Abstract
Description
Technical Field
[0001] This application relates to the field of orthopedic traction technology, and more specifically, to an orthopedic traction device. Background Technology
[0002] When performing orthopedic traction on patients, medical professionals often use continuous traction force to reduce and fix fractures or dislocations, immobilize inflamed limbs, correct limb contractures and deformities, and perform functional exercises.
[0003] In the prior art, application number 202022049437.8 discloses an orthopedic auxiliary traction device, including a base plate and a hydraulic cylinder centrally located on one side of the top of the base plate. A load-bearing plate is fixedly welded to the top of the hydraulic cylinder, and a pillow is centrally located on one side of the top of the load-bearing plate. Extension devices are movably connected to both sides of the load-bearing plate away from the pillow via rotating shafts. An adjustment device is fixedly located at the center of the side of the load-bearing plate away from the pillow. A perineal column is centrally located on the top of the load-bearing plate away from the pillow, and a sponge protective pad is adhered to the side of the perineal column facing the pillow. This orthopedic auxiliary traction device is less likely to affect the fracture or dislocation site, avoiding secondary injury to the patient, reducing patient pain, and lowering the workload and burden on medical staff. It is also easy to adjust, allowing medical staff to accurately and easily reduce and fix fractures or dislocations during traction treatment.
[0004] According to existing technology, most traction devices used by patients in the present technology directly apply traction to the patient. However, some patients need to relax their muscles during traction, such as patients undergoing lumbar traction. In order to avoid muscle stiffness and tearing, the patient's muscles need to be relaxed between lumbar traction sessions. Existing muscle relaxation methods usually involve massaging the patient to help relax the muscles. This method needs to be done before traction, which undoubtedly increases the steps in the traction process and reduces the efficiency of the traction operation. Therefore, there is an urgent need to propose an auxiliary traction device that can relax the patient's muscles while the patient is lying on the traction device. Summary of the Invention
[0005] This application aims to at least address one of the technical problems in the prior art where the use of massage to relax the patient's muscles before traction affects the efficiency of traction. To this end, this application proposes an orthopedic auxiliary traction device.

The piston end of the cylinder is connected to one side of the moving plate. A traction sleeve is installed on the upper side of the moving plate.
[0008] According to some embodiments of this application, the second traction assembly includes a leg-releasing plate located on the upper side of one end of a support plate. The center of the leg-releasing plate is connected to the rotating shaft of a gear three penetrating the support plate. The rotating shaft of the gear three is rotatably connected to the support plate. A sliding groove four is symmetrically opened on the lower side of the leg-releasing plate. A movable plate two is slidably connected in the sliding groove four. A cylinder two is installed on the lower side of the leg-releasing plate. The piston end of the cylinder two is connected to one side of the movable plate two. Another traction sleeve is installed on the upper side of the movable plate two.
[0009] According to some embodiments of this application, a gear is fixedly connected to the rotating rod, and a rotating rod is rotatably provided on the lower side of the support plate. One end of the rotating rod is connected to the gear, and the gear meshes with the gear. The other end of the rotating rod is connected to a reciprocating screw, and a connecting rod is threaded onto the reciprocating screw. One end of the connecting rod is connected to one end of the rack, and the rack meshes with the gear.
[0010] According to some embodiments of this application, a sliding groove is provided on the lower side of the support plate, and a sliding strip provided on one side of the rack slides in cooperation with the sliding groove.
[0011] According to some embodiments of this application, a gear four is rotatably provided on the lower side of the leg rest plate. The gear four meshes with a gear five connected to the shaft of a gear three. A double-headed cam is connected to the lower shaft of the gear four. At least two limiting blocks are provided on the lower side of the support plate. A push plate is slidably provided in the limiting blocks. One side of the push plate is located on one side of the double-headed cam. The other side of the push plate passes through a movable plate two and is connected to a pressing block one. A connecting plate is provided on one side of the push plate. The connecting plate is connected to the pressing block two. A spray bottle is installed on one side of the movable plate two. The pressing block one and the pressing block two correspond to the pressing handles of the two spray bottles, respectively.
