Description

Technical Field

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

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

[0003] In the field of orthopedic treatment, the application of orthosis is crucial. At present, there are many problems in the actual application of the existing fixed orthopedic orthosis in the prior art. First of all, the overall structure is relatively simple, which makes it unable to cope with the complex treatment needs of different patients. There are significant differences in the limb lengths and thicknesses of different patients, but the existing orthoses often cannot well adapt to this diversity. Secondly, the existing orthoses have complex structures, which not only increases the difficulty of use but also makes patients feel inconvenient during wearing and operation. The complex structure may cause patients to have difficulty in correctly using the orthosis, affecting the treatment effect. Obviously, the existing orthoses cannot be adjusted according to needs and cannot be personalized adjusted for the limb lengths and diameters of different patients, which 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 prior art has imperfect functions and certain defects and deficiencies, so it needs to be improved. Summary of the Invention

[0004] Aiming at the problem that it is not convenient to flexibly adjust according to the limb conditions of different patients in the prior art, the purpose of the present invention is to provide a reduction and fixation orthopedic orthosis.

Finally, this design provides a personalized treatment plan for patients, meeting the specific needs of different patients.

[0019] By setting the telescopic device to cooperate with the positioning device, it can be adjusted according to the limb lengths of patients. Rotating the adjustable armrest drives the adjustable guide block to rotate, causing the carriage to slide within the frame to adjust the total length. At the same time, the limit base plate and the limit insertion plate in the positioning device can also slide relative to each other to adjust the length. After releasing the adjustable armrest, the limit spring can fix the carriage. This design enables the orthosis to flexibly adapt to patients with different limb lengths, providing more precise treatment for patients. In addition, the length adjustment process is simple and easy to operate, improving the treatment efficiency. Moreover, this adjustable-length design increases the versatility of the orthosis and is applicable to more patients in different situations.

[0020] By setting the telescopic device, after the length adjustment is completed, turning the adjustment screw can move the limit base plate and the limit insertion plate inward to stably fit the outer surface of the patient's limbs for positioning and correction. The sliding of the support rod on the circular plate can promote the stable telescopic movement of the limit base plate and the limit insertion plate, further improving the stability of the fit. This stable-fitting design can better correct the patient and enhance the treatment effect. At the same time, this design can adapt to patients with different limb thicknesses and has better adaptability. In addition, the stable fit can also reduce the discomfort of the patient during use, improve the patient's compliance, and is beneficial to the rehabilitation treatment of the patient.

The end of the connecting shaft 346 passes through the positioning frame 341 and is fixedly connected to a pulling plate 347. Both ends of the pulling plate 347 are arc-shaped. The positioning frame 341 is fixed to the outer side of the connecting block 33, providing support for the internal structure. The positioning spring 343 is connected to the push plate 344 and can push the push plate 344 to insert the positioning pin 345 into the positioning sleeve 342, realizing the clamping and fixing of the connecting block 33 and the annular rail 4. The positioning sleeves 342 are arranged at equal intervals in a ring and are fixed to the outer side of the annular rail 4, cooperating with the positioning pins 345 to ensure the accuracy of the connection and being able to fix the installation device 3. The connecting shaft 346 connects the push plate 344 and the pulling plate 347. By pulling the pulling plate 347, the connecting shaft 346 can be driven to move the push plate 344, and then the positioning pin 345 can be disengaged from the positioning sleeve 342, realizing quick disassembly. This design enables the installation device 3 to be stably fixed during use and can be quickly disassembled and adjusted according to needs, improving the flexibility and convenience of use of the orthosis.

The frame 61 is fixedly connected to the connecting block 33 at the bottom, providing a space for the installation and sliding of the carriage 62. The carriage 62 is slidably connected to the inside of the frame 61, enabling length adjustment. The positioning device 2 is movably installed on the outside of the frame 61 and the carriage 62, facilitating adjustment in coordination with the telescoping. The rail frame 631 in the positioning mechanism 63 is fixed to the upper end of the outside of the frame 61, providing support for the elastic members 633 and the adjusting assembly 634. The limit holes 632 are arranged at equal intervals in a linear pattern on both sides of the carriage 62, and in cooperation with the elastic members 633, the carriage 62 can be snap-fixed at different positions. The ends of the elastic members 633 are inserted into the inside of the limit holes 632, ensuring the stability of the carriage 62 after adjusting the length. The adjusting assembly 634 can control the connection state between the elastic members 633 and the limit holes 632, realizing flexible adjustment and fixation of the length.

[0049] As Figures 1 to 6 and Figure 10As shown, the elastic member 633 includes a limit spring 6331. The limit spring 6331 is fixedly connected to both inner ends of the rail frame 631. An end of the limit spring 6331 is fixedly connected with a movable block 6332. The movable block 6332 is slidably connected to both inner ends of the rail frame 631. An outer side of the movable block 6332 is fixedly connected with a limit plate 6333. An inner end of an outer side of the limit plate 6333 is fixedly connected with a limit rod 6334. An end of the limit rod 6334 is inserted into the limit hole 632. The adjusting assembly 634 includes an adjusting guide plate 6341 and an adjusting guide block 6342. The adjusting guide plate 6341 is fixedly connected to an outer side of the movable block 6332. The adjusting guide block 6342 is rotatably connected to a middle part of an outer side of the rail frame 631. An inner end of the adjusting guide plate 6341 and an outer side of the adjusting guide block 6342 are in fitting connection. A top view shape of the adjusting guide plate 6341 is arranged in an L shape. An overall shape of the adjusting guide block 6342 is arranged in an oval shape. An outer side of the adjusting guide block 6342 is fixedly connected with an adjusting handrail 6343. A top view shape of the adjusting handrail 6343 is arranged in a T shape. An inner end of the adjusting guide plate 6341 is arranged in an arc shape as a whole. The limit spring 6331 is connected to the movable block 6332 to provide elastic force for the movable block 6332. The movable block 6332 slides at both inner ends of the rail frame 631 to drive the limit plate 6333 and the limit rod 6334 to move.

