[0002] Scoliosis refers to a spinal deformity in which one or more segments of the spine bend laterally, accompanied by vertebral rotation and increased or decreased kyphosis or lordosis in the sagittal plane. It is a three-dimensional deformity.

[0003] When the spine has single or multiple lateral curvatures, it may not only affect the spine, thorax, ribs, and pelvis, but in severe cases, affect the cardiopulmonary function and even affect the spinal cord, causing paraplegia. Mild scoliosis can be prevented or slowed down by guided physical exercise, traction therapy, and especially brace therapy; severe scoliosis requires surgical correction, and patients with scoliosis who require corrective surgery should undergo traction therapy for a period of time before surgery. Traction therapy can improve the vital capacity of scoliosis patients and increase spinal flexibility to improve the efficacy and success rate of scoliosis corrective surgery.

DETAILED DESCRIPTION

[0030] The following is a combination of the appended examples of the present invention Figure 1-11 , the technical solutions in the embodiments of the present utility model are described in detail. Example 1

[0031] like Figure 1 and 2 As shown, a scoliosis head ring traction wheelchair includes a wheelchair 1, a traction component 2 and a support component 3. The support component 3 is detachably mounted on the wheelchair 1. The traction component 2 for traction of the patient is mounted on the support component 3. The traction component 2 can be used to adjust the traction force on the patient.

[0032] The wheelchair 1 is an existing device. The main function of the wheelchair 1 is to serve as a carrier for installing the support component 3 and the traction component 2. The wheelchair 1 can be an existing common ordinary wheelchair.

[0033] like Figure 2 、 3As shown in Figures 4, 7, 8 and 9, the support assembly 3 includes a fixed rod 301, a support vertical rod 302 and a support cross rod 303. The main function of the support assembly 3 is to serve as a carrier for the traction assembly 2, so that the traction assembly 2 can pull the patient sitting in the wheelchair through the support assembly 3. The fixed rod 301 is installed on the backrest of the wheelchair 1, the support vertical rod 302 is set on the fixed rod 301, and the support cross rod 303 is hinged to one end of the support vertical rod 302.

[0034] The fixing rod 301 is a hollow rod with a rectangular cross section. The function of the fixing rod 301 is to connect the supporting vertical rod 302 and the wheelchair 1 and fix the supporting vertical rod 302 on the wheelchair 1. In order to reduce the overall weight, the fixing rod 301 can be made of hard aluminum alloy.

[0035] In order to facilitate the connection between the fixing rod 301 and the wheelchair 1, circular through holes are opened at both ends of the fixing rod 301 and perpendicular to the surface of the fixing rod 301. The fixing rod 301 can be fixed to the fixing clip 304 installed on the backrest of the wheelchair 1 through the circular through holes.

[0036] The fixing clip 304 is composed of two arc-shaped sub-fixing clips, each with mounting holes at both ends. The two arc-shaped sub-fixing clips can be assembled and fixed together using screws and the mounting holes. There is a circular space in the middle of the two assembled arc-shaped sub-fixing clips. The size of this space is slightly smaller than the diameter of the side frame of the wheelchair 1 backrest. The assembled sub-fixing clips can be clamped on the side frame of the wheelchair 1 backrest.

[0037] In order to facilitate the connection between the fixing rod 301 and the fixing card 304, a fixing plate 305 with a rectangular cross-section protrudes perpendicularly to the end surface at one end of the sub-fixing card inside the fixing card 304. A mounting hole penetrating the fixing plate 305 is opened on the surface of the fixing plate 305 perpendicular to the fixing plate 305. This mounting hole corresponds to the mounting hole position at the end of the fixing rod 301. The fixing rod 301 is fixed to the fixing plate 305 by screws, and is then stably fixed to the wheelchair 1.

[0038] Definition: In this embodiment, with the wheelchair as a reference, the direction from the wheelchair pointing to the ground is downward, the direction opposite to it is upward, the direction from the outside pointing to the wheelchair is inward, and the direction from the wheelchair pointing to the outside is outward.

[0039] In order to improve the stability of the support vertical rod 302 fixed on the wheelchair 1, two fixing rods 301 are installed on the backrest of the wheelchair 1, and the two fixing rods 301 are distributed in the upper and lower parts of the backrest of the wheelchair 1 at intervals.

