The invention relates to the field of medical instruments, in particular to an adjustable noninvasive external fixing device for progressive correction of limb fractures, which comprises two fixing rings, adjusting chutes are formed in the surfaces of the fixing rings along the axial directions of the fixing rings, and connecting rod assemblies are slidably connected in the adjusting chutes. Fulcrum plates are hinged to the ends, far away from the fixing ring, of the connecting rod assemblies, and the ends, far away from the connecting rod assemblies, of the two fulcrum plates are hinged; an elastic assembly used for providing traction force for folding the two fulcrum plates is arranged between the two fulcrum plates. The connecting rod assembly is used for transmitting the traction force generated by the elastic assembly to the fixing ring. Based on a traditional gypsum wedge-shaped correction technology principle, through fixing of the fixing ring, sliding adjustment of the connecting rod assembly and angle adjustment of the fulcrum plate, continuous and stable traction force provided by the elastic assembly is matched, correction stress is accurately transmitted to a limb malformation part, the progressive correction effect is achieved, clinical operation steps are simplified, and the operation efficiency is improved. And the working intensity and the operation difficulty of medical staff are reduced.

This invention provides an external fixation frame for limb fractures, relating to the field of fracture fixation technology. It includes a main fixation component, a secondary fixation component, a length adjustment component, an angle adjustment component, a fixation element, and a movement component. The main fixation component includes a main fixation frame with a main adjustment groove on its long side and main through-channels on both its upper and lower sidewalls. The secondary fixation component includes a secondary fixation frame with a secondary adjustment groove on its long side and secondary through-channels on both its upper and lower sidewalls. The length adjustment component allows for adjustment of the distance between the two fixation positions, making it suitable for fractures of different lengths. Furthermore, the use of a drug-eluting silicone sleeve effectively inhibits early bacterial colonization, significantly reducing the risk of pin tract infection and secondary loosening.

This invention provides a partially detachable orthopedic splint, belonging to the field of medical device technology. It includes a positioning and adjustment structure, and splint fixing structures located at both ends of the positioning and adjustment structure. Auxiliary positioning structures are provided on both sides of the splint fixing structure. By using the splint fixing structure in conjunction with the auxiliary positioning structures, during dressing changes, rotating the telescopic ring causes the two splints to move away from each other through the adjustment frame and support arm. This exposes the wound surface at the splint-covered area of ​​the fracture. Simultaneously, as the two adjustment frames move continuously, the two longitudinal sleeves move closer together, causing the positioning ring frames on both sides to move closer together, fixing the upper and lower sides of the limb fracture site. This ensures that while the wound surface is being cleaned and dressing changed, the ends of the fractured limb still have fixing structures supporting the original fixation position, greatly reducing the problem of secondary bone damage during debridement.
