Technical Field

[0001] The utility model relates to the technical field of rehabilitation braces, in particular to a brace with a 3D printed finger plate. Background Art

[0002] As an orthosis, the fingerboard has the function of preventing and correcting contracture. It is currently widely used in the treatment of hemiplegic upper limbs in muscle spasms. Studies have shown that the use of the fingerboard can increase the elasticity of the wrist and hand flexor muscles and their surrounding tissues, thereby effectively reducing spasms, increasing wrist-hand ROM, and improving hand function.

[0003] When using a traditional fingerboard, the patient's fingers are often directly tied to the outer wall of the fingerboard, relying on the shape of the fingerboard itself to prevent the patient's fingers from flexing and spasming. However, when using a traditional fingerboard, there is only one way to statically fix the hand, which cannot achieve more training effects. Therefore, the scope of application of the equipment is limited and the effect of exercise rehabilitation is not good enough. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the present invention provides a 3D printed fingerboard wearing brace, which has the advantages of multiple exercise methods and easy use, and solves the problems raised by the above-mentioned background technology.

[0005] The utility model provides the following technical solution: a wearing brace for a 3D printed finger plate, comprising a base, an inner cavity of the base providing a movable groove, the inner cavity of the movable groove being fixedly equipped with a fixed plate, the inner cavity of the fixed plate being threadedly connected to a driving screw, the inner cavity of the driving screw being rotatably connected to a push rod, the inner cavity of the movable groove being movably sleeved with a movable plate, the outer wall of the movable plate being rotatably connected to a support wheel, the inner cavity of the base providing a movable groove, the inner cavity of the movable groove being movably sleeved with a movable block, the outer wall of the movable block being fixedly equipped with a finger plate body, and the outer wall of the finger plate body being fixedly equipped with an elastic band.

[0006] As a preferred technical solution of the present invention: an inner wall of the fixing plate is provided with an internal thread, and the inner wall thread of the fixing plate is meshed with the outer wall thread of the driving screw.

[0007] As a preferred technical solution of the present invention: the shape of the outer wall of the movable plate matches the shape and size of the inner wall of the movable groove, and the outer wall of the supporting wheel is installed with a rubber anti-slip ring.

[0008] As a preferred technical solution of the present invention: the outer wall of the push rod away from the driving screw is in contact with the outer wall of the movable plate, and a rubber anti-slip pad is installed on the outer wall of the push rod close to the movable plate.

[0009] As a preferred technical solution of the present invention: the shape of the outer wall of the moving block matches the shape and size of the outer wall of the movable groove, and the pushing rod and the moving plate are both made of ABS plastic.

[0010] As a preferred technical solution of the present invention: there are two movable plates, and the two movable plates are respectively installed in the inner cavities on both sides of the base.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The 3D printed finger brace has a base provided below the finger brace and a movable block provided at the bottom of the finger brace. The fingers are bound to the outer wall of the finger brace. The finger brace is pushed by the arm to move, so that the movable block can move back and forth in the inner cavity of the base, thereby exercising the patient's arm. The device can not only fix the fingers but also exercise the arm strength.

[0013] 2. The 3D printed finger plate wearing brace has a fixing plate arranged in the inner cavity of the movable groove, and a driving screw arranged in the inner cavity of the fixing plate. Under the action of the driving screw, the movable plate is pushed to move, so that the outer wall of the support wheel is more closely fitted to the outer wall of the movable block, thereby changing the friction between the support wheel and the outer wall of the movable block. At this time, the force required to push the movable block to move will change, so that when exercising the arm, it can be adjusted according to the patient's arm strength, making the device more suitable for users with different strengths.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1 - Figure 5 A 3D printed finger plate wearing brace includes a base 1, a movable groove 2 is opened in the inner cavity of the base 1, a fixed plate 3 is fixedly assembled in the inner cavity of the movable groove 2, a driving screw 4 is threadedly connected to the inner cavity of the fixed plate 3, a push rod 5 is rotatably connected to the inner cavity of the driving screw 4, a movable plate 6 is movably sleeved in the inner cavity of the movable groove 2, and a support wheel 7 is rotatably connected to the outer wall of the movable plate 6, a movable groove 8 is opened in the inner cavity of the base 1, a movable block 10 is movably sleeved in the inner cavity of the movable groove 8, a finger plate body 9 is fixedly assembled on the outer wall of the finger plate body 9, and an elastic band 11 is fixedly assembled on the outer wall of the finger plate body 9.

