Hospital, right?"

Deng Liangen was looking for a way out for Wei Hong.

Wei Hong immediately nodded continuously, his voice became bitter: "Yes, Eighth Hospital—"

The voice was quite tangled: "Master, who is Director Cai Dongfan?"

Wei Hong was already a little worried about these three words. During the meeting before, he never heard that the Eighth Hospital had a great person. The director of the orthopedics department of the Eighth Hospital, whether it was Zeng Yi who was wandering on the edge of hand surgery, Or the old director Wang Yongjin.

Zeng Yi knew them all.

It should be said that knowing Zeng Yi is all because of Wang Yongjin.

Wang Yongjin graduated from the School of Medicine of Shonan University. He is a senior fellow with the director of the orthopedics department of the Second Affiliated Hospital of Shonan University and the affiliated hospital. Wang Yongjin is still a senior fellow.

Even if the two directors saw Wang Yongjin, they would call out Old Brother Wang quite politely.

But this Cai Dongfan, Wei Hong really had never heard of his name.

But Deng Liangen knew, so he looked at Deng Liangen, hoping to be popularized by Deng Liangen.

In order to cover the baldness on his forehead, Deng Liangen's hair was deliberately left in a section. It was slightly deformed under the pressure of the blue sterile surgical cap before.However, now Deng Liangen took the initiative to rub his hair again.

Said: "Cai Dongfan and I have only met a few times and drank wine."

"The character is not bad, he must drink alcohol, but the amount of alcohol is not good, and the wine quality is so-so, easy to drink too much, and make a fool of himself after drinking too much. But he is straightforward, as for his profession?"

"I can't figure it out either."

"I thought something happened to him after he cut off his finger and replanted it, and then he needed follow-up treatment. I thought I would help out if I could. Then let's take a look."

After finishing speaking, Deng Liangen looked at the field of vision in the surgical field again, and frowned lightly: "Just let it go, I'll come to the stage to take a closer look."

I didn't understand it either, but it didn't hinder him. Deng Liangen felt that he had to come on stage to wipe Wei Hong's ass in person.

In fact, generally speaking, few people take over the operations performed by other hospitals.

But when Tan Yuanwu came, someone said hello, and it was not easy to shirk.

The second is that Cai Dongfan is also an acquaintance. With such a relationship, it doesn't matter to clean up the mess.

However, now it seems that the mess was not caused by Cai Dongfan, but by Wei Hong who messed up other people's mess.

Wei Hong nodded quickly, and immediately moved away from the chief surgeon position. The others quickly moved their positions, but Duan Yi, who knew that he was an accomplice, quickly slipped to the position of the Nth assistant, lowered his head, and did not dare to talk to himself. Teacher Wei Hong looked at each other.

Today's pit is likely to be a bit big.

Deng Liangen quickly washed his hands, dressed and went on stage.

After arriving at the chief surgeon's position, he was not in a hurry to repair the two tendons that had been dismantled, but looked back and forth, left and right, and looked at the sutures of the remaining tendons.

Frowning tightly, he asked Wei Hong, "Is the extensor tendon and flexor superficial tendon sutured like this before?"

Wei Hong nodded and said, "Yes, Master!"

You're so good!

It seems that he is no longer an associate professor who can stand alone, but has become a student with Deng Lianggen.

Then he explained: "Master, look at this tendon suture method, which is obviously a modified Kessler tendon suture method. But?"

Among the tendon suture methods, the simple and commonly used suture methods in clinical practice are the Kessler suture method and the modified Kessler tendon suture method.

The Kessler suture secures the tendon at both ends with two needles.

在离断端8～10mm处用3－0不可吸收聚酯材质多股编织缝线(双针线)首先横穿肌腱的一端，在肌腱出针处2～3mm将双直针稍斜穿入肌腱，与肌腱平行后由肌腱断端穿出。

Its advantage is that the operation is easier and the damage is less!

And it has less effect on the blood supply in the tendon.It is beneficial to the early functional exercise of the limbs and reduces postoperative tendon rupture and adhesion.

Can be used for the repair of various tendons.

However, the simple Kessler suture is easy to tear, but the tensile strength can be improved after continuous peripheral suture around the anastomosis of the broken end.

The modified Kessler tendon suture method improved it.

After performing the core suture of the tendon, use No. 5-0 or No. 6-0 single thread for continuous peripheral suture around the anastomosis of the broken end to make the broken end of the tendon repair smooth and smooth.

But the modified Kessler tendon suture that Wei Hong saw today did not include the step of anastomosis around the broken end. Instead, he used multiple strands of Kessler modified tendon suture to suture around the core.

Then Wei Hong said: "Master, Tan Yuanwu, this patient is also a practitioner of orthopedics, so he is quite clear about the medical process. He said that Cai Dongfan also used sodium hyaluronate during the operation."

