In the operating room, Yang Ping instructed two instrumental nurses on how to cooperate: one was to specifically prepare the instruments for the next step, placing the required instruments for the next step in the most priority position. Yang Ping would inform her in advance to be ready, and she must listen attentively.
The other nurse was responsible for delivering instruments, taking the needed instruments from the priority position and delivering them as quickly as possible.
With the two working together in this way, the speed could be increased.
Once everything was ready, Yang Ping began to enter the cranium through the operation window in the eye socket, using the safety window to separate the tumor.
