crazy scalpel

Chapter 45 Assignment

Now that he has recognized the benefits that can be brought by running this experiment, Wang Shicheng is not a person who is indecisive.

Just do what you say, without dragging your feet.

When assigning tasks, Xie Ke told him that he hoped to involve all colleagues, not just a few core members of the original research team—that is, people from Wang Shicheng.

Wang Shicheng was a little surprised, looked at Xie Ke with a complicated expression for a while, and finally agreed.

When the doctors of the Department of Orthopedics were called to hold a mobilization meeting to disclose the experimental project, Xie Ke gave a speech in high spirits.People on the Wang side, such as Sun Liren, have heard Wang Shicheng talk about this for a long time, so they are not very surprised.It turned out that the people on Director Huang's side were really surprised.

Director Huang, Zhao Hua and other attending physicians were also contemplating. Of course they could see what Wang Shicheng could see.

To be honest, when Xie Ke told Zhao Hua and Huang Ningyuan about this matter, although they thought it was a good idea, neither of them thought highly of it. If it was that simple, would others not do it?So they just pushed Xie Ke to Wang Shicheng's side. They thought that if he bumped into a wall, he would give up, so they didn't take it seriously.

But now, like Wang Shicheng, they were shocked by Xie Ke's ability to implement the plan, not just a single idea, from the small details of the experiment to the large commercial operation, which is amazing.

The language Xie Ke spoke on the stage seemed to have a magical power, which fascinated the audience below.Of course, apart from the experiment itself, this obsession is more about the various benefits that follow after the results of the experiment come out.Xie Ke really drew a big picture for them.Director Huang reluctantly admitted that he was also very tempted.

Go ahead to dangers.

Compared with the risks—the most failure is to waste some money to buy experimental skeletons, such as imaging observations, laboratories, etc., and hospitals are all blessed with unique conditions—the rewards are much greater.

Huang Ningyuan raised his eyes and looked at Wang Shicheng.And Wang Shicheng just happened to look over at this time.The eyes of the two met, and they both understood the fiery ambition in the other's heart.

This is an opportunity.It is an opportunity for the Department of Orthopedics of the First Hospital of the city.It is also an opportunity for Huang Ningyuan, Wang Shicheng and others to reach a peak in their lives.It turned out that this peak was hidden in the clouds and mist, and it was difficult to distinguish, but now that the clouds have parted and the fog has dispersed, I realize that it is just a few feet away!

In order to climb this peak, they can go to war, settle their suspicions, and even work together to achieve great things.

Xie Ke finished his speech dryly, and the audience below the stage, led by Director Huang and Deputy Director Wang, burst into endless applause.

Lao Youjun gritted his teeth and clapped his hands.Now, he has to admit that Xie Ke really has the ability.

In neurosurgery, he was favored by Xu Wanjin and wrote articles published internationally.

After coming to the bone, he can still design such an experiment, and he is ahead of others in the application of surgical materials!

It is conceivable that the result of this experiment, if successful, will bring great fame and fortune to Xie Ke.

Lao Youjun became jealous again uncontrollably.

The little devil that had been silent in his heart for a long time came out again.

Since Tong Shouye's death, the Lao family spent so much money in vain, but got no return at all. They have already fallen into the crisis of bankruptcy, and it is a miracle that they can survive until now.What he needs now is money. If there is financial support, there is hope to tide over the difficulties.

Lao Youjun's idea is very straightforward, how to make what Xie Ke should have gotten into his own.And this point actually opened a gap in his blocked thoughts.

During the first phase of the experiment, Xie Ke first contacted the cattle farm and purchased 20 bull calves of cross-bred beef cattle.

This kind of hybrid beef cattle is the introduction of French Charolais cattle, crossed with local cattle, and the offspring bred are good in food quality and large in size.

Xie Ke chose this one after observing several varieties.Because the weight of this kind of newborn calf is basically the same as that of an adult human, it is very suitable for experiments.

I made an agreement with the cattle slaughterhouse that after the slaughter, the calves should be fresh and complete specimens of the thoracolumbar vertebrae. The skins are all sold, and the good parts of the meat are left to be distributed to colleagues in the department to take back to improve food. Everyone is very happy.Even the nurses were assigned, and they all said excitedly that they wanted to help.

After the cows were brought back to the laboratory, they first took pictures to observe the development of the bones. One of them was slightly deformed and could not be used as a specimen.So I paid for another one.

After the 20 specimens were collected, Xie Ke led a group of resident doctors to remove the ribs and some muscle tissue attached to them, leaving the intervertebral ligaments and facet joints intact, then sealed them with double-layer plastic bags, and placed them in a temperature-adjusted -20c inside the fridge.

Xie Ke printed out the progress chart and posted it on the refrigerator when the experiment was needed.The storage period of specimens is 2 weeks to 6 weeks.

