Description

Technical Field

[0001] The present invention relates to the technical field of spinal correction instruments, and in particular to a multi-dimensional spinal imbalance corrector. Background Art

[0002] The dimensions of spinal imbalance mainly include sagittal imbalance and scoliosis. Sagittal imbalance is manifested as the loss of lumbar lordosis and the increase of thoracic kyphosis angle. Among them, sagittal imbalance caused by the loss of lumbar lordosis is a common spinal deformity. In order to maintain a horizontal line of sight, patients usually activate the compensatory mechanism, which will cause low back pain and limited motor function.

[0003] Existing spinal braces focus on single-dimensional correction of sagittal spinal imbalance or scoliosis, but are unable to address multi-dimensional spinal imbalances and provide targeted correction. Summary of the Invention

[0004] In order to overcome the above-mentioned deficiencies of the prior art, the present invention provides a multi-dimensional spinal imbalance corrector, which can correct multi-dimensional spinal imbalance.

[0005] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0006] A multi-dimensional spinal imbalance corrector, characterized by comprising:

[0007] An upper connecting frame and a lower connecting frame are placed on the back side, the upper connecting frame is provided with a first connecting sleeve, and the first connecting sleeve is used to connect to the torso corresponding to the thoracic section; the lower connecting frame is placed below the upper connecting frame, and a lumbar support is provided at the front end of the lower connecting frame, and the lumbar support supports the back waist at the front end; a second connecting sleeve is provided on the lower connecting frame corresponding to the lower side of the lumbar support, and the second connecting sleeve is connected to the waist or below the waist;

[0008] The power-assist connecting piece is connected between the upper connecting frame and the lower connecting frame. The power-assist connecting piece is connected to the lower connecting frame through a universal joint. A group of elastic pulling pieces arranged symmetrically on the left and right are connected to the power-assist connecting piece. The elastic pulling pieces pull the power-assist connecting piece obliquely downward toward the side and rear.

[0009] The power-assisting connecting piece is connected to the lower connecting frame through a universal joint to ensure that the power-assisting connecting piece can adapt to the lateral rotation and lateral bending movements of the spine.

[0010] Furthermore, in the multi-dimensional spinal imbalance corrector of the present application, the elastic pulling member includes a cable and an elastic member connected in series with the cable.

[0011] Furthermore, a multi-dimensional spinal imbalance corrector in the present application also includes a tension regulator, the tension regulator including a pulley and an adjustment handle, the pulley and the adjustment handle being connected by a transmission; the pulley corresponds one-to-one with the cable, and the cable is connected to the pulley; the tension regulator also includes a locking mechanism, which is used to lock the pulley to prevent the tension on the cable from driving the pulley to rotate. As a preferred embodiment of the present application, in the present application, the adjustment handle is used to drive the pulley to rotate, and the adjustment handle drives the pulley to rotate to retract and release the cable, thereby realizing the adjustment of the tension of the power-assisting connecting member by the elastic pulling member, and the locking mechanism locks the pulley after the size adjustment is completed.

[0012] Furthermore, in a multi-dimensional spinal imbalance corrector disclosed herein, the locking mechanism comprises a worm gear and a worm screw that mesh with each other, the spool being in transmission connection with the worm gear, and the worm screw being in transmission connection with the adjustment handle. As a preferred embodiment of the present invention, the power transmission for driving the spool is sequentially: the adjustment handle, the worm screw, the worm gear, and the spool. The worm screw always locks the worm gear, creating a self-locking effect, eliminating the need for a separate locking operation and improving operational convenience.

[0013] Furthermore, in the multi-dimensional spinal imbalance corrector of the present application, the number of the wire wheels is 2, a pair of wire wheels are coaxially arranged, and the adjustment handle is transmission-connected to the rotating shaft where the pair of wire wheels are located.

[0014] Furthermore, in the multi-dimensional spinal imbalance corrector disclosed herein, the tension adjuster is mounted on the rear side of the lower connecting frame corresponding to the lumbar support, and the second connecting sleeve is connected below the waist. As a preferred embodiment of the present invention, the pulley, adjustment handle, and locking mechanism are all mounted on the lower connecting frame. This offers the advantage of greater integration compared to a tension adjuster independently mounted on the lower connecting frame. Furthermore, the reaction force of the cable and the second connecting sleeve on the lower connecting frame can generate a forward thrust on the lumbar support.

