In the song of Good Luck Come, Lao He held a mask and placed it over Xiao Shitou's mouth and nose.

Between breaths, Xiao Shitou fell into a deep sleep under the effect of the medicine.

"Zheng Lao Ban, this child is quite sensible." Lao He looked at the sleeping Xiao Shitou and said.

"Hmm." Zheng Ren nodded, "Anesthesia, prepare the positioning."

Xiao Shitou's surgical position had been rehearsed many times; Zheng Ren would perform a neck tumor resection under interventional guidance, which differs from ordinary surgery.

Gao Shaojie and Lin Yuan began to get busy, while Zheng Ren didn't call anyone else; the entire surgical preparation was to be completed by himself and Su Yun.

For someone at his peak level, the presence of an assistant is meaningful, but he needs an assistant of Su Yun's caliber. Moreover, they need to go through the radial artery for angiography and locally inject contrast agent; there really isn't room on the operating table for more people.

Lao He was busy, intubating, adjusting the ventilator's settings, and administering medication.

Xie Yiren was quietly counting instruments with the circulating nurse; at the beginning, the instrument nurse and circulating nurse resisted others' interruptions. If the count was forgotten, they had to start over.

If they encountered a hot-tempered circulating nurse, they would immediately flare up, pointing at the nose and cursing.

Zheng Ren stood silently before the viewbox, arms crossed, taking one last look at the images.

After 12'22", Su Yun's voice came: "Boss, stop looking, scrub up and go on stage."

"Hmm." Zheng Ren nodded, turned and went to scrub up.

After positioning, Zheng Ren put on the lead clothing, scrubbed up, then came back and stood steadily to the side, not stepping onto the operating table at the First Time.

The airtight lead door closed; Gao Shaojie had completed the puncture, and Lin Yuan, as assistant, began to press the pedal, performing super-selective.

What he was going to do was inject indocyanine green locally into the blood vessel.

In 2009, Oriental scholar Ishizawa discovered that preoperative intravenous injection of indocyanine green in liver tumor patients, combined with intraoperative near-infrared imaging technology, could detect fluorescence in tumor tissue, making real-time visualization of intraoperative tumor lesions possible.

Initially, indocyanine green was used for liver segmentation and diagnostic therapy of other liver diseases.

Over time, surgeons discovered they could use infrared imaging technology to examine the extent of tumor tissue.

Thus, in the following years, a specially crafted laparoscopic approach using indocyanine green to label gastric cancer, esophageal cancer, etc., rapidly unfolded in clinical practice.

It was only because the molecular-targeted fluorescence probe technology lacked strong promoters, and many clinical doctors felt it was unnecessary, plus changing surgical habits and adopting new equipment were required, so the promotion of this technology was slow.

Indocyanine green has been the sole NIR fluorescence agent approved for clinical use, showing initial efficacy in applications such as liver cancer imaging and sentinel lymph node imaging. However, because indocyanine green itself lacks tumor targeting, from then on, targeted fluorescent molecular probes began to enter people's view.

This time, Zheng Ren applied this technology, precisely localizing the tumor.

Moreover, he went further than anyone else!

Normal molecular-targeted fluorescence probe technology requires administering the drug preoperatively via peripheral intravenous injection, allowing the drug to distribute to tumor tissue via blood circulation.

With the help of an infrared fluorescence camera, the parts with tumor tissue are displayed on the screen, allowing surgeons to gain a deeper understanding of the patient's condition.

However, Xiao Shitou's condition was more severe, his body weaker; administering the drug via peripheral intravenous injection throughout the body was meaningless and would only increase the liver burden.

Therefore, Zheng Ren directly decided to administer the drug via intervention at the external carotid artery, acting directly on the tumor in the operative area to make it fluoresce.

Doing this reduces the drug dosage. Moreover, for some less sensitive imaging sites, the drug can be re-administered and imaging repeated. Compared to intravenous injection, the accuracy and repeatability are much higher.

A surgery spanning three surgical departments, also requiring interventional participation, could only be done by Zheng Lao Ban, who leads the interventional treatment team.

He doesn't need to coordinate between departments; just a word, pulling Gao Shaojie onto the stage is enough.

The interventional surgery began; Zheng Ren narrowed his eyes at the screen.

Opposite the surgeon is the interventional screen, while another infrared imaging screen is suspended above Xiao Shitou's leg side.

That way, whether it's Zheng Ren or Su Yun as assistant, they can clearly see the fluorescently imaged tumor tissue.

Almost all kinds of machines surrounded the operating table: ventilator, monitor, micro pump, interventional imaging screen, fluorescence infrared imaging screen.

Zheng Ren and Su Yun wore microscopes on their heads.

Plus, the surgery box sent by Doctor Charles to Zheng Ren, placed before Xie Yiren, made the whole operation look like it had a fully metallic texture.

This is no longer the 912 operating room; rather, it resembles a future Shujian.

Zheng Ren silently watched Gao Shaojie perform angiography and inject a small amount of contrast agent with a high-pressure syringe.

This kind of 'simple' operation doesn't even require Zheng Ren to do it himself.

After Gao Shaojie finished the operation, Zheng Ren walked to the front of the operating table.

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

The handle of the willow-leaf blade immediately slapped into Zheng Ren's palm.

A huge 'S'-shaped incision appeared in the operative area as the willow-leaf blade wound its way, the curve perfect and flawless. After cutting, Zheng Ren slapped the willow-leaf blade onto Xiao Shitou's leg side. He reached out, and sterile gauze and hemostatic forceps slapped into his palm.

Su Yun held electrocautery and hemostatic forceps, assisting Zheng Ren in hemostasis.

After cutting the skin, the infrared camera's image on the screen showed green tumor tissue and slightly discolored sentinel lymph nodes under infrared.

Lao He looked at Zheng Lao Ban surrounded by countless machines, and a feeling of wistfulness arose in his heart.

This scene was too much black technology, not the usual surgical scene familiar to Lao He.

Somewhat unfamiliar, yet within the unfamiliarity lay hints of familiarity.

The bleeding from the skin edge, Su Yun's hemostatic forceps and electrocautery in hand, and Zheng Lao Ban's blunt scissors and sterile gauze in hand.

These made the cold mechanical feeling slightly diluted, looking a bit more realistic.

Lao He took a deep breath, puffed his cheeks, to keep himself from being overwhelmed by this heavy-metal-like technological surge.

As long as I take care of my own part well, that's enough; absolutely no mistakes allowed!

He chased the assistant aside, seriously surveying his own domain—the ventilator, monitor, micro pump, and so on.

I am merely a component of the medical team; as long as I maintain myself well and don't hinder the operation of the whole machine, that's enough—this is Lao He's positioning for himself.

As for the central control equipment, it's Zheng Lao Ban; I just need to cooperate as much as possible. As for how the surgery is performed and the postoperative outcome, those are all things Zheng Lao Ban should consider.
