Heart valve surgery, whether it is mechanical valve replacement, repair or tricuspid valve surgery, is a fourth-level surgery outside the heart and is considered a major surgery.

Judging from the medical conditions and medical technology in recent years, cardiac mitral valve repair surgery is now a relatively mature operation, and the risk of surgery is no longer too great.

Before replicating Zhang Jiahao's skills, Fang Han really didn't know much about this surgery, so he could only guess roughly how this surgery was.

As a student who graduated from the School of Traditional Chinese Medicine, Fang Han’s initial understanding of this surgery was actually not much higher than that of ordinary people.

But after replicating Zhang Jiahao's skills, Fang Han's understanding and insights on heart valves instantly reached a higher level, and he had a clearer understanding of this surgery.

The replacement and repair of heart valve surgery mainly depends on the degree of the disease and the degree of damage. This is like something that is not seriously damaged. We can repair it, but if it is severely damaged, it must be replaced.

But the heart is the most critical organ of the human body after all, and it is not something in the simple sense. If I practice it, I will change it if I can’t practice it well. This will lead to a higher risk than if I replace it directly.

As of now, heart valve surgery has traditional methods of opening the chest and intervention, whether it is replacement or repair.

The two surgeries are also aimed at different situations. To a certain extent, interventional surgery has little traumaticity, good recovery and few complications, which is a major trend in future surgical procedures.

However, for now, interventional surgery still has many limitations, and not any lesion surgery can be used for intervention. This time, Fang Han used the traditional method of opening the chest surgery for Long Yaxin.

"Dr. Fang, everything is normal." The anesthesiologist responded to Fang Han.

"Prepare for surgery!"

Fang Han raised his hand and walked to the main surgery position. As soon as he reached out, the nurse in the instrument put the scalpel in Fang Han's hand.

Long Yaxin was covered with a towel, only a small piece of fair skin was exposed at the outlet. Fang Han held a scalpel in his hand, without any hesitation, and with a light stroke, he made an incision on Long Yaxin's chest.

This time, Fang Han had many concerns about Long Yaxin's surgery, not only considering the prognosis, but also considering the beauty. After all, it is a girl, and the sutures and scars of the wounds must be considered.

So Fang Han chose small incisions as much as possible.

Looking at the incision made by Fang Han, Wang Zhicheng subconsciously asked: "Xiao Fang, is the incision too small?"

Whether it is cardiothoracic surgery or extrahepatic surgery, the size of the incision will affect the difficulty of the operation. The larger the incision, the more convenient it is for doctors to operate, the wider the field of surgery, the more places it can be observed, the smaller the incision, the less space it can operate, and the field of surgery will be limited to a certain extent.

Fang Han used a small incision and Wang Zhicheng understood that many female patients, especially some young female patients, would require small incisions during surgery. The patient is Fang Han's girlfriend, and it is understandable that Fang Han used a small incision.

No one wants his girlfriend to leave too big scars on her chest, but the incision that Fang Han chose is too small, even smaller than the conventional incision.

Wang Zhicheng had never done such a small incision before.

Generally speaking, when doing mitral valve shaping or replacement, most doctors take a central chest incision, which selects the right atrium-atrium septum route, close to the mitral valve.

This time Fang Han chose a small incision on the left ventricle, and the incision is smaller than the conventional incision.

Of course, seeing Fang Han's incision position, Wang Zhicheng no longer doubted Fang Han's level. Although Fang Han's incision is small, the available location is very good.

You should know that the patient is accompanied by a left rib fracture, this problem is also a problem that must be considered during the operation.

The heart of a normal person is located at the lower left of the middle part of the chest cavity. The heart of the human body is like a peach or a fist, and the front of the heart faces the sternum and the 2nd-6th weakness.

If this incision is not selected well, and the hook is pulled and operated at that time, if the ribs are pulled, causing the ribs that are originally well-wired to be misaligned, it will be troublesome.

The incision that Fang Han chose can be said to have completely taken into account this issue.

From this point of view, Wang Zhicheng could see that Fang Han's level in cardiothoracic surgery is definitely not low.

“The incision is enough.”

Fang Han replied softly and continued.

Qian Xiaolin stood not far away and stared at Fang Han's operation. Although it was just the beginning of the operation, Qian Xiaolin could also judge that Fang Han's level was definitely OK.

As the saying goes, experts will know if there is any.

As of now, although heart valve surgery is quite mature, many Grade 3 hospitals in China have the level of this surgery, the doctor's level is still very important.

As mentioned earlier, just to talk about general liver resection, there is no big difference between Kuang Mingzhuo and Fang Han, and there is also a subtle difference between the difference. Moreover, this premise is that you must have the same level as Kuang Mingzhuo, and Kuang Mingzhuo's level is not low.

.........

"Has the surgery begun?"

Fang Haoyang came a little late. When he arrived, Fang Han had already entered the operating room. He had just walked into the observation room next to the operating room.

In the observation room, Li Junxian, Yang Jianying and Zhang Xiaoquan were both there.

Because of Fang Han's relationship and Li Junxian knew the identities of several people, the observation room did not prohibit them from entering.

"Director Fang is here, the operation has just begun." Li Junxian hurriedly greeted.

Fang Haoyang didn't say anything and looked directly at the display screen. Fang Han was making a cut in the display screen.

"Such a small incision."

Fang Haoyang subconsciously spoke out. Although he had never had a cardiothoracic surgery, he had also participated in it. And some general surgery directors can do it, so he naturally understood what a small incision means.

"Isn't this incision small?" Zhang Xiaoquan asked back.

"It is naturally a good thing for patients to have a smaller incision, but it will increase the difficulty of the operation for doctors who perform the operation." Fang Haoyang explained.

Li Junxian also said: "Director Fang is right. Doctors abroad like large incisions very much, which is easy to operate."

Only then did Zhang Xiaoquan understand what was going on and said, "Don't worry, my master knows it. Other people's big incisions, my master's small incisions are different."
