Her attention was only on her scalpel. Xie Wanying held the scalpel again and made a cross incision on the dura mater exposed after drilling.
After incision, continue to carefully clean up any blood clots. This is very important.
With such a small incision, the diameter of the exposed hole is only about one centimeter, and it is almost impossible to see what is inside. The surgeon will not intend to use instruments to remove the inside himself.
Looking at the place where the incision was made, the doctor's field of vision was filled with something white and soft, which was obviously brain tissue.
In the past, sewing tofu on the outside of the liver and gallbladder was said to be a neurosurgery job, but I saw with my own eyes that the shape of the brain tissue really looked like a block of tofu.
The characteristic of tofu is that it is soft and easy to break into pieces. The surface forms self-tension like a membrane to maintain its shape. The brain tissue is somewhat similar to this. If you really look into the details, the human brain has walking arteries and veins plus special structures such as the ventricles.
We can't generalize that everything is tofu. The brain puncture needle is launched. This time the doctor needs to calm down. After all, it is a critical step. Then he can visually check or if he is not confident, ask the assistant to help estimate whether it enters the brain ventricle at this position.
Holding the puncture needle in hand, the surgeon must accurately determine the direction of the puncture needle, which is towards the midpoint of the line connecting the two external ears. The penetration depth must be very careful, so as not to penetrate the arachnoid membrane. According to the surgeon's own estimation before, it is
The length of the cerebral catheter of the shunt is almost the same as seven.
In view of the tissue that resembles a tofu block, the puncture should be done slowly and steadily to avoid excessive damage. During this period, Xie Wanying was seizing the opportunity to accumulate touch. In fact, she had done it once before, that time for Teacher Xin.
After puncture, it’s the upper ventriculoscope’s turn.
Huang Zhilei hurriedly looked at the Song cat again.
Song Xuelin wanted to roll his eyes at the little idiot senior, but look, he already knew that he was afraid it would be too late.
The intraventricular mirror is like a puncture needle. First put the scope sheath and enter along the original entrance of the puncture needle.
When explaining this to the junior sister who was operating a ventriculoscope for the first time, Huang Zhilei was more nervous than the person involved. It can be said that the emperor is not in a hurry to kill the eunuch. After giving the lecture on the spot, he said: "Do you need me to demonstrate to you first?"
"Is it right to enter the same way?" Xie Wanying asked.
As long as she enters the same way, she doesn't have to worry about it. She will definitely remember the surgical approach she just had.
What Huang Zhilei wanted to express was: "Take off the ventroscope sheath."
This time, Xie Wanying understood what Senior Brother Huang said. The feel of this mirror sheath is different from that of a puncture needle. It is heavier than a puncture needle.
When the puncture needle is used for puncture, the surgeon can hold the holder with one finger to prevent the puncture needle from being unstable and tilted. This is not the case with the operation of the ventriculoscope. The doctor holds the handle of the scope sheath with both hands, just like holding the end of a sword with both hands.
Insert it inside.
We all know that such an operation will test the stability of the doctor's hands.
"Angle is very important." Xie Wanying said.
With her words, the bosses around her nodded.
Song Xuelin handed her the ventriculoscope directly.
Maybe he would have hesitated about this before, but now he no longer has to. Because Dr. Xie had obviously trained as a major surgery surgeon when he came back this time.
Xie Wanying recalled that the fairy brother was so kind to her that it goes without saying. How could other instructors give her such an opportunity to practice.
