Chapter 1948 【1948】The Focus of the Second Half

The operation continued without any sign of being disturbed by the few words they had chatted. Doctor Liu was terrified. Except for Dr. Liu, the chief surgeon and the second assistant seemed unaware of the presence of outsiders.

This level of focus is a powerful thing.

Looking at it again, people outside the operating table, like Cao Yong and Tao Zhijie, were not disturbed by the crowd behind them, and their attention was focused on the operation without being distracted. Among the group of orthopedic surgeons behind, there was only one person talking to Ren Chongda. If the others didn't hear them, they were all focused on the operation.

Thinking about the shocking results brought about by the previous operation, everyone knew that this operation would be extremely exciting and perhaps it could be included in the classic cases of orthopedics.

Removing the bone is the focus of completing the first half of the operation, and will soon reach the focus of the second half of the operation. Removing a piece of bone is equivalent to breaking the spine. This phenomenon is like a broken bridge deck and piers that can no longer be used. Now that the doctor wants to find a way to fill in the defect, he has to take out the materials Xie classmate and the others visited in Chang Jiawei's office the day before yesterday.

The human body is like a machine, if any original parts are broken or missing, we can only find other ones to replace them. The artificial vertebral body that the doctor tried to create is an external part that needs to be considered, and if possible, look for similar parts of its own. For dental work, even if the tooth is too missing, the doctor will always try to keep the root of the tooth and put a crown on it. Humans and machines are as original as the best, and it is a last resort to replace them with other materials.

I talked about several artificial vertebral bodies that day, and today the doctor chose the titanium cage commonly used in clinical practice as usual. As I mentioned last time, the titanium cage may be the simplest equipment, but the most advanced one is difficult to adjust by itself. It is better to rely on the doctor's brain and hand skills to adjust it. The length of the titanium cage can be cut by the doctor according to the needs of the patient, and can be as long as desired. The determination of this length depends on the doctor's brain again.

Doctors have been doing the work of measuring equipment long before the operation based on CT scans and other imaging data combined with clinical examination. During the operation, the doctor probably had a spectrum of this in mind. It's just that this length must be estimated first, and then fine-tuned after surgery.

The length of the titanium cage is not only based on the length of the defect after removing the diseased bone, the doctor needs to refer to other factors. Take out the titanium cage, and as long as you see that its interior is hollow, you will understand that this thing is much more than just the appearance. Why not make it solid, because the bones and bones should be filled in the hollow heart.

Filling the gaps in the human body is not like filling in the gaps in the objects imagined by outsiders. The human body is full of living cells and not dead objects. One of the most important characteristics of living organisms is that they can continuously metabolize their life. The professional term is tissue cell regeneration, and in layman's terms it is called growth.

Doctors need to effectively use this vitality to help the human body restore health, instead of copying the set of repairing dead things mechanically. It may be botany that can be referred to. Seeds are sprinkled into the soil to allow them to grow. This principle can be called value-bone fusion in orthopedics. The transplanted bone tissue is placed in the defective bone environment for filling, allowing its cells to regenerate naturally and then fuse with the original bone tissue. In the same way, the titanium cage is loaded with bone blocks for filling, so that the bone cells regenerate and the original bone becomes a new fusion.

Don't think that a bone that is hard but not soft is a dead thing.
