Student Xie's courage was so courageous 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, and the hands were equipped with their own cameras to operate.
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 touched by the tip of the doctor's "chopsticks", such as other surgical operations, will not be completely limited in the size of the opening, but there will be a regional limit. In minimally invasive neurosurgery, it can be touched by the doctor with surgical instruments
The operating range should be a cone area calculated from the surgical window extending downward.
From here we can see again that it is very important for doctors or neurosurgery navigation to predict the location of the lesion during the entire operation in advance. If the parasite 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 appearing, including blood vessels and nerves. It may be a bit difficult for the surgeon to do it alone.
Ichisuke came to assist according to the request of the chief surgeon.
The traction in neurosurgery is different from other surgeries. For example, in the last hydrocephalus surgery, we already know that scalp traction is more like extracardiothoracic thoracotomy or spinal surgery, and it is more convenient to directly fix the retractor.
The operator can completely free his hands for operation.
The tofu-like retraction of brain tissue usually uses not S retractors, but brain pressure plates, which are somewhat similar to tongue depressor-like surgical instruments. If nerves and blood vessels need to be pulled, there are special nerve retractors and blood vessel retractors, and the handles are like
Long chopsticks with hook-shaped heads.
Most of the surgical instruments used in microneurosurgery are long and thin, rather they are somewhat similar to 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.
Unknowingly, almost an hour has passed since the operation. There is no way to do it. Neurosurgery has to be done slowly. No matter how fast it is, it cannot be done faster. This is why the operation takes 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 without knowing it. He felt his heart and felt so sick.
The junior brothers and sisters in the lower grades 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 take out the bug, you must first peel it off, peeling off the places where the bug body may be stuck to the brain tissue. Suddenly, everyone envied Mr.
.
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.
