Description

The present invention relates to a trunk brace that is worn around the lower back and restricts forward bending, backward bending, lateral bending, and rotation when it is difficult to hold the trunk due to compression fractures, spinal cord injuries, etc. .

In recent years, compression fractures of the thoracic or lumbar vertebrae in elderly people have been increasing. When treating this fracture, it is necessary to fix the fractured part by restricting forward and backward bending and lateral bending and rotation of the trunk so as not to place any burden on the fractured part in order to promote bone union. Fully custom-made trunk braces are common for this purpose, but they require a considerable amount of manufacturing time and cannot be provided from the early stages of treatment.

Patent Document 1 describes that the left and right chest braces and the left and right lumbar braces are connected via their respective side frames so that their vertical positions can be freely adjusted, and that the thoracic braces located above and the lumbar braces located below The anterior bending angle of each side frame can be adjusted freely, so a thoracolumbar trunk brace has been described that can be installed from the early stage of treatment and has excellent adaptability as if it were custom-made. ing.

The trunk orthosis 100 in Example 1 is worn from the chest to the lower back, and restricts forward bending, backward bending, and side bending rotation of the trunk so as not to place a burden on a compression fracture. Therefore, a left brace 1 is provided, which is attached to the left side of the trunk, and has a length that extends from the chest to the waist, and a right brace 2, which is attached to the right side of the trunk, and has a length that extends from the chest to the waist. The left brace 1 has a left brace main body 12 made of mesh-like cloth. This left brace main body 12 is made of a hard material (for example, synthetic resin or metal) and has a left upper and lower part 14 that vertically passes through the ventral end, and a left loop part 15 that loops (annularly) in the flank direction. A left annular frame 11 is provided. The left annular frame 11 is covered with a cloth to which a hook-and-loop fastener can be fixed, and is sewn into the left brace main body 12 and held there. The left loop portion 15 is displaced upward from the lower end of the ventral side toward the flank, extends upward at the flank, extends laterally from the lower part of the armpit toward the ventral side, and is looped in an annular shape. Thereby, since the left annular frame and the pelvis are detoured to avoid the pelvis, interference between the left annular frame and the pelvis can be prevented.

Similarly, the right brace 2 has a right brace main body 22 made of mesh-like cloth. This right brace main body 22 is made of a hard material (for example, synthetic resin or metal) and has a right upper and lower part 24 that vertically penetrates the ventral end, and a right loop part 25 that loops (annularly) in the flank direction. A right annular frame 21 is provided. The right annular frame 21 is covered with a cloth to which a hook-and-loop fastener can be fixed, and is sewn into the right brace main body 22 and held therein. The right loop portion 25 is displaced upward from the lower end of the ventral side toward the flank, extends upward at the flank, extends laterally from the lower part of the armpit toward the ventral side, and is looped in an annular shape. Thereby, since the detour is made to avoid the pelvis, it is possible to prevent the left annular frame 11 and the right annular frame 21 from interfering with the pelvis.

Further, in the first embodiment, the left loop portion 15 and the right loop portion 25 are displaced upward from the lower part of the armpit toward the ventral side. As a result, the left annular frame 11 and the right annular frame 21 can be prevented from interfering with the armpit since it can be detoured to avoid the armpit. The left annular frame 11 and the right annular frame 21 have an approximately trapezoidal outline shape as a whole.

That is, the left brace 1 has a left annular frame 11 made of a hard material and having an upper left lower portion 14 that vertically passes through the ventral end, and a left loop portion 15 that loops in the flank direction. Further, the right brace 2 has a right annular frame 21 made of a hard material and having an upper right lower part 24 passing through the ventral end in the vertical direction and a right loop part 25 looping in the flank direction. By having the left annular frame 11 and the right annular frame 21, the top part near the chest, the waist part, and the bottom part near the waist can be individually tightened, as will be described later. It is possible to realize a trunk brace for the thoracolumbar vertebrae that is highly adaptable to the body shape.

In addition, in Example 1, the left loop part 15 and the right loop part 25 were configured to be displaced upward from the lower part of the armpit toward the ventral side, but this is not necessarily limited to this, and changes can be made as appropriate. . For example, in the short type trunk orthosis described later, since it is worn from the lower end of the ribs to the lower back, it does not affect the armpit much. It may also have a configuration in which it extends straight.