[0040] In order to facilitate the connection between the supporting vertical rod 302 and the fixing rod 301, a group of mounting holes are opened in the middle of the fixing rod 301, perpendicular to the fixing rod 301. The mounting holes pass through the surface of the fixing rod 301. The supporting vertical rod 302 can be installed on the fixing rod 301 through screws and the mounting holes.

[0041] The supporting vertical rod 302 includes an outer rod 306 and an inner rod 307. The lower portion of the outer rod 306 is fixed to the fixed rod 301. The inner rod 307 is inserted into the outer rod 306. The insertion depth of the inner rod 307 in the outer rod 306 is adjustable.

[0042] The function of the supporting vertical rod 302 is to support the traction assembly 2 in the height direction to facilitate traction of the patient. The outer rod 306 and the inner rod 307 are both hollow metal rods with a rectangular cross-section. In order to reduce the overall weight, the outer rod 306 and the inner rod 307 can be made of hard aluminum alloy as a whole.

[0043] Two groups of mounting holes are provided at the lower portion of the outer rod 306 perpendicular to the surface of the outer rod 306 . The two groups of mounting holes correspond to the two fixing rods 301 respectively. The outer rod 306 is fixed to the fixing rods 301 through screws and the mounting holes.

[0044] In order to facilitate the adjustment of the depth of the inner rod 307 inserted into the outer rod 306, a plurality of height adjustment holes 308 are provided on the side of the outer rod 306 perpendicular to the outer rod 306, and the plurality of height adjustment holes 308 are distributed at intervals along the height of the outer rod 306. A circular through hole is provided on the side of the lower end of the inner rod 307 perpendicular to the inner rod 307 and passes through the inner rod 307. The diameter of the circular through hole is the same as the diameter of the height adjustment hole 308. When one of the height adjustment holes 308 on the outer rod 306 is opened When the circular through hole 8 corresponds to the circular through hole on the inner rod 307, an adjusting screw 311 is inserted from the outside through the outer rod 306 and the inner rod 307, which can pin the outer rod 306 and the inner rod 307 together, so that the positions of the outer rod 306 and the inner rod 307 are fixed and no relative movement occurs between the two. In addition, in order to ensure the stability of the fixing of the adjusting screw, a nut is welded at the height adjustment hole 308 on one side of the outer rod 306, and this nut can cooperate with the adjusting screw 311 to prevent the adjusting screw from falling off.

[0045] Regarding the adjustment of the depth of the inner rod 307 in the outer rod 306, when adjusting, first hold the inner rod 307 with your hand, then unscrew the adjusting screw 311, and pull the adjusting screw 311 out of the height adjustment hole 308, then insert the inner rod 307 into the outer rod 306 as needed or pull the inner rod 307 out to the appropriate size, then reinsert the adjusting screw 311 into the height adjustment hole 308, and pass it through the mounting hole on the inner rod 307, and out from the other side of the outer rod 306, and screw the adjusting screw 311 to the nut here to complete the adjustment of the depth of the inner rod 307 in the outer rod 306.

[0046] In order to facilitate the installation of the supporting cross bar 303, a hinge seat 314 is fixed on the side surface of the upper end of the inner rod 307, perpendicular to the inner rod 307. The cross section of the hinge seat 314 is "U"-shaped. The hinge seat 314 is fixed to the upper end of the inner rod 307 by screws, and the supporting cross bar 303 is connected to the inner rod 307 through the hinge seat 314.

[0047] The function of the support cross bar 303 is similar to that of the support vertical bar 302. The function of the support cross bar 303 is to support the traction assembly 2 in the horizontal direction to facilitate traction of the patient. The support cross bar 303 includes an outer cross bar 316 and an inner cross bar 317. The inner cross bar 317 can be adjusted and inserted into the outer cross bar 316. The outer cross bar 316 and the inner cross bar 317 are both hollow metal rods with a rectangular cross section. The dimensions of the outer cross bar 316 and the inner cross bar 317 are slightly smaller than those of the outer rod 306 and the inner rod 307. In order to reduce the overall weight, the outer cross bar 316 and the inner cross bar 317 can be made of hard aluminum alloy as a whole.

