Chapter 1933 【1933】Retraction
Surprised by the abnormal appearance of the chief surgeon, the nurse hesitated and hurriedly delivered the prepared scalpel from the instrument table to the chief surgeon.
Crack, put the handle of the knife into the palm of the chief knife.
Chang Jiawei's eyes behind the magnifying glass narrowed slightly, his eyes fixed on the location of the surgical incision, and the sharp knife in his hand slowly cut open the skin. Longitudinal incision is made when the incision is positioned at the side of the vertebral body. The length of the incision should reach about two vertebral bodies.
The senior who was not talking seemed to have turned into a surgical machine like other teachers, and it was absolutely accurate with a single cut. Xie Wanying observed the main surgeon's movements, and at the same time assisted the main surgeon with Dr. Liu to support the main surgeon at any time.
Like other surgical operations, after the chief surgeon incisions the skin, the first assistant immediately presses the incision with gauze to stop the bleeding.
At this time, the chief surgeon replaced the electric knife in his hand, successively cut the subcutaneous tissue and electrocautered to stop the bleeding.
The very familiar creaking sound and the creaking sound of opening the breakpoint sounded again in the operating room.
The doctors were all focused on dissection layer by layer.
The lower layer of the subcutaneous tissue is the back muscles of the human body, where there are trapezius, latissimus dorsi, and rhomboid muscles. Several layers of muscle groups are cut sequentially in an orderly manner. After the muscle is cut, the retractor is brought up to expose the surgical field of view.
There is no three assists, and the second assist is on top. Xie Wanying took the retractor with both hands, and carefully put it into the left and right sides of the incision to stretch the muscles.
Today's surgery is different from the abdominal surgery she has been familiar with many times before. The abdomen is like a big sack with a deep area to enclose many things. The surgery on the back does not have such a deep and wide space. After the retractor goes down, you can really feel a tighter force, which will soon reach the bone area.
Once the operation started, everyone was busy with work, and no one would care that she was a girl. That's right, even Senior Chang, who claimed to be sympathetic to girls, didn't care if she felt bad.
Explain that as long as you are a boss, no matter how good you are on weekdays, they will only become the same when you are on the operating table: you are not polite.
The teachers only pay attention to the surgical area in front of them. If they find that she is not stretching properly, they will immediately reprimand and correct her without mercy.
Not long after the operation went on, everyone noticed that Xie was not scolded as usual.
The corners of Zhang Tinghai's lowered mouth hooked up: That's right, classmate Xie. Classmate Xie is back, same old, so it will never be boring in Classmate Xie's operating room.
Dr. Liu groaned twice in his heart, and then glanced at her out of the corner of his eye: Unexpectedly, this classmate Xie is not only fluent in academic lectures, but also has great strength in performing operations, and there is no sweat on his forehead. He was right, it was really suitable for their orthopedics department.
The strength is enough, but it must be admitted that the back muscles are not easy to pull, there is not much slack for the hands to rest, and the fatigue of the person pulling the hook increases rapidly in seconds.
Chang Jiawei, who became silent, finally spoke again and said, "Persevere."
Don't think that Senior Chang is taking special care of her, a girl. She didn't even look up and forgot who was pulling the hook here. It's just a simple good person who sees his subordinates getting tired.
When the operation has been carried out to a certain extent, the chief surgeon has confirmed that the surgical field in front of him has reached a sufficient area. Chang Jiawei gave another command: "Change the fixed retractor."
When these words fell to the ground, Dr. Liu asked the nurse to fix the retractor. The retractor is the academic name of the retractor. Ordinary retractors are tired of being pulled continuously by hand. It is better to fix the retractors by themselves and not to be pulled by others. Such a retractor is called a fixed retractor.
