"Praise to you, boss!" Professor Rudolf Wagner said: "It is now a common view in Europe that it will take at least 20 years for optical tweezers to enter clinical practice. And you, the great one, are ready to start using them now?"
"Try it, I don't know if it will work." Zheng Ren said modestly.
After spending almost all of the surgical training time in the system space last night, Zheng Ren had already mastered the use of optical tweezers.
The professor followed Zheng Ren obediently to the pathology department.
Although he is an interventional doctor, he has considerable knowledge of cutting-edge technologies.
Even if it is not a surgical method and is only used for diagnosis, the professor is still curious and wants to see how Zheng Ren operates it.
When I arrived at the pathology department, I was greeted by the faint smell of formalin mixed with the smell of absolute alcohol.
The taste was very bland, Zheng Ren still frowned.
It seems that I am not suitable to work in the pathology department. The taste of this noodle is too great. Especially anhydrous alcohol, you will get drunk if you smell it too much.
At that time, let the patient’s family members complain about working under the influence of alcohol...
Zheng Ren was thinking wildly and looking at the people in the pathology department, he felt a little worried.
Su Yun only gave himself a name. There were more than a dozen mosaics in front of him that were constantly moving. Which one was it
"Wu Hang, is Mr. Wu here?" Zheng Ren asked.
"Boss Zheng." A man was looking at a film under a microscope. When he heard Zheng Ren speak, he raised his head.
He is not tall, but has a big head, like a big-headed son in a cartoon, which looks a little uncoordinated.
"Mr. Wu, hello, I'm Zheng Ren." Zheng Ren said politely.
"Brother Yun told me that you want to debug the machine?" Wu Hang stood up, handed over the work at hand to the assistant next to him, and came to Zheng Ren's side.
"Well, I want to give it a try, and I would like to ask you to give me a piece of tissue."
"I'm ready for you. Today's hepatobiliary surgery is considering hepatocellular carcinoma. Are you going to use a machine to cut it or do it manually? At your level, are you going to cut micron-level slices directly by hand?" Wu Hang He asked expectantly.
The microtome in the pathology department has a scale, usually 0-50μm, which can be adjusted according to different specimens.
Wu Hang had heard of Zheng Ren. Several major events in 912 recently were related to Zheng Ren. It was difficult not to know about him.
Su Yun didn't say anything in detail, he just said that Boss Zheng was going to do a pathological biopsy. Wu Hang thought Zheng Ren was going to cut it himself with a knife, so he was particularly curious.
If a surgical operation is performed well, can it really replace the machine and make a few μm-thin slices on its own
That's amazing!
Wu Hang's big head was dangling in front of him, which made Zheng Ren feel uncomfortable for a while.
"Mr. Wu, what are you looking for?" Zheng Ren asked.
"Knife!" Wu Hang was a little excited. Every male doctor has a heart to become the best surgeon.
"Well… "
"I heard that the surgical instruments you use are specially made. A blade costs 233 US dollars? Why don't you bring it with you? Can ordinary blades achieve micron-level accuracy?" Wu Hang couldn't wait.
"That's true, but I'm not going to cut the tissue." Zheng Ren was holding optical tweezers equipment in his hand. Wu Hang had never seen it before, so 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 and see if the prepared organization is suitable."
With that said, Wu Hang took Zheng Ren to the material collection room.
A large room of more than 100 square meters is filled with various containers.
Zheng Ren knew that the roving nurses in the operating room would send the body tissues removed from his surgery to the pathology department, where the materials would be collected.
The cutting board on the other side is where the craftsmen draw materials.
Tissues cut out by surgery and waiting for pathology must go through a series of steps such as sampling, fixation, dehydration and transparency, wax embedding, sectioning and patching, staining and sealing, etc. before the slides can be left to observe the pathological morphology of the diseased tissue in the body under a microscope. .
Obtaining materials is the first step. Seeing those strange-shaped tissues every day and smelling the smell of formalin and absolute alcohol, Zheng Ren felt that it was impossible for him to work in the pathology department.
Every department has its own difficulties.
Try to complete Mr. Li's pathological diagnosis, and you should come here less often in the future.
"Boss Zheng, how many micrometers do you want for the microtome?" Wu Hang asked.
"No need." Zheng Ren smiled. Seeing Wu Hang put on gloves and took out the pathological tissue prepared for Zheng Ren, he handed the optical tweezers equipment to Professor Rudolf Wagner, and then used the tweezers to remove a trace of tissue.
Wu Hang was stunned. What was the use of such a thread-like pathological tissue? The thickness is uneven and cannot be dyed or observed at all.
"Boss Zheng, what are you..." Wu Hang asked tentatively.
"I want to experiment with optical tweezers."
“…”
Wu Hang really doesn't know what optical tweezers are. The world's cutting-edge technology has not yet entered clinical practice. 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 private room.
There is a table inside with a brand new microscope on it.
"Boss Zheng, it's a coincidence that today, the director has a rest." Wu Hang said with a smile: "This microscope is our best one, and it is only for the director. It's precious, please be gentle. If something goes wrong, director It’s time to trouble me.”
"Yeah." Zheng Ren nodded repeatedly.
Wu Hang probably felt unsure when he saw him coming with the equipment, so he gave the instruction.
He put the pathological tissue aside and looked at the director's microscope first. After understanding the model, he installed the optical tweezers equipment on the microscope.
Wu Hang was a little worried and didn't understand at first.
Does the microscope need additional components? Probably not necessary! At least in the ten years I have been working, I have never seen similar components appear.
So he was afraid that Boss Zheng would damage the director's microscope.
If this thing breaks down, I'm afraid the director will kick me to the intraoperative freezing unit and have to squat for a year or two...
When he thought about the eight or ten surgeries being performed every day, Wu Hang felt that his whole body was not well.
Half an hour later, Zheng Ren completed the equipment installation.
"Boss, is this Gaha?" the professor looked confused and asked.
"The optical tweezers device can be installed on an ordinary microscope, and then the pathological tissue can be observed with the microscope, and the pathological cells can be removed using the optical tweezers device," 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, it can still do slices and other things. If it is really impossible to mail the pathological slices to Heidelberg, we colleague… "
"Fugui'er, that's not the case." Zheng Ren smiled, "This is a trial first. If it is possible, we will conduct a biopsy under the CT room image to collect pathological specimens. That is the time to actually use optical tweezers."
