Sisi's X-ray, CT, MRI, PET-CT are all open on a large electronic reading screen.

In order to obtain the function of the lower limb as soon as possible, a custom-made titanium alloy prosthesis was used to bridge the femur to make up for the loss of 20 centimeters, and the two ends of the prosthesis were inserted into the medullary cavity and fixed with bone cement.

This is a palliative practice that aims only to allow her to obtain a functional lower limb in a limited time, to be able to walk, and to facilitate care. Her osteosarcoma had metastasized to multiple parts of the body, and other methods, such as fibular grafting, allogeneic bone grafting, or Ilizarov bone lengthening techniques, were not suitable, and the recovery time was too long for a patient with advanced tumors.

"Can a full femoral implant be replaced?" With 3D printing technology? ”

Song Zimo proposed that the orthopedic laboratory 3D printer can already be applied, and this machine is industrial-grade, equivalent to a 3D printer bed.

Yang Ping shook his head: "As an organ, the femur is not simply replaced, it has a lot of muscles attached to it, and there are joint capsules and ligaments attached at both ends, these tendon soft tissues rely on the mechanism of tendon bone healing for firm attachment, joint capsule and ligament maintain the static stability of the hip and knee joints, and the muscles not only maintain the dynamic stability of the joints, but also provide the power of movement." To carry out total femoral replacement, the problem of soft tissue attachment needs to be solved, otherwise this femur can only play a supporting role, there is no motor function, and even the supporting role can only play a little bit. The soft tissues and bones of the human body can be healed, and artificial materials can not be healed, if this problem is solved, it is estimated that it is a breakthrough in orthopedic technology, we can not use this method at present, but we can do a subject to study it. ”

"Amputation?"

Xiao Wu's opinion, since it cannot be replaced, can only be intercepted.

This is a feasible plan to remove the tumor and the infringed femur, but after the resection, only a little bit of the femur remains, and the right lower limb will lose its function due to the loss of the femur, and then use a customized prosthesis, which can no longer be effectively controlled.

"It has spread all over the body, amputation is of little significance, and it is much better to keep the limb, at least psychologically."

Zhang Lin also expressed his opinion, everyone was very positive, and if they were wrong, Yang Ping would not criticize them.

"What about your opinion? Brother? Song Zimo watched Yang Ping flip through the film, and never said his opinion.

"The original prosthesis that bridged the femur was removed, the tumor was cut off along with the invaded femur, and the bone was lengthened using the Ilizarov technique, giving her a normal femur." Yang Ping thought for a long time and said.

Song Zimo thinks that this method is too idealistic and unrealistic: "She is in the advanced stage of osteosarcoma, do you plan to cure it radically with this treatment?" Impossible. ”

The cruel subtext, Song Zimo didn't say: her survival period may be shorter than this extended duration. The progress of one millimeter per day, even if it is twenty centimeters, needs to last for more than two hundred days, can she hold on for so long?

"I know it's impossible to cure the roots, but I want to work in the best direction and go as far as I can." Yang Ping is very resolute, he wants to fight for it, and the quixotic style is also fine.

Everyone was silent, and Yang Ping continued to flip through the film alone: "I know that she is in this situation, and she should give up medically, but I want to work hard and work towards the best goal, even if it is a step forward!" ”

Song Zimo's hand was on his shoulder: "I don't agree with your point of view, but I support you." ”

"I support it too!" Zhang Lin Xiaowu also cast encouraging glances.

"Using the infrared navigation equipment in the operating room, we will do a three-dimensional reconstruction of the tumor infrared scan for her, use indocyanine green for imaging, and then integrate the three-dimensional reconstruction images of CT and MRI to obtain a complete tumor image, which will be imported into the host of the surgical navigation system, and we will use infrared navigation to do the operation at that time." Yang Ping removed the hand holding the mouse.

"These reconstructions are done by the respective machine software and cannot be combined into a single image." Xiao Wu is more familiar with medical equipment.

Yang Ping told Xiao Wu: "We design a software by ourselves to do comprehensive reconstruction, Xiao Wu, don't you have a specialty in this area, you can find a few students from Nandu Institute of Technology to work together." ”

"It's a big project!" Xiao Wu used to be in school and helped the tutor do these things.

"It's not big, it's not called a subject, and it's difficult to go to the moon, but it's still realized, Song Zimo, you take them to set up this project, you don't need to apply for other topics, just apply for the hospital's overseas Chinese fund, so fast." Yang Ping gives everyone confidence.

Hearing Yang Ping's decision, everyone was also very encouraged, and they were all eager to try, senior brother, this is going to make some big moves, some scientific research achievements, write high-quality papers, and everyone will evaluate the title in the future.

The soul of a team is very important, he must be in the right direction and determined, just like a flag erected, everyone can gather under the banner and move forward towards the goal unremittingly, Yang Ping has done this.

"Saturday, my birthday, hold a birthday party at home in the evening, I must come over when I have time, they are all in our circle, Shao Wei and Lao Zhou will come, by the way, I will introduce you to some friends."

Just after discussing Sisi's condition, Su Nanchen did not send WeChat, but called to invite. As a friend, you must go to participate, but you can't go empty-handed, you have to bring some gifts.

