Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 For example, the present invention is applied to a wrist joint or the like for supporting a hand / forearm fracture after casting and for preventing / treating tendinitis around the elbow / wrist and muscle inflammation. It relates to a knot orthosis.

[0002]

[Prior art]

 When performing racket sports such as tennis, excessive gripping or bending of the wrist often causes injury to the wrist or elbow.

[0003] For example, the impact received during a tennis shot or service is first transmitted to the wrist that directly contacts the racket, and if a large impact is repeatedly applied to the wrist without the ball hitting the sweet spot of the racket, the hand Causes joint pain.

[0004] The pathology of this wrist joint pain includes tendon diseases such as radial extensor tendonitis of the thumb, extensor carpi extensor tendonitis of the ulnar side, TFCC disorders, disorders around the bean bone, and central dorsal bone. Extensor tendonitis, inferior necrosis of the lunate, carpal instability, etc.

[0005] In order to prevent such wrist pain, a wrist orthosis for protecting the wrist has been conventionally proposed.

[0006] As this type of wrist orthosis, for example, as described in Japanese Patent Application Laid-Open No. 10-295870, the index finger, ring finger, middle finger base and the rear part of the wrist are fixed with a band, and between them. An elastic body is known.

[0007]

[Problems to be solved by the invention]

 However, the wrist orthosis described in the above publication mainly restricts the wrist flexion movement of the wrist, and cannot effectively suppress the dorsiflexion movement, the flexion movement and the supination movement of the wrist. Therefore, for example, movements such as lowering the head of the racket or kneading the wrists for more spin cannot be suppressed.

[0008] Even when restricting the palmar flexion movement of the wrist, the wrist is relatively easily bent because the purpose is to simply reduce the strain on the muscle using an elastic body.

For this reason, stress is easily applied, and there is a problem that it is not very useful for prevention and treatment of wrist pain.

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

Embodiment 1 FIG. 1 is a partially cutaway perspective view showing a configuration of a wrist orthosis according to a first embodiment of the present invention. FIGS. 2 to 7 show a method of attaching the wrist orthosis to a wrist or the like. It is an explanatory view for explaining.

As shown in FIGS. 1, 6, and 7, the wrist orthosis 1 according to the first embodiment mainly includes a wrist joint for the upper limb (the right side in the first embodiment) having a racket, for example. In order to constrain the movement of the arm, it is used by being attached to the protected area including the wrist at the end of the upper limb and its vicinity, and is wound around the wrist, etc. to cover the wrist, etc. Elongated flat plate-like members (suppression members) 3, 3 having predetermined rigidity attached to the outer surface side of the covering 2 to be applied, and fixed to the outer surface side of the covering 2 to which the palm side is applied. A long flat plate member (suppression member) 4, 4 having a predetermined rigidity, a band member 5 for fixing the flat plate member 4, 4, and a state where the band member 5 is hooked on a little finger and pulled in a pronation direction. A string that is spirally wound and fixed from above the covering 2 And a wrap member 6.

The cover 2 has a cover main body 21 whose inner surface is applied to a wrist joint and the like, and insertion holes 22 a, 22 b, and 22 c provided at an upper central portion for inserting and locking an index finger, a middle finger, and a ring finger. And fixing tapes 23, 23, 23 provided on one side for fixing the covering body 21 to a wrist joint or the like.

The cover body 21 has a substantially convex shape having a central portion 211 whose inner surface is mainly applied to the back of the hand such as a wrist joint, and sleeves 212 on both sides whose inner surfaces are mainly applied to the forearm side. A buffer layer 21a having an outer shape and having a cushioning property applied to the inner wrist joint and the like, and a loop layer 21b made of a pile fabric provided with a large number of minute wrinkles on the outer side are bonded to each other. ing.

When a member having a hook layer provided with a correspondingly large number of minute hook-like projections is pressed against the loop layer 21b, the loops of the loop layer 21b and the hook-like projections of the hook layer are brought into contact with each other. The two layers are connected by being hooked, and the two layers are peeled off by being pulled with a force of a predetermined strength or more. Thus, the loop layer 21b and the hook layer function as a detachable hook-and-loop fastener (touch-close type fastener).

Further, by changing the bonding portion between the loop layer 21b and the hook layer, for example, the winding strength is adjusted as described later.

One end of each fixing tape 23 is adhered to a side end of one sleeve portion 212, and a hook layer 231 corresponding to the loop layer 21 b is provided on the back side. At the time of mounting, the hook layer 231 is pressed against the outer side loop layer 21b at the side end of the other sleeve portion 212, so that the two are adhered, and the cover 2 is mounted in a state where the wrist joint or the like is tightened. .

Here, by adjusting the bonding position of the hook layer 231 to the loop layer 21 b, the tightening force is adjusted according to the individual difference in the size of the hand and the restraining force required for the movement of the wrist joint or the like. Is done.

