What a courageous person, not to mention that there are not many female medical students and male medical students like her. Dean Wu's eyes flashed and he asked her: "First tell me how you want other people to cooperate with you."
"Teacher Wu" is awesome, and every question he asks is to the point.
"When I pull out the knife, I must squeeze the knife in the opposite direction and expand the lower opening so that Teacher Wu's fingers can be easily inserted and operated. The blade should be tilted to where there is space to avoid injuring other parts."
Xie Wanying analyzed the situation at the scene in a clear and logical manner, looking directly at the knife edge as if a CT machine was shining into the multi-slice scan. "When the knife comes out, it is not as strong as when it was inserted, and it has to pass through the perinephric fascia and extraperitoneal area again."
There are many layers of structures such as fat layer, muscle layer, peritoneum, transversus abdominis, internal oblique muscle, and external oblique muscle. At this time, after the knife is inserted, these tissues should wrap around the knife surface and contract. Therefore, the retractor looks like
What Teacher Wu said is very important."
"You need them to help you pull it out before you can get the knife out smoothly, right?"
"Yes, the better they pull, the smaller the resistance, and the easier it is for the knife to come out without injuring other tissues again."
After the junior sister's analysis, the pressure fell entirely on the shoulders of the two senior brothers. The fact is that the junior sister is not shirking responsibility, but it is really the case.
"Doctor Yin, how are you? After hearing this, are you still not confident?" Dean Wu turned to ask Yin Fengchun again.
Yin Fengchun nodded this time and changed his tune: "I have confidence in everyone."
The reason why he was not confident before was because a group of people spoke in too general terms. How could he not be frightened about how to extract the tissue? There was no way to do it. Surgery was most afraid of chaos and disorder. The human body cannot be left to the surgeon.
Some patients who died on the operating table died because the surgeon was out of his mind and was not even sure where to stop the bleeding. How could the patient survive?
"Okay, everyone, please take your positions." Dean Wu said.
Yin Fengchun walked to the opposite side,
Song Xuelin handed over the handle of the knife to Xie Wanying. His new task was to get the suction tube and help Yin Fengchun suck blood and lymph fluid to clean the surgical field if necessary.
Dean Wu's hands were in a ready position.
Yin Fengchun's two fingers tightly clasped the two openings of the atrial appendage forceps.
The anesthetists all stood at the head of the bed, watching as this most tense moment was about to begin.
Dean Wu narrowed his eyes and gave a steady order: "Start."
It was the one who pulled the hook first, rather than randomly pulling it out.
The retractors on both sides were pulled toward the outer edge, and it was clearly visible in the incision that all layers of tissue were turned outwards and exposed, and blood squeaked out. The surgeons wearing surgical magnifying glasses opened their eyes to the maximum limit, and did not even dare to blink their eyelids and stared hard.
Surgery center.
Yin Fengchun's mind felt like it was going to collapse again. Seeing the splitting of every layer of tissue in her body on the blade was equivalent to reliving the process of the knife piercing her body.
Whether it was an accident or not, in his surgeon's eyes this was clearly murder.
"Doctor Yin." Cao Yong, standing next to him, whispered, reminding him to forget other things.
Now is the critical moment to save her. Yin Fengchun narrowed his eyes. Like everyone else, his pupils narrowed and his mind cleared everything else, leaving only the layers of human tissue. He returned to the original surgical anatomy class.
Only when you understand clearly what is what and what is it, you can know how to operate it next.