[0012] According to some embodiments of this application, one end of the support frame is provided with a sliding hole, which extends to one side of the support frame.
[0013] According to some embodiments of this application, the nozzles of the two spray bottles are connected to the two nozzles respectively through the movable plate 2. The two nozzles are provided with multiple spray holes, and the two nozzles are respectively located on both sides of the patient's feet.
[0014] According to some embodiments of this application, an extension plate is provided on the lower side of the push plate, and an elastic element is provided between the extension plate and one of the limiting blocks.
[0015] According to some embodiments of this application, the movable plate 2 has an opening near the middle, and through holes are respectively formed on both sides of the opening.
[0016] 1. The beneficial effects of this application are as follows: After the patient leans against the inclined backrest and places their legs on the leg rest, the rotating rod 1 rotates the mounting plate, causing the backrest to gradually flatten the patient's upper body. At the same time, through the meshing of gear 1 and gear 2, the rotating rod 2 rotates the reciprocating screw. The connecting rod on the reciprocating screw moves the rack 1, causing the rack 1 to mesh with gear 3. As the rack 1 moves back and forth, gear 3 causes the leg rest to sway left and right, thereby causing the patient's legs, which are fixed by the traction sleeve, to sway left and right to relax the muscles. This allows the patient to relax their muscles while being placed on the traction device, reducing traction steps and improving traction efficiency.
[0017] 2. The beneficial effects of this application are as follows: When the patient places their legs on the leg rest board, the patient needs to take off their shoes. At this time, when gear three rotates, it drives gear five to rotate. By using gear five and gear four to mesh, gear four causes the double-headed cam to rotate. The protruding parts at both ends of the double-headed cam intermittently push one side of the push plate, causing the push plate to repeatedly and intermittently press the handle of the spray bottle with the pressing block one and pressing block two, so that the deodorizing agent in the spray bottle is sprayed out, purifying the odor of the patient's feet.

[0048] The following description, with reference to the accompanying drawings, depicts an orthopedic traction device according to an embodiment of this application.
[0049] like Figures 1 to 9As shown, an orthopedic traction device according to an embodiment of this application includes a support frame 1, a support plate 14 is provided on the upper side of the support frame 1, a first traction component 2 is movably installed on one side of the upper end of the support frame 1, the first traction component 2 is used to support the upper body of the patient, a reclining board 4 is installed near the middle of the support plate 14, the reclining board 4 assists the patient to get onto the traction device, the patient's buttocks can sit on the reclining board 4, a second traction component 5 is movably installed on the other end of the upper end of the support frame 1, and the patient's legs are placed on the second traction component 5.
[0050] Among them, such as Figure 4 As shown, the first traction component 2 includes a rotating rod 21 rotatably connected to one end of the support frame 1. One end of the rotating rod 21 is coaxially connected to the output shaft of the reduction motor 29. After the reduction motor 29 is started, it can rotate the rotating rod 21. At the same time, a mounting plate 22 is fixedly connected to the rotating rod 21. A backrest 23 is connected to the upper side of the mounting plate 22. The backrest 23 moves up and down with the forward and reverse rotation of the rotating rod 21 to assist the patient in lying down and getting up.
[0051] like Figure 5 As shown, the second traction assembly 5 includes a leg rest 52 located on the upper side of one end of the support plate 14. The leg rest 52 is used to place the patient's leg. The center of the leg rest 52 is connected to the shaft of the gear 3 51 that passes through the support plate 14. The leg rest 52 is fixed to the upper side of the support plate 14 by the gear 3 51. Since the shaft of the gear 3 51 is rotatably connected to the support plate 14, when the gear 3 51 rotates, the shaft of the gear 3 51 can rotate together with the leg rest 52.
