?? Chapter 1950 [1850] Participation
??If there is no autologous bone, you can use allogeneic bone instead, that is, use someone else's bone. Just definitely no autologous bone is best.
??The doctor took a small medical stainless steel cylindrical jar, which contained broken bones and artificial bone particles, and stirred them to mix.
??Artificial bone is a piece of artificial bone, which is added with other mechanical properties such as collagen to the mineral component, so that the biological material is more in line with the mechanical structure of the human body.
?? This kind of manual work is suddenly reminiscent of a decorator.
?? Of course, the manual work of doctors is much more advanced. Without a solid accumulation of medical knowledge, medical manual work cannot be supported at all. After all, human life and dead things are different, they are always in motion, and the risks remain high. The storage knowledge capacity and computing power of an excellent doctor's brain are comparable to those of an ordinary decorator, just like the difference between a supercomputer and an ordinary computer.
??Insert the titanium cage and fill the bone fragments. The serrations at the upper and lower ends of the titanium cage mixed with the autologous bone are embedded in the upper and lower vertebral bodies for fixation, preventing them from moving. To be on the safe side, the doctor will add a nail rod system on this basis for reinforcement.
??The job of a decorator is back. It's like how to put a nail in the wall at home. Bone is like a cement wall. First, use a hammer to make holes in the pedicles on both sides of the upper and lower vertebrae, then drill the holes, and then screw them with self-tapping screws. Rely on these screws through the middle of the metal rod for reinforcement on both sides.
?? These are all proper physical labor. Fortunately, like decorating at home, if there are tools, it lowers the threshold for women to get started. This is the same as the electric skull drill outside the nerve.
?? The principle of the above operation process is understood, and Xie Wanying can start to use her ability to assist the main surgeon when cutting the length of the titanium cage. With the previous knife showing her extraordinary computing power, they now believe in the parameters she provides.
?? "It needs to be a little shorter." Xie Wanying estimated.
??The surgeon will move and cut according to the length she refers to.
??Doctor Liu couldn't see how the difference was calculated. He only knew that maybe this difference would work like a miracle just now, and he would no longer foolishly torture classmate Xie. Besides, there is a master knife in check.
?? After cutting, fill the orthopedics into the hollow of the titanium cage. How much is filled is also a skill. Moderate padding is most important. This proportion can only be estimated by doctors as well.
?? This operation is relatively simple. After the main knife demonstrates it, I simply let Xie do it.
?? The group of people around continued to watch secretly, thinking that this **** dared to let go like this. Could it be that he really treats girls more favorably.
??Holding tweezers, Xie Wanying carefully clamped the autologous bone and artificial bone piece by piece into the titanium cage. When placing it, all parts should be evenly pressed, just like leveling the soil, to make sure that the seeds are fully mixed in the soil.
?? After this step is completed, put on the nail rod system.
?? Make a hole at the position of the pedicle, which position is better, Xie will draw again.
The people behind ?? watched here and had to think about who the teacher was.
?? The truth is, these little bits may only have a difference of one or two millimeters and a slight angle deviation. On weekdays, other orthopedic surgeons must ignore them when they perform surgery, and give an estimate. It is all with the naked eye, and it is difficult to see and estimate the distance of a single point millimeter. Most doctors cannot calculate the difference after the decimal point like a computer.
