Description

Technical Field

[0001] This invention relates to the field of medical devices, and more particularly to a lumbar intervertebral disc traction and repositioning device, which can be used for rehabilitation treatment of lumbar muscle strain and degenerative diseases. Background Technology

[0002] Lumbar muscle strain and degenerative diseases are common clinical conditions, such as lumbar muscle strain, lumbar disc herniation, and lumbar spinal stenosis. There are many causes of lumbar diseases, such as poor sitting and standing posture, prolonged bending or heavy physical labor, long hours of desk work, and frequent looking down at mobile phones. These factors have led to a sharp increase in the incidence of lumbar diseases and have become one of the common factors affecting people's quality of life.

[0003] Currently, the main treatments for lumbar spine disorders include medication, physical therapy, and surgery. Due to the significant limitations and risks associated with medication and surgery, physical therapy is more commonly preferred, with lumbar traction being the most common method. Lumbar traction increases the intervertebral space, creating negative pressure within it. Simultaneously, it tightens the posterior ligaments, facilitating the reduction of herniated nucleus pulposus and the opening of facet joints, relieving tension with nerve roots. Traction also allows the lumbar spine to rest fully, reducing the stimulation of movement, aiding in the absorption and resolution of tissue congestion and edema, relieving muscle spasms, and reducing intervertebral pressure.

[0004] Chinese invention patent application CN210910602912.9 discloses a lumbar disc herniation treatment device. This device, with its upright structure, can perform vertical traction, overcoming the drawbacks of existing lumbar traction beds. However, this device still has the following drawbacks in use:

[0005] 1. When pulling upwards, the axillary support plate of the chest fixation device is held under both sides of the armpit. Pulling upwards will put great pressure on the axillary nerve, increasing the patient's pain and reducing the user experience.

[0006] 2. When the human body is standing on the ground, the lumbar traction and torsion device needs to pull downwards. The chest fixation device needs to lift the human body upwards first to leave space for downward traction. At this time, the axillary support plate has to bear the weight of the human body. The strength of the axillary support plate and the power of the drive motor are required to be high, and the pressure on the axillary nerve is very large. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide a lumbar intervertebral disc traction and repositioning device that adopts a supine upper body and a standing lower body form to avoid compression of the armpit when performing traction while standing.

[0008] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0009] A lumbar intervertebral disc traction and repositioning device, characterized in that it comprises:

[0010] Base;

[0011] The first traction seat includes a first support rod and a traction plate. The first support rod is vertically arranged and its lower end is fixed to the base. The height of the first support rod is adjustable. The traction plate is rotatably arranged on the upper end of the first support rod. Under the drive of the drive unit A, the traction plate can be tilted and locked. The traction plate has an upper body fixation garment that can be worn on the patient's upper body.

[0012] The second traction seat includes a second support rod and a leg swing device. The second support rod is passively extendable under force, and its lower end rotatably passes through a base and is connected to a drive unit B that drives its rotation. The leg swing device includes a leg plate with a thigh support garment that can be worn on the patient's thigh. The leg plate is rotatably fixed to the top of the second support rod and can reciprocate left and right under the drive of the drive unit C.

[0013] A foot traction device includes two foot fixation boots that can be worn on the patient's foot. Each foot fixation boot has a traction strap connected to its bottom. The traction strap is elastic, passes downward through a base, and is wound around a reel. Both ends of the reel are rotatably fixed to the bottom of the base. A drive unit D for driving the rotation of each reel is connected to one end of the reel.

[0014] A further technical solution is that the base has an adjustment slide rail opened in the front-back direction, the lower end of the first support rod passes through the adjustment slide rail and is connected to a drive unit E that drives it to move along the adjustment slide rail.

[0015] A further technical solution is that the upper sides of the traction plate are equipped with handles.

[0016] A further technical solution is that the upper body fixing garment includes two upper body straps, which are placed on the left and right sides of the traction plate. One end of the upper body strap is slidably connected to the traction plate and can slide up and down along the traction plate. The other ends of the two upper body straps can be connected to each other to form a closed loop.