[0052] In addition, a sliding groove 26 is symmetrically provided on the lower side of the backing plate 23. The sliding groove 26 is slidably connected to the moving plate 25. A traction sleeve 3 is installed on the upper side of the moving plate 25. The traction sleeve 3 is used to fix the upper body of the patient and assist in subsequent traction work. During traction, the moving plate 25 slides in the sliding groove 26 to stretch the traction sleeve 3, so that the patient's body is straightened and the traction effect is achieved. In order to enable the moving plate 25 to move automatically, a cylinder 24 is installed on the lower side of the backing plate 23. The piston end of the cylinder 24 is connected to one side of the moving plate 25. The automatic movement of the moving plate 25 is achieved by the cylinder 24.
[0053] Furthermore, a sliding groove 4 59 is symmetrically provided on the lower side of the leg resting plate 52. A movable plate 2 57 is slidably connected in the sliding groove 4 59. Another traction sleeve 3 is installed on the upper side of the movable plate 2 57. The other traction sleeve 3 fixes the patient's leg. When the movable plate 2 57 slides in the sliding groove 4 59, it stretches the other traction sleeve 3, which works in conjunction with the movable plate 1 25 to complete traction. A cylinder 2 58 is installed on the lower side of the leg resting plate 52. The piston end of the cylinder 2 58 is connected to one side of the movable plate 2 57. The cylinder 2 58 realizes the automatic movement of the movable plate 2 57.
[0054] When the first traction component 2 rotates up and down, it causes the second traction component 5 to swing left and right. Through the left and right swing of the second traction component 5, the patient's legs are moved to swing left and right, thereby slightly stretching the patient's waist and relaxing the patient's muscles.
[0055] To achieve the above objectives, a gear 27 is fixedly connected to the rotating rod 21. A rotating rod 28 is rotatably mounted on the lower side of the support plate 14 via a fixing member. One end of the rotating rod 28 is connected to a gear 285. When the rotating rod 21 rotates with the gear 27, the gear 27 meshes with the gear 285, causing the gear 285 to rotate with the rotating rod 28. A reciprocating screw 281 is connected to the other end of the rotating rod 28. A connecting rod 282 is threaded onto the reciprocating screw 281. A screw nut is embedded inside the connecting rod 282. The screw nut slides through a block inside the screw nut and the threaded groove on the reciprocating screw 281, allowing the reciprocating screw 281 to rotate smoothly. When 81 rotates, the connecting rod 282 moves back and forth on the reciprocating screw 281, and at the same time, one end of the connecting rod 282 is connected to one end of the rack 283. When the connecting rod 282 moves with the rack 283, the rack 283 meshes with the gear 3 51. At this time, the gear 3 51 rotates the leg rest plate 52, causing the leg rest plate 52 to swing with the patient's leg, relaxing the patient's muscles. The swinging motion of the leg rest plate 52 is mainly driven by the geared motor 29 driving the rotating rod 21. Therefore, when the leg rest plate 52 swings, the backrest 23 will tilt up and down with the rotation of the rotating rod 21, so that the patient can relax his muscles well before and after traction.
[0056] To avoid causing secondary injury to the patient, it is necessary to limit the swing amplitude of the leg rest 52 to prevent the leg rest 52 from swinging too far and causing muscle strain to the patient. Therefore, the lengths of the reciprocating screw 281 and the rack 283 are set within a reasonable range. At the same time, when the backrest 23 is on the same horizontal line as the reclining board 4 and perpendicular to the reclining board 4, the middle part of the rack 283 is located on one side of the gear 51, and the connecting rod 282 is also located in the middle position of the reciprocating screw 281. Thus, when the connecting rod 282 moves with the rack 283, the gear 51 can swing the leg rest 52 left and right within a reasonable range.
[0057] Furthermore, in order to keep the rack 283 moving horizontally, a groove 15 is provided on the lower side of the support plate 14. A slide bar 284 provided on one side of the rack 283 slides in cooperation with the groove 15, and the movement direction of the rack 283 is restricted by the groove 15.
