Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, and more specifically, to a lower limb fracture fixing bracket. Background Art

[0002] A fracture refers to a complete or partial break in the continuity of the bone structure. Reduction, fixation, and healing are the three steps in fracture treatment, and fixation is the connecting link between reduction and healing. Good fixation not only consolidates the reduction effect, but also promotes the speed and quality of healing. The fracture treatment fixation positioning bracket can brake, relieve pain, reduce the pain of the injured, prevent the injury from worsening, prevent shock, protect the wound, and prevent infection.
