"Praise you, boss!" Professor Rudolf Wagner said. "The general view in Europe now is that optical tweezers will be used in clinical practice for at least 20 years. And the great you, are you ready to start using it now? "
"I'll give it a try. I don't know if it will work," Zheng Ren said 'modestly'.
Last night, Zheng Ren had used almost all the surgical training time in the System space. He had already mastered the use of optical tweezers.
The professor obediently followed behind Zheng Ren and went to the pathology department.
Although he was a doctor in the field of interventional medicine, he had a considerable understanding of cutting-edge technology.
Even if it was not a surgical method and was only used for diagnosis, the professor was very curious and wanted to see how Zheng Ren operated.
When they arrived at the pathology department, a faint smell of formalin mixed with the smell of anhydrous alcohol greeted them.
The smell was very faint, but Zheng Ren still frowned.
It seemed that he was not suitable to work in the pathology department. The smell was too strong. Especially anhydrous alcohol. If he smelled it too much, he would probably get drunk.
When the time came, the patient's family would complain that he was working after drinking …
Zheng Ren's thoughts ran wild. He looked at the people in the pathology department and was a little worried.
Su Yun only gave himself one name. The dozen or so mosaics in front of him were constantly moving. Which one was it?
"May I ask if Chief Wu Hang is here?" Zheng Ren asked.
"Chief Zheng." A person was looking at the radiographic films under a microscope. When he heard Zheng Ren speak, he raised his head.
He was not tall, but his head was very big. He looked like the big-headed son in the cartoon. He looked a little out of place.
"Chief Wu, hello. I'm Zheng Ren," Zheng Ren said politely.
"Brother Yun told me that you want to come and debug the machine?" Wu Hang stood up and handed the work at hand to the assistant next to him before coming to Zheng Ren's side.
"Yes, I want to give it a try. I'll have to trouble you to give me a piece of tissue."
"It's ready for you. Today's surgery in the Department of Hepatobiliary and Pancreatic Surgery is considering hepatocellular carcinoma. Are you going to use a machine to cut it or do it manually? With your level, are you going to use your hands to cut micron slices directly? "Wu Hang asked with anticipation.
There was a scale on the microtome in the pathology department. It was usually 0-50μm and could be adjusted according to different specimens.
Wu Hang had heard of Zheng Ren. Recently, several major events in 912 were related to Zheng Ren. It was difficult not to know him.
Su Yun did not explain in detail. He only said that Boss Zheng was coming to do a pathological section. Wu Hang thought that Zheng Ren was going to cut it himself, so he was very curious.
Could a good surgeon really replace a machine to make a few μm thin slices on its own?
That was too magical!
Wu Hang's big head swayed in front of him, making Zheng Ren feel uncomfortable.
"Chief Wu, what are you looking for?"
"Scalpel!" Wu Hang was a little excited. Every male doctor had the heart to become the best surgeon.
"Uh …"
"I heard that the surgical instruments you use are specially made. One blade costs 233 USD? Why didn't you bring it? Can an ordinary blade also reach the micron level of precision? "Wu Hang couldn't wait any longer.
"That's true, but I'm not going to cut the tissue." Zheng Ren held the optical tweezers in his hand. Wu Hang had never seen it before, so he did not know what it was.
"Oh." Wu Hang was a little disappointed.
It turned out that even Boss Zheng could not do it.
He came to Zheng Ren's side and said, "Boss Zheng, come with me. Let's see if the prepared organization is suitable."
As he spoke, Wu Hang brought him to the material collection room.
It was a large room of more than a hundred square meters, filled with all kinds of containers.
Zheng Ren knew that the circulating nurses in the operating theater would send the tissues removed from the surgery to the pathology department to collect materials from there.
The chopping board was the place where the craftsmen got their materials.
The tissues that had been cut for pathology had to go through a series of steps such as material collection, fixation, dehydration, embedding, sectioning, staining, and sealing. Only then could the slides be left and the pathological morphology of the diseased tissue be observed under a microscope.
Material collection was the first step. Zheng Ren felt that he could not work in the pathology department every day when he saw the strange tissues and smelled the smell of formalin and anhydrous alcohol.
Every department had its own difficulties.
He would try to complete Old Li's pathology diagnosis and come here less in the future.
"Boss Zheng, how many μm do you want for the microtome?" Wu Hang asked.
"No need." Zheng Ren smiled. When he saw Wu Hang put on a glove and take out the pathological tissue prepared for Zheng Ren, he handed the optical tweezers to Professor Rudolf Wagner and used a pair of tweezers to remove a trace of tissue.
Wu Hang was stunned. What was the use of such a thin piece of pathological tissue? The thickness was uneven and could not be dyed or observed.
"Boss Zheng, what are you …?" Wu Hang asked tentatively.
"I want to test the optical tweezers."
"…"
Wu Hang really did not know what optical tweezers were. The world's cutting-edge technology had yet to enter the clinic. For the doctors in the clinical departments, it was a fantasy.
The tissue was placed in a container and Wu Hang brought Zheng Ren to the department chief's room.
There was a table with a brand-new microscope on it.
"Boss Zheng, what a coincidence. The chief is resting today." Wu Hang smiled. "This is our best microscope. It's specially used by the chief. It's a treasure, so please be careful. If anything goes wrong, the chief will come after me. "
"Okay." Zheng Ren nodded.
Perhaps Wu Hang saw that he had brought equipment over and was unsure of himself, so he gave him this reminder.
He put the pathological tissue aside and looked at the chief's microscope first. After understanding the model, he installed the optical tweezers on the microscope.
At first, Wu Hang was a little worried and confused.
Was there a need for an add-on for a microscope? Probably not! At least in his ten years of work, he had never seen such an add-on.
Therefore, he was afraid that Boss Zheng would break the chief's microscope.
If it broke, the department director would probably kick him to the intraoperative freezing group and make him stay there for a year or two …
Wu Hang felt sick at the thought of doing eight or ten intraoperative freezing every day.
Half an hour later, Zheng Ren finished installing the equipment.
"Boss, this is Ga Ha," the professor asked in confusion.
"The optical tweezers can be installed on an ordinary microscope. Then, we can use the microscope to observe the pathological tissue and the optical tweezers to extract the pathological cells," Zheng Ren explained.
"Boss, this is too troublesome," Professor Rudolf Wagner said. "We don't need to come at all. No matter how unreliable the pathology department is, we can still do the biopsy. If it doesn't work, we can mail the biopsy to Heidelberg. Our colleagues …"
"Lil Fugui, it's not like that." Zheng Ren smiled. "This is just a test. If it works, we have to do a biopsy under the CT room image. That's when we really use the optical tweezers."
