Description

Technical Field

[0001] The invention relates to the technical field of orthopedic traction frames, in particular to an orthopedic traction frame for orthopedic rehabilitation nursing. Background Art

[0002] An orthopedic traction frame is a device used for medical rehabilitation and orthopedic treatment. It is mainly used to correct body deformities, assist in the treatment of fractures or dislocations, and relieve symptoms of nerve compression by applying traction. In rehabilitation training, it serves as an auxiliary device to help patients perform functional exercises and deformity correction.

[0003] After searching, the Chinese patent application with publication number CN119818258A discloses an orthopedic traction frame for orthopedic rehabilitation and nursing, which includes a seat, an adjustable lower limb orthopedic traction component and an upper limb orthopedic traction component. The adjustable lower limb orthopedic traction component is symmetrically rotatably arranged at the front end of the seat, and the upper limb orthopedic traction component is rotatably arranged at the rear end of the seat, wherein the adjustable lower limb orthopedic traction component includes a thigh support plate, an adaptive adjustment support mechanism and a pulling lower limb traction mechanism; the orthopedic traction frame for orthopedic rehabilitation and nursing can adjust the patient's body position according to their own situation and can independently adjust the traction force, and can simultaneously perform traction therapy for the head and neck and lower limbs, is easy to operate, and has high traction therapy efficiency. However, when this solution is actually used, it still has the following shortcomings: To meet the traction needs of different body parts, the aforementioned orthopedic traction frame utilizes two distinct traction sources. For head traction, counterweights are used to apply tension through a pulley system, requiring medical staff to frequently adjust the number of weights to vary the traction intensity. This cumbersome operation process and the process of adding and removing weights poses safety risks. For lower limb traction, traction is provided by a pump-driven hydraulic or pneumatic device. The pump's operation requires connection to a complex piping system, which is not only time-consuming to install and debug but also prone to leaks and unstable pressure during use. The independent configuration of these two traction sources complicates the overall structure of the equipment, occupies a large space, and increases the difficulty of setting up medical facilities.

[0024] like Figures 1 to 3 As shown, an orthopedic traction frame for orthopedic rehabilitation nursing comprises two brackets 11 and a rectangular back plate 12 fixedly mounted on the top ends of the two brackets 11, two fixing frames 13 are symmetrically fixedly mounted on the bottom surface of the rectangular back plate 12, one end of the fixing frame 13 is provided with a connecting plate 18, the end of the connecting plate 18 is hinged with a support plate 14, a leg support plate 15 is fixedly mounted on the top surface of the support plate 14, a pull plate 16 is provided at the other end of the fixing frame 13, a headrest plate 17 is fixedly mounted on the top surfaces of the two pull plates 16, a pull rod 1 21 is fixedly mounted on the inner wall of the pull plate 16, a pull rod 22 is fixedly mounted on the inner wall of one end of the fixing frame 13 away from the pull plate 16, a cross bar 23 is provided between the pull rod 1 21 and the pull rod 2 22, a connecting mechanism is provided between the cross bar 23 and the pull rod 1 21, the pull rod 2 22, and between the fixing frame 13 and the connecting plate 18, the pull plate 16. The connecting mechanism includes two slots 24 provided at both ends of the fixing frame 13. The ends of the connecting plate 18 and the pull plate 16 are fixedly mounted with plug plates 25 that are slidably connected to the slots 24. Guide slots 26 are provided at both ends of the crossbar 23. The ends of the pull rod 1 21 and the pull rod 22 are fixedly mounted with guide rods 27 that are slidably connected to the guide slots 26. A return spring 28 is fixedly mounted between the end of the guide rod 27 and the inner wall of the guide slot 26. The user can lie on the rectangular backboard 12, with the head on the headrest board 17 and the legs on the leg support boards 15. If the user needs to pull the lower limbs, the upper body can be fixed on the rectangular backboard 12 by straps, and the two legs can be fixed on the two leg support boards 15 respectively. The working principle and connection method of the straps are existing mature technologies and will not be elaborated here, and are not shown in the figures.

