Description

Technical Field

[0001] The utility model relates to the technical field of spinal orthotics, in particular to a knob-type orthosis for scoliosis. Background Art

[0002] The spine is the main supporting structure of the human body, including the cervical spine, thoracic spine and lumbar spine. Scoliosis refers to the deviation of several vertebrae from the midline of the body, resulting in three-dimensional curvature, accompanied by coronal scoliosis, rotation of the spine, increase or decrease of sagittal lordosis, rotation and tilt deformity of the ribs and pelvis, and abnormalities of the paravertebral ligaments and muscles, forming a spinal deformity with an arc. At present, the treatment methods for scoliosis are mainly divided into exercise therapy, orthosis treatment and surgical treatment. Generally, for patients with scoliosis, orthosis should be used for treatment before the scoliosis develops to a severe stage. The straps of traditional scoliosis orthosis are used to adjust the tightness of the orthosis and ensure the effect of spinal correction. The orthosis has always been connected by Velcro. The use of Velcro is cumbersome, and it is often too tight, too loose, or loose when walking and exercising. Children usually stick Velcro with the help of their parents. Once opened, many children find it difficult to stick it to the position required by the doctor, causing a lot of inconvenience. Utility Model Content

[0034] Example 1

[0035] This embodiment 1 provides a knob-type orthosis for scoliosis, comprising:

[0036] The orthosis body 1 is a longitudinally opened cylindrical structure that fits the human spine segment, and openings are arranged on both sides of the orthosis body 1.

[0037] Knob buckle 2, a knob buckle 2 is provided on one side of the orthosis body 1. The knob buckle includes a knob 201, a transmission ratchet 202, a limit ratchet 203, a rope winding ratchet shaft 204 and a fixed shaft 205 from top to bottom. The first end of the fixed shaft 205 is connected to the orthosis body 1 through 3D printing technology, the second end of the fixed shaft 205 is connected to the transmission ratchet 202, the rope winding ratchet shaft 204 is sleeved on the fixed shaft 205, and the limit ratchet 203 is sleeved on the outer side of the rope winding ratchet shaft 204. The transmission ratchet 202 is connected to the rope winding ratchet shaft 204, and the limit ratchet 203 is also sleeved outside the transmission ratchet 202. The upper outer side of the limit ratchet 203 is movably connected to the inner side of the knob 201. The transmission ratchet 202 and the rope winding ratchet shaft 204 are coaxially connected through ratchets that match each other.

[0038] The pull rope mechanism 3 is provided with two groups, and the two groups of pull rope mechanisms 3 are respectively located on both sides of the orthosis body 1. The two sides of the orthosis body 1 are connected by the pull rope mechanism 3, and the pull rope mechanism 3 includes a tension rope 301 wound around the outer surface of the rope winding ratchet shaft 204 and a tension hole 302 provided on the orthosis body 1 for the tension rope 301. The tension rope 301 is inserted into the tension hole 302. The tension rope 301 connects the two groups of pull rope mechanisms 3 and the rope winding ratchet shaft 204.

[0039] The upper surface of the knob 201 is provided with a pattern for increasing friction. The fixed shaft 205 is composed of a flat plate 2051 connected to the orthosis body 1 and a connecting piece 2052 perpendicular to the flat plate 2051. Among them, a U-shaped groove is provided on the side of the flat plate 2051, and the U-shaped groove is provided with a limiting protrusion. The upper end of the connecting piece 2052 is connected to the transmission ratchet 202. The limiting ratchet 203 is provided with an engaging piece 2031, and the engaging piece 2031 is engaged with the limiting protrusion. The rope winding ratchet shaft 204 includes an upper bottom plate, a lower bottom plate and an intermediate layer connecting the upper bottom plate and the lower bottom plate, which are engaged with the limiting ratchet 203, and the tension rope 301 is wound around the outer surface of the intermediate layer of the rope winding ratchet shaft 204.

[0040] Here’s how it works:

[0041] By turning the knob 201, the force applied passes through the transmission ratchet 202 and the rope winding ratchet shaft 204 in sequence, thereby driving the tension rope 301 to tighten and rebound, thereby applying pressure to the orthosis body 1 to achieve a correction effect.

[0042] The fixed shaft 205 is located at the bottom of the knob buckle 2 and is connected to the orthosis body 1 to provide a fulcrum for the device. The outer surface of the middle area of ​​the rope winding ratchet shaft 204 is wound with a tension rope 301, and the tightness of the tension rope 301 can be adjusted by the knob 201 to lock the tension rope 301. The knob 201 has a relatively large area, and the surface is provided with a pattern that increases the friction force. It does not take too much physical effort to turn the knob 201. The operation is simple and the size of the orthosis force can be easily adjusted. At this time, due to the unidirectional rotation characteristics of the knob 201, the rope winding ratchet shaft 204 cannot rotate and the tension rope 301 cannot be loosened. When the tension rope 301 needs to be loosened, the knob 201 is pulled upward, and the transmission ratchet 202 and the limit ratchet 203 will separate from each other, and the tension rope 301 can be stretched freely.

[0043] In this embodiment, the fixed axis 205 is printed on the 3D printed scoliosis orthosis body 1. During the production process of the orthosis body 1, four tension holes 302 are provided to facilitate the passage of the tension rope 301. A knob buckle 2 is provided in the middle part of the right side of the orthosis body 1 to control the tension rope 301 to tighten the orthosis body. The assembly is simple and not easy to fall off, and the fit is high.

[0044] In this embodiment, the knob 201, the transmission ratchet 202, the limit ratchet 203, the rope winding ratchet shaft 204 and the fixed shaft 205 are all made of plastic material, which is easy to process and mold, and is light in weight and does not add any additional burden.

[0045] In the above, by setting a knob buckle 2 on the 3D printed scoliosis orthosis body 1, the rope body is tightened and loosened in a rotating manner to achieve the effect of quickly tightening the orthosis body 1. The operation is simple and convenient, and the tedious operation of manually tying the straps is eliminated. At the same time, the knob buckle 2 adopts a unidirectional rotation method, which can achieve maximum adjustment and can better adjust the tightness of the orthosis, so that each adjustment of the tightness of the orthosis is not limited, ensuring that the orthosis is neither too loose nor too tight, and achieving the optimal correction effect.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