Each of the plate-like members 3 has a core material 31 made of, for example, steel and is covered with two coating layers 32, 32. It is placed on the back of the hand while being bridged over the hand joint, and the dorsi-flexion movement of bending the wrist joint from the palm side to the back side, or bending the wrist joint from the back side to the palm side. Suppresses flexing movements.

The flat member 3 is bent at a predetermined angle or remains linear depending on the bent or non-bent form of the wrist or the like to be fixed.

Each of the plate-shaped members 4 has a core material 41 made of, for example, a synthetic resin covered with two covering layers, and is arranged on the palm side such that the lengthwise direction substantially matches the hand length direction. It reduces palm flexion and dorsiflexion.

The plate-like member 4 is also bent at a predetermined angle corresponding to the plate-like member 3 or remains linear.

Of the two covering layers, the covering layer facing the palm when worn is a hook layer 42a on the front side corresponding to the loop layer 21b. The coating layer on the side where the band member 5 is wound at the time of mounting is a loop layer 42b.

The band member 5 is wound from above the plate members 4, 4 to fix the plate members 4, 4 to the hand from above the cover 2.

The band member 5 is provided with a hook layer 51a corresponding to the loop layer 42b on the side that comes into contact with the flat member 4 at the time of mounting, and has a hook layer 51 on one end on the opposite side (outer surface side). A loop layer 51b corresponding to 51a is provided.

The strap member 6 includes a locking portion 61 provided with an insertion hole 61 a for inserting and locking the little finger, and a belt 62. The strap member 6 is fixed in a state where the little finger is pulled toward the thumb. In addition, the supination movement of returning the palm from downward to upward is suppressed, and the cover 2 is tightened from the outside to fix the flat members 3 and 4 with a predetermined tightening force.

In addition, this tightening also suppresses the angulation movement of bending the wrist from the thumb side to the little finger side. In addition, each movable range of the movement of the wrist joint is limited according to the degree of adjustment of the tightening force.

The belt 62 is provided with a hook layer 62a corresponding to the loop layer 21b on the side that comes into contact with the cover 2 and the like when worn.

When mounting the wrist orthosis 1, first, the index finger, the middle finger, and the ring finger are inserted into the insertion holes 22 a, 22 b, and 22 c of the cover 2, respectively, as shown in FIGS. From the side (back side) so that it is locked by the crotch of the finger, the buffer layer 21a of the central part 211 of the cover body 21 is in close contact with the back of the hand, and the sleeves 212, 212 are With the side ends of the sleeves 212 and 212 pulled by a predetermined force, the fixing tapes 23 are pressed against the ends of the corresponding sleeves 212 so that the loop layers 21b and the hook layers are turned. The cover 2 is attached to the wrist or the like so as not to disturb the grip.

Next, as shown in FIGS. 4 and 5, the flat members 4 and 4 were applied to the palm side of the cover 2 and fixed by the adhesive force between the loop layer 21 b and the hook layer 42 a. Thereafter, the band member 5 is wound from above, and stopped by the adhesive force between the loop layer 21b, the loop layer 42b, and the loop layer 51b and the hook layer 51a, and the respective flat members 4 are fixed.

Next, as shown in FIG. 6 and FIG. 7, the little finger is inserted into the insertion hole 61 a of the strap member 6 from the inner surface side (back surface side), and is locked by the crotch portion of the finger. The belt 62 is spirally wound around the back of the hand, the palm of the hand and the base of the hand while being pulled with a predetermined force. At this time, the strap member 6 is fixed to the cover 2 by the adhesive force between the loop layer 21b and the hook layer 62a. As a result, the wrist or the like is tightened by the strap member 6 from above the cover 2 with a predetermined force.

Here, the cover members 2 are fixed to the wrist joint or the like by the fixing tape 23, and the cover members 2 are fastened by the band member 5 and the strap member 6 from above. Through the wrist joint at the back of the hand.

The flat members 4, 4 are tightened from above by a band member 5, and further tightened from above by a strap member 6, so that the flat members 4, 4 are located at the palm joint side via the cover 2. Pressed.

Thus, the wrist is substantially fixed in a predetermined bent state or a non-bent state according to the shape of the flat members 3 and 4. 4 prevents this dorsiflexion by suppressing the movement of the wrist joint due to its rigidity. It also resists palmar flexion of the hand joint. Further, since the wrist joint is particularly held down by the strap member 6, the wrist joint also resists the flexion movement and the like.

The strap member 6 is fixed in a state where the little finger is pulled toward the thumb, thereby suppressing the supination.

Further, the flat members 3 and 4 are tightened from outside by a predetermined tightening force, and the flat members 3 and 4 are further pressed against the wrist or the like to be fixed. It contributes to the suppression of flexion, shaking and supination.

