Amid the singing of good luck, Lao He held a mask and covered the mouth and nose of Xiaoshitou.

During the breathing, the small stone fell asleep under the action of the medicine.

"Boss Zheng, this kid is quite sensible." Lao He said to the sleeping little stone.

"Yes." Zheng Ren nodded, "Anaesthetize, prepare to put his posture."

Xiao Shitou's surgical position has been previewed many times. Zheng Ren has to undergo a surgery to remove a neck tumor with interventional cooperation, which is different from ordinary surgery.

Gao Shaojie and Lin Yuan started to get busy, and Zheng Ren didn't call anyone else, and prepared to complete the entire surgical operation himself and Su Yun.

For him at the peak level, the existence of an assistant is meaningful, but he needs an assistant of Su Yun's level. Moreover, he needs to undergo an radial artery and apply a local developer. There is really no more people standing on the operating table.

Lao He was busy, intubating the cannula, adjusting the ventilator's value and giving medication.

Xie Yiren was tying the number of equipment with the tour nurse. At the beginning, the equipment nurse and the tour nurse were very resistant to other people's disturbances. Once the counting was forgotten, they had to start over.

When I meet a hot-tempered tour nurse, I will run away and point at my nose and curse.

Zheng Ren stood quietly in front of the video reader, holding his arms and watching the movie for the last time.

After 12′22″, Su Yun's voice came: "Boss, stop talking, take the stage."

"Yes." Zheng Ren nodded and turned around to brush his hands.

With his posture in place, Zheng Ren went to wear a lead suit and brush his hands. When he came back, he stood steadily and did not stand next to the operating table as soon as possible.

The airtight lead door was closed, Gao Shaojie had completed the puncture, and Lin Yuan started to step on the line as an assistant to perform the super selection.

What he wants to do is inject indocyanine green into local blood vessels.

In 2009, Oriental scholar Ishizawa discovered that patients with liver tumors were injected with intravenous intravenously injected indocinol green before surgery. Intraoperatively, near-infrared imaging technology could detect fluorescence in tumor tissue, making it possible to visualize the intraoperative tumor lesions in real time.

Indocyanine green was initially used for the diagnostic treatment of liver segmentation and other liver diseases.

Over time, the surgeons found that infrared imaging could be used to check the range of tumor tissue.

So in the following years, the special laminoscopic surgical treatment methods for gastric cancer, esophageal cancer, etc. labeled with indocyanine green were quickly developed clinically.

It is just because the molecular targeted fluoroscopy technology is not effective, and many clinicians think it is not necessary. In addition, they have to change their surgical habits and apply new instruments, so the advancement of this technology is very slow.

Indocyanine green has become the only approved clinical trial. nir fluorescence has already begun to show results in applications such as liver cancer development and sentinel lymph node development. However, since indocyanine green itself does not have tumor targeting, targeted fluorescent molecular probes have begun to enter people's field of vision.

Zheng Ren used this technology this time to accurately locate tumors.

And he is walking further than everyone!

Normal molecular targeted fluoroscopy technology requires peripheral intravenous administration before surgery, and the drug is distributed to tumor tissue along with the blood circulation.

The part with tumor tissue is presented on the screen with the help of infrared fluorescence camera, allowing the surgeon to have a deeper understanding of the patient's condition.

However, Xiao Shitou's condition is worse and his body is weaker. It is meaningless to administer systemic medicine to the peripheral veins, so it will increase the burden on the liver anyway.

Therefore, Zheng Ren directly decided to intervene and administer the drug at the external carotid artery, directly acting on the tumor in the surgical area to develop it.

If you do this, the dose of the drug is given smaller. Moreover, for some insensitive developing locations, repeated administration and contrast examination can be performed. Compared with the accuracy and repeatability of intravenous administration, the accuracy and repeatability of intravenous administration are much higher.

One surgery spans three surgical departments and requires interventional participation. Only Boss Zheng, who is in the interventional treatment group, can do so.

He didn't have to coordinate the connection between departments. It would be enough to pull Gao Shaojie on stage in just one sentence.

When the interventional operation began, Zheng Ren squinted his eyes and looked at the screen.

Opposite the operator is the intervention screen, while another infrared-developed screen is hung above the side of the little stone's legs.

In this way, both Zheng Ren and Su Yun, who is an assistant, can clearly see the fluorescence-developed tumor tissue.

Almost all kinds of machines, ventilators, monitors, micro pumps, interventional development screens, and fluorescent infrared development screens are all over the entire operating table.

Zheng Ren and Su Yun were wearing microscopes on their heads.

In addition to the surgical box given to Zheng Ren by Dr. Charles in front of Xie Yiren, everything makes the operation look like a full metal texture.

This is no longer the operating room of 912, but rather it is like an operating room from the future.

Zheng Ren silently watched Gao Shaojie perform an imaging and used a high-pressure syringe to give a small amount of developer.

Zheng Ren doesn't need to do this "simple" operation himself.

After Gao Shaojie completed the operation, Zheng Ren walked to the operating table.

He first adjusted the angle of the camera with a layer of sterile plastic film outside and the angle of the shadowless lamp, then took a deep breath and reached out his hand gently.

The handle of the lancet was then slapped in Zheng Ren's palm.

The huge "S"-shaped incision appeared in the operation area as the lancet winds, with the curve flawless. After the incision was opened, Zheng Ren slapped the lancet on the side of Xiaoshi's legs. He stretched out his hand, slapped the sterile gauze and hemostatic forceps into the palm of his hand.

Su Yun held electric scavenging and hemostatic forceps in his hand to help Zheng Ren stop bleeding.

After the skin is incised, the image presented by the infrared camera on the screen is shown in the infrared light, which is green tumor tissue and slightly discolored sentinel lymph nodes.

Lao He looked at Boss Zheng surrounded by countless machines, and felt a sense of confusion in his heart.

This kind of scene is too dark and it is not the scene where Lao He is familiar with the surgeons who usually undergo surgery.

Some are strange, but there is a little familiarity in the strange.

The bleeding after the skin edge was cut, the hemostatic forceps and electric scissors in Su Yun's hand, and the blunt scissors and hemostatic gauze in Boss Zheng's hand.

All of these made the cold mechanical feeling diluted a little, and it looked a little more realistic.

Lao He took a deep breath and bulged his cheeks, so that he would not be shrouded in the sense of technology like this heavy metal frenzy.

As long as you take responsibility for your own part, you must not make mistakes!

He drove his assistant aside and looked around his territory seriously - ventilators, monitors, micro pumps, etc.

I am just a part of the medical team. It is enough to maintain myself without delaying the operation of the entire machine. This is what Lao He has positioned himself.

As for the central control equipment that is Boss Zheng, he only needs to cooperate as much as possible. As for how to do the operation and how the postoperative effect are, Boss Zheng should consider.
