[0002] With the rapid development of modern society, the aging of the population is rapidly intensifying. There are more and more elderly patients in clinical practice. A large part of them are caused by fractures caused by accidental falls. Data show that intertrochanteric fractures are one of the common fracture types in the elderly, and the incidence rate ranks first among the three typical osteoporotic fractures. The cost of intertrochanteric fracture surgery is huge, which brings great economic pressure to society and families. With the rapid development of minimally invasive technology in orthopedic surgery, doctors need patients to put themselves in a position suitable for surgery during surgery in order to complete the surgery more scientifically and quickly. Therefore, during minimally invasive intertrochanteric fracture surgery, doctors need to restrain the patient's upper limbs and the patient's ipsilateral affected limbs.

[0003] When placing the patient's upper limbs, in order to ensure that the surgical field is fully exposed during surgery and to have a better viewing angle and incision angle, the patient's arms need to be fixed; however, the traditional restraint method is to wrap the patient's upper limbs with soft cloth and then wrap them around to fix them. This method not only has poor stability, but is also troublesome to install and remove. At the same time, the patient's arms cannot be fine-tuned after being fixed, which may affect anesthesia, blood pressure measurement, and fluid observation, making it less adaptable.
