The focus was only on his own scalpel. Xie Wanying held the scalpel again and cut the dura mater exposed after drilling the hole.

After incision, continue to carefully clean up various blood clots. This is very important.

With such a small incision, the exposed hole is only about one centimeter in diameter, and it is almost impossible to see what is inside. The surgeon will not plan to use the utensils to open the inside by himself.

When you look at the incision, you can take up the doctor's vision, which is white and soft, obviously brain tissue.

I used to sew tofu outside the liver and gallbladder, saying that this was a neurosurgery job. I saw with my own eyes that the appearance of this brain tissue was really like a tofu block.

Tofu is characterized by softness and easy to fragment, and the surface forms self-tension like a layer of membrane to maintain its own shape. The brain tissue is really similar. If you really look at the details, the walking veins in the human brain, plus special structures such as the ventricles, cannot be generalized. When the brain puncture needle is launched, the doctor needs to calm down this time. After all, it is a critical step. If you are not very confident, then ask your assistant to help you estimate whether this position enters the ventricle.

Holding a puncture needle in your hand, the main surgery should be accurately determined. The direction of the puncture needle is toward the midpoint of the line connecting the two external ears. Be careful when the puncture depth is so as not to puncture the arachnoid. According to the previous estimate of the main surgery, it is almost the same as the length of the brain catheter at the shunt tube, which is seven.

Given the tissue similar to tofu chunks, it slowly and steadily penetrates during the puncture to avoid excessive damage. During this period, Xie Wanying seized the opportunity to accumulate the feel. In fact, she did it once before, the one she did it for Teacher Xin.

After the puncture, it is the turn of superior ventricular scopy.

Huang Zhilei hurriedly looked at the Song cat again.

Song Xuelin wanted to roll his eyes at the idiot senior. Look, he had long known that he was afraid that it would be too late.

The ventricle mirror is like a puncture needle, first place the mirror sheath and enter along the original path of the puncture needle.

When expressing this to the junior sister who was operating the ventricular mirror for the first time, Huang Zhilei was more nervous than the person involved. It was just that the emperor was not in a hurry to kill the eunuch. After the lecture on the spot, he said, "Do I need 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 remember this kind of surgical approach that she just had.

What Huang Zhilei wants to express is: "You take the ventricular mirror sheath."

This time, Xie Wanying understood the words of Senior Brother Huang. This mirror sheath feels different from the puncture needle, and is heavier than the puncture needle.

When puncture needles are punctured, the surgeon can hold a finger on it. If the puncture needle is not stable and tilted. The operation of the ventricular lens is not like this. The doctor holds the handle of the mirror sheath with both hands, just like holding the sword in both hands and inserting it into it.

I think this operation is very good at testing the stability of the doctor's hands.

"The angle is very important." Xie Wanying said.

With her words, the big guys around nodded in their eyes.

Song Xuelin handed her the ventricular lens directly.

Maybe he would hesitate about this before, so he doesn't have to hesitate anymore. Because Dr. Xie obviously had some major surgery when he came back this time.

When Xie Wanying recalled, the fairy brother was so nice to her that he didn't need to say much. How could other mentors give her such an opportunity to practice?
