Fixed retractors have been found in any department, but they may be seen in orthopedic operating rooms than in other surgical departments.

The main reason may be that the orthopedic surgery area is relatively fixed. Unlike general surgery and gynecology, which are located in the abdominal cavity, due to the limited scope of the large blade in the abdominal cavity, the doctor needs to explore other organs to adjust the surgical area, which causes the hook to be moved and cooperated. It cannot be said that the fixed retractor cannot be used in abdominal surgery at all, but ordinary doctors do not need to think that adjusting it over and over is more troublesome.

The medical students who are free of charge are very good. Following commands and responding flexibly can effectively save time.

Since orthopedics requires fixation and not being too flexible, the use of manpower may become a disadvantage now. In any case, Xie Wanying can save energy. Think about it again, because orthopedics is a heavy physical work department, the only way to invent labor-saving tools is to give more.

The operation is about to enter the critical stage.

Dr. Liu followed the command of the main surgeon and put the fixed retractor into the surgical field and stretched it to a certain angle to tighten the adjustment screw. After putting a fixed retractor up and down the blade, Xie Wanying could accept the teacher's instructions to pull out her human hook, change the suction device in her hand, and continue to assist the teacher in her work.

The vision in front of me is bloody and bloody. Since the bones are exposed differently from abdominal surgery, the scene suddenly seems more cruel. It is a bit like the feeling of seeing the bones with a knife in a slaughterhouse, which is shocking. It is better not to associate. If you think about it in depth, the medical student who just arrived probably won’t be able to swallow the food again when he sees it.

The work done by surgeons is that it is difficult to swallow food, no matter which department it is.

The surgeon on the stage must control his thoughts and not think about the food on the dinner table. He must change his thinking from the sense of picture to the human body drawings, and calculate the ergonomics rather than the things in the slaughterhouse. To practice this kind of thinking inertia that does not affect eating, for the surgeon, he must practice more work and practice more.

Gu Shin-span>The main surgeon and assistant both stopped, thought about it, and then prepared to repair the human bones.

Then take out the x-ray film and hang it on the lamp board in the operating room. The doctor used the current surgical picture to accurately review the location of the lesion vertebrae. No problem, the main surgeon shouted again: "Knife."

The nurse handed over the electric knife.

Squeak, continue to cut, and the sharp tip of the knife cuts the small muscle ligaments around the bone, exposing the transverse process of the vertebrae.

The pictures in the anatomical textbook can draw the bones cleanly. It is impossible to see clean bones during surgery. The bones in the human body themselves are more like rusty iron blocks, wrapped in all directions, absolutely covered with blood and flesh. If you want to remove them cleanly, unless you put them in the anatomy room for specimens to apply chemical agents.

In order to distinguish the details of the bones in the bloody and bloody blur, the doctor could only rely on experience and a pair of super good eyes. Once again, it was confirmed that the bone to be processed was not done. The electric knife was replaced with a periosteal stripper and continued to clean up the soft tissue around the transverse process.

The transverse process connects the rib joint and the ribs. If you want to remove the entire diseased vertebra, there is no doubt that the connected ribs need to be broken first, and the broken rib stumps should be smoothed to avoid puncture of the pleura.
