Chapter 1440: with translation of chapter title

1394 Are you ready to cut it by hand?

"Praise you, Boss!" Professor Rudolf Wagner said: "The prevailing view in Europe is that optical tweezers entering clinical practice will take at least 20 years. And great you, are you now preparing to start using them?"

"Let's try, I also don't know if it will succeed." Zheng Ren said modestly.

Last night in the System Space, using nearly all of the Surgical Training Time, Zheng Ren has preliminarily mastered how to use the Optical Tweezers.

Professor Rudolf Wagner followed Zheng Ren honestly and went to the Pathology Department.

Although he is a doctor of the Interventional Medicine Discipline, he has considerable knowledge of frontier technology.

Even if it is not a surgical method but only used for diagnosis, Professor Rudolf Wagner is also very curious and wants to see how Zheng Ren operates.

Upon arriving at the Pathology Department, a faint smell of formaldehyde mixed with the smell of anhydrous alcohol hit him face-on.

The smell was faint, but Zheng Ren still furrowed his brow.

It seems I'm not suited to work in the Pathology Department; the smell here is too strong, especially the anhydrous alcohol—smelling too much might make one drunk.

Then later let the patient's family complain about working after drinking…

Zheng Ren wandered in thought, looking at the people in the Pathology Department, feeling somewhat worried.

Su Yun only gave himself a name; before his eyes, several mosaics kept moving— which one is the real one?

"Excuse me, is Director Wu Hang here?" Zheng Ren asked.

"You must be Boss Zheng." A person was looking at slides under the Microscope; hearing Zheng Ren speak, he lifted his head.

He is not tall, but his head is large, like the big-headed son in cartoons, looking somewhat disproportionate.

"Director Wu, hello, I am Zheng Ren." Zheng Ren said politely.

"Yun Ge'er and I told you, you want to come debug the machine?" Wu Hang stood up, handed over his current task to the assistant beside him, and came to Zheng Ren's side.

"Hmm, I want to try it, and also trouble you to give me a piece of tissue."

"I've prepared it for you; today's Gan Dan Wai Ke surgery is considering hepatocellular carcinoma. Are you planning to cut with the machine or by hand? Given your skill level, are you planning to cut micron-level slices directly by hand?" Wu Hang asked full of anticipation.

On the Pathology Department's slicer there are markings, generally 0-50 mm, which can be adjusted according to different specimens.

Wu Hang has heard of Zheng Ren; recently, 912 major events are all related to Zheng Ren, making it hard to not know what he's doing.

Su Yun also didn't explain in detail, only saying that Boss Zheng would come to do pathology sectioning. Wu Hang thought Zheng Ren would use a knife to cut it himself, so he was especially curious.

If surgical technique is good enough, can it truly replace the machine and produce several-millimeter-thick slices on its own?

That would be too amazing!

Wu Hang's big head swayed back and forth in front of him, making Zheng Ren feel uneasy.

"Director Wu, what are you looking for?" Zheng Ren asked.

"A knife!" Wu Hang was a little excited; every male doctor has a heart to become the best surgeon.

"Uh..."

"I heard your surgical instruments are custom-made, a blade costs $233? Why didn't you bring it? Can ordinary blades also achieve micron-level precision?" Wu Hang could hardly wait.

"That's true, but I'm not preparing to cut tissue." Zheng Ren held the Optical Tweezers equipment; Wu Hang had never seen it and didn't know what it was.

"Oh." Wu Hang felt a little disappointed.

As it turns out, Boss Zheng can't do it either.

He came to Zheng Ren's side and said, "Boss Zheng, come with me to see if the prepared tissue is suitable."

Saying that, Wu Hang brought Zheng Ren to the sampling room.

A large room of over a hundred square meters, filled with various containers.

Zheng Ren knows that the bodily tissue taken from surgery is sent by the Operating Room's circulating nurses to the Pathology Department, where it is sampled here.

That cutting board-like workbench is where the technicians take samples.

Tissue excised by surgery and waiting for pathological examination must undergo sampling, fixation, Dehydration, clearing, wax embedding, sectioning, mounting, staining, and covering— a series of steps— to remain on a glass slide for observation under the Microscope of the pathological morphology of diseased tissue.

Sampling is the first step; every day seeing those bizarrely shaped tissues and smelling formaldehyde and anhydrous alcohol, Zheng Ren feels he could never work in the Pathology Department.

Every department has its own difficulties.

Try to complete Li Lao's pathological diagnosis; after this, we should still come here less often.

"Boss Zheng, with the slicer, how many mm are you preparing?" Wu Hang asked.

"No need." Zheng Ren smiled, seeing Wu Hang put on Gloves, took out the pathology tissue prepared for Zheng Ren, then handed the Optical Tweezers to Professor Rudolf Wagner, and subsequently used tweezers to take a strand of tissue.

Wu Hang was stunned; what use is such a thread-like piece of pathology tissue? Uneven thickness, it basically cannot be stained or observed.

"Boss Zheng, what is this...?" Wu Hang asked tentatively.

"I want to test the Optical Tweezers."

"..."

What are Optical Tweezers? Wu Hang truly doesn't know. Frontier technology hasn't yet entered clinical practice; to doctors in various clinical departments, this is nothing short of Arabian Nights.

The extracted tissue was placed in a container, and Wu Hang brought Zheng Ren to the director's private room.

Inside there is a table, on which sits a brand-new Microscope.

"Boss Zheng, today we're lucky—the director is resting." Wu Hang laughed: "This Microscope is our best one, dedicated to the director, treasured; please handle it gently. If you cause any trouble, the director will come to me for trouble."

"Mm-hmm." Zheng Ren nodded repeatedly.

Probably because Wu Hang saw Zheng Ren bringing the equipment over and felt unsure, he gave that warning.

He placed the pathology tissue to the side, first glanced at the director's Microscope, understood the model, then installed the Optical Tweezers equipment onto the Microscope.

Wu Hang initially had some worries and lack of understanding.

Does the Microscope need additional components? It shouldn't! At the very least, in my over ten years of work, I've never seen such components appear.

So he was afraid that Boss Zheng would break the director's Microscope.

If this damn thing breaks, the director might kick me into the intraoperative freezing group, making me sit there for a year or two…

Just thinking about the daily ten or eight intraoperative freezes makes Wu Hang feel terrible overall.

Half an hour later, Zheng Ren finished installing the equipment.

"Boss, this is gaha." The professor looked bewildered and asked.

"Optical tweezers equipment can be installed on an ordinary microscope, then use the microscope to observe pathological tissue, and use the optical tweezers equipment to take pathological cells." Zheng Ren explained.

"Boss, this is too troublesome." Professor Rudolf Wagner said: "We don't even need to come here; even if the pathology department is unreliable, they can still do sections and such, and if worse comes to worst, we can mail the pathology slides to Heidelberg, our colleagues......"

"Fugui'er, that's not how it works." Zheng Ren smiled, "This is just a trial; if it works, we would need to perform a biopsy under CT Shi imaging to obtain pathological specimens—that's when optical tweezers would truly be used."
