Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and more specifically, to a device for shoulder joint rehabilitation therapy. Background Technology
[0002] The shoulder joint, the most flexible joint in the human body, is composed of the glenohumeral joint, acromioclavicular joint, sternoclavicular joint, and scapulothoracic joint. Its anatomical structure is complex and its stability is relatively poor. According to statistics, shoulder joint diseases account for 22% of all joint diseases, among which rotator cuff tears, frozen shoulder, shoulder dislocation, and postoperative adhesions are particularly common. Effective rehabilitation training is the core means of restoring shoulder joint function, and shoulder arm raising training is a key link in restoring upper limb function. Current mainstream treatment methods mainly rely on physical therapists to manually assist or use mechanical devices to drive joint movement, such as pulley traction devices and CPM machines. Although these methods can provide basic joint movement support, the movement trajectory and speed are fixed, and there is a lack of real-time feedback mechanism. It is impossible to adjust the speed and angle of arm raising training according to the patient's own needs. If the arm raising training is too fast or the arm raising angle is too high, it will cause secondary injury to the patient. Therefore, it needs to be improved. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0029] like Figures 1 to 7 As shown, this utility model provides a device for shoulder joint rehabilitation therapy, comprising:
[0030] The base 1 has a vertical plate 2 fixedly installed on its top. The vertical plate 2 has grooves 3 on the left and right sides of the top front of its top surface.
[0031] The motion mechanism is located inside the slide 3;
[0032] The motion mechanism includes a slider 4, the outer surface of which is slidably connected to the inside of the groove 3. A first gear 8 is movably sleeved inside the slider 4. A rotating rod 5 is fixedly sleeved at the front end of the outer surface of the first gear 8. A telescopic rod 6 is movably sleeved on the outer surface of the rotating rod 5. A handle 7 is movably sleeved inside the bottom end of the telescopic rod 6. A rack 9 is meshed with the outer surface of the first gear 8. A connecting block 10 is fixedly installed on the back of the rack 9. A lifting block 11 is slidably connected to the rear end of the connecting block 10. Limiting blocks 12 are slidably connected to the outer surfaces of the left and right sides of the lifting block 11. The bottom end of the limiting block 12 is fixedly connected to the top end of the base 1.
[0033] Due to the design of the limiting block 12, the lifting block 11 is limited, so that the lifting block 11 can only move up and down. When the lifting block 11 moves downward, it will simultaneously drive the two connecting blocks 10 to move downward. At this time, the two connecting blocks 10 will drive the two racks 9 to move downward respectively. Since the two racks 9 are meshed with the two first gears 8, the two racks 9 drive the two first gears 8 to rotate in the opposite direction around the two sliders 4. At the same time, the two first gears 8 will drive the two telescopic rods 6 and the two handles 7 to rotate in the opposite direction through the two rotating rods 5. At this time, the two handles 7 will lift the patient's arm in the opposite direction.
[0034] Among them, a moving block 14 is fixedly installed on the back of the lifting block 11, and a lead screw 15 is threaded into the inside of the moving block 14.
[0035] Since the lead screw 15 is internally threaded with the moving block 14, when the lead screw 15 rotates, it will drive the lifting block 11 to move up and down as a whole through the moving block 14.
[0036] Among them, a number axis 16 is movably sleeved inside the top of the base 1, the top of the number axis 16 is fixedly connected to the bottom of the lead screw 15, and a second gear 17 is fixedly sleeved at the bottom of the outer surface of the number axis 16.
[0037] Since the bottom end of the number axis 16 is internally connected to the top end of the base 1, when the second gear 17 rotates, it will drive the number axis 16 to rotate around the connection point with the base 1. At this time, the lead screw 15 will rotate under the drive of the number axis 16.
[0038] The outer surface of the rotating rod 5 is provided with several pins 19, and the inside of the pins 19 is connected to a circular groove 18. The outer surface of the circular groove 18 is movably connected to the inside of the telescopic rod 6.
[0039] Since the rotating rod 5 is sleeved inside the telescopic rod 6, the telescopic rod 6 can extend and retract along the outer surface of the rotating rod 5 to accommodate different patients' arm lengths. Due to the design of the pin 19 and the groove 18, the connection between the telescopic rod 6 and the rotating rod 5 can be fixed.
