Since 1981 Health School Chapter 769

Chapter 769 Titanium alloy material appears

 The idea of ​​​​surgery is often that if your patient lacks something, you should find a way to autologously transplant it from other parts of the body.

For example, when Chen Qi had a nose plastic surgery before, because he was missing a nasal bone, a part of the ear cartilage or costal cartilage was cut to replace it.

 An example is skin grafting for burns. If the skin here is burned away, a part of the skin from other parts of the body is transplanted to replace it.

 But now there is a question. The patient is missing a piece of facial skull. What should I do?

Maxilla, this bone is located in the middle of the face. There is one bone on the left and right, which are connected to each other to form the support of the midface.

The maxillary body has bony processes that connect the body to four adjacent bones. For example, the frontal process is connected to the frontal bone, the zygomatic process is connected to the zygomatic bone, the palatine process is connected to the left and right sides of the midline of the palate, and the alveolar process is the bone where the teeth are located. quality.

If the maxillary bone is defective due to tumors, it will directly affect the appearance of the face. The sunken deformity in the middle of the face will be very ugly.

 Because the eyeball, nasal cavity, and infraorbital area of ​​the maxilla have lost their bony support, many functions will be affected.

 For example, eye movement is limited and double vision occurs;

 Collapse of the nasal cavity, dryness or discharge of pus in the nasal cavity;

Since the oral cavity is directly connected to the nasal cavity and maxillary sinus, it is difficult to speak clearly, and food will enter the nasal cavity when eating;

 Some maxillary defects can also affect mouth opening and other functions due to inflammation.

 So maxillary defects not only seriously affect social functions in appearance, but also have a great impact on all aspects, including language, swallowing, eating, mouth opening, and breathing.

 If Xiao Wenxiang's bones were in a “convex” shape before the surgery, then they might become a “concave” shape after the surgery. So what's the point of the surgery?

Professor Ge is still very worried:

“Chen Qi, what should we do now? The maxillary bone is gone, we can't just suture it, right?”

 Chen Qi is a little strange:

"Lao Ge, although maxillary loss is a big problem, it is not incurable. What do you have to worry about? Do you think that maxillary loss cannot be repaired?"

 Chen Qi has realized that his perception of his past and present lives may have been biased, and he may not have been able to repair his maxillary bone in 1990.

 Sure enough, Professor Ge said angrily:

“How do you repair the maxillary bone? Even if I break off some bones and fill the hole, how can I fix it? This is not a handicraft. The damaged areas can be fixed with glue.”

Chen Qi thought to himself that it was indeed the case, no wonder the old man was so anxious to get angry.

“Although bones cannot be glued together, we can use spacers to assist in fixing them just like carpenters.”

Ge Minghua rolled his eyes at Chen Qi:

“Gasket, your idea is good, but I have never heard of the principle of gaskets. Besides, even if you can use gaskets, how do you choose the bones? Which part of the bones should be used to fill the hole?”

Chen Qi chuckled: "Okay, okay, I know the true level of your Peking University professor. Since you let me be the chief surgeon, of course I have thought about this kind of thing."

Chen Qi looked at the head nurse again at this time:

“Head nurse, please help me bring that box over, yes, that box, and then you can open it.”

The head nurse didn't know why, but the rule in the operating room was that the chief surgeon was the biggest, so she obeyed and took out a silver-white metal piece from the lock box.

Professor Ge blinked and had a guess in his mind: "Chen Qi, this is..."

“Yes, this is the metal gasket I prepared. This thing is very precious. We don't have to buy it in China.”

 “What material is this?”

 “Titanium alloy.”

“Titanium alloy?” Professor Ge and everyone were shocked again.

Titanium alloys were not news a few decades later, but in 1990, titanium alloys represented the latest materials technology of this era.

In this era, titanium alloys are mainly used for military purposes, such as making aircraft engine compressor parts, followed by structural parts for rockets, missiles and high-speed aircraft.

 Furthermore, titanium alloys are extremely expensive in this era, and almost all of them need to be imported.

Our country's research on corrosion-resistant titanium alloys and high-strength titanium alloys is still quite lagging behind. Of course, we accelerated our efforts and narrowed the gap.

 Decades later, it was the era when Chen Qi worked in his previous life.

Titanium alloys have been widely used in the medical field because of their high strength, low density, non-toxicity, good biocompatibility and corrosion resistance.

 It is the first choice material for medical products such as artificial joints, bone trauma, spinal orthopedic internal fixation systems, dental implants, artificial heart valves, interventional cardiovascular stents, surgical instruments, etc.

 The shocked Professor Ge hurriedly asked: "Chen Qi, where did you get these titanium materials?"

Chen Qi thought to himself, should I tell you that these are all taken from the material warehouse of my space operating room?

