Chapter 1394

"Praise you, boss!" Professor Rudolf Wagner said: "it is now a common view in Europe that optical tweezers will enter the clinic for at least 20 years. And the great you are ready to use now?"

"Try it. I don't know if I can do it." Zheng Ren said modestly.

After nearly all the operation training time in the system space last night, Zheng Ren has preliminarily mastered the use of optical tweezers.

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

Although he is a doctor in interventional science, 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 also very curious and wants to see how Zheng Ren operates.

When he came to the pathology department, a faint smell of formalin mixed with the smell of anhydrous alcohol rushed towards him.

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

It seems that he is not suitable to work in the pathology department. This side tastes too much. Especially anhydrous alcohol. You'll get drunk if you smell too much.

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

Zheng Ren is cranky. Looking at the people in the pathology department, he is a little worried.

Su Yun only gave himself a name. In front of him, more than a dozen mosaics are constantly moving. Which is it?

"Excuse me, is Mr. Wu Hangwu there?" Zheng Ren asked.

"Boss Zheng." A man was watching a film under a microscope, listening to Zheng Ren and raising his head.

He is not tall, but his head is big, like the big son in the cartoon. He looks a little uncoordinated.

"Mr. Wu, Hello, this is 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 his assistant, and came to Zheng Ren.

"Well, if you want to try, please give me an organization."

"Here you are. Today's hepatobiliary surgery will consider hepatocellular carcinoma. Are you going to cut it by machine or manually? At your level, are you going to cut micron slices directly by hand?" Wu Hang asked eagerly.

There is a scale on the slicer in the pathology department, which is generally 0-50 μ m. It can be adjusted according to different specimens.

Wu Hang has heard of Zheng Ren. Recently 912 several major events have something to do with Zheng Ren. It's hard to know him.

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

The surgery is well done. It can really replace the machine to make a few by itself μ M thin slices?

That's amazing!

Wu Hang's big head swayed in front of him, and Zheng Ren felt uncomfortable.

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

"Knife!" Wu Hang is a little excited. Every male doctor has a heart to become the best surgeon.

"Er..."

"It's said that the surgical instrument you use is specially made. A blade costs $233? Why don't you bring it? Can an ordinary blade achieve micron accuracy?" Wu Hang can't wait.

"That's right, but I don't want to be prepared." Zheng Ren has optical tweezers in his hand. Wu Hang has never seen it. He doesn't know what it is.

"Oh." Wu Hang was a little disappointed.

It turns out that boss Zheng can't do it.

He came to Zheng Ren and said, "boss Zheng, come with me to see if the organization is suitable."

With that, Wu Hang took Zheng Ren to the material room.

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

Zheng Ren knows that the body tissue removed by his own operation and the itinerant nurses in the operating room will be sent to the pathology department to take materials here.

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

For the tissue cut off by surgery and waiting for pathology, a series of steps should be taken, such as material extraction, fixation, dehydration and transparency, wax embedding, slicing and pasting, dyeing and sealing, so as to save and download the slide and observe the pathological morphology of the diseased tissue under the microscope.

Taking materials is the first step. Seeing those strange tissues and smelling formalin and anhydrous alcohol every day, Zheng Ren felt that he could not work in the pathology department.

Every department has its own difficulties.

Try to complete the pathological diagnosis of old Li. We should come here less in the future.

"Boss Zheng, how much do you want with the slicer μ M's? " Wu Hang asked.

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

Wu Hang was stunned. What's the use of such a silk like pathological tissue? Uneven thickness makes it impossible to dye and observe.

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

"I'll try optical tweezers."

“……”

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

The removed tissue was put in a container. Wu Hang took Zheng Ren to the director's room.

There is a table in it. On it is a brand-new microscope.

"Boss Zheng, it's a coincidence today. The director has a rest." Wu Hang said with a smile, "this microscope is the best one we have. It's for the director only. Baby, please keep it light. If something goes wrong, the director should trouble me."

"Uh huh." Zheng Ren nodded again and again.

It was estimated that Wu Hang had no idea when he saw himself coming with equipment, so he gave an order.

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

Wu Hang began to have some small worries and incomprehension.

Do you need any additional components for the microscope? It should not be necessary! At least I haven't seen similar components for ten years.

So he was afraid that boss Zheng would break the director's microscope.

If it breaks down, I'm afraid the director will kick himself into the intraoperative freezing group and squat for a year or two

At the thought of freezing ten or eight sets every day, Wu Hang felt that the whole person was not good.

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

"Boss, this is GAHA." The professor looked confused and asked.

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

"Boss, it's too troublesome." Professor Rudolph Wagner said: "we don't have to come at all. Even if the pathology department is no longer reliable, we can do slicing. It's really not good. We can mail the pathological slicing to Heidelberg. Our colleagues..."

"Rich son, not so." Zheng Ren smiled. "This is to try first. If you can, you should take pathological specimens by puncture biopsy under the CT room image. That's the time to really use optical tweezers."
