Student Xie's courage was so bold that it made the hearts of a group of people feel like they were on a roller coaster and the electrocardiogram curves fluctuated violently.
After careful manipulation, the meningeal interface was successfully separated and ready to explore the nerves and blood vessels in the brain tissue.
The surgeon's eyes were closed like a blind man. Others looked at her quick and steady hands and thought: perhaps it should be said that the surgeon's eyes and soul were transferred to his hands, which operated their own cameras.
The surgical incision is very small and the bone window is small. The two slender "chopsticks" held by the surgeon are only inserted into the coin-sized opening. This situation is like inserting the "chopsticks" into the mouth of a narrow cup. toss.
The area that can be reached by the tip of the doctor's "chopsticks", such as other surgeries, is not completely limited in the size of the opening, but there is a regional limit. In minimally invasive neurosurgery, the operating range that the doctor can reach with surgical instruments should be a cone area calculated from the surgical window downwards.
It can be seen here again that it is very important for doctors or neurosurgical navigation to predict the location of the lesion during the entire operation. If the insect body exceeds this limit area, the operation will definitely fail.
As the operation progresses, the environment in the surgical field becomes more and more complex, with various brain tissues, including blood vessels and nerves, appearing. It may be a bit difficult for the surgeon to do it alone.
Ichisuke came to assist at the request of the chief surgeon.
Neurosurgery is different from other surgical procedures. For example, in the last hydrocephalus surgery, we already know that scalp retraction is more like cardiothoracic thoracotomy or spinal surgery. It is more convenient to directly fix the retractor, and the surgeon can completely free up his hands for operation.
Tofu-like brain tissue retraction usually uses brain pressure plates instead of retractors, which are somewhat similar to tongue depressor-like surgical instruments. If a nerve or blood vessel needs to be pulled, there is a special nerve retractor and blood vessel retractor. The handle is like a long chopstick and the head is hook-shaped.
Most of the surgical instruments used in microneurosurgery are long and thin, rather like dental instruments.
When senior doctors act as assistants, their technical prowess does not need to be questioned or worried by others. The timing of occasionally assisting with a brain pressure plate or a nerve retractor is called divine precision.
Before I knew it, almost an hour had passed. There is no way, neurosurgery has to be done slowly, no matter how fast it is, it cannot be done faster. This is why the operation took so long.
Finally, the surgeon's hand paused.
Others in the operating room saw the white thing through the electronic screen of the microscope's high-definition video system.
At first glance, it looks like a white rope, but anyone who studies medicine knows that it is not, but an insect.
Thinking that this thing is in the brain, some people felt nauseated on the spot.
Wei Shangquan walked out of the operating room unknowingly and touched his heart. He felt so sick.
The junior brothers and sisters in the lower grade looked pale.
The parasites we saw in medical schools were in bottles, not like the ones that are alive and wriggling in the human body today.
Before you can remove the worm, you must first peel it off where the worm may be stuck to the brain tissue. Suddenly, everyone was envious of Xie who operated with his eyes closed. At least he didn't have to open his eyes to see such disgusting things.
In Xie Wanying's brain, there was only the three-dimensional outline of the insect body, which was equivalent to an object, so she didn't feel too disgusted.
