Technical Field

[0001] This utility model relates to the field of medical care equipment technology, specifically a shoulder abduction joint training bracket. Background Technology

[0002] Timely exercise after shoulder surgery is crucial for the recovery of joint function. If patients can quickly and systematically begin abduction exercises after shoulder surgery, the recovery period can be significantly shortened, thus restoring normal shoulder function earlier. The shoulder abduction joint training brace is an assistive device specifically designed for patients after shoulder surgery. It provides stable support for patients when performing shoulder abduction movements, ensuring the standard and safety of the movements. By using the training brace, patients can gradually increase the intensity of their exercises in a controlled environment, effectively promoting the recovery and strengthening of the muscles around the joint. In current technology, the shoulder abduction joint training brace can only perform arm raising and lowering exercises at the side of the body, which is relatively limited in function and cannot help patients train their arms at multiple angles and directions, thus limiting the possibility of patients fully recovering joint function in three-dimensional space.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] In existing technologies, shoulder abduction joint training braces can only be used for arm raising and lowering training at the side of the body. Their function is relatively simple and cannot help patients train their arms at multiple angles and directions, thus limiting the possibility of patients fully restoring joint function in three-dimensional space.

[0015] In view of this, the present invention provides a shoulder abduction joint training bracket. Through the cooperation of the lumbar fixation support, the side connecting plate, the support seat, the telescopic rod, the axillary fixation support, the fixation seat, the support connecting plate, the sector plate, the sector limiting groove, the upper arm movable plate, the limiting rod, and the forearm movable plate, a multi-degree-of-freedom adjustment mechanism is added on the basis of the lateral support of the telescopic rod. This allows the upper arm movable plate to rotate around the rotation center of the shoulder joint at a certain angle, while the forearm movable plate can flex and extend around the rotation center of the elbow joint, thereby simulating the natural abduction movement of the arm. This allows patients to perform flexible training at multiple angles and directions, improving the comprehensiveness and targeting of shoulder joint training, enhancing the patient's rehabilitation experience and recovery effect, and thus helping patients recover joint function more quickly.

[0016] Depend on Figure 1-5 It is known that a shoulder abduction joint training bracket includes a lumbar fixation bracket 1, a side connecting plate 2 is provided on the top of the outer side of the lumbar fixation bracket 1, a support seat 3 is movably connected to the outer wall of the side connecting plate 2, a telescopic rod 4 is hinged to the top of the support seat 3, an axillary fixation bracket 5 is provided above the lumbar fixation bracket 1, a fixation seat 6 is provided on the outer wall of the axillary fixation bracket 5, the fixation seat 6 is fixedly connected to the top of the side connecting plate 2, a support connecting plate 7 is hinged to the top of the fixation seat 6, the support connecting plate 7 is hinged to the end of the telescopic rod 4 away from the support seat 3, a fan-shaped plate 8 is fixedly connected to the top of the support connecting plate 7, a fan-shaped limiting groove 9 is provided on both sides of the top of the fan-shaped plate 8, an upper arm movable plate 10 is connected to the top of the fan-shaped plate 8, a limiting rod 11 is provided on both sides of the bottom of the upper arm movable plate 10, the limiting rod 11 is connected to the fan-shaped limiting groove 9, and a forearm movable plate 12 is rotatably connected to the end of the upper arm movable plate 10 away from the fixation seat 6. In the specific implementation process, it is worth noting that, through the cooperation of the lumbar fixation support 1, the side connecting plate 2, the axillary fixation support 5, and the fixation seat 6, the lumbar fixation support 1 and the axillary fixation support 5 are both fixed to the patient's waist and armpit on the same side as the injured shoulder by fixing straps, so that the side connecting plate 2 is stably fitted to the side of the patient's torso, achieving stable wearing of the training frame. Through the cooperation of the lumbar fixation support 1, the side connecting plate 2, the support seat 3, the telescopic rod 4, the axillary fixation support 5, the fixation seat 6, and the support connecting plate 7, the support seat 3 is installed on the side connecting plate 2, and a telescopic rod for supporting training is installed on its top. 4. The other end of the telescopic rod 4 is connected to the support connecting plate 7. By adjusting the extension and retraction of the telescopic rod 4, the support connecting plate 7 can reciprocate around the connection point with the fixed seat 6. The specific type of the telescopic rod 4 can be selected according to actual needs, such as an electric push rod. Through the cooperation between the support connecting plate 7, the sector plate 8, the sector limiting groove 9, the upper arm movable plate 10, and the limiting rod 11, the limiting rod 11 limits the movement within the sector limiting groove 9, thereby achieving the connection between the upper arm movable plate 10 and the sector plate 8, and allowing the upper arm movable plate 10 to rotate at a certain angle. At the same time, the centers of the two sector limiting grooves 9 are both located within the sector limiting groove 9. The shoulder joint rotation center during arm extension ensures that the movement trajectory of the upper arm movement plate 10 is consistent with the natural abduction trajectory of the arm. Through the cooperation between the upper arm movement plate 10 and the forearm movement plate 12, the patient's upper arm and forearm are fixed to the upper arm movement plate 10 and the forearm movement plate 12 respectively. Furthermore, the connection point between the upper arm movement plate 10 and the forearm movement plate 12 is located at the elbow joint rotation center, ensuring that the movement trajectory of the forearm movement plate 12 is consistent with the natural flexion and extension trajectory of the forearm. This is achieved through the lumbar fixation support 1, the side connecting plate 2, the support seat 3, the telescopic rod 4, the axillary fixation support 5, the fixation seat 6, and the support connection... The coordination between the connecting plate 7, the fan-shaped plate 8, the fan-shaped limiting groove 9, the upper arm movable plate 10, the limiting rod 11, and the forearm movable plate 12, based on the lateral support of the telescopic rod 4, adds a multi-degree-of-freedom adjustment mechanism, allowing the upper arm movable plate 10 to rotate around the shoulder joint rotation center at a certain angle, while the forearm movable plate 12 can flex and extend around the elbow joint rotation center, thus simulating the natural abduction movement of the arm. This allows patients to perform flexible training at multiple angles and directions, improving the comprehensiveness and targeting of shoulder joint training, enhancing the patient's rehabilitation experience and recovery effect, and thus helping patients recover joint function more quickly. Furthermore, a limiting vertical groove 13 is provided on the outer wall of the side connecting plate 2, and a fixing hole 14 is provided at equal intervals inside the limiting vertical groove 13 in the side connecting plate 2. A movable seat 25 is provided on the outer wall of the waist fixing support 1. The movable seat 25 is connected to the side connecting plate 2 and the limiting vertical groove 13 respectively. The support seat 3 is connected to the limiting vertical groove 13. A first fixing knob 15 is threadedly connected to the inner wall of the support seat 3, and a second fixing knob 16 is threadedly connected to the inner wall of the movable seat 25. Both the first fixing knob 15 and the second fixing knob 16 are connected to the fixing hole 14. In the specific implementation process, it is worth noting that through the cooperation between the side connecting plate 2, support base 3, limiting vertical groove 13, fixing hole 14, first fixing knob 15, second fixing knob 16, and movable seat 25, both support base 3 and movable seat 25 can be adjusted in height on the side connecting plate 2. Furthermore, by inserting the first fixing knob 15 and the second fixing knob 16 into the fixing holes 14 at different positions, the support base 3 and movable seat 25 can be fixed at different heights. This is achieved through the waist fixing support 1, side connecting plate 2, support base 3, telescopic rod 4, limiting vertical groove 13, fixing hole 14, and first fixing knob 15. The cooperation between the fixed knob 15, the second fixed knob 16, and the movable seat 25 allows for adjustment of the height of the lumbar support 1, enabling the lumbar support 1 to be adjusted according to the patient's height. This ensures that the lumbar support 1 can stably support the training frame at the patient's waist, allowing the training frame to better conform to the patient's body. At the same time, by adjusting the height of the support seat 3, the extended telescopic rod 4 can support the patient's arm at different angles, facilitating multi-angle and multi-directional training according to the patient's postoperative recovery, and improving the adaptability and flexibility of the training frame. Furthermore, an adjustment groove 17 is provided on the side of the forearm movable plate 12 away from the upper arm movable plate 10, and a gripping ball 18 is provided on the top of the side of the forearm movable plate 12 away from the upper arm movable plate 10.