[0017] A further technical solution is that the traction plate has a notch in the middle of its lower part, and two rotating rollers are rotatably fixed in the notch. The two rotating rollers are arranged vertically and connected by a traction belt. One of the rollers is connected to a drive unit F that drives its rotation. When the patient lies on the traction plate, the traction belt can contact the patient's abdomen.

[0018] A further technical solution is that the traction plate also has a massager, which has two massage arms, which are placed on the left and right sides of the traction plate. Each massage arm includes a first arm rod, a second arm rod, and a massage head. One end of the first arm rod is connected to the traction plate, and the other end is rotatably connected to one end of the second arm rod, forming a "┌" shape with the second arm rod. The massage head is fixed to the free end of the second arm rod, and the second arm rod can swing around the first arm rod as the center under the drive of the drive unit G.

[0019] A further technical solution is that the first arm is telescopic.

[0020] A further technical solution is that the first arm can slide up and down along the traction plate and lock under the drive of the drive unit H.

[0021] A further technical solution is that the thigh fixation garment includes two sets of fixation components, which are respectively disposed on the left and right sides of the leg plate. Each fixation component includes a rubber plate and a thigh strap. The rubber plate is sleeved on the leg plate, and the two rubber plates can move closer or further apart from each other. One end of the thigh strap is fixed to the corresponding rubber plate, and the other ends of the two thigh straps can be connected to each other to form a closed loop.

[0022] A further technical solution is that the leg plate includes a fixed plate and a movable plate. The fixed plate is rotatably connected to the rotating shaft at the top of the second support rod. The driving part C includes a transverse screw and a transverse slider that is threadedly engaged with it. The transverse screw is rotatably fixed on the fixed plate and connected to a motor that drives its rotation. The transverse slider is fixed to the movable plate, and the thigh fixing garment is connected to the movable plate.

[0023] The beneficial effects of adopting the above technical solution are as follows:

[0024] This device employs a supine upper body and a standing lower body posture for traction rehabilitation therapy. During use, the patient lies prone or supine on the traction board and is secured to it with an upper body support garment, while the lower body stands and is secured to the leg swing device. This design avoids stress on the patient's armpits during traction.

[0025] By adjusting the height of the first traction seat, the second traction seat rises and locks in place, allowing the patient's legs to hang down naturally. Traction is applied using the patient's own weight, which is relatively safe and can be used as an adjunct treatment for lumbar diseases.

[0026] Raising the first traction seat further provides upward traction to the patient and the lumbar spine, which increases the intervertebral space. This widening creates negative pressure within the intervertebral space and tightens the posterior ligaments, facilitating the reduction of the herniated nucleus pulposus and the opening of the facet joints, thus relieving tension between the herniated nucleus pulposus and the nerve roots.

[0027] The purpose of vertical traction is to pull apart the anterior intervertebral disc annulus fibrosus, thereby inducing the bulging disc to retract, thus achieving the goal of treating the initial stage of disc herniation or bulging. In the early stage of disc herniation or bulging, the annulus fibrosus of the intervertebral disc has not aged and still retains elasticity, so there is room for rebound under proper external force exercise.

[0028] Moreover, the traction board can be tilted up and down, adjusting the angle between the patient's upper and lower body, which can facilitate multi-directional bending of the lumbar spine in lumbar patients.

[0029] After the patient raises both legs off the ground, the foot traction device can be activated to apply traction force to the patient's feet. By stretching the two traction straps simultaneously or alternately, the patient's legs can be pulled downwards, which also increases the intervertebral space.

[0030] The leg swing device can facilitate lateral movement and twisting of the lumbar spine in patients with lumbar spine problems, restore intervertebral spacing, and provide targeted strengthening exercises for the lumbar muscles, thereby relieving lumbar pain. Attached Figure Description

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0039] like Figures 1-3 As shown, a lumbar disc traction and repositioning device includes a base 10 placed on a bottom surface, on which a first traction seat, a second traction seat, and a foot traction device are fixed. It can perform vertical traction and lateral twisting of the lumbar spine to restore intervertebral disc spacing, and can also provide targeted strengthening exercises for the lumbar muscles, thereby strengthening the lumbar muscles and relieving lower back pain.

