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 was the reason why several teachers nodded fiercely before. On the other hand, everyone knows that don’t listen to classmate Xie who says it’s easy, this is just 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 actually doesn’t matter if you don’t have any experience in touch. You can still rely on numbers to calculate your experience in touch.
You can compare the weight and length of the sheath with the puncture needle you just picked up, and then calculate the new-feeling value in your mind. With this calculated relative value of hand feel, the brain tells the hand to put down the needle with several times or a fraction of the force of the puncture needle, which should be enough.
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 my first time to hold this thing for puncture. I'm afraid the movements will be awkward because I'm not used to it. Nothing to be afraid of. These medical devices were invented to be easy 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, place 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 smoothly and completed the first stage goal without any hindrance.
Huang Zhilei, who was standing next to her, was dumbfounded.
It cannot be said that he has never seen anyone perform surgery before. He went to watch when Xie Wanying participated in orthopedic surgery. It's just that the shock of witnessing the whole process at close range is completely different from the feeling of watching for a while.
People say that the junior sister is very powerful. He feels proud to be his senior brother and also thinks that the junior sister is very powerful. The junior sister has shown her greatness in medical theory in front of him. But after all, he has not yet experienced personally how powerful the little junior sister's surgery is.
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 it makes people unable to figure out why. Awesome, awesome.
This was shocking to him, a neurosurgeon.
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."
Xie has a good brain, has a solid knowledge of textbooks, and is good at collecting medical information. The only difference is that there is no experience accumulated in the feel. He, Sun Yubo, worked as a teacher for classmate Xie, which was a rare place where he could be comforted. Fortunately, in this regard, Classmate Xie is no different from him and will be slapped on the back of the hand by Teacher Tan.
What operations require a high level of touch from the doctor? The higher the end of the tool, the higher the requirements for the doctor’s touch. This is the effect that Teacher Tan demonstrated to classmate Xie during her entrance exam.
