Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and specifically relates to a fixing brace after rotator cuff surgery. Background Art

[0002] The rotator cuff, also known as the rotary cuff, is a group of tendon complexes that surround the humeral head. In front of the humeral head is the subscapularis tendon, above is the supraspinatus tendon, and behind are the infraspinatus tendon and the teres minor tendon. The movement of these tendons causes internal rotation, external rotation, and abduction of the shoulder joint. More importantly, these tendons stabilize the humeral head on the glenoid fossa, playing an extremely important role in maintaining the stability of the shoulder joint and shoulder joint activities. In the initial stage of rotator cuff injury rehabilitation training, a brace is required to keep the shoulder joint in a slightly abducted position. On the first day after surgery, active movements of the elbow, wrist, and finger joints are started, and the time and frequency of activities are gradually increased. Passive shoulder joint activities start on the second day after surgery. Within 4 weeks after surgery, active shoulder joint activities are prohibited. After 4 weeks, the range of passive shoulder joint activities can be gradually increased, as long as it does not cause pain. It is not certain how long it takes for a rotator cuff injury to fully recover, but as long as the rehabilitation training method is correct, the rotator cuff injury of the patient can be solved. The support angle of the traditional rotator cuff suspension brace is non-adjustable and the position is fixed, so simple rehabilitation activities cannot be carried out. Over time, it is easy to cause discomfort and pain to the patient. Moreover, due to the lack of proper support for the elbow, the elbow is easily suspended, causing joint soreness and deltoid discomfort, thus slowing down the patient's rehabilitation progress. For this reason, we propose a fixing brace after rotator cuff surgery to solve the above problems. Summary of the Invention

Detailed implementation manners

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figure 1-8, an embodiment provided by the present invention: a fixation brace after rotator cuff surgery, including two groups of protective shells 1 and a first magic tape 2. The first magic tape 2 is movably connected to the outer sides of the two groups of protective shells 1. A fixing plate 3 is fixedly connected to the right side of the protective shell 1. The top of the fixing plate 3 is connected to a first movable plate 4. A first rotating shaft 5 is inserted at the connection point between the fixing plate 3 and the first movable plate 4. The first movable plate 4 is rotatably connected to the fixing plate 3 through the first rotating shaft 5. The right end of the first movable plate 4 is connected to a second movable plate 6. A support assembly 7 is arranged between the first movable plate 4 and the fixing plate 3; the support assembly 7 includes a first fixing block 71, a connecting rod 72, a plug pin 73, a connection groove 74 and a linkage assembly 75. Two groups of first fixing blocks 71 are fixedly installed at the bottom of the first movable plate 4. The inner sides of the two groups of first fixing blocks 71 are rotatably connected to a connecting rod 72. The plug pin 73 is inserted into the interiors of the first fixing block 71 and the connecting rod 72. A connection groove 74 is formed on the surface of the fixing plate 3. The linkage assembly 75 is arranged inside the connection groove 74; when the patient's limb is placed at the first movable plate 4, when the limb is lifted, first insert the plug pin 73 into the connection holes of the first fixing block 71 and the connecting rod 72, and then drive the connecting rod 72 to move upward along the connection groove 74 through the first rotating shaft 5 by the first movable plate 4, so that the included angle between the first movable plate 4 and the fixing plate 3 is adjusted to a suitable position.

[0019] Through the setting of the support assembly 7 of the present device, the problems of the traditional rotator cuff suspension brace are solved, such as the support angle is not adjustable, the position is fixed, simple rehabilitation activities cannot be carried out, and due to the lack of proper support for the elbow, it is easy to cause the elbow to hang in the air, resulting in joint soreness and deltoid discomfort, thereby slowing down the patient's rehabilitation progress.

[0020] Furthermore, fixing components 8 are arranged on the surfaces of the first movable plate 4 and the second movable plate 6. The fixing components 8 include positioning plates 81, second fixing blocks 82, second magic tapes 83 and adjusting components 84. Two groups of positioning plates 81 are connected to the front and rear sides of the surfaces of the first movable plate 4 and the second movable plate 6. The outer surfaces of the positioning plates 81 are fixedly connected to second fixing blocks 82. The outer sides of the second fixing blocks 82 are connected to second magic tapes 83. The adjusting components 84 are arranged inside the first movable plate 4 and the second movable plate 6. As Figure 4 shown, this structure is used to place the patient's limb between the two groups of positioning plates 81, and then attach the second magic tape 83 to the patient's body surface through the adjusting component 84, so that the other end of the second magic tape 83 passes through another group of second fixing blocks 82 to fix the patient's limb.