[0040] The first traction seat includes a first support rod 21 and a traction plate 22, which can form a T-shaped structure. The first support rod 21 is vertically arranged, and its lower end is fixed to the base 10. The height of the first support rod 21 is adjustable and can be actively adjusted using an electric push rod or a cylinder. A horizontal first rotating rod is rotatably fixed to the top of the first support rod 21 via a bearing. The traction plate 22 is fixed to the first rotating rod, achieving a rotatable connection with the upper end of the first support rod 21. One end of the first rotating rod is connected to a drive unit A that drives its rotation. The drive unit A can be a rotary motor. Under the drive of the drive unit A, the traction plate 22 can be tilted and locked. The traction plate 22 can tilt, adjusting the angle between the patient's upper and lower body, and can facilitate multi-directional bending of the lumbar spine in lumbar patients.

[0041] The traction plate 22 has an upper body fixation garment 23 that can be worn on the patient's upper body. The function of the upper body fixation garment 23 is to fix the patient's upper body to the traction plate 22, so that the patient's upper body can move with the traction plate 22.

[0042] The upper body fixation garment 23 includes two upper body straps, which are placed on the left and right sides of the traction plate 22. There are first grooves on both sides of the traction plate 22. One end of the upper body strap has a first slider that slides in the first groove, so that the upper body strap is slidably connected to the traction plate 22 and can slide up and down along the traction plate 22 to adjust to a suitable position according to the patient's body shape. The other ends of the two upper body straps can be connected to each other to form a closed loop by Velcro or buckles.

[0043] In addition, there are handles 221 on both sides of the upper part of the traction board 22. When the patient lies on the traction board 22, he / she can hold the handles 221 with both hands and move with the traction board 22 better.

[0044] The second traction seat includes a second support rod 31 and a leg swinger 32. The second support rod 31 can passively extend and retract under force and can be in the form of a sleeved inner tube and an outer tube. The outer tube has a locking hole, and the inner tube has a long hole along its length. The locking hole corresponds to the long hole, and a bolt and nut assembly is connected between the locking hole and the long hole. When the nut is loosened, the outer tube can slide freely, and when the nut is tightened, the outer tube and the inner tube are locked. The lower end of the second support rod 31 rotatably passes through the base 10 and is connected to a drive unit B that drives its rotation. The drive unit B can be a rotary motor.

[0045] The leg swing device 32 includes a leg plate 321, on which a thigh fixation garment is attached for wearing on the patient's thigh. The function of the thigh fixation garment is to secure the patient's thigh to the leg plate 321, allowing the thigh to move with the leg plate 321. The thigh fixation garment includes two sets of fixing components, located on the left and right sides of the leg plate 321. Each fixing component includes a rubber plate 322 and a thigh strap. The rubber plates 322 are fitted onto the leg plate 321, and the two rubber plates 322 can move closer or further apart. One end of the thigh strap is fixed to the corresponding rubber plate 322, and the other ends of the two thigh straps can be connected to each other via Velcro or buckles to form a closed loop. The distance between the two rubber plates 322 is adjustable, allowing the thigh fixation garment to better cover the patient's thigh. After adjustment, the rubber plates 322 can be locked to the leg plate 321 for stability. Various locking methods exist between the rubber plates 322 and the leg plate 321, such as bolt and nut assemblies, which will not be elaborated here.

[0046] The leg plate 321 is rotatably fixed to the top of the second support rod 31 and can passively rotate with the traction plate 22 to adjust to a suitable posture. The second support rod 31 has a limiting rod that restricts the lower limit of the leg plate 321's clockwise rotation. The leg plate 321 can reciprocate left and right under the drive of the drive unit C. Specifically, the leg plate 321 includes a fixed plate and a movable plate. The fixed plate is rotatably connected to a rotating shaft at the top of the second support rod 31, and the rotating shaft is parallel to the first rotating rod. The drive unit C includes a transverse screw and a transverse slider threaded to it. The transverse screw is rotatably fixed to the fixed plate and connected to a motor that drives its rotation. The transverse slider is fixed to the movable plate, and the thigh support garment is connected to the movable plate.