[0048] In order to facilitate the adjustment of the depth of the inner cross bar 317 inserted into the outer cross bar 316, a plurality of circular through holes are provided on the side of the outer cross bar 316, perpendicular to the outer cross bar 316, and the plurality of circular through holes are spaced apart along the length direction of the outer cross bar 316. At the same time, a circular through hole is provided on the side of the lower end of the inner cross bar 317, perpendicular to the inner cross bar 317, and passing through the inner cross bar 317. The diameter of this circular through hole is the same as the diameter of the circular through hole on the outer cross bar 316. The outer cross bar 316 and the inner cross bar 317 are pinned together by an adjusting screw 311. In addition, in order to ensure the stability of the fixing of the adjusting screw, a nut is welded at the circular through hole on one side of the outer cross bar 316. This nut can cooperate with the adjusting screw 311 to prevent the adjusting screw from falling off.

[0049] In order to facilitate the hinge connection between the support cross bar 303 and the support vertical bar 302, a hinge platform 315 is welded at the end of the outer cross bar 316. The hinge platform 315 can be hingedly matched with the hinge seat 314, so that the support cross bar 303 can rotate relative to the support vertical bar 302 along the hinge.

[0050] In order to limit the rotation of the support cross bar 303 along the hinge, a limit bar 301 is pinned on the side of the upper end of the inner rod 307. The limit bar 301 is a rectangular metal plate. The limit bar 301 can rotate relative to the inner rod 307 along the pin joint. A circular through hole is provided at the other end of the limit bar 301, and the limit bar 301 and the outer cross bar 316 can be interlaced through an adjusting screw 311 to complete the angle limitation of the support cross bar 303. In order to improve the stability of the fixation of the support cross bar 303, the limit bar 301 is set on both sides of the inner rod 307.

[0051] Because the size of the outer cross bar 316 is slightly smaller than that of the inner bar 307, in order to improve the stability of the fixation of the limit bar 301, an annular boss 313 protrudes outward from the circular through hole on the inner side surface of the limit bar 301. After fixation, the end face of the boss 313 on the limit bar 301 can contact the outer side surface of the outer cross bar 316, thereby improving the stability of the fixation.

[0052] like Figure 1 、 3 As shown in , 4, 5, 6 and 11, the traction assembly 2 includes a traction head ring 21, a pulley group 22, a spring tensioner 23 and a pull rope 24. The pulley group 22 is installed on the support assembly 3, and the pull rope 24 connects the traction head ring 21 and the spring tensioner 23. The pull rope 24 is wound around the pulley group 22.

[0053] The main function of the traction head ring 21 is to be connected to the patient's head to facilitate traction of the patient through the pull rope 24. The traction head ring 21 is an existing device and can be used directly.

[0054] The pulley assembly 22 includes a plurality of pulleys 25, which are pinned to a U-shaped pulley mounting frame 26. The pulleys 25 can rotate relative to the pulley mounting frame 26 along the pin connection. The pulley mounting frame 26 is provided with mounting holes, and the pulley mounting frame 26 is mounted on the support assembly 3 with screws through the mounting holes.

[0055] This embodiment preferably uses four pulleys 25, and the four pulleys 25 are fixed on the support assembly 3, wherein a pulley 25 is fixed on the side surface near the hinge of the outer cross bar 316, a pulley 25 is fixed on the end face of the inner cross bar 317, a pulley 25 is fixed at the end of the inner rod 307, and a pulley 25 is also fixed at the upper end of the outer rod 306. The pull rope 24 passes through the pulley 25 on the inner cross bar 317, the pulley 25 on the outer cross bar 316, the pulley 25 on the inner rod 307 and the pulley 25 on the outer rod 306 in sequence.

[0056] The spring tensioner 23 includes a tension spring 27 and a hook 28 arranged inside the spring tensioner 23. The main function of the spring tensioner 23 is to adjust the traction force of the traction head ring 21 on the patient, replacing the traditional traction weight. A scale value representing the magnitude of the force is set on the surface of the spring tensioner 23. Two tension springs 27 with the same spring coefficient are installed inside the spring tensioner 23. One end of the tension spring 27 is fixed on the spring tensioner 23, and the other end is connected to a pull plate. A pull rod is connected to the pull plate. The pull rod passes through the spring tensioner 23 and is connected to the external hook 28. Pulling the hook 28 can drive the pull rod to move, thereby driving the tension spring 27 to be stretched under force.

