BXBX NOVEL Chapter 2853: 【2853】Advantage
The problem is that since ventriculoscopy is used, a well-meaning doctor will examine the patient's lateral ventricle to see if there are other problems in the patient's ventricular system.
This patient was suspected of traffic cerebral obstruction before, is this true, or the CT and other preoperative examinations failed to show anything. The accuracy of CT in this era is not very high, which has been mentioned in previous cases.
The ventriculoscopes used by doctors now are hard mirrors not soft mirrors. The doctor looks at the ventricle more comprehensively, and can replace it with an angled mirror. Pull out the ventriculoscope, change the head, put on the 30-degree lens, and reinsert it.
Once born and cooked twice, when Xie Wanying rotates the camera 30 degrees, her hands are more stable, and there is nothing to be afraid of.
The original lens was only looking straight ahead, and the angled lens was replaced, and then moved back a little. When rotating, you could see the wall of the dome-shaped lateral ventricle.
The overall shape of the lateral ventricle is something that medical students have seen in the school's anatomy classroom. It is like an orifice, but it is not a regular shape such as a perfect circle. It is a bit like a strange-shaped cave.
There are many similar cavities in the human body, like the trachea and the digestive tract, but most people don’t think that there are such cavities in the human brain. And this profound experience is difficult for medical students to realize in the anatomy room. In the dissection room, there are dead objects, not living creatures, unlike in the operating room where you can witness the life phenomenon in the cavity with your own eyes. For example, today's monitor screens can see the flow of cerebrospinal fluid in the patient's brain in the ventricle.
After checking the lateral ventricle, further check the third ventricle. This time the lens is going through the chamber hole. The first operation can be said to be completely inexperienced in this area, but fortunately I used a hard mirror. For the mobile operation of the hard mirror, the main action for the surgeon is to insert or retreat. The tube is not like a snake like a soft mirror, which is difficult for the doctor to control. At this time, as long as you enter slowly and slowly, according to the super turtle speed displayed on the monitoring screen, there will be basically no accidents. There is not much difference between the novice and the veteran at this point.
After doing this, Xie Wanying realized why Senior Brother Cao asked her to try hard mirrors first.
Hard mirrors are said to be more likely to puncture the tissue in manual operation. In fact, as long as the operator has mastered the upper limit of strength and is cautious, it is far easier to do than soft mirrors.
From this point of view, Brother Cao may be more able to lead students than Brother Tao, and he is a hidden gold medal leader.
She was not alone in thinking this way.
The group of people from Puwai Er who were watching, after all, laparoscopy is also a hard rod, and they understood something the same. They glanced at Cao Yong: This person pretends to be serious on the surface, but he is actually taking care of someone in a different way.
Back to the surgery, the hard mirror seems to be full of advantages, it seems to be very friendly to the doctor, and it can make the doctor easy to use. Why invent soft mirrors, isn't it better to use hard mirrors directly?
Hard mirrors have flaws. For example, for the first hard injury, the surgical incision is particularly important and must be accurate if a hard mirror is placed. If the direction of entering the lateral ventricle is wrong, it is difficult to pass through the interventricular foramen and enter the third ventricle to continue the examination operation.
The second hard injury is more deadly for hard mirrors. After entering the third ventricle, using a hard lens, it will be found that no matter how many angles of the lens are changed, it is impossible to pass through the midbrain aqueduct.