[0022] By means of the finger plate 9 provided on the top of the base 1 and the elastic band 11 provided on the outer wall of the finger plate 9, the elastic band 11 can bind the patient's hand to the outer wall of the finger plate 9, thereby achieving the fixation of the fingers. After the fingers are fixed, the outer wall of the finger plate 9 can prevent the fingers from flexing and contracting, so that the flexed and spasmodic joints can remain in a straight state.

[0023] In a preferred embodiment, an inner wall of the fixing plate 3 is provided with an internal thread, and the inner wall thread of the fixing plate 3 and the outer wall thread of the driving screw 4 are meshed with each other.

[0024] By setting a fixed plate 3 in the inner cavity of the movable groove 2 and a driving screw 4 in the inner cavity of the fixed plate 3, the movable plate 6 is pushed to move under the action of the driving screw 4, so that the outer wall of the support wheel 7 fits more closely to the outer wall of the movable block 10, thereby increasing the friction between the outer wall of the movable block 10.

[0025] In a preferred embodiment, the shape of the outer wall of the movable plate 6 matches the shape and size of the inner wall of the movable groove 2 , and the outer wall of the supporting wheel 7 is installed with a rubber anti-slip ring.

[0026] By arranging the fixing plate 3 and the driving screw 4 in the inner cavity of the movable groove 2, the movable plate 6 can move forward along the inner wall of the movable groove 2 under the action of the driving screw 4, so that the supporting wheel 7 on the outer wall of the movable plate 6 approaches the outer wall of the movable block 10, thereby increasing the friction between the movable block 10, so that greater force is required when it is necessary to push the movable block 10 to move.

[0027] In a preferred embodiment, the outer wall of the push rod 5 away from the driving screw 4 contacts the outer wall of the movable plate 6 , and a rubber anti-slip pad is installed on the outer wall of the push rod 5 close to the movable plate 6 .

[0028] By rotating the push rod 5 connected to the outer wall of the driving screw 4, when the driving screw 4 rotates, the outer wall of the other end of the push rod 5 fits against the outer wall of the movable plate 6. At this time, when the driving screw 4 rotates, the push rod 5 will not rotate due to the friction force of the movable plate 6, and will move forward under the push of the driving screw 4, thereby pushing the movement of the movable plate 6, so that the outer wall of the support wheel 7 can approach the outer wall of the movable block 10.

[0029] In a preferred embodiment, the shape of the outer wall of the moving block 10 matches the shape and size of the outer wall of the movable groove 8 , and the push rod 5 and the moving plate 6 are both made of ABS plastic.

[0030] By opening a movable groove 8 in the inner cavity of the base 1, the finger plate 9 and the moving block 10 are installed in the inner cavity of the movable groove 8. At this time, the finger plate 9 not only fixes the hand, but also can slide the finger plate 9 along the inner wall of the movable groove 8, thereby realizing arm exercise and obtaining better exercise function.

[0031] In a preferred embodiment, there are two movable plates 6 , and the two movable plates 6 are respectively installed in the inner cavities on both sides of the base 1 .

[0032] By installing two movable plates 6 on both sides of the inner cavity of the base 1, the movable block 10 can be pressed from both sides under the action of the movable plates 6 on both sides, so that when the base 1 and the finger plate body 9 are used for exercise, the movable plates 6 on both sides can be adjusted so that the force required to push the finger plate body 9 can be adjusted, thereby better exercising the patient's arm.

[0033] Working principle: During the use of the above-mentioned device, when the device is needed to fix the hand, the hand is placed on the outer wall of the finger-dividing plate 9, and the fingers are passed through the inner cavity of the elastic band 11. The fingers are fixed under the action of the elastic band 11. At this time, the flexion spasm of the finger joints can be avoided well under the action of the finger-dividing plate 9 and the elastic band 11. After the fingers are fixed, the finger-dividing plate 9 is pushed to move back and forth along the outer wall of the base 1 to exercise the patient's arm. By adjusting the driving screws 4 on both sides, the pressure of the outer wall of the support wheel 7 on the moving block 10 is adjusted. When the outer wall of the support wheel 7 is closer to the outer wall of the moving block 10, the thrust required to push the finger-dividing plate 9 is greater. The position of the driving screw 4 can be adjusted according to the patient's arm strength, thereby gradually exercising the patient's arm strength, so that the device can not only prevent flexion spasm of the finger joints, but also exercise the patient's arm strength.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
