The operating room gradually became calm.

Ling Ran's heart was burning, and his face was calm as he hooked the blood vessels, pulling and suturing one by one, imagining the appearance of the blood vessel network in his mind, and constructing it in his hands.

It feels like one person is building a city.

Is there any definite rule about what the vascular network around the Achilles tendon looks like? Modern medicine has not done much research on it. Unlike many people imagine, modern medicine seems to have thoroughly studied the human body. In clinical medicine, surgeons

Most of the information obtained is chaotic.

For example, are the posterior tibial arteries radiating out three or four perforating arteries? Anatomy shows that some people have three and some people have four. Why? What is the rule? It is not very clear. Where are the locations?

Is it regular? Not very clear. Does it have other functions, and what is its relationship with other human tissues in the feet and legs? Not very clear.

If Academician Zhu Tongyi's plan is successful and published, it will be using a clinical medicine approach to explain the vascular network around the Achilles tendon and the importance of the vascular network.

If it fails, then there is no need to say more.

Ji Tianlu, who participated in the design of the plan, was very excited and helped Ling Ran connect the broken pipelines. He watched him connect the broken pipelines step by step, and a smile appeared on his face.

The plan requires maintaining a certain level of vascular network, while also hoping to shorten the operation time, which requires the surgeon to be fast and accurate enough.

Before that, Ji Tianlu made a special inspection. Almost all the surgeons who could meet their requirements were well-known. This is not surprising. The speed, precision and accuracy they required were not the monkey-shaped surgeons who were the king in local hospitals.

, and at least it is the top level of a top hospital.

In today's era, young doctors start to climb the scientific and technological tree in their twenties, and only when they are about 40 years old can they be said to have emerged and become skilled enough to perform a series of more important surgeries.

Among these high-tech doctors who are around 40 years old and in the prime of life, they are fast, ruthless and accurate doctors, and their reputation is always huge.

Foreign hospitals are similar, even better than domestic ones. Their hospital ecosystem is completely market-oriented. No one will force a doctor to learn basic skills or make improvements.

Either you go home from the nightclub and practice on your own, or you become a genius with extraordinary talent.

Ji Tianlu took advantage of the opportunity of international conferences to meet talented surgeons in internationally renowned hospitals. However, in the face of these successful surgeons, Academician Zhu Tongyi's plan was not attractive at all.

International-class surgeons, or sports medicine surgeons, perform surgeries all over the world all year round. They have no psychological barriers to coming to China, but their schedules are so full and they earn so much.

, there is no interest in participating in guiding the surgery.

Not even giving money.

In fact, even if Liu Weichen arranges a normal schedule for money, he will not necessarily schedule it until a few weeks later. His high requirements are even more unacceptable to senior surgeons.

This is like when Wang Haiyang goes to Yiyuan County Hospital to have a flying knife. The first thing he asks is the other party’s wishes. If the patient has an extraordinary request, such as wanting the finger to fully recover its function after the amputated finger is replanted, then Wang Haiyang

He must have turned around and left without saying anything.

There is no need to say what the limits of modern medicine are. Surgeons only need to focus on whether they can meet the needs of patients. If they cannot meet the needs of the patient, what is the point of forcibly performing surgery?

Ji Tianlu was already preparing to persuade Academician Zhu Tongyi to modify the plan.

They did make plans B and C, but the value of plan A is always the greatest.

Ji Tianlu stared at Jianran's actions and suddenly felt a little envious. Although medical research is the most important part of medical development, in real life, whether it is medical research or clinical medicine, it must ultimately be implemented by the implementers.

A highly skilled surgeon is much happier than a simple medical researcher.

"If we connect it here, a passage will be completed." Ling Ran's voice interrupted Ji Tianlu's reverie.

"Is it done?" Ji Tianlu was a little surprised.

"The first of the two passages, suture another section..." Ling Ran was still close to the microscope, watching and operating at the same time. At the same time, he asked for tweezers in a calm voice, and gently clamped the sutured blood vessels steadily.

live.

Human blood vessels are very fragile, and the only blood vessels that can be manipulated are basically a few aortas in the heart, which are the parts of the cow's body used to make yellow throats.

In hand and foot surgery, practicing blood vessel clamping is always a topic.

Stable clamping is the first priority, and it is also necessary not to damage the blood vessels. Faced with blood vessels of different thicknesses and different people, how much force should be used to clamp them, just like Ling Ran did before, can only be determined by feeling.

