With blunt separation, the esophagus was separated from the cardiac position and exposed to the operation field.


    On the outer wall of the esophagus, traces of blue and black can be vaguely seen. Fortunately, the esophagus has not been corroded thoroughly. It is estimated that there should be no major problem after the operation.


    "Mr. Wu, there''s no problem stitching after cutting." director Liu was still worried and asked in a low voice.


    The problem of esophagus is blood supply. Whether it is esophageal cancer or esophageal diverticulum, surgery has to face the same thing. If the postoperative blood supply is not good and the incision is not long, we have to face the problem of esophageal fistula.


    "It''s all right." Wu Mian said softly and continued the operation.


    Director Liu felt that if he changed his position in the operator, he should be able to separate, remove the foreign body and sew it. The operation is not difficult. The key is manipulation. Here is the most key point of the whole operation.


    "Sharp knife."


    Wu Mian stretched out his hand. Five seconds later, the instrument nurse put the sharp knife on the handle and patted it in Wu Mian''s hand.


    The speed was slightly slow, and Wu Mian was helpless. After all, I''m not an instrument nurse who always cooperates with me. I can''t reach out and clap the appropriate instrument in the palm of my hand.


    The sharp knife fell.


    "Miss Wu!" director Liu shouted subconsciously, "it''s not there!"


    The position of Wu Mian''s knife drop is about 1cm worse than that of director Liu''s blue and black. This is a very serious surgical mistake! The position is too far off the mark.


    "Prepare a small intestinal pressure plate, the smallest one." Wu Mian ignored director Liu''s objection, but said to the instrument nurse.


    Small intestinal pressure plate? In a flash, director Liu understood what Wu Mian meant.


    They are all chief doctors. They have had thousands of esophageal operations. Although they are a little confused for a moment, they want to understand what''s going on.


    Mr. Wu is worried that the battery will fall off and cause secondary chemical burns in the child''s esophagus.


    But is that all right? Director Liu has some doubts.


    After changing several intestinal pressure plates, Wu Mian was not very satisfied. He knew that the equipment of medical sophomore was not complete enough. After all, similar operations are quite rare, and it is normal to have no instruments.


    "Director Liu, please," said Wu Mian.


    "Ah?"


    "Block it with small curved pliers, keep your hands steady, and keep the jaw open at a distance of 0.62cm."


    “……”


    Director Liu understood what Wu Mian said. However, the small bending pliers should keep the opening distance of 0.62cm. How can you do it yourself?


    The pliers went in along the incision. After Wu Mian adjusted the position, he handed the pliers handle to Director Liu.


    "Keep this angle and mouth opening for 5 minutes and 10 seconds," Wu Mian said.


    Director Liu was speechless. He carefully took the small curved pliers and tried to keep the distance when Wu Mian was handed over to him.


    The smallest pliers are basically not used when he has an operation. When he saw Mr. Wu Mian doing an operation, he couldn''t see the difficulty at all. Step by step, just doing it step by step.


    But when the pliers fell on the hand, as before, the cotton did not exert force. It''s fine, but it''s really difficult for director Liu to control the smallest hemostatic forceps.


    Even if it is not free, but just to block the button, the battery will not fall off, which is quite difficult.


    At the same time, Wu Mian and Chu Zhixi began to blunt separation with a hemostatic forceps. The sharp knife occasionally fell and cut and dissociated in the invisible gap.


    This is not the traditional local anatomy, but the local anatomy in microsurgery.


    Director Liu has good eyesight, but it is difficult to see the specific operation of the two small hemostatic forceps.


    Wu Mian and Chu Zhixi had a tacit understanding. No one spoke. They knew what to do next. Lift, pull, pull and leave, clean and neat.


    After 2 ′ 12 ″, local capillaries were dissociated.


    Director Liu''s blood is boiling. Can surgery still do this? Peripheral capillaries are usually cut off directly, because it is no less difficult to separate them.


    But Mr. Wu did so, still under his nose!


    This operation is the peak level, director Liu thought.


    Although there are few capillary networks, they can be preserved, and the blood supply of postoperative esophageal incision can be guaranteed. The possibility of esophageal fistula is very small.


    But how did Miss Wu do it?


    Just thinking, director Liu heard Wu Mian''s voice, "director Liu, please put your thumb out for another two cents."


    “……”


    MB, is this human work? 2 millimetres is 2 millimeters. I can''t even draw a millimeter distance with my fingers. Now I have an operation. You make me... Director Liu almost didn''t cry.


    "Don''t move." Wu Mian then said. His right hand gently rested on the back of director Liu''s hand. The tip of his thumb touched the inner side of director Liu''s thumb and exerted slight force.


    "Move with my strength, don''t resist," said Wu Mian.


    Director Liu calmed down and felt the power from Wu Mian''s fingers. If you are not careful, you can''t notice the movement of Wu Mian''s fingers, but even director Liu''s careful feeling is still difficult to detect.


    "Well, that''s it. Hold on."


    Wu Mian finished and continued to operate with Chu Zhixi.


    Did you move your finger just now? It seems to move, or it seems not to move at all. Director Liu dared not move and recalled the moment just now.


    Her eyes looked at three hemostatic forceps and a small forceps moving constantly in the narrow operation area, but she didn''t walk her mind at all.


    The whole heart was thinking about the movement of just 2 millimetres. When she woke up, she happened to see the hemostatic pliers clamp a blackened button battery out.


    What did Mr. Wu and Professor Chu do just now? Director Liu really wants to cry this time.


    Mr. Wu''s operation was not slow at the beginning. Every step was very clear. It didn''t look like anything. But when we get to the key place, how can we speed up?


    How did you do it! Director Liu shouted in her heart, but she dared not ask and was embarrassed to ask.


    The previous words are still ringing in my ears. Director Liu''s heart is broken.


    It''s not something that ordinary people can do. This sentence is like a whip, or the one dipped in cold water and pumped on the face.


    "Director Liu, you can jog a little." Wu Mian said gently, "it''s hard."


    "..." director Liu doesn''t even know what he has done. He doesn''t know where the hard work is.


    Continue to free, carefully cut off the necrotic tissue, suture and rebuild the capillaries.


    Wu Mian''s operation resumed its original speed.


    "Miss Wu, how do I feel that the operation is slow again?" director Liu asked in a trance.


    "No, it''s always done at a constant speed. It''s not the Olympic Games, so don''t grab so much time." Wu Mian said. "Maybe you''re not familiar with naked eye microsurgery, so you think the free part can be done faster. It''s all right. If you have the opportunity to practice. Even if you can''t do it, you''ll understand."
