The neurosurgeon's hands need to be steady the most, because once the nerve is affected, it is irreparable.
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 that she has a 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 permits, members of the surgical team debate the new difficulties discovered during the operation in order to adjust 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 abnormality had occurred for the time being. Maybe it was exactly what Tao Zhijie said, and the playboy's abnormality was all due to classmate Xie's guidance.
"We know it's ultrasonic osteotomy." 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.
Valley side "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 point, they will break. As for the ultrasonic osteotome, it can also be used in
Dental, 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 this 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 intraoperative visual field shows blurred bones, non-red and heterochromatic parts, or areas invaded and destroyed by tumors. Usually it is not easy to find the weak points of a normal bone. If a tumor is added, it is necessary.
All things considered, 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, 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. According to calculations, I estimate that moving down a little should be the vulnerable point.
