Chapter 2970： 【2970】Slim and long

Xie's courage, which is full of leopard courage, made the hearts of a group of people experience violent ups and downs in the ECG curve as if they were riding a roller coaster.

Carefully dial, you will not succeed in separating the meningeal interface, and prepare to probe down the nerves and blood vessels in the brain tissue.

The main knife's eyes are closed like a blind man. Others refer to her fast and steady hands and think about it: Maybe it should be said that the main knife's eyes and soul are transferred to the hands, and the hands are operated by their own cameras.

The surgical incision is very small, the bone window is small, and the two slender "chopsticks" held by the main knife are only inserted into the coin-sized opening. toss.

The area that can be reached by the tip of the doctor's "chopsticks", such as other surgical operations, does not completely limit the size of the opening, but there will be an area limit. In neurosurgery minimally invasive surgery, the operating range that the doctor can reach with surgical instruments should be a conical area calculated from the operating window downward.

From here, it can be seen again that prior doctor or neurosurgery navigation is very important to predict the lesion location of the entire operation. If the worms exceed this limit, the operation will fail.

As the surgery progresses, the environment in the surgical field becomes more and more complex, and various brain tissues, including blood vessels and nerves, appear. It may be a bit difficult to dial only by the main knife.

Ichisuke assisted at the request of the chief knife.

The retraction of neurosurgery is different from other surgical procedures. For example, in the last hydrocephalus surgery, it has been known that scalp stretching is more like cardiothoracic surgery or spinal surgery. It is more convenient to directly fix the retractor, and the operator can completely free his hands to operate.

Brain tissue such as tofu is usually pulled not with a s-hook, but with a brain pressure plate, a surgical instrument similar to a tongue depressor. If the nerve and blood vessels need to be pulled, there is a special nerve retractor blood vessel retractor, the handle is also like a long chopstick, and the head is hook-shaped.

The surgical instruments for microneurosurgery are mostly slender and long, rather they are somewhat similar to dental instruments.

A senior doctor is an assistant, and his technical strength does not need to be questioned or worried by others. The occasional opportunity to use a brain platen or a nerve retractor to assist is called divine precision.

An hour has passed since the surgery. No way, neurosurgery has to pick the "bean curd" slowly, no matter how fast it is. This is the reason for the long operation time.

Finally, the chief knife's hand paused.

Other people 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 those who study medicine know that it is not, it is a bug.

Thinking that this thing is in the brain, some people felt nauseated on the spot.

Wei Shangquan unknowingly walked out of the operating room and touched his heart, so disgusting.

The younger brothers and sisters turned pale.

The parasites I saw in medical school were in a bottle, not like the ones that are crawling in the human body alive now.

Before taking out the worm, you have to do peeling first, and peel off the place where the worm may stick to the brain tissue. Suddenly, everyone envied Xie who closed his eyes, at least he didn't have to open his eyes to see such disgusting things.

Xie Wanying's brain contained only the three-dimensional outline of the worm's body, which was equivalent to an object, so she didn't feel that disgusting.
