Description

Waistline with 3D printing support bar

Technical Field

The invention relates to a waistline, in particular to a waistline with a 3D printing support strip.

Background

Lumbar diseases are often caused by the working requirements and poor sitting posture of modern people. Under physiological conditions, the lumbar vertebra protrudes to the front side, but the lumbar curvature is straightened or even protrudes to the rear side due to sedentary and poor sitting postures, so that the lumbar keyboard is protruded, expanded or separated, and meanwhile, the incidence rate of lumbar muscle strain can be increased due to long-term overload of lumbar muscles. When disc problems develop to the end stage, and there may even be a risk of paralysis, surgical treatment is often required. Therefore, in the early stage of the disease, in order to delay the further development of the disease and relieve symptoms, the treatment by means of rehabilitation therapy and rehabilitation aids is often required. Among them, the waist belt is convenient and easy to use, and can be used at any time in daily life, so fixing the lumbar vertebra by the waist fixing belt is one of the most common early treatment methods.

The waistline commonly seen on the market at present includes two types: one is a health care waistband, and the other is a medical apparatus-grade waist fixing band. Two types of waist fixing belts are common, one type is a simple soft waist fixing belt, and an elastic fabric is fixed on the waist in a surrounding way through snap buttons (magic tapes), so that the effects of limiting the movement and supporting of the lumbar vertebra are achieved; the other is to add a supporting strip on the back side based on the former type, thereby strengthening the supporting function.

The main function of waistline is fixing lumbar vertebra and supporting, patent CN211187689U discloses a multifunctional supporting type waist support, patent CN208541560U discloses an acupoint stimulating waistline, and patent CN2922837Y discloses a health-care waistline.

The existing products tend to be mature and stable in the aspect of fixation, but are still insufficient in the aspect of support. Due to the individual difference, the waistline produced in batch in the traditional method is low in cost and small in size, and cannot be completely matched with a patient in the length and the curvature of the lumbar vertebra, so that the expected effect is difficult to achieve; in addition, the curvature of the traditional waistline of the same model is fixed, so that the traditional waistline cannot be completely matched with the pathological curvature of a user, and cannot be gradually corrected.

Disclosure of Invention

The invention aims to solve the problem that the traditional waistline cannot be matched with a patient in a personalized manner, and provides the waistline with the 3D printing support strip, and the waistline can be adjusted in real time according to the change of the illness state by replacing the 3D printing support strip, so that the aim of gradually correcting the illness state is fulfilled.

The purpose of the invention is realized by the following technical scheme:

the utility model provides a waistline with 3D prints support bar, includes the waistline body, the waistline body includes lumbosacral portion and establishes the waistline portion in lumbosacral portion both sides, the waistline portion that lumbosacral portion is wider in both sides, the tip of waistline portion is equipped with can dismantle the connecting piece, be equipped with the slash pocket that just length difference that a plurality of symmetries set up in the lumbosacral portion, be equipped with the stereoplasm support bar that can take out in the slash pocket, the support bar is printed by 3D and is obtained.

According to the invention, the hard support strips with different lengths are manufactured by 3D printing, the length and the width of each support strip are adjusted according to the actually required hardness, the individualized requirements of different patients are perfectly matched, and the support strip can be adjusted in real time according to the change of the state of an illness, so that the purpose of gradual correction is achieved.

Further, the supporting strip is made of nylon through 3D printing.

Further, when the support strip is manufactured by 3D printing, the specific method comprises the following steps: the method comprises the steps of carrying out CT scanning and body surface scanning on a user to obtain body data for modeling, respectively designing the length and the width of a supporting strip according to the length and the width of the back of a lumbar vertebra, designing the curvature under the guidance of a doctor, and outputting an STL file for printing after the design is finished.

Further, the length and width design of the supporting bars is determined according to the following method:

the height is 150-165cm, and the width of the support strip is 12 mm; the height is 165-180cm, and the width of the support strip is 14 mm; the height is above 180cm, and the width of the support bar is 15 mm;

the projection length of the coronal plane of the support bar with the longest middle is the distance from the lower edge of the vertebral body of lumbar vertebra L5 to the upper edge of the vertebral body of T12, and the lengths of other support bars positioned at the two sides of the support bar with the longest middle are sequentially decreased by 20 mm.

Further, the waistline body is made of elastic fabric.

Furthermore, the lumbosacral part is made of breathable cloth, the inserting bags are sewn on the lumbosacral part and connected through elastic fabrics, and certain pressure can be generated when the inserting bags are bound on the waist of a user, so that the inserting bags help to fix and prevent displacement.

Furthermore, two elastic reinforcing belts are respectively arranged on two sides of the lumbosacral part to increase pressure.

Furthermore, 4-8 inserting bags are arranged.

Furthermore, the supporting strips are long strips with radian and are gradually shortened from the middle to two sides.

Furthermore, the detachable connecting piece is a snap button or a magic tape, and the waist is fixed on the waist by mutually attaching the detachable connecting piece to the abdomen of the user.

The invention has the following beneficial effects:

the waist can be worn at any time in daily life and is hardly limited by the use scene; the double functions of supporting and correcting can be achieved simultaneously, and the design method based on the iconography avoids discomfort caused by overlarge correcting force and incapability of generating a treatment effect caused by undersize supporting strip curvature; in addition, the personalized 3D printing design can relieve discomfort and pain caused by the non-equipped shape, prolong the tolerable time of the user and enhance the treatment effect.
