Focusing only on her own scalpel, Xie Wanying held the scalpel again and made a cross-cut incision on the dura mater exposed after drilling.
After cutting, continue to carefully clean up all kinds of 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 plan to take the instrument to poke the inside out himself.
Looking at the incision, the doctor's field of vision is occupied by a white, soft thing, obviously brain tissue.
I used to sew tofu on the outside of the liver and gallbladder, saying that it was the work of neurosurgery. I saw with my own eyes that the shape of the brain tissue was really like a block of tofu.
The characteristic of tofu is that it is soft and easy to break into pieces. The surface forms a self-tension layer like a layer of film to maintain its own shape. Brain tissue is really something like this. If we really look into the details, the special structures such as the walking arteries and veins in the human brain and the ventricles cannot be generalized as tofu. When the brain puncture needle is launched, the doctor needs to calm down this time, after all, it is a critical step, and then ask the assistant to help estimate whether it is in this position to enter the ventricle by visual inspection or if you are not confident.
Holding the puncture needle in hand, the main surgeon must accurately determine the direction of the puncture needle, which is towards the midpoint of the line connecting the two outer ears. Be very careful about the depth of penetration, and don't pierce the arachnoid. According to the previous calculation by the chief surgeon, the length of the catheter at the brain end of the shunt is almost the same as seven.
In view of the tissue similar to tofu cubes, insert slowly and steadily when puncturing to avoid excessive damage. During this period, Xie Wanying seized the opportunity to accumulate experience. In fact, she did it once before, when she helped Teacher Xin.
After the puncture, it is the turn of the ventriculoscope.
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 ventricle is mirrored like the puncture needle, put the mirror sheath first, and enter along the original approach of the puncture needle.
Huang Zhilei was a little more nervous than the other party when explaining this to the junior sister who was operating the ventriculoscope for the first time. It can be said that the emperor is not in a hurry to kill the eunuch. After the lecture, he said: "Do you need me to demonstrate it to you first?"
"Go the same way, right?" Xie Wanying asked.
As long as she enters by the same way, she doesn't need to worry about her self-feeling. She definitely remembered this kind of surgical approach just done.
What Huang Zhilei wanted to express was: "You take off the sheath of the ventriculoscope."
This time, Xie Wanying understood Brother Huang's words. The mirror sheath feels different from the puncture needle, and is heavier than the puncture needle.
When the puncture needle is punctured, the operator can use a finger to support the stent to prevent the puncture needle from being unstable and skewed. This is no longer the case with ventriculoscopy. The doctor holds the handle of the mirror sheath with both hands, just like holding the end of a sword with both hands and inserting it into it.
This kind of operation, everyone knows, is a test of the stability of the doctor's hands.
"The angle is very important." Xie Wanying said.
With her words, the big brothers around nodded their heads.
Song Xuelin handed her the ventriculoscope directly.
Maybe he would have hesitated about this before, but now he doesn't have to hesitate anymore. Because Dr. Xie had obviously practiced major surgery somewhere when he came back this trip.
Xie Wanying recalled that Brother Shenxian was so kind to her that needless to say. How could other mentors give her such a chance to practice.
