A doctor's vision can be taken advantage of with the help of a microscope, but the microscope cannot help the doctor's hands perform fine operations. What can assist the doctor's hands is the surgical robot that medicine is working hard to research and develop.
Sitting on the surgeon's chair, Xie Wanying held the instrument with both hands.
Due to the tiny surgical field, neurosurgery is often performed almost by the surgeon alone. This is similar to pediatric surgery.
Neurosurgery assistants can only do very general manual movements on the side, usually rough operations without even using a microscope, unless the chief surgeon asks the assistant to use a surgical microscope to take a few glances.
The main reason is this: the main eyepiece and the assistant mirror of the microscope can only be integrated into one body due to the space limit above the surgical field. When the microscope is moved, the main eyepiece must be the main one, and the assistant mirror cannot move randomly. Under these conditions
Most of the time, the assistant can only adjust the magnification of the assistant's mirror when the field of vision is unclear, resulting in very limited operations that the assistant can do through the microscope.
The operation mainly relies on the surgeon alone, and the pressure naturally rests on the shoulders of the surgeon alone. The doctor's eyes, through the operating microscope, magnify far more than the surgical field, including the doctor's own hands.
Every movement of the hand will turn into a big movement under the microscope.
To use a simple metaphor, if most operations in pediatric surgeries involve movements of centimeters and a few millimeters, many neurosurgery operations involve movements of millimeters or even exaggerated movements of less than millimeters. This is enough to show that microscopic surgery is far more difficult than the detailed operations under a surgical magnifying glass.
.
The first surgeon to perform microscopic surgery only looked at the surgical field under the microscope and her own hands wearing sterile gloves. The doctor, who was not very good at handling stress, was expected to have his heartbeat accelerate to hundreds of times. Unknowingly, Xie Wanying was exhaling softly.
She was breathing at her own pace, hoping to relieve the mental tension. This daily stress-reducing action might be useful in ordinary situations, but it was difficult to say in special situations. Soon she discovered that the amount of adrenaline she could relieve in two seconds was only
When his eyes were aimed at the microscope again, the tension in his brain skyrocketed again.
It must be admitted that surgery under the microscope requires a more special kind of hand-eye coordination, which cannot be developed overnight. However, surgery under the microscope is only carried out in some surgical departments (for example, neurosurgery, ophthalmology and otology), and is not practiced in general surgery.
It is rarely used in general surgical departments, and is not used at all in some departments.
This situation has led to the fact that most medical students have not had the opportunity to be exposed to and practice in these special specialist departments. She, Xie Wanying, is no different from other medical students in this regard.
The current predicament cannot be unexpected.
She was reborn and was conscious of the difficulty of neurosurgery. Otherwise, she would not have dared to do it as she said before. Instead, she was a little hesitant, not really sure, and lacked confidence.
Yisuke was always the person who had the best insight into the situation of the surgeon. Cao Yong, who was sitting on the left side of her assistant position, was facing the assistant tube of the surgical microscope. While he and she were preliminary observing the situation inside the bone window, he asked her in a voice: "Are you afraid?"
?”
Senior Brother Cao is her assistant and clinical instructor. When he was a teacher, Senior Brother Cao was very serious and strict. As a neurosurgery expert, Senior Brother Cao was also like many surgical experts who did not like to keep silent during the operation.
It is necessary to be silent so that you can concentrate your attention.
