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. 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 compensatory mechanisms, which will cause low back pain and limited motor function.

[0003] Existing spinal correctors focus on single-dimensional independent correction of sagittal imbalance or scoliosis of the spine, and it is difficult to take into account multi-dimensional imbalance of the spine for targeted correction. Summary of the invention

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

A group of elastic pulling pieces arranged symmetrically on the left and right are connected to the power-assist connecting piece, and the elastic pulling pieces pull the power-assist connecting piece obliquely downward toward the side and rear direction.

[0006] 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.

[0007] 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.

[0008] Furthermore, a multi-dimensional spinal imbalance corrector in the present application also includes a tension regulator, the tension regulator includes a wire wheel and an adjustment handle, the wire wheel and the adjustment handle are connected by transmission; the wire wheel corresponds to the cable one by one, and the cable is connected to the wire wheel; the tension regulator also includes a locking mechanism, the locking mechanism is used to lock the wire wheel to prevent the tension on the cable from driving the wire wheel to rotate. As a preferred embodiment of the present application, in the present application, the adjustment handle is used to drive the wire wheel to rotate, and the adjustment handle drives the wire wheel to rotate to retract and release the cable, so as to achieve the adjustment of the tension of the power-assisting connecting member by the elastic pulling member, and the locking mechanism locks the wire wheel after the size adjustment is completed.

[0009] Furthermore, in the present application, a multi-dimensional spinal imbalance corrector, the locking mechanism includes a worm wheel and a worm screw that mesh with each other, the wire wheel is connected to the worm wheel by transmission, and the worm screw is connected to the adjustment handle by transmission.

[0011] Furthermore, in the present application, a multi-dimensional spinal imbalance corrector, the tension regulator is arranged 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 solution of the present application, the wire wheel, the adjustment handle and the locking mechanism are all installed on the lower connecting frame, which has the advantage of high integration compared to the tension regulator being independently arranged on the lower connecting frame. In addition, the reaction force of the lower connecting frame from the cable and the second connecting sleeve can generate a forward thrust on the lumbar support.

[0012] Furthermore, in the multi-dimensional spinal imbalance corrector of the present application, the second connecting sleeve is connected to the hip. As a preferred solution of the present application, the position where the front end of the lumbar support contacts the back waist is used as a fulcrum, and when the cable acts on the lower connecting frame, a torque is generated on the second connecting sleeve to pull the hip backward, and combined with the forward thrust of the lumbar support, a forward rotation couple is applied to the pelvis, which can simultaneously correct the excessive pelvic backward rotation caused by the imbalance of the sagittal plane of the spine.

As a preferred embodiment 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 rollers to pull the upper connecting frame, and since the rollers are always separated from the bottom end of the sliding cavity, they 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.

[0015] Furthermore, in a multi-dimensional spinal imbalance corrector in the present application, the power-assisting connecting member comprises a first rod body hinged on a lower connecting frame and a second rod body connected to an upper connecting frame, the second rod body is slidably connected to the first rod body, and the elastic traction member is connected to the first rod body. As a preferred embodiment of the present application, based on the above structure, the power-assisting connecting member can be adjusted in length to accommodate users of different heights.

[0016] It can be seen from the above technical solution that the present invention has the following beneficial effects: The present application provides a multi-dimensional spinal imbalance corrector, which applies a pulling force in the posterior-inferior direction to the power-assisting connecting member through an elastic pulling member, and the power-assisting connecting member applies a backward pulling force to the thoracic vertebra at the upper connecting frame, and generates a forward thrust at the lumbar support, forming a force couple to correct the sagittal imbalance of the spine. Since the elastic pulling member is symmetrically arranged on the left and right, and pulls the power-assisting connecting member in the lateral-inferior direction, when the spine tilts, the elastic pulling member on the opposite side of the tilt direction is elongated, and the elastic pulling member on one side of the tilt direction is shortened. Therefore, the pulling force of the elastic pulling member on the opposite side of the tilt direction on the power-assisting connecting member is greater than the pulling force of the elastic pulling member on the same side of the tilt direction, and a pulling force is generated on the power-assisting connecting member in the opposite side of the tilt direction to act on the upper connecting frame to correct the spinal scoliosis. Therefore, a multi-dimensional spinal imbalance corrector in the present application can realize the correction of multi-dimensional spinal imbalance. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] Combination Figure 1 and Figure 2 A multi-dimensional spinal imbalance corrector is shown, comprising: An upper connecting frame 1 and a lower connecting frame 2 are arranged on the back side, the upper connecting frame 1 is provided with a first connecting sleeve, and the first connecting sleeve is used to connect the trunk corresponding to the thoracic section; the lower connecting frame 2 is arranged below the upper connecting frame 1, and a waist support 21 is provided at the front end of the lower connecting frame 2, and the waist support 21 is supported at the back waist at the front end, and a second connecting sleeve 22 is provided on the lower connecting frame 2 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; The power-assisting connecting member 3 is connected between the upper connecting frame 1 and the lower connecting frame 2. The power-assisting connecting member 3 is connected to the lower connecting frame 2 through a universal joint. A group of elastic pulling members 4 arranged symmetrically on the left and right are connected to the power-assisting connecting member 3. The elastic pulling members 4 pull the power-assisting connecting member 3 obliquely downward toward the side and rear direction. In the specific embodiment, a pair of elastic pulling members 4 is provided.

