Returning to ’90s, She Became Famous in Major Surgical Fields

   Chapter 1943 [1943] Where is the basis

  The neurosurgeon's hand is the most stable, because once the nerve is affected, it is irreparable.

   Xie Wanying thought the same way, and said to the senior: "I think Teacher Chang can do this kind of movement with precision."

Another feature of   Xie is his sweet mouth. Just seeing her compliment is very natural, and even the most confident person will blush unconsciously. Chang Jiawei didn't dare to move anymore, only he knew that his heartbeat was about to hit his chest wall.

  Doctor Liu saw that the chief surgeon might refer to her opinion and asked her, "What is the basis for the conclusion you just drew?"

   "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 allows, the members of the surgical team debate on the basis of new difficulties discovered during the operation, in order to adjust 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 abnormality had occurred for the time being. It may be as Tao Zhijie's Buddha said, the playboy's abnormality is all due to Xie's guidance.

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

"Ultrasonic osteotome uses vibration to break bones, rather than cutting with a blade. The force on the concentrated damage point can be greater than that of a simple blade. The target is bone, and bone is not a soft tissue. Unlike soft tissue, it needs to be slowly cut and torn. Find the breaking point and focus on attacking, you can break it 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, "My teeth bite something that is too hard. If it hits a bad point, it will crack. As for the ultrasonic bone knife, it can also be used in dentistry, teacher. ."

  Ear listened to what she said, Dr. Liu and the other doctors around were silently thinking about the possibility of what she said.

  The structural composition of teeth and vertebrae are definitely not exactly the same, 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 cracked. This external force is either a destructive force, or the force may not be heavy enough to hit a vulnerable point of the target and break it. This vulnerable point may be the inherent weakness of the target's own structure, or it may be caused by disease or trauma.

   "How did you figure out the location of the damage point?" Dr. Liu further asked Xie's inference that it must be completely confirmed that the knife can be used.

  Others listened quietly. According to the theoretical basis just mentioned, it is concluded that such a vulnerable point can exist, but how to determine the location of this point is a difficult problem.

   Can you see it with your eyes?

   The field of vision during the operation is the blurred bone and flesh, the non-red part with a different color, or the part occupied and destroyed by the tumor. Usually, it is not easy to locate the vulnerable point of a normal bone. If the tumor part is added, it is necessary to comprehensively consider to prevent the tumor from spreading when the knife is cut, which is even more difficult.

   Dr. Liu tortured her because she did not think her prediction could have an accurate basis.

Xie Wanying said to the teacher: "Mr. Liu, let me see the monitoring data. I found that when the tip of Teacher Chang's knife touched the current place, the data showed signs of fluctuation. According to calculations, I estimate that moving down a little should be the vulnerable point. "
