It’s not surprising that orthopedics is a gathering place for strong men and women, and all these tasks require full strength.

Usually, senior Chang’s romantic and elegant appearance and Dr. Liu’s gentle appearance, who would have thought that they had broken bones during orthopedic surgery, like Popeye who ate spinach.

Speaking of external surgery, if it weren't for the development of thoracoscopy, traditional surgery also required broken bones. For this reason, Xie Wanying looked at the rib cut and thoughtfully tried to try it. The teacher on stage would not be able to give her this opportunity. She could only observe on-site how the seniors used tools to convey their power to quickly achieve their goals, and then study it myself. It would be necessary to ensure that they would not miss the opportunity next time they had the opportunity.

After cleaning up the tissue connected around the lesion thoracic vertebrae, the next step is to remove the entire lesion thoracic vertebrae from the human body. This is the first critical step in the entire operation. In the imagination of outsiders, the thing connected around the thoracic vertebrae can be removed, so naturally this thing can be pulled out, so why do you need anything else?

This is a illusion of not knowing human anatomy..

There is a foramen in the middle of the thoracic vertebrae, which connects to form a spinal canal. The central nervous system that controls the trunk and limbs: the spinal cord.

It goes without saying how important the spinal cord is to the human body. It can be said that without the spinal cord, the brain's signal to the body will have zero execution effect and the signal cannot be transmitted.

Gu JiuIf you want to separate the vertebrae and the spinal cord, you will not hurt the spinal cord, except to cut the vertebrae in half and cut it from the spinal cord. There is no other way. The foramen and the spinal cord are closely located, especially the diseased vertebrae. The tumor establishes a connection between the vertebrae and the spinal cord. All of this is very easy to injure the spinal cord. How to ensure that the bone cutting does not inadvertently damage the central nerve? The eyes cannot see clearly, so they can only rely on monitoring methods like fire alarms. Whenever there are signs of injury, the doctor immediately calls the alarm, and the doctor stops operating and avoids the alarm area. In spinal surgery, similar fire alarm monitoring is called neural electrophysiological detection. There are three commonly used types: monitoring SEP that monitors ascending sensory nerve conduction, commonly known as somatosensory evoked potential; monitoring the MEP that monitors downward motor nerve conduction as motor evoked potential; monitoring the nerve EMG electromyography that controls muscle activity.

The three monitoring projects have their own strengths, strengths and weaknesses. Of course, they should work together to improve their strengths and avoid weaknesses to form complementary advantages. The more data the doctor has, the more they can fully implement intraoperative monitoring, so that their surgical activities can be accurate to avoid accidental injuries.

The monitoring is all done. The main surgeon is busy with cutting and has no time to watch the monitoring screen as soon as possible. The assistant is responsible for reminding the main surgeon in time. Dr. Liu quickly told the students how to observe the data so that he could help him as soon as possible.

"Simply put, these monitoring and other monitoring items are similar. A rough judgment can be used to see the waveform. The large-scale changes and differentiation of the waveform must indicate that there is an abnormality in the situation." Dr. Liu said.

This is the significance of human invention of waveform charts. The ups and downs can make people's eyes quickly judge the abnormal changes in data most intuitively without the need for human eyes to carefully distinguish the changes in numbers one by one.