[0040] Among them, a round shaft 20 is movably sleeved inside the bottom end of the back of the vertical plate 2, a driven wheel 21 and a first bevel gear 22 are fixedly sleeved on the outer surface of the round shaft 20, a second bevel gear 23 is meshed on the outer surface of the first bevel gear 22, a third gear 24 is fixedly installed at the bottom end of the second bevel gear 23, a fixed shaft 25 is movably sleeved inside the second bevel gear 23 and the third gear 24, and the front end of the fixed shaft 25 is fixedly connected to the back of the vertical plate 2.
[0041] When the driven wheel 21 rotates, it will drive the round shaft 20 to rotate around the point where it is sleeved with the vertical plate 2. At this time, the round shaft 20 will drive the first bevel gear 22 to rotate. Since the first bevel gear 22 is meshed with the second bevel gear 23, the first bevel gear 22 will drive the third gear 24 to rotate around the point where it is sleeved with the fixed shaft 25 through the second bevel gear 23. Since the outer surface of the third gear 24 is meshed with the outer surface of the second gear 17, the second gear 17 will rotate under the drive of the third gear 24.
[0042] Among them, a fixing plate 28 is fixedly installed at the bottom of the front of the vertical plate 2, and a pedal 29 is movably sleeved inside the front end of the fixing plate 28. A drive wheel 30 is fixedly sleeved on the outer surface of the pedal 29, and the drive wheel 30 is connected to the driven wheel 21 through a transmission belt 31.
[0043] When the patient pedals the pedal 29, it will drive the drive wheel 30 to rotate. At this time, the drive wheel 30 will drive the driven wheel 21 to rotate through the transmission belt 31.
[0044] Among them, a fixing block 26 is fixedly installed on the front of the vertical plate 2, and a cushion 27 is fixedly installed on the top of the fixing block 26.
[0045] The design of the seat cushion 27 will provide support for the patient when pedaling the foot pedal 29.
[0046] Among them, a support rod 32 is fixedly installed on the front of the limiting block 12, a bidirectional screw 33 is movably sleeved inside the front end of the support rod 32, a support block 34 is movably sleeved in the middle of the bidirectional screw 33, the front end of the support block 34 is fixedly connected to the back of the vertical plate 2, and a screwing block 35 is fixedly installed on both the left and right ends of the bidirectional screw 33.
[0047] The design of the support rod 32 and the support block 34 will provide good support for the bidirectional screw 33. The design of the turning block 35 will enable the operator to rotate the bidirectional screw 33 by turning the turning block 35.
[0048] Among them, the outer surface of the bidirectional screw 33 is threaded with a movable block 36, and the interior of the movable block 36 is movably sleeved with the outer surface of the first gear 8.
[0049] Since the interior of the movable block 36 is threadedly connected to the bidirectional screw 33, when the bidirectional screw 33 rotates, it will drive the two movable blocks 36 to move. At this time, the two first gears 8 will move under the drive of the two movable blocks 36. Due to the limitation of the slider 4 inside the slide groove 3, the two first gears 8 will drive the two sliders 4 to move in opposite directions along the interior of the two slide grooves 3, so as to adjust the overall spacing of the two rotating rods 5 to accommodate patients with different shoulder widths.
[0050] The lifting block 11 has a round rod 37 fixedly installed inside, and a spring 13 is movably sleeved on the outer surface of the round rod 37. One end of the spring 13 is fixedly connected to the inside of the lifting block 11, and the other end of the spring 13 is fixedly connected to the outer surface of the connecting block 10.
[0051] Due to the elastic force of the two sets of springs 13, when the two first gears 8 move in opposite directions as a whole, the two sets of springs 13 will drive the two connecting blocks 10 to move in opposite directions along the inside of the lifting block 11. At this time, the two connecting blocks 10 will move in opposite directions on the two racks 9, so that the outer surfaces of the two racks 9 always remain in mesh with the outer surfaces of the two racks 9.