[0015] Furthermore, in the multi-dimensional spinal imbalance corrector of the present application, the second connecting sleeve is connected to the hip. As a preferred embodiment of the present application, with the location where the front end of the lumbar support contacts the lower back as the fulcrum, the cable acting on the lower connecting frame generates a torque on the second connecting sleeve that pulls the hip backward. Combined with the forward thrust of the lumbar support, this exerts a forward rotation couple on the pelvis, thereby simultaneously correcting excessive pelvic backward rotation caused by sagittal plane imbalance of the spine.

[0016] Furthermore, in a multi-dimensional spinal imbalance corrector disclosed herein, the upper connecting frame comprises an upper plate and a lower plate, the lower plate being rotatably connected to the lower end of the upper plate. The first connecting sleeve comprises a strap that encloses the user's shoulders from the front, with the ends of the strap extending rearward from the upper and lower sides of the shoulders to connect to the upper and lower plates, respectively. As a preferred embodiment of the present invention, the upper and lower plates are rotatably connected to accommodate the pitch and roll motion of the user's torso.

[0017] Furthermore, a multi-dimensional spinal imbalance corrector in the present application also includes rollers rotatably mounted on one end of the power-assisting connector near the upper connecting frame, the rollers are mounted in pairs on both sides of the power-assisting connector, a pair of connecting seats are fixed on the rear side of the upper plate, a sliding cavity is provided on the connecting seat, the sliding cavity extends in the spacing direction of the upper connecting frame and the lower connecting frame, and a pair of rollers are respectively rolled in the sliding cavities on both sides, and the rollers are always separated from the bottom end of the sliding cavity. As a preferred solution of the present application, different from the general method of directly hinge the power-assisting connector to the upper connecting frame, the power-assisting connector contacts the side wall of the sliding cavity through the roller to pull the upper connecting frame. Since the roller is always separated from the bottom end of the sliding cavity, it cannot transmit longitudinal tension to the upper connecting frame, so as to avoid the power-assisting connector transmitting the downward tension of the cable to the upper connecting frame to generate harmful downward compression force on the spine.

[0018] Furthermore, in a multi-dimensional spinal imbalance corrector disclosed herein, the power-assisting connector comprises a first rod hinged to a lower connecting frame and a second rod connected to an upper connecting frame. The second rod is slidably connected to the first rod, and an elastic puller is connected to the first rod. As a preferred embodiment of the present invention, based on the above structure, the power-assisting connector is adjustable in length to accommodate users of different heights.

[0019] It can be seen from the above technical solution that the present invention has the following beneficial effects:

[0020] The present application provides a multi-dimensional spinal imbalance corrector, which applies a posterior-inferior pulling force to the power-assisting connector through an elastic puller. The power-assisting connector applies a posterior pulling force to the thoracic spine at the upper connecting frame, while generating a forward thrust at the lumbar support, forming a force couple to correct the sagittal imbalance of the spine. Since the elastic pullers are symmetrically arranged on the left and right sides and pull the power-assisting connector in the lateral-inferior direction, when the spine tilts, the elastic puller on the opposite side of the tilt direction is stretched, and the elastic puller on one side of the tilt direction is shortened. Therefore, the pulling force of the elastic puller on the opposite side of the tilt direction on the power-assisting connector is greater than the pulling force of the elastic puller on the same side of the tilt direction, and a pulling force is generated on the power-assisting connector in the opposite side of the tilt direction, acting on the upper connecting frame to correct the spinal scoliosis. Therefore, the multi-dimensional spinal imbalance corrector in the present application can achieve the correction of multi-dimensional spinal imbalance. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Combine Figure 1 and Figure 2 A multi-dimensional spinal imbalance corrector is shown, comprising:

[0034] The upper connecting frame 1 and the lower connecting frame 2 are placed on the back. The upper connecting frame 1 is provided with a first connecting sleeve, which is used to connect to the corresponding thoracic position of the torso; the lower connecting frame 2 is placed below the upper connecting frame 1. The front end of the lower connecting frame 2 is provided with a waist support 21, which supports the back waist at the front end. The lower connecting frame 2 is provided with a second connecting sleeve 22 corresponding to the lower side of the waist support 21, and the second connecting sleeve 22 is connected to the waist or below the waist.

