Because of the establishment of left heart circulation, the repair of aorta is much smaller!


    Even so, it can''t cover up Chen Cang''s technology when repairing the aorta!


    This involves a "tire repair" technology.


    The difference may be that this fetus is a living fetus!


    How to skillfully combine the artificial vascular patch with its own aortic patch is a skill.


    Tao Mi looked at Chen Cang''s selection of propylene line 4 and couldn''t help sighing.


    It''s true that skilled people are bold. Fine suture can indeed increase the tightness of vascular wall suture and make the vascular wall of aorta more firm, but it has higher requirements for suture speed.


    However, when Chen Cang was sewing, he suddenly had a thought, and then... Frowned a little!


    He found that the speed and tightness of vascular wall suture were not the only choice.


    When suturing, how to make the intima and adventitia fit better, and then increase the effective function of the vascular wall is very important!


    There are also many requirements for the tension of vascular wall, the damage force of vascular intima, the recovery ability of the whole vascular wall and so on!


    Chen Cang inevitably fell into deeper thinking!


    How to choose the best suture of large blood vessels!


    What problems should we pay attention to when repairing heart and large blood vessels


    ……


    Thinking of this, Chen Cang sighed.


    it''s too hard.


    However, this is certainly not an easy thing. The repair and suture of blood vessels have been studied for so many years, just like tendon suture.


    Naturally, this will not happen overnight.


    Take your time to study it!


    Thinking of this, Chen Cang breathed a sigh of relief and continued to start his work.


    Tao MI and Zhang Wenfu, on the other side, were stunned when they saw Chen Cang like this. This sigh... Some people were filled with emotion!


    This kind of sigh has a faint sadness, mixed with emotion and helplessness about their own technology


    This is clearly dissatisfied with their own technology!


    Disappointed eyes with a trace of regret and unwilling, slightly wrinkled forehead full of sighs.


    This makes the eyes of the "master and servant" outside their hearts jump.


    Isn''t that satisfactory?


    How high do you have to ask for yourself!


    Zhang Wenfu looked at the young man with some emotion and some shame. Suddenly, he reflected on whether he had been too lazy these years?


    Why are people so excellent!


    Aren''t you satisfied with yourself?


    There is no end to learning!


    And I''m dissatisfied with this bottle, half bottle shaking level... It seems that I''ve been fooling around.


    The more Zhang Wenfu thought, the more ashamed he was.


    After going back this evening, my wife will call herself again. She should hold back, shut herself in the study and read for an hour!


    But Tao MI was quite pleased.


    To put it bluntly, at his age, because of physical strength, many skills are more than heart but less than strength. Even with Chen Cang''s insight, he can''t operate like Chen Cang.


    Because surgery, after all, depends on talent and physical strength.


    This talent includes physical skills and talents!


    These things can''t be made up by hard work.


    For example, this tight and fast suture is not only achieved by efforts, but also includes many things.


    An operation, all three sighed!


    Qin Xiaoyuan was very upset when he saw it.


    Just sew it. Why are you sighing?


    ……


    After Chen Cang could not repair the aorta, he began to deal with the esophagus.


    It''s just, do you need bud patch or not?


    The fistula of esophagus is not big or small, which can be used or does not need to be used.


    This needs to be measured by the attending physician!


    Xiao he found Chen Cang''s hesitation.


    If the opening is too large, the mattress suture can be successful, but the scar tissue and the recovery process will undoubtedly affect the function of the esophagus and cause esophageal stenosis.


    But if you use a patch, there will be side effects!


    In this way, Chen Cang obviously fell into a dilemma.


    At this time, how to measure and optimize is very important.


    Chen Cang''s eyes misguided thinking and judgment, how to take the next operation.


    His eyes began to see more clearly the surrounding necrotic tissue.


    Chen Cang began to get rid of the rotten and necrotic esophagus!


    However, he was very cautious in the resection of dissection, because... He still did not plan to use patch and simply suture the esophagus.


    Xiao He and Tao Mi looked at each other with some doubt.


    Will this work?


    Because at this time, if the suture is far fetched, it''s better to rest assured as a patch.


    Chen Cang''s eyes can clearly see and divide the necrotic tissue. Chen Cang doesn''t cut as much as possible, but can keep it directly.


    Soon, the organization was completely cleared!


    At this time, Chen Cang took the lead in stretching and suturing the innermost mucosal layer of the esophagus.


    At this time, the position of the fistula is just between the first stricture and the second stricture of the esophagus. Chen Cang''s ingenious mucosal stretching allows the esophagus to anastomose at this time!


    This operation immediately brightened everyone''s eyes!


    Xiao he couldn''t help clapping his hands!


    A weak angle can just straighten the narrow without affecting the physiological channel. In this way, it has undoubtedly become the best choice!


    Such a choice is really a genius!


    Because of such an angle stretching, how did you think of it?


    Now Xiao He wants to ask Chen Cang if he is having surgery with a protractor and a triangular plate!


    Or do you have a ruler in your eyes?


    There''s no such operation!


    Tao MI is also a bright spot. Good boy, it''s really powerful!


    Chen Cang didn''t relax, because the suture of mucosal layer is only a part, and then there is the suture of inner muscle layer and outer membrane. This angle must be well controlled!


    The whole operation has undoubtedly changed from a simple fistula repair operation to a precise optimized suture of esophagus.


    This makes Xiao He, who has been engaged in esophageal work for a long time, can''t help clapping his hands and praising!


    Although Qin Xiaoyuan didn''t know about the operation, he was surprised to see that Chen Cang repaired a hole so well.


    Chen Cang''s next work was simple and continued to finish the operation.


    Chen Cang didn''t ask others to help too much, because... The system said that the higher the participation, the richer the reward!


    In this operation, the patch is useless when repairing his esophagus. It all depends on his hand


    This participation should be very high!


    Thinking of this, Chen Cang suddenly looked forward to it. Can he give him a perfect?


    Count gauze... Sort out equipment


    The operation is almost finished!


    Head nurse Li Ying looked at Chen Cang with a smile in her eyes.


    To tell the truth, he likes Chen Cang very much. After all, this boy... Saves gauze!


    you ''re right.


    Chen Cang''s operation should be the most economical.


    Less bleeding and no redundant operation, which greatly improves the accuracy of the operation.
