[0002] Breast cancer is one of the most common malignant tumors in women, with the highest incidence rate among all cancers in women, causing significant harm to women's physical and mental health. There are several types of breast cancer surgery: classic radical resection, modified radical resection, and partial mastectomy. These surgeries typically involve the removal of breast tissue and axillary lymph nodes to prevent cancer cells from metastasizing to bones and other organs.
[0003] However, after the operation, patients often develop complications such as upper limb lymphedema and shoulder joint dysfunction; the range of motion of the shoulder joint causes patients to be unable to raise their hands high. Therefore, timely exercise is required after the operation. Rehabilitation exercise is a long-term process. At present, most patients cannot persist in the long-term use of devices to assist the rehabilitation training of the affected limbs, and during the exercise process, patients cannot adjust the devices according to their own recovery conditions, and their practicality is low.

[0028] See also Figures 1 to 7 In an embodiment of the present invention, a functional exercise device for an affected limb is provided, comprising a storage box 1, wherein the storage box 1 is symmetrically provided with two sets of telescopic components along its length direction, wherein the telescopic components each include a rotating rod 2 rotatably mounted on the storage box 1, and the rotating rod 2 is connected to a plug-in rod 3 slidably provided in the rotating rod 2 through an elastic telescopic structure, so that the plug-in rod 3 can elastically telescope relative to the rotating rod 2;
[0029] For details, please refer to Figure 1 The storage box 1 can be detachably mounted on the ground or a seat, thereby facilitating different usage environments. A sponge pad 101 is fixedly mounted on the front of the storage box 1. The sponge pad 101 is used to support the back of the patient during exercise, so that the patient's back can fit more comfortably against the storage box 1 during exercise.
[0030] The elastic telescopic structure includes two groups of internal chambers 201 symmetrically opened in the rotating rod 2, and a sliding rod 11 is fixedly set in each of the internal chambers 201. A connecting rod 302 is fixedly set on the plug rod 3, and an abutment plate 303 is fixedly set on the end of the connecting rod 302 away from the plug rod 3. A second spring 12 is also slidably set on the sliding rod 11, and one end of the second spring 12 abuts against the abutment plate 303, and the other end abuts against the cavity wall of the internal chamber 201;
[0031] For details, please refer to Figure 5 In the initial state, the second spring 12 is in a compressed state. The compressed second spring 12 will push the abutment plate 303 close to the rotation center of the rotating rod 2. At this time, the distance between the gripping roller 301 fixed on the connecting rod 3 and the rotation center of the rotating rod 2 is the shortest. When the patient needs to exercise, he grips the gripping roller 301 and then extends his forearm outward along the length direction of the rotating rod 2. The force during the extension will drive the connecting rod 3 to extend outward, so that the device can be suitable for patients with different arm lengths to exercise, thereby improving the overall practicality of the device.
[0032] For further information, see Figure 2 、 Figure 3 、 Figure 4 、 Figure 6Two sets of guide rods 9 are fixedly provided in the storage box 1, and a lifting sleeve 5 is slidably provided on the guide rod 9. The lifting sleeve 5 is connected to a sliding member slidably provided on the rotating rod 2. When the rotating rod 2 is subjected to force and rotates relative to the storage box 1, the lifting sleeve 5 will descend relative to the guide rod 9;
[0033] For details, please refer to Figure 2 、 Figure 3 A T-shaped block 501 is fixedly provided on the above-mentioned lifting sleeve 5, and the T-shaped block 501 is slidably set in the T-shaped slot 103 opened on the inner wall of the storage box 1. With the cooperation of the T-shaped block 501 and the T-shaped slot 103, the above-mentioned lifting sleeve 5 can only be lifted and lowered along the axial direction of the guide rod 9.