The strength of pressing the flat member 3 against the wrist or the like via the cover 2 and fixing the same is determined by the bonding of the hook layer 231 to the loop layer 21 b when the fixing tape 23 is bonded to the cover 2. The position, the adhesion position of the loop layer 51b to the hook layer 51a when the band member 5 is wound, and the adhesion position of the hook layer 62a to the loop layer 21b and the like (the winding route of the belt 62) when the strap member 6 is wound. It can be adjusted freely by choosing it properly.

The strength of pressing the flat plate member 4 against the wrist joint or the like depends on the bonding position of the loop layer 51 b to the hook layer 51 a when the band member 5 is wound, and the hook when the strap member 6 is wound. It can be adjusted freely by appropriately selecting the bonding position of the layer 62a to the loop layer 21b and the like (the winding path of the belt 62).

In this way, dorsiflexion, palmar flexion, extensor flexion, and supination at the wrist can be suppressed with desired strength.

In Embodiment 1, the dorsiflexion, palm flexion, extensor flexion, and supination are slightly adjusted to allow for dorsiflexion, wrist flexion, and supination.

Using the wrist orthosis 1 according to the first embodiment to treat, for example, an intermediate tennis player, a number of improved examples were obtained.

[0050] Treatment was attempted for cases in which there was movement pain and tenderness on the ulnar side, and there was pain each time a shot was taken, and depending on the day, the pain persisted even after the end of tennis.

For example, a person whose wrist instability was recognized on an X-ray photograph was asked to play while wearing the wrist orthosis 1. As a result, although the movement of the wrist joint seems to be restricted, the pain has been resolved and the stroke and serve can be hit with confidence.

[0052] A wrist joint brace 1 was used by a tennis player who had both forehands and backhands and who complained of right hand joint pain. The team confirmed that the supporter 1 would not restrict the tennis movement of advanced players, and worked to improve the form. As a result, it improved in three months.

[0053] There were many cases where the condition was reduced in about one month.

As described above, according to the first embodiment, the flat members 3 and 4 are applied to the wrist or the like from above the cover 2 at the time of mounting, and the fixing tape 23 and the band member 5 are attached. By being tightened from above using the strap member 6, the strap member 6 is pressed against the wrist via the cover 2, and the strap member 6 is fixed in a state where the little finger is pulled in a pronation direction. Therefore, dorsiflexion, palm flexion, extensor flexion, and supination of the wrist can be suppressed.

As a result, the movement of the wrist joint that may cause a failure can be reliably suppressed, and the above-described failure can be prevented. In addition, even if the disorder has already occurred, the stress that causes pain can be prevented, so that treatment can be performed while continuing exercise. In addition, it can help, for example, correct misuse of the upper limb and improve it to the correct form.

The strength for pressing and fixing the flat members 3 and 4 to the wrist or the like via the cover 2 is determined by a loop corresponding to the hook layer (the hook layer 231, the hook layer 51 a, and the hook layer 62 a). It can be freely adjusted by appropriately selecting the bonding position with the layers (the loop layer 21b and the loop layer 51b), so that the dorsiflexion movement, the palmar movement, the extensor movement, and the supination movement in the wrist joint are possible. Can be suppressed with a desired strength.

Further, since the strap member 6 is spirally wound around the covering 2 and the flat members 3 and 4 around the wrist or the like, the covering member 2 and the flat members 3 and 4 can be securely fixed. And the tightening force can be adjusted by the strap member 6.

Further, since the flat member 4 is detachably adhered to the cover 2 by the hook-and-loop fastener, for example, the mounting position can be adjusted so as not to interfere with the grip.

Further, the index finger, the middle finger, and the ring finger are inserted into the insertion holes 22a, 22b, and 22c and fixed to the cover 2, and the little finger is inserted into the insertion hole 61a and fixed to the strap member 6. It can be attached to a car and can be prevented from falling off or slipping off even after it is attached.

As described above, the embodiment of the present invention has been described in detail, but the specific configuration is not limited to this embodiment.

For example, in the above-described embodiment, one of the hook-and-loop fasteners is the hook layer 231, the hook layer 42 a, the hook layer 51 a, and the hook layer 62 a having a large number of hook-shaped protrusions. Is also good.

Further, a hook layer may be provided on the outer surface of the fixing tape 23, the outer surface of the flat member 3, the outer surface of the band member 5, and the like. Further, the strap member 6 may be provided with a hook layer only at the end of the belt 62.

The wrist joint brace may be mounted so that the flat member is applied to, for example, a portion of the wrist joint on the side of the little finger.

Alternatively, the strap member 6 may be attached to the thumb instead of the little finger and turned toward the palm to pull in the pronation direction.
