Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a fracture external fixation bracket. Background Art

[0002] A fracture external fixator is a new type of external fixator, which is mainly used for various types of fractures of the limbs, especially more serious open fractures. Its main structure is located outside the body and is connected to the external fixator by external fixation screws. It can effectively maintain the stability and position of the fracture site and reduce the risk of fracture dislocation. During the fracture healing process, stress stimulation can simultaneously reduce the distance between the two broken bone fixation points, thereby eliminating stress shielding and promoting fracture healing. Existing fracture external fixators are not equipped with a locking device, which can easily cause the bracket to loosen or shift, thereby causing dislocation of the fracture site, and may even damage surrounding blood vessels and nerves, increasing the risk of complications.
