Description

Technical Field

[0001] The invention relates to the technical field of medical care equipment, and in particular to a vertebra-simulating waist support fixator. Background Art

[0002] Low back pain refers to pain and discomfort covering the area between the twelfth rib and the iliac crest, often accompanied by pain radiating to the buttocks and lower extremities. As a common musculoskeletal injury of the back, low back pain has a lifetime prevalence of up to 84%, and is one of the main causes of functional impairment and years of disability worldwide, bringing distress and heavy economic burdens to patients, their families, and even the country and society. Research supports that low back pain is characterized by a combination of physical, psychological, and social dysfunction. More critically, despite the existence of a wide range of therapeutic interventions, up to 71% of patients with low back pain have not fully recovered after one year, pointing to the challenges in the management of low back pain. Most cases of low back pain (85% to 90%) are classified as "nonspecific", that is, the cause of the pain cannot be accurately attributed to any specific pathological anatomical structure, which further increases the complexity of treatment.

[0003] The ANAMT guidelines released in 2020 pointed out that the use of straps, lumbar supports or braces can help prevent occupational low back pain. The use of lumbar fixation belts is particularly important in the self-management and exercise of patients with low back pain. It can help patients with low back pain to perform light exercises and gradually resume daily activities, preventing recurrence and new onset.

[0004] The support systems of existing waist belts on the market generally have the following disadvantages:

[0005] 1. There is only a webbing at the vertebrae support position, and no other supporting structure. When standing or sitting upright, it is difficult for the webbing to directly contact the lumbar spine, and it is unable to fully fix and lift the spine, and the supporting force is limited.

[0006] 2. The flat design cannot effectively support the natural curve of the waist and back. Regardless of the material, this flat design is difficult to fit the three-dimensional structure of the spine and is likely to cause local compression and discomfort to the intervertebral disc.

[0007] 3. Due to the unreasonable design of the support structure, the force on the vertebral support position is often insufficient. This results in the inability to effectively transfer the weight of the waist and provide sufficient support for the spine.

[0008] 4. Excessive or insufficient restriction on the movement of the waist in all directions affects the user's freedom of movement and cannot effectively enhance the stability of the spine and assist in posture control and waist training. Summary of the invention

[0009] In view of the above-mentioned deficiencies in the prior art, the present invention provides a vertebral imitation lumbar support fixator, the purpose of which is to solve the problems raised in the above-mentioned background technology.

[0010] In order to achieve the above-mentioned object of the invention, the technical solution adopted by the present invention is:

[0030] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0031] like Figures 1 to 3As shown, a bionic vertebrae-supporting lumbar fixator comprises a tension belt 1 and a supporting component 2. A bionic vertebrae plate is arranged at the corresponding position of the vertebrae. The upper edge of the bionic vertebrae plate is 75-95 mm long, typically 90 mm, and is arranged according to the midpoint of the distance between the outer edge of the lumbar iliocostalis muscle and the horizontal position of the first vertebral body of 7.27±0.8 cm; the lower edge of the bionic vertebrae plate is 55-75 mm long, typically 70 mm, and is arranged according to the lower transverse diameter of the fifth lumbar vertebra of 5.60±0.15 cm; the overall height is 140-180 mm, typically 160 mm, and can cover the first to fifth lumbar vertebrae.

[0032] According to the physiological curvature of 26° at the lumbar stage of the spine, the bionic vertebral plate is designed as a 26° inverted C-shaped surface, on which a convex portion 3 with a width of 22-34mm, typically 28mm, is arranged to accommodate the lumbar spinous processes in different motion or static states, while restoring the normal physiological curvature of the lumbar spine and limiting the scoliosis of the lumbar segments, and also preventing local compression of the vertebral body.

[0033] The posterior convex portion 3 is provided with five hollows 4 with a width of 10-14 mm, typically 12 mm, and a height of 16-24 mm, typically 20 mm, to correspond to the spinous processes of the first to fifth lumbar vertebrae to prevent compression or restriction of the spinous process, a bony landmark. The spacing between adjacent hollows 4 is 7-13 mm, typically 10 mm, and is set according to the average intervertebral space of the human body.

[0034] In order to prevent insufficient or uneven force support for the lumbar vertebral segments, the bionic vertebral plate is set to a curved trapezoidal structure that is wide at the top and narrow at the bottom according to the principle of mechanics. The force-bearing area is increased on the basis of conforming to the physiological structure of the lumbar spine, and the pressure on the muscles around the lumbar vertebrae such as the multifidus muscle, the longissimus thoracis muscle, and the iliocostalis lumborum is reduced. At the same time, two bionic cartilage support strips 5 with a width of 15-25mm, typically 20mm, and lengths of 180-220mm, typically 200mm and 160-200mm, typically 180mm, are set on both sides of the bionic vertebral plate to provide support for the latissimus dorsi and the internal and external oblique muscles of the abdomen.

[0035] In order to avoid affecting the daily activities of the lumbar spine, the bionic vertebral plate and the bionic cartilage support strip 5 are made of modified PP with a certain flexibility. The bionic vertebral plate is provided with reinforcing ribs 6 with a length of 100-160 mm, typically 130 mm, which can assist in posture control while enhancing the stability of the spine.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
