Description

Technical Field

[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 limbs 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.

[0051] The workflow of the technical solution provided by the present invention is as follows:

[0052] By setting the installation device 3, the slider 31 can be inserted into the inside of the annular rail 4 from the disassembly and assembly slot 5, and then the sliding block 31 can be adjusted to slide on the inner side of the annular rail 4, so that the lateral position of the telescopic device 6 and the positioning device 2 can be flexibly adjusted. During the installation process, the positioning spring 343 will reset and push the push plate 344 to move inward. The inward movement of the push plate 344 will drive the positioning pin 345 to be inserted into the inside of the positioning sleeve 342. The mutual insertion and limiting of the positioning pin 345 and the positioning sleeve 342 can assist in the clamping and fixing of the installation device 3, the positioning device 2 and the telescopic device. 6. Moreover, during use, if disassembly or adjustment is required, the pull-out plate 347 can be pulled to drive the connecting shaft 346 to move outward. The outward movement of the connecting shaft 346 will then push the push plate 344 to drive the positioning pin 345 to disengage from the interior of the positioning sleeve 342. At this time, the positioning pin 345 and the positioning sleeve 342 are separated from each other, and then the slider 31 can be removed from the disassembly and assembly slot 5. The whole is easy to disassemble and assemble flexibly, and then the telescopic device 6, the installation device 3 and the positioning device 2 can be quickly disassembled. The overall design is flexible to disassemble and assemble, so that the device can be used according to specific usage requirements.

[0053] Different numbers of positioning devices 2 and telescopic devices 6 are installed according to the thickness of the limbs of different patients, which further improves the adaptability during the overall use. At the same time, the design of the installation device 3, which is easy to disassemble and assemble, allows the telescopic device 6, the installation device 3 and the positioning device 2 to be flexibly disassembled and assembled according to specific needs during use, which greatly simplifies the patient's operation and further improves the convenience of the device during the overall use.

[0054] By setting the telescopic device 6 and the positioning device 2 to cooperate, after the positions of the telescopic device 6 and the positioning device 2 are installed and adjusted through the installation device 3, further adjustment can be made according to the length of the patient's limbs. At this time, by adjusting the rotation of the 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 the 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 device as a whole 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 to move 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 relative to 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 relative to each other. At this time, the limit plug plate 242 slides and moves 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 twisted to move inwards. The inward movement of the adjusting screw 22 can drive the limiting base plate 241 and the limiting plug plate 242 to move inwards. By adjusting the limiting plug plate 242 and the limiting base plate 241 to move inwards, the limiting plug plate 242 and the limiting base plate 241 can be stably attached 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 inwards, 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, so that the limiting base plate 241 and the limiting plug plate 242 can stably extend and retract, which can make them fit more stably on the patient's limbs. The adjustable design enables the overall device 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 overall adaptability of the device during use.
