Abstract
Description
Technical Field
[0001] This utility model belongs to the field of rehabilitation equipment technology, and specifically relates to a shoulder abduction brace. Background Technology
[0002] Rotator cuff injuries, especially large tears in the rotator cuff tissue, require patients to wear a shoulder abduction pack after surgery to immobilize shoulder abduction and promote rapid healing of the internal sutured tendons. However, existing shoulder abduction packs are large and bulky, and while immobilizing shoulder abduction, they also restrict the movement of the elbow, wrist, and hand, causing some patients to experience stiffness in their wrist and elbow joints after removing the abduction pack.
[0003] Therefore, there is an urgent need for a lightweight, flexible shoulder abduction brace that provides good shoulder braking and does not affect the movement of the elbow, wrist, and hand. Utility Model Content

[0023] Example 1:
[0024] In this embodiment, a shoulder abduction brace, such as Figure 1As shown, it includes a torso fixation plate 1, an upper arm fixation plate 2, and an angle adjustment device. Specifically, the torso fixation plate 1 is provided with a first fixing strap 3, the upper arm fixation plate 2 is provided with a second fixing strap 4, and the angle adjustment device is connected between the torso fixation plate 1 and the upper arm fixation plate 2 to adjust the outward angle of the upper arm fixation plate 2.
[0025] With this structure, the torso fixation plate 1 is fixed to one side of the torso below the patient's armpit by the first fixing strap 3, and the upper arm is fixed to the upper arm fixation plate 2 by the second fixing strap 4. The angle adjustment device makes the torso fixation plate 1 and the upper arm fixation plate 2 form a stable angle, thereby controlling the abduction angle of the upper arm fixation plate 2, keeping the shoulder at a fixed abduction angle, resulting in better braking effect. The wrist and elbow are not restricted and can move flexibly without joint stiffness. The overall structure is lightweight and flexible, reducing the patient's load and making this utility model more practical.
[0026] As one specific implementation method of this embodiment, such as Figure 1 As shown, the angle adjustment device includes two adjustment components 5 with the same structure. The two adjustment components 5 are connected in parallel and spaced apart between the torso fixing plate 1 and the upper arm fixing plate 2. Two screws 6 are connected between the two adjustment components 5. The ends of the screws 6 are screwed with locking nuts 7. The outward angle of the adjustment components 5 is locked by the locking nuts 7, so as to achieve the purpose of angle adjustment.
[0027] Specifically, such as Figure 1 As shown, the adjustment assembly 5 includes a first fixed plate 8, a movable plate 9, and a second fixed plate 10. The first fixed plate 8 is fixedly connected to the top outer side of the torso fixed plate 1, and the second fixed plate 10 is fixedly connected to the top inner side of the upper arm fixed plate 2. The first fixed plate 8 has a first elongated arc hole 11, the second fixed plate 10 has a second elongated arc hole 12, and the movable plate 9 has a third elongated arc hole 13. One of the screws 6 passes through the first elongated arc hole 11 and the third elongated arc hole 13 of the two adjustment assemblies 5. The arc hole 13 is screwed into the locking nut 7. Another screw 6 passes through the second long arc hole 12 and the third long arc hole 13 of the two adjusting components 5 and is screwed into the locking nut 7. With this arrangement, the relative positions of the first fixed plate 8, the movable plate 9 and the second fixed plate 10 are adjusted so that the first long arc hole 11 and the third long arc hole 13 overlap or stagger, and the second long arc hole 12 and the third long arc hole 13 overlap or stagger, thereby achieving the purpose of changing the outward angle of the adjusting component 5.
[0028] In this embodiment, as Figure 1As shown, the first long arc hole 11, the second long arc hole 12, and the third long arc hole 13 are all identical in shape and size. The central arc angle of the first long arc hole 11, the second long arc hole 12, and the third long arc hole 13 is 30°. When the first long arc hole 11 and the third long arc hole 13 are offset to a certain extent or completely overlap, and when the second long arc hole 12 and the third long arc hole 13 are offset to a certain extent or completely overlap, the adjustment component 5 can be adjusted and fixed at a stable outward angle of 30°, 60°, and 90°.
[0029] In this embodiment, there are two first fixing straps 3. The two first fixing straps 3 are fixedly connected to the torso fixing plate 1, one above the other, so that both the upper and lower ends of the torso fixing plate 1 can fit tightly to the torso and the fixation is more secure. As an optimization, both the first fixing straps 3 and the second fixing straps 4 are provided with adjustment buckles 15. The length of the first fixing straps 3 and the second fixing straps 4 can be adjusted by the adjustment buckles 15, which improves the binding stability and can be suitable for patients with different body types.
[0030] In this embodiment, as Figure 1 As shown, both the torso fixing plate 1 and the upper arm fixing plate 2 are curved panels, which makes the torso fixing plate 1 fit the side of the torso more closely, and the upper arm sinks into the upper arm fixing plate 2 and is limited by the two side walls of the curved panel, thus restricting the back-and-forth swing of the upper arm.
[0031] In this embodiment, a sponge pad 14 is also included. The sponge pad 14 is adhered to the outer surfaces of the torso fixing plate 1 and the upper arm fixing plate 2. The sponge pad 14 enables the torso fixing plate 1 and the upper arm fixing plate 2 to form a flexible contact with the torso and upper arm, avoiding discomfort caused by hard contact and improving comfort.
[0032] In this embodiment, the trunk fixation plate 1 and the upper arm fixation plate 2 are lightweight metal plates or rigid plastic plates, which have sufficient structural strength and are lighter in weight, thus avoiding excessive weight burden on the patient.
[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
