"Another type of stapler doesn't require blood vessel flipping?" The apprentices, who are also top students, immediately drew inferences from his example.
You are right, the S stapler does not require blood vessel turning.
"Without turning over the blood vessels, do you put it in and directly staple it?"
There are ready-made things on site that can be seen intuitively, but the structures of these medical devices are not as clear at a glance as wrenches, axes, and knives. There are various mechanisms hidden inside that are not easy to understand.
The little followers didn't dare to touch it, and they had never seen the teacher use it, so they had to ask the senior sisters and brothers: "Is there a nail inside?"
The clamp-type stapler continues the idea of the previous stapler-type stapler and has nails.
Laymen all know that using a stapler to staple will damage paper, so this type of stapler-type stapler will naturally be more damaging to blood vessels.
The improved anastomosis device wants to avoid too much damage to the blood vessels, and it is best not to use nails. At this time, if you want to connect two blood vessels together again, you need to introduce another idea, using a card.
The idea behind this is easy to understand. Just think about how a fish bone can get stuck in the esophagus and be completely unable to move.
...
...
"I understand. Put this petal-shaped stent on the end of the transplanted blood vessel and place it into the target blood vessel to stretch it open, so that the end of the transplanted blood vessel is stuck inside the target blood vessel and cannot move."
An external stent is then added to the anastomosis site for double insurance. After the blood vessels are clamped, they are not allowed to move, and the two blood vessels are pressed tightly together, waiting for the human tissue cells to grow naturally and slowly grow together.
"Everyone says that the S stapler is very good, so why are you afraid that it can't be used in current surgeries?" the apprentices asked again.
Xie Wanying wanted to test her junior sisters and fellow students: "Now that you know the principles of use of these staplers, let me ask you what type of staplers they are."
The classification mentioned above is one way of classification, and what Senior Sister Xie is testing now is another way of classification.
The room suddenly became quiet for one second, two seconds, three seconds...
The other seniors all saw it, and the three disciples were immediately stumped by Teacher Xie’s questions.
Mi Siran, Mi Wenlin and Zhang Shuping were all sweating: They never thought that Teacher Xie would test people, and that he would really test students to death.
A low chuckle was heard over the phone first.
"What are you laughing at?" Huang Zhilei took a picture of Song Mao who was grinning.
If you ask Song Tiancai what he is laughing at, it is definitely not because of these little followers. What these little followers learn has nothing to do with him, Song Tiancai, because Song Tiancai does not like to be a teacher.
In fact, Song Xuelin had seen such a scene in the hepatobiliary surgery department before.
The stubborn Dr. Xie, when he becomes a teacher, will only become an even more stubborn Teacher Xie, and will be strict with you to the end.
Hearing Song Mao's laughter, the group of disciples became even more sweaty.
Is Teacher Xie testing their medical memory?
Obviously not.
Teacher Xie said that the prerequisite for the test question is that you know the principle, which means that this question is a reading comprehension question similar to the college entrance examination.
Do you think Teacher Xie is vicious? It seems that he is as vicious as Boss Zhang.
We won't test you on something as easy as memorizing something. We'll test you on your thinking ability like the high-scoring questions in the college entrance exam. Who asked you to study medicine at a prestigious university? You must be a top student.
"What is it?" Mi Wenlin felt like he was going to get dizzy from thinking about it, and slumped down in the chair in surrender.
Zhang Shuping turned his head back and forth, not knowing where to go to find another library to answer Teacher Xie.
Looking at the two people's reactions, the other seniors did not criticize them, but they had to admit that it was not easy to be Teacher Xie's student. Misran racked his brains and continued to think: "Is it like an engine?"
