Technical Field

[0002] A fracture refers to an interruption in the integrity or continuity of a bone, which is usually caused by various violent injuries or bone diseases. Fractures can occur in one location or multiple locations throughout the body. When a fracture occurs in the lower leg, most cases require surgery to reposition the fracture, connect and fix the fractured parts with steel plates or nails, and accelerate the healing of the fracture. Currently, after the surgery, an orthopedic fracture splint is generally used to reposition and fix the patient's lower leg fracture to facilitate the growth and healing of the fractured parts. At present, orthopedic fracture splints are generally fixed manually, using wooden boards or plastic boards to make small splints of appropriate length and width, adding a fixing pad to the fracture site, tying the splint outside the fracture site, and tying a horizontal belt or wrapping a bandage to fix the fracture site. The wrapping range is large, making the manual fixation time-consuming and laborious as a whole, and only having an ordinary fixation effect, without a protective mechanism. When external factors collide with the fracture site of the lower leg, it is easy to cause secondary injuries, which may cause loosening after positioning and fixation, which is not helpful for the recovery effect of the fracture position, resulting in low security of fixation, which not only causes discomfort to patients, but also affects their recovery; Based on this, the present invention provides a fracture dressing splint that is convenient for replacing internal medicines to solve the problems raised in the above-mentioned background technology.
