In Good Luck Come's song, 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 drug's effect.

"Zheng Lao Ban, this kid is quite sensible," Lao He said, looking at the sleeping Xiao Shitou.

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

Xiao Shitou's surgical positioning had been rehearsed many times; Zheng Ren will perform neck tumor resection under interventional guidance, different from ordinary surgery.

Gao Shaojie and Lin Yuan began to get busy, while Zheng Ren didn't call anyone else; the whole surgery preparation he and Su Yun would complete themselves.

For someone at his peak level, an assistant's presence 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 for more people on the operating table.

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

Encountering a hot-tempered circulating nurse, they would immediately go berserk, pointing at the nose and cursing.

Zheng Ren stood quietly 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."

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

After positioning, Zheng Ren put on lead clothing, scrubbed up, then came back and stood steadily to the side, not stepping up to the operating table 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, and using near-infrared imaging technology during surgery could detect fluorescence in tumor tissue, making real-time visualization of intraoperative tumor lesions possible.

Initially, indocyanine green was used for hepatic 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.

Consequently, over the following years, specially designed laparoscopic surgeries using indocyanine green to label gastric cancer, esophageal cancer, etc., rapidly rolled out clinically.

Only because the molecular-targeted fluorescence probe technology lacked strong promoters, and many clinical doctors felt it was unnecessary, plus they had to change surgical habits and adopt new equipment, so the promotion of this technology has been 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, since indocyanine green itself lacks tumor targeting, from then on, targeted fluorescent molecular probes began to enter people's view.

Zheng Ren's application this time is precisely this technology, for precise tumor localization.

Moreover, he goes further than anyone else!

Normal molecular-targeted fluorescence probe technology requires administering the drug preoperatively via peripheral intravenous injection, with the drug distributing 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 the surgeon to gain a deeper understanding of the patient's condition.

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

Therefore, Zheng Ren directly decided to administer the drug via interventional approach at the external carotid artery, acting directly on the tumor in the surgical 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 precision and repeatability are much higher.

A surgery spanning three surgical departments, also requiring interventional participation, could only be done by Zheng Lao Ban leading 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.

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

This way, both Zheng Ren and Su Yun, as assistant, can clearly see the fluorescently imaged tumor tissue.

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

Zheng Ren and Su Yun wear microscopes on their heads.

Plus, before Xie Yiren lies the surgical case sent by Doctor Charles to Zheng Ren; all of this makes the surgery look like it has a fully metallic feel.

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.

Once 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 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 surgical area as the willow-leaf blade wound along, 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 the skin was cut open, the infrared camera's image on the screen showed that under infrared light, the tumor tissue appeared green and the sentinel lymph nodes slightly discolored.

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

This scene is too much black technology; it's not the usual surgical scene Lao He is familiar with.

It's somewhat unfamiliar, yet within the unfamiliarity there are hints of familiarity.

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

These things somewhat dilute the cold mechanical feeling, making it look 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 banished the assistant to one side, seriously surveying his domain—the ventilator, monitor, micro pump, etc.

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 sufficient—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 Zheng Lao Ban's considerations.
