In order for this kind of hard pole item to go on the correct path, the angle of entry must be accurate at the beginning.
This is the reason why several teachers nodded sharply before. On the other hand, they all know that don’t listen to Xie’s words of taking it easy. This is only the first step.
Whether or not the correct angle can be controlled depends on the operator's hands, not just calculation.
How can a first-time operator be confident that he can perform operations he has never done before?
It doesn’t matter if you don’t have any experience with the feel. You can still rely on numbers to calculate the experience with the feel.
The sheath can be compared with the value of the weight and length of the puncture needle that was just taken, and then the new hand feel value is calculated in the brain. With this calculated relative value of the feel, the brain tells the hand how many times or minutes it is based on the puncture needle that was just taken.
After putting down half of the strength, it should be almost done.
She is not afraid of minute adjustments. No matter what she has in hand, she has collected the resistance value of the patient's brain tissue when the puncture needle is inserted. She is confident that she will not damage the brain tissue and knows where the upper limit of strength is and where the lower limit is.
.
It’s your first time to hold this thing for puncture, so don’t worry about the awkward movements if you’re not used to it. Don’t be afraid. These medical devices are invented to be convenient for doctors to operate, and basically do not violate the natural movement mechanism of the human hand.
The scope sheath needs to be held by the doctor with both hands, but its handle and the sheath body are at a certain angle, close to 90 degrees, which is convenient for the doctor to hold and insert.
The thoughts in my mind are clear and my mentality is stable. I know how much strength and angle I need to use to hold this thing.
After aiming, adjust the angle in place, put the head of the sheath body into the incision, and enter at a slow pace to avoid damaging the brain tissue as much as possible like a puncture needle.
She did it very smoothly and completed the first stage goal without any obstacles.
Huang Zhilei, who was standing next to her, was dumbfounded.
It cannot be said that he has never seen anyone perform surgery before. When Xie Wanying participated in the orthopedic surgery, he went to watch it. But the shock of witnessing the whole process at close range was completely different from the feeling of watching for a moment.
People say that the junior sister is amazing. As a senior brother, he feels proud and thinks that the junior sister is great. The junior sister has shown her medical theoretical prowess in front of him. But in the end, he has not yet experienced personally how powerful the junior sister is in performing surgeries.
Today's surgery scene and this moment brought him the first wave of visual impact, allowing him to understand what the power of the little junior sister is: the power of the little junior sister is indescribable and makes people unable to figure out why.
Awesome, awesome.
This made him, a neurosurgeon, almost stunned.
What surprised him the most was that the people around him were as shocked as he, the little fool.
Several pairs of eyes stared at Xie Wanying's hands.
"When she was in the second year of General Foreign Language School." Sun Yubo recalled how classmate Xie looked like a baby on the first day she entered the clinic last year. The more she thought about it, the more confused she became. "She was beaten on the back of her hand several times by Teacher Tan."
Student Xie has a good brain, has a solid knowledge of textbooks, and is good at collecting medical information. The only difference is that he lacks experience and accumulation in hands. He, Sun Yubo, is a teacher for Classmate Xie, and there are few places where he can comfort himself. Fortunately, this is
Classmate Xie who clicked on him will be slapped on the back of his hand by Teacher Tan, just like him.
What operations require a high level of touch from the doctor? The more high-end the tools, the higher the need for a doctor's touch. This is the effect that Teacher Tan demonstrated to Xie during his graduation exam.
