The length of the shunt needs to be measured and cut before the operation.
Hearing his words, Song Xuelin turned his head and looked at him with a strange look.
There is no knocking on the head by Senior Brother Huang, but obviously, the eyes of the talented man in the northern capital are even more insulting. Not saying he is stupid, but wondering if he came from some alien planet.
Student Wei blushed instantly, and said, "Speak directly if you have something to say."
I'm asking about the length of the insertion. You tell me how long the tube from the head to the abdomen is. Is the latter an insertion? The latter action is to wear. This is clearly the communication between earth language and alien language.
Classmate Wei wanted to hug his head with his hands and run like a mouse: Well, why did I come to the neurosurgery internship to seek abuse, and the one who was abused was IQ.
There is no other department like neurosurgery.
No, no, it's Brother Cao's group that's just scary. The other groups, like Deputy Director Lu's group, are also neurosurgeons, and they can be called the stupid group by the little idiot Brother Huang.
The length of insertion refers to the length of the shunt tube reaching the lateral ventricle after the opening of the head. The shunt pipe is connected in several sections. The main event must be at the end of the pipeline in the head of the starting end. Because the brain is more intricate than the rest of the body, a little error is irreparable. This is what neurosurgeons do best.
Specifically, first, after the shunt tube 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 shunt tube insertion must be placed first. Second, the tip of the shunt tube should be placed directly in front of the interchamber hole.
The interventricular foramen is a group of holes that communicate with the left and right lateral ventricles and the third ventricle, located in the anterior part of the side wall of the third ventricle. The tip of the shunt tube is accurately placed at this position, which can prevent the side holes of the shunt tube from being blocked by the two major daily blockages of choroid plexus and gliosis.
A group of classmates turned their heads and saw the sterilized and packaged shunt tube being prepared by the equipment nurse. When I saw it for the first time, I couldn't help being surprised: such a thin tube
Most of the drainage tubes seen in other clinical departments are relatively thick. Thick drainage tube is good, it is easy to drain fluid and avoid clogging.
The cerebrospinal fluid shunt is different. Its elements are firstly that it is a shunt tube that needs 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 in the head, the most delicate organ of the human body. Doctors must consider the comfort of the human body. It cannot be said that putting a thick and long thing in the human body will make the patient feel diaphragmatic all day long.
The shunt is a thin-diameter silicone tube, whether it is an adult or a child.
So it is better to see once than to hear a hundred times. Most of the things mentioned in the textbooks are generalized, and some things cannot be understood after being said. Need to go to the clinic to see the real thing, will suddenly come to light: so it is.
It is conceivable how difficult it is for the head of such a thin tube to fall accurately to the designated position.
The first step is to calculate the exact length.
By what calculation.
It only depends on the current various films, plus the doctor's own experience and computing power. The predecessor can refer to the doctor's hand. Xie Wanying didn't think she had any, and she was definitely not as good as Senior Brother Cao, so she could only do the math with her own brain.
"The depth of the frontal access is about 7.2. If it is the retro-occipital approach, it is about 10.5." Xie Wanying said.