[0020] In the multi-dimensional spinal imbalance corrector of the present embodiment, the elastic traction member 4 applies a pulling force in the posterior-inferior direction to the power-assisting connecting member 3. The power-assisting connecting member 3 applies a pulling force in the posterior-inferior direction to the thoracic vertebra at the upper connecting frame 1, and generates a forward thrust at the lumbar support 21, forming a force couple for correcting the sagittal imbalance of the spine. Since the elastic traction member 4 is arranged symmetrically on the left and right, and pulls the power-assisting connecting member 3 in the lateral-inferior direction, when the spine tilts, the elastic traction member 4 on the opposite side of the tilt direction is elongated, and the elastic traction member 4 on one side of the tilt direction is shortened. Therefore, the pulling force of the elastic traction member 4 on the opposite side of the tilt direction on the power-assisting connecting member 3 is greater than the pulling force of the elastic traction member 4 on the same side of the tilt direction, and a pulling force is generated on the power-assisting connecting member 3 in the opposite side of the tilt direction to act on the upper connecting frame 1 to correct the scoliosis of the spine. Therefore, the multi-dimensional spinal imbalance corrector of the present embodiment can realize the correction of multi-dimensional spinal imbalance. The power-assisting connecting member 3 is connected to the lower connecting frame 2 through 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.

[0021] Combination 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 may be an elastic rope body.

[0022] Combination Figure 4 and Figure 5 As shown, in this embodiment, a tension regulator 5 is also included. The tension regulator 5 includes a pair of coaxially connected wire wheels 51 and an adjusting handle 53. The wire wheels 51 and the adjusting handle 53 are connected in a transmission manner. The adjusting handle 53 is used to drive the wire wheels 51 to rotate. A pair of cables 41 are connected to the pair of wire wheels 51 respectively. The tension regulator 5 also includes a locking mechanism, which is used to lock the wire wheels 51 to prevent the tension on the cables 41 from driving the wire wheels 51 to rotate. In this embodiment, the adjusting handle 53 is used to drive the wire wheels 51 to rotate. The adjusting handle 53 drives the wire wheels 51 to rotate to retract and release the cables 41, so as to adjust 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 wire wheels 51. In this embodiment, the locking mechanism includes a worm wheel 521 and a worm 522 that mesh with each other. The wire wheels 51 are connected in a transmission manner to the worm wheel 521, and the worm 522 is connected in a transmission manner to the adjusting handle 53. The power transmission for driving the wire wheel 51 to rotate is in order: the adjusting handle 53, the worm 522, the worm wheel 521, and the wire wheel 51. The worm 522 always locks the worm wheel 521, which has a self-locking effect, and there is no need to perform a locking operation separately, which is convenient to operate. In this embodiment, in order to improve compactness, the worm wheel 521 and a pair of wire wheels 51 are coaxially connected, and the worm 522 is coaxially connected to the adjusting handle 53, and the adjusting handle 53 is a knob.

That is, the wire wheel 51, the adjustment handle 53 and the locking mechanism are all installed on the lower connecting frame 2, which has the advantage of high integration compared to the tension regulator 5 independently arranged on the lower connecting frame 2. 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 front end of the lumbar support 21 contacting the back waist position 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, thereby applying a forward rotation couple to the pelvis, which can simultaneously correct the excessive pelvic rotation caused by the imbalance of the sagittal plane of the spine.

[0026] Combination Figure 3 As shown, in this embodiment, it also includes a roller 311 rotatably mounted on one end of the power-assisting connecting member 3 near the upper connecting frame 1.

A pair of rollers 311 are respectively rolled in the sliding cavities 10 on both sides, and the rollers 311 are always separated from the bottom end of the sliding cavity 10. Different from the general articulation of the power-assisting connecting member 3 directly with the upper connecting frame 1, the power-assisting connecting member 3 contacts the side wall of the sliding cavity 10 through the rollers 311 to pull the upper connecting frame 1. Since the rollers 311 are always separated from the bottom end of the sliding cavity 10, they cannot transmit longitudinal tension to the upper connecting frame 1, so as to prevent the power-assisting connecting member 3 from transmitting the downward tension of the cable 41 to the upper connecting frame 1 to generate a downward compression force 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 body 31 and the sliding cavity 10 causing longitudinal pressure.

In this embodiment, the first rod body 31 is a tubular body sleeved on the second rod body 32, and the first rod body 31 and the second rod body 32 are axially locked by a locking pin.

[0028] Combination 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 at 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 corresponding back straightening state.