[0025] like Figure 2 、 Figure 4 、 Figure 6 As shown, the two cross bars 23 are provided with a rectangular traction drive assembly for driving the pull rod 1 21 and the pull rod 2 22. The rectangular traction drive assembly includes four guide sleeves 31 sleeved on the outer walls of the two cross bars 23. A connecting frame 32 is fixedly installed between the outer walls of two guide sleeves 31 on the same side of the four guide sleeves 31, and a fixing plate 36 is fixedly installed between the outer walls of the other two guide sleeves 31. A connecting box 33 is fixedly installed on the bottom surface of the connecting frame 32. Four inclined pressure plates 34 distributed in an annular array are fixedly installed on the end of the guide sleeve 31. An inclined pressure sleeve 35 adapted to the inclined pressure plate 34 is screwed to the outer wall of the guide sleeve 31. A fixing frame 37 is fixedly installed on the side of a bracket 11. An adjusting screw 38 is rotatably installed on the inner wall of the fixing frame 37. A support plate 39 slidably connected to the inner wall of the fixing frame 37 is fixedly installed on the side of the connecting box 33, and the support plate 39 is screwed to the adjusting screw 38. A pulley structure is provided on the connecting box 33. When the adjusting screw 38 is rotated, the connecting box 33 can be driven to move by the supporting rod, thereby driving the guide sleeve 31 to slide, so that the two guide sleeves 31 at both ends of the fixing plate 36 slide to the outer walls of the two pull rods 22, and the two guide sleeves 31 at both ends of the connecting frame 32 are still located on the outer wall of the cross bar 23. At this time, the staff can fix the four guide sleeves 31 and rotate the inclined pressure sleeve 35. Since the inclined pressure sleeve 35 is screwed to the guide sleeve 31, it can slide horizontally when it rotates, thereby squeezing the four inclined pressure plates 34 through the inner wall of the inclined pressure sleeve 35, so that the four inclined pressure plates 34 are firmly fixed to the outer walls of the cross bar 23 and the pull rod 22, thereby completing the fixation of the guide sleeve 31.

[0026] like Figure 6 、 Figure 7 As shown, the pulley structure includes a guide plate 41 fixedly mounted on the side of the connecting box 33, a fixed pulley 42 is provided on the side of the guide plate 41 close to the side of the connecting box 33, and a movable pulley 43 is slidably mounted on the other side of the guide plate 41, and a guide wheel 44 is provided on the end of the connecting frame 32 away from the connecting box 33. A traction rope 45 is fixedly mounted on the side of the fixed plate 36, and the end of the traction rope 45 passes through the connecting frame 32 and bypasses the guide wheel 44 and is fixedly connected to the movable pulley 43. A winding drum 46 is rotatably mounted on the inner wall of the connecting box 33, and a winding motor 47 with an output end fixedly mounted on the side of the connecting box 33 is fixedly mounted. A pull rope 48 is fixedly mounted on the movable pulley 43, and the end of the pull rope 48 bypasses the fixed pulley 42 and the movable pulley 43 in turn and is fixedly connected to the inner wall of the winding drum 46. The staff can perform traction according to the actual situation of the user. When traction is performed, the winding motor 47 can be turned on to drive the winding disc 46 to rotate. When the winding disc 46 rotates, the pull rope 48 can be pulled. When the pull rope 48 is pulled, the movable pulley 43 can be driven to slide along the guide plate 41 in the direction close to the fixed pulley 42, so that the traction rope 45 can be pulled, so that the fixed plate 36 is driven, and the two guide sleeves 31 at both ends of the fixed plate 36 are fixed to the two pull rods 22 respectively, so that the fixed plate 36 is driven. When the pull rod 22 is pulled back, the two pull rods 22 can be driven to slide, so that the inserting plate 25 slides along the slot 24 and the guide rod 27 slides along the guide slot 26, thereby realizing traction rehabilitation training for the user's lower limbs. When resetting, the winding motor 47 can be reversed, and the pull rod 22 can be pulled back to its original position under the action of the reset spring 28. Under the pulling action of the traction rope 45, the movable pulley 43 can also be reset. Through the coordinated use of the fixed pulley 42 and the movable pulley 43, the driving force required for traction is relatively reduced, saving the cost of the device.

