Description

Technical Field

[0001] This application relates to the technical field of medical devices, and particularly to an upper limb rehabilitation device for treating scapulohumeral periarthritis. Background Art

[0002] Scapulohumeral periarthritis is a common disease mainly characterized by shoulder joint pain and limited mobility. There may be extensive tenderness in the shoulder joint, radiating to the neck and elbow, and varying degrees of deltoid muscle atrophy may also occur. If not effectively treated, it will affect the functional activities of the shoulder joint.

[0003] Therefore, after scapulohumeral periarthritis surgery, rehabilitation training is required to improve the joint mobility.

[0004] However, in the prior art, most of the rehabilitation training devices for scapulohumeral periarthritis require patients to stretch forcefully. For patients who have just completed surgery, stretching is likely to exacerbate the condition. Therefore, there is a need to provide a device that can assist upper limb movement for adaptation and transition. Summary of the Invention

[0059] Referring to Figures 1 to 6 , as Figure 1 shown, this embodiment provides an upper limb rehabilitation device for treating scapulohumeral periarthritis. Compared with the prior art in which the patient needs to actively operate, which is prone to cause upper limb injuries due to overtraining, in this application, the patient only needs to place the upper limb on it, and the whole can drive the upper limb to move up and down, thus avoiding the situation of secondary injury to the patient's upper limb. The upper limb rehabilitation device for treating scapulohumeral periarthritis includes: a base 1, a pair of lifting and adjusting mechanisms 4, a repeated lifting mechanism 5 and a wrist fixing mechanism 6. The pair of lifting and adjusting mechanisms 4 are installed on the base 1 at intervals; the repeated lifting mechanism 5 is connected to the lifting and adjusting mechanism 4; the wrist fixing mechanism 6 is connected to the repeated lifting mechanism 5; wherein, the moving block 43 of the lifting and adjusting mechanism 4 drives the repeated lifting mechanism 5 to move up and down, so as to realize the adjustment of the height of the repeated lifting mechanism 5.

[0062] Preferably, in some embodiments, the guide rod 44 is installed inside the bracket 2.

[0063] Preferably, in some embodiments, the first driver is a first motor 41.

[0064] In the embodiment of the present application, the first motor 41 starts to drive the first lead screw 42 to rotate. With the cooperation of the first lead screw nut 45, the moving block 43 can move up and down on the guide rod 44, so that the heights of the repeated lifting mechanism 5 and the wrist fixing mechanism 6 can be adjusted.

[0065] As Figure 4 shown, the repeated lifting mechanism 5 further includes: a first box body 51, a second driver, a reciprocating movement assembly, a pair of guide sliders 512 and a pair of support rods 59. The first box body 51 is connected to the moving block 43; the second driver is installed in the first box body 51; the reciprocating movement assembly is connected to the second driver, and the moving plate 58 is connected above the reciprocating movement assembly; the moving plate 58 is slidably matched with a pair of guide sliders 512; a pair of support rods 59 are connected to the moving plate 58, and the tops of the pair of support rods 59 are connected to the wrist fixing mechanism 6.

[0066] Preferably, in the embodiment of the present application, a pair of through holes 513 are opened at the upper end of the first box body 51. The support rods 59 are slidably matched with the corresponding through holes 513, and the upper ends of the support rods 59 pass through the corresponding through holes 513 and are connected to the second box body 61.

[0067] In the embodiment of the present application, the reciprocating movement assembly includes: a second lead screw 53, a first sliding cylinder 54, a second sliding cylinder 55, a first connecting rod 56 and a second connecting rod 57. The second lead screw 53 is connected to the second driver; the second lead screw 53 is connected to the second lead screw nut 542; the second sliding cylinder 55 is connected to the second lead screw 53 through a third lead screw nut 552, and the first sliding cylinder 54 and the second sliding cylinder 55 are arranged oppositely; the first connecting rod 56 is hinged between the first sliding cylinder 54 and the moving plate 58; the second connecting rod 57 is hinged between the second sliding cylinder 55 and the moving plate 58.

[0070] Preferably, in the embodiment of the present application, a first slider 541 is connected to the bottom of the first sliding cylinder 54, and a second slider 551 is connected to the bottom of the second sliding cylinder 55. Both the first slider 541 and the second slider 551 are slidably engaged with the sliding groove 511 of the first box body 51.

[0071] In the embodiment of the present application, when the second motor 52 rotates forward, it drives the second lead screw 53 to rotate forward. Then, with the cooperation of the second lead screw nut 542 and the third lead screw nut 552, the first sliding cylinder 54 and the second sliding cylinder 55 can approach each other. Thus, the first connecting rod 56 and the second connecting rod 57 will pull the moving plate 58 downward, thereby reducing the height of the wrist fixing mechanism 6. On the contrary, similarly, when the second motor 52 rotates in reverse, it drives the second lead screw 53 to rotate in reverse, and the first sliding cylinder 54 and the second sliding cylinder 55 will move away from each other, thereby pushing the first connecting rod 56 and the second connecting rod 57 to rotate, causing the moving plate 58 to move upward. Thus, the height of the wrist fixing mechanism 6 increases. Therefore, by repeating the process of the second motor 52 rotating forward and then in reverse, the wrist fixing mechanism 6 can move up and down reciprocally, thereby achieving the training effect on the upper limb.

[0073] Preferably, in the embodiment of the present application, a pair of placement grooves 611 and an installation groove 612 are formed in the second box body 61. The pair of placement grooves 611 are located in the installation groove 612, and the placement grooves 611 and the installation groove 612 are connected through a connection hole 613.

[0074] In the embodiment of the present application, the fixing drive component includes: a third driver, a turntable 63, a crank rod 631, and a drive rod 64. The third driver is installed in the second box body 61; the turntable 63 is coaxially installed with the third driver; the crank rod 631 is hinged to the turntable 63; the drive rod 64 is hinged to the crank rod 631, and the drive rod 64 is slidably engaged with the pressure rod 65.

[0075] Preferably, in some embodiments, the third driver is a third motor 62.

[0076] In the embodiment of the present application, taking Figure 6 as an example for illustration, when the third motor 62 starts, the turntable 63 rotates clockwise, so that the driving rod 64 is pushed downward. Under the cooperation of the convex shaft 641 and the through groove 6511, the pressing rod 65 rotates clockwise, so that the pressing plate 661 presses on the upper limb, which is Figure 6 the state of.

[0077] Preferably, in the embodiment of the present application, the pressing rod 65 includes a first rod body 651 and a second rod body 652 which are integrally connected.
