The length of the shunt needs to be measured and cut before surgery.
Hearing his words, Song Xuelin turned his head and looked at him with an incredible look.
There was no knock on the head from Senior Brother Huang, but obviously, the look in the Beidu Talent's eyes was more insulting. It was not that he was stupid, but that he was wondering if he came from some alien planet.
Student Wei's face instantly turned red and he said, "If you have something to say, just say it."
I'm asking about how long the insertion is. Can you tell me how long the tube is from the head to the abdomen? Is the latter inserting? The action of the latter 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: Well, why did he come to the neurosurgery internship to seek abuse, and the one who was abused was his IQ.
There is no department like neurosurgery.
No, no, no, it’s just Senior Brother Cao’s team that is scary. Other teams, like Deputy Director Lu’s team, are all neurosurgeons, so they can be called the stupid team by the little idiot Senior Brother Huang.
The length of insertion refers to the length of the shunt tube to the lateral ventricle after the hole is opened in the head. The shunt tube is divided into several sections to connect. The highlight must be at the starting end of the tube in the head. Because the brain is smaller than other parts of the human body
It is more complicated and a little mistake will be irreparable. This is the scope of business that neurosurgeons are best at.
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 by mistake. For this reason, controlling the precise length of the shunt insertion must be placed first.
First. Second, the tip of the shunt tube should be placed directly in front of the interventricular orifice.
The interventricular foramen is a bunch of holes that connect the left and right lateral ventricles to the third ventricle. It is located in the front of the lateral wall of the third ventricle. Accurately placing the tip of the shunt tube at this position can avoid the choroid plexus and gliosis, two daily blockages.
The blockage blocks the side hole of the shunt pipe.
A group of classmates turned around and saw the sterilized and packaged shunt tubes that the equipment nurse was preparing. Seeing it for the first time, they couldn't help but be surprised: Such a thin tube?
Most of the drainage tubes commonly seen in other clinical departments are relatively thick. Thick drainage tubes have the advantage of easily draining fluid and avoiding blockage.
The cerebrospinal fluid shunt is different. Its first factor is that it is a shunt that needs to be placed in the human body for a long time. It will not be taken out as long as nothing happens. It is long and has one end at the most delicate part of the human body.
Organs are inside the brain. Doctors must consider the comfort of the human body. They cannot put a thick and long thing in the human body to make the patient feel diaphragm all day long.
The shunt tube is a silicone tube with a thin diameter, suitable for both adults and children.
Therefore, it is better to hear a hundred times than to see it once. Most of the things mentioned in textbooks are general, and some things cannot be understood even after being explained. When you see the real thing in clinical practice, you will suddenly understand: So that's it.
You can imagine how difficult it is to accurately position the head of such a thin tube at the designated position.
The first step is to calculate the exact length.
By what calculation?
She only relies on various current films, plus the doctor's own experience and calculation ability. The predecessor can refer to the doctor's touch. Xie Wanying thinks that she doesn't have it 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 posterior occipital approach, it is about 10.5." Xie Wanying said.