[0021] Further, the linkage component 75 includes a chute 751, a movable block 752, a second rotating shaft 753, a third rotating shaft 754, a movable slot 756 and a limiting block 757. Two groups of chutes 751 are opened on both inner sides of the fixed plate 3. The other end of the connecting rod 72 is connected with a movable block 752. A second rotating shaft 753 is inserted into the movable block 752. The connecting rod 72 is rotationally connected to the upper end of the movable block 752 through the second rotating shaft 753. A third rotating shaft 754 is fixedly connected to the central position of the movable block 752. A slider 755 is rotationally connected to the outside of the third rotating shaft 754. The slider 755 is located in the chute 751 and has a diameter adapted to the chute 751. A movable slot 756 is opened in the fixed plate 3. The diameter of the movable slot 756 is adapted to the movable block 752. Limiting blocks 757 are fixedly connected to the inner wall of the movable slot 756 at equal intervals at the connection slot 74. The cross-sections of the bottom of the movable block 752 and the limiting block 757 are both right-angled triangles. As Figure 7 shown, when the first movable plate 4 drives the connecting rod 72 to be lifted upward, this structure is used to make the other end of the connecting rod 72 pull the movable block 752 to move along the chute 751 through the slider 755. After the first movable plate 4 is adjusted to an appropriate height, the limb naturally hangs down. Under the rotational connection of the second rotating shaft 753 and the third rotating shaft 754, the upper end of the movable block 752 inclines towards the inside of the movable slot 756, and at the same time the lower end contacts the limiting block 757 to limit the movable block 752 and support the first movable plate 4.

[0022] Further, the adjusting component 84 includes a fourth rotating shaft 841, a first torsion spring 842 and a clamping slot 843. Fourth rotating shafts 841 are fixedly connected to the left and right sides of the positioning plate 81. A first torsion spring 842 is sleeved on the outer surface of the fourth rotating shaft 841. The two ends of the first torsion spring 842 are respectively connected with the first movable plate 4 and the positioning plate 81. Clamping slots 843 are opened at the front and rear sides of the first movable plate 4 and the second movable plate 6 at the positioning plate 81. The clamping slots 843 are rectangular. Under the limiting action of the clamping slots 843, the positioning plate 81 is always kept in an open state. As Figure 8 shown, when the patient's limb is placed on the surfaces of the first movable plate 4 and the second movable plate 6, when the limb descends, the positioning plates 81 on both sides are pushed to rotate outwards through the fourth rotating shaft 841, and at the same time the first torsion spring 842 deforms. After the limb fits on the surface of the first movable plate 4 or the second movable plate 6, under the restoring action of the first torsion spring 842, the positioning plates 81 are pushed to rotate inwards to fit the patient's limb, which is convenient for patients with different arm circumferences to use and improves the applicability of the device.

[0023] Further, a locking component 9 is provided at the connection between the first movable plate 4 and the second movable plate 6. The locking component 9 includes a fifth rotating shaft 91, a ratchet wheel 92, a sixth rotating shaft 93, a limiting plate 94, a second torsion spring 95 and a movable rod 96. The bottom of the second movable plate 6 is fixedly connected with the fifth rotating shaft 91, and the outer side of the fifth rotating shaft 91 is fixedly connected with the ratchet wheel 92. The bottom of the first movable plate 4 is rotatably connected with the sixth rotating shaft 93, and the outer side of the sixth rotating shaft 93 is fixedly connected with the limiting plate 94. The outer surface of the sixth rotating shaft 93 is sleeved with the second torsion spring 95, and the two ends of the second torsion spring 95 are respectively connected with the first movable plate 4 and the limiting plate 94. The inner wall of the limiting plate 94 is fixedly connected with teeth meshing with the ratchet wheel 92. The outer side of the bottom of the first movable plate 4 is movably connected with the movable rod 96, and the movable rod 96 is located on the left side of the limiting plate 94. As Figure 5 shown, this structure is used to change the included angle between the second movable plate 6 and the first movable plate 4 when adjusting the limb position. The second movable plate 6 drives the ratchet wheel 92 to rotate clockwise through the fifth rotating shaft 91. When the ratchet wheel 92 rotates, the teeth at the ratchet wheel 92 push the teeth at the limiting plate 94. Under the action of the sixth rotating shaft 93, the limiting plate 94 rotates outward, and the second torsion spring 95 deforms. Under the elastic action of the second torsion spring 95, the limiting plate 94 is inserted back into the gap of the ratchet wheel 92 again. Repeating this process, as the ratchet wheel 92 rotates, the limiting plate 94 continuously swings and makes a sound, enabling the patient or medical staff to judge the change in the angle of the second movable plate 6 from the sense of touch and vision. When it is necessary to rotate the second movable plate 6 counterclockwise, the movable rod 96 needs to be pressed. The movable rod 96 pushes the limiting plate 94 to rotate, disengaging the teeth at the limiting plate 94 from the gap of the ratchet wheel 92, so that the second movable plate 6 can rotate counterclockwise.