[0047] When the drive unit B starts, it drives the second support rod 31 to rotate back and forth at a certain angle, which causes the leg swinger 32 to rotate the leg back and forth. When the drive unit C moves, the transverse screw rotates in both directions, which causes the leg swinger 32 to move the leg back and forth horizontally.

[0048] The foot traction device includes two foot fixation boots 41, which can be worn on the patient's feet to fix both feet to the foot traction device. The toe area of ​​the foot fixation boots 41 can be notched to expose the patient's toes, regardless of size. A traction strap 42 is connected to the bottom of each foot fixation boot 41. The traction strap 42 is elastic, passes downward through the base 10, and is wound around a reel 43. Both ends of the reel 43 are rotatably fixed to the bottom of the base 10. A drive unit D, which can be a rotary motor, is connected to one end of each reel 43 to drive its rotation. The rotary motor drives the reel 43 to rotate forward and backward, causing the traction strap 42 to reciprocate in a pulling motion on the patient's lower limbs.

[0049] This device employs a supine upper body and a standing lower body posture for traction rehabilitation treatment. During use, the patient's upper body lies prone or supine on the traction board 22 and is secured to it by an upper body fixation garment 23, while the lower body stands and is fixed to the leg swing device 32. This avoids stress on the patient's armpits during traction.

[0050] By adjusting the height of the first traction seat, the second traction seat rises and locks in place, allowing the patient's legs to hang down naturally. Traction is applied using the patient's own weight, which is relatively safe and can be used as an adjunct treatment for lumbar diseases.

[0051] Raising the first traction seat further provides upward traction to the patient and the lumbar spine, which increases the intervertebral space. This widening creates negative pressure within the intervertebral space and tightens the posterior ligaments, facilitating the reduction of the herniated nucleus pulposus and the opening of the facet joints, thus relieving tension between the herniated nucleus pulposus and the nerve roots.

[0052] The purpose of vertical traction is to pull apart the anterior intervertebral disc annulus fibrosus, thereby inducing the bulging disc to retract, thus achieving the goal of treating the initial stage of disc herniation or bulging. In the early stage of disc herniation or bulging, the annulus fibrosus of the intervertebral disc has not aged and still retains elasticity, so there is room for rebound under proper external force exercise.

[0053] After the patient raises both legs off the ground, the foot traction device can be activated to apply traction force to the patient's feet. Through the simultaneous or alternating stretching of two traction straps 42, the patient's legs can be pulled downwards, which also increases the intervertebral space.

[0054] The leg swinger 32 can move and twist the waist of lumbar patients, restore the intervertebral space, and can perform targeted strengthening exercises for the waist muscles, thereby relieving waist pain.

[0055] The base 10 has an adjustment slide 11 extending in the front-to-back direction. The lower end of the first support rod 21 passes through the adjustment slide 11 and is connected to a drive unit E that drives it to move along the adjustment slide 11. Specifically, a screw is rotatably fixed on the base plate. One end of the screw is connected to a motor that drives it to rotate, and the other end of the screw is threadedly connected to the lower end of the first support rod 21. By rotating or reversing the screw, the first support rod 21 can be driven to move along the adjustment slide 11 to adjust the distance between the first traction seat and the second traction seat, thereby tractioning the lumbar spine.

[0056] The traction plate 22 has a notch in its lower center, within which two rotating rollers are rotatably fixed. The two rollers are arranged vertically and are connected by a traction belt 222. One of the rollers is connected to a drive unit F, which can be a rotary motor, to rotate it. When the patient lies on the traction plate 22, the traction belt 222 comes into contact with the patient's abdomen. The drive unit F rotates the traction belt 222, thus massaging the patient's abdomen.

