Fixed retractors have been around for a long time and are 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 surgery and gynecological surgery, which are located 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, so 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 most 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 require too much flexibility, using manpower may become a disadvantage at this time. In any case, Xie Wanying can save energy. Thinking about it again, since orthopedics is a department with heavy manual labor, it is best to invent more labor-saving tools.
.
The operation is about to enter a critical stage.
Dr. Liu followed the instructions of the surgeon, put the fixed retractor into the surgical field, stretched it to a certain angle, and tightened the adjustment screws. After placing a fixed retractor on the upper and lower sides of the knife edge, Xie Wanying could accept the teacher's instructions to pull out her own manual retractor and replace it in her hand.
The suction machine is on, and I continue to assist the teacher in his 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. I don’t want to compare.
Well, 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 job of a surgeon 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 and not think about the food on the table. He must change his thinking from pictures to drawings of the human body, and think about ergonomics instead of things in the slaughterhouse. He must develop this kind of thinking that does not affect eating.
For surgeons, inertia must be acquired by working more and practicing more.
Gu AiThe surgeon and his assistant both stopped and thought about it before preparing to repair the human bones.
The X-ray films are then taken out and hung on the light board in the operating room. The doctor compares the current surgical images with the imaging films to accurately review the location of the diseased vertebrae. When there is no problem, the surgeon calls again: "Knife."
Instruments The nurse handed over the electrosurgery.
Squeak, keep cutting, the sharp tip cuts off 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 must contain blood and flesh. If you want to remove it cleanly, you will have to apply chemicals when putting it in the autopsy room for specimen preparation.
In order to distinguish the details of the bones in the blurred 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, so the electric knife was replaced with a periosteal stripper and continued to clean out the area around the transverse process.
of soft tissue.
The transverse process connects the rib joints and 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 puncturing the pleura.
Rongeurs are used to break the transverse process, and rib scissors are used to break the ribs. All require hard tools such as vise for repairing machines.
