Chapter 249 The academician's doubts

In the blink of an eye, a crooked blood vessel appeared on the opened magnetic tweezers fiber optic probe, extending in all directions in the shape of a sponge, blocking the front like a spider web. Where does Silk go from here?

The position of the capillaries, and the stereotaxic image, look slightly offset.But for the two authoritative experts and academicians in the cardiovascular and cerebrovascular departments in the observation room, they immediately recognized the reason for the deviation, that is, multiple spongy blood vessels were superimposed on each other, resulting in an error in the plane graphics.

However, this is also the most likely problem in minimally invasive surgery. There are certain errors in the plane graphics, which require rich experience to distinguish.More importantly, a finger like an arm is needed to control the catheter in the hand and advance to the lesion.

Although minimally invasive surgery does little damage to the human body, the biggest drawback is the small field of view, which requires auxiliary imaging equipment to draw a plan to guide the operation to continue.A pipe shown on the picture is never flat, but three-dimensional.

In just a few words, another three-dimensional structure of the patient's brain blood vessels constructed by a computer appeared on another screen.Chen Qun pretended to glance at it, but didn't really pay attention.Compared with this crude model with many mistakes, it has the correct structure in the system, which is not a little bit different.Coupled with the practice hundreds of times, it can almost be said to be familiar with the road.

The optical tweezers slowly walked to a slightly enlarged hemangioma in front, and the optical tweezers immediately emitted a blue-green light, shining on the wall of the blood vessel, and began to cut at the cell level, even though it was a blood vessel not the size of a sesame seed. tumor, but at the cellular level, it is like a big mound of soil, piled up in front.

Chen Qun turned the power of the optical tweezers to 80.00% and began to grab and cut the cells on the capillary hemangioma wall.The process is boring and simple.But for Gu Ning, who often saw him undergo surgery, and the two academicians outside, they immediately noticed the subtle differences in his surgery.

Compared with usual, his interventional surgery has become almost impeccable, there is not a single redundant movement, even the optical tweezers for grabbing cells adopt a mesh cutting method instead of following a thin line. Full cut.

As a cardiovascular figure, Yang Xiaoquan immediately understood Chen Qun's plan. For the relatively thick capillaries in front of him, he used a method that combines optical tweezers to capture cells with the puncture and cutting mode of interventional surgery. , while saving time, it also ensures that the cut capillary walls can be separated by normal interventional catheters.

Sure enough, when the cutting points of each stitch line circled around, the sharp tip of the guide wire slightly circled and stroked along the stitch line, and a piece of diseased blood vessel wall immediately peeled off and was taken into the catheter by the guide wire.Then a small piece of artificial capillary wall emerges from the catheter and immediately fills the lesion, performing a small capillary anastomosis.

The whole process took more than 30 minutes, and the repair was completed quickly.

Whether it was Gu Ning, who was acting as an assistant, or a group of professors and academicians from the cerebrovascular department outside, they couldn't help opening their eyes wide, looking at everything in front of them in disbelief.

Not to mention Chen Qun's various meticulous micro-manipulations, it is simply to treat the brain capillaries as a colonoscopy operation, and even Chen Qun's speed is faster than ordinary colonoscopy operations.

"At an angle of [-] degrees to the lower left, advance three centimeters to enter the next hemangioma!"

Yang Xiaoquan, who was acting as a guide outside, was also a little happy when he saw that Chen Qun made a good start as soon as he came up. He was most afraid that after the catheter entered the blood vessel, the location of the lesion could not be found or the first operation failed, which would cause great harm to the future Impact.A good start is always more inspiring than a bad one.

Experienced Yang Xiaoquan immediately judged that there is a blood vessel flowing to the second nearest lesion through the three-dimensional model on the screen, coupled with the blood flow in the front view, instead of the one shown in the original picture. When there was no way to go, Chen Qun was immediately directed to go down.

As soon as he finished speaking, he saw that Chen Qun had just completed the anastomosis of the artificial blood vessel, so he made a half circle around the catheter and went down a capillary that looked like a spiral corridor instead of going to the nearest other blood vessel.

Yang Xiaoquan was about to speak out to remind him, but he held back immediately.During the operation, the most taboo is disagreement, and the operator is required to change the method after the start.Now Xiao Chen's movements are very gentle, even if something happens in front of him, he will immediately retreat without wasting time, let alone puncturing the blood vessel wall.

Just before Yang Xiaoquan had a thought, he saw that the [-]D model on the screen had been corrected by various image data transmitted in real time, and a staircase that curved more than a circle appeared on the screen, entering the open space below. The blood vessel, and the blood vessel that he saw just now that went straight down, bends aside and leads to another direction.

What is going on?Could it be that I am old and have made a mistake?
Yang Xiaoquan was suddenly puzzled. In this case, no matter who the blood vessel is, he would choose the blood vessel directly falling instead of the curved side road next to it.Could it be that Xiao Chen's luck is against the sky, and he can find the right direction by choosing one at random?
Especially seeing that his technique is so proficient, without any delay, it should be due to his intentions, not just luck.What exactly does he use to judge whether the two blood vessels are right or wrong?

However, all of this seemed insignificant compared to the whole plan he had designed.I originally thought that the mandible repair surgery was designed by their doctor of pathology who was studying in the city, and he just carried it out.Now it seems that this operation should be conceived by himself with his unconstrained thinking.

It's just that the handling of two or three places just now is completely different from the plan he handed in in advance. Instead, he plays by ear, and can make more reasonable revisions to the plan he has formed anytime, anywhere, and is definitely not sticking to the rules.

This kind of modification of one's own plan usually only happens after the operation, or after the experience is extremely rich, usually only the chief physician can do it, not a young man who has such vision experience and makes random changes to his operation .

The scope of Chen Qun's genius far exceeds the most widely circulated saying in the hospital. He only needs to read about any operation once, and he can fully master it after practicing it on the spot.

He started to improve before he finished practicing.

Even if he is the kind of peerless genius who only appears once in hundreds of years or nearly a thousand years, it is impossible to have such a wealth of experience.After the operation is completed, it is better to inquire about it.

Of course, Yang Xiaoquan didn't know that Chen Qun's surgical ability had improved because he had just upgraded his technique to the basic level and received a gold star certification from the system.
