is a special bandage soaked in slaked lime. At this time, the plaster bandage is soft, and only in this way can it be tied or applied to the relevant part of the patient for shaping, and then wait for the slaked lime to harden to fix it.

For another example, how many laymen know that plaster bandages can be used for burns in addition to the most commonly used fracture treatment and correction.

Where is the cast of spine surgery used? Do plaster bandages immobilize the spine?

Yes, plaster bandages can be tied to the waist for lumbar support, but be careful not to restrain 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.

The plaster bed is hard, and the patient lies on it as a whole, which is equivalent to that the human bones are on a plane, which is helpful for orthopedic surgeons to observe and judge the position and angle of the bones. Like the posterior spine surgery to be done today, the patient is in a prone position on the plaster bed, and the spine is supported by the plaster bed, which can better expose the surgical field.

The nurse in the operating room helps the doctor adjust the patient's position and fix the patient. Anesthesia is also done.

Dr. Liu brought Xie in, and like other surgical operations, preoperative disinfection and laying of sheets were done.

Assisted Dr. Liu in the preoperative preparations, Xie Wanying found out that Geng did not appear. It may be that Geng Yongzhe couldn't bear to see his younger brother lying on the operating table, or that Geng's mother was crying outside and needed comfort from his eldest son, so it was too late.

Orthopedic surgery is said to be more special than other surgical operations, involving bones. The first image that reminds people is that a doctor is like a butcher who chops bones with a knife in a slaughterhouse.

What is not wrong here is that orthopedic surgeons really need to deal with human bones during surgery, and they need to use a knife to work on the bones. The knives that can cut bones must be like knives in the kitchen. If only ordinary knives cannot cut bones, special knives are required. This kind of knife is called ultrasonic bone knife in orthopedics.

What does the ultrasonic bone knife look like? Is it as big as a bone cutter? No, the ultrasonic bone knife is similar to the ordinary electric knife, with a pen shape, except that the blade surface of the knife head is larger than that of the electric knife. Don't underestimate the appearance of this scalpel. It is a small knife. The principle of the ultrasonic bone knife uses high-frequency ultrasonic oscillation, and the force of destroying bones is absolutely comparable to the bone cutting knife.

Not only that, the ultrasonic osteotome can adjust the working frequency. Under a certain frequency limit, it can simply perform mechanical damage on the bone with high acoustic impedance and calcified and mineralized hard tissue, and at the same time automatically screen out the soft tissue with low acoustic impedance to avoid Injury to soft tissue concentrates only on bone lesions. In spine surgery, anatomically, the bones and nerves are closely related and always go together, which requires the doctor to pay special attention during the operation. Ultrasound osteotome can not cut soft tissue orthopedic surgeons can avoid accidental injury to nerves and prevent postoperative sequelae. Therefore, ultrasonic osteotome is a good baby.

The nurse's instrument table has a row of ultrasonic bone cutter heads, and the doctor can choose and switch the cutter heads. In addition to the ultrasonic osteotome, other conventional scalpels and electrosurgical knives are necessary. The assistant lays out the surgical drape.

The main surgeon enters the operating room after brushing his hand.

"Doctor Zhang, I trouble you today." Chang Jiawei put on the surgical gown with the assistance of the nurse and said to the anesthesiologist.
