[0002] With the development and progress of science and technology, orthopedics has made great progress in diagnosis and treatment. Traumatology is a branch of orthopedics, and it is aimed at people with various traumatic orthopedic diseases. For example, upper arm fractures, including humeral fractures, forearm ulna and radius fractures, lower limb fractures, spinal fractures, and fractures in other parts of the body. Trauma diagnosis and treatment techniques have been rapidly popularized and improved, so that some complex fractures can also be treated with internal fixation.

[0003] In orthopedic treatment, the treatment of limb trauma generally requires regular application of medicine to the wound after bone setting, steel plates and wound suturing. After the application of medicine, the wound needs to be wrapped and bandaged with medical cotton wool and medical bandages. When bandaging, the doctor usually manually holds the patient's arms and other parts that need to be bandaged in place, and keeps the injured part in a certain posture or angle for bandaging to ensure that the affected part will not be strained. The method of manually holding the posture to fix the posture has a certain deviation and error rate, resulting in poor bandaging effect and low efficiency of manual bandaging.