"Well, I originally bought these titanium materials from the United States. They were purely paid for by myself and used for experimental surgeries. I didn't take them out because I felt sorry for the little patients. Otherwise, you three students at Peking University would use this money. Will the hospital reimburse me?"

“Bah, the patient still owes us a lot of surgery fees. How can we, Peking University Third Hospital, replenish it for you? But this titanium is such a treasure. Do you have more? Give me some?”

This time it was Chen Qi's turn to roll his eyes: "What are you thinking about? It's such a small piece, thousands of dollars."

 In fact, Professor Ge is a little cautious. Peking University is a top university. What kind of laboratory does it not have? If we can get a piece of titanium alloy material and study it at that time, it may be able to promote the development of medical titanium alloys.

 It's done, it's a big gold mine. At this time, everyone in the multimedia classroom saw the head nurse holding several silver-gray metal plates, and they were also confused.

"What is this?"

“It feels like a metal object. I guess it's for bone loss repair, right?”

 Because it can be seen in the camera at this time that the surgeon is comparing the "leak", which is obviously for repair.

“For repair purposes, ordinary metal materials can't be used, right? This will cause rejection.”

“No, no, could it be made of titanium alloy? We also have this in the orthopedics department, but the shape is different.”

“Oh~~~This Peking University Hospital is really rich and wealthy. It's even made of titanium alloy.”

Meng Yushu also said to the people next to him at this time:

“This Lao Ge is not afraid of bankruptcy. If a piece of titanium alloy is really worth tens of thousands of yuan, he may not be able to buy it if he still has the money. He is really willing to do so.”

“It seems that Comrade Lao Ge not only has a high medical level, but also has a very high ideological level. He is worthy of our study.”

 Meng Yushu rolled his eyes at the doctor sitting next to him and continued to look at the TV screen.

At this time, the doctor can be seen on the TV screen disinfecting the patient's buttocks.

Several young doctors were surprised: "No, this is not a facial and skull surgery. How come the buttocks are disinfected? Isn't this irrelevant?"

 A professor from Jishuitan Hospital chuckled:

"Don't you know this? Professor Ge is obviously planning to use the patient's own iliac bone to fill the hole in the missing maxillary bone. It can be seen that Professor Ge's clinical level is closely in line with international mainstream technology. awesome."

 “Oh~~~That's it.”

“Professor Ge turns out to be so powerful. He is indeed a professor at Peking University and a candidate for election as a member of the academic department.”

“No wonder he dares to take patients that others dare not take. It seems that this year's by-election is none other than Professor Ge.”

Everyone is talking about it. Without comparison, there is no harm. Professor Ge has continuously used several new surgical techniques and completed difficult surgical steps one after another, which is eye-opening to onlookers.

 In comparison, professors such as Meng Yushu and Fang Bing appear dim.

　　After all, people are performing on stage, and they can only sit in the audience and be the audience. There is a difference in level, and the judgment is based on who is superior.

 At this time, Chen Qi had quickly cut open the skin in front of the ilium and started to remove the bones.

The terrible thing is that the bone of the iliac bone is also very hard, so Chen Qi had to use the electric saw again, and he did not dare to cut more.

The removed iliac bone was fixed on a titanium alloy plate. Chen Qi fixed the bone with a titanium plate on the young patient's skull and fixed it with screws. The rest is to let the osteoblasts and osteoclasts in the periosteum Take your time to integrate.

Finally, Chen Qi took out the mandible and installed it on the joint like a machine part. The entire bone surgical procedure was completed.

 After doing all this, Chen Qi motioned the camera to zoom in and took a close-up of the repaired facial skull.

 The entire wound surface is clean and refreshing.

At this point, experienced old professors all saw that the operation was successful.

Just like building a house, the load-bearing walls and columns have been built, and then only some decoration work is left. This is the simplest work.

 Chen Qi's next step was to put the two eyeballs back into the eye frames, and also used a mesh bag of a new type of material to fix them.

 The excess tissue on the face is then removed, and then the entire face is sutured back together.

 Of course, for laymen, this face cannot be seen at all, because the facial features have not yet been fully reflected, but for expert doctors, the operation is over.

 When Chen Qi finished the last stitch, he nodded to Professor Ge.

Professor Ge was so excited that he really wanted to hug Chen Qi and give him a kiss.

 But now during the live broadcast, Professor Ge suppressed his excitement and pretended to be calm and said:

"Okay colleagues, today's fibrous dysplasia surgery is over. Thank you all for watching. Please criticize and correct any shortcomings. If you need a video of the surgery, you can contact the Science and Education Department of Peking University Third Hospital. Contact us, this live broadcast ends here.”

  turned off the live broadcast camera, and just as Professor Ge was about to cheer, he found that Chen Qi was no longer in the operating room.

 “Hey, Chen, where is Chen Qi?”

 Chen Qi ran to the toilet as quickly as possible, and then drained the water.

“Damn it, if you hold in your urine all day long, you will get prostate disease sooner or later.”
