[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0027] Please see the appendix Figures 1-4 This utility model provides an upper limb exercise device after breast cancer surgery, which includes:

[0028] The lifting seat 1 is used to adjust the height of the rotating arm 2, making it suitable for patients of various heights. The top of the output end of the lifting seat 1 is equipped with symmetrical rotating arms 2 on both sides. One end of the rotating arm 2 is connected to a telescopic sleeve 3, which slides onto the outer surface of the rotating arm 2. The distance between the telescopic sleeve 3 and the outer wall of the rotating arm 2 can be adjusted by the electric telescopic rod 22 connected to the top surface of the rotating arm 2, thereby adjusting the length of the rotating arm 2. This allows the length of the telescopic sleeve 3 and the rotating arm 2 to be suitable for patients with different arm lengths.

[0029] The lifting seat 1 is connected to the rotating arm 2 by a limiting groove 51. A reinforcing filling rod 52 is connected to the center of the inner side of the limiting groove 51. The rotating arm 2 is connected to the lifting seat 1 by an arm drive shaft 53. The arm drive shaft 53 is rotatably connected to the inner side of the limiting groove 51. At the same time, the reinforcing filling rod 52 passes through the inner side of the arm drive shaft 53, which can improve the strength of the connection between the arm drive rod and the inner wall of the limiting groove 51.

[0030] A drive motor 54 is provided on the upper inner side of the limiting groove 51. The output end of the drive motor 54 is connected to a drive gear 55. The inner wall of the arm drive shaft 53 connected to the reinforcing filling rod 52 is fixed with a ring of equally spaced driven tooth blocks 56. The drive motor 54 drives the drive gear 55 to rotate and mesh with the driven tooth blocks 56, which can drive the arm drive shaft 53 to rotate. The rotation of the arm drive shaft 53 can drive the rotation of the rotating arm 2.

[0031] It should be noted that a slot is provided on the upper part of the reinforcing filler rod 52 near the drive gear 55 to provide space for the rotation of the drive gear 55.

[0032] A drive shaft 61 is threaded through one end of the rotating arm 2 and the arm drive shaft 53. One end of the drive shaft 61 is coaxially connected to the drive gear 55, which can synchronously drive the drive shaft 61 to rotate when the drive gear 55 rotates. A drive toothed pulley 62 is connected to the middle of the drive shaft 61. A reversing drive wheel 63 is rotatably connected to the inner side of the end of the telescopic sleeve 3 away from the rotating arm 2. The drive toothed pulley 62 and the reversing drive wheel 63 are connected by a drive toothed belt 67.

[0033] The rotating arm 2 has symmetrical fixing bars 24 fixed on both sides inside. The upper and lower sides of the opposite surfaces of the fixing bars 24 are provided with symmetrical limiting grooves 25. The limiting slider 26 is limited to slide on one side of the limiting groove 25. A pressure spring 27 is fixed at the end of the limiting groove 25 away from the limiting slider 26. The other end of the pressure spring 27 abuts against the outer surface of the limiting slider 26. A rotating gear fixing shaft 66 passes between the two opposite limiting sliders 26. The outer wall of the gear fixing shaft 66 is connected to a telescopic adjusting wheel 64 and an adjusting gear 65 respectively. The lower part of the transmission toothed belt 67 passes through the outside of the telescopic adjusting wheel 64 and the adjusting gear 65.

[0034] By setting the reverse drive group 6, when the rotating arm 2 and the telescopic sleeve 3 are in telescopic movement, the rotating arm 2 can push the limiting slider 26 through the pressure spring 27 and slide the limiting slider 26 inside the limiting groove 25, so as to realize the transmission of the transmission shaft 61 to the reversing transmission wheel 63, and can carry out stable transmission when telescopically extended to any position.

[0035] Furthermore, the transmission shaft 61 is connected to the reversing transmission wheel 63 via the transmission toothed pulley 62 and the transmission toothed belt 67, which can improve the stability of the transmission.

[0036] It should be noted that the reversing drive wheel 63 and the drive belt pulley 62 are both gear drives.

[0037] One end of the handpiece 4 has control buttons 42 arranged at equal intervals on its top surface. The control buttons 42 are electrically connected to the drive motor 54. The rotation angle of the rotating arm 2 can be controlled by the control buttons 42 to assist the upper limb exercise of breast cancer patients after surgery.

[0038] The end of the handplate 4 away from the control button 42 is connected to a reverse shaft 41. The other end of the reverse shaft 41 passes through the inner side of the telescopic sleeve rod 3. The two sides of the reversing transmission wheel 63 are coaxially connected to the wire winding wheel 68. The outer side of the wire winding wheel 68 is connected to the reverse transmission wire 69. The other end of the reverse transmission wire 69 is connected to the outer wall of your rotating shaft.

[0039] Through the transmission of the reverse transmission wire 69, the hand plate 4 can always be kept in a horizontal state when the rotating arm 2 rotates, which is convenient for the patient to operate, and at the same time allows the patient to have a more comfortable angle control button 42.

[0040] It should be noted that the limiting sliders 26 inside the upper and lower limiting grooves 25 inside the fixing strip 24 are located on the inner sides of the limiting grooves 25 respectively.

[0041] It should be noted that the arm plate 43 on one side of the telescopic rod 3 allows the patient's arm to be placed on the upper side, so that the telescopic rod 3 can rotate the patient's arm when it rotates, thus assisting the patient in arm exercise.

[0042] Usage process:

[0043] Adjust the height of the lifting seat 1 according to the patient's height, and then control the electric telescopic rod 22 according to the patient's arm length to adjust the length between the rotating arm 2 and the telescopic sleeve 3 to a suitable length for the patient. Then, place the patient's arm on the top surface of the arm plate 43 and the palm on the top surface of the hand plate 4. When the patient needs to lift up, they can press the control button 42, and the drive motor 54 will drive the rotating arm 2 to rotate, causing the patient's arm to rotate upward and sideways, thus lifting the patient's arm. At the same time, after lifting up, the control button 42 can be pressed to drive the rotating arm 2 to descend, and the patient's arm will move down. Through reciprocating drive, the patient can achieve reciprocating arm lifting exercise.

[0044] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0045] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