[0024] Further, the bottom of the fifth rotating shaft 91 is fixedly connected with an indicating disk 97, and an observation hole 98 is opened at the bottom of the first movable plate 4. A scale is arranged on the surface of the indicating disk 97. As Figure 6 shown, this structure is used to drive the indicating disk 97 to rotate through the fifth rotating shaft 91 when the second movable plate 6 rotates, and judge the rotation angle of the second movable plate 6 by observing the scale on the surface of the indicating disk 97 through the observation hole 98.

[0025] Further, two groups of third fixing blocks 10 are fixedly connected to the front and rear sides of the outer surface of the bottom group of protective shells 1, and a third magic tape 11 is movably connected to the surface of the third fixing blocks 10. As Figure 2 shown, this structure is used, through the setting of the third fixing blocks 10 and the third magic tape 11, in cooperation with the protective shell 1 and the first magic tape 2, to disperse the pressure to areas such as the collarbone and upper body through multiple support positions and a large support surface, reducing the risk of axillary / shoulder joint nerve compression.

[0026] Furthermore, protective pads 85 are fixedly connected to the surfaces of the protective shell 1, the first movable plate 4, and the second movable plate 6. The protective pads 85 are made of breathable materials. As Figure 4 shown, this structure is used to improve the comfort of patients through the setting of the protective pads 85.

[0027] Working principle: When in use, as Figure 1 and Figure 2 shown, the protective shell 1 is attached to the body surface of the patient, and then the first magic tape 2 and the third magic tape 11 are used to fit and fix around the corresponding positions. As Figure 4 and Figure 8 shown, when the patient's limb is placed on the surfaces of the first movable plate 4 and the second movable plate 6, when the limb descends, the fourth rotating shaft 841 pushes the positioning plates 81 on both sides to rotate outward, and at the same time deforms the first torsion spring 842. After the limb fits the surface of the first movable plate 4 or the second movable plate 6, under the restoring action of the first torsion spring 842, the positioning plate 81 is pushed to rotate inward to fit the patient's limb. Then, the second magic tape 83 is attached to the patient's body surface through the adjusting assembly 84, and the other end of the second magic tape 83 passes through another set of second fixing blocks 82 to fix the patient's limb. As Figure 3 and Figure 7 shown, when it is necessary to lift the limb, first insert the bolt 73 into the connection hole between the first fixing block 71 and the connecting rod 72, and then drive the connecting rod 72 to move upward along the connection groove 74 by the first rotating shaft 5 of the first movable plate 4, so that the other end of the connecting rod 72 pulls the movable block 752 to move along the sliding groove 751 through the slider 755. After the first movable plate 4 is adjusted to the appropriate height, let the limb hang naturally. Under the rotational connection of the second rotating shaft 753 and the third rotating shaft 754, the upper end of the movable block 752 inclines towards the inside of the movable groove 756, and at the same time the lower end contacts the limiting block 757 to limit the movable block 752 and support the first movable plate 4. As Figure 5 and Figure 6As shown in the figure, when adjusting the limb position, the angle between the second movable plate 6 and the first movable plate 4 changes. The second movable plate 6 drives the ratchet 92 to rotate clockwise through the fifth rotating shaft 91. When the ratchet 92 rotates, the teeth of the ratchet 92 push the teeth of the limiting plate 94. Under the action of the sixth rotating shaft 93, the limiting plate 94 rotates outwards, and the second torsion spring 95 deforms. Under the elastic action of the second torsion spring 95, the limiting plate 94 is inserted back into the gap of the ratchet 92 again. Repeating this process, as the ratchet 92 rotates, the limiting plate 94 continuously swings to make a sound, enabling the patient or medical staff to judge from the sense of touch and vision that the angle of the second movable plate 6 has changed. When it is necessary to rotate the second movable plate 6 counterclockwise, the movable rod 96 needs to be pressed. The movable rod 96 pushes the limiting plate 94 to rotate, disengaging the teeth of the limiting plate 94 from the gap of the ratchet 92, so that the second movable plate 6 can rotate counterclockwise. When the second movable plate 6 rotates, it drives the indicating disc 97 to rotate. By observing the scale on the surface of the indicating disc 97 through the observation hole 98, the rotation angle of the second movable plate 6 is judged. The above is the entire working principle of the present invention.

[0028] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claims involved.
