Description

Technical Field

[0001] The present invention relates to the technical field of orthopedic orthoses, and more particularly to a reduction and fixation orthopedic orthosis. Background Art

[0002] Reduction and fixation orthopedic orthosis is a medical device that plays an important role in orthopedic treatment. It is mainly used for reduction and fixation after trauma such as fractures and dislocations, as well as correction of limb deformities caused by various orthopedic diseases. It is usually composed of polymer materials, metal brackets, straps and other components. In terms of reduction, it can apply appropriate external force to the fractured or dislocated parts to help the injured bones return to their normal anatomical position. During the fixation process, it can stably maintain the position of the injured part, limit inappropriate limb movement, create good conditions for bone healing, and relieve the patient's pain. For limb deformities, it can gradually change the morphology of the limb through continuous corrective force, promote the remodeling of bones and soft tissues, thereby achieving the purpose of improving limb function and appearance. It plays an indispensable and important role in orthopedic rehabilitation treatment.

[0003] In the field of orthopedic treatment, the application of orthoses is of vital importance. At present, there are many problems in the actual application of fixed orthopedic orthoses in the existing technology. First, the overall structure is relatively simple, which makes it seem powerless when facing the complex treatment needs of different patients. There are great differences in the length and thickness of the limbs of different patients. However, existing orthoses often cannot adapt well to this diversity. Secondly, the existing correctors have a complex structure, which not only increases the difficulty of use, but also makes patients feel inconvenient during wearing and operation. The complex structure may make it difficult for patients to use the orthosis correctly, affecting the treatment effect. Obviously, the existing orthosis cannot be adjusted according to needs, and cannot be personalized according to the limb length and diameter of different patients. This greatly limits the versatility of the orthosis and cannot meet the specific needs of different patients. It can be seen that the fixed orthopedic orthosis in the existing technology is not perfect in function and has certain defects and deficiencies, so it needs to be improved. Summary of the Invention

At this time, by adjusting the rotation adjustment armrest 6343, the rotation of the adjustment armrest 6343 will drive the adjustment guide block 6342 to rotate, and the adjustment guide block 6342 is adjusted from a vertical state to a horizontal state. The adjustment guide block 6342 is an elliptical shape as a whole, and can squeeze the inner end of the adjustment guide plate 6341 when rotating. The inner end of the adjustment guide plate 6341 is arranged in an arc shape. At this time, the adjustment guide block 6342 can squeeze the adjustment guide plate 6 341 slides toward the outside, and the outward movement of the adjusting guide plate 6341 will push the movable block 6332 inside the rail frame 631 to slide toward the outside. By adjusting the movable block 6332 to slide toward the outside, the movable block 6332 can drive the limiting rod 6334 on the limiting plate 6333 to disengage from the limiting hole 632. After the limiting plate 6333 pulls the limiting rod 6334 out of the limiting hole 632, the slide 62 inside the frame 61 loses its limit, and then the slide 62 can be adjusted to slide on the inside of the frame 61. By adjusting the slide 62 to slide on the inside of the frame 61, the total length of the entire device can be adjusted.

[0055] After the length adjustment is completed, you only need to loosen the adjusting armrest 6343. At this time, the limit spring 6331 is reset to push the movable block 6332 inward. The displacement of the movable block 6332 will drive the limit plate 6333 to push the limit rod 6334 to insert into the inner side of the limit hole 632, and then the slide 62 inside the frame 61 is clamped and fixed. In the process of the slide 62 and the frame 61 sliding with each other, the limit base plate 241 and the limit plug plate 242 on the circular plate 21 of the positioning assembly 24 in the positioning device 2 can also slide with each other. At this time, the limit plug plate 242 slides and displaces inside the slide groove 243, and the total length of the limit base plate 241 and the limit plug plate 242 can be flexibly adjusted. Through the telescopic design of the telescopic device 6, the total length of the telescopic device 6 and the positioning device 2 can be flexibly adjusted.

[0056] After the length adjustment is completed, the adjusting screw 22 can be adjusted and moved inward. The inward movement of the adjusting screw 22 can drive the limiting base plate 241 and the limiting plug plate 242 to move inward. By adjusting the limiting plug plate 242 and the limiting base plate 241 to move inward, the limiting plug plate 242 and the limiting base plate 241 can be stably fitted to the outer surface of the patient's limbs, which can be stably positioned and corrected. At the same time, the adjusting screw 22 adjusts the limiting base plate 241 and the limiting plug plate 242 to move inward, so that the whole can better adapt to different thicknesses. The overall adaptability is better for patients with limbs, and during use, when adjusting the displacement, the support rod 23 can slide on the circular plate 21, prompting the limiting base plate 241 and the limiting plug plate 242 to stably extend and retract, which can make them fit more stably on the patient's limbs. Its adjustable design enables the device as a whole to flexibly adapt to patients with different limb lengths and thicknesses, so that it can better adapt to patients of different body shapes, further improving the adaptability of the device during overall use.