[0052] Working principle and usage process of this utility model:
[0053] When a patient needs shoulder joint rehabilitation training, the patient first sits on the cushion 27. The medical staff then adjusts the two rotating rods 5 according to the patient's shoulder width. The staff then rotates the turning block 35, causing it to rotate the bidirectional screw 33 within the support rod 32 and support block 34. Since the outer surface of the bidirectional screw 33 is threaded onto the outer surfaces of the two movable blocks 36, its rotation drives the two movable blocks 36. These movable blocks 36 then drive the two sliders 4 to slide along the interior of the two sliding grooves 3 via the two first gears 8. The design of the two sliding grooves 3 limits the movement of the two sliders 4. Driven by the two sliding grooves 3, the two rotating rods 5 will move in opposite directions along the interior of the two first gears 8. During this process, the two rotating rods 5 will drive the two handles 7 to move in opposite directions through the two telescopic rods 6, thereby achieving the function of adjusting the overall distance of the two rotating rods 5 according to the body shape of different patients. Due to the design of the two sets of springs 13, when the two first gears 8 move in opposite directions, the two sets of springs 13 will push the two connecting blocks 10, so that the two connecting blocks 10 will move in opposite directions along the interior of the lifting block 11. During this process, the two racks 9 will move in opposite directions under the drive of the two connecting blocks 10, so that the outer surfaces of the two racks 9 will always be meshed with the outer surfaces of the first gears 8.
[0054] Subsequently, medical staff adjust the overall length of the rotating rod 5 and the telescopic rod 6 according to the patient's arm length. Since the inside of the telescopic rod 6 is movably connected to the outer surface of the rotating rod 5, when the medical staff pulls the pin 19 out of the telescopic rod 6, the fixing effect on the connection between the rotating rod 5 and the telescopic rod 6 is released. At this time, the telescopic rod 6 can extend and retract along the outer surface of the rotating rod 5. When the overall length of the rotating rod 5 and the telescopic rod 6 matches the length of the patient's arm, the medical staff aligns the round hole on the telescopic rod 6 with the round groove 18 on the rotating rod 5. Then, the medical staff inserts the pin 19 into the telescopic rod 6 and the round groove 18, connecting the rotating rod 5 and the telescopic rod 6. This achieves the function of adjusting the length of the rotating rod 5 and the telescopic rod 6 according to different patients' arm lengths, thereby improving the applicability of the product.
[0055] When a patient needs rehabilitation training, the medical staff pedals the pedal 29 with both feet. The pedal 29 then drives the drive wheel 30 to rotate. The drive wheel 30 then drives the driven wheel 21 to rotate via the transmission belt 31. The driven wheel 21 then drives the first bevel gear 22 to rotate via the round shaft 20. Since the outer surface of the first bevel gear 22 meshes with the outer surface of the second bevel gear 23, the rotation of the first bevel gear 22 will drive the second bevel gear 23 to rotate. The second bevel gear 23 will then drive the third gear 24 to rotate around its engagement point with the fixed shaft 25. Since the outer surface of the third gear 24 meshes with the outer surface of the second gear 17, the rotation of the third gear 24 will drive the second gear 17 to rotate. At this time, the number axis 16 will rotate around its engagement point with the base 1 under the drive of the second gear 17. The lead screw 15 will then rotate under the drive of the number axis 16. Since the outer surface of the lead screw 15 meshes with the moving block... The internal thread of the screw 14 is connected, so when the screw 15 rotates, it will drive the moving block 14 to move. At this time, the lifting block 11 will move under the drive of the moving block 14. Due to the limit block 12 limiting the lifting block 11, the lifting block 11 can only move up and down. At this time, the lifting block 11 will drive the two racks 9 to move downward through the two connecting blocks 10. Since the outer surfaces of the two racks 9 are respectively meshed with the outer surfaces of the two first gears 8, when the two racks 9 move downward, they will drive the two first gears 8 to rotate in the opposite direction around the two sliders 4. At this time, the two first gears 8 will drive the two telescopic rods 6 to rotate in the opposite direction through the two rotating rods 5. Then, the two telescopic rods 6 will drive the patient's two arms to perform arm raising training through the two handles 7. Since the speed and angle of the patient's arm raising training are determined by the speed and number of times the patient kicks the pedal 29, the function of adjusting the arm raising speed and angle according to the patient's needs is realized.
