Doctors' vision can be used to their advantage with the help of microscopes, but microscopes cannot help doctors perform delicate operations with their hands. What can assist doctors' hands is surgical robots, which medicine is working hard to research and develop.
Sitting in the surgeon's chair, Xie Wanying held the instruments with both hands.
Because the surgical field is very small, neurosurgery is often performed by the surgeon alone, which is similar to pediatric surgery.
Neurosurgery assistants can only do some very general assisting actions, usually rough operations without even using a microscope, unless the surgeon asks the assistant to take a look through the operating microscope.
The main reason is this: the main eyepiece and assistant eyepiece of the microscope can only be combined into one due to the space limitation above the surgical field. When the microscope is moved, the main eyepiece must be used as the main focus, and the assistant eyepiece cannot be moved randomly. Under this condition, the assistant can only adjust the magnification of the assistant eyepiece when the field of vision is unclear most of the time, resulting in very limited operations that the assistant can perform through the microscope.
The operation mainly relies on the surgeon, so the pressure naturally falls on the surgeon alone. The surgeon's eyes look through the surgical microscope, magnifying more than just the surgical field, including the surgeon's own hands.
Every small movement of your hand will turn into a large movement under the microscope.
To use a simple analogy, if most pediatric surgeries are performed by centimeters and a few millimeters, then too many neurosurgeries are performed by millimeters or even less than a millimeter. This is enough to show that microscopic surgery is far more difficult than surgery under a surgical magnifying glass.
It was her first time to perform surgery under a microscope. Just looking at the surgical field under the microscope and her hands in sterile gloves, the heart rate of a doctor with poor stress tolerance would probably accelerate to hundreds of times. Before she knew it, Xie Wanying was breathing softly.

She adjusted her breathing rhythm, hoping to relieve her mental tension. This daily decompression action might be useful in ordinary situations, but it was hard to say for special situations. Soon she found that the adrenaline she could relieve within two seconds was only as long as her eyes were focused on the microscope again, and the tension in her brain soared again.
It must be admitted that surgery under a microscope requires a more special kind of hand-eye coordination, which cannot be developed overnight. Microscopic surgery is only performed in some surgical departments (for example, neurosurgery, ophthalmology, and otolaryngology), and is rarely used in general surgical departments such as general surgery, and some departments do not use it at all.
As a result, most medical students do not have the opportunity to practice in these special departments. Xie Wanying is no different from other medical students in this regard.
The current predicament cannot be unexpected.
She was reborn, and she was aware of the high difficulty of neurosurgery. Otherwise, she would not have dared to do it as she said before, but would have hesitated a little, really not sure and lacked confidence.
The first assistant is always the one who can best understand the surgeon's condition. Cao Yong, who was sitting on her left, was facing the assistant tube of the surgical microscope. While observing the situation inside the bone window with her, he asked her, "Are you scared?"
Senior Brother Cao is her assistant and also a clinical instructor. When he is a teacher, Senior Brother Cao is very serious and strict. As a neurosurgeon, Senior Brother Cao is also like many other surgical experts who don't like to make any noise during the operation. He doesn't make any noise unless it is necessary, so as to concentrate his attention.