In the specific implementation process, it is worth noting that through the cooperation between the forearm movement plate 12, the adjustment groove 17, the gripping ball 18, the vertical bar 19 and the third fixing knob 20, the vertical bar 19 at the bottom of the gripping ball 18 passes through the adjustment groove 17 and is fixed by the third fixing knob 20. This allows the patient to further improve the stability of the arm by gripping the gripping ball 18 during training. At the same time, the position of the gripping ball 18 can be adaptively adjusted according to the comfort of gripping. Furthermore, a transverse fixing strap 21 is fixedly connected to one side of the outer wall of both the waist fixing support 1 and the underarm fixing support 5, and a shoulder fixing strap 22 is fixedly connected to the side of the outer wall of the waist fixing support 1 away from the transverse fixing strap 21. In the specific implementation process, it is worth noting that through the cooperation between the lumbar fixation support 1, the axillary fixation support 5, the transverse fixation strap 21 and the shoulder fixation strap 22, the transverse fixation strap 21 located on one side of the lumbar fixation support 1 and the axillary fixation support 5 is wrapped around the patient's waist, abdomen and chest respectively, and the shoulder fixation strap 22 is wrapped around the patient's other shoulder. Each fixation strap passes through the fixation ring located on the other side and is fixed with Velcro. This allows the lumbar fixation support 1 and the axillary fixation support 5 to be worn stably on the patient's waist and under the armpit, thereby ensuring the stability and safety of the training bracket during use. Furthermore, both the upper arm movable plate 10 and the forearm movable plate 12 are provided with an arc-shaped arm support 23 at their top, and an arm fixing strap 24 is fixedly connected to one side of the arc-shaped arm support 23. In the specific implementation process, it is worth noting that through the cooperation between the upper arm movement plate 10, the forearm movement plate 12, the arc-shaped arm support 23, and the arm fixing strap 24, the arc-shaped arm support 23 supports the patient's arm at the top of the upper arm movement plate 10 and the forearm movement plate 12. By passing the arm fixing strap 24 through the fixing ring on the other side and fixing it with Velcro, the patient's arm is fixed on the arc-shaped arm support 23, which increases the patient's comfort during training and improves the stability of the arm support during training. In addition, the arc-shaped arm support 23 is ergonomically designed, with a soft sponge pad on the inner side, which can better conform to the shape of the patient's arm, further improving the patient's comfort during use and avoiding the pressure on the arm caused by long-term training.