Part of the "feeling" comes from experience, and part of it comes from theory. For example, if a person has arteriosclerosis, the blood vessels that look the same to the naked eye can obviously be clamped harder, and the clamping must be stronger.

Otherwise, if the needle is poked, it may not be able to break through.

Generally speaking, normal doctors perform surgeries carefully and try again and again. Only doctors who have reached a certain level dare to do it immediately.

The accumulation behind it is likely to require hundreds or even thousands of surgeries to obtain it.

Ling Ran repeated the previous operation and carefully sewed the two small blood vessels together.

After completing this step, Ling Ran dropped the equipment and stood up directly.

"Huh?" Ji Tianlu was stunned for a moment.

"Take a rest and check the passage first." Ling Ran said very casually.

Ji Tianlu hadn't been a first aid for some days, and everyone who was used by Ling Ran as a matter of course was confused. When he lowered his head to check the blood vessels, he suddenly thought: Don't I need to rest?

Ling Ran took off his surgical clothes and gloves, and while massaging his neck, he turned around and went out to wash his hands again.

Surgical gloves are not durable goods. Generally speaking, after more than 3 hours of surgery, the physical properties of the gloves will change. In layman's terms, they no longer fit the hand so well, and there is a risk of breakage. There are studies

It is said that when the heart surgery lasts for 3 hours, the perforation rate of the gloves is 30%, and when the heart surgery lasts for 5 hours, the perforation rate is as high as 65%.

In addition, bacteria on doctors' hands are also constantly accumulating and increasing over time.

Therefore, some hospitals recommend that doctors and assistants change gloves when the operation lasts for more than 4 hours, while in the academic community, some people call for changing gloves after 1.5 hours.

Ling Ran didn't pay attention to this information before. In short, he just didn't know. It was only recently that he had been free and read more papers that he noticed this aspect.

Considering the total length of today's surgery, Ling Ran decided to change gloves now and take a good rest.

Suturing blood vessels is certainly enjoyable, but it also consumes a lot of energy and attention.

Ji Tianlu carefully examined each blood vessel.

The first assistant is to check and fill in the gaps for the chief surgeon, or in other words, the first assistant who is qualified to check and fill the gaps for the chief surgeon is already a valued assistant and should be happy.

Ji Tianlu had no happy thoughts, but he was somewhat impressed.

How tiring is it to sew up a blood vessel that is so tiring to examine?

He used to do bone and joint surgery, but he didn't actually have a lot of experience in suturing blood vessels. Only during the search process here did he gradually realize the complexity.

The path established by Ling Ran was not a simple loop, but took into account the possibility of imperfect blood vessel sutures. Even if the chance is very low, considering that there are so many suture breakpoints, if there is only one loop,

As long as there is a problem with one breakpoint, the entire set of sutured pathways will be meaningless, which is equivalent to raising the difficulty to the level of replanting a severed finger.

Ling Ran, who has done many replantations of amputated fingers, is well aware of the limitations of such access. Therefore, the access he created is more like an overpass system. It is useless to simply establish backup blood vessels, because sometimes it may be

Systemic injuries, such as a fall or bump or sprain during the recovery period, may cause simultaneous damage to the backup system.

Therefore, the crisscross and interchangeable vascular pathways are the focus of Ling Ran’s design.

This makes the suturing more difficult, but it also demonstrates the safety that the solution does not have.

When Ling Ran came back, Ji Tianlu, who had already noticed a pain in his neck, quickly said: "There is no problem with the blood vessel suturing. I think the safety of this passage is enough."

The implication is that there is no need to create a backup path.

Ling Ran did not comment, he dressed neatly again, put on new gloves, and said: "Let's take a look."

The two sat back under the microscope, and Ling Ran gently loosened the clamp blocking the posterior tibial artery.

The blood flow was smooth and there was no bleeding.

"Is it okay?" Lu Wenbin was also quite nervous.

In front of Ling Ran, a mission prompt was displayed:

Mission "Emerging": 75% completion.

A completion rate of 75% means that Liu Weichen's Achilles tendon function can recover about 75%. For invasive surgery, this recovery rate is very good. Moreover, if the later rehabilitation and exercise are done well,

There will also be some improvement.

However, it is definitely not enough to participate in world-class competitions with 75% Achilles tendon.

All I can say is that the current surgery was done well, but no miracle happened.

"Build a backup path." Ling Ran no longer hesitated at all.
Chapter completed!
