Chapter 249 academician's doubts

In the blink of an eye, on the open optical fiber probe of magnetic tweezers, a curved blood vessel appeared, extending in all directions, in the shape of a sponge, just like a spider web blocked in the front. Without the front stereo positioning picture, we would not know where the guide wire was going to go.

The location of the capillaries, and the stereotactic image, looks a little bit off center. However, for the two authoritative experts of cardio cerebral vessels in the observation room, the reason for the deviation is that multiple cavernous vessels overlap with each other, resulting in an error in the plane graph.

However, this is also the most common problem in minimally invasive surgery. There are some errors in the plane graphics, which need rich experience to distinguish. What's more, we need a kind of finger to control the catheter in our hands and move forward to the lesion.

Although minimally invasive surgery does little harm to the human body, its biggest disadvantage is that the field of vision is small, and auxiliary imaging equipment is needed to draw a plan to guide the operation to continue. The pipe shown in the picture is never planar, but three-dimensional.

In just a few words, another screen appeared the three-dimensional structure of the patient's cerebral blood vessels constructed by the computer. Chen Qun looks at it with affectation, but he doesn't really pay attention to it. Compared with this crude and erroneous model, it has the right structure in the system, which is exactly the same. Plus practice for hundreds of times, it's almost familiar.

The optical tweezers slowly swam to a slightly enlarged part of hemangioma in front. The optical tweezers immediately emitted a blue-green cesium light, shining between the vascular walls, and began to cut at the cellular level. Although it was not a sesame sized hemangioma, it was like a big mound of earth stacked in front of it at the cellular level.

Chen Qun turned on the power of the optical tweezers to 85%, and began to grab and cut cells on the wall of capillary hemangioma. The process is boring and simple. But for Gu Ning, who often sees him in surgery, and the two academicians outside, he immediately discovers the subtle difference of his surgery.

Compared with the usual, his interventional surgery has almost become impeccable, without a redundant action. Even the optical tweezers that grab cells, they also adopt a way of mesh cutting, rather than cutting along a thin line.

As a leading cardiovascular figure, Yang Xiaoquan immediately understood Chen Qun's plan. For the relatively thick capillaries in front of him, he used the method of combining the light tweezers to grab cells and the puncture and cutting mode of interventional surgery, saving time and ensuring that the cut capillary wall can be separated from the normal interventional catheter.

Sure enough, when the cutting points of each pin line are circled, the sharp tip of the guide wire is slightly circled along the pin line, and a piece of diseased blood vessel wall immediately peels off and is put into the catheter by the guide wire. Then a small section of artificial capillary wall appeared from the catheter, and immediately filled the lesion position, and a small capillary anastomosis was performed.

The whole process took more than 30 minutes to complete the repair quickly.

Gu Ning, an assistant, or a group of professors and academicians from the cerebrovascular department outside, couldn't help looking at everything in front of him.

Let's not talk about Chen Qun's meticulous micro manipulation, which is to treat cerebral capillaries as colonoscopic surgery. Even Chen Qun's speed is faster than ordinary colonoscopic surgery.

"Lower left 30 degrees, advance 3 cm into the next hemangioma!"

Yang Xiaoquan, who served as a guide outside, was also a little happy to see Chen Qun make a good start as soon as he came up. He was most afraid that when the catheter entered the blood vessel, he could not find the location of the lesion or failed the first operation, which would have a great impact on the back. A good beginning is always more inspiring than a bad one.

Through the three-dimensional model on the screen and the blood flow in the front view, the experienced Yang Xiaoquan immediately judged that there was a blood vessel flowing to the nearest second lesion site, instead of the situation that there was no way to pass as shown in the original picture, and immediately directed Chen Qun to move down.

As soon as the words were finished, Chen Qun finished the artificial blood vessel anastomosis, and he circled the catheter half a circle, following a capillary which was somewhat like a spiral corridor, instead of passing towards the nearest one.

Yang Koizumi was about to give a warning, but he immediately held back. When the operation, the most taboo opinion is not unified, only after the beginning of the operator asked to change the way. Now Xiao Chen's action is very gentle, even if there is a little situation in front of him, he will return immediately, not to waste time, and not to puncture the blood vessel wall.

Before Yang Koizumi's idea was finished, he saw that the 3D model on the screen immediately corrected the image through all kinds of image data transmitted in real time. On the screen, a staircase with more than one circle of curvature appeared and entered the open blood vessel below. However, the blood vessel that he saw just now, which was directly connected to the lower part, was bent aside and led to another direction.What's the matter? Do you think you're too old to see?

Yang Xiaoquan felt puzzled. In this case, everyone would choose the blood vessel that fell directly instead of the curved branch road. Is Xiao Chen unlucky enough to find the right direction by picking any one?

In particular, his technique is so skillful that there is no delay at all. It should be a matter of heart rather than luck. What on earth did he use to judge whether the two vessels were right or wrong?

However, compared with the whole scheme designed by him, all this seems to be insignificant. I thought that the mandible repair operation was designed by a doctor of pathology who was studying in the city. He just performed it. Now it seems that this operation should be his own imagination with unconstrained thinking.

It's just that the treatment of two or three places is completely different from the plan he handed in in advance. Instead, he can act according to the circumstances and revise his own plan more reasonably anytime and anywhere. It's absolutely not conformist.

In this way, the situation of revising one's own plan usually only happens after the operation, or after the extremely rich experience, usually only the chief physician can do it, rather than a young man who has the eye experience to change his own operation at will.

Chen Qun's scope of talent is far beyond the most popular saying in the hospital. He only needs to see any operation once, and practice it once on the spot to master it completely.

He started to improve before he finished his practice.

Even if he is the kind of genius who only appeared in hundreds of years or nearly a thousand years, he can not have such rich experience. After the operation, I'd like to ask.

Of course, Yang Koizumi does not know that Chen Qun's surgical ability has been improved because he has just upgraded his surgical technique to the primary level and obtained the certification of a systematic Venus.
