"Doctor Li is about to start his lecture, you start recording." Director Duan said.

The cameraman checked the tape again, turned on the camera, and faced Li Zheng.

"Begin." said the cameraman.

Li Zheng picked up a pen and pointed at the overall framework on the drawing. He said, "Our limb tissues can actually be extended. The prerequisite is that there must be continuous tension. Whether it's bones, muscles, nerves, blood vessels, or skin, under the action of continuous tension, they can grow synchronously at a slow pace every day..."

"This...Brother Zheng, how did you know?" Zhang Yong couldn't help but ask.

"Don't talk. If you have any questions, wait until I finish speaking," Director Duan said sternly. Videotapes are very expensive.

Zhang Yong shut up immediately.

The other doctors also gave up the idea of ​​asking.

Li Zheng continued, "Using this characteristic, we can use this external fixator to stretch the limb of patients with bone defects and nonunions by 1 mm per day. This way, over time, we can achieve the desired length."

"This external fixator has a three-dimensional design. It can precisely adjust the force line and rotation angle of the lower limbs. It also allows for partial weight bearing early on to stimulate new bone formation..."

Li Zheng explained the principles and characteristics in one breath.

Everyone just felt like they had discovered a new world.

"This is a completely new concept and treatment system!" Director Duan exclaimed.

He did not doubt the feasibility of this method because Li Zheng explained it so systematically, covering everything from principles to precautions, as well as advantages and disadvantages.

This must have been something he came up with after solid theoretical deduction.

Even though it has not been clinically verified, Director Duan has no doubt about the feasibility of this method.

After all, he is an orthopedic surgeon himself, so he can still judge whether it is possible to achieve.

After listening to this, Zhu Qidong was completely convinced.

Even when I was taking advanced studies in the province, I had never heard of this technology. It wasn't even available in the entire country.

"Brother Zheng, what's wrong with your brain? You can even come up with such a magical idea!" Zhu Qidong exclaimed.

"Yeah, I'm completely stunned! According to this concept, can't it be used to increase height?"

Everyone has this idea.

After breaking the tibia, the bone is lengthened.

Without further ado, if you grow 5 centimeters taller, your aura will be completely different.

Especially for those who are too short, it can definitely change their destiny.

Li Zheng shook his head and said, "This method is theoretically sound for increasing height, but the cost is quite high and the risks are also significant. Currently, it's limited to clinical treatment."

In later generations, some people did use this technology to increase their height, but the long treatment cycle, infection, postoperative nonunion, malunion, etc., brought more pain to those who wanted to increase their height.

Therefore, there is a lot of controversy about whether it can be used to increase height, and most doctors do not dare to use it lightly.

Everyone nodded.

There hasn't been any clinical treatment yet, but you're already thinking about all sorts of things.

Once the technology is more mature and its use is proficient, we can consider non-therapeutic applications.

After explaining the principle, Li Zheng handed the blueprint to Duan Jianhui and said, "Director Duan, please find an equipment company to customize a set. If that's not possible and the cost is too high, I can go to a blacksmith shop to make it. Except for the Kirschner wire, the others are external parts. You can just bring them back and disinfect them yourself."

Director Duan nodded and said, "I'll contact them first. The Kirschner wires are readily available, but the three rings are a bit special, and the connecting rod also needs to be threaded. It shouldn't be difficult for the medical device company. It just depends on whether they are willing to make the mold."

Li Zheng nodded and said, "Ask them to reply as soon as possible. This type of shelf will be widely used in the future, and the demand will be high."

After the discussion, Li Zheng said again: "Director Duan, after the first-stage reimplantation of both lower legs of this patient survives, the second-stage external fixation replacement surgery can be performed here, but the post-operative limb lengthening treatment will require returning to the county, and I will personally adjust the external fixation frame."

"no problem!"

Director Duan did not hesitate at all and just wanted the surgery to be done here. As for follow-up treatment, Li Zheng wanted to keep the patient here and did not dare to take it himself.

"Now, thank you all for your hard work in the post-operative treatment. I will come back to see you in a few days." Li Zheng said, and it was time to leave.

"Don't worry, Qidong is here, nothing will happen."

Li Zheng nodded, called Chen Dayong and Lin Xiaomei, and left the orthopedics department.

Director Duan took Li Zheng and others to the parking lot in front of the inpatient department.

Before Li Zheng got into the car, Director Duan handed him another envelope.

"Director, this patient is not necessary. I originally borrowed your hospital to perform surgery." Li Zheng refused.

"Hey, take it. This is not just a flying knife. This is a teaching operation. We can't even learn such a high-end operation even if we spend money!" Director Duan said, forcing the envelope to Li Zheng.

In this parking lot, Li Zheng didn't want to refuse and accepted the envelope.

After getting on the ambulance, the group rushed to the county.

"Dayong, I have something to do tonight, so please pay more attention in the department." Li Zheng said, sitting in the middle seat of the front row.

"Oh? What's the matter, brother?" Chen Dayong was curious. Brother Zheng didn't have many acquaintances in the county.

Li Zheng smiled faintly and said, "I'm going to Xiaomei's house tonight. My father-in-law and mother-in-law want to meet me."

Hearing this, Lin Xiaomei, who was sitting next to Li Zheng, blushed suddenly.

We haven't even decided to get the marriage certificate yet, why did you call me?

However, a sense of happiness arose in my heart.

Brother Zheng is really sure about his relationship with me!

"Haha, brother, sure!" Chen Dayong laughed loudly, "Hurry up and get the wedding done. I haven't had a wedding banquet in a long time!"

Lin Xiaomei quickly turned her head to the side, looked out the window, and unconsciously rubbed her braids with her hands.

"Don't be anxious. The parents of both parties haven't met yet. Let them decide the marriage. We should focus our main energy on our careers." Li Zheng shook his head.

"That's fine, anyway, I'm so happy!"

Chen Dayong was really happy for Li Zheng. After ups and downs in the past two years, things were finally back on track.

In order not to delay things, Chen Dayong used his driving skills to the fullest.

Soon returned to the county hospital.

After getting off the car, Chen Dayong suggested using his own Changjiang 750 to take Li Zheng and the others there.

Li Zheng didn't refuse either.

Although Lin Xiaomei's home is in the county town, it is not very convenient to take the bus there.

"Let's go to the mall and buy some gifts first," Li Zheng suggested.

Lin Xiaomei shook her head and said, "Just buy some fruit. They won't be happy with gifts!"

Li Zheng still felt that a little fruit was inappropriate.

Lin Xiaomei looked at Li Zheng and said with a smile: "Don't buy it, you are the best gift!"

All right.

Li Zheng no longer insisted.

Chen Dayong just felt that he was redundant, so he quickly sent the two people over and finished the job.