[0027] like Figure 8 、 Figure 9 As shown, a positioning assembly for limiting is provided between the support plate 14 and the connecting plate 18, and the positioning assembly includes a mounting groove 51 provided on the side of the support plate 14, an inner wall of the mounting groove 51 is provided with a shaft rod 52, and a positioning plate 53 is fixedly installed on the end of the shaft rod 52, and a limiting strip 54 is fixedly installed on the outer wall of one end where the shaft rod 52 is connected to the positioning plate 53. Two limiting grooves 55 adapted to the limiting strip 54 are provided on the inner wall of the mounting groove 51, and a limiting spring 56 is provided between the end of the shaft rod 52 and the inner wall of the mounting groove 51. A positioning groove 57 is provided on the side of the connecting plate 18, and the length of the limiting strip 54 is at least less than the length of the shaft rod 52 and the same as the depth of the positioning groove 57. A positioning rod 58 is fixedly installed on the end of the positioning plate 53 away from the shaft rod 52, and an oblique support plate 59 corresponding to the fixed plate 36 is fixedly installed on the side of the positioning plate 53; When it is necessary to perform leg-lifting training on the user's lower limbs, the staff can reverse the oblique pressure sleeves 35 on the two guide sleeves 31 connected to the fixing plate 36 to release the squeezing of the oblique pressure plate 34 on the pull rod 22, and the connection between the guide sleeve 31 and the pull rod 22 can be released. In the initial state, the positioning plate 53 is in a horizontal state, the positioning rod 58 is located in the positioning groove 57, and the support plate 14 is connected to the connecting plate 18 through the positioning plate 53 to perform a traction action. The staff can pull the positioning plate 53 to make the shaft rod 52 slide out of the installation groove 51. When the limit bar 54 slides out of the limit groove 55, the positioning plate 53 can be rotated 90 degrees to a vertical state. At this time, The positioning plate 53 is pushed in the reverse direction to push the shaft 52 into the installation groove 51 again, and the limit bar 54 can enter another limit groove 55, so that the positioning plate 53 can be fixed in the vertical position for use, and the diagonal support plate 59 at the end of the positioning plate 53 can correspond to the fixed plate 36. The winding motor 47 is turned on again to drive the fixed plate 36 to slide along the pull rod 22 through the guide sleeve 31. At this time, the fixed plate 36 corresponds to the diagonal support plate 59, and the diagonal support plate 59 is set at an angle. Therefore, the sliding of the fixed plate 36 can push the diagonal support plate 59, and the support plate 14 and the leg support plate 15 can be driven by the positioning plate 53 to rotate along the connecting plate 18 to achieve lifting training for the user's lower limbs.

[0028] like Figure 3 、 Figure 5As shown, a connecting assembly connecting the two is provided between the fixing frame 13 and the leg support plate 15, and the connecting assembly includes two guide openings 61 opened on the top surface of the support plate 14 and the fixing frame 13, a support rod 62 is fixedly installed on the outer wall of the pull rod 22, and the support rod 62 passes through the two guide openings 61, and the outer wall of the support rod 62 fits with the inner wall of the guide opening 61, and an insertion rod 63 corresponding to the support rod 62 is fixedly installed on the bottom surface of the leg support plate 15, and a pin groove 64 is opened on the support rod 62 and the insertion rod 63, and a pin rod 65 is slidably installed on the inner wall of the pin groove 64, and a pull ring is provided at one end of the pin rod 65 located outside the pin groove 64; The staff can pull the pull ring at the end of the pin rod 65 to move the pin rod 65 out of the pin groove 64, thereby releasing the connection between the insertion rod 63 and the support rod 62. When the pin rod 65 is inserted into the pin groove 64, the insertion rod 63 can be connected to the support rod 62, so that when the pull rod 22 is driven, the leg support plate 15 and the support plate 14 can be driven through the support rod 62 and the insertion rod 63.

[0029] like Figure 10 、 Figure 11 As shown, the connecting end of the fixed frame 13 and the pull plate 16 is provided with a reversing assembly for transmitting the pull plate 16, and the reversing assembly includes two mounting frames 71 fixedly mounted on the two fixed frames 13 at one end away from the connecting plate 18, a transmission gear 72 is rotatably mounted between the opposite side surfaces of the two mounting frames 71, a transmission tooth plate 73 meshing with the transmission gear 72 is fixedly mounted between the opposite side surfaces of the two pull plates 16, a driving tooth plate 74 meshing with the transmission gear 72 is slidably mounted on the bottom end of the mounting frame 71, a transmission plate 75 is fixedly mounted on the end of the driving tooth plate 74, and two elastic telescopic rods 76 corresponding to the fixed plate 36 are symmetrically fixed on the bottom surface of the end of the transmission plate 75 away from the driving tooth plate 74, and the horizontal position of the telescopic end of the elastic telescopic rod 76 is lower than the horizontal position of the top surface of the fixed plate 36; When pulling the user's head, the chin strap can be used to fix the user's lower jaw first, and then the guide sleeve 31 is moved to the end of the cross bar 23 away from the pull rod 22 and the two guide sleeves 31 at both ends of the connecting frame 32 are fixedly connected to the cross bar 23. During the movement of the guide sleeve 31, the fixed plate 36 moves accordingly and shortens the elastic telescopic rod 76 to make way for the fixed plate 36 when passing through the elastic telescopic rod 76, and then the elastic telescopic rod 76 is released; the winding motor 47 can be turned on to drive the fixed plate 36. When the fixed plate 36 moves, it can pull the elastic telescopic rod 76 and drive the drive gear plate 74 to slide. The drive gear plate 74 engages with the transmission gear 72, and then drives the transmission gear 72 to rotate and drive the transmission gear plate 73 and the transmission plate 75, so that the pull plate 16 slides away from the fixed frame 13, thereby achieving traction on the user's head.

