For this kind of hard pole item to make it go on the correct path, the angle of entry at the beginning must be accurate.
This is the reason for the sudden nods of the previous teachers. On the other hand, everyone knows, don't listen to Xie's easy-going words, this is just the first step.
Whether you can control the right angle depends on the hands of the operator, not just talking about it.
How can a first-time operator be sure that he can do what he has never done before
It doesn't matter if you don't have hand feeling experience, hand feel experience can also be calculated by numbers.
The mirror sheath can be compared with the value of the weight and length of the puncture needle just taken, and then the value of the new feel can be calculated in the mind. With the calculated relative value of the hand feeling, the brain tells the hand that it should be almost the same when it is put down according to the strength of the needle that was just punctured.
Don’t be afraid of fine adjustments. No matter what is in your hand, when the puncture needle is punctured, she has collected the resistance value of the patient’s brain tissue. She has a bottom line in her heart, so that the brain tissue will not be damaged and pierced. She knows where the upper limit of strength is and where the lower limit is. .
It's the first time to hold this thing to do a puncture, I'm afraid the movement will be awkward if I'm not used to it. There is nothing to be afraid of. These medical devices were invented to be convenient for doctors to operate, and there is basically no movement mechanism that violates the natural movement of the human hand.
The mirror sheath needs to be held by the doctor with both hands, but its handle and the sheath form a certain angle close to 90 degrees, which is beneficial for the doctor to hold and insert.
The thoughts in the mind are clear, the mentality is stable, and you know how much strength and angle you need 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, avoiding damage to the brain tissue as much as possible like a puncture needle.
She did it smoothly and completed the first stage of the goal without hindrance.
Huang Zhilei, who was standing next to her, was dumbfounded.
It cannot be said that he has never seen others undergo surgery before. He went to watch when Xie Wanying participated in the 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 great, and he feels proud of being a senior brother, and also thinks that the younger sister is amazing, and the younger sister has shown her greatness in medical theory in front of him. But in the end, he has not personally experienced how powerful the little junior sister's surgery is.
Today's surgery scene and this moment brought him the first wave of visual impact, and made him understand what is the power of the little junior sister: the power of the little junior sister is so amazing that people can't figure it out. Great and great.
This is what made him, a neurosurgeon, feel like he was going crazy.
What surprised him the most was that the people around him were as shocked as he, a little idiot.
Several pairs of eyes stared straight at Xie Wanying's hands.
"She used to be in the Second General Secondary School." Sun Yubo recalled the fledgling appearance of classmate Xie who stepped into the clinic on the first day last year. The more she thought about it, the more confused she became. "She was beaten on the back of the hand several times by Teacher Tan."
Xie has a good brain, a solid knowledge of textbooks, and is good at collecting medical information. The only thing is that there is no experience accumulation in the feel. He, Sun Yubo, was a teacher for classmate Xie, so he rarely comforted himself. Fortunately, classmate Xie is no different from him in this regard, he will be beaten on the back by Teacher Tan.
What kind of operation has high requirements on the doctor's hand feeling? Higher-end tools have higher requirements on the doctor's feel. This is the effect demonstrated by Mr. Tan when Xie students took the exam.
