Chapter 1393 Are You Going to Cut It Yourself?

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

"Try it, I don't know if it will work or not." Zheng Ren said "humbly".

He spent almost all the surgical training time in the system space last night, 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 considerable knowledge of cutting-edge technologies.

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 came to the pathology department, the faint smell of formalin mixed with the smell of anhydrous alcohol rushed towards me.

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

It seems that I am not suitable to work in the pathology department, this side tastes too much. Especially anhydrous alcohol, if you smell too much, you will get drunk.

At that time, let the patient's family complain to work after drinking...

Zheng Ren was thinking wildly, looking at the pathology department, feeling a little worried.

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

"May I ask if Mr. Wu Hang is here?" Zheng Ren asked.

"Boss Zheng." A man was looking at the film under the microscope, listening to Zheng Ren's words and raising his head.

He is not tall, but has a big head, like a big-headed son in a cartoon, looking 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 to the assistant next to him, and came to Zheng Ren.

"Well, if I want to try it out, I would like to trouble you to give me a piece of tissue."

"It's ready for you. Today's hepatobiliary surgery is considered to be hepatocellular carcinoma. Are you going to cut it with a machine or manually? At your level, are you going to cut micron-level sections directly by hand?" Wu Hang asked expectantly.

There is a scale on the microtome of the pathology department, generally 0-50μm, which can be adjusted according to different specimens.

Wu Hang had heard of Zheng Ren. Several major events in the recent 9/12 event were related to Zheng Ren. It would be difficult to know if he was not.

Su Yun didn't say anything carefully, but just said that Boss Zheng was coming to do a pathological biopsy. Wu Hang thought that Zheng Ren would use a knife to cut it himself, so he was very curious.

If the surgery is done well, can it really replace the machine to make a few μm thin slices by itself?

That's amazing!

Wu Hang's big head swayed in front of him, and Zheng Ren felt 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 the heart to become the best surgeon.

"Uh……"

"I heard that the surgical instruments you use are specially made. A blade is $233? Why didn't you bring it? Can ordinary blades achieve micron-level precision?" Wu Hang couldn't wait.

"That's right, but I'm not going to cut the tissue." Zheng Ren held the optical tweezers device 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 to see if the prepared organization is suitable."

Having said that, Wu Hang brought Zheng Ren to the collection room.

A large room of more than 100 square meters is filled with various containers.

Zheng Ren knew that the body tissues removed by his own surgery would be sent to the pathology department by the roving nurses in the operating room, and the materials would be collected here.

The chopping board on the other side is the place where the craftsmen draw materials.

The tissue that is cut out by surgery and waiting for pathology needs to go through a series of steps such as material sampling, fixation, dehydration and transparency, wax embedding, slice patch, dyeing and sealing. .

Collecting materials is the first step. Seeing those strange-shaped tissues every day and smelling formalin and anhydrous alcohol, Zheng Ren felt that it was impossible for him to work in the pathology department.

Every department has its difficulties.

Try to complete the pathological diagnosis of Li Lao, in the future, I will still come here less.

"Boss Zheng, how many microns do you want to use with a microtome?" Wu Hang asked.

"No." Zheng Ren smiled. Seeing that 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 tweezers to remove a trace of tissue.

Wu Hang was stunned, what is the use of such a silk-like pathological tissue? The thickness is uneven, and it is impossible to dye and observe at all.

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

"I'm going to experiment with optical tweezers."

"..."

Wu Hang really didn't know what optical tweezers were. The world's cutting-edge technology has not yet entered the clinic. 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.

Inside was a table with a brand new microscope on it.

"Boss Zheng, it's just a coincidence today, the director is taking a rest." Wu Hang said with a smile: "This microscope is our best one. It's for the director's use. It's baby, please take it easy. If something goes wrong, director It's time to trouble me."

"Hmm." Zheng Ren nodded again and again.

It is estimated that Wu Hang saw that he came here with the equipment, and he was not sure, so he ordered a sentence.

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

At first, Wu Hang still had some small worries and incomprehension.

Do I need additional components for the microscope? Should not be needed! At least I have been working for ten years, and I have never seen similar components appear.

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

If this special thing is broken, I am afraid that the director will kick himself into the freezing group during the operation and go to squat for a year or two...

When he thought of the intraoperative freezing of ten and eight units every day, Wu Hang felt that his whole body was not well.

After half an hour, Zheng Ren completed the equipment installation.

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

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

"Boss, this is too much trouble." Professor Rudolf Wagner said: "We don't use it at all. No matter how unreliable the pathology department is, we can do slices and so on. It's really impossible to mail the pathology slices to Heidelberg. colleague……"

"Fugui'er, that's not the case." Zheng Ren smiled. "This is a first try. If possible, a biopsy is required to obtain a pathological specimen under the CT image. That's when the optical tweezers are really used."