[0035] The power-assisting connector 3 is connected between the upper connecting frame 1 and the lower connecting frame 2. The power-assisting connector 3 and the lower connecting frame 2 are connected via a universal joint. A pair of symmetrically arranged elastic pull members 4 are connected to the power-assisting connector 3. The elastic pull members 4 pull the power-assisting connector 3 diagonally downward and toward the side and rear. In this specific embodiment, a pair of elastic pull members 4 are provided.

[0036] The multi-dimensional spinal imbalance corrector of this embodiment applies a posterior-inferior pulling force to the power-assisting connector 3 through the elastic pull member 4. The power-assisting connector 3 applies a posterior pulling force to the thoracic spine at the upper connecting frame 1, while generating a forward thrust at the lumbar support 21, forming a force couple to correct the sagittal plane imbalance of the spine. Because the elastic pull members 4 are arranged symmetrically on both sides and pull the power-assisting connector 3 in the lateral-inferior direction, when the spine tilts, the elastic pull member 4 on the side opposite to the tilt direction is stretched, while the elastic pull member 4 on the side of the tilt direction is shortened. Therefore, the pulling force exerted by the elastic pull member 4 on the side opposite to the tilt direction on the power-assisting connector 3 is greater than the pulling force exerted by the elastic pull member 4 on the same side of the tilt direction, thereby generating a pulling force on the power-assisting connector 3 in the opposite direction of the tilt direction and acting on the upper connecting frame 1 to correct the spinal scoliosis. Therefore, the multi-dimensional spinal imbalance corrector of this embodiment can correct the multi-dimensional spinal imbalance. The power-assisting connecting member 3 is connected to the lower connecting frame 2 via a universal joint to ensure that the power-assisting connecting member 3 can adapt to the lateral rotation and lateral bending of the spine. Specifically, the universal joint is a fisheye bearing.

[0037] Combine Figure 2 As shown, in this embodiment, the elastic pulling member 4 includes a cable 41 and an elastic member 42 connected in series with the cable 41. In this embodiment, the elastic member 42 is a tension spring, and in other embodiments, the elastic member 42 can be an elastic rope.

[0038] Combine Figure 4 and Figure 5 As shown, this embodiment also includes a tension regulator 5, which includes a pair of coaxially connected reels 51 and an adjustment handle 53. The reels 51 and the adjustment handle 53 are connected in a transmission manner, and the adjustment handle 53 is used to drive the reels 51 to rotate. A pair of cables 41 are respectively connected to the pair of reels 51. The tension regulator 5 also includes a locking mechanism, which is used to lock the reels 51 to prevent the tension on the cables 41 from driving the reels 51 to rotate. In this embodiment, the adjustment handle 53 is used to drive the reels 51 to rotate. The adjustment handle 53 drives the reels 51 to rotate to retract and release the cables 41, thereby adjusting the tension of the elastic pulling member 4 on the power-assisting connecting member 3. After the adjustment is completed, the locking mechanism locks the reels 51. In this embodiment, the locking mechanism includes a worm wheel 521 and a worm 522 that mesh with each other. The reels 51 are transmission-connected to the worm wheel 521, and the worm 522 is transmission-connected to the adjustment handle 53. The power that drives the spool 51 is transmitted sequentially through the adjustment handle 53, the worm 522, the worm wheel 521, and the spool 51. The worm 522 always locks the worm wheel 521, creating a self-locking effect, eliminating the need for a separate locking operation and improving operational convenience. In this embodiment, to improve compactness, the worm wheel 521 and the pair of spools 51 are coaxially connected, and the worm 522 is coaxially connected to the adjustment handle 53, which is a knob.

[0039] In this embodiment, the tension regulator 5 is arranged on the rear side of the lower connecting frame 2 corresponding to the lumbar support 21, a pair of pulleys 51 are rotatably installed on both sides of the lower connecting frame 2, and the second connecting sleeve 22 is connected below the waist. That is, the pulley 51, the adjustment handle 53 and the locking mechanism are all installed on the lower connecting frame 2. Compared with the tension regulator 5 being independently arranged on the lower connecting frame 2, it has the advantage of high integration. In addition, the lower connecting frame 2 is subjected to the reaction force of the cable 41 and the second connecting sleeve 22, which can generate a forward thrust on the lumbar support 21. Specifically, the second connecting sleeve 22 is connected to the hip. With the position where the front end of the lumbar support 21 contacts the lower back as the fulcrum, when the cable 41 acts on the lower connecting frame 2, it generates a torque pulling the hip backward on the second connecting sleeve 22. Combined with the forward thrust at the lumbar support 21, a forward rotation couple is applied to the pelvis, which can simultaneously correct excessive pelvic rotation caused by sagittal plane imbalance of the spine.

