Description

Technical Field

[0001] This utility model relates to the field of rehabilitation equipment technology, specifically a portable ankle orthosis. Background Technology

[0002] The ankle joint is a key part of the human body for weight-bearing and movement. However, due to its complex anatomical structure and high mechanical load, it is easily affected by acute injuries or chronic diseases. Therefore, ankle braces are usually required for rehabilitation treatment and rehabilitation training.

[0003] Traditional ankle orthoses typically use screws to secure the foot. While this provides good fixation and protection, when patients need to perform ankle rehabilitation exercises, external tools are required to loosen the screws to allow for movement and rehabilitation. However, the loosened screws are prone to coming loose during walking. Therefore, a portable ankle orthosis that can be adjusted to fix the ankle according to its condition is needed. Utility Model Content

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.

[0021] Please see Figures 1-4 This utility model provides a technical solution: a portable ankle joint orthosis, including a fixing block 3, a fixing screw 2 threadedly connected to the top of the fixing block 3, a connecting strip 1 threadedly fixed to the fixing block 3 by the fixing screw 2, a connecting cover 5 provided on the top of the fixing block 3, a fixing mechanism for installation provided at the bottom of the connecting cover 5, a knob block 14 provided on the top of the connecting cover 5, a rotating shaft 15 fixedly connected to the bottom of the knob block 14, the rotating shaft 15 rotatably connected to the top of the connecting cover 5, a fixing gear 16 fixedly connected to the bottom end of the rotating shaft 15, a connecting piece 7 provided at the bottom of the connecting cover 5, the side of the fixing gear 16 movably inserted into the inner wall of the fixing groove at the top of the connecting piece 7, a control cover 6 provided on the top of the knob block 14, a positioning rod 13 fixedly connected to the inner wall of the control cover 6, the positioning rod 13 slidably connected to the groove on the outer side of the knob block 14, a slot provided on the top of the connecting cover 5, the bottom end of the positioning rod 13 movably inserted into the inner wall of the slot, allowing for quick adjustment of the movement state of the connecting piece 7.

[0022] Furthermore, the fixing mechanism includes a fixing rod 17 and a fixing insert rod 10. One end of the fixing insert rod 10 is fixedly connected to a connecting block 4, which allows for quick fixing or disassembly of the connecting cover 5, thereby enabling quick replacement of the connecting piece 7. The fixing rod 17 is movably inserted into the top of the fixing block 3, and the fixing insert rod 10 is movably inserted into the sides of the fixing rod 17 and the fixing block 3.

[0023] Furthermore, a limiting slide post 12 is fixedly connected to the top of the inner wall of the control cover 6, so that the inner side of the positioning rod 13 can better fit the groove on the outer side of the knob block 14. A limiting groove is opened inside the top of the knob block 14, and the side of the limiting slide post 12 is slidably connected to the inner wall of the limiting groove.

[0024] Furthermore, a positioning pin 8 is fixedly connected to the top of the fixing block 3, which facilitates the quick docking and fixing of the connecting cover 5, and also increases the resistance to the downward movement of the connecting cover 5. The bottom of the connecting cover 5 is provided with an insertion groove, and the positioning pin 8 is movably inserted into the inner wall of the insertion groove.

[0025] Furthermore, a snap-fit ​​rod 9 is fixedly connected to one side of the fixing block 3, which further improves the stability of the fixing rod 10 when it is inserted. The end of the connecting block 4 away from the fixing rod 10 is movably snapped onto the surface of the snap-fit ​​rod 9.

[0026] Furthermore, a gasket 11 is movably installed at the bottom of the fixing block 3 to reduce the direct wear between the connecting piece 7 and the contact surface of the fixing block 3.

[0027] Furthermore, the bottom end of the rotating shaft 15 is movably inserted into the top of the gasket 11 and the top of the bottom end of the fixing block 3, further improving the stability when the gasket and the connecting piece 7 are in contact.

[0028] Furthermore, the limiting slide 12 is T-shaped to prevent the control cover 6 from disengaging from the knob block 14.

[0029] Working principle: This device can be fixed to the foot and leg sleeve with screws through the connecting strip 1 and connecting piece 7. The style of the connecting piece 7 can be changed to meet the fixation operation of different foot. When the patient needs to replace the connecting piece 7, he only needs to remove the fixing rod 10 from the fixing rod 17 through the connecting block 4 to achieve a quick replacement operation. When the patient needs to adjust the ankle joint angle or needs to perform ankle joint rotation rehabilitation treatment, he can lift the control cover 6 to pull the positioning rod 13 out of the slot at the top of the connecting cover 5. At this time, the connecting piece 7 is in a movable state. When the patient needs to fix the ankle joint, he only needs to press the control cover 6. The control cover 6 limits and fixes the knob block 14 through the positioning rod 13, so that the connecting piece 7 cannot be rotated.
