Chapter 1950 [1950] Participation

If there is no autologous bone, allogeneic bone can be used instead, that is, someone else's bone can be used. It’s just that it’s best not to have autologous bone.

Seeing the doctor took a small medical stainless steel cylindrical jar, which contained broken bone and artificial bone particles, and stirred it back and forth to mix it.

The artificial bone is made by adding collagen and other mechanical properties to the mineral components, so that the biological material is more in line with the mechanical structure of the human body.

This kind of manual work suddenly reminds people of decorators.

Of course, the manual work of doctors is much more advanced. Without a solid accumulation of medical knowledge, it is impossible to support medical manual work. After all, human life and dead things are different, they are always in motion, and the risks remain high. The knowledge storage capacity and computing power of an excellent doctor's brain are compared with that of an ordinary decorator, just like the difference between a supercomputer and an ordinary computer.

Put the bone into the titanium cage and fill it. The serrations at the upper and lower ends of the titanium cage mixed with autogenous 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 the decorator is back. It's like how to drive a nail into the wall at home. The bone is like a cement wall. First use a hammer to drill holes on the pedicles on both sides of the upper and lower vertebrae, then drill the holes, and then install self-tapping screws after drilling. Rely on the middle of these screws to pass through the metal rod for reinforcement on both sides.

These are all proper heavy physical labor. Fortunately, just like decorating at home, if there are tools, the threshold for women to get started is lowered. This is the same as the electric skull drill outside the nerve.

Now that the principle of the above operation process is understood, Xie Wanying can start to use her ability to assist the chief surgeon when cutting the length of the titanium cage. The previous knife showed her extraordinary calculation power, and the chief knife and the others now believe in the parameters she provided.

"It needs to be a little shorter." Xie Wanying guessed.

The surgeon moved and cut according to the length she indicated.

Anyway, Dr. Liu couldn't see how the difference in ideas was calculated, but he knew that the difference might be as miraculous as the one knife just now, and he wouldn't torture classmate Xie foolishly again. Besides, there is a master knife who will check.

After cutting, fill the orthopedics into the hollow of the titanium cage. How much to fill is also a skill, too full is not enough, and too empty is not good. Moderate filling is the most important. This ratio can only be estimated by the same doctor.

This operation is relatively simple. After the chief surgeon demonstrates it, let Xie do it.

The group of people around continued to watch secretly, thinking that this playboy dared to let go like this, could it be that he really treats girls more preferentially.

Holding tweezers in hand, Xie Wanying carefully clamped the autologous bone and the artificial bone into the titanium cage. When placing them, each part should be evenly pressed, just like leveling the soil, to ensure that the seeds are fully mixed in the soil.

After this step is completed, put on the nail rod system.

Drill a hole at the position of the pedicle, which position is better, Mr. Xie will draw again.

The people behind came to watch here, and had to think about who is the teacher.

The truth is, these little points may only have a difference of one or two millimeters in distance and micro-angle deviation, which must be ignored by other orthopedic surgeons when performing operations on weekdays, and give an estimate. It is all naked eyes, and it is difficult to see and estimate the distance of a few millimeters. Most doctors cannot calculate the slight difference after the decimal point like a computer.
