Description

Technical Field

[0001] This utility model relates to the field of medical and health care device technology, and in particular to a vertebral support lumbar fixation device. Background Technology

[0002] Lower back pain refers to pain and discomfort in the area between the twelfth rib and the iliac crest, often radiating to the buttocks and lower limbs. As a common musculoskeletal injury of the back, lower back pain has a lifetime prevalence of up to 84%, causing distress and a heavy economic burden on patients, their families, and society. Research supports the idea that lower back pain is characterized by a combination of physical, psychological, and social functional impairments. Crucially, despite extensive treatment interventions, up to 71% of lower back pain patients have not fully recovered after one year, highlighting the challenges in lower back pain management. The majority of lower back pain cases (85%–90%) are classified as "nonspecific," meaning the cause of the pain cannot be definitively attributed to any specific pathological anatomical structure, further complicating treatment.

[0003] The ANAMT guidelines published in 2020 indicate that back braces, lumbar supports, or braces can help prevent occupational lower back pain. The use of lumbar support belts is particularly important in the self-management and exercise of patients with lower back pain, helping them to engage in light exercise and gradually resume daily activities, preventing recurrence and new onset.

[0004] The support systems currently available on the market that come with lumbar support belts generally have the following disadvantages:

[0005] 1. Only webbing is provided at the vertebral support position, lacking other support structures. When standing or sitting upright, the webbing has difficulty making direct contact with the lumbar spine, which cannot adequately fix and support the spine, resulting in limited support strength.

[0006] 2. The flat design cannot effectively support the natural curve of the lower back. Regardless of the material, this flat design is difficult to conform to the three-dimensional structure of the spine, and can easily cause local pressure and discomfort to the intervertebral discs.

[0007] 3. Due to unreasonable support structure design, the stress on the vertebral support points is often insufficient. This results in the inability to effectively transfer the weight of the lumbar region and provide adequate 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 fails to effectively enhance spinal stability and assist in posture control and waist exercise. Utility Model Content

[0009] In view of the above-mentioned shortcomings in the prior art, the present invention provides a vertebral support lumbar fixation device, the purpose of which is to solve the problems mentioned in the background art.

[0010] To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows:

[0011] A vertebral support lumbar fixation device includes a resistance band and a support component. The support component is fixedly disposed in the middle of the resistance band. The support component includes a bionic vertebral plate with an upper edge width of 75mm-95mm, a lower edge width of 55mm-75mm, and a height of 140mm-180mm. The bionic vertebral plate has an overall curvature of 26° and a posterior convex portion with a width of 22mm-34mm. The posterior convex portion has five hollows, each 10mm-14mm wide and 16mm-24mm high, with a spacing of 7mm-13mm between adjacent hollows. Two bionic cartilage support strips, each 15mm-25mm wide and 180mm-220mm and 160mm-200mm long respectively, are provided on each side of the bionic vertebral plate. The tension band is fixedly connected to the bionic cartilage support strips. The bionic vertebral plate is provided with reinforcing ribs, each 100mm-160mm long.

[0012] Furthermore, the width of the upper edge of the bionic vertebral plate is 90mm.

[0013] Furthermore, the width of the lower edge of the bionic vertebral plate is 70mm.

[0014] Furthermore, the height of the bionic vertebral plate is 160mm.

[0015] Furthermore, the rear convex portion has a width of 28mm.

[0016] Furthermore, the width of the cutout is 12mm and the height is 20mm.

[0017] Furthermore, the distance between adjacent cutouts is 10mm.

[0018] Furthermore, the bionic cartilage support strip has a width of 20mm and lengths of 200mm and 180mm, respectively.

[0019] Furthermore, the length of the reinforcing rib is 130mm.

[0020] Furthermore, the biomimetic cartilage support strip is made of flexible modified PP material.

[0021] The beneficial effects of this utility model are as follows:

[0022] This utility model discloses a vertebral support lumbar fixation device. The bionic vertebral plate can cover the first to fifth lumbar vertebrae. The posterior convex part can accommodate the spinous processes of the lumbar vertebrae in different motion or static states. While restoring the normal physiological curvature of the lumbar spine, it restricts lateral convexity of the lumbar segments and prevents local compression of the vertebral body. The hollow part can correspond to the spinous processes of the first to fifth lumbar vertebrae to prevent compression or restriction of this bony landmark. The bionic vertebral plate is set as a curved trapezoidal structure that is wider at the top and narrower at the bottom. While conforming to the physiological structure of the lumbar spine, it increases the stress area and reduces pressure on the muscles around the lumbar vertebrae, such as the multifidus, longissimus thoracis, and iliocostalis muscles. The bionic cartilage support strip provides support for the latissimus dorsi and internal and external oblique muscles. The reinforcing ligaments enhance the stability of the spine and assist in posture control. Attached Figure Description

[0028] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0029] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagrams, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0030] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0031] like Figures 1 to 3As shown, a vertebral support lumbar fixation device includes a tension band 1 and a support component 2. A biomimetic vertebral plate is set at the corresponding position of the vertebra. The upper edge of the plate is 75-95mm long, typically 90mm, based on the midpoint of the distance between the outer edge of the iliocostalis muscle and the first vertebral body at the horizontal position, which is 7.27±0.8cm. The lower edge is 55-75mm long, typically 70mm, based on the lower transverse diameter of the fifth lumbar vertebra, which is 5.60±0.15cm. The overall height is 140-180mm, typically 160mm, and can cover the first to fifth lumbar vertebrae.

[0032] Based on the physiological curvature of 26° in the lumbar spine, the bionic vertebral plate is designed as a 26° inverted C-shaped surface, with a posterior convex portion 3 on it, which is 22-34mm wide, typically 28mm, to accommodate the spinous processes of the lumbar vertebrae in different motion or resting states. This not only restores the normal physiological curvature of the lumbar spine but also limits lateral convexity of the lumbar segments and prevents local compression of the vertebral body.

[0033] The posterior convex portion 3 has five openings 4, each 10-14mm wide (typically 12mm) and 16-24mm high (typically 20mm), to correspond to the spinous processes of the first to fifth lumbar vertebrae, preventing compression or restriction of these bony landmarks. The spacing between adjacent openings 4 is 7-13mm, typically 10mm, based on the average intervertebral space in the human body.

[0034] To prevent insufficient or uneven support of the lumbar vertebral segments, the bionic vertebral plate is designed as a curved trapezoidal structure that is wider at the top and narrower at the bottom, based on the principles of mechanics. This increases the stress-bearing area while conforming to the physiological structure of the lumbar spine, reducing pressure on the muscles around the lumbar vertebrae, such as the multifidus, longissimus thoracis, and iliocostalis. At the same time, two bionic cartilage support strips are set on both sides of the bionic vertebral plate, with a width of 15-25mm (typically 20mm) and lengths of 180-220mm (typically 200mm) and 160-200mm (typically 180mm), respectively, to provide support for the latissimus dorsi and the internal and external oblique muscles.

[0035] To avoid affecting 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 degree of flexibility. The bionic vertebral plate uses reinforcing ribs 6 with a length of 100-160mm, typically 130mm, which can enhance spinal stability and assist in posture control.

[0036] The above description is only a preferred embodiment of this utility model patent and is not intended to limit this utility model patent. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
