Xie Wanying was a little surprised. This was her first time to observe a laparoscopic surgery up close, and the teacher should have known that she was an absolute novice in this area.
In any case, follow the teacher's arrangements.
I washed my hands before the operation and returned to the operating room, ready to stand next to the teachers and observe.
Just like traditional surgery, disinfection and draping are performed. The difference is that laparoscopy requires pneumoperitoneum to be established first. A small incision is made on the navel and a puncture device is inserted and rotated to inject an appropriate amount of CO2 gas into the abdominal cavity. When the gas is injected to a certain amount, the pneumoperitoneum machine is connected to maintain the pressure, and the cone is pulled out to replace the laparoscope. At the same time, the patient's abdominal cavity will be displayed on the monitor screen.
Then, cannulas are inserted into the lower part of the left and right mid-abdomen and above the pubic symphysis. These cannulas are used to insert surgical instruments such as ultrasonic scalpels. Laparoscopic surgery usually involves three doctors. In addition to the surgeon and the assistant, there is also a special surgeon who holds the scope.
As the name suggests, the assistant holds the laparoscope to help the surgeon see the surgical field. The surgeon usually uses an ultrasonic scalpel, and the assistant holds other instruments, such as curved forceps and aspirators, to assist the surgeon.
It seems that the division of labor in laparoscopic surgery teams has both similarities and differences with traditional surgery.
Today's surgery was specifically for low rectal tumors, which were not easy to perform with laparoscopy. The students standing in the corner were looking forward to the technical experts performing miracles.
Liu Chengran, who continued to serve as an assistant, helped the surgeon to establish pneumoperitoneum and inserted a laparoscope into the patient's abdominal cavity.
...
...
The monitor immediately showed a color image of the patient's abdominal cavity. The laparoscope shows the outside of the intestine, which is different from the digestive endoscope, so the patient's intestines were faintly moving.
The laparoscope was then handed over to the surgeon for abdominal exploration. Like traditional surgery, the purpose of the exploration was to determine whether the tumor could be removed and how much needed to be removed.
Holding the laparoscope, Tan Kelin looked at the monitor screen and said to someone behind him, "Stand up a little."
The surgeon's every move attracted everyone's attention.
All the students in the operating room heard the surgeon calling for someone to come up, and then saw Xie Wanying walk up and watch the monitor screen with the surgeon.
The students immediately exploded:
"who is she?"
"Resident?"
"He's a doctor from this hospital, I think."
"It can't be a trainee or an intern."
"Female doctor?"
"Why was a female doctor called up by Dr. Tan?"
One by one, they were whispering to each other, forgetting the order to keep quiet, apparently quite stimulated by the scene.
Luo Yanfen, Li Wenhao and the other three were even more stunned: What does the teacher want this rookie to do? The problem is that they don't think that such a young Xie Wanying has enough clinical skills to be able to do what Tan Kelin asked her to do.
"Get out if you keep talking!" Sun Yubo turned around and yelled impatiently at those who were talking.
When did the silent operating room turn into a vegetable market?!
All the noise stopped in a second.
The operating room returned to dead silence.
The students' attention returned to the progress of the operation.
The monitor screen showed the scene of the laparoscope perspective moving in the patient's abdominal cavity. Sometimes the picture changed very quickly, and sometimes it changed slowly.
Without a teaching demonstration and a teacher to explain, it would be difficult for students to fully understand what is happening on the screen.
Luo Yanfen and Zhang Zhongqiang asked Li Wenhao, who was in charge of bed 7, with inquiring eyes: Have you seen anything?
Li Wenhao shook his head.
