"Another stapler that doesn't need to turn over the blood vessels?" The apprentices who are also top students immediately drew inferences.
You are right, the s stapler does not need to turn over the blood vessels.
"Don't turn over the blood vessels, do you put them in and nail them directly?"
There are ready-made things on the scene that can be seen intuitively, but the structure of these medical instruments is not as clear as a wrench, axe, and knife. It is not easy to understand the various mechanisms implied in it.
The little followers didn't dare to mess with it, and they had never seen the teacher use it before, so they had to ask the seniors and brothers: "Are there any nails in it?"
The clamp-type stapler is a continuation of the idea of the previous stapler-type stapler with nails.
Laymen know that using a stapler will damage paper, and this type of stapler will naturally damage blood vessels.
The improved stapler wants to avoid too much damage to blood vessels, it is best not to use nails. At this time, if you want to connect the two blood vessels together, you need to introduce another way of thinking, using cards.
The idea of the card is easy to understand. Think about how a fishbone can get stuck in the esophagus and cannot move at all.
"Understood. Put this petal-shaped stent on the end of the transplanted blood vessel and put it into the target blood vessel to stretch it out, so that the end of the grafted blood vessel will be stuck in the target blood vessel."
An external bracket is added outside the anastomosis for double insurance. After the blood vessel is blocked, the two blood vessels are tightly attached and only wait for the natural growth of human tissue cells to grow together slowly.
"It is said that the S stapler is very good, why are you afraid that it will not be used in the current surgery?" the apprentices asked again.
Xie Wanying wants to test the junior sisters and juniors: "You know the working principle of these staplers, and ask you which type of staplers they belong to."
The classification mentioned above is a classification method, and now Senior Sister Xie is taking another classification method.
The room was immediately quiet for one second, two seconds, three seconds...
All the other seniors could see it, and the three apprentices were all overwhelmed by Teacher Xie's question.
Mi Siran, Mi Wenlin, and Zhang Shuping were sweating profusely: I never thought that Mr. Xie would test people, and if he really did, the students would die.
There was a low chuckle first on the phone.
"What are you laughing at?" Huang Zhilei took a photo of the snickering Song Mao.
If you ask Song Tiancai what he is laughing at, it must not be laughing at these little followers. It has nothing to do with Song Tiancai how these little followers learn. Song Tiancai doesn't like to be a teacher.
In fact, Song Xuelin had seen such a scene in the Department of Hepatobiliary Surgery.
Dr. Xie, who is obsessive, becomes a teacher who is even more obstinate. He will be strict with you to the end.
Hearing Song Mao's laughter, the disciples in this group became more and more sweaty.
Did Mr. Xie test their medical memory
Obviously not.
Teacher Xie said that the premise of 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 Mr. Xie is poisonous? It seems that he is vicious in a fight with Mr. Zhang.
It’s not something as easy as your endorsement, it’s like a high-score question in the college entrance examination that tests your brain’s thinking ability. Whoever told you to come to a famous school to study medicine, you should be a top student.
"What is it?" Mi Wenlin felt that he was going to faint, and he slumped on the chair and surrendered.
Zhang Shuping turned his head back and forth, not knowing where to go and move to another library to answer Mr. Xie. Looking at the ghostly appearance of these two people, the other seniors did not criticize, but it must be admitted that it is not easy to be Teacher Xie's student. Mi Siran racked his brains and continued to think: "Is it like an engine?"
