Abstract
The present invention relates to a shape memory bone fixing splint, which is made from shape memory high molecular materials and electrothermal materials; the shape memory bone fixing splint is similar to a fracture or orthopedic region, but the caliber of the shape memory bone fixing splint is smaller. When heated to a transformation temperature or above the transformation temperature, the shape memory bone fixing splint becomes soft and contracts to tightly cover the fracture or orthopedic region; when cooled below the transformation temperature, the shape memory bone fixing splint becomes hard to perform a fixing function. When the fracture or orthopedic region is found unsatisfactory through radiography, or when the tumefaction region of patients generates regression, or when an affected region generates muscular dystrophy to make the bone fixing splint become loose, the bone fixing splint only needs reheating to be softened and cooling to induration after the fracture or orthopedic region is treated.
Description
Technical field
The present invention relates to the skeletal fixation clamping plate that are used for fracture fixation, also relate to the skeletal fixation clamping plate that are used for skeleton deformity, also relate to and be used for various surgical operation skeletons and need orthopedic again fixed skeletal fixation clamping plate, particularly relate to the skeletal fixation clamping plate that adopt shape-memory material to make.
