Chapter 1943 【1943】Where Is the Basis
The hand of the neurosurgeon needs to be stable most, because once the nerve is affected, it cannot be repaired.
Xie Wanying also thought the same way, and said to her seniors: "I think Teacher Chang can do this kind of movement with precision."
Another characteristic of Xie is his sweet mouth. Seeing how natural she is in complimenting others, no matter how confident she is, she will blush unconsciously. Chang Jiawei didn't dare to move anymore, only he knew that his heart was going to hit his chest wall.
Seeing that the chief surgeon might refer to her opinion, Dr. Liu asked her, "What is the basis for your conclusion?"
"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 condition permits, the members of the surgical team debate halfway through the new difficulties discovered 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 occurred for the time being. It may be true as Tao Zhijie said. The abnormality of this playboy is all due to the guidance of classmate Xie.
"We know it's an ultrasonic bone knife." Dr. Liu responded to her.
"Ultrasonic bone knife uses vibration to break bones instead of cutting with a blade. The strength of the concentrated damage point can be greater than that of a simple blade. The target is the bone, and the bone is not soft tissue. Unlike soft tissue, it needs to be cut and torn slowly. Find the breaking point and focus on attacking, and it can be broken." 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, "Our teeth bite something that is too hard, and if it hits a bad point, it will crack. As for the ultrasonic bone knife, it can also be used in dentistry, teacher. "
Hearing what she said clearly and logically, Dr. Liu and other doctors around were silently thinking about the possibility of what she said.
The structural composition of teeth is definitely not exactly the same as that of vertebrae, but there are similarities, and there are also calcium, phosphorus and other minerals in the composition. As long as there is enough external force, hard objects can be broken. This kind of external force is either a destructive force, or it may not be strong enough to hit a weak point of the target to break it. This weak point may be the inherent weakness of the target's own structure, or it may be caused by disease or trauma.
"How did you come to the location of this damage point?" Dr. Liu further asked Xie's inference, which must be fully confirmed that the knife can be used.
The others listened in silence. According to the theoretical basis just mentioned, it is concluded that such a vulnerable point can exist, but how to determine the position of this point is a difficult problem.
Can you see it with your eyes?
In the intraoperative visual field, the bones and flesh are indistinct, non-red and heterochromatic parts or places invaded and destroyed by tumors. Usually, it is not easy to find the weak point of a normal bone. If the part of the tumor is added, it needs to be comprehensively considered to prevent the tumor from spreading, which is even more difficult.
Dr. Liu tortured her because she didn't think her prediction had an accurate basis.
Xie Wanying said to the teacher: "Mr. Liu, let me look at the monitoring data. I found that when the tip of Mr. Chang's knife touched the current place, the data showed signs of fluctuation. According to calculations, I guess that moving down a little bit should be the weak point. "
