Cushing incision is known as the best scalp incision design in history.


    In the field of early neurosurgery, many people question whether this kind of operation to open the skull should be done or not because of serious postoperative complications.


    Cushing, who taught at Yale University at that time, paid great attention to the strict aseptic treatment principle of the wound, which greatly reduced the incidence of serious postoperative complications.


    This allowed neurosurgery to survive and thrive in the early stage of development in the face of doubts from all parties.


    Because some complex neurosurgery operations are not only to open the skull and enter the brain, but also to face countless difficulties and obstacles. Even skin incision is very important.


    Neurosurgeons are used to designing surgical incisions in advance before surgery.


    For the scalp incision designed in advance, the following factors must be considered: scalp vascular anatomy, noninvasive tissue treatment, incision suture and reconstruction technology.


    Everything is very important, but it is very difficult to take into account these aspects.


    Ren Haitao doesn''t know much about this. He still remembers that once he was only responsible for neurosurgical anesthesia, and the invited Professor modu used the Cushing incision.


    When the incision was completed, the professor was very proud and talked a lot of relevant knowledge while doing the operation.


    From the migration of fibroblasts to the disordered collagen under the scalp, and then to the blood vessels and nerves under the scalp, such as superior orbital artery, superior trochlear artery, superficial temporal artery, posterior auricular artery and occipital artery.


    The design of surgical incision should avoid these arteries as much as possible and avoid crossing most branches of these arteries; This method can preserve as many flaps with vascular pedicle as possible.


    Because it has nothing to do with anesthesia, Ren Haitao just listens and knows that Cushing''s incision is awesome. But I didn''t expect that under the delicate and weak Chu Zhixi''s knife, a smooth Cushing incision appeared directly without hesitation.


    It''s like drawing the path with methylene blue early in the morning, but it''s invisible methylene blue, which Ren Haitao can''t see.


    How long did Professor modu use it before? It seems that it took at least 5 minutes to open the skin with the help of an assistant. Looking at his expression, I should be quite satisfied with the speed.


    And how long did chuzhixi use it? 10 seconds? 20 seconds?


    Ren Haitao is in a trance. No wonder people say that Professor Chu has done a good job in meningioma in petroclival area. The average survival time of malignant tumor after operation is more than 3 years. It turns out that the level of others is really high.


    A person, a knife, a hemostatic forceps and a cook usually complete the Cushing incision.


    This needs to be familiar with local anatomy!


    Ren Haitao was stunned, and the surgical incision with a longitudinal length of about 10cm and a transverse length of about 7cm has been completed.


    Facing the red blood, Chu Zhixi is no longer the weak girl and turns into the legendary spice girl without warning.


    Before hot mom and hot girls became popular, there was a saying of hot girls in the operating room. It refers to those female surgeons engaged in non obstetrics and Gynecology, especially the chief surgeon.


    Bold and delicate, delicate body bears the same pressure as male doctors. People in the operating room are called hot girls.


    I didn''t expect Professor Chu Zhixi Chu... Also, he is a professor. How can he not be a hot girl. Ren Haitao immediately changed his concept and straightened out his "wrong" cognition of Chu Zhixi.


    In less than 2 minutes, Chu Zhixi stopped bleeding.


    A piece of gauze stained with blood was handed over to the instrument nurse. Chu Zhixi didn''t lift his head. He continued to cut the skin, subcutaneous tissue and nuchal ligament from the midline. Under the periosteum, the attached muscles and soft tissues on the spinous process and vertebral lamina were stripped outward, and the dry gauze was used to block and compress hemostasis.


    Then she exposed the occipital tubercle and cervical 2 and 3 spinous processes to the largest position of the second spinous process as the positioning mark of the operation.


    The technique is as simple and clean as teacher Wu. Ren Haitao has judgment in his heart.


    It doesn''t seem difficult, but it''s impossible to do this step without more than ten or twenty years of training.


    At least none of the neurosurgery professors and directors of the second hospital of Medical University is so sharp.


    Then Chu Zhixi''s action slowed down, no longer unrestrained, but entered the meticulous rhythm of neurosurgery.


    The operation was clean. Ren Haitao saw it clearly. Chu Zhixi was dissociating the atlas nodule. About 1.5cm from the middle line of atlas arch belongs to the restricted area of operation. That side is the vertebral artery. Once it is damaged, the consequences will be unimaginable.


    The surgical incision is huge, nearly 20cm, unrestrained. It can be really subtle. Chu Zhixi has free tissue in the operation area of about 2cm and has spare power.


    This operation is really a long experience. Ren Haitao sighed in his heart.


    From time to time, he took a look at the values of ventilator, monitor and micropump, took care of his work first, and then watched the top surgeons perform surgery.


    He scanned again. When his eyes returned to the operation area, there was suddenly another person.


    Wu Mian, teacher Wu, did not know when to stand opposite Chu Zhixi and began to assist her in dissociation.


    "Miss Wu... Have you finished?" Ren Haitao asked in surprise.


    "Hmm? What do you mean?" Wu Mian didn''t look up and touched the hemostatic forceps to assist Chu Zhixi''s operation. He asked faintly on his mouth.


    Ren Haitao looked up at the iliac operation area. The suture has been completed. A newly taken iliac bone graft is placed in the sterile area of the instrument nurse, fresh with blood


    I''m so stupid. How could I ask such a standard question! Ren Haitao then became nervous and couldn''t make such a stupid mistake again. Otherwise, what would Mr. Wu do without himself in the future.


    "Drill bit." Wu Mian whispered, and then Chu Zhixi stretched out his left hand.


    After a full 10 seconds, the special safety fine drill and related drilling equipment were handed over to Chu Zhixi.


    Because it is not a fixed instrument nurse, and even the instrument nurse is not familiar with this complex operation, the cooperation is a little rusty.


    If you change your grumpy Professor, you will start swearing, Ren Haitao thought to himself. But no matter Wu Mian or Chu Zhixi, they all look quiet. They seem to have been familiar with this rhythm for a long time.


    Teacher Wu is really a strange performer. Ren Haitao sighed.


    Under the operating table, he is gentle and friendly most of the time, but occasionally he is grumpy... Others are grumpy towards people at the Dean level.


    For example, the one from the county hospital and the one who has just been raised in the hospital. Although the hospital is not comparable, how can we say that both of them are presidents.


    But once on the operating table, Mr. Wu was as quiet as a virgin.


    "Buzzing ~ ~"


    Buzzing fame interrupted Ren Haitao''s thoughts, and a special safety fine drill bit began to drill.


    Nearby is the brain stem. Accidentally, the drill bit "snapped" for 0.5cm, and the patient was lifeless immediately.


    “3.2mm。”


    After opening, Wu Mian communicated with Chu Zhixi for the first time.