[0058] It is worth noting that when the patient places their leg on the leg resting plate 52, they need to remove their shoes. Considering that some patients' feet may have an odor, and traction requires a long time, it is necessary to purify the odor to prevent it from spreading. Therefore, a gear four 53 is rotatably provided on the lower side of the leg resting plate 52, and a notch is opened on one side of the support plate 14, so that the gear four 53 can be directly connected to the leg resting plate 52. At the same time, the gear four 53 meshes with the gear five 56 connected to the shaft of the gear three 51. Furthermore, a double-headed cam 54 is connected to the lower shaft of the gear four 53. Therefore, when the gear three 51 rotates with the gear five 56, the meshing of the gear five 56 with the gear four 53 causes the gear four 53 to rotate with the double-headed cam 54. In addition, at least two limiting blocks 16 are provided on the lower side of the support plate 14. A push plate 55 is slidably provided inside the limiting block 16. One side of the push plate 55 is located on one side of the double-headed cam 54. When the double-headed cam 54 rotates, the protruding parts at both ends intermittently push one side of the push plate 55, causing the push plate 55 to move intermittently to one end. At the same time, the other side of the push plate 55 passes through the second movable plate 57 and is connected to the first pressing block 553. A connecting plate 554 is provided on one side of the push plate 55, and the connecting plate 554 is connected to the second pressing block 555. A spray bottle 7 is installed on one side of the second movable plate 57. The first pressing block 553 and the second pressing block 555 correspond to the pressing handles of the two spray bottles 7, respectively. When the push plate 55 is pushed, it drives the first pressing block 553 and the second pressing block 555 to press the pressing handles of the spray bottles 7. The spray bottles 7 are filled with deodorizing agent, and the sprayed deodorizing agent purifies the odor of the patient's feet.
[0059] Furthermore, the nozzles of both spray bottles 7 are connected to two spray heads 71 respectively through the movable plate 2 57. The two spray heads 71 have multiple spray holes and are elongated, which expands the spray area of the deodorizing agent. The two spray heads 71 are located on both sides of the patient's feet, which improves the purification efficiency of the odor.
[0060] Furthermore, a sliding hole 17 is provided at one end of the support frame 1. The length of the sliding hole 17 is extended to a length sufficient for the push plate 55 to move as the leg plate 52 swings. The stability of the push plate 55 is improved by sliding the push plate 55 in connection with the sliding hole 17.
[0061] Furthermore, an extension plate 551 is provided on the lower side of the push plate 55. An elastic element 552 is provided between the extension plate 551 and one of the limiting blocks 16. The elastic element 552 is squeezed when the push plate 55 is pushed by the double-headed cam 54. When the protruding part of the double-headed cam 54 moves away from the elastic element 552, the elastic action of the elastic element 552 causes the push plate 55 to reset, so that the double-headed cam 54 continues to push the push plate 55.
[0062] Since pressing block 1 553 and pressing block 2 555 are located on the outside of moving plate 2 57, in order not to affect the movement of moving plate 2 57, an opening 571 is provided near the middle of moving plate 2 57. The size of opening 571 can meet the movement distance of push plate 55. At the same time, through holes 572 are provided on both sides of opening 571. Pressing block 1 553 and pressing block 2 555 are respectively adapted to the two through holes 572. When moving plate 2 57 moves, pressing block 1 553 and pressing block 2 555 can pass through the through holes 572.
[0063] like Figures 10 to 13 As shown, since patients need to lie on the traction device during traction, disposable antiseptic pads 63 are needed to pad the patient's legs to prevent cross-infection. After each patient's traction is completed, the antiseptic pads 63 need to be replaced to ensure one pad per patient. To improve efficiency, the antiseptic pads 63 should be replaced when the patient leaves the traction device. To solve this problem:
[0064] Two fixed seats 13 are respectively set on both sides of the leg plate 52. The two fixed seats 13 on both sides are equipped with a sterile pad replacement assembly 6. The sterile pad replacement assembly 6 includes a rotating roller 62 placed in one fixed seat 13, with an unused sterile pad 63 wound on the rotating roller 62. A winding roller 61 is placed in the other fixed seat 13, with a used sterile pad 63 wound on the winding roller 61. The sterile pad 63 is laid on the upper side of the leg plate 52. By rotating the winding roller 61, the used sterile pad 63 is wound up, and at the same time, the rotating roller 62 is rotated to release a new sterile pad 63.
