Description

Technical Field

[0001] The utility model relates to the technical field of ankle joint rehabilitation, in particular to a post-operative ankle joint rehabilitation device. Background Art

[0002] The ankle joint is the smallest and heaviest-bearing joint among the three major weight-bearing joints in the human body. Its flexion, dorsiflexion and surrounding muscle strength directly affect the quality of walking. Rehabilitation training is usually required after ankle surgery to speed up the recovery of the ankle joint. Without weight-bearing exercise on the ankle joint, the surrounding muscle strength will be poor or even atrophy.

[0003] The patient's ankle joint is rotated, stepped on and repositioned for rehabilitation training. The training device requires a large amount of pedaling force, which is relatively stiff and less comfortable, resulting in poor ankle training effect. During ankle training, the foot is unevenly stressed or limited by pain, which can easily cause displacement and disengagement, causing the ankle to fall and suffer secondary injury. Therefore, those skilled in the art provide a postoperative ankle joint rehabilitation device to solve the problems raised in the above background technology. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1 to 4 In an embodiment of the utility model, a postoperative ankle joint rehabilitation device includes a bracket 1, a support frame 2 for supporting is installed on the inner side of the bracket 1, a movable frame 3 is installed on the top of the support frame 2, a pedal frame 4 is installed on the top of the movable frame 3, an elastic member 5 is installed between the movable frame 3 and the pedal frame 4, a plurality of support members arranged in a rectangular shape are installed on the inner side of the support frame 2, a guide block 15 is connected to the other side of the movable frame 3, a guide groove 16 is opened on the other side of the inside of the bracket 1, the guide block 15 is slidably connected to the guide groove 16, and the pedal frame 4 is hinged to the movable frame 3.

[0022] When in use, the support frame 2 can support the movable frame 3 upward, and the guide block 15 on one side of the movable frame 3 slides in the guide groove 16. The guide groove 16 can guide and limit the movable frame 3 through the guide block 15. Multiple support members can support the support frame 2 upward, and the stepping frame 4 on the top of the movable frame 3. The patient sits on the chair and then places his feet on the stepping frame 4, so that the ankle rotates to step on the stepping frame 4, and then the stepping frame 4 rotates around one side of the movable frame 3. At the same time, the elastic member 5 can support the stepping frame 4 so that the stepping frame 4 supports the patient's foot for support and reset.

[0023] In one embodiment, specifically, the airbag 6 is connected to the inner side of the elastic member 5, and the fixed plates 7 are respectively connected to the two sides of the inside of the airbag 6, and the elastic plate 8 is connected between the two fixed plates 7. Three elastic parts 18 are evenly arranged on one side of the airbag 6, and the cross-section of the elastic part 18 is arc-shaped. The fixed plate 7 is fixedly connected to the airbag 6, and the two ends of the elastic plate 8 are respectively fixedly connected to the fixed plate 7.

[0024] Among them, the airbag 6 is made of rubber and is filled with gas. The multiple elastic parts 18 on one side of the airbag 6 can increase the degree of deformation of the airbag 6 to prevent the airbag 6 from being squeezed and damaged. The airbag 6 is squeezed and deformed and then supports the elastic part 5 upward. At the same time, the elastic plate 8 supports the airbag 6 through two fixed plates 7. The elastic plate 8 can pull and limit the airbag 6 through the fixed plate 7 to prevent the airbag 6 from expanding too much, so as to increase the support strength of the deformation of the airbag 6.

[0025] Furthermore, the support member includes a plurality of fixing frames 9 arranged in a rectangular shape and installed at the bottom of the support frame 2. A support rod 10 is slidably connected to the inner side of the fixing frame 9. A guide rod 11 is connected to the bottom of the fixing frame 9. A spring 12 for support is mounted on the outer side of the guide rod 11. The two ends of the spring 12 are respectively fixedly connected to the fixing frame 9 and the support rod 10, and the support rod 10 is slidably connected to the fixing frame 9.

[0026] In one embodiment, specifically, the guide rod 11 in the fixed frame 9 can guide the spring 12 to prevent twisting, and the spring 12 can support the support rod 10 upward, so that the support rod 10 supports the support frame 2 upward, thereby improving the compressive strength of the movable frame 3 when being stepped on.

[0027] Among them, an elastic pad 13 is laid at the bottom of the pedaling frame 4, and an anti-slip pad 14 is laid on the top of the elastic pad 13. A plurality of evenly arranged spring clips 17 are connected to the inner side of the elastic pad 13. The spring clips 17 are fixedly connected to the elastic pad 13. The anti-slip pad 14 on the top of the elastic pad 13 can contact the bottom of the patient's foot to prevent the foot from sliding. The multiple spring clips 17 on the inner side of the elastic pad 13 can increase the compressive strength of the elastic pad 13 to improve the comfort of the patient stepping on the pedaling frame 4.

[0028] The working principle of this utility model:

[0029] When the patient's ankle rotates, the pedal frame 4 is hinged on one side of the movable frame 3, and then the pedal frame 4 squeezes the elastic member 5. The elastic portion 18 on one side of the airbag 6 is deformed by the force, and then the airbag 6 is reset after deformation. At the same time, the elastic plate 8 supports the airbag 6 through the two fixed plates 7, and then the cylinder supports the pedal frame 4 through the support piece, and the sole of the foot presses down the movable frame 3 through the pedal frame 4, and then the movable frame 3 presses down the fixed frame 9 through the support rod 10. At the same time, the movable frame 3 drives the guide block 15 to slide in the guide groove 16, and the spring 12 in the fixed frame 9 supports the support rod 10 upward.

[0030] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them.
