It is easy to operate things that don't feel heavy in your hand.
It is no longer difficult to hold things, you need to think about what you are mainly doing with them.
The mirror arm is an important auxiliary force for the main knife.
As for assisting the main surgeon, Mr. Tan said that lighting, she can understand it as a surgical field. As long as it is the surgical field, it can be compared to the retractor in traditional surgery. It exposes the surgical field as much as possible so that the surgeon can see clearly where the knife can be cut.
The difference is that the retractor is to open the area of the visible field of view in the human body, which can be directly expanded. The area exposed by the laparoscope is only a small ellipse, and it is doomed that the assistant needs to fill in the entire surgical field picture for the surgeon.
The draw hook is where the main knife is pulled. If it is a laparoscopy, it should be where the surgeon should be.
After thinking about this, Xie Wanying's thoughts became clearer. With a clear mind, hands are more comfortable, knowing how to move.
The main knife and the first assistant are ready to insert the operating cannula into other openings.
Sun Yubo let go of his hand a little, and found that she had stopped the mirror body firmly in place, and praised: "Not bad, it's strong."
Girls are always easy to lose strength, but in fact, they lack strength so they are not stable enough to hold things. To maintain operation on a level surface, continuous force is required.
"It's almost like a hook." Xie Wanying shared her answer with the teacher.
Sun Yubo blinked, and the clever student seemed to have grasped the point, so he tested her further: "Do you know what to see in the abdominal cavity as a reference?"
When a rookie performs laparoscopy, the first problem he has to face is nothing more than a lack of sense of direction. One must have a reference when looking at anything, otherwise it is like looking at the vast ocean.
"Uterus." Xie Wanying replied immediately.
There is no need to contact medical textbooks. Didn’t the first photo taken by Mr. Tan just go to the uterus
The uterus is such a big organ that it is not used as a reference. The surgeon is either brainless or blind.
Ah? Sun Yubo laughed inwardly: Sister Shuang, you are too good at learning and selling.
Hearing her answer, Tan Kelin glanced at her quietly from the corner of his eyes: Stealing teacher~
"Only the uterus?"
Teacher Xiao Sun has increased the difficulty of the exam.
Xie Wanying recalled Teacher Tan's operation again, and replied: "Whether it is forward, backward, left or right, the horizontal line is required as the target reference. The uterus is too large to meet this condition, and some anatomical planes are needed to guide the operation. Obviously, the two sides The sacroligament is a reference line. The anterior abdominal wall is the reference surface."
There was a strange silence in the operating room. A large number of advanced students standing behind listened to her words, as if they were enlightened. It turned out that they had stood here for a long time and studied for a long time, so it was better for her to sum up a sentence.
"You have secretly learned from Teacher Tan to such an extent—" Sun Yubo said in a low voice when he was surprised by her, because he knew that this could only be a further result of what she learned and sold just now.
Tan Kelin paused his hands, and in his silent eyes, he seemed to be thinking about it: If he was stolen by a student like this, will this student want to steal all his skills next time
Regarding this, Xie Wanying calmly returned a look to the teacher: Didn't she let her learn? Wouldn't what she learned be the honor of the teacher
I don't know how the teacher on the scene is feeling, anyway, Director Yang behind laughed out a duck voice: quack, quack~
Sun Yubo frowned if he had known that a leader would come to inspect it. As soon as the boss entered the door, the trainees made a lot of noise.