[0065] A fixed sleeve 69 is provided at one end of the take-up roller 61. A sliding sleeve 68 is inserted into the fixed sleeve 69. An insertion hole is provided at the end of the sliding sleeve 68 that is connected to the fixed sleeve 69. After the sliding sleeve 68 is inserted into the fixed sleeve 69, the sliding sleeve 68 is fixed in the fixed sleeve 69 by bolts 691. This improves the stability of the sliding sleeve 68 and facilitates the disassembly and replacement of the take-up roller 61.
[0066] The sliding sleeve 68 is equipped with a telescopic rod 67, and sliders 671 are respectively provided on both sides of one end of the telescopic rod 67. The sliding sleeve 68 is provided with strip grooves 681 on both sides. The sliders 671 slide in the strip grooves 681, which not only improves the stability of the sliding of the telescopic rod 67, but also restricts the sliders 671 by using the strip grooves 681, so that the telescopic rod 67 can rotate together with the sliding sleeve 68 and the take-up roller 61 when it rotates.
[0067] One end of the telescopic rod 67 is connected to one end of the multi-section universal joint 66, and the other end of the universal joint 66 is connected to one end of the rotating rod 65. The other end of the rotating rod 65 is connected to the gear 651. When the gear 651 rotates, it can drive the rotating rod 65 to rotate. In turn, the rotating rod 65 drives the universal joint 66, the telescopic rod 67, and the sliding sleeve 68 to rotate together, thereby realizing the rotation and winding of the take-up roller 61. Since the universal joint 66 has a certain torque, it can bend and rotate with the swing of the leg plate 52. At the same time, through the sliding cooperation between the telescopic rod 67 and the sliding sleeve 68, the universal joint 66 can be extended or retracted when it swings with the leg plate 52, ensuring that the swing of the leg plate 52 does not affect the replacement of the sterilization pad 63.
[0068] To rotate gear 651, a rotating screw 211 is connected to the end of rotating rod 21 away from the reduction motor 29. A connecting block 64 is threaded onto the rotating screw 211. A long rod 642 is slidably provided on the lower side of the connecting block 64. An L-shaped rod 18 is provided on one side of the support frame 1. A limiting groove 19 is opened on the lower side of the L-shaped rod 18. The lower end of the long rod 642 slides in the limiting groove 19. The long rod 642 restricts the connecting block 64 to remain horizontal when it moves on the rotating screw 211. A rack 2 643 is connected to the side of the long rod 642 near the upper end. When the rack 2 643 moves with the connecting block 64 to the location of gear 651, it can mesh with gear 651. When the rack 2 643 meshes with gear 651, gear 651 rotates, realizing the replacement of the sterilization pad 63.
[0069] To ensure that the patient does not interfere with the replacement of the isolation pad 63, after the patient's traction is completed, the backrest 23 is tilted upwards to lift the patient's upper body. During the upward tilting of the backrest 23, the connecting block 64 moves the rack 2 643 toward the gear 651. When the backrest 23 tilts to a certain degree and the rack 2 643 is not engaged with the gear 651, the patient is removed from the traction device. After the patient is removed, the backrest 23 continues to tilt upwards, causing the connecting block 64 to move the rack 2 643 continuously, prompting the rack 2 643 to engage with the gear 651, thereby causing the take-up roller 61 to rotate and replace the isolation pad 63.
[0070] To prevent rack 2 643 from engaging with gear 651 when the backrest 23 tilts downwards, thus avoiding repeated replacement of the isolation pad 63, the long rod 642 can be pulled downwards, causing it to move rack 2 643 away from gear 651. At this time, when the rotating rod 1 21 reverses and causes the backrest 23 to tilt downwards, the connecting block 64 moves back with rack 2 643 without engaging with gear 651. An elastic element 3 641 is provided inside the connecting block 64. The lower end of the elastic element 3 641 is connected to the upper end of the long rod 642, which can reset the long rod 642 after it slides downwards, allowing rack 2 643 to continue engaging with gear 651.