[0040] Combine Figure 5 As shown, a connecting frame 25 is provided at the bottom of the lower connecting frame 2, and the connecting frame 25 is slidably adjustable and connected to the lower connecting frame 2, and the second connecting sleeve 22 is connected to the connecting frame 25. It can adapt to users of different heights.

[0041] In this embodiment, the upper connecting frame 1 includes an upper plate 13 and a lower plate 14. The lower plate 14 is rotatably connected to the lower end of the upper plate 13. The first connecting sleeve is a strap 111. The strap 111 encloses the user's shoulders from the front. The ends of the strap 111 extend rearward from the upper and lower sides of the shoulders and connect to the upper plate 13 and lower plate 14, respectively. In this embodiment, the upper and lower plates 13 and 14 are rotatably connected to accommodate the pitch and roll motion of the user's torso.

[0042] Combine Figure 3 As shown, this embodiment further includes rollers 311 rotatably mounted on one end of the power-assisting connector 3 near the upper connecting frame 1. The rollers 311 are mounted in pairs on both sides of the power-assisting connector 3. A pair of connecting seats 12 are fixed to the rear side of the upper plate 13. The connecting seats 12 are provided with a sliding cavity 10. The sliding cavity 10 extends in the spacing direction between the upper connecting frame 1 and the lower connecting frame 2. The pair of rollers 311 are respectively rolled in the sliding cavities 10 on both sides. The rollers 311 are always separated from the bottom ends of the sliding cavities 10. Different from the conventional method of directly hinge-connecting the power-assisting connector 3 to the upper connecting frame 1, the power-assisting connector 3 contacts the side walls of the sliding cavity 10 via the rollers 311 to pull the upper connecting frame 1. Since the rollers 311 are always separated from the bottom ends of the sliding cavity 10, they cannot transmit longitudinal tension to the upper connecting frame 1, thereby preventing the power-assisting connector 3 from transmitting the downward tension of the cable 41 to the upper connecting frame 1, thereby generating a downward compression force on the spine that is harmful to the spine. Specifically, the roller 311 is a ball bearing connected to the power-assisting connector 3 by screws, so as to avoid the friction between the first rod 31 and the sliding cavity 10 from causing longitudinal pressure.

[0043] Combine Figure 2As shown, in this embodiment, the power-assist connector 3 comprises a first rod 31 hinged to the lower connecting frame 2 and a second rod 32 connected to the upper connecting frame 1. The second rod 32 is slidably connected to the first rod 31, and the elastic pull member 4 is connected to the first rod 31. Based on this structure, the power-assist connector 3 is adjustable in length to accommodate users of different heights. In this embodiment, the first rod 31 is a tubular body that is sleeved onto the second rod 32. The first and second rods 31, 32 are axially locked by a locking pin.

[0044] Combine Figure 6 As shown, in this embodiment, the power-assisting connector 3 and the lower connecting frame 2 are connected to the rotating joint A; the elastic pulling member 4 pulls the power-assisting connector 3 at position B on the power-assisting connector 3, and position B is on the side of the rotating joint A near the upper connecting frame 1; the lumbar support 21 protrudes from the front end of the lower connecting frame 2 along the x-direction; in the preset correction posture, the positional relationship between the power-assisting connector 3 and the lower connecting frame 2 includes: in the x-direction, position B is located on the rear side of the rotating joint A. In this state, the force of the power-assisting connector 3 acting on the lower connecting frame 2 at the rotating joint A can generate a thrust in the x-direction, so that the front end of the lumbar support 21 applies x-direction pressure to the user's lower back. Specifically, the preset correction posture includes a state in which the back is straight.

[0045] The technical principles of the present invention have been described above in conjunction with specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and are not to be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to conceive of other specific embodiments of the present invention without inventive effort, and such embodiments will fall within the scope of protection of the present invention.