[0057] The traction plate 22 also includes a massager 50, which has two massage arms positioned on the left and right sides of the traction plate 22. Each massage arm includes a first arm 51, a second arm 52, and a massage head 53. The massage head 53 can employ electromagnetic massage, making it a physiotherapy device for self-treatment and health maintenance. This physiotherapy device consists of a permanent magnet and a motor with an eccentric weight; changing the motor speed changes the massage frequency. Therefore, it provides both mechanical massage and pulsating magnetic field effects. The device has a simple structure, is easy to adjust, convenient to use, and safe and reliable. Alternatively, intermittent vibration hammer massage can be used, including a housing, a push rod, a cam linkage mechanism, and a massage section. An infrared lamp can be added around the massage head 53.

[0058] One end of the first arm 51 is connected to the traction plate 22, and the other end is rotatably connected to one end of the second arm 52, forming a "┌" shape. The massage head 53 is fixed to the free end of the second arm 52. Driven by the drive unit G, the second arm 52 can swing around the first arm 51 as the center. The drive unit G can be fixed to the upper end of the first arm 51 and uses a swinging hydraulic cylinder. By driving the second arm 52 with the massage head 53 to swing through the drive unit G, the massage range on the patient's back can be expanded, including the back and buttocks.

[0059] Furthermore, the first arm 51, driven by the drive unit H, can slide up and down along the traction plate 22 and lock. Screws are rotatably mounted on both sides of the traction plate 22, with motors connected to the screws to drive their rotation. Second sliders are threaded onto the screws, and the lower end of the first arm 51 is fixed to the second sliders. The movement of the first arm 51 via the second sliders further expands the massage range. Moreover, the first arm 51 is extendable and retractable to accommodate patients of different body shapes and varying massage intensities.

[0060] like Figure 4 and Figure 5 As shown, the traction plate 22 can also be configured as two pieces: an upper plate 223 and a lower plate 224. The upper plate 223 is driven by the drive unit I and can move away from or closer to the lower plate 224 to achieve traction on the vertebral body. Moreover, under the drive of the drive unit J, the upper plate 223 and the lower plate 224 can move alternately to the left and right, improving the training of the patient's vertebral body.

[0061] Specifically, the upper plate 223 has a transverse second sliding groove 2231 on its back side. A top block 2232 slides within the second sliding groove 2231. The top block 2232 has a convex cross-section, which prevents it from dislodging from the second sliding groove 2231. The driving unit I is an electric telescopic rod 225, whose telescopic end is fixed to the top block 2232 and its fixed end is fixed to the lower plate 224. The upper plate 223 moves up and down by extending and retracting the electric telescopic rod 225.

[0062] An H-shaped support frame 2261 is provided on the back of the traction plate 22. The support frame is not connected to the traction plate 22. The middle rod of the support frame is fixed to the first rotating rod on the first support rod 21. A lower screw 2241 is rotatably fixed at the lower end of the support frame. A lower slider 2242 is threaded onto the lower screw 2241. The lower slider 2242 is fixed to the back of the lower plate 224. A motor is connected to one end of the lower screw 2241 to drive its rotation. By driving the lower screw 2241 to rotate forward or backward by the motor, the lower slider 2242 can drive the lower plate 224 to move to the right or left. The support frame 2261 has vertical slides on both sides of the upper end. Adjustable sliders are slidably arranged in the slides. An upper screw 2233 is rotatably fixed between the two adjustable sliders. The upper slider 2234 is threadedly connected to the upper screw 2233. The upper slider is fixed to the back of the upper plate 223. A motor is connected to the upper screw 2233 to drive its rotation. By driving the upper screw 2233 to rotate forward or backward by the motor, the upper slider 2234 can drive the upper plate 223 to move to the right or left.

[0063] The above are merely preferred embodiments of the present invention. Any simple modifications, variations, and equivalent substitutions made by any person based on the content of the present invention shall fall within the protection scope of the present invention.
