Focusing 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 an important point.
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 is not going to use the 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.
I used to think that sewing tofu on the outside of the liver and gallbladder was a neurosurgery job, but I saw with my own eyes that the shape of the brain tissue really looked like a block of tofu.
Tofu is characterized by being soft and easily broken into pieces. The surface forms self-tension like a film to maintain its shape. Brain tissue is somewhat similar to this. If we really dig into the details, the walking arteries and veins in the human brain, as well as special structures such as the ventricles, cannot be summarized as tofu. The brain puncture needle is mounted. This time the doctor needs to calm down. After all, it is a critical step. Then he can visually inspect or 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. Be very careful with the depth of penetration so as not to penetrate the arachnoid membrane. According to the previous surgeon's own estimation, the length of the cerebral catheter of the shunt is almost the same as seven.
Since the tissue is similar to a piece of tofu, insert it slowly and steadily when puncturing to avoid excessive damage. During this period, Xie Wanying was seizing the opportunity to accumulate skills. She actually did it once before, that time for Teacher Xin.
After puncture, it is the turn of upper ventriculoscopy.
Huang Zhilei hurriedly looked at the Song cat again.
Song Xuelin wanted to roll his eyes at the little idiot senior. 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 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 herself. She must 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. This sheath feels different from the puncture needle and is heavier than the puncture needle.
When the puncture needle is inserted, the surgeon can hold it with one finger to prevent the puncture needle from becoming unstable and tilted. This is no longer the case with ventriculoscopy. The doctor holds the handle of the scabbard with both hands, just like holding the end of a sword with both hands and inserting it into it.
Everyone knows that such an operation tests the stability of the doctor's hands.
"Angle is very important." Xie Wanying said.
With her words, the bosses around them nodded.
Song Xuelin handed her the ventriculoscope directly.
Maybe he would have hesitated before, but now he no longer has to. Because Dr. Xie obviously had some training as a major surgery surgeon when he came back this time.
Xie Wanying recalled that the fairy brother was so kind to her that there was no need to say more. How would any other instructor give her such an opportunity to practice?
Cao Zhao: Don’t let the rich water flow to outsiders’ fields.
