It is to soak a special bandage with slaked lime. At this time, the plaster bandage is soft, and only in this way can it be tied or applied to the relevant parts of the patient for shaping, and then wait for the slaked lime to harden and play a fixing role.
For example, how many laymen know that plaster bandages can be used for burns in addition to the most commonly used fracture correction treatment?
Where is the plaster used in spinal surgery? Does the plaster bandage fix the spine?
Yes, plaster bandages can be used to tie the waist for lumbar support, but be careful not to restrict the patient's chest breathing, and it is contraindicated for pregnant women. As for now in the operating room, plaster bandages are temporarily unavailable, and the scene of plaster application has changed. It has become the operating bed on which the patient lies during surgery, which is called a plaster bed.
The plaster bed is hard and solid. When the patient lies on it, the human skeleton is on a flat surface, which is helpful for orthopedic surgeons to observe and judge the position and angle of the bones. For example, in the posterior spinal surgery to be performed today, the patient is in a prone position on the plaster bed, and the spine is propped up by the plaster bed, which can better expose the surgical field of view.
The operating room nurse helped the doctor adjust the patient's position and immobilize the patient. Anesthesia was also given.
Doctor Liu brought Xie in and performed the disinfection and draping before the operation, just like any other surgical operation.
While assisting Dr. Liu in the preoperative preparations, Xie Wanying discovered that Geng had not shown up. It was possible that Geng Yongzhe could not bear to see his brother lying on the operating table, or that Geng's mother was crying outside and needed his eldest son's comfort, so he had not shown up yet.
Orthopedic surgery is said to be more special than other surgical operations because it involves bones. The first image that comes to people's mind is that the doctor is like a butcher chopping bones with a knife in a slaughterhouse.

What is not wrong here is that orthopedic surgeons do need to process human bones during surgery, and they need to use knives to cut bones. The knives that can cut bones must be like the knives in the kitchen. If you just use ordinary knives, you can't cut bones. You need special knives. This kind of knife is called an ultrasonic bone knife in orthopedics.
What does an ultrasonic bone scalpel look like? Is it as big as a bone-chopping knife? No, the ultrasonic bone scalpel is similar to an ordinary electric scalpel, pen-shaped, but the blade of the blade is larger than that of an electric scalpel. Don't underestimate this scalpel. It is a small knife. The principle of the ultrasonic bone scalpel is to use high-frequency ultrasonic vibration to produce a force that can definitely compare to a bone-chopping knife in destroying bones.
Not only that, the ultrasonic bone scalpel can adjust the working frequency. Under a certain frequency limit, it can only mechanically destroy bones with high acoustic impedance and calcified and mineralized hard tissues, while automatically screening out soft tissues with low acoustic impedance to avoid damaging soft tissues and focus on attacking bone lesions. In spinal surgery, bones and nerves are closely related in anatomy and always go hand in hand, so doctors need to pay special attention during surgery. If the ultrasonic bone scalpel cannot cut soft tissue, orthopedic surgeons can avoid accidentally injuring nerves and prevent postoperative sequelae. Therefore, the ultrasonic bone scalpel is a good baby.
The nurse's instrument table has a row of ultrasonic bone knife heads, allowing doctors to choose and switch the heads. In addition to ultrasonic bone knives, other conventional scalpels and electric knives are required. The assistant spreads the surgical sheet.
The surgeon washed his hands and entered the operating room.
"Doctor Zhang, thank you for your help today." Chang Jiawei put on his surgical gown with the help of the nurse and said to the anesthesiologist.