[0034] The sliding member includes a slider 10, which is slidably connected to a slide rail 202 fixedly provided on the rotating rod 2, and a protrusion 1001 is fixedly provided on the slider 10, and the protrusion 1001 is connected to a guide member fixedly provided in the storage box 1;
[0035] The guide members are symmetrically arranged in two groups along the length direction of the storage box 1, including a fixed plate 4 arranged in the storage box 1, and the fixed plate 4 is provided with an engaging groove, and the engaging groove includes an arc groove 401 and a diameter-reducing groove 402;
[0036] For details, please refer to Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 The lifting sleeve 5 is connected to the slider 10 slidably arranged on the rotating rod 2 through the hinge rod 6. In particular, a gasket 901 is formed on the guide rod 9, and a first spring 7 is slidably arranged on the guide rod 9. One end of the first spring 7 abuts against the force adjustment component, and the other end abuts against the lifting sleeve 5. In the initial state, the first spring 7 is in a compressed state. The first spring 7 in the compressed state will push the lifting sleeve 5 to fit with the gasket 901. At this time, under the cooperation between the fixed-length hinge rod 6 and the slider 10 and the arc groove 401, the rotating rod 2 will remain parallel to the ground; when the patient needs to exercise, standing Alternatively, the patient can sit in front of the storage box 1, hold the grip roller 301 until the upper arm and the forearm are parallel to the ground, and then swing the arm downward. At this time, the swinging force will drive the rotating rod 2 to rotate toward the ground. During the rotation process, due to the connection effect of the hinged rod 6, the rotating rod 2 will force the lifting sleeve 5 to descend along the axial direction of the guide rod 9. During the descent process, the elastic potential energy stored in the first spring 7 needs to be overcome so that the lifting sleeve 5 can descend along the axial direction of the guide rod 9. Through this force confrontation training, on the one hand, the flexibility of the patient's shoulder joint can be increased, and on the other hand, the patient's arm muscles can be trained, thereby preventing the patient's arm muscles from atrophying.
[0037] Furthermore, a functional exercise device for an affected limb further includes a strength adjustment component, which is disposed in the storage box 1 and connected to the lifting sleeve 5. When the strength adjustment component is actuated, the magnitude of the force required for the rotation of the rotating rod 2 can be controlled.
[0038] The force adjustment assembly includes a sleeve 8, an outer thread 801 is formed on the inner wall of the sleeve 8, and the outer thread 801 is adapted to the inner thread 902 formed on the outer wall of the guide rod 9, and a rotating member is rotatably mounted on the sleeve 8;
[0039] The rotating member includes a sleeve ring 13 rotatably mounted on the sleeve 8. The sleeve ring 13 has a plurality of groups of balls 1301 equidistantly arranged along its circumference on one side facing the sleeve 8, and the other side abuts against a first spring 7 slidably arranged on the guide rod 9. The other end of the first spring 7 abuts against the lifting sleeve 5.
[0040] For details, please refer to Figure 6 、 Figure 7 In the initial state, the above-mentioned sleeve 8 is away from the gasket 901. At this time, the distance between the lifting sleeve 5 and the sleeve ring 13 is the largest, and the elastic potential energy stored in the first spring 7 is the smallest. Therefore, in this case, the patient needs to have the least force to swing his arm, which is suitable for patients to perform initial exercises. When the patient gradually enters the late stage of recovery, the sleeve 8 is rotated by the leading grooves 102 on the left and right sides of the storage box 1. At this time, under the cooperation of the internal thread 902 and the external thread 801, the sleeve 8 will spirally rise along the guide rod 9, and in the process of the sleeve 8 spirally rising, the ball 1301 will cause the sleeve 8 to rotate relative to the sleeve ring 13, so that the sleeve ring 13 rises along the axis direction of the guide rod 9. The rising sleeve ring 13 will further compress the first spring 7, thereby changing the initial reserve elastic potential energy of the first spring 7. At this time, the force required by the patient will increase when exercising, which is suitable for patients in different recovery stages to perform exercise on the affected limb;
[0041] In particular, when the patient presses down the rotating rod 2, the descending distance of the lifting sleeve 5 is always constant, so that the patient's strength during exercise can be adjusted. Specifically, when the rotating rod 2 rotates, it will first push the lifting sleeve 5 downward to slide along the T-slot 103. During this sliding process, the protruding post 1001 on the slider 10 will slide along the arc groove 401 until the lifting sleeve 5 slides to the end of the stroke of the T-slot 103, and the protruding post 1001 just slides to the connection between the reducing groove 402 and the arc groove 401. Then, the rotating rod 2 is continued to be rotated, and the protruding post 1001 will slide along the arc groove 401. The reducing groove 402 slides to allow the rotating rod 2 to further deflect toward the ground. This process requires the patient to maintain the force applied at this time, thereby exercising the atrophied muscles of the patient's arm. After the protruding column 1001 moves to the end of the stroke of the reducing groove 402, the rotation angle of the rotating rod 2 reaches the maximum; then the patient performs an upward swing action. This process requires the patient to continue to maintain downward pressure to resist the rotating rod 2, but in this process, the force required by the patient will gradually decrease, which can not only exercise the patient's arm, but also provide a certain degree of relaxation to the patient after the exercise.