The adjusting guide plate 6341 is fixed to the outer side of the movable block 6332 and is in fitting connection with the adjusting guide block 6342. The adjusting guide block 6342 is rotatably connected to the middle part of the outer side of the rail frame 631. Its oval shape can squeeze the adjusting guide plate 6341 during rotation to prompt it to move outward and drive the limit rod 6334 on the limit plate 6333 to disengage from the limit hole 632, facilitating its quick disassembly and assembly. The adjusting handrail 6343 is convenient for operating the adjusting guide block 6342. The L shape and the arc-shaped inner end design of the adjusting guide plate 6341 cooperate well with the adjusting guide block 6342. This design enables the movement of the movable block 6332 to be controlled by rotating the adjusting guide block 6342, thereby realizing the fixation and unlocking of the sliding frame 62 and facilitating the adjustment of the length of the telescopic device 6.

[0050] As Figures 3 to 7As shown, the positioning device 2 includes a circular plate 21, and the circular plate 21 is fixedly connected to the outer ends of the slide 62 and the frame 61 respectively. The circular plate 21 at the upper end is threadedly connected with an adjusting screw 22, and the circular plate 21 at the lower end is slidably connected with a support rod 23.

The upper circular plate 21 is threadedly connected to the adjusting screw 22, and the limiting base plate 241 can be driven to move by rotating the adjusting screw 22, so that it can clamp the patient's limbs. The lower circular plate 21 is slidably connected to the support rod 23 to provide support for the limiting plug plate 242. A slide groove 243 is provided on the inner side of the limiting base plate 241 in the positioning component 24, and the upper end of the limiting plug plate 242 is inserted into the slide groove 243. The two can cooperate to achieve length adjustment. This design enables the positioning device 2 to be adjusted according to the thickness of the patient's limbs, thereby improving the applicability and fixation effect of the orthosis.

[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] The installation of different numbers of positioning devices 2 and telescopic devices 6 according to the thickness of the limbs of different patients further improves the adaptability performance during its overall use. At the same time, the design of the installation device 3 that facilitates disassembly and assembly enables the device to flexibly disassemble and assemble the telescopic device 6, the installation device 3, and the positioning device 2 according to specific needs during use, greatly simplifying the operation for patients and further improving the convenience during the overall use of the device.

[0054] By setting the telescopic device 6 and the positioning device 2 to cooperate, after installing and adjusting the positions of the telescopic device 6 and the positioning device 2 through the installation device 3, further adjustment can be made according to the limb length of the patient's limbs. At this time, by adjusting the rotation of the adjustment handrail 6343, the rotation of the adjustment handrail 6343 will drive the adjustment guide block 6342 to rotate, and the adjustment guide block 6342 is adjusted from the vertical state to the horizontal state. The adjustment guide block 6342 is overall oval, and it 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 6341 to slide outward. The outward movement of the adjustment guide plate 6341 will push the movable block 6332 inside the rail frame 631 to slide outward. By adjusting the outward sliding displacement of the movable block 6332, the limit rod 6334 on the limit plate 6333 can be made to disengage from the limit hole 632. After the limit plate 6333 pulls out the limit rod 6334 from the inside of the limit hole 632, the sliding frame 62 inside the frame 61 loses its limit, and then the sliding frame 62 can be adjusted to slide inside the frame 61. By adjusting the sliding of the sliding frame 62 inside the frame 61, the overall total length of the device can be adjusted.

[0055] After the length adjustment is completed, just loosen the adjustment handrail 6343. At this time, the reset of the limit spring 6331 can 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 inside of the limit hole 632, thereby clamping and fixing the sliding frame 62 inside the frame 61. During the mutual sliding of the sliding frame 62 and the frame 61, the limit base plate 241 and the limit insertion plate 242 on the circular plate 21 of the positioning component 24 in the positioning device 2 can also slide relative to each other. At this time, the limit insertion plate 242 slides inside the chute 243, and the total length of the limit base plate 241 and the limit insertion plate 242 can be flexibly adjusted. Through the telescopic design of the telescopic device 6, the total lengths of the telescopic device 6 and the positioning device 2 can be flexibly adjusted.

[0056] After the length adjustment is completed, the adjusting screw rod 22 can be adjusted to move inwards by twisting. The inward movement of the adjusting screw rod 22 can drive the limit base plate 241 and the limit insertion plate 242 to move inwards. By adjusting the inward movement of the limit insertion plate 242 and the limit base plate 241, the limit insertion plate 242 and the limit base plate 241 can be stably attached to the outer surface of the patient's limbs, enabling stable positioning and correction. At the same time, the adjusting screw rod 22 adjusts the inward movement of the limit base plate 241 and the limit insertion plate 242, so that the whole can better adapt to patients with different limb thicknesses, and the overall has better adaptability. Moreover, during the use process, during the adjustment of the displacement, the support rod 23 can slide on the circular plate 21 to promote the stable telescopic movement of the limit base plate 241 and the limit insertion plate 242, enabling them to be more stably attached to the patient's limbs. Its adjustable design enables the whole device to flexibly adapt to patients with different limb lengths and thicknesses, enabling it to better adapt to patients with different body types, and further improving the adaptability of the whole device during use.
