"Praise you, boss!" Professor Rudolf Wagner said: "It is now common in Europe that it will take at least 20 years to enter the clinical practice of optical tweezers. And the great ones are ready to start using them now?"

"Try it, I don't know if it will be successful." Zheng Ren said "humblely".

Last night, almost all the surgical training time was spent in the system space, and Zheng Ren had already mastered the use of optical tweezers.

The professor followed Zheng Ren honestly and went to the pathology department.

Although he is an interventional doctor, he has a considerable understanding of cutting-edge technology.

Even if it is not a surgical method and is only used for diagnosis, the professor is very curious and wants to see how Zheng Ren operates.

When I arrived at the pathology department, a faint formalin smell mixed with the smell of unhydrated alcohol came towards me.

The taste was very light, and Zheng Ren still frowned.

It seems that I am not suitable for working in a pathology department. The smell here is too strong. Especially for anhydrous alcohol, you will get drunk if you smell too much.

Then let the patient's family complain about taking up work after drinking...

Zheng Ren was thinking a lot and was a little worried when he looked at the people in the pathology department.

Su Yun only gave himself a name, and more than a dozen mosaics were constantly moving. Which one was it?

"Where is Mr. Wu Hang and Mr. Wu?" Zheng Ren asked.

"Boss Zheng, right?" A man was watching a movie in front of a microscope. Hearing Zheng Ren talk, he raised his head.

He is not tall, but his head is very big, like the big-headed son in the cartoon, looking a little dissonant.

"Hello, Mr. Wu, I am Zheng Ren." Zheng Ren said politely.

"Brother Yun told me that you want to debug the machine?" Wu Hang stood up, gave the work at hand to the assistant next to him, and came to Zheng Ren.

"Well, I want to try it, and I'd like to ask you to organize it."

"I'm ready for you. Today's hepatobiliary surgery is considered hepatocellular liver cancer. Are you planning to cut it with a machine or manually? At your level, are you planning to cut micron-level slices directly with your hands?" Wu Hang asked expectantly.

There are scales on the sectioning machine of the pathology department, usually 0-50m, which can be adjusted according to different specimens.

Wu Hang has heard of Zheng Ren. The recent 912 major events have been related to Zheng Ren, and it is difficult for him to know whether he is.

Su Yun didn't say it carefully, just said that Boss Zheng was coming to do the pathological section. Wu Hang thought Zheng Ren was going to cut it himself with a knife, so he was very curious.

If the surgery is done well, can it really replace the machine to make several m-thin slices?

That's amazing!

Wu Hang's big head was shaking in front of him, making Zheng Ren feel uncomfortable.

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

"A knife!" Wu Hang was a little excited. Every male doctor had a heart to become the best surgeon.

"Well……"

"I heard that the surgical instrument you used is specially made, one blade is $233? Why didn't you carry it? Can ordinary blades also achieve micron level accuracy?" Wu Hang couldn't wait.

"The words are right, but I'm not going to cut the tissue." Zheng Ren was holding the optical tweezer equipment in his hand. Wu Hang had never seen it before, and he didn't know what it was.

"Oh." Wu Hang was a little disappointed.

It turns out that Boss Zheng can't do it either.

He came to Zheng Ren and said, "Boss Zheng, come with me to see if the prepared organization is appropriate."

As he said that, Wu Hang took Zheng Ren to the material collection room.

A large room of more than 100 square meters, with all kinds of containers.

Zheng Ren knew that the body tissue removed by his surgery would be sent to the pathology department to obtain materials from this.

The chopping board on that side is the place where technicians take materials.

The tissue that is surgically cut off and waits for pathological treatment must be followed by a series of steps such as material extraction, fixation, dehydration and transparency, soaking and embedding, sectioning patches, staining and sealing, and then the slides can be left to be downloaded, and the pathological morphology of the body's lesion tissue is observed under a microscope.

The first step is to find materials. Every day, seeing those strange-shaped tissues and smelling formalin and anhydrous alcohol, Zheng Ren felt that he could not work in the pathology department.

Every department has its own difficulties.

Try to complete Mr. Li’s pathological diagnosis, so we should come here less in the future.

"Boss Zheng, how many m are you going to use a slicer?" Wu Hang asked.

"No." Zheng Ren smiled. Seeing Wu Hang put on gloves and took out the pathological tissue prepared for Zheng Ren, he handed the optical tweezers to Professor Rudolph Wagner, and then used tweezers to remove a trace of tissue.

Wu Hang was stunned. What is the use of such a silk-like pathological tissue? It has uneven thickness and cannot be dyed at all. Observe.

"Boss Zheng, you are..." Wu Hang asked tentatively.

"I want to test the optical tweezers."

“…”

Wu Hang really doesn't know what optical tweezers are. The world's cutting-edge technology has not yet entered the clinical stage. For doctors in various clinical departments, this is a fantasy.

The removed tissue was placed in a container, and Wu Hang took Zheng Ren to the director's single room.

There is a table inside with a brand new microscope above.

"Boss Zheng, it's a coincidence today. The director is resting." Wu Hang smiled and said, "This microscope is our best, for the director. It's a baby. Please be gentle. If you really have some problems, the director will cause trouble for me."

"Yeah." Zheng Ren nodded repeatedly.

It was probably because Wu Hang was unsure when he saw him coming with his equipment, so he gave him a message.

He put the pathological tissue aside, first looked at the director's microscope, and then understood the model and installed the optical tweezers on the microscope.

Wu Hang was still worried or confused at first.

Do microscopes need additional components? They should not be needed! At least I have worked for ten years and have never seen similar components appear.

So he was very afraid that Boss Zheng would destroy the director's microscope.

If this is broken, I am afraid the director will kick himself into the frozen group during the operation and squat for a year or two...

When Wu Hang thought of the intraoperative frozen in ten or eight units every day, he felt that he was in a bad mood.

Half an hour later, Zheng Ren completed the equipment installation.

"Boss, this is Gaha." The professor was confused and asked.

"Optical tweezers can be installed on a normal microscope, and then the pathological tissue is observed with a microscope, and the pathological cells are retrieved with optical tweezers." Zheng Ren explained.

"Boss, this is too troublesome," said Professor Rudolf Wagner. "We don't use it at all. Even if the pathology department is not reliable, it can be done with slices. If it really doesn't work, it's impossible to mail pathology slices to Heidelberg. Our colleagues..."
