The operating theater gradually returned to silence.
Ling Ran's heart was burning with passion. He calmly hooked the blood vessels and pulled and sutured them one by one. He imagined the appearance of the vascular network in his mind and constructed it with his hands.
He felt like he was building a city by himself.
Modern medicine did not conduct much research on what exactly the vascular network around the Achilles tendon looked like and whether there was a fixed rule. Unlike what many people imagined, modern medicine seemed to have thoroughly researched the human body. In the field of clinical medicine, most of the information surgeons obtained was chaotic.
For example, did the posterior tibial artery radiate three or four perforating arteries? The dissection showed that some people had three, and some had four. Why? Was there a pattern? Not very clear. Where were the positions? Was there a pattern? Not very clear. Did it have other functions? What was the relationship between it and the other human tissues in the feet and legs? Not very clear.
If Academician Zhu Tongyi's plan succeeded and was published in a research paper, it would explain the vascular network around the Achilles tendon in a clinical way and explain the importance of the vascular network.
If it failed, there was no need to say anything else.
Ji Tianlu, who participated in the design of the plan, felt excited. He provided Ling Ran with the blood vessels and watched him connect the broken blood vessels step by step. He could not help but smile.
The plan required a certain level of vascular network to be maintained, and at the same time, they hoped to shorten the surgery time. This required the chief surgeon to be fast and accurate.
Before this, Ji Tianlu specially looked around. The surgeons who could meet their requirements were almost all famous. This was not strange. The chief surgeon they wanted was fast, ruthless, and accurate. They did not want the chief surgeons who were like monkeys in local hospitals, but at least the top level in top hospitals.
In this era, young doctors started to climb the skill tree in their twenties. They only dared to say that they were outstanding when they were around forty years old. They had a skill and could be chief surgeons for a series of more important surgeries.
And among these doctors who were around forty years old, they were considered fast, ruthless, and accurate, so they were always famous.
It was the same in foreign hospitals, and they were even better than in China. Their hospital ecosystem was completely market-oriented. No one would force a doctor to learn basic skills or improve their skills. Those who could make a name for themselves in this area either went home from nightclubs at two in the morning to practice on their own, or were extremely talented geniuses.
Ji Tianlu took the opportunity of the international conference to meet genius-level surgeons in internationally renowned hospitals. However, when faced with these successful surgeons, Academician Zhu Tongyi's plan was not attractive at all.
International surgeons, especially those who specialized in sports medicine, performed surgeries all over the world all year round. They did not have any psychological barriers when it came to China. However, their schedules were so full, and they earned so much, so they were not interested in participating in guided surgeries.
Not even with money.
In fact, even if Liu Weichen was given money to arrange his schedule normally, he might not even be able to schedule his surgery until a few weeks later. His high expectations were something that even high-ranking surgeons could not agree with.
This was just like when Wang Haiyang went to Yiyuan County Hospital for freelance surgery. The first thing he asked was the other party's opinion. If the patient had a request that was out of the norm, such as wanting the finger to regain its function after the finger replantation, then Wang Haiyang would definitely turn around and leave without saying anything.
There was no need to talk about the limits of modern medicine. Surgeons only needed to pay attention to whether they could meet the patients' needs. What was the point of forcefully performing the surgery if he could not achieve it?
Ji Tianlu was originally prepared to persuade Academician Zhu Tongyi to change his plan.
They did indeed come up with Plan B and C, but the value of Plan A was still the greatest.
Ji Tianlu stared at Ling Ran's movements and suddenly felt a little envious. Although medical research was the most important part of medical development, in real life, regardless of whether it was medical research or clinical medicine, in the end, the people who performed the surgery had to be the ones who performed the surgery.
A skillful surgeon was much happier than a simple medical researcher.
"If we connect this part, we can complete the surgery with just one vascular channel." Ling Ran's voice interrupted Ji Tianlu's reverie.
"Is it done?" Ji Tianlu was a little surprised.
"The first of the two vascular channels, we need to suture another section …" Ling Ran was still sticking close to the microscope. He looked at it while he operated. At the same time, he asked for a pair of forceps in a calm voice and firmly clamped the sutured blood vessel gently.
Human blood vessels were very fragile. The blood vessels that could be played around with were basically only a few aorta in the heart, which was the part of a cow's body that was used to make yellow throats.
In hand and foot surgery, practicing to clamp blood vessels had always been a topic.
Clamping the blood vessel firmly was the most important thing, and it was also necessary not to hurt the blood vessel. When faced with blood vessels of different thicknesses and different people, the strength to use to clamp the blood vessel was still based on Ling Ran's intuition, just like what he did before.
