  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 range of large incisions in the abdominal cavity, the doctor needs to explore other organs in the middle to adjust the operation area, so the retractor needs to be moved around for cooperation. It cannot be said that the fixed retractor cannot be used in abdominal surgery at all, but generally doctors do not feel that it is more troublesome to adjust it.

  Medical students with pull hooks are free human resources, and they can effectively save time by obeying commands and responding flexibly.

  Orthopedics need not be too flexible for fixation, and manpower may become a disadvantage at this time. In any case, Xie Wanying can save her energy. Think again, because orthopedics is a heavy manual labor department, the more labor-saving tools are invented, the better.

  The surgery is about to enter the critical stage.

   Dr. Liu followed the command of the chief 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 top and bottom of the knife edge, Xie Wanying could accept the teacher\'s instructions to pull out her own human retractor, put on the suction device in her hand, and continue to assist the teacher in her work.

   The surgical field in front of me was **** and bloody. Unlike abdominal surgery, the main exposed bones were the bones. This scene suddenly seemed more cruel. It is better not to think about it. If you think about it in depth, the medical students who have just arrived may not be able to swallow their meals again when they see this time.

  The job of a surgeon is to make it hard to eat, no matter which department is the same.

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

   The main knife and assistant both stopped, pondered, and then prepared to repair the human bones.

The   X-ray film is taken out and hung on the light board in the operating room. The doctor can accurately check the location of the diseased vertebra by comparing the current surgical screen with the imaging film. No problem, the main knife shouted again: "Knife."

   The instrument nurse handed over the electrocautery.

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

The pictures in the anatomy textbook can make the bones clean. It is impossible to see clean bones during surgery. The bones of the human body are more like rusted iron blocks that are covered in all directions by various things. The package is absolutely blood and flesh. If you want to remove it cleanly, unless you put chemicals in the dissection room for specimens.

   In order to distinguish the details of the bones in the **** flesh, the doctor can only rely on experience and a pair of super good eyes. Once again, it was confirmed that the bone to be treated was not done, and the electrocautery was replaced with a periosteal peeler to continue to clean the soft tissue around the transverse process.

The    transverse process connects the rib joints to the ribs. If the entire diseased vertebra is to be removed, there is no doubt that the connected ribs need to be broken first, and the stumps of the broken ribs are trimmed to avoid puncturing the pleura.

   Use rongeurs to break the transverse process, and use rib scissors to break the ribs. It\'s all about hard tools like a vise to fix a machine.