Yang Ping is embarrassed, he is really not good at gift-giving. He called Song Zimo, Xiao Wu, and Zhang Lin over again to discuss the matter together.

Everyone, you say a word, I a sentence, and I haven't come to any good conclusions, none of these big men have come up with good ideas, they send high-end pens, surgical goggles, the latest English orthopedic monographs, all ideas.

Let's go to Xiao Su, the girl should know more, Yang Ping went to Xiao Su again and discussed with her: "What kind of gift do you say I give, it's impossible to seal a red envelope, it's so cheesy." ”

Xiao Su has a lot of ideas, thought about it and said: "I have an idea, you are all surgery fans, you will reconstruct the knee and shoulder ligament surgery, let Xiao Wu and a few of them help you make an animation demonstration, the key steps and surgical mysteries are explained thoroughly, combined with the video of your usual surgery, burned into a set of CDs, as a gift to him, he must be very happy, obsessed with surgery, there is nothing more important than gaining valuable surgical experience, I will help you find someone to get the outer packaging box, will definitely make your friend satisfied." ”

"Great! This is a good idea, it seems that my brain is easy to use when I do surgery, I really don't know anything about these things in life, Xiao Su's idea is good, this gift is ingenious, and it is very valuable, so it is decided. Yang Ping decided immediately.

Then I found Song Zimo, Xiaowu, Zhang Lin and three people, and asked them to help make animations and burn CDs. Song Zimo has done so many surgeries with himself, and he is well versed in the mystery of this kind of surgery, Xiao Wu will make animations, and Zhang Lin is responsible for text commentary, and this matter is finalized.

"A meal, pick the place! Must be completed by Friday night. Yang Ping made a condition.

"Pick what? It's true. Xiao Wu smiled evilly.

Yang Ping hesitated: "It's all brothers, look up and don't look down, start a little lighter." ”

"It's only a few days, I'm afraid it's too late, isn't it?" Song Zimo shook his head, looking very embarrassed.

"Yes, the time is so tight, just make a PPT, the animation is too time-consuming."

"Text explanations don't take a few days to come up with."

Yang Ping looked at these guys, colluded, and shook their heads, "It's difficult, it's difficult!" ".

"Okay, you can pick the location at will, start with the weight, brother doesn't care." Yang Ping understands these few.

"Well, although the time is tight, but everyone works overtime, it shouldn't be a big problem." Song Zimo immediately changed his words.

Zhang Lin Xiaowu also echoed: "It's all brothers, let's work overtime, and ensure delivery before Friday night." ”

A bunch of foodies! Yang Ping advised: "Call the fat man too." ”

Zhang Lin was anxious: "What are you calling him for, are you really out of the way?" He can't help with anything, how many do you eat at a time? Double your bill! ”

"If you go out, call him to help pick a place and order food, none of you are as professional as him." Yang Ping explained.

Everyone doesn't refute it, this is the truth, in terms of eating, it has risen to a professional level, and the fat brother is really killing everyone in seconds, after all, he was the former president of the Food Association.

"Bring your girlfriend along!" Su Nanchen sent a WeChat.

What should I do about this matter, take Xiao Su there? I was going to look for Xiao Su again, Yang Ping went upstairs, rang the doorbell in the operating room, and Xiao Su came out.

The door of the operation opened, Yang Ping didn't go in, stood at the door, and showed her Su Nanchen's WeChat: "He asked me to bring my girlfriend with me?" How do I reply to him? Do you have time to go along? Yang Ping's face was a little red.

Xiao Su laughed eatingly, and then looked very embarrassed: "I'm sorry, I'm going home on Saturday night, it just so happens that I have a family and a birthday, so I can't accompany you." ”

"What a coincidence!" Yang Ping was a little disappointed.

"Or? I'll talk to my family and accompany you? Xiao Su lowered his head and pursed his mouth.

"That's not good, I'll just go alone, you must accompany your family, I don't have to be with you, it's okay, I'll just explain it to him." Yang Ping said.

"There is no need to explain, the more you explain, the more you can't explain."

The mobile phone was in Xiao Su's hand, Xiao Su held the mobile phone, and his fingers flicked: "Hmph!" I'll help you reply and tell him directly, you haven't talked about a girlfriend yet, see what he means, it won't be a temptation to test you, I want to introduce you to a girlfriend, right? ”

"No, you're angry?" Yang Ping heard Xiao Su snort lowly.

Xiao Su pouted: "I won't be angry, someone is so active in helping you introduce your girlfriend, I'm happy, haha, it means that I have a good vision, maybe he has a sister or something, I want to introduce it to you, you have a relationship with the surname Su." ”

"Don't think about it, people just mention it casually." Yang Ping said.

"If he introduces you to a girlfriend, you won't be tempted, will you?" Xiao Su's long eyelashes flickered.

Yang Ping shook his head: "I want to be tempted, but I can't." ”

"You--"

"Because my heart has been filled with a man."

Xiao Su turned into a smile, stretched out a finger, and gently tapped it on Yang Ping's forehead: "It's about the same." ”
