The neurosurgeon's hand needs to be steady, because once the nerve is affected, it cannot be compensated.
Xie Wanying thought the same way and said to her senior: "I think Teacher Chang can do such a move accurately."
Another characteristic of Classmate Xie is her sweet mouth. She praises others so naturally that no matter how confident she is, people will blush unconsciously. Chang Jiawei didn't even dare to move. Only he knew that his heartbeat was about to beat loudly.
to the chest wall.
Seeing that the surgeon might refer to her opinion, Dr. Liu asked her: "What is the basis for the conclusion you just made?"
"First of all, this is the ultrasonic osteotome, teacher." Xie Wanying turned back and continued the discussion with Teacher Liu.
When the patient's condition allows, members of the surgical team will debate based on the new difficulties discovered during the operation, with the purpose of adjusting a better surgical operation plan that is beneficial to the patient.
Zhang Tinghai walked back to the anesthesia machine and saw that the patient's vital signs were stable and no special abnormalities had occurred for the time being. Maybe it was just as Tao Zhijie said, and the playboy's abnormality was all due to the guidance of classmate Xie.
"We know it's an ultrasonic osteotome." Dr. Liu responded to her.
"The ultrasonic osteotome uses vibration to break bones instead of cutting with a blade. The force on the concentrated destruction point can be greater than that of a simple blade. The target is the bone. Bone is not a soft tissue. Unlike soft tissue, it needs to be cut and torn slowly. It only needs to be
Find the breaking point and focus your attacks, and it will break apart." Xie Wanying said.
"Is that so?" Dr. Liu expressed some doubts about what she said.
"It can be compared to teeth." Xie Wanying gave an example. "When our teeth bite something that is too hard, if they happen to hit a bad spot, they will break. As for the ultrasonic osteotome, it can also be used in dentistry, teacher.
"
Listening to what she said so clearly, Dr. Liu and the other doctors around him were silently thinking about the possibilities she said.
The structural components of teeth are definitely not exactly the same as those of vertebrae, but they are similar. They also contain calcium, phosphorus and other minerals. As long as there is enough external force, hard objects can break. This external force, either
The destructive force is either not strong enough but hits a vulnerable point of the target to cause it to break. This fragile point may be an inherent weakness in the target's own structure, or it may be caused by disease or trauma.
"How did you conclude that the location of the damage point is here?" Dr. Liu further asked Xie's inference. It must be completely confirmed before surgery can be performed.
Others were listening silently. According to the theoretical basis just mentioned, it is concluded that there can be such a vulnerable point, but how to determine the location of this point is a difficult problem.
Can you tell with your eyes?
The visual field during the operation shows the bones with blurred flesh and blood, non-red and heterochromatic parts, or places invaded and destroyed by tumors. It is usually not easy to find the weak points of a normal bone. If a tumor is added, it is necessary
Taking all the factors into consideration, it is even more difficult to prevent the tumor from spreading during the operation.
Dr. Liu tortured her because she didn't think her prediction had an accurate basis.
Xie Wanying said to the teacher: "Teacher Liu, please let me look at the monitoring data. I found that the data showed signs of fluctuation when the tip of Teacher Chang's previous knife came to this place. Based on calculations, I estimate that moving down a little should be the vulnerable point.
