Other students and other doctors are all watching from the outside.
Cao Yong waited for the need to go on stage to finish. Seeing that he didn't intend to wash his hands, the second general foreigner showed that he had full confidence in the subordinate gang.
After washing hands, put on surgical gowns.
To be honest, this operation can be done by almost one person, and the assistant may not have to do anything. The real significance of the assistants today is that the chief surgeon is the first person to be the chief surgeon on the neurosurgery operating table, and it is the first time to be exposed to this type of shunt and ventriculoscopy.
Since classmate Xie was a student from their department, the teacher of Puwai No. 2 stood here watching, feeling a little fluctuating in panic.
When the teacher sees the student he likes showing his face in front of other people, he is also afraid that the student will suddenly fall down.
Fortunately, student Xie was very calm and composed as always, as if his nerves were all frozen, and he was not affected by the surrounding atmosphere in the slightest.
She stretched out her right hand, the nurse handed over the scalpel, Xie Wanying took it, and made a small arc-shaped incision on the predetermined position. The advantage of this arc-shaped cut is that it will not be parallel to the shunt tube, which can reduce the chance of frictional damage to the tube. Surgical incisions are always as small as possible for patients, and doctors do their best to make small incisions within their own technical range.
For Mr. Xie, who came to try it on the first day, the first time he went down, he didn't know whether he was overconfident or not afraid of things. That is, if the incision is found to be small, it can be enlarged.
Classmates Wei and Pan, who accompanied Classmate Xie all the way from the Department of Pediatrics, knew that this was not the case. Classmate Xie must have calculated all the limit values early, and there would be no situation where the incision was not large enough. This is what student Xie is best at. Even if the incision is small, he can use the three-dimensional brain to move out of the field of surgery.
As we have said before, the scalp is rich in blood vessels and prone to massive bleeding. In fact, this first scalp operation is a test of the doctor's basic skills.
During this cut, two large pieces of yarn are ready next to the preset cut. The left hand of the chief knife who did not hold the knife pressed a piece by himself. The other piece is pressed by an assistant, and is fully prepared.
After a while, the bystanders found that it was fine and there was not much bleeding. The remaining blood from the severed scalp was sucked clean.
Neurosurgery also has a wide variety of retractors. The scalp retractor on the main knife can be accurately called a craniotomy soft tissue lamina spreader, which is pincer-shaped, and the two pincer heads are claw-like hooks like a comb. Put this thing into the incision, adjust and fix it after supporting the scalp.
Determine the position of the skull under the scalp again, and drill the hole with the electric drill.
This kind of operation has been seen by the teachers, and Teacher Xin can do it at one time. She is not afraid, and she can get started quickly.
While she was drilling, Dr. Song could be seen helping her adjust the ventriculoscope.
Why is this Song cat moving so fast? Huang Zhilei frowned at his junior.
It's the first time for the little junior sister to be the surgeon, so she can't be urged to be a good assistant.
Dr. Xie didn't need him to remind him, he was afraid that if he moved slowly, he wouldn't be able to cooperate. Song Xuelin didn't dare to stop at this point.
People watching around vaguely sensed that the operation was a bit too smooth and abnormal: the main reason is that the chief surgeon seemed to be too experienced, and he didn't look like a novice at all. The problem is that the chief surgeon is obviously a "novice".
Xie is always so calm. Wei Shangquan wanted to touch his beating heart. He didn't have a heart attack, but his blood was boiling with encouragement.
