Description

Technical Field

[0001] This invention relates to the field of orthopedic orthopedic devices, specifically an orthopedic repositioning and fixation device for use in orthopedics. Background Technology

[0002] Orthoses, also known as corrective devices, are a general term for external devices fitted to the limbs, trunk, and other parts of the human body. Their purpose is to prevent or correct deformities of the limbs and trunk, or to treat bone, joint, and neuromuscular diseases and compensate for their functions. They maintain joint stability and restore weight-bearing or mobility by restricting abnormal movements of the limbs or trunk.

[0003] Existing orthopedic orthotics require rotating connectors to facilitate joint rotation during use. However, the rotation position of existing orthotics is fixed, and the rotation position of the worn orthotics cannot correspond to the joint. When the orthotics rotates, it will put pressure on the joint, which will affect the support of the orthotics to the joint. In addition, existing orthotics are fixed by cloth straps, which cannot stably clamp the limb when fixed, which can easily cause the frame to shift and affect the support effect.

The screw 27 is threaded into the threaded hole 211, which is located inside the sliding block 212. Block 212 is slidably connected inside the sliding frame 25. The lower end of the circular piece 1 is fixedly connected to the arc block 213. Pushing the knob 28 drives the screw 27 to move, so that the screw 27 drives the snap-fit ​​piece 29 to move out of the snap-fit ​​frame 210. Then, rotating the knob 28 drives the screw 27 to rotate, so that the screw 27 pushes the inner wall of the threaded hole 211, thereby pushing the sliding block 212 to slide inside the sliding frame 25, so that the position of the upper fixed rod 31 changes, thereby adjusting the bending position of the orthosis, so that the bending position of the orthosis corresponds to the bending position of the limb joint, thereby enabling the orthosis to accurately support the joint.

[0020] Specifically, the connecting assembly 3 includes two fixed rods 31, which are fixedly connected to the sliding block 212 and the arc block 213 respectively. Two collars 32 are sleeved on the surface of each of the two fixed rods 31. Insertion holes 33 are opened on the outer walls of the four collars 32. Fixing bolts 34 are inserted into the interior of each of the four insertion holes 33. U-shaped blocks 35 are fixedly connected to the outer walls of the four collars 32. Fixing shafts 36 are fixedly connected to the interior of each of the four U-shaped blocks 35. L-shaped plates 37 are rotatably connected to the surface of each of the four fixing shafts 36. The four fixing bolts 34 are inserted into the interior of multiple snap-fit ​​grooves 38. The multiple snap-fit ​​grooves 38 are opened on the surface of the two fixed rods 31. Pushing the collars 32 to move on the fixed rods 31 causes the collars 32 to move the arc frame 41 to a suitable position. Then, the fixing bolts 34 are inserted into the insertion holes 33 and into the snap-fit ​​grooves 38, thereby fixing the position of the collars 32.

The lower ends of the eight clamping blocks 49... All are fixedly connected with snap-fit ​​teeth 410. Each of the eight snap-fit ​​blocks 49 has a slot 411 on its surface. Eight bolts 48 are inserted into the eight slots 411 to snap the arc frame 41 onto the limb. Then, push the insert rod 43 to move, so that the insert rod 43 pushes the arc plate 44 to move. When the arc plate 44 moves, it snaps onto the surface of the limb. Then push the snap-fit ​​block 49 to move down, so that the snap-fit ​​teeth 410 at the lower end of the snap-fit ​​block 49 snap onto the tooth block 45. Then, the bolts 48 are threaded into the screw hole 47 to fix the snap-fit ​​block 49. At the same time, the insert rod 43 is fixed to fix the arc plate 44 onto the surface of the limb, so that the arc frame 41 is stably fixed onto the limb.

[0022] Specifically, a support block 214 is fixedly connected to the outer wall of the rotating ring 23. The support block 214 corresponds to the outer wall of the semi-circular cover 21. The rotating ring 23 is supported by the support block 214, thereby limiting the rotation angle of the rotating rod 23.

[0025] Specifically, multiple arc plates 44 are located inside multiple arc frames 41, with one end of the arc plate 44 extending out of the arc frame 41, and the limb is fixed inside the arc frame 41 by the arc plate 44.

[0026] Specifically, the snap-fit ​​teeth 410 snap-fit ​​with multiple tooth blocks 45, and the multiple tooth blocks 45 are fixedly connected to the upper surface of one end of the insertion rod 43 located outside the arc frame 41, thereby fixing the insertion rod 43 through the snap-fit ​​teeth 410 and tooth blocks 45.

[0027] In use, first, push the collar 32 to move on the fixing rod 31, so that the collar 32 moves the arc frame 41 to the appropriate position. Then, insert the fixing bolt 34 into the insertion hole 33, so that the fixing bolt 34 is inserted into the snap-fit ​​groove 38, thereby fixing the position of the collar 32 and snapping the arc frame 41 onto the limb. Then, push the insertion rod 43 to move, so that the insertion rod 43 pushes the arc plate 44 to move. When the arc plate 44 moves, it snaps onto the surface of the limb. Then, push the snap-fit ​​block 49 down, so that the snap-fit ​​teeth 410 at the lower end of the snap-fit ​​block 49 snap onto the tooth block 45. Then, thread the bolt 48 into the screw hole 47, so that the snap-fit ​​block 49 is subjected to... When the device is fixed, the insertion rod 43 is fixed, which fixes the arc plate 44 on the surface of the limb, and the arc frame 41 is stably fixed on the limb. Then, the knob 28 is pushed to drive the screw 27 to move, so that the screw 27 drives the snap-fit ​​piece 29 to move out of the snap-fit ​​frame 210. Then, the knob 28 is rotated to drive the screw 27 to rotate, so that the screw 27 pushes the inner wall of the threaded hole 211, and then pushes the sliding block 212 to slide inside the sliding frame 25, so that the position of the upper fixing rod 31 changes, thereby adjusting the bending position of the orthosis, so that the bending position of the orthosis corresponds to the bending position of the limb joint, and thus the orthosis accurately supports the joint.