The four front belts 3 (3A, 3B, 3C, 3D), which are ventral connecting parts, are folded back by the front belt fittings 7 (7A, 7B, 7C, 7D) and connected from the ventral end of the left brace 1 to the right brace. It extends in two directions. These four front belts 3 (3A, 3B, 3C, 3D) are each made of a hook-and-loop fastener, and are pulled individually and fixed to the right brace 2 to tighten the left brace 1 and the right brace 2 to fit the body shape. be able to. Therefore, the ventral surface of the right brace 2 has a structure to which a hook-and-loop fastener can be fixed. Similarly, the four back belts 4 (4A, 4B, 4C, 4D), which are the back side connecting parts, are folded back by the back belt metal fittings 8 (8A, 8B, 8C, 8D) to form the back end of the right brace 2. It extends from the left brace in one direction. These four back belts 4 (4A, 4B, 4C, 4D) are each made of hook-and-loop fasteners, and are pulled individually and fixed to the left brace 1 to form the left brace 1 and the right brace 2 on the back side. They can be tightened together. Therefore, the back surface of the left brace 1 has a structure to which a hook-and-loop fastener can be fixed.

By constructing the front belt 3 (3A, 3B, 3C, 3D), which is the ventral connection part, with a hook-and-loop fastener, it is possible to strongly tighten only the arbitrary front belt 3A, 3B, 3C, or 3D, and it can be adapted to the body shape. It can be fixed by In addition, by constructing the back belt 4 (4A, 4B, 4C, 4D), which is the back side connection part, with a hook-and-loop fastener, you can strongly tighten only the arbitrary back belt 4A, 4B, 4C, or 4D, and it will adjust to your body shape. Can be adapted and fixed.

In Example 1, the ventral side connecting portion and the back side connecting portion were configured with a hook-and-loop fastener, but the present invention is not necessarily limited to this and may be modified as appropriate. For example, it may be composed of one or more strings. When using one string, make multiple holes in the vertical direction at the left orthosis 1 end and right orthosis 2 end, and insert the laces into the holes alternately on the left, right, and left, just as you would pass a shoelace through. Just go through it. This allows the whole to be evenly and firmly connected.

A front patch 5 is provided from the ventral end of the left brace 1 toward the right brace 2 to hide the wearer's abdomen. Further, a back cloth 6 is provided from the back side end of the right brace 2 toward the left brace 1, so that the wearer's back can be hidden. In Example 1, the cloth 5 and the cloth 6 are mesh-like, but are not necessarily limited to this and can be changed as appropriate. For example, a non-mesh configuration may be used.

A frame insertion belt 9 (9A, 9B, 9C, 9D) is provided at the back end of the front belt 3 (3A, 3B, 3C, 3D) of the left brace 1 (see FIGS. 4 and 6). ), a left waist adjustment belt 13 made of a hook-and-loop fastener is provided at the back end of the third frame insertion belt 9C from the top, and the left waist adjustment belt 13 is pulled toward the back (see FIG. 4). By fixing it to the left brace main body 12 (see FIG. 5), only the waist portion can be tightened. At this time, since the left brace 1 includes the hard left annular frame 11, even if the left waist adjustment belt 13 is pulled toward the back and the waist is tightened, the top (above the waist) and bottom It is possible to realize a trunk brace for the thoracolumbar vertebrae that prevents tightening (below the waist) and is highly adaptable to the body shape.

Similarly, a right waist adjustment belt 23 made of a hook-and-loop fastener is provided near where the third front belt 3C from the top of the right brace 2 is fixed, and the right waist adjustment belt 23 can be pulled toward the back. By fixing it to the right brace main body 22 (see FIG. 2), only the waist portion can be tightened. At this time, since the right brace 2 includes the hard right annular frame 21, even if the right waist adjustment belt 23 is pulled toward the back and the waist is tightened, the top (above the waist) and bottom It is possible to realize a trunk brace for the thoracolumbar vertebrae that prevents tightening (below the waist) and is highly adaptable to the body shape.

In order to strongly tighten the waist region against the top and bottom regions, it is sufficient to strongly tighten the front belt 3C and back belt 4C against the front belts 3A, 3B, 3D and back belts 4A, 4B, 4D. By tightening the left waist adjustment belt 13 and the right waist adjustment belt 23 described above, the waist can be further tightened relative to the top and bottom. Thereby, it is possible to realize a trunk brace for the thoracolumbar vertebrae that is easily adapted to each person's body shape and has excellent adaptability.

In addition, the trunk brace 100 in Example 1 was a standard type that was worn from the chest to the lower back to limit the forward bending, backward bending, and side bending rotation of the trunk so as not to put a burden on the compression fracture site. However, it is not necessarily limited to this, and changes can be made as appropriate. For example, as described above, it may be a short-type trunk brace that is worn from the lower end of the ribs to the waist, or a long-type trunk brace that covers the entire chest from the waist. In short, a long type, standard type, or short type can be used depending on the symptoms, and any trunk orthosis that is worn mainly on the lower back can be used.

