   You can use an ordinary electric drill or a primitive hand drill. The most important thing is the doctor\'s feel. This part is something that only a specialist surgeon with experience in playing through anatomy in the operating room can do.

   Xin Yanjun, a physician, can\'t do this feeling. Fortunately, medical tools are now advanced, and she can use medical tools to perform these operations. Medicine to better serve patients is absolutely inseparable from the development of physician tools.

  The emergence of advanced tools can lower the technical threshold of some doctors. Saving people depends on the efforts of more doctors, and it is necessary to lower the technical threshold. Just like when I didn\'t dare to use an electric drill before, a hand-cranked drill could make a male doctor soft, and an ordinary female doctor wouldn\'t even think of drilling a hole if he didn\'t have the strength to do so. Previously, the drainage operation could only be done by drilling the skull, requiring step-by-step incision of the skullcap and periosteum followed by puncture. Where as the tools are now developed, punching a cone hole cannula can solve the problem, which is called cranial cone puncture.

The threshold of    is lowered, but in the end it depends on specialist knowledge. Where to drill is the problem. Fortunately, there is a very special student around to help. Xin Yanjun continued to let the students assist him.

The student said it was okay, she took a scalpel and tapped it on the scalp, instead of making a long incision, she only needed to poke the knife and tap it out, and then use an electric drill equipped with a special device to make a small hole, cranial cone puncture. Basically half done.

   The prepared puncture needle was held in Xie Wanying\'s sterile gloved palm, which was a bit heavy. She wanted to put down the puncture needle instead of Teacher Xin.

  The medical staff around Xuanwu watched with their eyes fixed and dizzying.

   I saw that after the doctor in the department of respiratory medicine really did it, the next intern in the hospital was so courageous that he took the puncture needle without hesitation. Can interns have the feel of a specialist? Can you feel where the needle is going to stop?

   All to doubt this. Xiao Yang and Dr. Wang aimed their four eyes at the hand that Xie Wanying had descended, knowing that this would be the moment that would decide the life and death of the National Association.

  Xin Yanjun and Yue Wen held their breaths together, as if they were helping Xie Wanying to gain strength. Success or failure now rests on Xie Wanying\'s hands.

   Down, down again, Xie Wanying narrowed her eyes, her skull was covered, she could never see where the needle could go. It can only be done with preliminary CT images and a three-dimensional anatomical map formed in her brain.

   According to her guess, the depth is about 5.3 centimeters, and the direction is slightly to the right five degrees. Let the brain instruct her right hand holding the needle to carefully turn the direction to reach the predetermined three-dimensional coordinate point.

   There is a slight breakthrough feeling, and the information is transmitted from the needle tip to the nerve in her hand and then back to her brain: Is that right?

  In the operating room of the National Association, it was very quiet on the other side of the phone, and it could be seen that the person on the opposite side was in a critical operation. Cao Yong\'s hearts were suspended in mid-air, as if they were about to collapse at any time.

   Li Chengyuan secretly changed his breath, squeezed his phone tightly, and hesitated between opening and not opening.

   Can Little Junior Sister succeed? Huang Zhilei\'s brows twitched and picked, and he didn\'t dare to think about it for a moment.

  Lin Hao\'s face was like a ball of paper that was about to crumple. I hope the monitor and classmate Xie can stand on the opposite side.

   Persistence, must persevere. Everyone here knows clearly that the success of the rescue requires the persistence of the medical staff and the persistence of the injured person\'s own vitality.