"At present, although some research groups in the world have explained that after suturing the tendon, applying a small amount of sodium hyaluronate can improve the lubrication of the tendon, but there are also articles showing that the curative effect of sodium hyaluronate is not exact."

"I thought Director Cai was a literature contestant..."

Wei Hong's voice became smaller and smaller, he thought it was him, and Wei Hong's reasoning made sense.

Deng Liangen heard the words, sighed, and said: "Currently there are more than ten methods of tendon suturing. The public says the public is reasonable, and the mother-in-law says the woman is reasonable. There are many methods, which means that each method cannot be perfect."

"At first glance, this suture method looks similar to the modified Kessler suture method, but upon closer inspection, it seems that the essence of it has not been obtained. But according to its suture effect, the tension resistance and the tension of the tendon itself are sufficient."

"And the thread knots are also well stored. When you take out the sutures, you will cause a certain degree of damage to the tendon. I guess there should be something strange about this suture method."

This is also what Deng Liangen couldn't understand.

Deng Liangen himself had never seen this kind of suture, so naturally he didn't know whether it was good or not.

In the final analysis, the name Cai Dongfan is still not strong enough to hold back.

Otherwise, where would there be such a thing as Wei Hong?

Deng Liangen felt that if he was exposed to such sutures for the first time, he would dismantle one or two sutures to see how they are stitched.

But definitely less than Wei Hong.

"However, according to our investigation, it's better not to move any further. Let's sew up the two tendons that were just removed."

"Has the patient's distal blood supply been checked? Is the blood vessel open?" Deng Liangen asked.

For the replantation of amputated fingers, the most important and basic thing is whether the blood supply can be recirculated, and if the blood supply is blocked, everything else is just bells and whistles.

"Blood transport is connected." Wei Hong said hastily.Then, the proper interdigital artery was quickly exposed.

"Master, look, the suture of this blood vessel is also just right. There is no bleeding from such a small-diameter blood vessel. It is really strange." Wei Hong was very puzzled, thinking that he had seen a ghost today.

If Wei Hong didn't feel that he had seen a ghost, then it was called seeing a ghost.

In the simulated copy, Zhou Cheng had sutured blood vessels and tendons for a total of two lifetimes, and only sutured blood vessels and tendons.

Nature is unusual.

Zhou Cheng never thought that other people would understand it, and they must understand it.

It's just that he never thought that Tan Yuanwu would be transferred to another hospital...

"It's a good thing that no blood oozes out." Deng Liangen pondered for a while, and then began to take off his gloves again.

Said: "I'll go and call Director Cai Dongfan to see if he's willing to come over again to finish it off. I just watched their nerve and blood vessel suturing. I think we should not rashly add drama."

Wei Hong was a little stunned: "Master, it's a little uncomfortable to call at this time, isn't it?"

Wei Hong's original intention was to feel a little ashamed. Professor Deng is a professor at the Second Affiliated Hospital of Shonan University, but he called a doctor from the Eighth Hospital to finish the work. It's not a good face.

But Wei Hong didn't say it clearly, he just said that the time was not suitable.

Deng Liangen said: "It's not suitable, it's better than being a comparison place for yourself."

"At that time, the index finger is moving well, but the middle finger has trouble here, then it is not suitable. In the future, when encountering patients with replanted severed fingers, it is better not to rashly perform revision sutures."

Deng Liangen didn't understand it too well, so he didn't dare to rashly become the control group or experimental group for his own comparison.

Wei Hong didn't say much, he just felt guilty.

Now Deng Lianggen's bowing his head was all caused by his own carelessness. How could he feel that Cai Dongfan didn't know these three characters, so he felt that he could boldly renovate?

Deng Liangen quickly found Cai Dongfan's phone number from the address book.

Having had a drink before, it seems that Cai Dongfan took the initiative to pass his call, and then called back.They are all people in the industry, and they are also the director of a hospital. There is no way to help, so Deng Liangen also took the initiative to save it.

The call was connected quickly, but after Deng Liangen explained his meaning.

While driving, Cai Dongfan, who was quite agitated, said very calmly: "Professor Deng, you are laughing at me. The trouble I caused myself, I didn't expect to cause trouble to you, Professor Deng, so you have to worry too much. "

"I just stepped down here, and I haven't eaten yet, so I'm on my way to dinner now."

"Professor Deng, please rest assured that the operation we performed was able to be corrected by you. It is our luck. If there is something wrong in the operation, I hope that Professor Deng can give you some pointers after the correction. , that is the infinite benefit.”

Cai Dongfan thickened his skin, and his mouth was sweet as hell.

Hearing this, Deng Liangen frowned slightly, and said, "Has Director Cai not eaten yet? That's my rashness, but after eating, Director Cai, can you come over and study together? "

Deng Liangen knew what Cai Dongfan meant, and he also heard what Wei Hong said.