Xie Ke divided the 20 specimens into four groups. The first group was infused with the current general material pmma, the second group was infused with cpc, which proved to be not strong enough but degradable, and the third group was Shaker's target material csc was used for infusion molding. As for the fourth group, there was no fracture for comparison.

Xie Ke began to assign tasks to the residents participating in the experiment.

The first is the model preparation group.This group is mainly responsible for making models.In order to maintain a high degree of consistency in the models used for vertebral body shaping in each group, it is best to have the same people make the models, so Shayk specially set up this group.The method of making the model is not difficult, that is, when it needs to be used, take the specimen out of the refrigerator in advance and thaw it at room temperature for 24 hours.Five of them did not move, and the other 5 measured the height of the front edge of the 15th thoracic vertebra with a vernier caliper, which was recorded as the complete height h.

Then, with the 12th thoracic vertebra as the center, the 11th thoracic vertebra above it and the 1st lumbar vertebra below it are all wrapped in epoxy resin, only the middle vertebral body and adjacent intervertebral discs are exposed, keeping The upper and lower bottom surfaces are parallel and the angle formed is less than 1 degree.After doing this, wait for the epoxy to fully harden before experimenting with it.

In order to produce a burst fracture in the specimen, Shayk placed the specimen at the bottom of a graduated container, and then used a metal block weighing one kilogram to make a free fall from a height of 50 centimeters, allowing it to hit the specimen.If the specimen can reach the breakage of a burst fracture—a CT scan is required to confirm—use the formula e=mgh to calculate the energy, otherwise, increase the height of the free fall and continue the experiment.After a burst fracture occurred in the specimen, the post-fracture height h1 of the vertebral body was recorded again.

Then place the vertebral body horizontally, pull both ends to reset the burst part, measure the front edge of the vertebral body again, and record the height h2 after reset.

In this way, the model is prepared.Xie Ke filled in the list of experimental personnel: person in charge, Zhao Hua; implementers: Wei Xingzhong, Lin Weitang; free man: Xie Ke; others: Lao Youjun.

After explaining various matters to Wei Xingzhong, Lao Youjun looked at the "other" and asked, "Then what am I doing?"

Wei Xingzhong said: "You are responsible for measuring and recording data with Lao Lin."

But Xie Ke said no, "Lin Weitang should be responsible for measuring the data alone, because everyone will inevitably have their own fixed habits when using vernier calipers, and it is easy for two people to make mistakes."

Lao Youjun found that Xie Ke was no longer the rookie who could be called out by him at will, and Xie Ke had to arrange what he did!He was very upset in his heart, but he didn't dare to express it on the surface, for fear that Xie Ke would put on small shoes for him, or exclude him from the experimenters.Just kidding, if all the people in the department participated in the experiment, but he was the only one who didn't participate, don't wait for others to tell him, he himself will feel that he can't get along!

But if he was asked to speak soft words, he felt a little speechless, so he froze there in embarrassment.

Xie Ke actually didn't want Lao Youjun to get in touch with the experimental data, even if it was such a non-core content.The reason is simple, he doesn't trust Lao Youjun.

Although he felt that Lao Youjun would not do anything that would harm others or benefit himself, especially if this kind of matter was a major issue for the entire department, he still felt a little uncomfortable.He said to himself, it's not that he is stingy, his brother also said that it is necessary to let go of others.

But it doesn't seem appropriate to exclude him too clearly.Moreover, Cheng Jiang told him about the deal between Lao Youjun and Tong Shouye, but the people in the department were not clear about it.

Xie Ke thought for a while, then said: "You are responsible for guarding the specimen model."

Lao Youjun: "..."

The others didn't think much about it, anyway, the task of the model preparation group was the lightest, so they continued to focus on the arrangement later.

But Lao Youjun thought about it for a long time.Guard the specimen.Keeping specimens?Guard the specimen!

The specimens were not alive and could not move, so they were put in the refrigerator if they were not made into models, and they were used for experiments immediately after being made into models.So how is he going to guard it?The laboratory already had special security guards, and the guards simply said that they didn't need to do anything!

After Lao Youjun figured it out, he was so angry that he trembled slightly.

This is definitely naked, naked, naked, exclusion!But why no one speaks for him? !

Seeing that everyone is excitedly discussing the content of the following experiments, who will do the first group of plastic surgery, who will do the second group of plastic surgery, and the most critical third group!Sure enough, Xie Ke arranged for him!No one objected, and everyone seemed to take it for granted.

At this time, Xie Ke continued to write something on the list of experimental personnel, and then suddenly raised his head and said, "Oh, this fourth group, let's leave it to Lao Youjun."

"Hahahaha!" Everyone laughed, "Those who can do more work, I'll leave it to him."

The fourth group, isn't it just a control specimen that doesn't need to be made into a fracture model?What are you going to do with him?guard?Should he stay in the laboratory to guard a pile of bones? !

Lao Youjun felt that his face was hot, but his heart was cold.
