  The middle bend is used to do things like a retractor at this time. Pulling and prying open this incision exposes a wide and small field of vision for the doctor to operate as much as possible. Adults are inconvenient to operate here, and children are young and have small bones. This limitation is even more severe.

  Student Pan Shihua's eyes were wide open. He, who had only seen abdominal surgery before, experienced non-abdominal surgery for the first time, and could indeed feel that he was undergoing an upgraded version of the surgery.

  Different from him, Xie had experienced pediatric surgery and read cardiothoracic surgery. He was much calmer, and directly stretched out his hand to the chief surgeon and said, "Dr. Duan, I'll help you open it up."

   Duan Sanbao glanced at her with his round eyes, and gave her the middle curve.

   Classmate Pan can read the look of the chief knife and the suspicion that Classmate Xie wrote is: Do you have the strength?

  It turns out that when Duan Sanbao assisted Xie with intubation, he took the initiative to get the vascular forceps to open the incision because he was afraid that Xie would have no strength. Retractors need strength. This kind of hooks are made of curved pliers incisions. Don't think that they are small and useless. Wrong, the small incision here does not mean that the surrounding human tissue is missing, the surrounding human tissue is the same as it is pulled apart, to be precise, it is more laborious than the hook. At least the hook is good to hold the whole hand or even rely on the whole body to exert force. If the middle bend is not good, only the finger force is required.

  Student Duan Sanbao's suspicions are well-founded, but Duan Sanbao doesn't know that Xie is a girl in their class who can wrestle with boys. Classmate Pan suddenly had a ghost idea in his heart, quietly watching other people overturn like the boys in their class.

   took Xie, who was taking the middle bend, and inserted the bend into the upper edge of the sternum quickly and accurately. The others were instantly surprised by her lightning-fast movements.

  Everyone was surprised at the ruthlessness she showed as a girl, so it was like super ruthless. Actually no, they didn't push in hard at all, they weren't tough people, they were gentle people, they really saw the place and stuck close to the gap between flesh and blood. The insertion is accurate, there is no obstacle, and it is definitely faster than hard insertion.

   When a group of people realized this, they all opened their mouths in astonishment: This?

  Student Duan Sanbao's round eyes were round and round, and a sense of ominousness suddenly rose in his heart.

   Sure enough, Xie had no difficulty when he used the middle bend to open the surgical field for him.

  The pressure rolled back from the first aid to the main knife.

  Student Duan Sanbao understands why the teachers prefer to play light music instead of passionate music, because the master knife needs a sense of mental balance too. Sometimes a good assistant is unknowingly urging the chief knife.

   Sister Nurse looked at it again, she didn't need to let go of her courage, so she quickly played a soothing piano song.

  The sound of the music has changed, and everyone's mentality has been adjusted. There is no need for passion to emerge at this moment, what is needed is to be cautious and cautious. There are too many large blood vessels around here.

  The main surgeon picked up the electric knife, cut the periosteum on the sternum in the exposed surgical field, and cleaned the nearby ligaments.

   The first assistant and the second assistant, who have not been paired with the main sword, suddenly heard the main sword in the innermost part of the story as if he was talking about something.

   "There's a transverse jugular vein here, and there's an innominate vein at the back of the left side, and there are more small venous masses here—"
