The length of the shunt tube needs to be measured and cut before surgery.
Hearing what he said, Song Xuelin turned his head and looked at him with an incredible look.
There was no knock on the head like Senior Brother Huang, but obviously, the look in Beidu Caizi's eyes was more insulting. He was not saying that he was stupid, but wondering if he came from an alien planet.
Student Wei's face instantly turned red, and he said, "If you have something to say, just say it."
I asked how long it was inserted, and you told me how long the tube from the head to the abdomen was. Is the latter an insertion? The latter's action is penetration. This is clearly a communication between Earth language and alien language.
Student Wei wanted to hold his head with both hands and run away: Why did I come to the neurosurgery department for internship to be abused, and the one being abused is my IQ.
There is no department like neurosurgery.
No, no, no, it's only Brother Cao's group that's scary. Other groups, like Deputy Director Lu's group, are also neurosurgeons, and can all be called stupid groups by the stupid Brother Huang.
The length of insertion refers to the length of the shunt tube that reaches the lateral ventricle after the hole in the brain is opened. The shunt tube is connected in several sections. The highlight is definitely the end of the tube in the brain at the starting point. Because the brain is more complicated than other parts of the human body, any mistake will be irreparable. This is the area of business that neurosurgeons are best at.

Specifically, first, after the shunt enters the human brain, it must accurately reach the lateral ventricle instead of mistakenly entering the brain substance or other important functional areas. To this end, the precise length of the shunt insertion must be controlled first. Second, the tip of the shunt must be placed in front of the interventricular foramen.
The interventricular foramen is a group of channels connecting the left and right lateral ventricles with the third ventricle, located in the front of the lateral wall of the third ventricle. Placing the tip of the shunt tube accurately in this position can prevent the choroid plexus and glial hyperplasia, two common blockages of the tube, from blocking the side holes of the shunt tube.
A group of students turned around and saw the sterilized and packaged shunt tubes that the instrument nurse was preparing. Seeing it for the first time, they were surprised: Such a thin tube?
The drainage tubes usually seen in other clinical departments are mostly thicker. Thick drainage tubes have the advantage of being easy to drain the blood and avoid blockage.
The shunt for cerebrospinal fluid is different. First of all, it is a shunt that is placed in the human body for a long time. It will not be removed unless something happens. It is very long, and one end is in the brain, the most delicate organ in the human body. Doctors must consider the comfort of the human body. It is not right to put such a thick and long thing in the human body and make the patient feel uncomfortable all day long.
The shunt is a thin diameter silicone tube that can be used for both adults and children.
So seeing is believing. Most of the things in textbooks are general and some of them are hard to understand even if they are explained. You need to go to the real place and see the real thing, and then you will suddenly understand: So that's how it is.
You can imagine how difficult it is to get the head of such a thin tube to fall accurately into the designated position.
The first step is to calculate the exact length.
On what basis is the calculation made?
Only rely on the current various films, plus the doctor's own experience and calculation ability. The predecessor can refer to the doctor's touch. Xie Wanying admits that she has no experience and is definitely not as good as Brother Cao, so she can only rely on her own brain to calculate.
"For the frontal approach, the depth is about 7.2. If it is the occipital approach, it is about 10.5." Xie Wanying said.
