[0001] The invention relates to the technical field of medical devices, in particular to a movable reduction bracket for clinical orthopedics. Background Art

[0002] Orthopedic patients often need to use a reduction brace during rehabilitation, which can promote reduction. Orthopedic soft fixation braces are the most advanced treatment and auxiliary treatment methods in the world today, and are an important part of the world's advanced medical level. Compared with traditional treatment methods, orthopedic soft fixation braces are easy to use and have better treatment effects. They help patients resume exercise and return to work earlier. They have the conformity and stability of plaster fixation, and can also avoid muscle atrophy caused by plaster and other polymer materials.

[0003] After searching, the invention patent with publication number CN110063830B discloses an orthopedic clinical application movable reduction bracket, wherein a fan-shaped groove is arranged on the cylindrical rod, and a fan-shaped block which cooperates with the fan-shaped groove for limiting is arranged on the cylindrical member, and the angle of the fan-shaped block is smaller than the angle of the fan-shaped groove, so that after the fixing ring is fixed to the leg, the fan-shaped groove cooperates with the fan-shaped block to provide a small overall activity space for the patient when performing activities, which can effectively prevent secondary injury to the patient caused by the rigid connection.