[0071] Both sides of rack 2 643 are provided with positioning grooves 644, and both sides of the upper end of L-shaped rod 18 are provided with sliding grooves 181. Positioning blocks 182 slide in sliding grooves 181. Positioning blocks 182 are connected to the inner wall of sliding grooves 181 through elastic element 183. The side of positioning block 182 near rack 2 643 has an arc-shaped structure. Therefore, after the sterile pad 63 is replaced, medical staff can pull rack 2 643 down to stretch elastic element 3 641 on long rod 642. At the same time, the lower end of long rod 642 extends to the limit. On the lower side of the groove 19, the two sides of the rack 2 643 push the two positioning blocks 182 respectively, causing the positioning blocks 182 to press the elastic element 1 183. When the positioning block 182 enters the positioning groove 644, it fixes the rack 2 643 in the L-shaped rod 18. At this time, the rack 2 643 does not mesh with the gear 651. At the same time, as the connecting block 64 moves back, the rack 2 643 slides with the positioning block 182. After the positioning block 182 is disengaged from the positioning groove 644, the elastic element 3 641 causes the rack 2 643 to reset.
[0072] A protective shell 11 is provided on one side of the support frame 1. The protective shell 11 shields the rack 2 643 and the gear 651. At the same time, a through groove 12 is opened on the protective shell 11, and one end of the rack 2 643 can pass through the through groove 12 to facilitate medical staff to pull down the rack 2 643.
[0073] Specifically, the working principle of this orthopedic auxiliary traction device is as follows: After the patient leans against the inclined backrest 23 and places his / her legs on the leg rest plate 52, the geared motor 29 drives the rotating rod 21 to rotate in the opposite direction, causing the rotating rod 21 to rotate the mounting plate 22, so that the backrest 23 gradually flattens the patient's upper body. At the same time, through the meshing of gear 27 and gear 285, the rotating rod 28 drives the reciprocating screw 281 to rotate. The connecting rod 282 on the reciprocating screw 281 drives the rack 283 to move, so that the rack 283 meshes with the gear 3 51. As the rack 283 moves back and forth, the gear 3 51 drives the leg rest plate 52 to swing left and right, thereby causing the patient's legs, which are fixed by the traction sleeve 3, to swing left and right to relax the muscles.
[0074] At the same time, when gear 3 51 rotates, it drives gear 5 56 to rotate. By using the meshing of gear 5 56 and gear 4 53, gear 4 53 causes double-headed cam 54 to rotate. The protruding parts at both ends of double-headed cam 54 intermittently push one side of push plate 55, causing push plate 55 to press the handle of spray bottle 7 intermittently multiple times with pressing block 1 553 and pressing block 2 555, so that the deodorizing agent in spray bottle 7 is sprayed out to purify the odor of the patient's feet.
[0075] After the patient's traction is completed, the rotating rod 21 rotates forward, causing the support plate 23 to tilt upward, lifting the patient's upper body. While the support plate 23 tilts upward, the leg rest 52 continues to swing left and right to relax the patient's muscles after traction, preventing discomfort from maintaining one position for too long. Simultaneously, the spray bottle 7 sprays deodorizing agent to improve purification efficiency. As the rotating rod 21 rotates, it also rotates the rotating screw 211, causing the connecting block 64 to move the rack 2 643 towards the gear 651. When the support plate 23 tilts to a certain degree, the patient can leave the traction device. At this point, the rack 2 643 is not engaged with the gear 651. As the support plate 23 continues to tilt upward, the rack 2 643... 643 meshes with gear 651, causing gear 651 to rotate with rotating rod 65, which in turn causes universal joint 66, telescopic rod 67 and sliding sleeve 68 to rotate together. Sliding sleeve 68 rotates winding roller 61, causing rotating roller 62 to release new antibacterial pad 63 for replacement. After replacement, rack 2 643 is pulled down, causing positioning block 182 to enter positioning groove 644, and rack 2 643 to move away from gear 651. When the next patient leans against backrest 23, backrest 23 tilts downward, allowing the patient to lie flat. At this time, connecting block 64 moves rack 2 643 back. When positioning block 182 disengages from positioning groove 644, elastic element 3 641 causes rack 2 643 to reset.