[0030] The technical solution provided by the present invention is that when in use, the user can lie on the rectangular backboard 12, with the head on the headrest board 17 and the legs on the leg support boards 15. At this time, the four guide sleeves 31 are located on the two cross bars 23. If the user needs to pull the lower limbs, the upper body can be fixed to the rectangular backboard 12 by the straps, and the two legs are fixed to the two leg support boards 15 respectively. The working principle and connection method of the straps are all existing mature technologies and will not be described in detail here. They are not shown in the figure. Then the staff can rotate the adjusting screw 38, and the support plate 39 is slidably connected to the inner wall of the fixed frame 37 and is screwed to the adjusting screw 38. Therefore, when the adjusting screw 38 is rotated, the support plate 39 can be adjusted by the support plate 38. The rod drives the connecting box 33 to move, thereby driving the guide sleeve 31 to slide, so that the two guide sleeves 31 at both ends of the fixing plate 36 slide to the outer walls of the two pull rods 22, and the two guide sleeves 31 at both ends of the connecting frame 32 are still located on the outer wall of the cross bar 23. At this time, the staff can fix the four guide sleeves 31 and rotate the oblique pressure sleeve 35. Since the oblique pressure sleeve 35 is screwed to the guide sleeve 31, it can slide horizontally when it rotates, thereby squeezing the four oblique pressure plates 34 through the inner wall of the oblique pressure sleeve 35, so that the four oblique pressure plates 34 are firmly fixed to the outer walls of the cross bar 23 and the pull rod 22, thereby completing the fixation of the guide sleeve 31; The staff can perform traction according to the actual situation of the user. When traction is performed, the winding motor 47 can be turned on to drive the winding disc 46 to rotate. When the winding disc 46 rotates, the pull rope 48 can be pulled. When the pull rope 48 is pulled, the movable pulley 43 can be driven to slide along the guide plate 41 in the direction close to the fixed pulley 42, so that the traction rope 45 can be pulled, so that the fixed plate 36 is driven, and the two guide sleeves 31 at both ends of the fixed plate 36 are fixed to the two pull rods 22 respectively, so that the fixed plate 36 is driven. When the pull rod 22 is pulled back, the two pull rods 22 can be driven to slide, so that the inserting plate 25 slides along the slot 24 and the guide rod 27 slides along the guide slot 26, thereby realizing traction rehabilitation training for the user's lower limbs. When resetting, the winding motor 47 can be reversed, and the pull rod 22 can be pulled back under the action of the reset spring 28. Under the pulling action of the traction rope 45, the movable pulley 43 can also be reset. By using the fixed pulley 42 and the movable pulley 43 in conjunction with each other, the driving force required for traction is relatively reduced, saving the cost of the device. If it is necessary to perform leg-lifting training on the user's lower limbs, the staff can reverse the oblique pressure sleeves 35 on the two guide sleeves 31 connected to the fixing plate 36 to release the squeezing of the oblique pressure plate 34 on the pull rod 22, and the connection between the guide sleeve 31 and the pull rod 22 can be released. In the initial state, the positioning plate 53 is in a horizontal state, the positioning rod 58 is located in the positioning groove 57, and the support plate 14 is connected to the connecting plate 18 through the positioning plate 53 to perform traction. The staff can pull the positioning plate 53 to make the shaft rod 52 slide out of the installation groove 51. When the limit bar 54 slides out of the limit groove 55, the positioning plate 53 can be rotated 90 degrees to a vertical state. At this time, the positioning plate 53 is pushed back to push the shaft rod 52 into the installation groove 51 again, and the limit bar 54 can enter the other limit groove 55, so that the positioning plate 53 can be fixed in the vertical position When the support plate 36 is in the state of rotation, the support plate 36 is rotated by the support rod 62 and the support plate 14 is rotated by the support rod 62, thereby achieving the lifting of the user's lower limbs. When the user's head is pulled, the chin strap 31 can be used to fix the user's lower jaw, and then the guide sleeve 31 is moved to the end of the cross bar 23 away from the pull rod 22 and the two guide sleeves 31 at both ends of the connecting frame 32 are fixedly connected to the cross bar 23. During the movement of the guide sleeve 31, the fixing plate 36 moves accordingly and shortens the elastic telescopic rod 76 to make way for the fixing plate 36 when passing through the elastic telescopic rod 76, and then the elastic telescopic rod 76 is released; the winding motor 47 can be turned on to drive the fixing plate 36. When the fixing plate 36 moves, the elastic telescopic rod 76 can be pulled and the driving gear plate 74 can be driven to slide. The driving gear 74 engages with the transmission gear 72, and then the transmission gear 72 can be driven to rotate and drive the transmission gear plate 73 and the transmission plate 75, so that the pulling plate 16 slides away from the fixing frame 13 to achieve traction of the user's head; during the whole traction process, traction and training of different parts of the body can be achieved by adjusting the position of the guide sleeve 31, which makes the operation more convenient and the traction training force control more accurate.
