The device has good practicality because the angle is adjusted by the coordinated movement of the worm wheel 18 and the rotating shaft 19.
[0042] The usage process of the fracture traction support device provided by this utility model is as follows:
[0043] First, the traction support device needs to be fixed to the bed board to reduce the inconvenience caused to the patient by fracture. Since both ends of the base 1 are fixed with clamping plates 25, and the internal threads of the clamping plates 25 are connected to a second threaded rod 26, a fourth handle 27 is fixed to the bottom of the second threaded rod 26, a second bearing 28 is fixed to the top of the second threaded rod 26, and a pressure plate 29 is fixed to the outside of the second bearing 28. Two guide posts 30 are fixed to the bottom of the pressure plate 29, and both guide posts 30 are slidably connected to the clamping plate 25. Then, rotating the fourth handle 27 causes the second threaded rod 26 to rotate, which in turn causes the second bearing 28 to move, which in turn causes the pressure plate 29 to move. The pressure plate 29 then causes the two guide posts 30 to slide within the clamping plate 25 for guidance. Through the relative movement between the pressure plate 29 and the clamping plate 25, the traction support device is clamped onto the bed, reducing the inconvenience caused to the patient by fracture when using the traction support device.
[0044] Then, the patient's leg is fixed. Since a placement plate 22 is fixed to one end of the pivot 19, and two fixing straps 23 are fixed to the top of the placement plate 22, and a fixing buckle 24 is provided on the outside of one end of the fixing strap 23; through the setting of the placement plate 22, fixing straps 23 and fixing buckles 24, different sizes can be adjusted to adapt to the size of the patient's leg by the cooperation of the fixing straps 23 and fixing buckles 24, so that the patient is more comfortable when fixing the leg and has a better experience when using traction support;
[0045] When the height of the traction support device needs to be adjusted, the mounting box 4 is fixed to the outside of the lifting seat 2. The transmission rod 5 is rotatably connected inside the mounting box 4. The gear 6 is fixed to the outside of the transmission rod 5. The gear 6 is meshed with the rack 7. The lifting rod 8 is fixed to one side of the rack 7. The lifting rod 8 and the lifting seat 2 are slidably connected. The first handle 9 is fixed to one end of the transmission rod 5. The first limit screw 11 is threaded to one side of the top of the lifting seat 2. The connecting column 10 is fixed to the top of the lifting rod 8. One end of the connecting column 10 is fixed to the rotating seat 3. Then, by holding the first handle 9 and turning it, the first handle 9 drives the transmission rod 5 to rotate. The transmission rod 5 drives the gear 6 to rotate. The gear 6 drives the rack 7. The rack 7 drives the lifting rod 8 to slide inside the lifting seat 2. In this way, the height of the traction support device can be adjusted. The height is adjusted to a suitable position and then limited by the first limit screw 11. This makes the height adjustment convenient and flexible.
[0046] When the traction support device needs to be moved and adjusted, since the base 1 has a first bearing 12 fixed at both ends, and a first threaded screw 13 fixed inside the two first bearings 12, and a second handle 14 fixed at both ends of the first threaded screw 13, and a mating block 15 connected to the external thread of the first threaded screw 13, the mating block 15 is slidably connected to the base 1, and the mating block 15 is fixed to the bottom of the lifting seat 2; then, rotating the second handle 14 drives the first threaded screw 13 to rotate, and the first threaded screw 13 drives the mating block 15 to slide inside the base 1. The movement adjustment is achieved by the sliding of the mating block 15, making the movement quick and stable;
[0047] When the angle of the traction support device needs to be adjusted, a worm gear 16 is rotatably connected inside the rotating seat 3. A third handle 17 is fixed to one end of the worm gear 16, and a worm wheel 18 is meshed with the outside of the worm gear 16. A rotating shaft 19 is fixed inside the worm wheel 18 and is rotatably connected to the rotating seat 3. A limit plate 20 is fixed to one end of the rotating shaft 19, and a second limit screw 21 is threaded inside the limit plate 20. Then, the third handle 17 is rotated, which drives the worm gear 16 to rotate, which drives the worm wheel 18 to rotate, and the worm wheel 18 drives the rotating shaft 19 to rotate. The position is fixed after the angle adjustment through the cooperation of the limit plate 20 and the second limit screw 21. In this way, the angle is adjusted by the coordinated movement of the worm wheel 18 and the rotating shaft 19, making the device more practical.