Part of the "intuition" came from experience, and the other part came from theory. For example, if there was a person with arteriosclerosis, it was obvious that he could use more strength to clamp the blood vessel, and he must use more strength, or else there would be a situation where the needle would not be able to pierce through the blood vessel.
In general, normal doctors would be very careful when performing surgery. They would try again and again. Only doctors who had reached a certain level would dare to do it right away.
The accumulation behind it was very likely that hundreds or even thousands of surgeries could only be obtained.
Ling Ran repeated the previous operation and carefully sutured the two small blood vessels together.
Once he completed this step, Ling Ran put down the instrument and stood up directly.
"Huh?" Ji Tianlu was stunned for a moment.
"Take a break. Check the vascular channel first," Ling Ran said casually.
Ji Tianlu had not been a first assistant for some time, and he was confused when Ling Ran used him as a first assistant. When he lowered his head to check the blood vessel, he suddenly thought, 'Don't I need to rest?'
Ling Ran took off his surgical gown and gloves. He massaged his neck while he turned around and went out to wash his hands again.
Surgical gloves were not durable items. Usually, after more than three hours of surgery, the physical properties of the gloves would change. In layman's terms, the gloves would no longer fit the hands, and there was a risk of them being damaged. Research stated that when a heart surgery was carried out for three hours, the perforation rate of gloves was 30%, and when the surgery was carried out for five hours, the perforation rate was as high as 65%.
Other than that, the bacteria on the hands of doctors would also accumulate, and the number would increase as time went by.
Therefore, some hospitals suggested that doctors and assistants change gloves when the surgery was more than four hours long, but in the academic field, some people called for changing gloves after one and a half hours.
Ling Ran did not pay attention to this information before. In short, he did not know. It was only because he had been relatively free recently and read more research papers that he noticed this.
Considering the total length of the surgery today, Ling Ran decided to change gloves now and take a good rest.
Suturing blood vessels was great, but it also used up a lot of stamina and concentration.
Ji Tianlu carefully checked each blood vessel.
The first assistant's job was to check and make up for the chief surgeon's mistakes. In other words, a first assistant who was qualified to check and make up for the chief surgeon's mistakes was already a first assistant who was valued, and he should be happy.
Ji Tianlu did not feel happy, but he admired Ling Ran a little.
It was already so tiring to check the blood vessels, so how tiring would it be to suture them?
He used to work on orthopedic surgeries, and he did not have much experience in suturing blood vessels. During the process of checking, he gradually realized how complicated it was.
The vascular pathway Ling Ran built was not a simple loop. He had taken into account the situation where there were blood vessels that were not sutured perfectly. Even if the probability of that happening was very low, there were many broken points to be sutured. If there was only one loop, then as long as there was a problem with one broken point, the entire vascular pathway would be meaningless. It was the same as raising the difficulty to the level of finger replantation.
Ling Ran, who had performed many finger replantation surgeries, knew very well the limitations of such a vascular pathway. Therefore, the vascular pathway he made was more like an interchange system. It was useless to simply build a backup blood vessel, because sometimes there might be systemic damage, such as a fall, bump, or sprain during the recovery period. All of these might cause the backup system to be damaged at the same time.
Therefore, the intersecting and interchangeable blood vessel pathway was the focus of Ling Ran's design.
This made the suturing more difficult, but it also showed the safety that the plan did not have.
When Ling Ran came back, Ji Tianlu, who had already checked until his neck hurt, quickly said, "There's no problem with the blood vessel suture. I think the safety of this vascular pathway is enough."
In other words, there was no need to make a backup vascular pathway anymore.
Ling Ran did not express his opinion. He put on a new pair of gloves and said, "Let go and let me take a look."
Both of them sat under the microscope again, and Ling Ran gently loosened the clamp on the posterior tibial artery.
The blood flowed smoothly, and there was no bleeding.
"There's no problem?" Lu Wenbin was also quite nervous.
However, a mission notification appeared in front of Ling Ran.
[Mission: Stand Out]: Completion rate: 75%.
A completion rate of 75% meant that the function of Liu Weichen's Achilles tendon could be restored by about 75%. For an invasive surgery, this recovery rate was very good. Moreover, if the rehabilitation and exercise were done well in the later stages, there would be a certain degree of improvement.
However, it was definitely not enough to participate in a world-class competition with a 75% Achilles tendon.
It could only be said that the current surgery was done well, but there was no miracle.
