Chapter 2843 [2843] The point is here

The length of the shunt tube needs to be measured and cut before surgery.

Hearing what he said, Song Xuelin turned his head to look at him with an unbelievable look.

There is no head-banging from Senior Brother Huang, but obviously, the gaze of the talented Beidu is even more insulting. Not saying he's stupid, but wondering if he's from an alien planet.

Student Wei instantly blushed and said, "You have something to say."

I asked how long the insertion was. You told me how long the tube was from the head to the abdomen. Is the latter inserted? The latter action is to wear. This is clearly the communication between the Earth language and the alien language.

Student Wei wanted to hold his head in his hands and ran away: Well, why did he come to the neurosurgery internship to seek abuse, and the abused person was IQ.

There is no department like neurosurgery.

No, no, no, it's just the group of terrifying Senior Brother Cao. The other groups, like Deputy Director Lu's group, are neurosurgeons, so they can be called the "idiot group" by the little idiot brother.

The length of the insertion refers to the length of the shunt tube reaching the lateral ventricle after the head is opened. The shunt pipe is connected in several sections. The highlight is definitely on the end of the pipe in the head of the starter. Because the brain is more intricate than the rest of the human body, a little mistake will be irreparable. This is what neurosurgeons do best.

Specifically, first, after this shunt enters the human brain, it must accurately reach the lateral ventricle instead of entering the brain parenchyma or other important functional areas. For this reason, the precise length of the shunt insertion must be the first priority. Second, the tip of the shunt should be placed directly in front of the interchamber hole.

The interventricular foramen is a group of tunnels connecting the left and right lateral ventricles with the third ventricle, located in the front of the lateral wall of the third ventricle. The accurate placement of the shunt tip in this position can prevent the choroid plexus and gliosis, which are two major blockages of the shunt, from blocking the side hole of the shunt.

A group of students turned back and saw the sterile and packaged shunt tube that the instrument nurse was preparing. The first time I saw it, I couldn't help but be surprised: such a thin tube?

The drainage tubes usually seen in other clinical departments are mostly thick. Thick drainage tubes have the advantage of easily draining fluid and avoiding blockages.

CSF This shunt is different. The first element of it is that it is a shunt that is to be placed in the human body for a long time. As long as nothing happens, it will not be taken out. It is long and long, with one end inside the head, the most delicate organ of the human body. Doctors must consider the comfort of the human body. It can't be said that getting a thick thing and putting such a long thing in the human body makes the patient feel uncomfortable all day long.

Shunt is a thin diameter silicone tube, both for adults and children.

So it’s better to see it once you hear it. Most of the things that are said in the textbooks are generalized, and some things are said and cannot be understood. If you need to see the real thing in the clinic, it will suddenly become dark and bright: so it is.

It is hard to imagine how difficult it is for the head of such a thin tube to fall precisely to the designated position.

The first step is to calculate the exact length.

What is calculated.

It only depends on the current films, plus the doctor's own experience and computing power. The predecessor can refer to the doctor's hand. Xie Wanying admitted that she didn't, she was definitely not as good as Senior Brother Cao, she could only rely on her own brain to do the math.

"The depth of the frontal approach is about 7.2. If it is the posterior occipital approach, it is about 10.5." Xie Wanying said.

Thank you for your support! ! Good night dears~
