Chapter 2970 【2970】Slender and Long

Classmate Xie's guts, enough to eat the guts of a leopard, made the hearts of a group of people feel like they were riding a roller coaster, and the electrocardiogram curves showed violent ups and downs.

Carefully dial and dial, the meningeal interface will be successfully separated in a short while, ready to explore the nerves and blood vessels in the brain tissue.

The chief surgeon's eyes are closed like a blind person, and others refer to her fast and steady hands, think about it: maybe it should be said that the chief surgeon's eyes are transferred to her hands, which 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 surgeon only extend into the opening that is as large as a coin. This situation is like "chopsticks" extending into the opening of a narrow cup. toss.

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

From this, it can be seen again that it is very important for the doctor or neurosurgical navigation to predict the location of the lesion throughout the operation. If the worm body exceeds this limit area, the operation must fail.

With the progress of the operation, the environment in the operative field area became more and more complex, and various brain tissues appeared, including blood vessels and nerves. It may be a bit difficult to dial only by the chief surgeon.

Kachisuke came to assist at the request of the chief surgeon.

Stretching in neurosurgery is different from other surgical procedures. For example, in the previous hydrocephalus surgery, it has been known that scalp stretching is more like cardiothoracic thoracotomy or spinal surgery. It is more convenient to directly fix the retractor, and the surgeon can completely free up both hands to operate.

Brain tissue stretching such as tofu is usually not a retractor, but a brain depressor, which is a bit like a spatula-like surgical instrument. If you need to pull the nerves and blood vessels, there are special nerve pullers and blood vessel pullers. The handle is also like long chopsticks, and the head is in the shape of a hook.

Most of the surgical instruments for microneurosurgery are thin and long, rather they are somewhat similar to dental instruments.

When a senior doctor is an assistant, there is no need for others to question and worry about his technical strength. Occasionally, when he goes down with a brain pressure plate or a nerve hook to assist, it is called divine precision.

Almost an hour has passed since the surgery. There is no way, neurosurgery has to pick "tofu cubes" slowly, no matter how fast it will be. This is the reason for the long operation time.

Finally, the chief knife'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 string, but everyone who studies medicine knows that it is not, it is a bug.

Reminiscing that this thing is in the brain, some people felt nauseous on the spot.

Wei Shangquan walked out of the operating room unknowingly, touching his heart, it was so disgusting.

The younger brothers and sisters in the lower grades looked pale.

The parasites seen in the medical school were soaked in bottles, unlike the ones that are alive and wriggling in the human body now.

Before taking out the worm, it has to be stripped first, and the place where the worm body may be glued to the brain tissue must be peeled off. All of a sudden, everyone envied Mr. Xie who operated with his eyes closed, at least he didn't have to open his eyes to see such a disgusting thing.

Xie Wanying's brain only had the three-dimensional outline of the worm body, which was equivalent to an object, so she didn't find it too disgusting.
