[0001] The utility model relates to a fracture external fixator, in particular to a humerus, ulna and radius fracture external fixator, belonging to the technical field of medical equipment. Background Art

[0002] At present, closed fixation of fractures in hospitals generally uses plaster fixation. This reduction and fixation method may cause partial displacement of the fracture site again. After the swelling of the fracture site subsides, the fixation device is easy to loosen and needs to be re-fixed, which is troublesome. A few hospitals use fracture external fixators instead of plaster, but there are still some problems in use.

[0003] The utility model patent with publication number CN 206534749 U in the prior art proposes a Mongolian medicine bonesetting external fixator for ulna and radius fractures, which includes a dorsal fixation splint, a palmar fixation splint, a radial / ulnar fixation splint and a fixation belt... It reduces medical expenses and costs, reduces the physiological and psychological burden on patients, and is more practical, but it does not have a good antibacterial effect. The wooden fixation splint is prone to paint peeling, corrosion, decay and other problems after long-term use, and is easy to breed bacteria and other substances harmful to patients, requiring frequent maintenance. In addition, the wooden splint has poor air permeability, poor elasticity and heavy weight, which greatly affects the wearing comfort of patients. The wooden splint is connected and fixed with the fixation belt, which is not convenient for quick replacement and disassembly. At the same time, it does not have the ability to protect the patient's wrist and tiger's mouth, and has a single functionality. Therefore, we need to upgrade and transform it based on the existing technology. Utility Model Content
