A neurosurgeon's hand needs to be stable most, because it cannot be compensated once it affects the nerves.

Xie Wanying thought the same way and said to her senior: "I think Teacher Chang can do such movements and be accurate."

Another characteristic of classmate Xie is his sweet mouth. He only sees her praising people naturally, and even the most confident people will blush without realizing it. Chang Jiawei dares not move, only he knows that his heartbeat is about to hit the chest wall.

When Dr. Liu saw that the surgeon might refer to her opinion, he asked her: "Where is the basis for the conclusion you just reached?"

"First of all, this is an ultrasonic bone knife. Teacher." Xie Wanying turned around and continued to discuss with Teacher Liu.

When the patient's situation allows, the members of the surgical team debated halfway based on the new difficulties found during the operation, with the purpose of adjusting a better surgical operation plan, which 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 yet. It might be as the situation said by Tao Zhijie. The abnormality of this playboy was all due to the guidance of classmate Xie.

"We know it's an ultrasound bone knife." Dr. Liu responded to her.

"Ultrasound bone knife uses vibration to break bones, not cut with the blade. Its strength can be greater than that of a simple blade. The target is bones. The bones are not soft tissues, unlike soft tissues that need to be cut and tear open slowly. You only need to find the breaking point to attack in a concentrated manner, and you can break and crack it." Xie Wanying said.

"Is that true?" Dr. Liu expressed some doubts about what she said.

Gu Wei "It can be compared to teeth." Xie Wanying gave an example, "If our teeth bite something too hard, it will crack if we just hit a bad point. As for ultrasonic bone knife, it can also be used in dentistry, teacher."

Hearing her words, Dr. Liu and other doctors around him were silently thinking about the possibility she was talking about.

The structural components of teeth are definitely not exactly the same as vertebrae, but there are similarities, and calcium, phosphorus and other minerals in the components. As long as there is enough external force, it can cause the hard object to collapse. This external force is either a destructive force, or it may not be heavy, but it can just hit a target with a fragile point of weakness to break. This fragile point may be the inherent weakness of the target object's own structure, or it may be caused by diseases or trauma.

"How do you find out where this destruction point is located?" Dr. Liu further asked Student Xie's inference, and it must be completely confirmed that it is clear that the knife can be taken.

Others were listening quietly. According to the theoretical basis just now, it was to conclude that such a fragile point could exist, but how to determine the position of this point is a difficult problem.

Can you tell by your eyes?

The visual scene during the operation is a blurred bloody part of the bone, non-red and heterochromatic part or a place occupied and damaged by the tumor. It is not easy to find the location of a normal bone. If the part of the tumor is added, it is necessary to consider comprehensively prevent the tumor from spreading when the tumor is taken.

Dr. Liu asked her because she didn't think her trailer could have an accurate basis.