[0057] There are two hooks 28 on the spring tensioner 23. The hook 28 that is movably connected to the pull rod is a dynamic hook and is fixed to the other end of the spring tensioner 23. The hook 28 that is connected to the pull rope 24 is a fixed hook. By adjusting the position of the dynamic hook, force can be applied to the spring tensioner 23, thereby adjusting the traction force received by the traction head ring 21.

[0058] In order to facilitate the adjustment of the position of the dynamic hook, multiple tension adjustment platforms 309 are fixed on the side of the upper end of the inner rod 307 with screws. The tension adjustment platform 309 is "T"-shaped, and mounting holes are provided on the horizontal plates on both sides of the vertical arm of the tension adjustment platform 309. The tension adjustment platform 309 is installed on the inner rod 307 through the mounting holes. An elliptical functional hanging hole 312 is provided on the vertical arm of the tension adjustment platform 309, and the dynamic hook on the spring tensioner 23 is hung in the functional hanging hole 312.

[0059] A plurality of tension adjustment platforms 309 are installed at intervals on the inner rod 307 . By adjusting the connection between the spring tensioner 23 and the tension adjustment platforms 309 at different positions on the inner rod 307 , the magnitude of the traction force applied to the patient can be adjusted.

[0060] like Figure 1 and 10 As shown, in order to facilitate patients to eat, read, use respiratory training devices, etc. and improve the comfort of patients, a table board assembly 4 can also be installed in the armrest 11 of the wheelchair. The table board assembly 4 can be stored in the armrest cavity of the armrest 11. When in use, the armrest cover 12 hinged on the armrest 11 can be directly opened to remove the table board assembly 4.

[0061] The table board assembly 4 includes a table board 41, a table board mounting frame 42 and a table board clamping ring 43. The table board mounting frame 42 is a metal mounting frame with an "L"-shaped cross section. A hinge joint is welded at the end of the longer horizontal plate of the table board mounting frame 42, which can be hinged to the hinge seat in the armrest cavity through the hinge joint. One end of the table board mounting frame 42 is fixed in the armrest cavity, and the table board 41 is hinged to the table board mounting frame 42.

[0062] On the shorter vertical board, the 90° range formed by the two vertically distributed boards on the table board mounting frame 42 is the folding range of the table board 41. When the table board assembly 4 is stored in the armrest cavity, the table board 41 flips 90° and contacts the narrower board surface of the table board mounting frame 42. When the table board 41 needs to be used, the table board 41 is unfolded and contacts the wider board surface of the table board mounting frame 42.

[0063] In order to facilitate the removal of the table top assembly 4 from the armrest cavity, a rectangular table top pull ring 43 is fixed to the non-hinged end of the table top mounting frame 42. The table top assembly 4 can be removed from the armrest cavity by pulling the table top pull ring 43.

[0064] The usage process of this embodiment:

[0065] When in use, connect the spring tensioner with a scale display to the traction rope 24, and then hang the spring tensioner on the designated tension adjustment platform 309 according to the traction weight prescribed by the doctor. At this time, the spring tensioner 23 accurately displays the patient's traction weight, which is convenient to use and fundamentally solves the potential risks of the traction weight.

[0066] When the patient needs to pause traction, he only needs to loosen the spring tensioner 23. When the patient needs traction again, he only needs to wait until the patient sits down and then clamp the spring tensioner 23 on the corresponding tension adjustment platform 309, which solves the trouble of taking and placing the traction weight in the past.

[0067] When the patient needs to eat, read, use electronic equipment, or use a respiratory trainer, the armrest cover 12 can be opened and the table top 41 can be taken out from the armrest cavity for use, which is convenient for the patient to use and improves the patient's comfort.

[0068] The support assembly 3 and traction assembly 2 in this embodiment can be used not only for the production of new products but also for the modification of old products. When modifying old products, the support assembly 3 can be directly installed on the wheelchair, and then the traction assembly 2 can be installed on the support assembly 3, which reduces the patient's use cost. In addition, after the patient no longer needs traction, the support cross bar 303 can be folded up or the support assembly 3 and traction assembly 2 can be disassembled, and the traction wheelchair can be used as an ordinary wheelchair, which reduces the patient's use cost.

[0069] The above embodiments are only for illustrating the technical idea of ​​the present invention and cannot be used to limit the protection scope of the present invention. Any changes made on the basis of the technical solution in accordance with the technical idea proposed by the present invention shall fall within the protection scope of the present invention.