Further, although the number of front belts 3 is four, it is not necessarily limited to this and can be changed as appropriate. For example, in the case of a short type, since the top and bottom are short, a total of three pieces may be used, one each for the top, waist, and bottom. In addition, in the case of a long type, since the top and bottom are long, five or more may be used.

Further, in the first embodiment, the number of back belts 3 is four, but the number is not necessarily limited to this and can be changed as appropriate. For example, in the case of a short type, since the top and bottom are short, a total of three pieces may be used, one each for the top, waist, and bottom. In addition, in the case of a long type, since the top and bottom are long, five or more may be used.

In Example 1, since the front belt 3 (3A, 3B, 3C, 3D), which is the ventral connection part, is made of a hook-and-loop fastener, it is possible to strongly tighten any position such as the top part, waist part, or bottom part. It can be fixed to the right brace 2 at any position along the body shape. Similarly, the back belts 4 (4A, 4B, 4C, 4D), which are the back connecting parts, are made of hook-and-loop fasteners, so they can be tightened strongly at any position such as the top, waist, or bottom, and can adjust to your body shape. It can be fixed to the left brace 1 along the line. Thereby, it is possible to realize a trunk brace for the thoracolumbar vertebrae that is easily adapted to each person's body shape and has excellent adaptability.

Further, as described above, in the first embodiment, the left annular frame 11 and the right annular frame 21 are shaped to avoid the pelvis and armpit, but the shape is not necessarily limited to this and can be modified as appropriate. For example, the left annular frame 11 and the right annular frame 21 may be shaped to avoid only the pelvis.

Further, in the first embodiment, the left waist adjustment belt 13 and the right waist adjustment belt 23 are provided, but the present invention is not necessarily limited to this and can be modified as appropriate. For example, either the left waist adjustment belt 13 or the right waist adjustment belt 23 may be provided.

In this way, Example 1 is a trunk orthosis that is worn mainly on the lower back,
A left brace that is attached to the left side of the trunk,
A right brace attached to the right side of the trunk,
a ventral connector that tightens the left brace and the right brace on the ventral side;
a back side connector that tightens the left brace and the right brace on the back side,
The left brace has a left annular frame made of a hard material having an upper left lower part that vertically passes through the ventral end and a left loop part that loops in the flank direction,
The right orthosis is characterized by having a right annular frame made of a hard material having a right upper and lower part that passes through the ventral end in the vertical direction and a right loop part that loops in the flank direction. Therefore, it is possible to realize a trunk brace for the thoracolumbar vertebrae that is easily adapted to each person's body shape and has excellent adaptability.

Embodiment 2 of the present invention differs from Embodiment 1 in that a linear frame made of a hard material can be attached along the upper left lower portion of the left annular frame. Example 2 will be described with reference to FIG. 6. FIG. 6 is a diagram illustrating a linear frame of a trunk orthosis according to a second embodiment of the present invention.

The trunk brace 200 is worn by inserting a linear frame 31 between the frame insertion belt 9 (9A, 9B, 9C, 9D), which is the ventral end of the left brace 1, and the left brace main body 12. (See Figure 6). The linear frame 31 is made of a hard elastic material (eg, synthetic resin or metal). By attaching this linear frame 31 along the upper left lower portion 14 of the left annular frame 11, it is possible to strengthen the restrictions on forward bending, backward bending, lateral bending, or rotation.

In the first embodiment, the linear frame 31 can be attached to the ventral end of the left brace 1, but the present invention is not necessarily limited to this and can be modified as appropriate. For example, the linear frame 31 may be attachable to the ventral end of the right brace 2, or the linear frame 31 may be attachable to the ventral ends of the left brace 1 and the right brace 2. By attaching the linear frame 31 to the ventral ends of the left brace 1 and the right brace 2, the restrictions on forward bending, backward bending, lateral bending, or rotation can be further strengthened.

Furthermore, a linear frame 31 may be attached to the back end of the left orthosis 1 or the right orthosis 2 (see FIG. 7). Furthermore, a linear frame 31 may be attached to the back end portions of the left orthosis 1 and the right orthosis 2 (see FIG. 7). Thereby, restrictions on forward bending, backward bending, lateral bending, or rotation can be further strengthened.

In this way, in Example 2, the ventral end of the left brace, the ventral end of the right brace, the back end of the left brace, or the back end of the right brace is made of a hard material. By being able to attach the linear frame, it is possible to strengthen the restrictions on forward bending, backward bending, lateral bending, or rotation.

INDUSTRIAL APPLICABILITY The present invention can be widely used in the field of trunk braces that are worn around the lower back and restrict forward bending, backward bending, and side bending rotation of the trunk so as not to place stress on a compression fracture.
