A special bandage is soaked in slaked lime. At this time, the plaster bandage is soft. Only in this way can it be tied or applied to the relevant parts of the patient for shaping, and then the slaked lime hardens for fixation...
For another example, how many outsiders know that plaster bandages can be used not only for fracture treatment and correction, but also for burns?
Where is the plaster used in spinal surgery? Does the plaster bandage fix the spine?
Yes, plaster bandages can be used to bind the waist to fix the lumbar support, but care must be taken not to restrict the patient's chest breathing, and it is contraindicated for pregnant women. As for the current use of plaster bandages in the operating room, the scene of plaster use has changed.
, it becomes the operating bed where the patient lies during surgery, euphemistically called the plaster bed.
The plaster bed is hard and solid. When the patient lies on it, it is equivalent to the human bones being on the same plane, which is convenient for the orthopedic surgeon to observe and judge the position and angle of the bones. For example, in the posterior spine surgery to be performed today, the patient lies on the plaster bed.
In the prone position, the spine is supported by the plaster bed, which can better expose the surgical field.
The operating room nurse helped the doctor adjust the patient's position and immobilize the patient. Anesthesia was also done.
Dr. Liu brought classmate Xie in and sterilized and spread the drapes before surgery just like other surgeries.
While assisting Dr. Liu in pre-operative preparations, Xie Wanying discovered that classmate Geng did not show up. It might be that Geng Yongzhe couldn't bear the sight of his younger brother lying on the operating table, or that Geng's mother was crying outside and needed comfort from his eldest son, so she delayed arriving.
Orthopedic surgery is said to be more special than other surgeries. It involves bones, and the first image that comes to mind is that the doctor is like a butcher using a knife to chop bones in a slaughterhouse.
What is right here is that orthopedic surgeons do need to process human bones during surgery. They need to use a knife to cut bones. A knife that can cut bones must be like a knife in the kitchen. An ordinary knife cannot cut bones.
A special knife is required. This kind of knife is called an ultrasonic osteotome in orthopedics.
What does the ultrasonic bone knife look like? Is it as big as a bone chopping knife? No, the ultrasonic bone knife is similar to an ordinary electric knife, with a pen shape, except that the blade surface of the blade is larger than that of the electric knife. Don’t underestimate this
The appearance of the scalpel is not much different from that of a small knife. The principle of the ultrasonic bone knife uses high-frequency ultrasonic oscillation to destroy bones with a force that is absolutely comparable to that of a bone chopping knife.
Not only that, the ultrasonic osteotome can adjust the working frequency. Under a certain frequency limit, it can simply perform mechanical damage on bones with high acoustic impedance and calcified and mineralized hard tissues. At the same time, it can automatically screen out soft tissues with low acoustic impedance to avoid
Injury to soft tissue only attacks bone lesions. In spinal surgery, anatomically bones and nerves are closely related and always go hand in hand, which requires doctors to pay special attention during surgery. Ultrasonic osteotome cannot cut soft tissue, and orthopedic surgeons can avoid accidental nerve injury.
There are no sequelae, so the ultrasonic osteotome is a good baby.
The nurse's instrument table has a row of ultrasonic bone scalpel heads, and the doctor can choose to switch the blades. In addition to the ultrasonic bone scalpel, other conventional scalpels and electrosurgical scalpels are necessary. The assistant lays out the surgical drape.
The surgeon finished brushing his hands and entered the operating room.
"Dr. Zhang, I'm sorry to trouble you today." Chang Jiawei put on the surgical gown with the help of the nurse and said to the anesthesiologist.
