Fixed retractors have long been available in every department, but they may be seen more in orthopedic operating rooms than in other surgeries.
The main reason may be that the surgical area of orthopedics is relatively fixed. Unlike general and gynecological surgeries that are performed in the abdominal cavity, due to the limited scope of the large incision in the abdominal cavity, the doctor needs to explore other organs to adjust the surgical area, and the retractor needs to be moved around to coordinate. It cannot be said here that fixed retractors cannot be used in abdominal surgery, but it is just that ordinary doctors do not find it troublesome to adjust them around.
The medical students at Lagou are free human resources. They can respond flexibly to orders and save time effectively.
Since orthopedics requires fixation and does not need to be too flexible, using manpower may become a disadvantage at this time. In any case, classmate Xie Wanying can save her energy. Thinking about it again, since orthopedics is a department with heavy manual labor, the more labor-saving tools the better.
The operation is about to enter a critical stage.
Dr. Liu followed the surgeon's instructions and put the fixed retractor into the surgical field to stretch it to a certain angle and tighten the screws. After placing a fixed retractor on the upper and lower edges of the knife, Xie Wanying could accept the teacher's instructions to pull out her own manual retractor, put the suction device in her hand, and continue to assist the teacher in her work.
The surgical field in front of me was bloody and bloody. Unlike abdominal surgery, the bones were mainly exposed. This scene suddenly seemed more cruel. It was a bit like the feeling of being cut to the bone in a slaughterhouse. It was shocking. It's better not to think about it. If you think about it more deeply, the newly arrived medical students will probably be unable to swallow their food again after seeing this.
The surgeon's job is to make it difficult for people to eat, no matter which department they are in.
The surgeon on the stage must control his thoughts from thinking about the food on the table, must change his thinking from a picture to a drawing of the human body, and think about ergonomics instead of the stuff in the slaughterhouse. To develop this kind of mental inertia that does not affect eating, surgeons must work more and practice more.
The chief surgeon and his assistant both stopped and thought about it before preparing to repair the human bones.
The X-ray film is then taken out and hung on the light board in the operating room. The doctor compares the imaging film with the current surgical scene to accurately review the location of the diseased vertebrae. No problem, the surgeon shouted again: "Knife."
The instrument nurse handed over the electrosurgery.
Squeak, keep cutting, the sharp tip cuts the small muscles and ligaments around the bones, exposing the transverse processes of the vertebrae.
The diagrams in the anatomy textbooks can show the bones cleanly, but it is impossible to see clean bones during surgery. The bones of the human body are more like rusty iron blocks, covered with various things from all directions. The package is definitely full of blood and flesh. If you want to remove them cleanly, you will have to apply chemicals when putting them in the autopsy room for specimen preparation.
In order to distinguish the details of the bones in the blur of blood and flesh, the doctor could only rely on experience and a pair of super good eyes. Once again, it was confirmed that the bone to be treated was not treated. The electrosurgical knife was replaced with a periosteal stripper and the soft tissue around the transverse process was continued to be cleaned.
The transverse processes connect the rib joints to the ribs. If you want to remove the entire diseased vertebra, there is no doubt that the connecting ribs need to be broken first, and the broken rib stumps should be smoothed to avoid puncturing the pleura.
Use rongeurs to break the transverse process and rib scissors to break the ribs. All are hard tools like vise for repairing machines.
