"Mr. Cheng, let''s not waste more time. Now let''s talk about the treatment process of the operation." Wu Mian said when he saw that the projector was ready.


    "Thank you." Cheng Yunhai said after taking the medicine orally.


    "However, it should be noted in advance that this operation does not solve the fundamental problem. Some people have problems with the coagulation mechanism and often have thrombosis, while you have thrombosis because of the working principle of the third generation artificial heart."


    "You can rest assured that if it can be relieved, I will replace the artificial heart as soon as possible."


    "OK, let me explain to you the process and principle of the operation." Wu Mian nodded and said, "the operation is called lateral tibial bone transfer and microcirculation regeneration. That may be boring. Let me tell you the reason for this technology first."


    "Russian orthopedic doctor Jia A. Ilizarov has found through long-term test and clinical practice that human bones, like connective tissue and epithelial tissue in human body, have great regeneration and plasticity.


    As long as doctors master the law of its development and growth and use certain medical means, bones can grow or shorten according to the wishes of doctors to a certain extent, so as to "recover" the lost fingers and toes due to trauma. "


    Seeing that Cheng Yunhai was confused, Wu Mian further simplified the complex things.


    "The earliest application in China is to break the lower leg, and then open a certain distance to let the bone grow and increase."


    "I know!" Cheng Yunhai said.


    Matthew De also nodded gently. "I heard that there was a nurse in the third hospital. She was very short and it was difficult to change drops. The nurse finally chose this kind of heightening operation, and the postoperative recovery was good. Before, everyone was worried that the limbs on both sides were not the same length, but there was no big problem after the operation."


    Wu Mian nodded and continued.


    "Jia A. Ilizarov spent more than ten years in-depth research on technology and theory, and finally formed the tension stress law of tensile tissue regeneration.


    Among them, orthopaedic technology and distraction osteogenesis theory are praised as a new milestone in the history of orthopaedics by the international orthopaedic community. "


    The treatment pictures of relevant operations constantly flash on PTT. The patient''s legs are supported by a metal frame, two metal pipes pass through, and there are scales on one side of the metal frame, which seems to be adjustable.


    Some patients only have shelves on their lower legs. In the last few pictures, the patients'' thighs and lower legs are supported by metal shelves.


    "When I was in Massachusetts, I once performed this kind of heightening operation on two girls who wanted to be models. The postoperative effect... Is beyond words." Wu Mian said, "there are many complications. Although the increase is 6.5cm, I don''t think this operation is good."


    When Wu Mian used the word "bad", Matthew smiled.


    "It''s like sleeve gastrectomy under endoscopy. I met a girl who lost weight a few days ago and had postoperative complications. The damage to the patient is too great and there is not enough necessity, so it''s not recommended."


    "I didn''t think much at that time. Later, I met a patient similar to you and suddenly thought of the operation of Jia A. Ilizarov."


    "The essence of this operation is to use the regenerative function of the human body to achieve clinical purposes. Moreover, the reconstruction after tibial fracture... In short, the body will enter an emergency state and begin to rebuild blood vessels."


    Cheng Yunhai probably understood what Wu Mian said.


    "To have an operation, first of all, we must confirm the patency of the popliteal artery by B-ultrasound. I just had a rough physical examination and just touched the popliteal artery."


    "I have tried to perform the operation in the case of popliteal artery occlusion. The probability of revascularization in mice is only 65.6%. Fortunately, your popliteal artery condition is good and should not affect the operation results."


    "I have done 178 cases of this operation with mice, and the effect is ideal. After entering the clinic, due to time reasons, only 21 patients and 25 affected limbs have undergone this kind of operation. However, I think the existing data have clinical significance and can be spread out in the clinic." the ppt in front of Wu Mian was replaced with a series of data.


    Cheng Yunhai looked carefully. The data showed that there were 12 males and 9 females; The age ranged from 48 to 79 years, with an average of (62 ± 8) years. There were 11 cases of right lower limb, 8 cases of left lower limb and 3 cases of both lower limbs; Diagnosis of thromboangiitis obliterans 8 limbs


    Then Wu Mian stopped talking and replaced it with pictures.


    Pictures before and after the operation appeared in front of Cheng Yunhai. Wu Mian pays attention to Cheng Yunhai''s eyes. Every time he reads a picture, the next one will appear in his field of vision.


    Cheng Yunhai was in a trance when he saw those "familiar" pictures. They were so familiar. Although most of them seemed lighter than his own situation, there were a few heavier cases.


    The PPT produced by Wu Mian is "considerate", focusing on patients with very serious conditions.


    From skin temperature monitoring to vascular network reconstruction under B-ultrasound, each step has detailed records.


    Later, Cheng Yunhai noticed a recurring movement called accordion technology.


    The lateral movement of tibia was started on the 5th day after operation, and the free tibial window was moved by 1mm every day, which was completed in four times, continuous lateral movement for 21 days, and then reverse movement at the same speed for 21 days.


    Your own bones... Pull them back, drag them over again and jump horizontally again and again.


    Cheng Yunhai is a little helpless. He can''t think of this picture at all. Once he thinks about it carefully, he will feel more pain in his right lower limb. The accordion moves. The name is very appropriate.


    Nevertheless, the effect of the operation is really very good.


    After stopping moving for 4 weeks, remove the external fixation bracket of bone moving, and fix the bracket for about 10 weeks. The dressing of the small ulcer surface was changed every day, and the ulcer surface healed naturally. The large ulcer surface was repaired by skin grafting after the granulation of the wound surface was produced in 3 ~ 4 weeks.


    Although the whole process can be called long, the effect is very good.


    Wu Mian also showed a video of the patient at the end of the PPT.


    It was an old man with a white beard. He was in a wheelchair and Wu Mian stood two meters in front of him.


    There was no sound in the video. Wu Mian kept using gestures to greet the old man and let him stand up.


    Obviously, the old man was not very confident, he hesitated.


    A full minute later, he barely stood up. His legs were weak. With the help of a nurse, he tried to take a step.


    Although it was only 2 meters away, the old man was very excited. He walked slowly to Wu Mian and cried silently with Wu Mian in his arms.


    "This is how you see the heaviest patient recover." Wu Mian closed the PPT and said with a smile, "that''s the basic principle. I''m sure you''ve seen it. What''s the problem?"


    "Why didn''t Mayo and Cleveland doctors recommend this operation?" Cheng Yunhai asked.


    "Because their level is average," said Wu Mian calmly.
