Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, specifically to an orthopedic repositioning and fixation orthopedic device. Background Technology
[0002] Orthotics are a general term for external devices fitted to the limbs, trunk, and other parts of the human body. Orthotics can prevent or correct deformities of the limbs and trunk. With the development of the times, occupational diseases have emerged. Due to occupational problems, many people will have deformities of the trunk and limbs, and deformities will also occur due to diseases. Therefore, orthopedic orthotics have emerged.
[0003] In existing technologies, orthopedic orthotics can only fix and correct the limbs and trunk to protect the bones by limiting the range of limb movement and preventing bone damage. However, for patients undergoing bone repositioning and rehabilitation after surgery, there is no movement protection. The movement speed of the limbs of patients undergoing bone repositioning and rehabilitation after surgery needs to be controlled. If the limbs move quickly, it means that the limbs are exerting force, which increases the damage to the limb bones. Furthermore, restricting the range of limb movement by using positional limitation can lead to secondary injury to the limbs.
[0004] Therefore, the demand for highly reliable products is urgent. Hence, we propose an orthopedic repositioning and fixation orthopedic device that can prevent excessive force damage to the bones and avoid secondary damage caused by sudden restriction of limb movement. Summary of the Invention

[0031] The inner wall of the belt 7 is movably connected with the rotating shaft 8, the outer wall of the rotating shaft 8 is movably connected with the fixing frame 9, the outer wall of the amplification mechanism 22 is movably connected with the clamping mechanism 23, the clamping mechanism 23 comprises the connecting rod 10, the outer wall of the connecting rod 10 is fixedly connected with the rotating shaft 8, the straight rail 11 is provided with two and is symmetric about the center of the connecting rod 10, the inner wall of the circular ring 14 is provided with notches, the notches are six, and the shape of the notches is the same as that of the plug-in block 12, the side, away from the plug-in block 12, of the centrifugal spring 13 is fixedly connected with the connecting rod 10, and the outer wall of the connecting rod 10 is fixedly connected with the straight rail 11.
[0032] The inner wall of the straight rail 11 is slidably connected with the plug-in block 12, the outer wall of the plug-in block 12 is fixedly connected with the centrifugal spring 13, the side, away from the centrifugal spring 13, of the plug-in block 12 is movably connected with the circular ring 14, the outer wall of the clamping mechanism 23 is movably connected with the friction mechanism 24, the inner wall of the friction mechanism 24 is movably connected with the friction round block 20, and the friction mechanism 24 comprises the threaded rod 15.
[0033] One end of the threaded rod 15, away from the circular ring 14, is movably connected with the vertical strip bin 21, the inner wall friction coefficient of the friction sleeve 19 is larger and larger away from the center line, the outer wall of the threaded rod 15 is fixedly connected with the torque spring, the outer wall of the threaded rod 15 is threadedly connected with the threaded sleeve 16, the top of the threaded sleeve 16 is fixedly connected with the connecting plate 17, and the outer wall of the connecting plate 17 is fixedly connected with the telescopic rod 18.

[0035] In use, first, the fixed leg guard 1 is worn on the thigh of the patient, the movable leg guard 4 is worn on the lower leg of the patient, the vertical strip bin 21 is clamped and fixed to the leg, and the soft pad on the outer wall of the vertical strip bin 21 protects the leg of the patient. When the patient moves, the leg bends, at this time, the movable leg guard 4 rotates around the rotating plate 3 as the center, the fixed leg guard 1 cooperates with the ring plate 2 to fix the rotating position of the rotating plate 3, and since the rotating plate 3 is composed of two semicircles with different areas, the upper semicircle has a large area and the lower semicircle has a small area. When the rotating plate 3 rotates by 90 degrees, the rotating plate 3 contacts the fixed leg guard 1 to limit the maximum rotation angle of the rotating plate 3. The rotating plate 3 drives the rotating wheel 6 to rotate, and the rotating wheel 6 drives the friction block 20 to rotate. When the rotating angle of the rotating plate 3 increases, the convex rod on the outer part of the friction block 20 rubs against the friction sleeve 19.

The rotating shaft 8 drives the connecting rod 10 to rotate. When the patient steps quickly, the rotating speed of the connecting rod 10 is fast. The connecting rod 10 uses centrifugal force to throw out the plug 12, which will stretch the centrifugal spring 13 and be clamped with the circular ring 14. The straight rail 11 limits the movement direction of the plug 12. After the plug 12 is clamped with the circular ring 14, the rotation of the connecting rod 10 will drive the circular ring 14 to rotate. The circular ring 14 drives the threaded rod 15 to rotate, the torque spring assists the threaded rod 15 to reset, the threaded rod 15 moves the threaded sleeve 16 in the direction of the circular ring 14, the threaded sleeve 16 drives the friction sleeve 19 to move by means of the connecting plate 17, the telescopic rod 18 controls the guiding effect, the friction sleeve 19 moves in the direction of the threaded sleeve 16, the contact area between the friction sleeve 19 and the friction block 20 becomes larger and larger, the resistance of the rotating plate 3 becomes larger and larger, avoiding the patient from stepping too fast and causing bone strain, and avoiding the stretching caused by stepping too fast.
